getopenfilename多选文件/文件夹问题和getsavefilename另存为路径

关于使用getopenfilename多选多个文件是可以的。

以下是多选文件的代码

bool GetNeedOpenFilePath(vector<tstring>& vectFiles, HWND hwnd )
{
    OPENFILENAME ofn;
    TCHAR szOpenFileNames[80*MAX_PATH] = {0};
    TCHAR szPath[MAX_PATH];
    TCHAR szFileName[80*MAX_PATH];

    int nLen = 0;
    TCHAR* p = NULL;
    ZeroMemory(&ofn, sizeof(ofn));

    ofn.lStructSize = sizeof(ofn);
    ofn.hwndOwner = hwnd;
    //ofn.hInstance = (HMODULE)GetCurrentProcess();
    ofn.lpstrFile = szOpenFileNames;
    ofn.nMaxFile = sizeof(szOpenFileNames);
    ofn.lpstrFile[0] = _T('');
    ofn.lpstrFilter = _T("All Files(*.*)*.*");
    ofn.nFilterIndex = 1;  
    ofn.lpstrFileTitle = NULL;  
    ofn.nMaxFileTitle = 0;
    ofn.lpstrTitle = I18NSTR(L"#IDS_FILESYSTEM_OPEN_FILE_DIR");
    ofn.Flags = OFN_ENABLESIZING | OFN_FILEMUSTEXIST| OFN_ALLOWMULTISELECT| OFN_HIDEREADONLY /*| OFN_ENABLEHOOK *//*| OFN_ENABLEINCLUDENOTIFY*/| OFN_EXPLORER;
    //ofn.lpfnHook = OFNHookProc;
    if (!::GetOpenFileName(&ofn))  //如果打开文件失败，则不操作
    {
        return false;
    }

    //把第一个文件名前的复制到szPath,即:  
    //如果只选了一个文件,就复制到最后一个'/'  
    //如果选了多个文件,就复制到第一个NULL字符  
    lstrcpyn(szPath,szOpenFileNames,ofn.nFileOffset);

    //当只选了一个文件时,下面这个NULL字符是必需的.  
    //这里不区别对待选了一个和多个文件的情况

    szPath[ofn.nFileOffset] = '';
    nLen = lstrlen(szPath);
    if (szPath[nLen-1] != '\')  //如果选了多个文件,则必须加上'//'  
    {
        lstrcat(szPath,_T("\"));
    }

    p = szOpenFileNames + ofn.nFileOffset;  //把指针移到第一个文件  
    ZeroMemory(szFileName, sizeof(szFileName));

    while(*p)
    {
        //lstrcat(szFileName, szPath);     //给文件名加上路径
        //lstrcat(szFileName, p);             //加上文件名
        tstring tstrFile = _UTILITY::TCHARToUnicode(p);
        tstring tstrFilePath = szPath;
        tstrFilePath += tstrFile;
        vectFiles.push_back(tstrFilePath);
        //lstrcat(szFileName, _T("
"));   //换行
        p += lstrlen(p) + 1;             //移至下一个文件
    }

    return true;
}

但是关于使用getopenfilename()函数获取多选文件夹的路径问题，需要自定义一些模板资源。具体实现方式还需研究下。

使用getsavefilename()函数可以获取另存为路径：

bool GetSaveAsFilePath(tstring tstrFilePath, HWND hwnd)
{
    OPENFILENAME ofn;
    TCHAR szOpenFileNames[80*MAX_PATH] = {0};
    TCHAR szPath[MAX_PATH];
    TCHAR szFileName[80*MAX_PATH];

    int nLen = 0;
    TCHAR* p = NULL;
    ZeroMemory(&ofn, sizeof(ofn));

    ofn.lStructSize = sizeof(ofn);
    ofn.hwndOwner = NULL;
    //ofn.hInstance = (HMODULE)GetCurrentProcess();
    ofn.lpstrFile = szOpenFileNames;
    ofn.nMaxFile = sizeof(szOpenFileNames);
    ofn.lpstrFile[0] = _T('');
    ofn.lpstrFilter = _T("All Files(*.*)*.*");
    ofn.nFilterIndex = 1;  
    ofn.lpstrFileTitle = NULL;  
    ofn.nMaxFileTitle = 0;
    ofn.lpstrTitle = I18NSTR(L"#IDS_FILESYSTEM_SAVE_AS");
    ofn.Flags = OFN_HIDEREADONLY | OFN_PATHMUSTEXIST | OFN_EXPLORER;
    ofn.FlagsEx = OFN_EX_NOPLACESBAR;
    //ofn.lpfnHook = OFNHookProc;
    if (!::GetSaveFileName(&ofn))  //如果打开文件失败，则不操作
    {
        return false;
    }

    tstrFilePath = ofn.lpstrFile;
    return true;
}
