ohh

its not a leakage but this will happen while I am debugging my code and also while I am running my program.

This error is going to terminate my application in between the usage of the system.

So, please give me reply

But you started the thread as a memory leak problem.
The log you have posted doesnot give much information of your problem.
The debugging info only shows the symbol missing error, please refer Iain Clarke's description below.

If your app terminates due to huge memory usage, you have to find it out by reviewing your code (I prefer it), debug, detect using static or dynamic source code analysers like boundschecker, ....

Um, what memory leakage? You're just showing that Visual C++ can't find debugging symbols for system DLLs. This isn't a great shock. This just means that when you're debugging, if the call stack goes through a system DLL, you won;t know the function name.

If this is a real problem, go look at the recently posted article on setting up a symbol server (not sure if that will work with as old a compiler / debugger and 6.0. (I use 6.0, but I also don't use the symbol server)

This may be a bit thick of me... but can't you just use the "Save As..." menu in Word itself? There's a save as RTF option there.

With more complex documents, there probably will be some loss of information, so your initial document will have to be suiatble in the first place.

If you needed to do lots of this, you could probably do some word macroing, but that's outside my realm.

Hi,

in my case i needed to ignore the LIBCMTD.lib ( D for Debug )
You can ignore this library into the project-properties at Link/Linking (*)
Then you choose the second sub-item (under General)
there you can ignore libraries

I hope this will help you

Hello everybody
I have one Function that returned one char* value.
In this function I declare one char* variable and new it.
Like this:

char* CProject::Myfunction(CString strData, CString strPassword,int iRand)<br />
{<br />
	char *chResult=new char[strlen(chDataString)/2];<br />
.	<br />
.<br />
	do something on chResult<br />
.<br />
.<br />
return chResult;<br />
}

In end of function I must return this value.
Where I can delete this pointer?
Pleases help me.

With special tanks and excuse for my bad English language
Good luck

Hi,

not in this funtion.

some where you have the line

char *line = Myfunction(.....);

than you use the line and after it, you delete it via

delete[] line;

I hope it works Smile | :)

I believe you could delete it in the function which calls your Myfunction.

char* ch = Myfunction(...);<br />
.....<br />
delete ch;

Hope this helps. Smile | :)

In that case you must change Myfunction() to return a CString, or you will have a memory leak.

char *temp = Myfunction(....);
CString str = temp;
delete[] temp;

Because i THINK CString copies the char's into his own locatet memory.
So you lost the pointer to the allocated memory of the funtion Myfuntion,
You need to save temporary the pointer, only to delete him.
