  • Unable to debug WCF service in VS2008 after UserNamePasswordValidator fault

    - by lsb
    Hi! I have a WCF service that I secure with a custom UserNamePasswordValidator and Message security running over wsHttpBinding. The release code works great. Unfortunately, when I try to run in debug mode after having previously used invalid credentials (the current credentials ARE valid!) VS2008 displays an annoying dialog box (more on this below). A simplified version of my Validate method from the validator might look like the following: public override void Validate(string userName, string password) { if (password != "ABC123") throw new FaultException("The password is invalid!"); } The client receives a MessageSecurityException with InnerException set to the FaultException I explictly threw. This is workable since my client can display the message text of the original FaultException I wanted the user to see. Unfortunately, in all subsequent service calls VS2008 displays an "Unable to automatically debug..." dialog. The only way I can stop this from happening is to exit VS2008, get back in and connect to my service using correct credentials. I should also add that this occurs even when I create a brand new proxy on each and every call. There's no chance MY channel is faulted when I make a call. Its likely, however, that VS2008 hangs on to the previously faulted channel and tries to use it for debugging purposes. Needless to say, this sucks! The entire reason I'm entering "bad" credentials is to test the "bad-credential" handling. Anyway, if anyone has any ideas as to how I can get around this bug (?!?) I'd be very very appreciative....

  • Dynamics CRM 2011 - WCF error

    - by bigtv
    I am trying to get to grips with MS Dynamics CRM 2011. I have have the beta installed on a VM and things look pretty good - some great new features etc. However I am getting an exception when trying to connect to the new XRMServices (updated 2011 WCF web services) Exception: System.ServiceModel.ServiceActivationException: The service '/organame/XRMServices/2011/Organization.svc' cannot be activated due to an exception during compilation. The exception message is: 'System.ServiceModel.Description.UseRequestHeadersForMetadataAddressBehavior'. This collection only supports one instance of each type. Parameter name: item. ---> System.ArgumentException: The value could not be added to the collection, as the collection already contains an item of the same type: 'System.ServiceModel.Description.UseRequestHeadersForMetadataAddressBehavior'. This collection only supports one instance of each type. Parameter name: item The only reference to this exception I gave found suggests that it is caused by multiple bindings configured in IIS, which in my case I did have, but the problem persists even after removing them. Any suggestions would be appreciated.

  • Code Golf: Code 39 Bar Code

    - by gwell
    The challenge The shortest code by character count to draw an ASCII representation of a Code 39 bar code. Wikipedia article about Code 39: http://en.wikipedia.org/wiki/Code_39 Input The input will be a string of legal characters for Code 39 bar codes. This means 43 characters are valid: 0-9 A-Z (space) and -.$/+%. The * character will not appear in the input as it is used as the start and stop characters. Output Each character encoded in Code 39 bar codes have nine elements, five bars and four spaces. Bars will be represented with # characters, and spaces will be represented with the space character. Three of the nine elements will be wide. The narrow elements will be one character wide, and the wide elements will be three characters wide. A inter-character space of a single space should be added between each character pattern. The pattern should be repeated so that the height of the bar code is eight characters high. The start/stop character * (bWbwBwBwb) would be represented like this: # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # ^ ^ ^^ ^ ^ ^ ^^^ | | || | | | ||| narrow bar -+ | || | | | ||| wide space ---+ || | | | ||| narrow bar -----+| | | | ||| narrow space ------+ | | | ||| wide bar --------+ | | ||| narrow space ----------+ | ||| wide bar ------------+ ||| narrow space --------------+|| narrow bar ---------------+| inter-character space ----------------+ The start and stop character * will need to be output at the start and end of the bar code. No quiet space will need to be included before or after the bar code. No check digit will need to be calculated. Full ASCII Code39 encoding is not required, just the standard 43 characters. No text needs to be printed below the ASCII bar code representation to identify the output contents. The character # can be replaced with another character of higher density if wanted. Using the full block character U+2588, would allow the bar code to actually scan when printed. Test cases Input: ABC Output: # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # Input: 1/3 Output: # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # Input: - $ (minus space dollar) Output: # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # Code count includes input/output (full program).

