    Is it impossible to rotate a picture in an IMAGE Control???

    All I've ever read about picture rotation speaks about a picture box control but never with an image control...

    help me

    Apart from reviving an ancient thread (10 years old), what did you do? You did not provide any information about what exactly are your premises.
    \.ScaleMode is a property available to Forms and PictureBox controls. Maybe you have an Image control which has no ScaleMode. The above sample code seems to relate to PictureBox controls.

    Re: Is it impossible to rotate a picture in an IMAGE Control???

    i am using an image control. i have a report that is based on a table. In that table i have a field that contains a path where the picture is. but the problem is that the pictures are horizontal and i need them vertically on my report.

    i looked in Access 2007, but i can't find the picturebox control. i always get the image control.

    is the picturebox control still available in access 2007?

    Re: Is it impossible to rotate a picture in an IMAGE Control???

    So this is VBA you are talking about.
    I got Office 2003 only here, but can't find a PictureBox either... it seems the PictureBox is intrinsic to VB6.
    Maybe this article and download helps:
    http://www.lebans.com/imageclass.htm
    There is a picturebox emulation for use in Access.

    Re: Is it impossible to rotate a picture in an IMAGE Control???

    As far as I could load the example with Access 2003 there were no severe problems. It is only VBA code, which hasn't changed much since Access95. It describes a class which wraps an Image control and extends its capabilities to draw on it, giving it an hDC (device context handle).
    However it does not feature the Scale/Scalemode of a real picturebox, so it might require some adaptions to the code you have. Instead of ScaleHeight and ScaleWidth you have to use Height and Width.

    Re: Is it impossible to rotate a picture in an IMAGE Control???

    I forgot: In the code you posted, these lines would lead to an error.
    Code:
    pic1hDC% = pic1.hDC
    pic2hDC% = pic2.hDC
    You'd have to use longs for the hDC
    Code:
    pic1hDC& = pic1.hDC
    pic2hDC& = pic2.hDC
    All in all the above code uses no single Dim statement, so it relies upon Option Explicit being off.
    I recommend to change this and declare all variables explicitly to spot errors.

    Doesn't Access 2007 use dot net?

    Well, there is still VBA in it, as I think. I only got 2003 to test for now...

    I looked online, looks like it still uses regular VBA, I too am using 2003
