  • Servers - Buying New vs Buying Second-hand

    - by Django Reinhardt
    We're currently in the process of adding additional servers to our website. We have a pretty simple topology planned: A Firewall/Router Server infront of a Web Application Server and Database Server. Here's a simple (and technically incorrect) diagram that I used in a previous question to illustrate what I mean: We're now wondering about the specs of our two new machines (the Web App and Firewall servers) and whether we can get away with buying a couple of old servers. (Note: Both machines will be running Windows Server 2008 R2.) We're not too concerned about our Firewall/Router server as we're pretty sure it won't be taxed too heavily, but we are interested in our Web App server. I realise that answering this type of question is really difficult without a ton of specifics on users, bandwidth, concurrent sessions, etc, etc., so I just want to focus on the general wisdom on buying old versus new. I had originally specced a new Dell PowerEdge R300 (1U Rack) for our company. In short, because we're going to be caching as much data as possible, I focussed on Processor Speed and Memory: Quad-Core Intel Xeon X3323 2.5Ghz (2x3M Cache) 1333Mhz FSB 16GB DDR2 667Mhz But when I was looking for a cheap second-hand machine for our Firewall/Router, I came across several machines that made our engineer ask a very reasonable question: If we stuck a boat load of RAM in this thing, wouldn't it do for the Web App Server and save us a ton of money in the process? For example, what about a second-hand machine with the following specs: 2x Dual-Core AMD Opteron 2218 2.6Ghz (2MB Cache) 1000Mhz HT 16GB DDR2 667Mhz Would it really be comparable with the more expensive (new) server above? Our engineer postulated that the reason companies upgrade their servers to newer processors is often because they want to reduce their power costs, and that a 2.6Ghz processor was still a 2.6Ghz processor, no matter when it was made. Benchmarks on various sites don't really support this theory, but I was wondering what server admin thought. Thanks for any advice.

  • Does RAID negatively affect non-RAID devices?

    - by Django Reinhardt
    I am running Windows 8 on an SSD, and it's all running swimmingly, but I want to store documents on two HHDs (not SDDs) running under RAID 1. My motherboard has two SATA controllers, both set to AHCI. On the 3GB/s controller, all four ports are used (1 Bluray Optical Drive, 1 Spare HD, and the 2 I wish to turn into a RAID 1 drive). Windows is on the 6GB/s controller. Like so: So my question is: If I turn these four ports (on the 3GB/s controller) into a RAID controller, will that negatively affect the non-RAID hardware plugged into it? I.e. Will the HDD or Bluray drive be slower/incompatible with being plugged into a non-AHCI controller? Thanks.

  • ASP.NET in Moscow!

    - by Stephen Walther
    I’m traveling to Russia and speaking in Moscow next week at the DevConf. This will be the first time that I have visited Russia, and I know that there is a strong ASP.NET community in Russia, so I am very excited about the trip. I’m speaking at the DevConf (http://www.devconf.ru/). I don’t speak Russian, so the only words that I recognize off the home page of the conference website are ASP.NET and JavaScript (PHP, Perl, Python, and Ruby must be Russian words). I’m giving talks on both ASP.NET Web Forms and ASP.NET MVC: What’s New in ASP.NET 4 Web Forms Learn about the new features just released with ASP.NET 4 Web Forms and Visual Studio 2010 that enable you to be more productive and build better websites. Learn how to take control of your markup, client IDs, and view state. Learn how to take advantage of routing with Web Forms to make your websites more search engine friendly.   What’s New in ASP.NET MVC 2 Come learn about the new features being introduced with ASP.NET MVC 2. Templated helpers allow associating edit and display elements with data types automatically. Areas provide a means of dividing a large Web application into multiple projects. Data annotations allows attaching metadata attributes on a model to control validation. Client validation enables form field validation without the need to perform a roundtrip to the server. Learn how these new features enable you to be more productive when building ASP.NET MVC applications. Hope to see you at the conference next week!

  • Corrupted Views when migrating document libraries from SharePoint 2003 to 2007

    - by Kelly Jones
    A coworker of mine ran into this error recently, while migrating a document library from SharePoint 2003 to 2007: “A WebPartZone can only exist on a page which contains a SPWebPartManager. The SPWebPartManager must be placed before any WebPartZones on the page.” He saw this when he tried to see the All Documents view for the library. After looking into it, we figured out what had happened.  He was migrating documents using the Explorer View in SharePoint.  He had copied the contents of the library from one server (a remote server that we didn’t have administrative access to) to his desktop.  He then opened an Explorer View of the new library and copied the files to it.  Well, it turns out he had copied the hidden “Forms” folder, which contained the files necessary to display the different views for the library. (He had set his explorer to show hidden files, which made them visible.) So, he had copied the 2003 forms to the 2007 library, which are incompatible. We fixed it, by simply deleting the new document library, recreating it, and then copied everything except that hidden Forms folder.  Another option might have been to create a new document library on 2007, and copy the Forms folder from it to the broken library.  Since we didn’t need to save anything in the broken BTW, I confirmed my suspicion with this blog post: http://palmettotq.com/blog/?p=54

  • How should I take being told that I was wrong?

    - by Chris
    On a fairly important project with short timelines I decided to use SubSonic for straight forward data access. I wired up a handful of forms, created matching database tables and POCO's for each and used SubSonic's simple repository mode for the data access. Everything worked well and I was able to bang these forms out pretty quickly and I moved on to other things. Since that time I have heard that using SubSonic was a 'cowboy move' and that it was implemented 'incorrectly' and that 'the person who used it, didn't even know how to use SubSonic'. What I would like to know is, how should I take this? There were and still are no standards for data access at this company, so there is no violation of a standard. The forms worked exactly as requested and saved the data to the database correctly. And with only spending a few days on the forms instead of weeks, saved a lot of time which was used for other functionality in the project. So in light of all of this, I am confused as to what was 'incorrect'. Am I missing something here? Thanks for your answers.

  • Weird 302 Redirects in Windows Azure

    - by Your DisplayName here!
    In IdentityServer I don’t use Forms Authentication but the session facility from WIF. That also means that I implemented my own redirect logic to a login page when needed. To achieve that I turned off the built-in authentication (authenticationMode="none") and added an Application_EndRequest handler that checks for 401s and does the redirect to my sign in route. The redirect only happens for web pages and not for web services. This all works fine in local IIS – but in the Azure Compute Emulator and Windows Azure many of my tests are failing and I suddenly see 302 status codes where I expected 401s (the web service calls). After some debugging kung-fu and enabling FREB I found out, that there is still the Forms Authentication module in effect turning 401s into 302s. My EndRequest handler never sees a 401 (despite turning forms auth off in config)! Not sure what’s going on (I suspect some inherited configuration that gets in my way here). Even if it shouldn’t be necessary, an explicit removal of the forms auth module from the module list fixed it, and I now have the same behavior in local IIS and Windows Azure. strange. <modules>   <remove name="FormsAuthentication" /> </modules> HTH Update: Brock ran into the same issue, and found the real reason. Read here.