  • Using QTDesigner with PyQT and Python 2.6

    - by PyNewbie27
    Hi. I'm fairly new to Python and trying to work with the latest versions of QTDesigner, PyQT 4.7 and QT4.7 (I downloaded the whole package from PyQT4.7 website). I can't figure out how to make QTDesigner integrate closely with Python: ie. If I select "Form" View Code in QTDesigners menu, it errors saying "Unable to launch C:/Python26/Lib/site-packages/PyQT4/bin\uic." If I look in that directory there is a pyuic.py but not "uic". From searching online it seems this doesn't exist because it's expecting a C++ install instead of the python version. Is there anyway to make QTDesigner use/call pyuic.py to generate the code, then open an IDE or text editor of my choice to show me the PYTHON code generated by the QTDesigner-PyUIC chain? I'd like Designer to integrate closely with python, so I can make custom slots/signals in Designer while designing, then tweak the python code directly in my IDE later. If it is not possible to code directly inside QTDesigner using python, does that mean I have to hand code my programs entire UI directly in my PythonIDE? Using Designer directly would seemingly be nearly very very nice for a newbie such as myself, since I can see what properties each widget has and visually edit them while still learning the QT syntax without constantly having to use web resources to see what properties each widget should have and helps with boilerplate code generation, and what their defaults are, etc. I've googled and nobody seems to be using QTDesigner and Python in this manner together. It seems most are either handcoding all the QT code in their Python IDE of choice, or have found an obvious/easy method of doing what I want, therefore not really producing up to date tutorials on making this work together. Please enlighten me if you can. Thanks in advance for your time. Please include any suggestions you might have to a newbie trying to use Python with QT and QTDesigner. Thank you.

  • Cannot debug views in MVC2 project, getting "The resource cannot be found" error

    - by schefdev
    I'm running Visual Studio 2008 sp1 on Win7, with MVC2 RTM installed. I created a new MVC2 project using the wizard and am unable to debug specific pages. With webforms and even MVC1, I was able to sit on a View page, hit F5, and then have the integrated web server in VS2008 start on the page I was working on. Very handy for building up app logic. When I try this now I get a "The resource cannot be found" error page. I retried this just now with a stock new MVC2 Web Application project. Here are the steps I took after creating the new project to reproduce: Open up project settings. Under the Web subtab, set the Start Action to "Current Page". Leave all the other settings as is. Open one of the views up (e.g. Account/Register.aspx) Hit F5 to debug the project Note that the browser window which displays shows the error message "The resource cannot be found". The link I saw in my browser for this run was: http://localhost:49471/Views/Account/Register.aspx I did some googling and found suggestions related to ensuring all HTTP server pieces were installed. I double checked and made sure that "HTTP Errors" and "HTTP Redirection" were both installed. If I leave the project setting as it was originally, set to "Specific Page" with nothing in the text box, then routing works and I always get the default home page. I'm hoping this isn't the only option. Thanks!

  • What is the difference between System.Speech.Recognition and Microsoft.Speech.Recognition?

    - by Michael
    There are two similar namespaces and assemblies for speech recognition in .NET. I’m trying to understand the differences and when it is appropriate to use one or the other. There is System.Speech.Recognition from the assembly System.Speech (in System.Speech.dll). System.Speech.dll is a core DLL in the .NET Framework class library 3.0 and later There is also Microsoft.Speech.Recognition from the assembly Microsoft.Speech (in microsoft.speech.dll). Microsoft.Speech.dll is part of the UCMA 2.0 SDK I find the docs confusing and I have the following questions: System.Speech.Recognition says it is for "The Windows Desktop Speech Technology", does this mean it cannot be used on a server OS or cannot be used for high scale applications? The UCMA 2.0 Speech SDK ( http://msdn.microsoft.com/en-us/library/dd266409%28v=office.13%29.aspx ) says that it requires Microsoft Office Communications Server 2007 R2 as a prerequisite. However, I’ve been told at conferences and meetings that if I do not require OCS features like presence and workflow I can use the UCMA 2.0 Speech API without OCS. Is this true? If I’m building a simple recognition app for a server application (say I wanted to automatically transcribe voice mails) and I don’t need features of OCS, what are the differences between the two APIs?

