• Visual Studio Express Editions dynamic textbox with borderstyle none

  Dear all, I created several controls 'on the fly', events and all, fine. But now I Needed a textbox that only showed a border when active, else I wanted the borderstyle to be 'none'. The very next time this control was referenced it lost it's text, and a nasty com-error about a window handler popped up. I guess I'll have to work around it. Can I ask Bill somehow to have his staff look into it Best wishes, J. I think I see what he is talking about. I had a small program handy and added this: Private Sub Form1_Load( ByVal sender As Object , ByVal e As System.EventArgs) Handles Me .Load Me .TextBox2.BorderStyle = System.Windows.Forms.BorderStyle.None End Sub Priva ...Show All

• Software Development for Windows Vista Printer Pipeline Filter Sample

  Where is the sample source "Printer Pipeline Filter Sample - Nup, Booklet, Watermark" of WDK5270 installed I was not able to find it. Nitin, My apologies for the delay in our response.

• Visual Studio Express Editions Please help: Screen text Reader

  Hi, I am in the process of developing an application in VB 2005 that assist with everyday writing skills. The application will focus on helping with spelling, grammar and continuous checking on writing style. The question I wish to ask is this. On my application there are two Rich-Textboxes: one is for displaying the contents of the currect document and the other one displays the sentences that need editing. Also beneath the sentence, I wish display to a suggestion of words that best fits that sentence. And the program will continue to proof-read the document until there are no more writing and structure errors. I wish to know whether anyone out there knows the code for displaying a replica of the document currently us ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. CPU problem

  Does any one know about why CPU is up to 100% when I minimize window Thanks If you don't stop your update/rendering loop when your app goes into background, then your code can start running like crazy because it's not rendering anything, but the update function is executing very fast... Ideally, your app should stop doing any processing when it goes into the background, so you allow other processes in the foreground to work smoothly... ...Show All

• Visual Basic How to Break on All Errors?

  In Visual Basic 6 under the Options...General tab, there is an option to "Break on All Errors". I've been unable to find a similar setting in Visual Studio 2005. Does something similar exist Hi, Michael, The closest you're going to get to that is the dialog which comes up from choosing Debug/Exceptions. It will allow you to set which exceptions you should break on, and under what circumstances (i.e., break on user-unhandled exceptions). By default, I believe we break on all user-unhandled exceptions, and about a dozen exceptions when thrown regardless of handling. The article at http://msdn2.microsoft.com/en-us/library/x85tt0dd.aspx is a bit more specific about exception handling when debuggi ...Show All

• Windows Forms Problem: Can a Form == a Control??

  This is quite an interesting problem (well I think so, but then again, I am a bit strange). I have a .NET 2.0 application that consists of a number of panels that can be dragged around and docked - not unlike the Visual Studio IDE in fact. In these panels I can put any control I care to choose. All well so far. Now then. I have another .NET 2.0 application which fulfils some functional need (as applications tend to do) but it was a bit of a nuisance that it was a separate app. I wanted it to be included as part of my aformentioned panel app. So, after having a look at the object hierarchy for Form, I noticed that it derives from Control. "Yipee!" says I, theoretically I can drop an instance of this entire app as a Contro ...Show All