  • How to detect crashing tabed webbrowser and handle it?

    - by David Eaton
    I have a desktop application (forms) with a tab control, I assign a tab and a new custom webrowser control. I open up about 10 of these tabs. Each one visits about 100 - 500 different pages. The trouble is that if 1 webbrowser control has a problem it shuts down the entire program. I want to be able to close the offending webbrowser control and open a new one in it's place. Is there any event that I need to subscribe to catch a crashing or unresponsive webbrowser control ? I am using C# on windows 7 (Forms), .NET framework v4 =============================================================== UPDATE: 1 - The Tabbed WebBrowser Example Here is the code I have and How I use the webbrowser control in the most basic way. Create a new forms project and name it SimpleWeb Add a new class and name it myWeb.cs, here is the code to use. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Security.Policy; namespace SimpleWeb { //inhert all of webbrowser class myWeb : WebBrowser { public myWeb() { //no javascript errors this.ScriptErrorsSuppressed = true; //Something we want set? AssignEvents(); } //keep near the top private void AssignEvents() { //assign WebBrowser events to our custom methods Navigated += myWeb_Navigated; DocumentCompleted += myWeb_DocumentCompleted; Navigating += myWeb_Navigating; NewWindow += myWeb_NewWindow; } #region Events //List of events:http://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser_events%28v=vs.100%29.aspx //Fired when a new windows opens private void myWeb_NewWindow(object sender, System.ComponentModel.CancelEventArgs e) { //cancel all popup windows e.Cancel = true; //beep to let you know canceled new window Console.Beep(9000, 200); } //Fired before page is navigated (not sure if its before or during?) private void myWeb_Navigating(object sender, System.Windows.Forms.WebBrowserNavigatingEventArgs args) { } //Fired after page is navigated (but not loaded) private void myWeb_Navigated(object sender, System.Windows.Forms.WebBrowserNavigatedEventArgs args) { } //Fired after page is loaded (Catch 22 - Iframes could be considered a page, can fire more than once. Ads are good examples) private void myWeb_DocumentCompleted(System.Object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs args) { } #endregion //Answer supplied by mo. (modified)? public void OpenUrl(string url) { try { //this.OpenUrl(url); this.Navigate(url); } catch (Exception ex) { MessageBox.Show("Your App Crashed! Because = " + ex.ToString()); //MyApplication.HandleException(ex); } } //Keep near the bottom private void RemoveEvents() { //Remove Events Navigated -= myWeb_Navigated; DocumentCompleted -= myWeb_DocumentCompleted; Navigating -= myWeb_Navigating; NewWindow -= myWeb_NewWindow; } } } On Form1 drag a standard tabControl and set the dock to fill, you can go into the tab collection and delete the pre-populated tabs if you like. Right Click on Form1 and Select "View Code" and replace it with this code. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using mshtml; namespace SimpleWeb { public partial class Form1 : Form { public Form1() { InitializeComponent(); //Load Up 10 Tabs for (int i = 0; i <= 10; i++) { newTab("Test_" + i, "http://wwww.yahoo.com"); } } private void newTab(string Title, String Url) { //Create a new Tab TabPage newTab = new TabPage(); newTab.Name = Title; newTab.Text = Title; //create webbrowser Instance myWeb newWeb = new myWeb(); //Add webbrowser to new tab newTab.Controls.Add(newWeb); newWeb.Dock = DockStyle.Fill; //Add New Tab to Tab Pages tabControl1.TabPages.Add(newTab); newWeb.OpenUrl(Url); } } } Save and Run the project. Using the answer below by mo. , you can surf the first url with no problem, but what about all the urls the user clicks on? How do we check those? I prefer not to add events to every single html element on a page, there has to be a way to run the new urls thru the function OpenUrl before it navigates without having an endless loop. Thanks.

