C# API
C# winform,调用一个外部exe程序,请问有什么办法,控制这个exe程序窗体显示大小和显示位置,谢谢!

------解决方案--------------------
MSDN 查查这个Process类,看看Demo就知道了
------解决方案--------------------
启动:
shellexecute()
createprocess()
winexec()
大小和位置:
setwindowpos()
查找窗口:
findwindow()
enumwindows()
------解决方案--------------------
Process.start
------解决方案--------------------
You can choose to start the process with a minimized, maximized or normal window (by setting the ProcessStartInfo.WindowStyle and using the Process.Start(ProcessStartInfo) method). However, you don't really have control over the size of the window of the outside process when you start it. 

Once you launch the the program, you can get it's main window handle using Process.MainWindowHandle.

Given the window handle, you should be able to P/Invoke SetWindowPos to position or size that window

帮顶,可以在程序中启动,控制大小。。。待研究!!

自己慢慢琢磨,记得给分哦
C# code
