Hi.

You can use a graphics path to create a region for your button.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.MakeButtonRound(Button1)
    End Sub
 
    Public Sub MakeButtonRound(ByVal B As Button)
        Dim Gp As New Drawing2D.GraphicsPath()
 
        Gp.AddEllipse(0, 0, B.Width, B.Height)
 
        B.Region = New Region(Gp)
 
        Gp.Dispose()
    End Sub

You can combine any number of shapes in your graphics path to create the layout you like.

The sample above will be better illustrated if the button and form are different colors.

I hope this helps you.

wha i am trying to do, is to draw an arrow,

the only way i managed to do that is through using a lable ""->"""
which is not very good aparently, but coz it is a label i coudl moved it, make it visible move to left right, wherever i want to position it....


anyone knows how i can draw a proper arrow, or a small triangle which i can stick it to a square, but at same time , i would be able to change its properties like a control..

thank you very much

sorry about broken english

Hi.

I guess you could make a graphicspath shaped as an arrow, and use it to set the region of a label.

That way you will have an arrow that you can move around like any other control.

Only thing is, that it will only be arrowshaped in runtime.

HOW CAN I DO THAT

Well, basically the same way as the example I posted.
But instead of just adding an ellipse to the graphics path, you would add a series of rectangles and lines to make up an arrow.
Then just set the label region the same way as the button.

Then just set the backgoundcolor of the label to the color you would like for your arrow and you're set.

Here's an example.

Add a label called Label1 to your form.
Set the backgroundcolor of the label to something other than the form.
Set the Size to W=100, H=30
Run this code.

Dim G As New Drawing2D.GraphicsPath()
 
        G.AddRectangle(New Rectangle(0, 10, 85, 10))
        G.AddLine(85, 0, 100, 15)
        G.AddLine(100, 15, 85, 30)
 
 
        Label1.Region = New Region(G)

This should get you started.
