you said char *Input; //better alloc some memory here how do i do that?
and i know why it is not working! cos as soon as Input becomes a char it screws up and does not equal what it should?

char *Input = new char[1024];
or
char Input[1024];

Input cannot be made in to a char as it no longer equals what it should so as a AnsiString it equals: save that{ste} and as a char it equals:ÈóI

Hi,
I would like to pass a metafile from the container to my ActiveX control ( developed using ATL), how can I do that ? ( I always passed bools or number ...  ).
Thanks, Bye !

You can encapsulate your metafile in an object supporting the interface IDataObject. ATL <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_atl_idataobjectimpl.asp">IDataObjectImpl</a> class serves this purpose.

Gracias Joaquin !
I will give a try to that. btw. I continue with my ole and Ms Word do you want to read something funny ? ( check this out from MSDN.... Q241936 ), I thought I was going bananas yesterday 
Bye !

Hola Joaquin !
Do you know where I can find some examples about that issue ? ( IDataObjectImpl). I found samples about getting things from the clipboard, but what I would like to do is from the client app, pass an Metafile to the my ATL/server.
Thanks !, Hasta luego !

I am using VC (MFC also) to develop programs under Visual Studio as IDE. Could anybody here exlain how to used Visual studio to detect memory leak?
|
|
|
|
|
In debug mode, you can use <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/html/_crt__crtmemdifference.asp">_CrtMemDifference</a> and related functions (in <crtdbg.h>) to check for memory leaks caused by C run-time library allocations (malloc, realloc and new).

GOOD LUCK!
C Runtime library for addressing memory, look up _CRT in the MSDN index. Unfortunately, they don't account for all the memory. Beyond that, BoundsChecker by Numega is probably the most popular tool for this purpose.
Hope this helps

Here is an article I found from MSDN. Hope it helps.

Check the CMemoryState class which can be used for debug versions only.

first make this declaration at the top of your stdafx.h file:
#define _CRTDBG_MAP_ALLOC
next make sure that these files are included in your project:
#include <stdlib.h>
#include <crtdbg.h>
finally, when your program shutsdown, you need to call this function:
_CrtDumpMemoryLeaks();
This will produce an output like this:
<br />
Detected memory leaks!<br />
Dumping objects -><br />
C:\PROGRAM FILES\VISUAL STUDIO\MyProjects\leaktest\leaktest.cpp(20) : {18} normal block at 0x00780E80, 64 bytes long.<br />
Data: < > CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD <br />
Object dump complete.<br />
You can click on filename with the line number and it will take you to the place where you allocated the memory. This will be a good place to start.
After you get a list of objects that are leaking, you will now have the allocation number of the block that was leaked. In the example above (18) was the block.
You can run the program again and set a break point when block 18 is allocated. First set a break point right when your program loads.
Declare a variable in your watch window called:
_crtBreakAlloc
Set this variable to 18, this will tell the debugger to break when the 18 block is allocated. With this you can step through the code and know exactly which element that you allocated that is leaking. With this technique it is very important that you perform the exact same operations in the program in order to make the memory allocation follow the same path.
Look up this article on MSDN for more information about this technique:
Detecting and Isolating Memory Leaks Using Microsoft Visual C++ by Edward Wright
This technique is a good, free, place to start, but like other people have said, BoundsChecker is a good place to go if you have the money to buy this tool.

What I do is I also use the define
#define _CRTDBG_MAP_ALLOC
My stdafx.h has this in it :
<br />
<br />
#ifdef _CRTDBG_MAP_ALLOC<br />
#include "crtdbg.h"<br />
#endif<br />
<br />
and I call this little function in OnInitInstance
or during initialization for non-MFC apps.
<br />
<br />
void EnableMemoryLeakDump( void )<br />
{<br />
#ifdef _DEBUG<br />
<br />
int tmp = _CrtSetDbgFlag( _CRTDBG_REPORT_FLAG );<br />
tmp |= _CRTDBG_LEAK_CHECK_DF;<br />
tmp &= ~(_CRTDBG_CHECK_CRT_DF );<br />
_CrtSetDbgFlag( tmp );<br />
<br />
#endif // _DEBUG<br />
}<br />
<br />
I don't call anything else and I get leak reports on termination. This works for MFC and straight-Win32 apps.

Does VC7 support this?
I've been digging through the posts here, and I can't seem to find out. I was hoping someone here could give me a yes or no before I start digging through the M$ site.
And is anyone else disgusted with the state of the VC6 STL implementation code? It has to be some of the worst, most poorly documented code I've seen...

VC 7.1 will.
Allegedly. I've come to take MS statements with a grain of salt. When I see it I will believe it.

LOL. Then my answer will be:

Be more assertive. That has been our problem as developers using MS products.
No, but VC 7.1 should. Damnit!

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

I would normally agree, but it has been publically stated by Mr Lippman from memory that Loki and Boost compile with no problems on their internal build of VC7. I doubt they would pull it off and then not release it.
