For me, the documentation says that the window text parameter may be
null, but it doesn't say that the class name can be. You may need to
include a class name. If you have eMbedded Visual Tools (3.0 if you're
developing for 2002, 4.0 for 2003) you can use the Remote Spy++ tool
to view all of the windows open on your device (Both their class name
and their caption). I develop with C# and all of my windows are of
class name #NETCF_AGL_BASE_. Try changing your statement to
Dim hwnd as IntPtr = FindWindow("#NETCF_AGL_BASE_", "LinkMan")
Good luck,
