    form transition and BitBlt problem

    hi all.
    I'm using BitBlt to copy a piece of Form2 to a picture box control in form2 in the Form_Load event.

    The problem is that the program begins with Form1 and no matter what I do, the Bitblt keeps copying its source from those coordinates on Form1

    Form2 is not yet visible, but I've even done form2.show and form1.visible = false to make it use form2, also I used as Source DC
    SourceDC = GetWindowDC(Form2.hwnd)

    What more can I do?

    I am using vbSrcCopy. Is that the problem?

    ANybody?
    thanks

    Heh that's weird, can you post the code here so I have a look at it?
    Code:
    Temp = Me.GetIQ()
'Error 9: Overflow
'DON'T PANIC! :eek:

    never mind. I've moved past that now.

    But this is what I'm stuck on. I used BitBlt to get the image onto the Picture box. Now I want to save the image that is now in the picturebox as a bitmap.

    When I use SavePicture on the .picture , it saves the picture that was originally in picture1, not what I BitBlt to the box. So how can I either:

    Save what is now painted into picture1 as a bitmap
    or
    make this bitblt picture in the picturebox become the .picture for this box.

    either?

    Thanks

    Never mind on that too.

    Picture1.Image, not Picture1.Picture

    Okay, let me get some more work done before I post a problem again
