自定义CFileDialog的问题

[rivershan]

LRESULT CALLBACK CustomWindowProcNew(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam);
WNDPROC hOldProc = NULL;

CFileDialogEx::CFileDialogEx(BOOL bOpenFileDialog, LPCTSTR lpszDefExt, LPCTSTR lpszFileName,
DWORD dwFlags, LPCTSTR lpszFilter, CWnd* pParentWnd) :
CFileDialog(bOpenFileDialog, lpszDefExt, lpszFileName, dwFlags, lpszFilter, pParentWnd)
{
m_ofn.Flags |= OFN_EXPLORER | OFN_ENABLEHOOK | OFN_ENABLETEMPLATE | OFN_HIDEREADONLY | OFN_ENABLESIZING;
m_ofn.lpstrTitle = _APP_TITLE_;
m_ofn.hInstance = AfxGetInstanceHandle();
m_ofn.lpstrFilter = _T("Microsoft Word Documents (*.doc)\0*.doc\0All Files (*.*)\0*.*\0");
m_ofn.lpTemplateName = MAKEINTRESOURCE(IDD_DIALOG_HOOK);

hOldProc = (WNDPROC)m_ofn.lpfnHook;
m_ofn.lpfnHook = (LPOFNHOOKPROC)CustomWindowProcNew;
}

LRESULT CALLBACK CustomWindowProcNew(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_INITDIALOG: //
{
//some opeartions

break;
}

case WM_NOTIFY:
HandleNotify(hwnd, (LPOFNOTIFY)lParam);
break;

case WM_COMMAND:
{
if (HIWORD(wParam) == BN_CLICKED)
{
switch(LOWORD(wParam))
{

}
}

break;
}

}

// return TRUE;
return hOldProc(hwnd, message, wParam, lParam);
}

问题：
要在WM_INITDIALOG里面create几个自画的按钮，所以最后 return hOldProc(hwnd, message, wParam, lParam);

但是缺又拦不到WM_NOTIFY消息了。

不知有什么好的解决办法？

既然还是从CFileDialog派生，那么自定义的文件选择对话框需要这么麻烦么？有很多自定义文件对话框的例子哦

的确麻烦了点

网上很多列子啊。参考其原理，何必自己苦苦思索

要调用CFileDialog的默认处理
return FALSE;
就可以
