  • Problem with UIScrollView

    - by leon
    Hi, Sorry for long winded post. I am trying to understand UIScrollView and running into very simple problem. I am creating a scroll view I am making this view 1.5 size larger then normal size Using UIScrollView I expect to see some edge elements of view out of bounds, but should be able to pan the view therefore bringing missing elements back to the visible area. However I am seeing that I can't just pan/scroll view anyway I want, instead view always wants to scroll up, as soon as move away my finger from the screen (touch end event). I am not handling any touches, etc - I just want to understand why does not scaled view stay put where I scroll it? CGRect viewFrame = self.view.frame ; viewFrame.size.width *= 1.5; viewFrame.size.height *= 1.5; CGSize mySize = viewFrame.size; [ ((UIScrollView *) self.view) setContentSize: mySize]; self.view.transform = CGAffineTransformMakeScale(1.5, 1.5); What I really trying to accomplish is something similar to Number on iPad (the same code will work on iPhone): There is a view with lots of controls on it (order entry form) User can zoom into the entire form so all elements look bigger user can pan the form therefore bringing various elements into the visible area of the screen. It seems that UIScrollView can should be able to handle zoom and pan actions (for now I am using Affine Transform to zoom in to the order entry form and iPad) Thanks

  • Modified jQuery innerfade sluggish

    - by Jay Hankins
    HI. I am using the jQuery innerfade plugin to scroll through some images on my site. Innerfade is sluggish to move on Firefox 3.6.3, and IE 8. IE 8 is much worse than Firefox, and Chrome runs smoothly. Can you analyze my code to see what the problem is? I've used the modified innerfade from here: http://www.stylephp.com/2009/01/17/customizing-jquery-innerfade-plug-in-adding-controls-navigation-and-caption/ My sites are here: Without bg image: http://dl.dropbox.com/u/145908/doozie2/index.html With bg image: http://dl.dropbox.com/u/145908/doozie2/index2.html Removing my background image fixes the situation; it's not that big of a file. I don't understand why that is an issue. I am using a technique to resize the image to fit the browser window, as you can see in the CSS. Thanks so much. P.S. Sorry, I'm a new user so I can't post more than one link. Please copy and paste the address between <.

  • Strange behavior due to wx.Frame.SetTitle

    - by Anurag Uniyal
    In a wxPython application, which i am porting to Mac OSX, I set title of app frame every 500msec in update UI event, and due to that all the panels and windows are refreshed. That seems strange to me and almost halts my application which has many custom drawn controls and screens. I wanted to know what could be the reason behind it, is it normal for MAC? Here is a self-constrained script which replicates the scenario using timers. It keeps on printing "on paint" every 500ms because in timer I set title every 500ms. import wx app = wx.PySimpleApp() frame = wx.Frame(None, title="BasePainter Test") painter = wx.Panel(frame) def onPaint(event): dc = wx.PaintDC(painter) print "onPaint" painter.Bind(wx.EVT_PAINT, onPaint) def loop(): frame.SetTitle(frame.GetTitle()) wx.CallLater(500, loop) loop() frame.Show(True) app.SetTopWindow(frame) app.MainLoop() My system details: >>> sys.version '2.5 (r25:51918, Sep 19 2006, 08:49:13) \n[GCC 4.0.1 (Apple Computer, Inc. build 5341)]' >>> wx.VERSION (2, 8, 10, 1, '') >>> os.uname() ('Darwin', 'agyeys-mac-mini.local', '9.8.0', 'Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386', 'i386')

