MinGW with codeblocks and windows headers - codeblocks

Question

I'm using codeblocks with Mingw as my compiler. I'm working on a win32 project (winapi)..
the problem it seems codeblocks does not have access to some windows headers...
in my particular case the header missing is commdlg.h and using a variable in that header the compiler gives me error : the variable was not declared in this scope...
so how do I make codeblocks have all the necessary windows headers using Mingw?
the code is
bool Gui::_browseForFile(HWND owner, LPWSTR initialDir, LPWSTR fileBuffer)
{
OPENFILENAMEW ofn;
Mem::_zero(&ofn, sizeof(OPENFILENAMEW));
ofn.lStructSize = sizeof(OPENFILENAMEW);
ofn.hwndOwner = owner;
ofn.lpstrFile = fileBuffer;
ofn.nMaxFile = MAX_PATH;
ofn.lpstrInitialDir = initialDir;
ofn.Flags = OFN_DONTADDTORECENT | OFN_ENABLESIZING | OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_PATHMUSTEXIST;
return CWA(comdlg32, GetOpenFileNameW)(&ofn) ? true : false;
}
now the build log is
