我在 VC++ 中创建了一个应用程序，问题是如果发生错误，我会显示 MessageBox.但是 MessageBox 没有显示在前面.我必须按 ALT 键才能进入该应用程序.我的应用程序变为非活动状态，直到我按下 ALT.并在 MessageBox 上按 OK.

AfxMessageBox("Win32 MessageMes​​sage",MB_OK | MB_ICONEXCLAMATION | MB_TOPMOST);

推荐答案

需要传递 Handle 才能在 Screen 上显示 Messagebox，您可以使用 HWND WINAPI GetDesktopWindow(void);函数获取桌面的句柄并将其传递到 MessageBox() 函数中.

You need to pass Handle to display Messagebox on Screen, You can use HWND WINAPI GetDesktopWindow(void); function to get the Handle of Desktop and pass this in MessageBox () function.

您可以从

GetDesktopWindoe 检索桌面窗口的句柄.桌面窗口覆盖整个屏幕.桌面窗口是在其上绘制其他窗口的区域.所以这也适用于 OpenGL.

GetDesktopWindoe retrieves a handle to the desktop window. The desktop window covers the entire screen. The desktop window is the area on top of which other windows are painted. So this will work for OpenGL as well.