  • TinyMCE Image Alignment

    - by will.earp.co.uk
    TinyMCE has always been a little difficult to align images. Either the align tag, or adding style="float: left;" has been it solution. Ideally I would just like to add class="left" or class="right" so that I can set the border and margins of the image. Up until now the only way to do this without using the advimage plugin was to insert the image, then select it, the select a style from the style menu. Ideally I should be able to use the align control in the image dialogue to set the alignment class or use the alignment controls on the toolbar when in the main editing window. I have just again started looking at a solution to this, now that IE6 is finally starting to die, I can use CSS attributes in selectors, so IMG[style="float: left;"] {} Works, but I would rather use a class incase there are any other style attributes which will cause the selector to fail. And it doesn't work in IE6, and you know some corporate clients will still be running the bloody thing! So I looked through the TinyMCE documentation and found the formats configuration option, that seems to allow you to specify how tinyMCE applies code for various operations. Here I can add the IMG tag as a selector, and have classes: "left" for the alignleft function. This applies the class correctly when the alignment is selected from the toolbar, but it still writes an inline style when the alignment is selected through the image dialogue. Am I doing something wrong or is there a better way of doing this that will allow my clients to select image alignment from both the image dialogue and the toolbar, whilst applying a class to the image?

  • WPF data validation is overriding theme on the interface

    - by black sensei
    Hello! Good People I built a WPF application and manage to get the validation working thanks to posts on stackoverflow.The only probblem i'm having is that it's overriding the theme i'm using. example the theme makes the textboxes look like a round rectangle but after setting the binding it look like the default textboxes. here is my code : <Button.Style> <Style TargetType="{x:Type Button}"> <Setter Property="IsEnabled" Value="false" /> <Style.Triggers> <!-- Require the controls to be valid in order to press OK --> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding ElementName=txtEmail, Path=(Validation.HasError)}" Value="false" /> </MultiDataTrigger.Conditions> <Setter Property="IsEnabled" Value="true" /> </MultiDataTrigger> </Style.Triggers> </Style> </Button.Style> code behind is : //Form loaded event code txtEmail.GetBindingExpression(TextBox.TextProperty).UpdateSource(); I've tried to look into the theme file but i was quickly lost.i thought i could use that file like a web css file.Now i've disabled the data binding because of that.Is there any work around for this? thanks for reading this

  • Conditional required field validation in an ASP.net ListView

    - by Jim Dagg
    I'm having a heck of a time trying to figure out how to implement validation in a ListView. The goal is to require the user to enter text in the comments TextBox, but only if the CheckBox is checked. Downside is that these controls are in the EditTemplate of a ListView. Below is a snippet of the relevant code portion of the EditTemplate: <tr style="background-color: #00CCCC; color: #000000"> <td> Assume Risk? <asp:CheckBox ID="chkWaive" runat="server" Checked='<%# Bind("Waive") %>' /> </td> <td colspan="5"> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Comments required" ControlToValidate="txtComments" /> <asp:TextBox Width="95%" ID="txtComments" runat="server" Text='<%# Eval("Comment") %>'></asp:TextBox> </td> <td> <asp:Button ID="btnSave" runat="server" Text="Save" CommandName="Update" Width="100px" /> </td> </tr> Is there a way to do conditional validation using this method? If not, is there a way I could validate manually in the ItemUpdating event of the Listview, or somewhere else, and on a failure, alert the user of the error via a label or popup alert?

  • XAML ContextMenu gets bound to wrong row in a DataGrid

    - by Simon_Weaver
    I have a XAML based ContextMenu bound to the rows in a datagrid. It works just fine - until the grid is scrolled! This is the context menu for one of the controls in the visual tree or a DataGrid row. <data:DataGridTemplateColumn Header="Customer Details" Width="*"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Grid Background="Transparent"> <!-- allows click in entire cell --> <controlsInputToolkit:ContextMenuService.ContextMenu> <controlsInputToolkit:ContextMenu> <controlsInputToolkit:MenuItem Header="{Binding CompletedOrderId,StringFormat='Create Reminder for order #\{0\}'}" CommandParameter="{Binding}"> <controlsInputToolkit:MenuItem.Command> <command:CreateReminderCommand/> </controlsInputToolkit:MenuItem.Command> <controlsInputToolkit:MenuItem.Icon> <Viewbox> <Image Width="19" Height="18" Source="../images/reminders.png" VerticalAlignment="Center"/> </Viewbox> </controlsInputToolkit:MenuItem.Icon> </controlsInputToolkit:MenuItem> <controlsInputToolkit:ContextMenu> <controlsInputToolkit:ContextMenuService.ContextMenu> ...... The ICommand is CreateReminderCommand and the CommandParameter is bound to the data item for the row itself. This works just fine - I can right click on a row and it will show me the correct text in the menu item 'Create Reminder for order 12345'. Then I scroll the datagrid down a page. If I keep right clicking on items then suddenly I'll see the wrong order number for a row. I think what must be happening is this : The DataGrid is reusing instances of MenuItem that it has previously created. How can I force a refresh of the ContextMenu when it is displayed for an item that changes? There's no 'Update method on the ContextMenu or ContextMenuService.