  • SharePoint: Can't Connect to a Configuration Database When Using Configuration Wizard

    - by Denis
    Hello everyone. I wonder if you could help me with the following problem: We have a SharePoint farm consisted of two servers with an NLB (a load balancer), a database server and an index server (4 servers in total). The issues initially appeared when we were trying to change Search settings via Shared services provider and an error was appearing with the message I can’t even remember now. To fix that problem, we decided to restart Search services on the Index server via Central Administration… and the process had stuck with a status “stopping” for several days. We’ve found a few solutions on the forums, but nothing had helped. Then we’ve tried to exclude the Index server from the farm, but yet again, Search services would not stop. However, after a week we’ve noticed that the services finally stopped. That was a prologue. So, after the Search services have finally stopped, we decided to return the Index server back to the farm via the SharePoint Configuration wizard. When we click on a button “Search database instances” (don’t know the exact name in English, we have a Russian version), a correct database name and user are automatically appear in the relevant fields. Then we supply a password for the user and click “next” two times and the configuration begins. Unfortunately, at the second stage we receive the error “Could not connect to a configuration database” with the exception in the log file: “Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.” Now we can’t figure out why the configuration wizard can’t connect to the configuration database. Any suggestions will be really appreciated.

  • Manually iterating over a selection of XML elements (C#, XDocument)

    - by user316117
    What is the “best practice” way of manually iterating (i.e., one at a time with a “next” button) over a set of XElements in my XDocument? Say I select the set of elements I want thusly: var elems = from XElement el in m_xDoc.Descendants() where (el.Name.LocalName.ToString() == "q_a") select el; I can use an IEnumerator to iterate over them, i.e., IEnumerator m_iter; But when I get to the end and I want to wrap around to the beginning if I call Reset() on it, it throws a NotSupportedException. That’s because, as the Microsoft C# 2.0 Specification under chapter 22 "Iterators" says "Note that enumerator objects do not support the IEnumerator.Reset method. Invoking this method causes a System.NotSupportedException to be thrown ." So what IS the right way of doing this? And what if I also want to have bidirectional iteration, i.e., a “back” button, too? Someone on a Microsoft discussion forum said I shouldn’t be using IEnumerable directly anyway. He said there was a way to do what I want with LINQ but I didn’t understand what. Someone else suggested dumping the XElements into a List with ToList(), which I think would work, but I wasn’t sure it was “best practice”. Thanks in advance for any suggestions!

  • Android's EditText is hidden when the virtual keyboard is shown and a SurfaceView is involved

    - by Jan
    I have a simple user interface: an EditText should be located below a SurfaceView. I use a RelativeLayout to arrange these two views. Now, when I tap on the EditText to open the virtual keyboard the SurfaceView slides up but the EditText is hidden and does not show the typed string. To reproduce, use the following layout XML code: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout01" android:layout_height="fill_parent" android:layout_width="fill_parent"> <SurfaceView android:id="@+id/SurfaceView01" android:layout_width="fill_parent" android:layout_height="wrap_content"> </SurfaceView> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentLeft="true" android:layout_alignParentBottom="true" android:selectAllOnFocus="true" android:textStyle="normal" android:singleLine="true"> </EditText> </RelativeLayout> The main Activity class only needs to show the layout. When I start the program and tap the EditText, the virtual keyboard appears but the EditText field is gone. Maybe the RelativeLayout is causing the problems, but I don't know how to reproduce the same layout with another Layout class. Any suggestions are welcome, I really appreciate your help. Thanks. Edit: Here are two screenshots, one showing the EditText at the bottom without virtual keyboard, one with virtual keyboard but with no EditText. It is interesting to note that the SurfaceView and the EditText actually shift upward, the EditText just disappears. BTW this also happens to a button if it is next to the EditText. EditText below a SurfaceView (left); EditText is gone (right)

