But it is working on Windows 7.
Its throwing following Exceptions whenIi try to open mdi child forms within MDI Parent on Windows XP.

I am trying to do following...

C#

ChildForm.SuspendLayout();
ChildForm.mdiparent=this;
childForm.Show();
ChildForm.ResumeLayout();

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Perhaps the code you are using would help us, just a bit?

i guess if you change your code a little bit as following then there should not be any problem

C#

Child  ChildForm=new Child();
ChildForm.mdiparent=this;
childForm.Dock=DockStyle.Fill;
childForm.Show();

i am sure it will work on both xp and win7.