  • Frame Accurate Browser Launchable Video Player ... ?

    - by cliftonc
    I have a requirement where I need to enable playback (full screen) of a h.264 MPEG4 (thanks for the correction!) video from a local network, launchable from a browser link on a Windows workstation, and be frame accurate. By frame accurate I mean that I need to be able to scrub through the video in the same way you would with a vtr, stop at a frame, and then move backwards and forwards frame by frame (it is for a very specific compliance requirement where have to be able to check every frame if there is something that is potentially against broadcasting guidelines). The application itself is used to capture notes while viewing the material, so the end model is for a dual monitor workstation, with a web form in one, the video playing full screen in the second (no issue launching the video and manually having to move it to the second screen), and then the user controls the video via keyboard shortcuts or a jog shuttle. I have looked at QT, but the java bindings seem to be dead or nearly so, flash isn't frame accurate, VLC given its streaming heritage seems to be only able to move forward by a frame and not backwards, and all I have left are commercial offerings that in my experience are difficult and expensive to change. Any ideas of where I should look or alternative options? Any advice appreciated!

  • ASP.Net User Control Template Instantiation

    - by Chris
    Hi, I created a user control that has a template container. <cc:SearchResultItem ID="SearchResultItem1" Customer='<%# ((Customer)(((RepeaterItem)Container).DataItem)) %>' runat="server"> <NameTemplate> <%# Container.Name %> </NameTemplate> </cc:SearchResultItem> This is control is placed in a repeater which lists some customers. The customer is than bound to the user control. When the name template is instantiated in the container, the customer object is not yet available, but I need to access its name because it needs to get parsed before. protected void Page_Init(object sender, EventArgs e) { if (nameTemplate != null ) { // customer is null here, it is avaiable only after Page_Init... NameContainer container = new NameContainer(customer.Id, Parse(customer.Name)); nameTemplate.InstantiateIn(container); placeHolder.Controls.Add(container); } } Question: How can I access properties set for the user control BEFORE the template container is instantiated? Thanks in advance!

  • Publishing to live website

    - by Alienfluid
    Hey there, My friend and I are collaborating on a ASP.NET powered website. To develop it locally, we use Visual Web Developer Express (good enough for our needs). Subversion (using Tortoise SVN) is our source control of choice with the repository residing on Unfuddle.com. We run into problems when we need to update the live site - since there's no version control on it. Currently we use the "Copy to Website" feature in VWD which copies the files using FTP. Here are some problems: VWD only keeps track of files uploaded by one user, so if the other user uploads a newer version of a file to the live site, VWD on my side cannot tell whether the live version of the file is newer or mine is. There's no way to tell whether all the latest changes are available on the live site. We have to be careful not to party all over the shared web.config file since the other user's local DB settings are different from mine, and of course, the live DB settings are a whole other story! What do you guys use to publish to a live site? Does anything out there tie into Subversion so that we can automate the process and always guarantee that the live site is synced to a change list number? Also, how do you manage the different web.config file settings? Thanks!

  • Why user control with code behind file doesn't want to compile under MVC2?

