'System.OutOfMemoryException' UGH!

im creating just a simple MDI app and to add a child window i use this code..

Dim NewMDIChild As New Form2()
NewMDIChild.MdiParent = Me
NewMDIChild.Show()

and it worked, but after a bit i got an error

An unhandled exception of type 'System.OutOfMemoryException' occurred in system.windows.forms.dll

Additional information: Error creating window handle.


Now im guessing i am not freeing up my childs after i create and close them, because of the OutOfMemoryException part.

If this is the case, how do i free them when the app closes?


P.S Side question
I would like
Dim NewMDIChild As New Form2()
NewMDIChild.MdiParent = Me
NewMDIChild.Show()
in a module, but if i change the

newmdichild.mdiparent = me to
newmdichild.mdiparent = Form2

it doesnt work, how can i do this?

thanks

I recently ran into this problem as well, if you create a Public variable of type Form2 and then in Form2_Load assign a reference to Form2 to that variable, you should be able to access it no problem.

here's what i'm talking about

[in Module1.vb]
Public myForm1 as Form1 'this variable will be accesible to the whole project

[in Form1.vb]
Private Sub Form1_Load(blah, blah blah)
myForm1=me
End Sub


Now whenever you want to access Form1's properties and furthermore the controls contained therein, instead of using Form1 as the variable, use the reference stored in myForm1. I think that should solve your problem.

But this question is two years old :D
Infact, can't even remember the question. Ohwell useful for archive purposes

I'm getting this same exception, with the "error creating window handle" message, and I can't figure out why. This is C#, but the code is easy to read.

When I had this code in the constructor, the MDI child form shows just fine

PHP Code:

---

            Tables t = new Tables(); // Tables is a Windows form
            t.MdiParent = this;
            t.Show(); 


---

But when I put the same exact code in the method that executes when you click a button, I get the OutOfMemoryException

PHP Code:

---

        private void miServerData_Click(object sender, System.EventArgs e)
        {
            Tables t = new Tables(); // Tables is a Windows form
            t.MdiParent = this;
            t.Show(); // Error on this line
        }

I'm trying to track it down, can anyone help?

Thanks,
Mike
