Positioning forms

Question

Hi All,
I want to do two things.
1. I have a MDI and when a specific form  load it should position in the middle of the MDI. For example login window should load in the middle of MDI.

2. I have a MDI and I can load some windows inside that. And I some of those windows load other windows too. I want to position them in the middle of window which is used to call them

Please post some sample code on how to do this.

Hi Kirtan,
Sweet. It's working. I think issue No1 is solved now.

But any idea about issue two? Do I have to handle this in from level instead of MDI level?

Answer 4

Hi Kirtan,
There is a problem in that approach which I already tried. The problem is related to part 1. My Login form loads when the MDI is loading. So when I add that code segment I get the error "Top-level control cannot be added to a control."

About the second part..the problem that child window is loaded from MDI window. the MDI should listern to key board and load the window in the middle of currently focused form inside MDI.

So I'm sorry I don't think that suggestion will work.