  • DynamicObject and WCF support

    - by rboarman
    Hi, I was wondering if anyone has had any luck getting a DynamicObject to serialize and work with WCF? Here’s my little test: [DataContract] class MyDynamicObject : DynamicObject { [DataMember] private Dictionary<string, object> _attributes = new Dictionary<string, object>(); public override bool TryGetMember(GetMemberBinder binder, out object result) { string key = binder.Name; result = null; if (_attributes.ContainsKey(key)) result = _attributes[key]; return true; } public override bool TrySetMember(SetMemberBinder binder, object value) { _attributes.Add(binder.Name, value); return true; } } var dy = new MyDynamicObject(); var ser = new DataContractSerializer(typeof(MyDynamicObject)); var mem = new MemoryStream(); ser.WriteObject(mem, dy); The error I get is: System.Runtime.Serialization.InvalidDataContractException was unhandled Message=Type 'ElasticTest1.MyDynamicObject' cannot inherit from a type that is not marked with DataContractAttribute or SerializableAttribute. Consider marking the base type 'System.Dynamic.DynamicObject' with DataContractAttribute or SerializableAttribute, or removing them from the derived type. Any suggestions? Thanks, Rick

  • .NET C#: WebBrowser control Navigate() does not load targeted URL

    - by Dave
    Hey guys, I'm trying to programmatically load a web page via the WebBrowser control with the intent of testing the page & it's JavaScript functions. Basically, I want to compare the HTML & JavaScript run through this control against a known output to ascertain whether there is a problem. However, I'm having trouble simply creating and navigating the WebBrowser control. The code below is intended to load the HtmlDocument into the WebBrowser.Document property: WebBrowser wb = new WebBrowser(); wb.AllowNavigation = true; wb.Navigate("http://www.google.com/"); When examining the web browser's state via Intellisense after Navigate() runs, the WebBrowser.ReadyState is 'Uninitialized', WebBrowser.Document = null, and it overall appears completely unaffected by my call. On a contextual note, I'm running this control outside of a Windows form object: I do not need to load a window or actually look at the page. Requirements dictate the need to simply execute the page's JavaScript and examine the resultant HTML. Any suggestions are greatly appreciated, thanks!

  • Python Image Library, Close method

    - by DNN
    Hello, I have been using pil for the first time today. And I wanted to resize an image assuming it was larger than 800x600 and also create a thumbnail. I could do either of these tasks separately but not together in one method (I am doing a custom save method in django admin). This returns a "cannot identify image file" error message. The error is on the line "image = Image.open(self.photo)" after "#if image is size is greatet than 800 x 600 then resize image." I thought this may be because the image is already open, but if i remove the line I still get issues. So I thought I could try closing after creating a thumbnail and then reopening. But I couldn't find a close method.... This is my code: def save(self): #create thumbnail Thumb_Size = (75, 75) image = Image.open(self.photo) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Thumb_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.thumbnail.save(suf.name+'.jpg', suf, save=False) #if image is size is greatet than 800 x 600 then resize image. image = Image.open(self.photo) if image.size[0] > 800: if image.size[1] > 600: Max_Size = (800, 600) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Max_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.photo.save(suf.name+'.jpg', suf, save=False) #enter info to database super(Photo, self).save()

  • Rails model belongs to model that belongs to model but i want to use another name

    - by Micke
    Hello. This may be a stupid question but im just starting to learn Rail thats why i am asking thsi question. I have one model called "User" which handles all the users in my community. Now i want to add a guestbook to every user. So i created a model called "user_guestbook" and inserted this into the new model: belongs_to :user and this into the user model: has_one :user_guestbook, :as => :guestbook The next thing i did was to add a new model to handle the posts inside the guestbook. I named it "guestbook_posts" and added this code into the new model: belongs_to :user_guestbook And this into the user_guestbook model: has_many :guestbook_posts, :as => :posts What i wanted to achive was to be able to fetch all the posts to a certain user by: @user = User.find(1) puts @user.guestbook.posts But it doesnt work for me. I dont know what i am doing wrong and if there is any easier way to do this please tell me so. Just to note, i have created some migrations for it to as follows: create_user_guestbook: t.integer :user_id create_guestbook_posts: t.integer :guestbook_id t.integer :from_user t.string :post Thanks in advance!