  • Using Lightbox with _Screen

    Although, I have to admit that I discovered Bernard Bout's ideas and concepts about implementing a lightbox in Visual FoxPro quite a while ago, there was no "spare" time in active projects that allowed me to have a closer look into his solution(s). Luckily, these days I received a demand to focus a little bit more on this. This article describes the steps about how to integrate and make use of Bernard's lightbox class in combination with _Screen in Visual FoxPro. The requirement in this project was to be able to visually lock the whole application (_Screen area) and guide the user to an information that should not be ignored easily. Depending on the importance any current user activity should be interrupted and focus put onto the notification. Getting the "meat", eh, source code Please check out Bernard's blog on Foxite directly in order to get the latest and greatest version. As time of writing this article I use version 6.0 as described in this blog entry: The Fastest Lightbox Ever The Lightbox class is sub-classed from the imgCanvas class from the GdiPlusX project on VFPx and therefore you need to have the source code of GdiPlusX as well, and integrate it into your development environment. The version I use is available here: Release GDIPlusX 1.20 As soon as you open the bbGdiLightbox class the first it, VFP might ask you to update the reference to the gdiplusx.vcx. As we have the sources, no problem and you have access to Bernard's code. The class itself is pretty easy to understand, some properties that you do not need to change and three methods: Setup(), ShowLightbox() and BeforeDraw() The challenge - _Screen or not? Reading Bernard's article about the fastest lightbox ever, he states the following: "The class will only work on a form. It will not support any other containers" Really? And what about _Screen? Isn't that a form class, too? Yes, of course it is but nonetheless trying to use _Screen directly will fail. Well, let's have look at the code to see why: WITH This .Left = 0 .Top = 0 .Height = ThisForm.Height .Width = ThisForm.Width .ZOrder(0) .Visible = .F.ENDWITH During the setup of the lightbox as well as while capturing the image as replacement for your forms and controls, the object reference Thisform is used. Which is a little bit restrictive to my opinion but let's continue. The second issue lies in the method ShowLightbox() and introduced by the call of .Bitmap.FromScreen(): Lparameters tlVisiblilty* tlVisiblilty - show or hide (T/F)* grab a screen dump with controlsIF tlVisiblilty Local loCaptureBmp As xfcBitmap Local lnTitleHeight, lnLeftBorder, lnTopBorder, lcImage, loImage lnTitleHeight = IIF(ThisForm.TitleBar = 1,Sysmetric(9),0) lnLeftBorder = IIF(ThisForm.BorderStyle < 2,0,Sysmetric(3)) lnTopBorder = IIF(ThisForm.BorderStyle < 2,0,Sysmetric(4)) With _Screen.System.Drawing loCaptureBmp = .Bitmap.FromScreen(ThisForm.HWnd,; lnLeftBorder,; lnTopBorder+lnTitleHeight,; ThisForm.Width ,; ThisForm.Height) ENDWITH * save it to a property This.capturebmp = loCaptureBmp ThisForm.SetAll("Visible",.F.) This.DraW() This.Visible = .T.ELSE ThisForm.SetAll("Visible",.T.) This.Visible = .F.ENDIF My first trials in using the class ended in an exception - GdiPlusError:OutOfMemory - thrown by the Bitmap object. Frankly speaking, this happened mainly because of my lack of knowledge about GdiPlusX. After reading some documentation, especially about the FromScreen() method I experimented a little bit. Capturing the visible area of _Screen actually was not the real problem but the dimensions I specified for the bitmap. The modifications - step by step First of all, it is to get rid of restrictive object references on Thisform and to change them into either This.Parent or more generic into This.oForm (even better: This.oControl). The Lightbox.Setup() method now sets the necessary object reference like so: *====================================================================* Initial setup* Default value: This.oControl = "This.Parent"* Alternative: This.oControl = "_Screen"*====================================================================With This .oControl = Evaluate(.oControl) If Vartype(.oControl) == T_OBJECT .Anchor = 0 .Left = 0 .Top = 0 .Width = .oControl.Width .Height = .oControl.Height .Anchor = 15 .ZOrder(0) .Visible = .F. EndIfEndwith Also, based on other developers' comments in Bernard articles on his lightbox concept and evolution I found the source code to handle the differences between a form and _Screen and goes into Lightbox.ShowLightbox() like this: *====================================================================* tlVisibility - show or hide (T/F)* grab a screen dump with controls*====================================================================Lparameters tlVisibility Local loControl m.loControl = This.oControl If m.tlVisibility Local loCaptureBmp As xfcBitmap Local lnTitleHeight, lnLeftBorder, lnTopBorder, lcImage, loImage lnTitleHeight = Iif(m.loControl.TitleBar = 1,Sysmetric(9),0) lnLeftBorder = Iif(m.loControl.BorderStyle < 2,0,Sysmetric(3)) lnTopBorder = Iif(m.loControl.BorderStyle < 2,0,Sysmetric(4)) With _Screen.System.Drawing If Upper(m.loControl.Name) == Upper("Screen") loCaptureBmp = .Bitmap.FromScreen(m.loControl.HWnd) Else loCaptureBmp = .Bitmap.FromScreen(m.loControl.HWnd,; lnLeftBorder,; lnTopBorder+lnTitleHeight,; m.loControl.Width ,; m.loControl.Height) EndIf Endwith * save it to a property This.CaptureBmp = loCaptureBmp m.loControl.SetAll("Visible",.F.) This.Draw() This.Visible = .T. Else This.CaptureBmp = .Null. m.loControl.SetAll("Visible",.T.) This.Visible = .F. Endif {loadposition content_adsense} Are we done? Almost... Although, Bernard says it clearly in his article: "Just drop the class on a form and call it as shown." It did not come clear to my mind in the first place with _Screen, but, yeah, he is right. Dropping the class on a form provides a permanent link between those two classes, it creates a valid This.Parent object reference. Bearing in mind that the lightbox class can not be "dropped" on the _Screen, we have to create the same type of binding during runtime execution like so: *====================================================================* Create global lightbox component*==================================================================== Local llOk, loException As Exception m.llOk = .F. m.loException = .Null. If Not Vartype(_Screen.Lightbox) == "O" Try _Screen.AddObject("Lightbox", "bbGdiLightbox") Catch To m.loException Assert .F. Message m.loException.Message EndTry EndIf m.llOk = (Vartype(_Screen.Lightbox) == "O")Return m.llOk Through runtime instantiation we create a valid binding to This.Parent in the lightbox object and the code works as expected with _Screen. Ease your life: Use properties instead of constants Having a closer look at the BeforeDraw() method might wet your appetite to simplify the code a little bit. Looking at the sample screenshots in Bernard's article you see several forms in different colors. This got me to modify the code like so: *====================================================================* Apply the actual lightbox effect on the captured bitmap.*====================================================================If Vartype(This.CaptureBmp) == T_OBJECT Local loGfx As xfcGraphics loGfx = This.oGfx With _Screen.System.Drawing loGfx.DrawImage(This.CaptureBmp,This.Rectangle,This.Rectangle,.GraphicsUnit.Pixel) * change the colours as needed here * possible colours are (220,128,0,0),(220,0,0,128) etc. loBrush = .SolidBrush.New(.Color.FromArgb( ; This.Opacity, .Color.FromRGB(This.BorderColor))) loGfx.FillRectangle(loBrush,This.Rectangle) EndwithEndif Create an additional property Opacity to specify the grade of translucency you would like to have without the need to change the code in each instance of the class. This way you only need to change the values of Opacity and BorderColor to tweak the appearance of your lightbox. This could be quite helpful to signalize different levels of importance (ie. green, yellow, orange, red, etc...) of notifications to the users of the application. Final thoughts Using the lightbox concept in combination with _Screen instead of forms is possible. Already Jim Wiggins comments in Bernard's article to loop through the _Screen.Forms collection in order to cascade the lightbox visibility to all active forms. Good idea. But honestly, I believe that instead of looping all forms one could use _Screen.SetAll("ShowLightbox", .T./.F., "Form") with Form.ShowLightbox_Access method to gain more speed. The modifications described above might provide even more features to your applications while consuming less resources and performance. Additionally, the restrictions to capture only forms does not exist anymore. Using _Screen you are able to capture and cover anything. The captured area of _Screen does not include any toolbars, docked windows, or menus. Therefore, it is advised to take this concept on a higher level and to combine it with additional classes that handle the state of toolbars, docked windows and menus. Which I did for the customer's project.

  • How to become a solid python web developer [closed]

    - by Estarius
    Possible Duplicate: How do I learn Python from zero to web development? I have started Python recently with the goal to become a solid developer to make a web application eventually. However, as time goes by I am wondering if I am being optimal about how I will achieve my goal. I would compare it to a game for example, to be better you must spend time playing and trying new things... However, if you just log in and sit in the lobby chatting you are most likely not progressing. So far, this is my plan (feel free to comment or judge it): Review basic programmation concepts Start coding slowly in Python Once comfortable in Python, learn about web development in Python Learn about those things we heard about: SQLAlchemy, MVC, TDD, Git, Agile (Group project) To achieve these things, I started the Learn python the hard way exercises, which I am doing at the rate of 5 per days. I also started to read Think Python at the same time and planning to move on with Dive into python. As far as my research goes, these documentations along with Python documentation is usually what is the most recommended to learn Python. I consider this to get my point 1 and 2 done. While learning Python is really great, my goal remains to do quality web development. I know there are books about Django etc. however I would like to become comfortable with any Python web development. This means without Framework and with Framework... Any framework, then be able to choose the one which best fits our needs. For this I would like to know if some people have suggestions. Should I just get a book on Django and it should apply to everything ? What would be the best method to go from Python to Web Python and not end up creating crappy code which would turn into nightmares for other programmers ? Then finally, those "things we hear about". While I understand what they all do basically, I am fairly sure that like everything, there are good and wrong ways of making use of them. Should I go through at least a whole book on each before starting to use them or keep it at their respective online documentation ? Are there some kind of documentation which links their use to Python ? Also, from looking at Django and Pyramid they seems to use something else than MVC, while the Django model looks similar, the Pyramid one seems to cut a whole part of it... Is learning MVC still worth it ? Sorry for the wall of text, Thanks in advance !

