However ZoomText has a bug that prevents tablet tracking from working correctly, meaning finger and pen interaction with the screen is incorrect. When you zoom in on a rectangle in the screen and tap on something, you are...

I have seen code for loading a Win32 library using LoadLibrary and GetProcAddress. How can this be done for a COM DLL file (created in Visual Basic 6.0)? Is there...
Hello, The software company I'm working for builds software for schools, and so our client machines are usually locked down in such a way it makes it pretty impossible for us to install anything on it.

When the application is run on a Windows 7 64 bit machine, the call to MAPILogon fails with a generic error code. Is there an incompatibility with MAPI and Win...
Recently I spent quiet some time writing various Visual Studio Extensions projects. Even though the projects are all managed code to access the core VS services it is still necessary to work with the old style COM interfaces. Here is an example : var selectionTracker = (IVsMonitorSelection)serviceProvider.GetService(typeof(SVsShellM...

Both ComponentA and ComponentB ...

A part of the application that I am working on is a legacy Vb6 Windows forms application. All the files in the project are under source control (VSS) except the Vb6 project file.