    - by kyrisu
    I have user control in my MVC2 app placed in the Content folder (it's not supposed to be a view, just reusable part of the app). UserControl1.ascx looks like: <@ Control AutoEventWireup="true" Language="C#" CodeFile="~/Content/UserControl1.ascx.cs" Inherits="MVCDrill.Content.UserControl1" %> <div runat="server" id="mydiv"> <asp:LinkButton id="lb_text" runat="server"></asp:LinkButton> </div> UserControl1.ascx.cs looks like: using System; using System.Web; using System.Web.UI; namespace MVCDrill.Content { public class UserControl1 : UserControl { public string Text { get { return this.lb_text.Text; } set { this.lb_text.Text = value; } } } } I'm pretty sure this kind of stuff compiled under webforms but I'm getting compilation error: 'MVCDrill.Content.UserControl1' does not contain a definition for 'lb_text' and no extension method 'lb_text' accepting a first argument of type 'MVCDrill.Content.UserControl1' could be found (are you missing a using directive or an assembly reference?) Am I missing something? How to change it (what is the alternative) in MVC2 ? p.s. Intellisense sees lb_text with no problem. I've tried with different controls with the same outcome.

  • Reporting System architecture for better performance

    - by pauloya
    Hi, We have a product that runs Sql Server Express 2005 and uses mainly ASP.NET. The database has around 200 tables, with a few (4 or 5) that can grow from 300 to 5000 rows per day and keep a history of 5 years, so they can grow to have 10 million rows. We have built a reporting platform, that allows customers to build reports based on templates, fields and filters. We face performance problems almost since the beginning, we try to keep reports display under 10 seconds but some of them go up to 25 seconds (specially on those customers with long history). We keep checking indexes and trying to improve the queries but we get the feeling that there's only so much we can do. Off course the fact that the queries are generated dynamically doesn't help with the optimization. We also added a few tables that keep redundant data, but then we have the added problem of maintaining this data up to date, and also Sql Express has a limit on the size of databases. We are now facing a point where we have to decide if we want to give up real time reports, or maybe cut the history to be able to have better performance. I would like to ask what is the recommended approach for this kind of systems. Also, should we start looking for third party tools/platforms? I know OLAP can be an option but can we make it work on Sql Server Express, or at least with a license that is cheap enough to distribute to thousands of deployments? Thanks

  • Subversion versus Vault

    - by WebDude
    I'm currently reviewing the benefits of moving from SVN to a SourceGear Vault. Has anyone got advice or a link to a detailed comparison between the two? Bear in mind I would have to move my current Source Control system across which works strongly in SVN's favor Here is some info I have found out thus far from my own investigations. I have been taking some time tests between the two and vault seems to perform most operations much faster. Time tests used the same server as the repository, the same workstation client, and the same project. Time Comparisons SVN Add/Commit    12:30 Get Latest Revision    5:35 Tagging/Labelling    0:01 Branching    N/A - I don't think true branching exists in SVN Vault Add/Commit    4:45 Get Latest Revision    0:51 Tagging/Labelling    0:30 Branching    3:23 (can't get this to format correctly) I also found an online source comparing some other points. This is the kind of information i'm looking for. Usage Comparisons Subversion is edit/merge/commit only. Vault allows you to do either edit/merge/commit or checkout/edit/checkin. Vault looks and acts just like VSS, which makes the learning curve effectively zero for VSS users. Vault has a VS plugin, but it only works if you're going to run in checkout-mode. Subversion has clients for pretty much every OS you can imagine; Vault has a GUI client for Windows and a command line client for Mono. Both will support remote work, since both use HTTP as their transport (Subversion uses extended DAV, Vault uses SOAP). Subversion installation, especially w/ Apache, is more complex. Subversion has a lot of third party support. Vault has just a few things. My question Has anyone got advice or a link to a detailed comparison between the two?

  • Java Robot key activity seems to stop working while certain software is running

