I am building an app with two MFC classes descended from CDialog.

Probably by the end of it, I am going to have 5 or 6 CDialogs (in a
tabbed window). I have spent quite some time adding custom painting
to the first of them. All of them, in the end, are going to have this
same custom painting going on.

The thing to do then would be to make an intermediate class, MyDialog,
descended from CDialog, with the custom painting in the OnPaint()
method, then derive the 5 or 6 dialogs from that, so I am not
repeating and maintaining the custom painting code in all of my
dialogs.

Theoretically this is very simple ... I create a class MyDialog, then
change the parent class of my dialogs from CDialog to MyDialog, then
transfer the custom OnPaint() method from the dialogs to MyDialog, so
the children all inherit it.

This comes close to just whining ... but maybe somebody knows a good
general-purpose solution to this.

At the moment I am trying to figure out a way to blit a bitmap into a
window, setting pixels in the bitmap to transparent. That is, the
bitmap has pixels that are definitely background, and I want the
window background to show through the bitmap background pixels.

I found this example:

http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/dnarmfc/html/msdn_mfcclip...

which is perfect. What the author is doing is more general than what
I want to do so his approach is more complicated, but I can simplify
it down for what I need.

The problem though is that his example uses HDC and HBITMAP throughout
... but in my app, created using MFC and the visual builder,
everything is in CDC and CBitmap objects.

Theoretically I should be able to do the same things ... but there are
a lot of basic differences ... it isn't just a question of converting
one class of objects to a later extensions of those classes, the whole
approach is different. I've done less work converting perl to c ...

Can a child control have a child control of its own?

I have a (WS_CHILD) listbox control which has a scroll control (WS_CHILD'ed to
the listbox).
The listbox and the scroll control have their own WndProc set by
SetWindowLong(..).

The scroll control is not showing. If I set its parent to be the main window it
shows up OK. If I parent it to the listbox It does not show up. I have
UpdateWindow() WS_VISIBLE set up ok.

My goal is to have the listbox WndProc to handle all the WM_HSCROLL messages.

Hi all,

My app is currently getting the following error when compiled by FASM:

MyApp.asm [62029]:
dd SM_iunknown
error: undefined symbol.

I have no idea what's causing it. :( Any advice on what to check?
I thought it may be due to the GetSystemMetrics API (due to the
"SM" bit) but apparently not after removing calls to it.

So I'm modding this file and I'm trying to put in some print
statements for debugging purposes. The .exe compiles fine and even
gives me runtime errors (stderr.txt) but it won't print to the cmd
line for debugging. I'm new to C++ so don't overlook any obvious
problems. I've tried cout and fprint and neither works. Let me know if
you need anything else for debugging.

Thanks ahead of time!

What happens if a serial communication error occurs with the setting
fAbortOnError=FALSE? Are read and write operations terminated with an
error code (just like with fAbortOnError=TRUE, but no need to use
ClearCommError here) or is the error silently ignored. The MSDN
documentation [1,2] is not very clear on this.

If no error is returned, how do I know the read or write operation was
successfully?

Hi all,

I'd like to get the local app-data directory on my Windows XP
(Brazilian Portuguese version).

I tried the following code:
::SHGetFolderPath(NULL, CSIDL_LOCAL_APPDATA, NULL, 0, pszPath));

But this function returns the following (incorrect) path:
C:\Documents and Settings\admin\Configurações locais\Dados de
aplicativos
which should have been:
C:\Documents and Settings\admin\Configurações locais\Dados de
aplicativos

Any idea what the problem is? Thanks.

This is a follow-up of the prev post which can be found here
http://groups.google.com/group/comp.os.ms-windows.programmer.win32/browse_thread...

To sum up what was discussed in that thread:
I was trying to create a dialog based win32 application. (i.e., The
dialog box was the only window). I had trouble of closing the window
when the user tried to click on the 'X' button. That part was solved!

Lately I've discovered that when I hit the escape key the program
ends. How can I trap the escape key press in this case?

Hello, anyone wants to try my program.
It generates on every run 8 rows of six numbers.
So, you play almost all the numbers, (except one - never mind ;-)) )
It is difficult to play all the numbers only with the pen, difficult to find
what numbers you didn't play. So this program makes easy to do it.

I have more programs to upload in the future, stay tuned.

Good luck
