Accessing an event of another form

[uniquegodwin]

I have 2 forms...imagine form A and form B...
I would like to access Form B's paint event from Form A ..

and I would like to set e.graphics.fillrectangle(example,something) of the other form.

Can someone advice me about that?
Thanks

I think part 3 refers to accessing events or subs on other forms...

(this link has been getting good use lately)

Declare a variable of type FormB as WithEvents in FormA. You can then handle its events just like you would any control or component that you added in the designer. Alternatively you can use the AddHandler statement. A form is an object just like any other, and you can handle its events like you would any other. We're used to handling a form's events inside the form itself but that's not necessary. It is important to remember that each form you design is just a class like any other, and each instance you create is just an object like any other. Form's are not really any different to anything else you work with in .NET.

Hi Jm,
Im actually trying to use a function and do this..

ublic Function changecolor()
        For Each child As Form In parent.MdiChildren
            Dim g As Graphics = child.CreateGraphics()
            Dim rec As New Rectangle(0, 0, child.Width, child.Height)
            Dim lbr As New LinearGradientBrush(rec, Color.DarkOrange, Color.CadetBlue, LinearGradientMode.Vertical)
            g.FillRectangle(lbr, rec)
           
            child.Hide()
 
 
        Next child
    End Function

but It does what it has to just for a second...I think the logic is wrong...Im not sure how to do that permenant change on the paint event

Thanks for the competition,Im also learning faster and getting to finish my work faster

You can create a Paint event handler in your parent form and then use AddHandler to link it to the Paint event of each child. That handler can then do the drawing. I haven't tested that but I believe the thoery is sound.
