MFC表单在单独的线程中

Question

I have console MFC form application that consists from one form. In MFC application contructor thread with task is started :

CfbSrvApp::CfbSrvApp()
{
AfxBeginThread(MTServerThread,0);
}

MTServerThread procedure sometimes needs to show simple text input or yes/no form.

How to create MFC form in separate MTServerThread .

Main form sometimes can be minimised to tray, but input forms should appear to desktop anyway.

Answer 1

1. Derive a class from CWinThread.
2. Overwrite InitInstance
3. Create the Dialog there as known with DoModal
4. Create the new Thread with AfxBeginThread and RUNTIME_CLASS(CYourNewCWiNThreadClass)

Answer 2

Main form sometimes can be minimised to tray, but input forms should appear to desktop anyway.

For what you want to achieve, it is better to create Modeless dialog in the main thread itself. Let the background server thread update the UI of the modeless dialog by sending messages to the main thread. This way you can minimize the main form in tray but still show modeless dialog.
