• Visual Basic Refresh the Winows OS from within Visual Basic

  I've made some program in Visual Basic 2005 that works with changing files and folders. After I've finished it, the main problem is to refresh the Windows OS.

Could someone help me with this matter A possible solution or maybe an idea how to do that   Thanks,  After I've finished it, the main problem is to refresh the Windows OS. Erm... no.

• .NET Development How to refrence any avalible version of a assembly?

  Hi, we have a problem in our company and we can’t solve it. We have an application that uses the Oracle Data Provider (ODP). But when you move the application to another computer that has a different version of ODP (newer version) installed the application doesn’t work, because it is trying to reference a assembly with a specific version and that does not exists... I was going trough the MSDN and some books, and discover that you can manually redirect assembly with: <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly&g ...Show All

• Visual C++ Floating point stack overflow

  My application works fine in VS2003, but in VS2005, it is producing an overflow of the floating point stack.  This seems like it must be a code generation error in the new compiler.  Has anyone else experienced this problem In the particular case I am looking at, I step through the instruction FLDZ in the disassembly window.  Instead of getting a zero in ST(0), I get 1#IND, and the SF and C1 bits are set in the x87 FPU Status Word.  The first time through this code it works OK, but this second time through, the FPU tags register shows that the stack is full before the FLDZ instruction. We have made a total rede ...Show All

• Visual Studio Express Editions SDK for WinXP x64

  Good day, I have AMD64 processor with winXPPro x64 and tried to download the x86 SDK but it wouldn't install (I thought it would install into the x86 folder).

• Visual Studio Help Integration Wizard does not generate title nodes

  Hi, I'm trying for some time now to create a MSI installer to deploy a Help2 File. For this I'm using the Help Integration Wizard - which seems to work all right. But when I've installed the .MSI and start dexplore I can't find my Help at all(but a filter I configured in Step 3 of the wizard shows up). When I take a look with Namespace.exe(contained in VS SDK) I can see the Namespace created by the installer, but unlike all other, this Namespace does not contain a titles Node - which seems to me to be the problem. Can anyone point me to how this could happen or how to convince the Wizard to properly register my helpfile I've tried s ...Show All

• Windows Forms Event source in event handler delegate?

  Please help me determine the source of the event that triggered it. In a Windows Forms application, webbowser control, HTMLElement's onclick event is handled by a delegate event handler that has been attached to it by the application. The event handler has the usual parms, source As object and e As System.EventArgs but source is Nothing and e is empty. I know I am missing something but I cannot find what that is, although I have searched MSDN thoroughly. Can you help me TIA.

• Visual Studio Tools for Office Charts in VSTO Word

  What is the best way to dynamically create charts in VSTO Word solution. I tried using OWC, but I had to wrap it in UserControl before I could add it to document. Anybody knows as way to add it to the Word document from code behind without wrapping it in UserControl. Or should I use Excell itself Well, you basically have two Office automation choices. Both involve creating an embedded OLE object in the document. You can create an Excel graph object, or an MS Graph object. The first would require Excel to be installed on the machine. The second should be available (assuming MS Graph was installed) even if Ex ...Show All