  • Getting the submatrix with maximum sum?

    - by guirgis
    With the help of the Algorithmist and Larry and a modification of Kadane's Algorithm, here is my solution: int dim = matrix.length; //computing the vertical prefix sum for columns int[][] ps = new int[dim][dim]; for (int i = 0; i < dim; i++) { for (int j = 0; j < dim; j++) { if (j == 0) { ps[j][i] = matrix[j][i]; } else { ps[j][i] = matrix[j][i] + ps[j - 1][i]; } } } int maxSoFar = 0; int min , subMatrix; //iterate over the possible combinations applying Kadane's Alg. //int toplefti =0, topleftj=0, bottomrighti=0, bottomrightj=0; for (int i = 0; i < dim; i++) { for (int j = i; j < dim; j++) { min = 0; subMatrix = 0; for (int k = 0; k < dim; k++) { if (i == 0) { subMatrix += ps[j][k]; } else { subMatrix += ps[j][k] - ps[i-1][k]; } if(subMatrix < min){ min = subMatrix; } if((subMatrix - min) > maxSoFar){ maxSoFar = subMatrix - min; } } } } The only problem left is to determine the submatrix elements, i mean the top left and the bottom right corners. I managed to do this in one dimensional case. Any suggestions?

  • Making flexible C# code in MVC2 for Stored Procedures

    - by cc0
    Thanks to Darin Dimitrov's suggestion I got a big step further in understanding good MVC code, but I'm having some problems making it flexible. I implemented Darin's suggested solution, and it works perfectly for single controllers. However I'm having some trouble implementing it with some flexibility. What I'm looking for is this; To be able to make dynamic column names in json Instead of using "Column1: 'value', ..." and "Column2: 'value', ..." inside the json, I'd like to use for example "id: 'value', ..." and "place: 'value' ..." for one stored procedure, and "animal" and "type" in another (inside the json format). To be able to make dynamic amounts of columns dependent on which stored procedure is called Some stored procedures I'll want to read more than 2 rows from, is there a smart way of accomplishing that? To be able to make numeric (floats and integers) rows from the database be presented inside the json without quotes Like this (name and age); { Column1: "John", Column2: 53 }, I would be very grateful for any feedback and suggestions / code examples I can get here. Even imperfect ones.

  • ASP.NET MVC - Html.DropDownList - Value not set via ViewData.Model

    - by chrisb
    Have just started playing with ASP.NET MVC and have stumbled over the following situation. It feels a lot like a bug but if its not, an explanation would be appreciated :) The View contains pretty basic stuff <%=Html.DropDownList("MyList", ViewData["MyListItems"] as SelectList)%> <%=Html.TextBox("MyTextBox")%> When not using a model, the value and selected item are set as expected: //works fine public ActionResult MyAction(){ ViewData["MyListItems"] = new SelectList(items, "Value", "Text"); //items is an ienumerable of {Value="XXX", Text="YYY"} ViewData["MyList"] = "XXX"; //set the selected item to be the one with value 'XXX' ViewData["MyTextBox"] = "ABC"; //sets textbox value to 'ABC' return View(); } But when trying to load via a model, the textbox has the value set as expected, but the dropdown doesnt get a selected item set. //doesnt work public ActionResult MyAction(){ ViewData["MyListItems"] = new SelectList(items, "Value", "Text"); //items is an ienumerable of {Value="XXX", Text="YYY"} var model = new { MyList = "XXX", //set the selected item to be the one with value 'XXX' MyTextBox = "ABC" //sets textbox value to 'ABC' } return View(model); } Any ideas? My current thoughts on it are that perhaps when using a model, we're restricted to setting the selected item on the SelectList constructor instead of using the viewdata (which works fine) and passing the selectlist in with the model - which would have the benefit of cleaning the code up a little - I'm just wondering why this method doesnt work.... Many thanks for any suggestions

  • VSTO Development - Key Improvements In VS2010 / .NET 4.0?

