That's fine, no need to shout, there clearly aren't a lot of XPCOM guru's here so I suggest you either post the specific errors and ask a specific question (It all looks like pretty standard C++ stuff so you might get some help) or look for a dedicated XPCOM developer community elsewhere. If there isn't one out there then my original comment about obscurity stands.
Nothing is exactly what it seems but everything with seems can be unpicked.

Hi all,
Look at the following lines.
char *tempBuff[1024];
unsigned int iReq;
I want to copy the tempBuff to another buffer, adding the iReq to in-front of the tempBuff. How it is possible.
I appreciate your help all the time...

Are you sure your buffer should contain 1024 char pointers?

Sorry it should be char tempBuff[1024]

char tempBuff[1024];
unsigned int iReq;
char newBuff[1024 + sizeof(iReq)];
memcpy(newBuff, &iReq, sizeof(iReq));
memcpy(newBuff + sizeof(iReq), tempBuff, 1024);

TO CPallini:
Then how to read the first four bytes out to form the int value?
<br />
char tempBuff[1024];<br />
unsigned int iReq;
char newBuff[1024 + sizeof(iReq)];<br />
memcpy(newBuff, &iReq, sizeof(iReq));<br />
memcpy(newBuff + sizeof(iReq), tempBuff, 1024);
Can this achieve?
<br />
int *iptr = &newBuff[0];<br />
int iTReq = *iptr;

Yes.

The code is correct, provided you cast the pointer, i.e.
int *iptr = (int*) (&newBuff[0]);
int iTReq = *iptr;
you can also do directly
int iTReq = *((int*)(&newBuff[0]);
or
int iTReq = *((int*)newBuff);
Cheers

You can delete them just like you would any other file. What extension the file has is unimportant.

do you have compiled your project as unicode ?
if not, make sure that you use
preprocessor definitions ( c++ page )
_UNICODE
output (link page) - entry point symbol
wWinMainCRTStartup
further on you could use _T("") instead "" in your code
hope it helps

|

no sir its not coming....

i think you are correct
perhaps you could use CEdit instead but if not keep in mind
RichEditCtrl in Visual C++ 7.0 supports Unicode. To obtain Unicode strings from the RichEditCtrl box, use EM_GETTEXTEX message instead of GetDlgItemText.
SendMessage(
EM_GETTEXTEX,
(LPARAM) &getTextEx, // GETTEXTEX structure
(WPARAM) lpszWChar // output WCHAR array
);

Hi friends,
I am trying to allocate around 3 sets of nearly 1.8MB of memory with calloc inside OnInitDialog() function of MFC. I used a memory leak detector tool and before I could start the worker threads I was able to see memory leaks in the lines which I used to allocate the memory mentioned above. Is there any issue in using calloc for memory allocation more than 64KB. I am using Win2000 with Visual studio 6.0 (VC++).
Following is the code snippet I used.
char *source_buf;
unsigned long size = 9001;
source_buf = (char*) calloc((size*200),sizeof(char));

Does your application check calloc return value?
Does it free allocated memory?

I am not checking calloc value. But in debug mode I have watched the pointers. They are valid ones. At the same time I would like to mention that I am not freeing them anywhere in the code because this buffer is used cyclically throughout the runtime of the code by the worker thread. The pointer is duplicated for use by the worker thread.
char *store_buf;
store_buf=source_buf;

Since you are using MFC, why are you avoiding the new operator?

I am a bit curious about why to use new in MFC. What is the danger which is avoided by using 'new' and why such a precaution in MFC. I am almost unaware about MFC and its fundamentals.. That's why I am curious about the above issue

For integral types, there's not much difference other than the ability to track down memory leaks. For classes/objects, the new operator will also call the constructor.

I created a context menu and displayed it using TrackPopupMenu. I do not use TPM_RETURNCMD. My application window receives the result of user selection.
It works fine if I select/click some menu item - the window receives message for the given menu item. However if I cancel the context menu (hit Esc or click somewhere else) I do not receive any message. Is there any mechanism to catch context menu cancel event?
Another question, how to determine if a context menu (CMenu) is active and displayed?
Thanks,
Abyss
