调整大小并重新放置使用createprocess创建的应用程序?

问题描述

我正在使用createprocess执行一个应用程序，例如记事本.

I'm executing an application say notepad, using createprocess.

我需要覆盖该应用程序的默认大小和位置，因此我修改了STARTUPINFO，并指定了dwX，dwY，dwYSize，dwXSize并向dwFlags添加了STARTF_USEPOSITION || STARTF_USESIZE.

I need to override the default size and position of that application so i modified STARTUPINFO, and specified dwX,dwY,dwYSize,dwXSize and added STARTF_USEPOSITION||STARTF_USESIZE to dwFlags.

但是应用程序根本无法打开.
如果我放入STARTF_USEPOSITION和STARTF_USESIZE之一，则应用程序会打开，但不会重新定位或调整大小.

But the application is not opening at all.
If i put one of STARTF_USEPOSITION and STARTF_USESIZE, the application opens but not reposition or resize.

反正有这样做吗?

{
STARTUPINFO         siStartupInfo;
PROCESS_INFORMATION piProcessInfo;


memset(&siStartupInfo, 0, sizeof(siStartupInfo));
memset(&piProcessInfo, 0, sizeof(piProcessInfo));

siStartupInfo.cb = sizeof(siStartupInfo);
siStartupInfo.dwFlags = STARTF_USEPOSITION|STARTF_USESIZE;//||STARTF_USESHOWWINDOW;
siStartupInfo.wShowWindow=SW_SHOWDEFAULT;
siStartupInfo.dwX=900;
siStartupInfo.dwY=300;
siStartupInfo.dwXSize=1000;
siStartupInfo.dwYSize=1000;

if(CreateProcess("H:\\WINXP\\system32\\notepad.exe",     // Application name
                 NULL ,                 // Application arguments
                 0,
                 0,
                 FALSE,
                 NORMAL_PRIORITY_CLASS,
                 0,
                 0,                              // Working directory
                 &siStartupInfo,
                 &piProcessInfo) )
    printf("Sucessful\n");
else
    printf("Error");
}

推荐答案

应用程序可能会忽略STARTUPINFO中的所有数据，或仅使用wShowWindow.

Application may ignore all data in STARTUPINFO, or use only wShowWindow.

您可以尝试依次使用WaitForInputIdle，FindWindow和SetWindowPos.

You can try to use WaitForInputIdle, then FindWindow and then SetWindowPos.