    - by Mike Turley
    I'm writing a Java application to automate character actions in an online game overnight (specifically, it catches fish in Final Fantasy XI). The app makes heavy use of java's Robot class both for emulating user keyboard input and for detecting color changes on certain parts of the screen. It also uses multithreading and a swing GUI. The application seems to work perfectly when I test it without the game running, just using screenshots to trigger the apps responses into notepad. But for some reason, when I actually launch FFXI and start the program, all of my keyboard and mouse manipulations just stop working altogether. The program is still running, and the Robot class is still able to read pixel colors. But Robot.keyPress, Robot.keyRelease, Robot.mouseMove, Robot.mousePress and Robot.mouseRelease all do nothing. It's the strangest thing-- to test it, I wrote a simple loop that just keeps typing letters, and focused notepad. I'd then start the game, refocus notepad, and it would do nothing. Then I'd exit the game, and it'd start working again immediately. Has anyone else come across something like this, where specific software will stop certain functions of java from working? Also, to make this more interesting-- Last year I wrote a very similar program using the same classes and programming techniques to automate healing a party in the game as they fight. Last year, this program worked perfectly. After running into these problems I dug up that old program, ran it without making any changes, and found that it too was having the same problems. The only differences between now and when it was working: I was running Windows Vista and now I'm running Windows 7, and several new Java versions as well as FFXI versions have been released. What the hell is going on? (if anyone needs to see my source code, email me at [email protected]. I'm trying to keep it to myself.)

  • Keyword 'this'(Me) is not available calling the base constructor

    - by serhio
    In the inherited class I use the base constructor, but can't use class's members calling this base constructor. In this example I have a PicturedLabel that knows it's own color and has a image. A TypedLabel : PictureLabel knows it's type but uses the base color. The (base)image that uses TypedLabel should be colored with the (base)color, however, I can't obtain this color: Error: Keyword 'this' is not available in the current context A workaround? /// base class public class PicturedLabel : Label { PictureBox pb = new PictureBox(); public Color LabelColor; public PicturedLabel() { // initialised here in a specific way LabelColor = Color.Red; } public PicturedLabel(Image img) : base() { pb.Image = img; this.Controls.Add(pb); } } public enum LabelType { A, B } /// derived class public class TypedLabel : PicturedLabel { public TypedLabel(LabelType type) : base(GetImageFromType(type, this.LabelColor)) //Error: Keyword 'this' is not available in the current context { } public static Image GetImageFromType(LabelType type, Color c) { Image result = new Bitmap(10, 10); Rectangle rec = new Rectangle(0, 0, 10, 10); Pen pen = new Pen(c); Graphics g = Graphics.FromImage(result); switch (type) { case LabelType.A: g.DrawRectangle(pen, rec); break; case LabelType.B: g.DrawEllipse(pen, rec); break; } return result; } }

  • Why would javascript click-areas not be working in IE8?

    - by Edward Tanguay
    I'm trying to find a bug in an old ASP.NET application which causes IE8 to not be able to click on the following "button" area in our application: <td width="150px" class="ctl00_CP1_UiCommandManager1i toolBarItem" valign="middle" onmouseout="onMouseOverCommand(this,1,'ctl00_CP1_UiCommandManager1',0,0);" onmouseover="onMouseOverCommand(this,0,'ctl00_CP1_UiCommandManager1',0,0);" onmousedown="onMouseDownCommand(this, 'ctl00_CP1_UiCommandManager1', 0, 0);" onmouseup="onMouseUpCommand(this, 'ctl00_CP1_UiCommandManager1', 0, 0);" id="ctl00_CP1_UiCommandManager1_0_0"> <span style="width:100%;overflow:hidden;text-overflow:ellipsis;vertical-align:middle;white-space:nowrap;"> NEW </span> </td> When we switch IE8 to IE7 compatibility mode, the problem disappears, IE7 is able to click on it. Since the above HTML is generated by a third party control (Janus, http://www.janusys.com/controls), we don't have the source code. has anyone experienced any similar problems with IE8? I've determined that it actually fires the onMouseDownCommand command also the CSS of the button area is different in IE8, it doesn't have color shading that it does in IE7. I can imagine that somewhere the HTML is not valid and IE8 being stricter is not playing along, but where? any advice on how to narrow in on this bug welcome ANSWER: Turned out to be that the application was not checking the navigator.agent for "MSIE 8.0" and was thus treating IE8 has a non-Internet-Explorer browser. Thanks Lazarus for the tip, the IE8 Javascript debugger is very nice, like a Firebug for IE, will be using it more!

