memory leak in the code?
-
My reply was for check does it with success or no (and my suggestion is when you want to allocate or convert use of try/catch block) and when you got error means that it doesnt allocate any thing to variable.
Thanks Hamid, I have developed a couple of samples, which specific case do you think I need to check? regards, George

Yes that was exactly my point! If you have allocated memory, then you have to delete it. Therefore it is vital to initialize your pointers to 0 before using them. Cheers, Pierre
Thanks for your advice, Pierre! regards, George

If you check each block of your program(for exmaple is hwnd valid,etc) you can almost(not always) sure that you didnt get an exception when you run your program

Hi Hamid, How could I check manually which block is exception safe or not? There are too many runtime errors, like out of memory or input invalid values to new which will cause bad_alloc. :-) regards, George

Well its simple you know some actions will be problem and you can anticipate them a short list like: (1) When you want to read a file or write a file:1-does file exist 2-does this file open with other programs 3- can you write to a file on the cd or no,does file on the floppy drive and does it write-protected or no (2) Database do you have access to database (3) when you need to a handle to a window does return value valid or its null (4) Picture does file a image file or no what was return value (5) when you want to read of internet do you have any connection to internet (6) do you have a valid pointer or its null (7) Dynamic memory,does it valid (8).... ------------------------------ After all of them you must free memory. ;)

Hi Hamid, I am interested. What do you mean "check memory size of a program"? Could you provide some samples or links or more descriptions please? regards, George

My intent is when run your program monitor memory for detaily of your program.

Thanks Hamid, You mean in the current process, monitor the memory consumed by current process? And what is its purpose? If you have some links or samples, it will be better to understand your points. :-) regards, George
