Unload Form in SDI environment

[bungpeng]

In SDI environment, how do I unload other form?

 

For example: form A open form B, now form B want to unload form A.

 

TQ

You will need to pass a reference to Form A to form B. Search these forums and you'll find a good few samples on this.

I did search in this forum before post this question...

 

Pass reference to Form A to Form B... I think I understand that, it means if I never pass, then there is no way to unload the form A?

[snarfblam]

give formB a property or function (or constructor parameter) that allows formA to send its reference to formB, ie:

 

Private Dim FormToClose as Form
.
.
.
Public Sub SetFormToClose(FormA as form)
   FormToClose = FormA
End Sub[/Code]

 
so that anytime formb can just call [code]FormToClose.Close

 

After FormA creates FormB, FormA should make the call

FormB.SetFormToClose(Me)[/Code]

to provide formB with a reference to itself

Thank you very much! I understand what you mean.

Remeber that if you close the the form on which the application loop depends then the whole application closes. So if you start with FormA it might be a better idea to hide it.
