PSN_QUERYCANCEL 不关闭属性表
我创建了一个属性表，每个选项卡页共享相同的 pfnDlgProc。在 pfnDlgProc 中，我有以下代码：
switch (msg) {
case WM_NOTIFY:
nmhdr = (NMHDR*)lParam;
switch (nmhdr->code) {
case PSN_QUERYCANCEL:
printf("PSN_QUERYCANCEL\n");
SetWindowLong(nmhdr->hwndFrom, DWL_MSGRESULT, FALSE);
return TRUE;
}
break;
...
}
当我单击属性表上的“取消”按钮时，会打印 PSN_QUERYCANCEL，但属性表不会关闭。这是为什么呢？我还需要做其他事情来允许它/使其关闭吗？我知道我可以将 DestroyWindow(nmhdr->hwndFrom) 添加到处理程序，但这是正确的方法吗？
I have a property sheet that I have created and each of the tab pages share the same pfnDlgProc. In the pfnDlgProc, I have this code:
switch (msg) {
case WM_NOTIFY:
nmhdr = (NMHDR*)lParam;
switch (nmhdr->code) {
case PSN_QUERYCANCEL:
printf("PSN_QUERYCANCEL\n");
SetWindowLong(nmhdr->hwndFrom, DWL_MSGRESULT, FALSE);
return TRUE;
}
break;
...
}
When I click the Cancel button on my property sheet, PSN_QUERYCANCEL is printed, but the property sheet does not close. Why is this? Is there something else I need to do to allow it to/make it close? I know I can add DestroyWindow(nmhdr->hwndFrom) to the handler but is that the proper way to do it?

您正在向您发送通知的窗口句柄上设置 DWL_MSGRESULT，但不一定是您正在为其处理 WM_NOTIFY 的对话框窗口。不要使用 nmhdr->hwndFrom 窗口句柄，而是尝试使用传递给 pfnDlgProc 的 HWND。
You are setting the DWL_MSGRESULT on the window handle that sent you the notification, but not necessarily the window that is the dialog you are processing the WM_NOTIFY for. Instead of using the nmhdr->hwndFrom window handle, try using the HWND that is passed to your pfnDlgProc.
