I'm using the SDK that my laptop's touchpad manufacturer, Synaptics, provides in order to extend the touchpad's functionality. In the SDK, there's a file named SynCtrl.dll, which contains a few ActiveX controls.Based on what I learned from the samples provided in the SDK (which are VB 5 old and don't compile), I wrote this little application:

View 3 RepliesI have an application that is primarily developed on an x86 machine. I recently checked the app out of TFS onto a Win 7 x64 machine for development. However, every single form level resource file shows up in the error list with an entry like the following:
is not a valid Win32 application. (Exception from HRESULT: 0x800700C1) Line 127, position 5. C:Users...shortened...FormsfrmCustomer.resx Line 127 Column 5
What I find interesting is that my application level resource files aren't showing the same error. Plus, these are just XML files. They aren't applications in any way.
I'm currently working under VB2010 beta 2 on both machines. Obviously, with a bunch of errors, the app won't compile on the x64 machine.
I was scripting a very basic process manager, with a ListView component, and it was working fine for many days, up until now.Here is the code for getting processes:

win32 handle that was passed to icon is not valid or is the wrong type.

View 2 RepliesI develop windows applications in VB.NET using Visual Studio 2008. Recently I reloaded my pc and moved from XP to Windows 7 64 bit. Now when I am debugging, when I should get a runtime error, the executable instead locks up when it should bring up the code with the line that it crashed on like you'd expect in debug.
This doesn't happen all the time, only when I get a runtime error in a separate assembly that is not in the assembly I'm debugging. It used to work fine, but now it locks up. If I run the executable outside of Visual Studio (without debug) I at least get a runtime error like you'd hope for. I don't even get that when debugging.

I've started a project in Expression Blend and has been working the codes in Visual Studio 2008. It was alright, no problem. I've worked heaps of projects like that before without any problems. However, out of nowhere, my WPF designer in VS2008 now gives me the following error:
Object reference not set to an instance of an object.
at MS.Internal.Package.VSIsolationProviderService.CreateIsolationProvider(String identity, AssemblyReferenceProvider assemblyReferences, IEnumerable'1 assemblyFolders)
at MS.Internal.Providers.VSDesignerContext.GetIsolationProvider(IServiceProvider provider, [Code] .....
It displays the above instead of displaying the WPF designer. Also, I cannot Debug>Start Debugging the application anymore. I can still run/test/build it in Expression studio though. The funny thing is that if I restart a project in Expression blend, copy all the xaml codes, and copy all the vb .net codes from the original application, it works for some time, and then afterwards start giving me the same error at wpf designer in VS2008.

I have an application that starts one of two external CAD applications depending upon the extension of a file in a ListView. I have been able to start up the application to view the file selected without a problem. I also have a seperate print click event for printing the file that opens the viewer application in the background and prints the file. This works perfectly for one of the CAD viewers but when I select a file that requires the other viewer application to print I get a Win32 exception and an error message stating that the file is not associated with any application and it cannot be opened. This of course is rediculous as it opens fine in the "View File" click event that opens the viewer to check the drawing.
One rather strange observation is that the CAD viewer that does print the associated file will launch the other CAD viewer application (that is associated with the other file extensions) when the "View" click event is handled even though I had not incuded the code to execute the process to start the viewer for that type of file. I realize this rather convoluted and may lie in the ProcessStartInfo arguments that I pass to the application.
Here's a code snippet:
Private Sub PrintFinGoods_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintFinGoods.Click
Dim message As String = "No application is associated with file"
