在“另存为”对话框前面显示弹出消息

在Windows应用程序中，打开“另存为”对话框后，是否可以在“另存为”对话框前面显示弹出消息？我所得到的只是对话框关闭后弹出窗口显示。

我需要编辑一个用 C++ 编写的旧应用程序（我不是作者），但无法管理此任务。这是代码的一部分：

/* ---- 调用以显示保存文件对话框 ---- */

ofn.hwndOwner = hwnd; 
ofn.lpstrFile = lpstrFileName; 
ofn.lpstrTitle = lpstrTitleName;

res = GetSaveFileNameW( &ofn );

/* ---- fix file extension ---- */

MessageBox(NULL, "Test", "Testing", MB_OK);

谢谢，
伊利亚

In Windows application, is it possible to show a popup message in front of SaveAs dialog after SaveAs dialog is being opened? All I managed to get is that popup shows after dialog is closed.

I need to edit an old application written in C++ (I am not author) but can't manage this task. This is part of code:

/* ---- called to display the save file dialog ---- */

ofn.hwndOwner = hwnd; 
ofn.lpstrFile = lpstrFileName; 
ofn.lpstrTitle = lpstrTitleName;

res = GetSaveFileNameW( &ofn );

/* ---- fix file extension ---- */

MessageBox(NULL, "Test", "Testing", MB_OK);

Thanks,
Ilija

如果我理解正确，您想在关闭对话框之前检查一些内容（例如文件扩展名）并在不关闭的情况下显示消息。如果是这样，请查看 OPENFILENAME 结构。在这种情况下，您的代码将类似于

ofn.hwndOwner = hwnd; 
ofn.lpstrFile = lpstrFileName; 
ofn.lpstrTitle = lpstrTitleName;

/* enables the hook function */
ofn.Flags |= OFN_ENABLEHOOK;
ofn.ofn.lpfnHook = (LPOFNHOOKPROC) MyHookProc;

/* some code here */

res = GetSaveFileNameW( &ofn );

MyHookProc 的代码将如下所示：

static UINT CALLBACK MyHookProc( HWND hDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    if (uMsg == WM_NOTIFY) {
        OFNOTIFYW *notify = (OFNOTIFYW *) lParam;

        if (notify->hdr.code == CDN_FILEOK) {
            /* your code here */
        }
    }
}

希望它会对您有所帮助。

If I understand you correct, you want check some stuff (for example, file extension) before closing dialog and show message withou closing. If it's so please look at OFN_ENABLEHOOK flag in OPENFILENAME Structure. In this case your code will look something like

ofn.hwndOwner = hwnd; 
ofn.lpstrFile = lpstrFileName; 
ofn.lpstrTitle = lpstrTitleName;

/* enables the hook function */
ofn.Flags |= OFN_ENABLEHOOK;
ofn.ofn.lpfnHook = (LPOFNHOOKPROC) MyHookProc;

/* some code here */

res = GetSaveFileNameW( &ofn );

Code for MyHookProc will look like this:

static UINT CALLBACK MyHookProc( HWND hDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    if (uMsg == WM_NOTIFY) {
        OFNOTIFYW *notify = (OFNOTIFYW *) lParam;

        if (notify->hdr.code == CDN_FILEOK) {
            /* your code here */
        }
    }
}

Hope it will be helpful for you.
