<br>内容：请在该消息函数调用ShowWindow(SW_MINIMIZE&nbsp;&nbsp; ),给分吧，我特别需要分！谢谢<BR>CWnd::ShowWindow<BR>BOOL ShowWindow( int nCmdShow );<BR><BR>Return Value<BR><BR>Nonzero if the window was previously visible; 0 if the CWnd was previously hidden.<BR><BR>Parameters<BR><BR>nCmdShow<BR><BR>Specifies how the CWnd is to be shown. It must be one of the following values: <BR><BR>SW_HIDE&nbsp;&nbsp; Hides this window and passes activation to another window.<BR><BR><BR>SW_MINIMIZE&nbsp;&nbsp; Minimizes the window and activates the top-level window in the system’s list.<BR><BR><BR>SW_RESTORE&nbsp;&nbsp; Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position.<BR><BR><BR>SW_SHOW&nbsp;&nbsp; Activates the window and displays it in its current size and position.<BR><BR><BR>SW_SHOWMAXIMIZED&nbsp;&nbsp; Activates the window and displays it as a maximized window.<BR><BR><BR>SW_SHOWMINIMIZED&nbsp;&nbsp; Activates the window and displays it as an icon.<BR><BR><BR>SW_SHOWMINNOACTIVE&nbsp;&nbsp; Displays the window as an icon. The window that is currently active remains active.<BR><BR><BR>SW_SHOWNA&nbsp;&nbsp; Displays the window in its current state. The window that is currently active remains active.<BR><BR><BR>SW_SHOWNOACTIVATE&nbsp;&nbsp; Displays the window in its most recent size and position. The window that is currently active remains active.<BR><BR><BR>SW_SHOWNORMAL&nbsp;&nbsp; Activates and displays the window. If the window&nbsp;&nbsp;is minimized or maximized, Windows restores it to its original size and position. <BR>Remarks<BR><BR>Sets the visibility state of the window. <BR><BR>ShowWindow must be called only once per application for the main window with CWinApp::m_nCmdShow. Subsequent calls to ShowWindow must use one of the values listed above instead of the one specified by CWinApp::m_nCmdShow.<BR><BR>CWnd Overview |&nbsp;&nbsp;Class Members |&nbsp;&nbsp;Hierarchy Chart<BR><BR>See Also&nbsp;&nbsp; ::ShowWindow, CWnd::OnShowWindow, CWnd::ShowOw<BR>

<br>内容：你试试这样.<BR>HWND&nbsp;&nbsp; hw;<BR>hw=::FindWindow(NULL,"testw");<BR>if(hw)<BR>&nbsp;&nbsp;::ShowWindow( hw , SW_MINIMIZE) ;<BR>

<br>内容：你可以点击该类，点击鼠标右键，有Message Handle里，出现菜单，选择WM_KILLFOCUS双击，就会自动在你的.h,.cpp里加上相应的消息函数

<br>内容：没有作用。<BR><BR>我用的是基于对话框的工程，<BR>void CSSMvdmDlg::OnKillFocus(CWnd* pNewWnd) <BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;CDialog::OnKillFocus(pNewWnd);<BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;// TODO: Add your message handler code here<BR>&nbsp;&nbsp;&nbsp;&nbsp;ShowWindow(SW_SHOWMINIMIZED);<BR>}<BR>但是，在主对话框失去焦点，比如被别的窗口遮住时，并不调用OnKillFocus的消息。<BR><BR>该怎么办呢？很着急的。。。<BR><BR>

<br>内容：你是想在同一个程序中实现吗?如是,就用WM_KILLFOCUS消息<BR>如果想让另一个程序使本程序的窗口最小化,就用我上面的代码.其中"testw"是你要最小化的窗口的标题
