Not really. The compiler treats constant variables very similarly to #defines. It replaces the value of ch with 'c', which is what it is initialised with, simply because it is constant. The compiler does not care what sort of pointer trickery you perform. It assumes that a constant variable is constant, which it should be.

Hi all, first post here 
I have a Custom AppWizard project right now. How can I set, from code, the Executable for debug session and specify Additional DLLs of the generated project? I have looked at the IBuildProject and have customized several preprocessor and linker options with it. I have also located where the Executable for debug session and Additional DLLs information is stored (opt file) but it's Binary so I dont think I can edit it directly.
I hope there is a way...

Friends,
I was playing with "Windows Media Player", suddenly an error occured in the application. A dialog box popped up on which the name of "cpp" was written and also the line number in "cpp" file also written where the error occured.
I also want to add such feature in my release builds. How can i do so ?

Use __FILE__ and __LINE__ constants to do it.
like this:
char lpBuffer[240];
sprintf(lpBuffer,"File: %s\n Line:%d",__FILE__,__LINE__);
MessageBox(NULL,lpBuffer,"Message",MB_OK);

I've subclassed CButton to draw the text with different fonts and font sizes. The problem is that when the focus rectangle is draw on radio buttons and check boxes it's size is relative to the default font.
Is there anyway to change the size of the focus rect or to draw it myself?
Thank you

You can draw a focus rectangle using DrawFocusRect() (or CDC::DrawFocusRect() if you're using MFC). You'll have to calculate the size of the rectangle yourself.

I know that! The problem is that when the control has focus there will be two rects. I was looking for a way to tell windows the size of the rect, or to disable windows to draw it so that I could draw it myself.

Good 
Unfortunately, you can't tell Windows the size of the focus rect.
The only way to prevent Windows from drawing the focus rect is to completely handle WM_PAINT without relying on the default at all. The best way would be to make an owner-draw control - then you wouldn't have to worry about subclassing it - MFC would do the hard work for you. You'd have to do all the painting yourself, but DrawFrameControl() could take some of the hard work out of it .
Hope this helps

I'm handling WM_PAINT. But windows still draws de focus rect.

Try handling the WM_SETFOCUS/WM_KILLFOCUS messages and draw/erase the focus rect yourself (don't call the base).

I'd recommend creating an owner-draw control. Windows won't draw anything for an owner-draw control, and delegate everything to your control.

try taking a look at the classes present here in CP, my favourite is the one from Davide Calabro CButtonST, it has a lot of properties and it's great to learn how to manage things like what you want to do...
hope this helps...

Dear all,
This may seem like a strange question but I am working with some old 16 bit windows applications build with Visual Studie 1.52.
I was wondering if there are any way to force this application to have more process time from the OS?
Best regards

Windows 3.x uses cooperative multitasking, not preemptive multitasking like Win95 and later. If you just hog the processor, you cut out other processes.
From memory (admittedly, my Windows 3.x memory is a little bit rusty ), Windows only switches between processes when a process calls the Yield() or GetMessage() functions. If you call them less often, then you get more processor time, at the expense of other processes.

The 16-bit app runs in a 32-bit VDM process, so you can do the following:
Right click the app's pif and set the Idle sensitivity to low.
-or-
Boost the priority of the VDM process.

Yes. Look at the AlphaBlend() function.
