I'm trying to set up a Midi application. I've got a MID-Form and some other forms which should show up as children.

But Calling the show() method (after setting childform.mdiparent to the Mid-Form) does not result in the desired effect. They show modal/ as popup.

If I just instance a blank form, this works.

Is there any property to put attention to or something else that prevents a form from being shown as a child?

Solution 1

I just created a windows forms project. Added an MDIForm, and 2 forms, dropped a button on the MDI surface and in the click event for the button did the following;
Dim form1 As New Form1
Dim Form2 As New Form2
Form2.MdiParent = Me

And it worked as expected, Form1 appeared outwith the mdi and Form2 appeared in the mdi.

I finally found the error...

I created an instance of Form2 (lets say _F2), but I did not set the instances (_F2) property MDIparent to Form1, but Form2's property (class itself). VB did not throw an exeption and it took me a while until I discovered the mistping.

thanks a lot!
