问题描述

我有一个全屏运行的VB应用程序.单击VB应用程序上的按钮后，将打开一个小程序.单击小程序上的按钮后，它将调用c ++ dll(吐温)，并且该dll具有创建弹出窗口的代码，并且该窗口位于全屏VB应用程序的下方，而不是位于顶部. >
有人可以让我知道将弹出窗口显示在全屏VB表单和小程序顶部的方法吗?

在此先感谢，

Hi,

I have a VB application that runs full screen. On the click of a button on the VB application, an applet is opened. On the click of a button on the applet, it calls a c++ dll (twain) and this dll has the code to create a pop up window and this window goes underneath the full screen VB application instead of being at the top.

Can someone let me know the way i can get this pop up window onto the top of full screen VB form and the applet?

Thanks in Advance,
Kris

推荐答案

您可以在vc ++ dll中实现以下内容

You can implement following into vc++ dll

CWnd *pCalc = CWnd::FindWindow(NULL, _T("Applet Name"));
if(pCalc != NULL)
{
   pCalc->BringWindowToTop();
   pCalc->CenterWindow();
}

您还可以使用MoveWindow();.要将窗口移到大小合适的位置.

You can also use MoveWindow(); To move window at desried location with size.

只需在创建该窗口时将窗口设置设置为OnTop.

Just make the window settings to OnTop while creating that window.

如果可能，您应该通过窗口作为父窗口调用的过程的句柄.否则，您可以安装一个钩子来做到这一点(SetWindowsHookEx(WH_SHELL，...)).捕获HSHELL_WINDOWCREATED消息并将您的窗口设置为父窗口(SetParentWindow或SetWindowPos或SetForegroundWindow等.pp.).
问候.

If possible you should pass your window handle to the called procedure as parent window. Otherwise you can install a hook to do that (SetWindowsHookEx(WH_SHELL,...)). Catch the HSHELL_WINDOWCREATED message and set yout window as parent (SetParentWindow, or SetWindowPos or SetForegroundWindow etc. pp.).
Regards.
