我想通过win32中的打开文件对话框获得完整的文件路径。我通过这个功能做到这一点:
string openfilename(char *filter = "Mission Files (*.mmf)\0*.mmf", HWND owner = NULL) {
OPENFILENAME ofn ;
char fileName[MAX_PATH] = "";
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = owner;
ofn.lpstrFilter = filter;
ofn.lpstrFile = fileName;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = "";
ofn.lpstrInitialDir ="Missions\\";
string fileNameStr;
if ( GetOpenFileName(&ofn) )
fileNameStr = fileName;
return fileNameStr;
}
它工作正常并返回路径。但我不能写入那个文件我用openfilename得到它的路径。
注意:我调用此代码写入文件(序列化):
string Mission_Name =openfilename();
ofstream ofs ;
ofs = ofstream ((char*)Mission_Name.c_str(), ios::binary );
ofs.write((char *)&Current_Doc, sizeof(Current_Doc));
ofs.close();
