How to set size of window of an external process?

Question

Hi I have an Windows Forms app and I open an external application from it for example MS Word: Process myProcess = new Process(); myProcess.StartInfo.FileName = winword; myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal; myProcess.Start(); Is it possible to set window size for 'myProcess' lets say w: 1024px and h: 768px and is it possible to disable maximize button. Thanks in advance and best regards.

You would need to enumerate the top-level windows for the process and hopefully the window you want will be the only one. I think there are no .Net classes for enumerating windows of other processes so you would need to use the Windows API. I think you would need to enumerate all top-level windows in the system and select the windows whose process is the same as the one you created. I am not familiar with the latest versions of Word but I think what you are trying to do is more complicated due to Word's use of a single instance of the applicaton. In other words if Words is already executing when you open a document then the process you create using the Process class will pass the document to the existing instance of Word and then exit so the process will go away very quickly So you should use the Word object model or whatever it is called to open the document not the Process class.
