从基于对话框的程序中运行GUI程序，但等待它关闭。 [英] Running a GUI program from within a dialog based program but waiting for it to close.

问题描述

好的，主题行说明了一切。当用户单击按钮并等待GUI返回时，我需要启动一个Windows GUI程序。我一直在使用:: system而且我可以运行GUI但是:: system函数会立即返回...



任何帮助？



Ron H.

OK, The subject line says it all. I need to start a windows GUI program when my user clicks a button and wait for the GUI to return. I''ve been mucking around with ::system and I can get the GUI running but the ::system function returns immediately...

Any Help?

推荐答案

好问题，罗恩！尝试做这样的事情：

Good question, Ron! Try to do something like this:

STARTUPINFO info={sizeof(info)};
PROCESS_INFORMATION processInfo;
if (CreateProcess(path, cmd, NULL, NULL, TRUE, 0, NULL, NULL, &info, &processInfo))
{
    ::WaitForSingleObject(processInfo.hProcess, INFINITE);
    CloseHandle(processInfo.hProcess);
    CloseHandle(processInfo.hThread);
}

祝你好运！

Good luck!
