drawing a rectangle in a form

[reidarT]

I try to draw a rectangle in a form on a buttons click event, The code is
Dim bitmap As New Bitmap("lysblaa .jpg")

Dim tBrush As New TextureBrush(bi tmap)

Dim texturedPen As New Pen(tBrush, 30)

e.Graphics.Draw Image(bitmap, 0, 0, bitmap.Width, bitmap.Height)

e.Graphics.Draw Ellipse(texture dPen, 100, 20, 200, 100)

I get an error on e.Graphics...

I have trie to set Imports System.Drawing. Design but it doesn't help

Re: drawing a rectangle in a form

I have tried to do like you suggested with this code

Private m_Button1Clicke d As Boolean

Private Sub Button1_Click() Handles Button1.Click

m_Button1Clicke d = True

Me.Invalidate()

End Sub

Private Sub Form_Paint() Handles MyBase.Paint

If m_Button1Clicke d Then

e.Graphics.Draw Image("1.jpg")

End If

End Sub

but I get n error on Button1.click and e.graphics

The methods's signatures are wrong. I didn't include the complete parameter
list because I didn't test the code in the IDE. Instead I just used
ellipsis instead to simplify typing the post. I suggest to create handlers
for the button's 'Click' event and the form's 'Paint' event using the IDE by
selecing the object in the left dropdown list on top of the code editor and
then selecting the event in the combobox on the right hand side.

e.Graphics.Draw Image("1.jpg")

\\\
Private m_Image As Image = Image.FromFile( "1.jpg")
....
Private Sub Form_Paint(...) Handles MyBase.Paint
e.Graphics.Draw Image(m_Image)
End Sub
