I have an owner draw button associated with a bitmap. In the bitmap

middle. What else do I have to do? Please help. Thanks.
One thing you can do--and this works only for some restricted cases, which you may or may
not have--is to make the button background 192,192,192, and when you LoadImage, you
specify LR_MAP3DCOLORS. It will change the 192,192,192 to...owner draw CListBox, how to draw "no item found"

Just thought that if anyone wants to do diagrams with roads or rivers as
double lines then Jeff Lanam (this n/group) kindly provided me with this
link to a free programme called OCAD. Its a tiny file, is EASY to use and
the results can be exported as a .bmp into Publisher.
I asked on this newsgroup how to achieve this and many threads resulted, so
thought I'd post the solution.
Many thanks Jeff (see reply to your post)
Glad you solved your map problem. An interesting program.

I Have program which is drawing objects(PIPES)using the OPENGL. The
labels for the for the PIPE is drawing using the GDI. The text colour for
the labels is same that of the objects. The labels are usually positioned at
out side of the pipe so that it will be visible always. But while rotating
there are possibilities that the labels and objects coincide. I want to set
the labels always visible with respect to the back ground colour.
I used SetRop2() but it has no effect.
Any help would be greatly appreciated
...Putting Bitmap into a Dialog Picture Control
I am trying to use a Picture Control (from the dialog editor) to display
various bitmaps as my program is running.
The general approach is to get the control (pWindow), load a bitmap from a
resource (pBitmap) and call my DrawBitmap function. Everything appears to
work well but no bitmap is drawn. BTW, my Picture Control is of type
"Frame" and it is visible. As an aside, I don't seem to be able to find
much documentation on Picture Control.
Thanks in advance for any suggestions. I would definitely consider another
approach if this is doing it the hard way.

Can you save me the trouble?
I'm looking for a cheap and easy tool to support the control of drawings
(which in fact are currently Word documents) that describe hardware
components and how they build up through sub-assemblies into assemblies and
systems. It needs some version control at the drawing level, and a
baselining function. I know we could do it with something like Dimensions,
or maybe even ClearCase, but they're too big and expensive. If necessary.

A pointer? That isn't likely. You would need the actual image data.
If it really is a handle to a GDI+ bitmap, then look at
Image.FromHBitmap(handle as IntPtr).

I don't think Publisher supports TIFF transparency. It MIGHT transfer
properly to a PDF, but I doubt it.
Publisher does support PNG transparency.