  • How to create Custom ListForm WebPart

    - by DipeshBhanani
    Mostly all who works extensively on SharePoint (including meJ) don’t like to use out-of-box list forms (DispForm.aspx, EditForm.aspx, NewForm.aspx) as interface. Actually these OOB list forms bind hands of developers for the customization. It gives headache to developers to add just one post back event, for a dropdown field and to populate other fields in NewForm.aspx or EditForm.aspx. On top of that clients always ask such stuff. So here I am going to give you guys a flight for SharePoint Customization world. In this blog, I will explain, how to create CustomListForm WebPart. In my next blogs, I am going to explain easy deployment of List Forms through features and last, guidance on using SharePoint web controls. 1.       First thing, create a class library project through Visual Studio and inherit the class with WebPart class.     public class CustomListForm : WebPart   2.       Declare the public variables and properties which we are going to use throughout the class. You will get to know these once you see them in use.         #region "Variable Declaration"           Table spTableCntl;         FormToolBar formToolBar;         Literal ltAlertMessage;         Guid SiteId;         Guid ListId;         int ItemId;         string ListName;           #endregion           #region "Properties"           SPControlMode _ControlMode = SPControlMode.New;         [Personalizable(PersonalizationScope.Shared),          WebBrowsable(true),          WebDisplayName("Control Mode"),          WebDescription("Set Control Mode"),          DefaultValue(""),          Category("Miscellaneous")]         public SPControlMode ControlMode         {             get { return _ControlMode; }             set { _ControlMode = value; }         }           #endregion     The property “ControlMode” is used to identify the mode of the List Form. The property is of type SPControlMode which is an enum type with values (Display, Edit, New and Invalid). When we will add this WebPart to DispForm.aspx, EditForm.aspx and NewForm.aspx, we will set the WebPart property “ControlMode” to Display, Edit and New respectively.     3.       Now, we need to override the CreateChildControl method and write code to manually add SharePoint Web Controls related to each list fields as well as ToolBar controls.         protected override void CreateChildControls()         {             base.CreateChildControls();               try             {                 SiteId = SPContext.Current.Site.ID;                 ListId = SPContext.Current.ListId;                 ListName = SPContext.Current.List.Title;                   if (_ControlMode == SPControlMode.Display || _ControlMode == SPControlMode.Edit)                     ItemId = SPContext.Current.ItemId;                   SPSecurity.RunWithElevatedPrivileges(delegate()                 {                     using (SPSite site = new SPSite(SiteId))                     {                         //creating a new SPSite with credentials of System Account                         using (SPWeb web = site.OpenWeb())                         {                               //<Custom Code for creating form controls>                         }                     }                 });             }             catch (Exception ex)             {                 ShowError(ex, "CreateChildControls");             }         }   Here we are assuming that we are developing this WebPart to plug into List Forms. Hence we will get the List Id and List Name from the current context. We can have Item Id only in case of Display and Edit Mode. We are putting our code into “RunWithElevatedPrivileges” to elevate privileges to System Account. Now, let’s get deep down into the main code and expand “//<Custom Code for creating form controls>”. Before initiating any SharePoint control, we need to set context of SharePoint web controls explicitly so that it will be instantiated with elevated System Account user. Following line does the job.     //To create SharePoint controls with new web object and System Account credentials     SPControl.SetContextWeb(Context, web);   First thing, let’s add main table as container for all controls.     //Table to render webpart     Table spTableMain = new Table();     spTableMain.CellPadding = 0;     spTableMain.CellSpacing = 0;     spTableMain.Width = new Unit(100, UnitType.Percentage);     this.Controls.Add(spTableMain);   Now we need to add Top toolbar with Save and Cancel button at top as you see in the below screen shot.       // Add Row and Cell for Top ToolBar     TableRow spRowTopToolBar = new TableRow();     spTableMain.Rows.Add(spRowTopToolBar);     TableCell spCellTopToolBar = new TableCell();     spRowTopToolBar.Cells.Add(spCellTopToolBar);     spCellTopToolBar.Width = new Unit(100, UnitType.Percentage);         ToolBar toolBarTop = (ToolBar)Page.LoadControl("/_controltemplates/ToolBar.ascx");     toolBarTop.CssClass = "ms-formtoolbar";     toolBarTop.ID = "toolBarTbltop";     toolBarTop.RightButtons.SeparatorHtml = "<td class=ms-separator> </td>";       if (_ControlMode != SPControlMode.Display)     {         SaveButton btnSave = new SaveButton();         btnSave.ControlMode = _ControlMode;         btnSave.ListId = ListId;           if (_ControlMode == SPControlMode.New)             btnSave.RenderContext = SPContext.GetContext(web);         else         {             btnSave.RenderContext = SPContext.GetContext(this.Context, ItemId, ListId, web);             btnSave.ItemContext = SPContext.GetContext(this.Context, ItemId, ListId, web);             btnSave.ItemId = ItemId;         }         toolBarTop.RightButtons.Controls.Add(btnSave);     }       GoBackButton goBackButtonTop = new GoBackButton();     toolBarTop.RightButtons.Controls.Add(goBackButtonTop);     goBackButtonTop.ControlMode = SPControlMode.Display;       spCellTopToolBar.Controls.Add(toolBarTop);   Here we have use “SaveButton” and “GoBackButton” which are internal SharePoint web controls for save and cancel functionality. I have set some of the properties of Save Button with if-else condition because we will not have Item Id in case of New Mode. Item Id property is used to identify which SharePoint List Item need to be saved. Now, add Form Toolbar to the page which contains “Attach File”, “Delete Item” etc buttons.       // Add Row and Cell for FormToolBar     TableRow spRowFormToolBar = new TableRow();     spTableMain.Rows.Add(spRowFormToolBar);     TableCell spCellFormToolBar = new TableCell();     spRowFormToolBar.Cells.Add(spCellFormToolBar);     spCellFormToolBar.Width = new Unit(100, UnitType.Percentage);       FormToolBar formToolBar = new FormToolBar();     formToolBar.ID = "formToolBar";     formToolBar.ListId = ListId;     if (_ControlMode == SPControlMode.New)         formToolBar.RenderContext = SPContext.GetContext(web);     else     {         formToolBar.RenderContext = SPContext.GetContext(this.Context, ItemId, ListId, web);         formToolBar.ItemContext = SPContext.GetContext(this.Context, ItemId, ListId, web);         formToolBar.ItemId = ItemId;     }     formToolBar.ControlMode = _ControlMode;     formToolBar.EnableViewState = true;       spCellFormToolBar.Controls.Add(formToolBar);     The ControlMode property will take care of which button to be displayed on the toolbar. E.g. “Attach files”, “Delete Item” in new/edit forms and “New Item”, “Edit Item”, “Delete Item”, “Manage Permissions” etc in display forms. Now add main section which contains form field controls.     //Create Form Field controls and add them in Table "spCellCntl"     CreateFieldControls(web);     //Add public variable "spCellCntl" containing all form controls to the page     spRowCntl.Cells.Add(spCellCntl);     spCellCntl.Width = new Unit(100, UnitType.Percentage);     spCellCntl.Controls.Add(spTableCntl);       //Add a Blank Row with height of 5px to render space between ToolBar table and Control table     TableRow spRowLine1 = new TableRow();     spTableMain.Rows.Add(spRowLine1);     TableCell spCellLine1 = new TableCell();     spRowLine1.Cells.Add(spCellLine1);     spCellLine1.Height = new Unit(5, UnitType.Pixel);     spCellLine1.Controls.Add(new LiteralControl("<IMG SRC='/_layouts/images/blank.gif' width=1 height=1 alt=''>"));       //Add Row and Cell for Form Controls Section     TableRow spRowCntl = new TableRow();     spTableMain.Rows.Add(spRowCntl);     TableCell spCellCntl = new TableCell();       //Create Form Field controls and add them in Table "spCellCntl"     CreateFieldControls(web);     //Add public variable "spCellCntl" containing all form controls to the page     spRowCntl.Cells.Add(spCellCntl);     spCellCntl.Width = new Unit(100, UnitType.Percentage);     spCellCntl.Controls.Add(spTableCntl);       TableRow spRowLine2 = new TableRow();     spTableMain.Rows.Add(spRowLine2);     TableCell spCellLine2 = new TableCell();     spRowLine2.Cells.Add(spCellLine2);     spCellLine2.CssClass = "ms-formline";     spCellLine2.Controls.Add(new LiteralControl("<IMG SRC='/_layouts/images/blank.gif' width=1 height=1 alt=''>"));       // Add Blank row with height of 5 pixel     TableRow spRowLine3 = new TableRow();     spTableMain.Rows.Add(spRowLine3);     TableCell spCellLine3 = new TableCell();     spRowLine3.Cells.Add(spCellLine3);     spCellLine3.Height = new Unit(5, UnitType.Pixel);     spCellLine3.Controls.Add(new LiteralControl("<IMG SRC='/_layouts/images/blank.gif' width=1 height=1 alt=''>"));   You can add bottom toolbar also to get same look and feel as OOB forms. I am not adding here as the blog will be much lengthy. At last, you need to write following lines to allow unsafe updates for Save and Delete button.     // Allow unsafe update on web for save button and delete button     if (this.Page.IsPostBack && this.Page.Request["__EventTarget"] != null         && (this.Page.Request["__EventTarget"].Contains("IOSaveItem")         || this.Page.Request["__EventTarget"].Contains("IODeleteItem")))     {         SPContext.Current.Web.AllowUnsafeUpdates = true;     }   So that’s all. We have finished writing Custom Code for adding field control. But something most important is skipped. In above code, I have called function “CreateFieldControls(web);” to add SharePoint field controls to the page. Let’s see the implementation of the function:     private void CreateFieldControls(SPWeb pWeb)     {         SPList listMain = pWeb.Lists[ListId];         SPFieldCollection fields = listMain.Fields;           //Main Table to render all fields         spTableCntl = new Table();         spTableCntl.BorderWidth = new Unit(0);         spTableCntl.CellPadding = 0;         spTableCntl.CellSpacing = 0;         spTableCntl.Width = new Unit(100, UnitType.Percentage);         spTableCntl.CssClass = "ms-formtable";           SPContext controlContext = SPContext.GetContext(this.Context, ItemId, ListId, pWeb);           foreach (SPField listField in fields)         {             string fieldDisplayName = listField.Title;             string fieldInternalName = listField.InternalName;               //Skip if the field is system field or hidden             if (listField.Hidden || listField.ShowInVersionHistory == false)                 continue;               //Skip if the control mode is display and field is read-only             if (_ControlMode != SPControlMode.Display && listField.ReadOnlyField == true)                 continue;               FieldLabel fieldLabel = new FieldLabel();             fieldLabel.FieldName = listField.InternalName;             fieldLabel.ListId = ListId;               BaseFieldControl fieldControl = listField.FieldRenderingControl;             fieldControl.ListId = ListId;             //Assign unique id using Field Internal Name             fieldControl.ID = string.Format("Field_{0}", fieldInternalName);             fieldControl.EnableViewState = true;               //Assign control mode             fieldLabel.ControlMode = _ControlMode;             fieldControl.ControlMode = _ControlMode;             switch (_ControlMode)             {                 case SPControlMode.New:                     fieldLabel.RenderContext = SPContext.GetContext(pWeb);                     fieldControl.RenderContext = SPContext.GetContext(pWeb);                     break;                 case SPControlMode.Edit:                 case SPControlMode.Display:                     fieldLabel.RenderContext = controlContext;                     fieldLabel.ItemContext = controlContext;                     fieldLabel.ItemId = ItemId;                       fieldControl.RenderContext = controlContext;                     fieldControl.ItemContext = controlContext;                     fieldControl.ItemId = ItemId;                     break;             }               //Add row to display a field row             TableRow spCntlRow = new TableRow();             spTableCntl.Rows.Add(spCntlRow);               //Add the cells for containing field lable and control             TableCell spCellLabel = new TableCell();             spCellLabel.Width = new Unit(30, UnitType.Percentage);             spCellLabel.CssClass = "ms-formlabel";             spCntlRow.Cells.Add(spCellLabel);             TableCell spCellControl = new TableCell();             spCellControl.Width = new Unit(70, UnitType.Percentage);             spCellControl.CssClass = "ms-formbody";             spCntlRow.Cells.Add(spCellControl);               //Add the control to the table cells             spCellLabel.Controls.Add(fieldLabel);             spCellControl.Controls.Add(fieldControl);               //Add description if there is any in case of New and Edit Mode             if (_ControlMode != SPControlMode.Display && listField.Description != string.Empty)             {                 FieldDescription fieldDesc = new FieldDescription();                 fieldDesc.FieldName = fieldInternalName;                 fieldDesc.ListId = ListId;                 spCellControl.Controls.Add(fieldDesc);             }               //Disable Name(Title) in Edit Mode             if (_ControlMode == SPControlMode.Edit && fieldDisplayName == "Name")             {                 TextBox txtTitlefield = (TextBox)fieldControl.Controls[0].FindControl("TextField");                 txtTitlefield.Enabled = false;             }         }         fields = null;     }   First of all, I have declared List object and got list fields in field collection object called “fields”. Then I have added a table for the container of all controls and assign CSS class as "ms-formtable" so that it gives consistent look and feel of SharePoint. Now it’s time to navigate through all fields and add them if required. Here we don’t need to add hidden or system fields. We also don’t want to display read-only fields in new and edit forms. Following lines does this job.             //Skip if the field is system field or hidden             if (listField.Hidden || listField.ShowInVersionHistory == false)                 continue;               //Skip if the control mode is display and field is read-only             if (_ControlMode != SPControlMode.Display && listField.ReadOnlyField == true)                 continue;   Let’s move to the next line of code.             FieldLabel fieldLabel = new FieldLabel();             fieldLabel.FieldName = listField.InternalName;             fieldLabel.ListId = ListId;               BaseFieldControl fieldControl = listField.FieldRenderingControl;             fieldControl.ListId = ListId;             //Assign unique id using Field Internal Name             fieldControl.ID = string.Format("Field_{0}", fieldInternalName);             fieldControl.EnableViewState = true;               //Assign control mode             fieldLabel.ControlMode = _ControlMode;             fieldControl.ControlMode = _ControlMode;   We have used “FieldLabel” control for displaying field title. The advantage of using Field Label is, SharePoint automatically adds red star besides field label to identify it as mandatory field if there is any. Here is most important part to understand. The “BaseFieldControl”. It will render the respective web controls according to type of the field. For example, if it’s single line of text, then Textbox, if it’s look up then it renders dropdown. Additionally, the “ControlMode” property tells compiler that which mode (display/edit/new) controls need to be rendered with. In display mode, it will render label with field value. In edit mode, it will render respective control with item value and in new mode it will render respective control with empty value. Please note that, it’s not always the case when dropdown field will be rendered for Lookup field or Choice field. You need to understand which controls are rendered for which list fields. I am planning to write a separate blog which I hope to publish it very soon. Moreover, we also need to assign list field specific properties like List Id, Field Name etc to identify which SharePoint List field is attached with the control.             switch (_ControlMode)             {                 case SPControlMode.New:                     fieldLabel.RenderContext = SPContext.GetContext(pWeb);                     fieldControl.RenderContext = SPContext.GetContext(pWeb);                     break;                 case SPControlMode.Edit:                 case SPControlMode.Display:                     fieldLabel.RenderContext = controlContext;                     fieldLabel.ItemContext = controlContext;                     fieldLabel.ItemId = ItemId;                       fieldControl.RenderContext = controlContext;                     fieldControl.ItemContext = controlContext;                     fieldControl.ItemId = ItemId;                     break;             }   Here, I have separate code for new mode and Edit/Display mode because we will not have Item Id to assign in New Mode. We also need to set CSS class for cell containing Label and Controls so that those controls get rendered with SharePoint theme.             spCellLabel.CssClass = "ms-formlabel";             spCellControl.CssClass = "ms-formbody";   “FieldDescription” control is used to add field description if there is any.    Now it’s time to add some more customization,               //Disable Name(Title) in Edit Mode             if (_ControlMode == SPControlMode.Edit && fieldDisplayName == "Name")             {                 TextBox txtTitlefield = (TextBox)fieldControl.Controls[0].FindControl("TextField");                 txtTitlefield.Enabled = false;             }   The above code will disable the title field in edit mode. You can add more code here to achieve more customization according to your requirement. Some of the examples are as follow:             //Adding post back event on UserField to auto populate some other dependent field             //in new mode and disable it in edit mode             if (_ControlMode != SPControlMode.Display && fieldDisplayName == "Manager")             {                 if (fieldControl.Controls[0].FindControl("UserField") != null)                 {                     PeopleEditor pplEditor = (PeopleEditor)fieldControl.Controls[0].FindControl("UserField");                     if (_ControlMode == SPControlMode.New)                         pplEditor.AutoPostBack = true;                     else                         pplEditor.Enabled = false;                 }             }               //Add JavaScript Event on Dropdown field. Don't forget to add the JavaScript function on the page.             if (_ControlMode == SPControlMode.Edit && fieldDisplayName == "Designation")             {                 DropDownList ddlCategory = (DropDownList)fieldControl.Controls[0];                 ddlCategory.Attributes.Add("onchange", string.Format("javascript:DropdownChangeEvent('{0}');return false;", ddlCategory.ClientID));             }    Following are the screenshots of my Custom ListForm WebPart. Let’s play a game, check out your OOB List forms of SharePoint, compare with these screens and find out differences.   DispForm.aspx:   EditForm.aspx:   NewForm.aspx:   Enjoy the SharePoint Soup!!! ­­­­­­­­­­­­­­­­­­­­

