Change the size od MDI container in the parent form

[sohaib_a]

Hello, How can you change the size of the MDI container in a MDI parent form?

The control is MdiClient. You just need to enumerate the Controls collection of the form, looking for a control of Type MdiClient. Then you need to turn off the Dock proeprty and set the position and size properties to whatever you need.

Is this the way you mean,but it's not working.When maximize the parent form,the child form maximizes to the entire form.What is the problem? For Each ctrl As Control In Me.Controls If TypeOf ctrl Is MdiClient Then ctrl.Dock = DockStyle.None ctrl.Location = New System.Drawing.Point(1, 107) ctrl.Size = New System.Drawing.Size(769, 434) End If Next

That code works fine and as expected, though I'd probably add an Exit For before the End If. If you're saying that the title bar for the child form takes up the entire width of the patent form, this is the expected behavior and you can't turn it off. If you're saying that if you maximize the parent form and this causes the child form to maximize also, then something in your code is causing this. The code you posted will not do cause that problem to happen.
