Multiple DLL versions

Multiple DLL versions

I am developing an application that uses many DLLs (Qt and VTK). When I invoke the program from within VS, all works fine. When I double-click on the .exe file, it fails because it finds the wrong QtCore4.dll - there are several on my machine, associated with different software (e.g. Matlab).

When I execute the program within a command window, I can control the DLLs that are found by setting environment variables appropriately. What is the recommended way to achieve this when running the program from the Windows GUI?

For more complete information about compiler optimizations, see our Optimization Notice.

You may write a .bat file which including the environment setting and the call to your exe, theninvoke the bat file from windows GUI.
Or you can set upthe properenvironment variables in the system environment variable settings.

Thanks, I forgot about the bat file option.