  • SH404SEF URLs in Joomla 1.5

    - by Tao Bellamine
    I have two modules to play with urls, the global configuration module and the sh404sef module. The global config is set to "Sef urls: YES" and "mod rewrite enabled: YES" and the sh404sef is set "url optimization: NO". My problem is, even with "Sef urls" set in the global config, my urls still don't seem to be that "user friendly" so I turn on the "Url optimization" using the sh404sef module, and I get better descriptive urls. However, the problem I inherit from doing this is that my dynamically populated chronoforms get messed up (only the chrono forms, other forms are fine); These forms are now showing up at the homepage instead of their own reserved page. Here's an example: Old form "GOOD" url: http://www.mycraftwork.com/index.php?option=com_content&view=article&id=94 New optimized "BAD" URL: http://www.mycraftwork.com/handthrown-pottery/alladin-teapot/index.php?option=com_content&view=article&id=94 Any help would be GREATLY appreciated! I can even turn the sh404sef on and off if some people are interested in seeing the issue LIVE. Thanks!! Tao Bellamine

  • it is a good approach to implement dependency injection in a desktop app?

    - by luis_laurent
    Well, the thing is that I am just about to create a Desktop App (with .NET windows forms) And now I just wonder if it would be really a wise choise to use any IoC (StructureMap,Ninject,Spring .Net), I have used them before for Asp.Net web applications but what makes me doubt now is the fact that working with windows forms my business entities will persist when I navigate through tabs and unlike than web forms or mvc apps where it would be necesary to inject my business entity for every new request that is performed, I mean this because of the Asp.Net page life cycle where is performed the initialization and controls instantiation. Maybe I am misunderstanding the point of using an IoC, so please tell me what do you think would be a better choise?

