just for my education... in your shared method or method within a class idea... if the click routine only contains data/controls that are within formA. is a delegate the answer or do you have another technique?
If I read this correctly... If the click handler only does some kind of setup for the form itself, then yes, I'd use a delegate to make the call. But, I've never sen the need to have a child dialog, or any other form, tell another form how to set itself up. I've always used a shared state object and/or events fired by the data model to tell the subscribers that they might want to adapt to a change in the data.

2006, 2007the only situation I can think of is when formB is a modal form and it's answer will dictate what formA will do... dim oFrm as formB If oFrm.showdialog() = DialogResult.OK Then 'change the state of formA . . . if they are independent of each other then I would agree...

Then FormB exposes it's status as properties. FormA then decides what it's going to do with that data and alters its own user interface accordingly. FormB should never know anything about the form that launched it.

I sure hope your high on something. It's the only explanation for a statement like that.

2006, 2007I think we missed/missing each other's points. if i'm in formA and I create and instance of formB, I have 2 options of displaying formB... SHOW and SHOWDIALOG if i use SHOW then you are correct, formB shouldn't need to know anything about A but if it does, use a delegate. if I use SHOWDIALOG that A is waiting for B to respond with the user's choice of pressing OK or Cancel or whatever choices remain in the enum dialogresult. So B will return the answer and A reacts accordingly. No different then an OK/Cancel messagebox. I personally have no issue with A reacting to B in this situation...

Hi, I have two seperate forms. Lets just call them FormA and FormB. I have a function in FormA called Button_Click(). How would I (while in FormB) call this function? I have tried, while in the FormB code, using Form_FormA.Button_Click. But that doesn't seem to work. Can anyone help me with this?
Hi, this is a way that you can use if you are calling formB from formA, if not you can use the Sub Main to keep active forms references. In FormB Private m_f As FormA Public Sub New(f as FormA) m_f = f MyBase.New End Sub ... Call m_f.TheMethod In FormA ...ButtonX.Click Call TheMethod End Sub Public Sub TheMethod ... End Sub ... dim f as New FromB(Me) f.Show Hope this helps! NajiCo http://www.InsideVB.NET[^]
