Question

我使用Mingw作为编译器的代码块。我正在开发一个win32项目（winapi）.. 问题似乎是codeblocks无法访问某些Windows标头... 在我的特殊情况下，缺少的头文件是commdlg.h并且在该头文件中使用了一个变量，编译器给出了错误：该变量未在此范围内声明...

那么如何使用Mingw使代码块具有所有必需的Windows头文件？代码是

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;
}

现在构建日志是

MinGW包含代码块和Windows标头
