Hi,
its me again, Now i am trying to compile and execute the code in the file testWindowWIN32.cpp from the cvs repository. but while during execution when it reaches where the hwnd is set like win->setHwnd(hwnd); an unhandled exception is thrown due to
access violation.it says like
............................................................................
Unhandled exception at 0x00322166 in 03share.exe: 0xC0000005: Access violation writing location 0x000000ec.
............................................................................
the code that i compiled is

That looks like you're using the Tutor ial build system. These projects
don't include the OSGWindowWIN32 lib, as they don't need it. Have you
added it?