    - by dferraro
    Hi all, I am trying to make a case to my bosses on why we should use VS2010 for an upcoming Excel Workbook VSTO application. I haven't used VSTO before but have used VBA. With 2010 just around the corner, I wanted to read about the improvements made to see if it was worth using 2010 to develop this application. So far I have read 2 major improvements are ease of deployments and also debugging / com interop improvements ... I was just wondering if there was anything else I wasn't aware of, or if anyone here is actually developing in VSTO and has used 2010 and both 2008 and could help make a case / arm me with information. The main concern of my bosses is deploying .NET 4.0 runtime on the Citrix servers here... however it seems that with 3.5, we would have to deploy the VSTO runtime and PIA's, etc... So really wouldn't deployments be easier with 2010 because installing just the 4.0 runtime is better than having to install the 'VSTO Runtime' as well as PIA's, etc? Or is there something I'm missing here? Anyone here deploy VSTO app in an enterprise and can speak to this? Also - I'm trying to also fight to use C# over VB.NET for this app. Does anyone know any key reasons why (except for my bias on preference of syntax) it would be better to use C# over VB for this? Any key features lacking in VB VSTO development? I've read about the VSTO Power Tools, and one of them describes LINQ enalbment of the Excel Object Model classes - however it says 'a set of C# classes'... Does anyone know if they literally mean C# - so this would not work with VB.NET, or do they just mean the code is written in C#? Anyone ever used these power tools with VB? I am going to download & play with it now, but any help again is greatly appreciated Thanks very much for any information.

  • jqGrid local data manipulation; problem with row ids when deleting and adding new rows

    - by Sam
    I'm using jqGrid as a client side grid input, allowing the user to input multiple records before POSTing all the data back at once. I'm having a problem where if the user has added a few records (say 3 ) the id's for the records will be 1,2,3. if the user deletes record 2, you're left with 1 and 3 for the id of the records. When the user now adds a new records, jqGrid assigns that records the id 3 again since it just seems to count the total records and increments it by one for the new record. This causes problems when selecting rows as now the row id's are 1, 3 and 3. Does anyone know how to access the row ids of records as I could probably use the afterSubmit event and reassign the row id's increasing from 1. ( so after i delete row id 2, this will set the other row id's to 1 and 2) Any other suggestions to solve this problem? Thanks edit I've solved this with the following code for the delete navGrid button }).navGrid('#pager', {add:true, del:true, refresh:false, search:false}, { ... }, ##edit parameters { ... }, ##add parameters {reloadAfterSubmit:false, clearAfterAdd:false, afterComplete: function () { ## clear and readd the row data so the row ids are sequential var savedData= $("#inputgrid").jqGrid('getRowData'); $("#inputgrid").jqGrid('clearGridData'); $("#inputgrid").jqGrid('addRowData', 'rn', savedData); } } ##delete parameters ); Basically just saving the grid data and then re-adding it so that the rowids are sequential again. For some reason it causes the row numbers down the left side to go start from 2 instead of one. Edit this was solved by using the latest jqGrid code in GitHub (27th April 2010)

  • What is the equivalent of memset in C#?

    - by Jedidja
    I need to fill a byte[] with a single non-zero value. How can I do this in C# without looping through each byte in the array? Update: The comments seem to have split this into two questions - Is there a Framework method to fill a byte[] that might be akin to memset What is the most efficient way to do it when we are dealing with a very large array? I totally agree that using a simple loop works just fine, as Eric and others have pointed out. The point of the question was to see if I could learn something new about C# :) I think Juliet's method for a Parallel operation should be even faster than a simple loop. Benchmarks: Thanks to Mikael Svenson: http://techmikael.blogspot.com/2009/12/filling-array-with-default-value.html It turns out the simple for loop is the way to go unless you want to use unsafe code. Apologies for not being clearer in my original post. Eric and Mark are both correct in their comments; need to have more focused questions for sure. Thanks for everyone's suggestions and responses.

