Visual Basic Text not displayed during Edit and Continue
Has anyone else noticed that when you are in Edit and continue, the typed text or deleted text do not show until either you move off the line or stop the debug process. It happens most of the time. I did not notice this happening in the Beta. It does it in both express and Prof. The computer is a complete reinstall and format c, so there are no traces of the beta stuff here. It does it on two different computers with two different display drivers. Hi, Larry, No, that’s quite surprising to hear – I haven’t heard of anyone else running into that. Typing into the editor window during debugging should be an iden ...Show All

Visual Basic Dragging the form without using the title bar
I have a problem on my splash screen, i set the borderstyle to none. How can I drag the form without having the title bar. I am using Visual Basic Express Thanks. Forgetting the eccentricity of the toolstrip for a minute, I think you are saying that we set a timer when the mouse enters the form area, at each timer event check the mouse to see it is still over the form, and if it is and the left mouse button is still depressed, then do what Do the SendMessage( Handle, WM_NCLBUTTONDOWN, HTCAPTION, 0) or did you have something else in mind Also, I notice using ReleaseCapture and SendMessage ...Show All

Visual Studio Team System Beta 3 Supported OS List
Per the Team Foundation Installation Guide ( http://www.microsoft.com/downloads/details.aspx FamilyId=E54BF6FF-026B-43A4-ADE4-A690388F310E&displaylang=en ), Windows XP is a supported installation platform. However, when trying to install Beta 3 on Windows XP Pro the installation reports that the prerequisite of Windows Server 2003 has not been met.

The client can be Window 2000, XP or 2003. Sorry for the confusion, but if you want to ...Show All

Visual Basic C# or VB ?
other than familiar syntax is there any reason to use VB instead of C# is the difference only syntax Hi Ever since .NET arrived this question has stirred emotions between those developing in VB and those developing in C# (needlsessly so in my opinion). You often find the usual ramblings that C# is better than VB which I guess stems from when VB classic was an interpreted language against C++ which was a compiled language. Prior to the release of VS 2005 there were things that you could do in C# that you couldn't do in VB such as operator overloading, XML comments (although this can be achieved using third party ...Show All
