Problem with Me.Dispose and Me.Close

Question

Hi,
In certain forms I am having problems with my code. For example when I call frmTwo from frmOne, and want to close frmOne before frmTwo is shown, it does not work. I used code

(In frmOne I wrote)

Me.Dispose
frmTwo.Showdialoge()

frmOne closes but frmTwo does not appear.

If I do it otherwise,

frmTwo.Showdialoge()
Me.Dispose

In this case frmOne keeps running in the background, that I donot want.
Please advise how to manage it.

Thanks and best regards,
Furqan

Using me.close does not change the result.

Sir, if you used 'frmTwo' as a modal dialog, form 'frmOne' should be kept not disposed because its the parent of 'frmOne'.

I' not quote sure, but the second code fragment looks promising so try it like this:

VB

Me.Close()
frmTwo.Showdialog()

Modification
Form.Showdialog() opens a form in modal mode. That means the code following the call of that method will not be executed until frmTwo is closed! See the MSDN documentation.
End modification

Besides that shouldn't it be Showdialog() without an e at the end and parenthesis in the method calls?

Please tell me how this went.

Cheers!

sir, I don't think that you can close a Form then execute any code after that in the same object.

The trick I found is

frmOne.Hide()
frmTwo.Showdialogue()
frmOne.Close()

Or

Just call frmTwo

frmTwo.Showdialogue()
and in its form_load event, close the first form

frmOne.Close()

This is the only workable way I found.

You don't need to dispose it, but close it

VB

frmTwo.Show()
Me.Close

Problem here is that ShowDialog is modal, so the parent form won't be closed until the child's dismissed.

That is what happens when one eye is on the TV the other one on CP and the kid nagging you on the side because.....

I did update my answer, I meant to copy the OP instance name to make it clear, ended up getting everything.