  • Apache virtualhost - only apply script if file does not exist in document root

    - by Brett Thomas
    Sorry for the newbie apache question. I'm wondering if it's possible to set up the following non-conventional apache virtualhost (for a Django app): -- If a file exists in the DocumentRoot (/var/www) it will be shown. So if /var/www/foo.html exists, then it can be seen at www.example.com/foo.html. -- If file does not exist, it is served via a virtualhost. I'm using mod_wsgi with a WSGIScriptAlias directive that points to a Django app. So if there is no /var/www/bar.html, www.example.com/bar.html will be passed to the Django app, which may or may not be a 404 error. One option is to create an Alias for each individual file/directory, but people want to be able to post a file without adding an alias, and we want to keep the above URL structure for legacy reasons. Simplified Virtualhost is: <VirtualHost *:80> ServerName www.example.com DocumentRoot /var/www WSGIScriptAlias / /path/to/django.wsgi <Directory /path/to/app> Order allow,deny Allow from all </Directory> Alias /hi.html /var/www/hi.html </VirtualHost> The goal is to have www.example.com/hi.html work as above, without the Alias line

  • Why is lighttpd and fastcgi keeping sending me the *.scgi file instead of the website content?

    - by e-satis
    I have the following config: server.modules = ( "mod_compress", "mod_access", "mod_alias", "mod_rewrite", "mod_redirect", "mod_secdownload", "mod_h264_streaming", "mod_flv_streaming", "mod_accesslog", "mod_auth", "mod_status", "mod_expire", "mod_fastcgi" ) [...] fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/var/tmp/lighttpd/php-fastcgi.socket" + var.PID, "max-procs" => 1, "kill-signal" => 9, "idle-timeout" => 10, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "200", "PHP_FCGI_MAX_REQUESTS" => "1000" ), "/pyapps/essai/blondes.fcgi" => ( "main" => ( "socket" => "/var/tmp/lighttpd/django-fastcgi.socket", ), ), "bin-copy-environment" => ( "PATH", "SHELL", "USER" ), "broken-scriptfilename" => "enable" ))) [...] $HTTP["host"] =~ "(^|www\.)cam\.com(\:[0-9]*)?$" { server.document-root = "/home/cam/web/" accesslog.filename = "/home/cam/log/access.log" server.errorlog = "/home/cam/log/error.log" server.follow-symlink = "enable" # files to check for if .../ is requested server.indexfiles = ( "index.php", "index.html", "index.htm", "index.rb") url.rewrite = ( "^(/blondes/.*)$" => "/pyapps/essai/blondes.fcgi$1" ) } I have the following dir tree: /home/tv/web/ `-- pyapps `-- essai `-- __init__.py `-- blondes.fcgi `-- blondes.pid `-- django-fcgi.py `-- manage.py `-- manage.pyo `-- plop `-- settings.py `-- urls.py No error when restarting lighthttpd. The I run: ./manage.py runfcgi method=prefork socket=/var/tmp/lighttpd/django-fastcgi.socket daemonize=false pidfile=blondes.pid No errors neither. I then go to http://cam.com/blondes/. I offers me to download an empty file. I checked permissions but everything is set to the same user and group, and they work for the PHP site. The file /var/tmp/lighttpd/django-fastcgi.socket exists. When I reload the page, I got no output in error logs, nor in the manage.py runfcgi command. I probably missed something obvious, but what ?

  • Apache runs in console but not as a service?

    - by danspants
    I have an apache 2.2 server running Django. We have a network drive T: which we need constant access to within our Django app. When running Apache as a service, we cannot access this drive, as far as any django code is concerned the drive does not exist. If I add... <Directory "t:/"> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> to the httpd.conf file the service no longer runs, but I can start apache as a console and it works fine, Django can find the network drive and all is well. Why is there a difference between the console and the service? Should there be a difference? I have the service using my own log on so in theory it should have the same access as I do. I'm keen to keep it running as a service as it's far less obtrusive when I'm working on the server (unless there's a way to hide the console?). Any help would be most appreciated.

  • Choosing the right .NET architecture. WCF? WPF/Forms, ASP.NET (MVC)?

    - by Tommy Jakobsen
    I’m in the situation that I have to design and implement a rather big system from the bottom. I’m having some (a lot actually) questions about the architecture that I would like your comments and thoughts on. I don’t hope that I’ve written too much here, but I wanted to give you all an idea of what the system is. Quick info about the applications, read if you want: I can’t share much detail about the project, but basically it’s a system where we offer our customer a service to manage their users. We have a hotline where the users call and our hotline uses an (windows) application (intranet) to manage the user’s data, etc. The customer also has a web application where they can see reports, information about their business and users, and the ability to modify their data. Modifying data is not just user data like address and so, but also information about the products/services the user has, which can be complicated. The applications will be built on Microsoft .NET Framework 4, with a MS SQL Server 2008 database. There will be a few applications that have to access this database, such as: Intranet application (used by us and our hotline) Customer web application type 1 Customer web application type 2 Customer web application type n different applications) … Now my big problem is what .NET parts I should use for such a system. For the “backend” I’ve considered using Windows Communication Foundation: Would WCF be a good choice? The intranet application will be an application that has to edit lots of records in the database. It has to be easy to navigate using the keyboard (fast to work with). Has a feature such as “find customer, find that, lookup this, choose this and update that”. What would be the best choice to develop this application in? Would it be WPF or good old Windows Forms? I don’t need all of the fancy graphics features in WPF, like 3D, but the application has to look nice (maybe something like the new Visual Studio/Office tools). And the same question goes for the web pages. They have much the same work to do, but not as many features as the intranet application, and not the same amount of data (much less). That is my questions for now. I’m hoping to get a discussion going that will open my eyes to some of these technologies, helping me decide architecture to go with. I would like to say thanks in advance, and let you all know that any thoughts will be much appreciated.

  • Web Application Problems (web.config errors) HTTP 500.19 with IIS7.5 and ASP.NET v2

