MDI Forms - Opening child

[RTorrance]

Hello,
I am having a problem with opening a second child form in my MDI Parent. I have 3 forms, one being a parent and 2 children. I open the first child from a menu and then from this form i want to open the second child and close the first child. I have tried numerous ways and looked through this forum and cannot get it to work. I can get it to close the first form, but can't get the second one to show up at all. Any help would be appreciated. Thanks.

To show a form on MDI parent try this,

form1.DefInstance.Show()

or this...

Dim Form1 as new Form1
Form1.Show()

hope it works

Thanks for the reply. Your answer works when opening the child form from an MDI parent. The problem comes in when trying to open a child form from another child form. As was stated in the original message of this thread:

"I have 3 forms, one being a parent and 2 children. I open the first child from a menu and then from this form i want to open the second child and close the first child. I have tried numerous ways and looked through this forum and cannot get it to work. I can get it to close the first form, but can't get the second one to show up at all."

This is exactly the problem I am having and I don't understand why the child form will not show.

Any further clarification will be greatly appreciated.

The following seems to work:

Dim MyMDIParent = Me.MdiParent.FindForm
Dim ChildForm as New frmChild

ChildForm.MdiParent = MyMDIParent
ChildForm.Show()

Still not quite sure why it works, but it does and for that I am grateful.

Thanks for trying to help.
