next to the Form in the solution explorer there should be a '+'.

Click it and spot the file called *.designer.cs

May I add that it is generally not a good idea to change generated code since changes you make in the designer could change the generated code. Do this with caution Big Grin | :-D

I don't have to click "Show All Files" :S but I am using C# so maybe it's different for the C# VS layout or for C# projects.

If you'd googled it, every exampe you'd have found would be using the windows media player control, except for the one or two that used managed directX

yeah, using managed DirectX fully

i did a media player using managed directX but had to install a third party codec as part of the installation process, to play the avi files.

u can try this if u dont have any other option.

This is only because your AVIs used this codec, and would be the same no matter what you used. If you used avi without a foreign codec, or MPG or WMV, then it would just work

i want to draw a backgroun image on a resizable form. i tried Paint Form_Paint event as follows

e.Graphics.DrawImage( hImage , 0 , 0 , Me.width , Me.height )
this draws only at the updated portion of the window and the previous drawing remains the same, hwo can i draw image on entire window Confused | :confused:

before drawing clear the graphics

Me.CreateGraphics.Clear(Me.BackColor)

then redraw the background image

If my help was helpfull let me know, if not let me know why.

but i think i should use Me.CreateGraphics.DrawImage(h, 0, 0, Me.Width, Me.Height) instead of PaintEventArgs

No, you should not.

You should use the Graphics object that is sent in the PaintEventArgs. It's already created for you, so there is no reason to create another Graphics object. Also, it's cropped to the control that is to be redrawn, so that you don't draw outside the control by mistake.

Further more, if you use Me.CreateGraphics.DrawImage(...) then you don't get any reference to the created Graphics object, so there is no way that you can dispose it properly, which you have to do if you create Graphics objects yourself.

its not working

the below code works for me but Guffa told me that i should use PaintEventArs. If i using the following method to paint i should write the same code on Form_Resize.
is there any another method to show a stretched background image ???

Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
Me.CreateGraphics.Clear(Me.BackColor)
Me.Graphics.DrawImage(hImg , 0, 0, Me.Width, Me.Height)
End Sub

Use e.Graphics instead of Me.CreateGraphics.

I think I have an alternative way to do this which is more elegant

In the constructor of your class you can add this line:
SetStyle(ControlStyles.ResizeRedraw, true)

then from that point windows will stop sending small redraw to part of the control and assume the whole control needs to be repainted when resized.
