I am migrating my WIN32 application to WIN64 application. I have compiled the code for x64 platform. While running this application in debug mode I am getting the error message as
"First-chance exception at 0xf41b1a6e in xxx.exe: 0xC0000005: Access violation at location 0x00000000f41b1a6e."
This exception occurs when I execute below code.
SetWindowPos (lpI->hTop, NULL, 0, 0, cx, cy, SWP_NOZORDER | SWP_NOACTIVATE);

Please help me to resolve this issue.