    - by Django Reinhardt
    This is driving the whole team crazy. There must be some simple mis-configured part of IIS or our Web Server, but every time we try to run out ASP.NET Web Application on IIS 7.5 we get the following error... Here's the error in full: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. `Detailed Error Information` Module IIS Web Core Notification Unknown Handler Not yet determined Error Code 0x8007000d Config Error Config File \\?\E:\wwwroot\web.config Requested URL http://localhost:80/Default.aspx Physical Path Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: The machine is running Windows Server 2008 R2. We're developing our Web Application using Visual Studio 2008. According to Microsoft the code 8007000d means there's a syntax error in our web.config -- except the project builds and runs fine locally. Looking at the web.config in XML Notepad doesn't bring up any syntax errors, either. I'm assuming it must be some sort of poor configuration on my part...? Does anyone know where I might find further information about the error? Nothing is showing in EventViewer, either :( Not sure what else would be helpful to mention... Assistance is greatly appreciated. Thanks! UPDATES! - POSTED WEB.CONFIG BELOW Ok, since I posted the original question above, I've tracked down the precise lines in the web.config that were causing the error. Here are the lines (they appear between <System.webServer> tags)... <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </httpHandlers> Note: If I delete the lines between the <httpHandlers> I STILL get the error. I literally have to delete <httpHandlers> (and the lines inbetween) to stop getting the above error. Once I've done this I get a new 500.19 error, however. Thankfully, this time IIS actually tells me which bit of the web.config is causing a problem... <handlers> <remove name="WebServiceHandlerFactory-Integrated"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </handlers> Looking at these lines it's clear the problem has migrated further within the same <system.webServer> tag to the <handlers> tag. The new error is also more explicit and specifically complains that it doesn't recognize the attribute "validate" (as seen on the third line above). Removing this attribute then makes it complain that the same line doesn't have the required "name" attribute. Adding this attribute then brings up ASP.NET error... Could not load file or assembly 'System.web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56' or one of its dependencies. The system cannot find the file specified. Obviously I think these new errors have just arisen from me deleting the <httpHandlers> tags in the first place -- they're obviously needed by the application -- so the question remains: Why would these tags kick up an error in IIS in the first place??? Do I need to install something to IIS to make it work with them? Thanks again for any help. WEB.CONFIG Here's the troublesome bits of our web.Config... I hope this helps someone find our problem! <system.Web> <!-- stuff cut out --> <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56" validate="false"/> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </httpModules> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules> <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </modules> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <handlers> <remove name="WebServiceHandlerFactory-Integrated"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </handlers> </system.webServer>

  • jqGrid Export to CSV Missing Column Names

    - by user561557
    I have a jqGrid that works perfectly. It contains a pager button to export the grid to a csv file which works and exports the data. However, I also need to have the column names exported with the data and I can't seem to get that to work. My working code follows. jQuery("#detail").jqGrid('navGrid','#pager2', {height:520,width:500,savekey:[true,13],navkeys:[true,38,40],reloadAfterSubmit:false, jqModal:false, closeOnEscape:true, bottominfo:"Fields marked with () are required"}, // edit options {height:520, width:500,savekey:[true,13],reloadAfterSubmit:false,jqModal:false, closeOnEscape:true,bottominfo:"Fields marked with () are required", closeAfterAdd: true}, // add options {reloadAfterSubmit:false,jqModal:false, closeOnEscape:true}, // del options {closeOnEscape:true}, // search options {height:250,width:500,jqModal:false,closeOnEscape:true}, {view:true} // view options ); // add custom button to export the data to excel jQuery("#detail").jqGrid('navButtonAdd','#pager2',{ caption:"", title:"Export to CSV", onClickButton : function () { exportExcel(); }, position:"last" }); // add custom button to print grid jQuery("#detail").jqGrid('navButtonAdd','#pager2',{ caption:"", title:"Print", buttonicon:"ui-icon-print", onClickButton : function () { jQuery('#detail_table').jqprint({ operaSupport: true }); return false; } }); function exportExcel() { var mya=new Array(); mya=jQuery("#detail").getDataIDs(); // Get All IDs var data=jQuery("#detail").getRowData(mya[0]); // Get First row to get the labels var colNames=new Array(); var ii=0; for (var i in data){colNames[ii++]=i;} // capture col names var html=""; for(i=0;i } html=html+"\\n"; // end of line at the end document.forms[0].method='POST'; document.forms[0].action='ajax/csvExport.php'; // send it to server which will open this contents in excel file document.forms[0].target='_blank'; document.forms[0].csvBuffer.value=html; document.forms[0].submit(); }

  • C# BindingSource.AddingNew is never called?

    - by msfanboy
    Hello, BindingSource.AddingNew is never called when I leave the cell of my datagrid. The DataGrid has as datasource the BindingSource which again has a "List" of "Customer". What does the BindingSource need to create a new Customer object and add it to the underlying ICustomerList ? Of course a interface has no constructor... Thats the Exception I get: System.MissingMethodException: The constcructor for the type "SAT.EnCoDe.Administration.ICustomer" was not found. bei System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) bei System.SecurityUtils.SecureCreateInstance(Type type, Object[] args) bei System.ComponentModel.BindingList1.AddNewCore() bei System.ComponentModel.BindingList1.System.ComponentModel.IBindingList.AddNew() bei System.Windows.Forms.BindingSource.AddNew() bei System.Windows.Forms.CurrencyManager.AddNew() bei DevExpress.Data.CurrencyDataController.OnCurrencyManagerAddNew() bei DevExpress.Data.CurrencyDataController.AddNewRow() bei DevExpress.XtraGrid.Views.Grid.GridView.OnActiveEditor_ValueModified(Object sender, EventArgs e) bei DevExpress.XtraEditors.Repository.RepositoryItem.RaiseModified(EventArgs e) bei DevExpress.XtraEditors.BaseEdit.OnEditValueChanging(ChangingEventArgs e) bei DevExpress.XtraEditors.TextEdit.OnMaskBox_ValueChanged(Object sender, EventArgs e) bei DevExpress.XtraEditors.Mask.MaskBox.RaiseEditTextChanged() bei System.Windows.Forms.TextBoxBase.WmReflectCommand(Message& m) bei DevExpress.XtraEditors.Mask.MaskBox.BaseWndProc(Message& m) bei DevExpress.XtraEditors.Mask.MaskBox.WndProc(Message& m) bei DevExpress.XtraEditors.TextBoxMaskBox.WndProc(Message& msg) bei System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

  • Report viewer in wpf and selection formula

    - by shabi
    I have a WPF application that I would like to present SQL Server Reporting Services sql 2008 reports in. I understand we have to use host widow control and then in report viewer control. I want to use remote processing mode. My code sample is : I have added namespaces: using System.Windows.Forms; using System.Windows.Forms.Integration; using Microsoft.Reporting; using Microsoft.ReportingServices; using Microsoft.Reporting.WinForms; My XAML: xmlns:wfi="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration" xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" xmlns:wfr="clr-namespace:Microsoft.Reporting.WinForms;assembly=Microsoft.ReportViewer.WinForms" Title="ReportHost" Height="300" Width="300"> <Grid> <wfi:WindowsFormsHost Height="100" Margin="39,27,39,0" Name="winFormsHost" VerticalAlignment="Top" > <wfr:ReportViewer x:Name="rptViewer" ProcessingMode="Remote" /> </wfi:WindowsFormsHost> </Grid> Code: rptViewer.ServerReport.ReportServerUrl = new Uri("http://mymachine-:8080/ReportServer_myreports"); rptViewer.ServerReport.ReportPath="/Reports/mytestreport.rdl"; rptViewer.ServerReport.Refresh(); My question is that how how can I set selection formula in microsoft report viewer control [like crystal report]. Or miscroft provided any this else which behave like selection formula in crystal reports. And when I run the code it show only report viewer in host window control but not the report data in window. Please some one provide me all step list, Which I have to fallow to get required result with sample code. Quick response will be appricated.