  • How do I use Fluent NHibernate with .NET 4.0?

    - by Tomas Lycken
    I want to learn to use Fluent NHibernate, and I'm working in VS2010 Beta2, compiling against .NET 4, but I'm experiencing some problems. Summary My main problem (at the moment) is that the namespace FluentNHibernate isn't available even though I've imported all the .dll assemblies mentioned in this guide. This is what I've done: 1. I downloaded the Fluent NHibernate source from here, extracted the .zip and opened the solution in VS. A dialog asked me if I wanted to convert the solution to a VS2010 solution, so I did. 2. I then went into each project's properties and configured all of them to compile for .NET 4, and built the entire solution. 3. I copied all the .dll files from /bin/Debug/ in the FluentNHibernate to a new folder on my local hard drive. 4. In my example project, I referenced FluentNHibernate.dll and NHibernate.dll from the new folder. This is my problem: If I right-click on FluentNHibernate in the References list and select "View in Object Browser...", it shows up correctly. Now, when I try to create a mapping class, I can't import FluentNHibernate. This code: using FluentNHibernate.Mapping; namespace FluentNHExample.Mappings { } generates an error on the using statement, saying The type or namespace 'FluentNHibernate' could not be found (are you missing a using directive or an assembly reference?). The FluentNHibernate assembly is still in the list of References of my project, but if I try to browse the assembly in Object Browser again, it can't be found. What is causing this?

  • OAuth with Google Reader API using Objective C

    - by Dylan
    I'm using the gdata OAuth controllers to get an OAuth token and then signing my requests as instructed. [auth authorizeRequest:myNSURLMutableRequest] It works great for GET requests but POSTs are failing with 401 errors. I knew I wouldn't be able to remain blissfully ignorant of the OAuth magic. The Google Reader API requires parameters in the POST body. OAuth requires those parameters to be encoded in the signature like they were on the query string. It doesn't appear the gdata library does this. I tried hacking it in the same way it handles the query string but no luck. This is so difficult to debug as all I get is a 401 from the Google black box and I'm left to guess. I really want to use OAuth so I don't have to collect login credentials from my users but I'm about to scrap it and go with the simpler cookie based authentication that is more mature. It's possible I'm completely wrong about the reason it's failing. This is my best guess. Any suggestions for getting gdata to work or maybe an alternative iphone friendly OAuth library?

  • Problem hosting WebBrowser control in an ATL app.

    - by Andrew Bucknell
    I have a legacy atl app that hosts a webbrowser control in an ATL window. I create an instance of the client to host the browser using the following sequence CComPtr<IOleObject> spOleObject; HRESULT hr = CoCreateInstance(CLSID_WebBrowser, NULL, CLSCTX_INPROC, ID_IOleObject,(void**)&spOleObject); spOleObject->SetClientSite(this); GetClientRect(&rcClient); hr = spOleObject->DoVerb(OLEIVERB_INPLACEACTIVATE, &msg, this, 0, m_hWnd, &rcClient); hr = AtlAdvise(m_spWebBrowser, GetUnknown(), DIID_DWebBrowserEvents2, &m_dwCookie); CComVariant navvar(navurl); m_spWebBrowser->Navigate2(&navvar, NULL, NULL, NULL, NULL); This sequence works fine to create the initial browse window. The call to navigate2 works and if I look at the window via spy++ I have Shell Embedding - Shell DocObject View - Internet Explorer_Server. When a popup occurs (detected through NewWindow3) I launch a new window and execute the same code sequence for the new window. In the popup window the navigate2 doesnt work, and when I look at this new window in spy++ I just have Shell Embedding. I get the same problem even if I instantiate the popup window on startup, so its not related to NewWindow3 at all - it seems the second instance of the web control isnt instantiating even though all the calls return S_OK. This sequence worked fine under IE7 but now I am using IE8 and the popup window isnt working. There is clearly something I am missing but I cant guess what it may be. Any suggestions would be incredibly helpful.

