• Computer-Desk Object Styles -- System.Windows.Forms vs System.Web.UI.WebControls

  System.Web.UI.WebControls.Button can load a style based on XAML. This can be done by using the Style method. I was wondering if there was a way to apply a XAML Style to a System.Windows.Forms.Button, since there is no Style method; I am unsure on how to do this. System.Windows.Forms.Button is based on Win32 controls which existed well before XAML. You question doesn't apply specifically to the C# language, moving from Visual C# Language to Windows Forms General forum. ...Show All

• mcass Bootstrapper problems

  Hello all, I've been trying to figure out this problem for a while... it should be extremely basic, but I've looked on the MSDN website and in a vb.net book, and still can't find the answer. I've download the .net bootstrapper, but i simply can't figure out (for the life of me) how to use it, or how to change application settings etc. How do i do this! Thanks so much! Sorry for such a dumb question -Robert Are you referring to the VS 2003 bootstrapper here http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnnetdep/html/vsredistdeploy1_1.asp VS 2005 has one built in. ...Show All

• cracklestudios DoEvents in a Class Library

  Hi, I have a VC# dll which has a while(true) loop. I was using a DoEvents in the original code, but now when I write the dll I cant use the DoEvents !! Is there a way to use DoEvents in a Class Library Thanks. Thanks a lot Andreas, I didnt realize I had marked the reply as an answer. And apologies to the rest of the people on the forum for my rudeness in my previous reply. I have two threads, one for sending and the other for receiving the data. I call these threads from a function, and this function is called from my C++ code at the time of initialization.

• Meso X Namespace Error

  In Vis Studio 2005, ASP.NET 3, C# because I had so many form classes in the project, I added a folder and began moving the form classes into the new folder (e:\Work\Asp\WinC\cbiz\Form\). If the form class contained a dataset, this error appeared: Error 2 'thomas.DataSet' is a 'namespace' but is used like a 'type' E:\Work\AspWinC\cbiz\Form\Invoice.cs 17 13 cbiz In the sample snippet below, line 14 was causing this error. Line 15 is a fix, but it makes no sense to me. It seems like line # 4 should cover this.

• CaptainSmudge Toolbar Button Images Not Appearing in Run Mode

  I'm building a simple C# WinForms app that has a toolbar at the top. I've made each of the buttons fairly large: 130 x 32 so that I can include text and an image. The images are being drawn from an ImageList control In Design mode everything looks perfect, but when I run it the images disappear from the buttons! Any ideas why this is happening Robert W. Vancouver, BC Hi Roger, I finally solved the problem by deleting the toolbar and replacing it. But it took several iterations to do so. I now seem to have stable code with regard to this. But I have another frustrating problem: The VERY first time my code is run, the toolbar buttons don't work. Once the app is restarted this NEVER happens again. I think ...Show All

I need a spin control (up down arrows) like in the standard DateTime control as well. I want using msctls_updown32 spin control, 2 static controls for displaying collons and 3 edit controls with custom key down handlers.

Thank you, I will look at it. Are you using System.Windows.Forms to implement your control If not, post in the C++ General forum. Tricky. You are ...Show All

• nithinraj ComponentAdding event: Cancel process of adding component

  Hi everyone, I have a query regarding cancelling the IComponentChangeService.ComponentAdding event. I have an add-in that gets a reference to the IDesignerHost windows, and then hooks into the ComponentAdding event. Inside the ComponentAdding event I sometimes want to be able to cancel the adding of a particular component. According to the MSDN documentation "You can cancel the process of adding a component by throwing an exception here". If I throw an exception inside this event handler, although it does cancel the adding of the control, I get a messagebox in Visual Studio with stack trace info. Although Visual Studio does not close or crash due to this exception, I am wondering if it is possible to somehow cancel the adding ...Show All
