mdiChild Background Worker from mdiParent 1

[FGorilla]

Hopefully a relatively simple question but I can't seem to find the answer.

If I start a backgroundworker on a child form and then want to check it from the parent form to see if it's running how would I go about it?

I've tried calling Form1.BackgroundWorker.IsBusy() but regardless of whether it is running it always returns False.

At the moment I have the code following code to open the form (I check first to see if it's already opened):

Dim NewMDIChild As New Form1()
NewMDIChild.MdiParent = Me
NewMDIChild.Show()
Form1 = nothing

I'm probably being a bit stupid but never mind!

Thanks
Chris

May I ask why you have 'Form1 = nothing'?

'Form1.BackgroundWorker.IsBusy()' won't work because Form1 isn't a usable object (cannot think what its called, sorry).

Try adding 'Public MyChild As Form1' in your Parent form, then do 'MyChild = New Form1...'. When you want to check the Worker, do 'MyChild.BackgroundWorker.IsBusy()'.

Well I've only just started .NET so wasn't quite sure what I was doing. Needless to say I have now removed the offending line!

Many thanks for your reply, it works pefectly.

I'm sure once I get the hang of all the intricacies I'll be fine, it's a little different coming from working with VBA in Access!