  • Asynchronous daemon processing / ORM interaction with Django

    - by perrierism
    I'm looking for a way to do asynchronous data processing with a daemon that uses Django ORM. However, the ORM isn't thread-safe; it's not thread-safe to try to retrieve / modify django objects from within threads. So I'm wondering what the correct way to achieve asynchrony is? Basically what I need to accomplish is taking a list of users in the db, querying a third party api and then making updates to user-profile rows for those users. As a daemon or background process. Doing this in series per user is easy, but it takes too long to be at all scalable. If the daemon is retrieving and updating the users through the ORM, how do I achieve processing 10-20 users at a time? I would use a standard threading / queue system for this but you can't thread interactions like models.User.objects.get(id=foo) ... Django itself is an asynchronous processing system which makes asynchronous ORM calls(?) for each request, so there should be a way to do it? I haven't found anything in the documentation so far. Cheers

  • Forking in PHP on Windows

    - by Doug Kavendek
    We are running PHP on a Windows server (a source of many problems indeed, but migrating is not an option currently). There are a few points where a user-initiated action will need to kick off a few things that take a while and about which the user doesn't need to know if they succeed or fail, such as sending off an email or making sure some third-party accounts are updated. If I could just fork with pcntl_fork(), this would be very simple, but the PCNTL functions are not available in Windows. It seems the closest I can get is to do something of this nature: exec( 'php-cgi.exe somescript.php' ); However, this would be far more complicated. The actions I need to kick off rely on a lot of context that already will exist in the running process; to use the above example, I'd need to figure out the essential data and supply it to the new script in some way. If I could fork, it'd just be a matter of letting the parent process return early, leaving the child to work on a few more things. I've found a few people talking about their own work in getting various PCNTL functions compiled on Windows, but none seemed to have anything available (broken links, etc). Despite this question having practically the same name as mine, it seems the problem was more execution timeout than needing to fork. So, is my best option to just refactor a bit to deal with calling php-cgi, or are there other options? Edit: It seems exec() won't work for this, at least not without me figuring some other aspect of it, as it waits until the call returns. I figured I could use START, sort of like exec( 'start php-cgi.exe somescript.php' );, but it still waits until the other script finishes.

  • Graph limitations - Should I use Decorator?

    - by Nick Wiggill
    I have a functional AdjacencyListGraph class that adheres to a defined interface GraphStructure. In order to layer limitations on this (eg. acyclic, non-null, unique vertex data etc.), I can see two possible routes, each making use of the GraphStructure interface: Create a single class ("ControlledGraph") that has a set of bitflags specifying various possible limitations. Handle all limitations in this class. Update the class if new limitation requirements become apparent. Use the decorator pattern (DI, essentially) to create a separate class implementation for each individual limitation that a client class may wish to use. The benefit here is that we are adhering to the Single Responsibility Principle. I would lean toward the latter, but by Jove!, I hate the decorator Pattern. It is the epitome of clutter, IMO. Truthfully it all depends on how many decorators might be applied in the worst case -- in mine so far, the count is seven (the number of discrete limitations I've recognised at this stage). The other problem with decorator is that I'm going to have to do interface method wrapping in every... single... decorator class. Bah. Which would you go for, if either? Or, if you can suggest some more elegant solution, that would be welcome. EDIT: It occurs to me that using the proposed ControlledGraph class with the strategy pattern may help here... some sort of template method / functors setup, with individual bits applying separate controls in the various graph-canonical interface methods. Or am I losing the plot?

  • Problem with authentication from different domains using Django sessions.

    - by Greg
    Hi all, I am developing a bookmarklet which essentially adds a toolbar to a web page user is currently looking at. To use it, user needs to be logged in. To login user clicks on 'Singin' which displays a standard form containing Username, Password etc fields. When user successfully logs in they may chose to navigate to a different web-site. When on another page, they (a) re-load the bookmarklet (b) their session is retrieved from the server (c) user doesn't need to login again. Pretty standard I've would have thought. Using Django sessions and JQuery. I'm having troubles implementing the above usecase. Here are some problems I've encountered: Cross domain POST AJAX requests are disallowed. That was solved with JSONp. I doubt it is a very secure approach but for now it works. My server returns the session id in a cookie, however when the user navigates to a different page I don't really know how to retrieve that session id to send back to my server. Can I even read third party cookies from my JavaScript? I'm looking for some guidelines on implementing the above usecase. Ideally I don't want to redirect user to another page for them to sign in. Any suggestion would be greatly appreciated. Thanks.

