Hi all, I'm trying to remove 2 pictureboxes and do the work with memory
HDC's
This is what is causing my problem, whichever HDC is created first seems to
work fine
but the second HDC is just a black picture.

Sub Setup_HDCs()
Dim MyBM As StdPicture
Set MyBM = PictureFromDC(picShown.hDC, 0, 0, picShown.ScaleWidth,
picShown.ScaleHeight)
HDC_Backup = CreateCompatibleDC(picShown.hDC)
Call SelectObject(HDC_Backup, MyBM.Handle)
HDC_Hidden = CreateCompatibleDC(picShown.hDC)
Call SelectObject(HDC_Hidden, MyBM.Handle)
Set MyBM = Nothing
End Sub


if I bitblt HDC_Backup I get a the correct picture BUT
if I bitblt HDC_hiddem I get a BLACK picture

If I swap the sub above around its always the second HDC that gives the
black picture.
What am I doing wrong?

You can only have one DC selected into a bitmap at a time.
Depending on what you are actually trying to do, you may have to just
duplicate the code.

Presumably you mean
1. You can only have one bitmap selected into a DC at a time
2. You can only have a bitmap selected into one DC at a time

yes the problem was setting MYBM to the same stdpicture
instead of using two picture references for the same picture.
set MYBM1 = the picture
set MYBM2 = the picture
Then I can select each of these into the two HDC's

Thanks for you help
Chris

Is there a reason for the use of a picture object? Since the picture object
'contents' is first retrieved from a DC and later selected into another DC
there is no need for using a picture object - unless the picture object
doesn't get manipulated somewhere else with special picture object methods
of VB.

Yes the picture object is what the user sees in the Picture Box
I'm just using the 2 memory DCs to manipulate regions of this picture and
bitblt it back to the picturebox based on the users interaction.
Its all working fine now, thanks
