Any way in the framework to get the .exe file path from a particular extension?

TIA

You will have to look at the registry under HKEY_CLASSES_ROOT and then examine the keys under the extension.I would suggest that you open regedit for example,expand the HKEY_CLASSES_ROOT and look for .sln.There you will find a subkey called OpenWithList and where you will find devenv.exe.

Here is a bit of code that helps you associate an extension with a program.You can use this and it makes very interesting reading

The registry value for .sln seems to be : VisualStudio.Launcher.sln

I need to get the Program exe name and path of associated extensions.

Since you??e already found how to find the name of the handler for the given file type, you next would need to locate that handler, also within HKEY_CLASSES_ROOT where for the .sln file you have found the name to be VisualStudio.Launcher.sln, you should see a key by the name of Shell, which itself contains an Open key which in turn contains Command that has the default value of the path to the executable and any necessary arguments.

Does that get you closer?

I used to do this in VB with psapi.dll...

Can't locate the code tho.
