shellexecute 打开的窗体，如何成为模态对话框！

[vatajoan]

shellexecute 打开一个程序，该程序只有一个窗体，如何让这个窗体成为模态对话框，也就是阻止当前程序的执行，等到这个模态对话框关闭之后，再执行下去 。

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = "c:\\MyProgram.exe";
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteEx(&ShExecInfo);
WaitForSingleObject(ShExecInfo.hProcess,INFINITE);
或：
PROCESS_INFORMATION ProcessInfo;
STARTUPINFO StartupInfo; //This is an [in] parameter
ZeroMemory(&StartupInfo, sizeof(StartupInfo));
StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field
if(CreateProcess("c:\\winnt\\notepad.exe", NULL,
     NULL,NULL,FALSE,0,NULL,
     NULL,&StartupInfo,&ProcessInfo))
{
     WaitForSingleObject(ProcessInfo.hProcess,INFINITE);
     CloseHandle(ProcessInfo.hThread);
     CloseHandle(ProcessInfo.hProcess);
}  
else
{
     MessageBox("The process could not be started...");
}

	   CloseHandle(pinfo.hThread);// close thread at once
	   if (bWait)
	   {
		   if (WaitForSingleObject(hProcess,INFINITE)!=WAIT_FAILED)
		   {
			   DWORD dwExitCode;
			   GetExitCodeProcess(hProcess,&dwExitCode);
			   if (dwExitCode==STILL_ACTIVE) AfxMessageBox("EXE STill ALIVE");
		   }
	   }
	   CloseHandle(pinfo.hProcess);
   }
   return(fsuccess);
}

注意： if (dwExitCode==STILL_ACTIVE) AfxMessageBox("EXE STill ALIVE");

block parent process ? busy waiting ? 这需要在父进程中模拟出一个模态的消息循环来
