I am currently writing an application using MFC and C++. I am also using Visual Studio 2008. I have concerns that it is leaking memory and/or has array out of bounds issues. I am thinking about buying Purify to verify this and find these bugs. However, its cost is over 800 dollars which is not in my budget.
I am hoping that somebody out there can recommend another tool which is just as good but has a lower price. One such tool is MPatrol but I have never used it and I am wondering who has and what they think of it.
Thanks
Bob

Are you using new and delete?

David,

Then you should be able to detect most, if not all, memory leaks. Run the application using F5, and when it shuts down, MFC will report what wasn't freed in one of the output windows.

David,
Thanks for the response. When I do that there are no memory leaks reported MFC or Visual Studio. I am thinking that it might be the case that I am freeing memory not allocated or allocating x bytes and using more than x bytes. Not sure.

Bob,
Have you tried DEBUG_NEW[^]?

Hi
I have a third party process that modifies the selected text in the currently focussed application window when a hotkey is pressed (e.g. you select text in your text editor, the process wakes up and shows the modified text in a pop-up window and pastes it to the clipboard). I want to trigger this process from an MFC application. I would have a text window in a dialog box to which I would write text programmatically, then I would send the hotkey event and then finally I would get the modified text from the clipboard.
How can I trigger the hotkey event programmatically? (I know how to send key events to programs but I guess hotkeys are registered in Windows and need different handling).

hi,
May i know what is the better book to start with vc++ and MFC...as i have less time to start working on MFC in my company...

In my experience, just about any introductory book, save those written by Petzold, are good for learning MFC. Once you get the basics, though, I find most books beyond useless.
Having said that, my favorite book is out of print and I don't remember the name, but it started with explaining HOW MFC worked to people who already understood Windows. I then spent time writing small apps and stepping through the MFC code to fully understand what it was doing. Again, though, I'd been programming windows since 3.0 was released and had become quite an expert at it.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Have a look at the MFC section of this article [^].

In the days when we used MFC, we'd books by Jeff Prosise and Mike Blaszczak. They are great authors

Hi there.
I want to learn Multithreading programming in C++, Can some one please suggest good articles for the same.
Just FYI, I am well versed with VC++ but want to use only C++ for a specific purpose.
Thanks

There is a List of 25 primes declared in order and the above colors.
RED = 0X1000;
GREEN = 0x2000;
BLUE = 0x4000;
BLACK = 0x8000;
for ( i = 0; i < 4; i++, Color >>= 1 )
for ( j = 0; j < 25; j++, n++ )
Test[n] = primes[j] | (j << 8) | Color | (1 << (16+j));
<
primes[j] this is using one of the 25 whats in primes in order based on J.
Please what is this doing " | (j << 8) | Color | (1 << (16+j))" Can anyone help.
I know the logic works. But I can't understand what this is doing in the above loop.
Can someone please explain.
Thanks A million

it is time to pick up a book and learn about shift operators. It is the basics of programming. Look for LEFT SHIFT , RIGHT SHIFT , BIT WISE OPERATION...

Hi to all.
I wrote an application which extracts information from contacts in outlook(name,e-mail,different phone and fax numbers and etc.). Everything works fine under winXP, but when installed on Win Vista machine application doesn't show any contact information from Outlook 2003 also on same machine!?
Furthermore there is no error reported from my app, so no issues with MAPI Initialization or retrieving MAPI profiles. It appears like nothing is found?
I'm thinking it can be an Vista issue, I tried with MFCMapi.exe but it couldn't find anything also.
Thanks
