1、选择文件并获取相应的路径

OPENFILENAME ofn = { 0 };
	ofn.lStructSize = sizeof(OPENFILENAME);
	ofn.lpstrFilter = _T("所有文件\0*.*");	
	ofn.nFilterIndex = 1;
	ofn.lpstrFile = FileName;
	ofn.nMaxFile = sizeof(FileName);
	ofn.lpstrInitialDir = NULL;
	ofn.lpstrTitle = TEXT("请选择文件");
	ofn.Flags = OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_NODEREFERENCELINKS;
	//ofn.hwndOwner = hWnd;
	if (GetOpenFileName(&ofn))
	{
		
	}

2、选择文件夹获取对应的路径

	BROWSEINFO bi;
	bi.hwndOwner = NULL;
	bi.pidlRoot = CSIDL_DESKTOP;
	bi.pszDisplayName = NULL;
	bi.lpszTitle = NULL;
	bi.ulFlags = BIF_DONTGOBELOWDOMAIN | BIF_RETURNONLYFSDIRS | BIF_NEWDIALOGSTYLE;
	bi.lpfn = NULL;
	LPITEMIDLIST pIDList = SHBrowseForFolder(&bi);
	if (pIDList)
	{
		SHGetPathFromIDList(pIDList, szResult);
		
	}
