Change the property of an external window

[KKZ]

I have an application (writte in VB.Net) that runs without the ControlBox (just like a splash screen that you cannot move). I want to write a .Net app to change the property of the running application to add a ControlBox so that I move it to my desired location whenever I need it.

Is it possible? If yes, please explain and give example if possible. I will highly appreciate any help. Thanks

Why do you need another application to that?

Thanks for your advice. I did search google, but what I found requires coding in the form that is borderless. My problem is that I am not suppose to make any change in the app that I am trying to move. It is a seperate app (suppose I have no code for that app). I need to get the handle of the required window and see if I can add a ControlBox or any other way that I am able to move it on demand.

You are unlikely to succeed in doing this. It's a security thing -- one process is (generally) not allowed to alter another process' data.

To use Raymond Chen's favorite expression: Imagine if this were true -- you could write an app which could arbitrarily modify another running app. The technique of adding the WindowClass flags to make the system menu appear could easily also take it away. Imagine if someone else's app did that to yours. You'd be upset, right?

If you wrote both applications you could send tcp or udp messages back and forth. You could imbed commands into the tcp /udp messages that either program could interpret and respond accordingly.

You could also do something less dynamic as to use a config file / registry entry and poll the file/registry for changes. Again, passing instructions to the application.

A database backend could also accomplish this. However, these last few ideas all require frequent polling. If you have a tcp/udp listener, the response is immediate.

I would like to thank every one for responding. I tend to agree with Chip that this is meant to be that way.

In the past, I had control over the app and used to work through ini entry or the existance of certain file to flag the system that the app is in development mode and let the app behave differently. However, the current situation is a little different.

I just wanted to see if there is any way of accomplishing this by talking dirrectly with the other app. Thanks again guys. Keep up the good work.