  • Silverlight: how to use a scroll viewer to wrap a list view without specifying height?

    - by John Nicholas
    I have a control that has a list that varies in length greatly. This control appears in various places meaning that i cannot calculate its position and desired height easily. Moreover all I want is for the scrollviewer to simply size itself according to its parent. currently it insists on sizing itself according to the content. currently when i have a list that exceeds the height of the screen the whole control extends off the bottom and the scrollviewer shows no bar (because it has stretched to the heigth of the contents and so thinks it is not required). I've not included code as the object graph is fairly deep. What i am looking for is a set of conditions that would cause the scrollviewer to resize itself according to its content rather than its parent. I have it working in a similar situation involving grids and datagrids, the unique part of this control is that there is a list containing controls. Any ideas? I would prefer solutions that don't require use of code behind - but im really not in a position to be choosey.

  • How do I pass arguments to pages in a WPF application?

    - by Rod
    I'm working on upgrading a really old VB6 app to a WPF application. This will be a page-based app, but not a XBAP. The old VB6 app had a start form where a user would enter search criteria. Then they would get results in a grid, select a row in the grid and then click on one of 3 buttons. I am thinking that what I'll do is use hyperlink controls on the WPF app. No matter what button the user clicked on the old VB6 app, it would go to a second form. What it did on the second form was dependent upon which button the user clicked on the first form. So, I want the first page in my WPF app to do the same thing, but depending upon which hyperlink they click on will dictate what happens on the second page. They will either (a) go to the second page to edit the details as well as a lot more information, related to what they selected on the first page, or (b) enter a new record and all associated data (a new client, in this case), or (c) create a new case for the same client, selected on the first page. For me the hard thing is I don't know how to pass that information along to the second page. Is there something in WPF like in HTML where there's a query string? Or how do you get information from the first page to the second page, in WPF? I'm working in VS 2008.

  • RegularExpression Validator doesn't display error message.

    - by Rudi Ramey
    I have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here? <asp:TextBox ID="txtActualCost" runat="server" Width="120px" CausesValidation="true"></asp:TextBox> <asp:RegularExpressionValidator ID="regExValActualCost" ControlToValidate="txtActualCost" Text="*" ValidationExpression="^\$?(\d{1,3}(\,\d{3})*|(\d+))(\.\d{2})?$" ErrorMessage="Please enter a valid currency value for 'Actual Cost'" Display="Dynamic" EnableClientScript="true" runat="server" />

  • Autodetect Presence of CSV Headers in a File

    - by banzaimonkey
    Short question: How do I automatically detect whether a CSV file has headers in the first row? Details: I've written a small CSV parsing engine that places the data into an object that I can access as (approximately) an in-memory database. The original code was written to parse third-party CSV with a predictable format, but I'd like to be able to use this code more generally. I'm trying to figure out a reliable way to automatically detect the presence of CSV headers, so the script can decide whether to use the first row of the CSV file as keys / column names or start parsing data immediately. Since all I need is a boolean test, I could easily specify an argument after inspecting the CSV file myself, but I'd rather not have to (go go automation). I imagine I'd have to parse the first 3 to ? rows of the CSV file and look for a pattern of some sort to compare against the headers. I'm having nightmares of three particularly bad cases in which: The headers include numeric data for some reason The first few rows (or large portions of the CSV) are null There headers and data look too similar to tell them apart If I can get a "best guess" and have the parser fail with an error or spit out a warning if it can't decide, that's OK. If this is something that's going to be tremendously expensive in terms of time or computation (and take more time than it's supposed to save me) I'll happily scrap the idea and go back to working on "important things". I'm working with PHP, but this strikes me as more of an algorithmic / computational question than something that's implementation-specific. If there's a simple algorithm I can use, great. If you can point me to some relevant theory / discussion, that'd be great, too. If there's a giant library that does natural language processing or 300 different kinds of parsing, I'm not interested.
