Hi

My app does a few processes and the app can not be closes mid way. Therefore
I want to be able to block any attempt of closing app by user such as by
clicking on close (cross) or Alt-F4 and once the app is finished doing what
it is doing to close. In other words I need to close the app gracefully. How
can I achieve this?

Thanks

Regards

推荐答案

如果应用程序有一个主窗口：处理FormClosing事件并设置

e.Cancel = true;


否则处理windows消息并检查

WM_QUERYENDSESSION：

WM_QUIT：

WM_CLOSE：

干杯，

If the app has a main window: handle the FormClosing event and set
e.Cancel = true;

Otherwise handle the windows messages and check for
WM_QUERYENDSESSION: http://msdn.microsoft.com/en-us/library/aa376890.aspx
WM_QUIT: http://msdn.microsoft.com/en-us/libr...41(VS.85).aspx
WM_CLOSE: http://msdn.microsoft.com/en-us/libr...17(VS.85).aspx