  • How to use Excel VBA to extract Memo field from Access Database?

    - by the.jxc
    I have an Excel spreadsheet. I am connecting to an Access database via ODBC. Something along then lines of: Set dbEng = CreateObject("DAO.DBEngine.40") Set oWspc = dbEng.CreateWorkspace("ODBCWspc", "", "", dbUseODBC) Set oConn = oWspc.OpenConnection("Connection", , True, "ODBC;DSN=CLIENTDB;") Then I use a query and fetch a result set to get some table data. Set oQuery = oConn.CreateQueryDef("tmpQuery") oQuery.Sql = "SELECT idField, memoField FROM myTable" Set oRs = oQuery.OpenRecordset The problem now arises. My field is a dbMemo because the maximum content length is up to a few hundred chars. It's not that long, and in fact the value I'm reading is only a dozen characters. But Excel just doesn't seem able to handle the Memo field content at all. My code... ActiveCell = oRs.Fields("memoField") ...gives error Run-time error '3146': ODBC--call failed. Any suggestions? Can Excel VBA actually get at memo field data? Or is it just completely impossible. I get exactly the same error from GetChunk as well. ActiveCell = oRs.Fields("memoField").GetChunk(0, 2) ...also gives error Run-time error '3146': ODBC--call failed. Converting to a text field makes everything work fine. However some data is truncated to 255 characters of course, which means that isn't a workable solution.

  • Loading Properties with Spring (via System Properties)

    - by gabe
    My problem is as follows: I have server.properties for different environments. The path to those properties is provided trough a system property called propertyPath. How can I instruct my applicationContext.xml to load the properties with the given propertyPath system property without some ugly MethodInvokingBean which calls System.getProperty(''); My applicationContext.xml <bean id="systemPropertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/> <property name="placeholderPrefix" value="sys{"/> <property name="properties"> <props> <prop key="propertyPath">/default/path/to/server.properties</prop> </props> </property> </bean> <bean id="propertyResource" class="org.springframework.core.io.FileSystemResource" dependency-check="all" depends-on="systemPropertyConfigurer"> <constructor-arg value="sys{propertyPath}"/> </bean> <bean id="serviceProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="location" ref="propertyResource"/> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" ref="propertyResource"/> <property name="placeholderPrefix" value="prop{"/> <property name="ignoreUnresolvablePlaceholders" value="true"/> <property name="ignoreResourceNotFound" value="false"/> </bean> <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="prop{datasource.name}"/> </bean> with this configuration the propertyResource alsways complains about java.io.FileNotFoundException: sys{propertyPath} (The system cannot find the file specified) Any suggestions? ;-) Thanks gabe

  • Getting MSDeploy working on our build/integration server - Is an MSBuild upgrade necessary?

    - by Jeff D
    We have what I think is a fairly standard build process: 1. Developer: Check in code 2. Build: Polls repo, sees change, and kicks off build that: 3. Build: Updates from repo, Builds w/ MSBuild, Runs unit tests w/ nunit, 4. Build: creates installer package Our security team allows us to pull from the build server, but does not allow the build server to push. So we generally rdp in, d/l the installers, and run them, which rules out the slick deployment services, so I would need to generate packages instead. I'd like to use MSDeploy, except that we have the following issues: We're on .net 3.5, and the MSBuild target (Package) that uses MSDeploy requires 4.0. Is there anything I'd need to install other than .net 4.0 RC for this? (Would MSBuild be part of that upgrade?) When I generate packages with MSDeploy, I see that I don't have just 1 file. There's a zip, deploy.cmd, SourceManifest.xml, and SetParameters.xml. What are all the other files for, and why wouldn't they all be in the 'package'? It sounds as if you can create packages by telling the system to look at a working IIS site. But if the packages are build from a CI environment, aren't you basically out of luck here? It feels like they designed some of this for small-scale developers deploying from their dev environment. That's a fine use case, but I'm interested in see what everyone's enterprise-experience is with the tool Any suggestions?
