I think this function can be used to prepare a CMapStringToOb object before adding a known number of data. It clears the map and then can pre-allocate an internal buffer, so the next insert operation will perform faster. This function is optional, but is useful when you know how many items you will insert (the default hash-table size is fairly small -- see the source of this function).
This function is not used for sorting. By sorting the hash-table you probably mean sorting of keys. In my opinion you have to extract all of the keys from the hash-table, put them in an array (CStringArray) and sort it separately. For instance, investigate the qsort function.
If you are familiar with STL library, you can use another kind of collections and the provided sort function.

Plese help!
I use VC7 I need to transform an image (stretch only) in my app and as a result to have only one exe file.
I'v used CxImage class from this site and it worked, but i have to problems.
1. Using of this class needs to include lib in package with my prog.
2. If I make in project setting "Use MFC as shared DLL", then it requires mfc70d.dll and others... and if i set "Use MFC in shared library", i can't use CxImage. it says:
error LNK2005: _fclose already defined in libcmtd.lib(fclose.obj)
error LNK2005: _fflush already defined in libcmtd.lib(fflush.obj)
and so on. Please help!

Check the Linker settings..
NODEFAULTLIB etc.

The error messages you mentioned frequently appear when the compiler's options related to single or multithreading are different in your project and in CxImage library.
If you are using a pre-build CxImage library file, you should be sure the "C/C++ --> Code Generation --> Runtime Library" option of your project corresponds to the value used to generate CxImage library.
If you have the source code of CxImage library and use CxImage as a second project of your solution, then it is easy to check if the compiler options are the same in both cases.

And what is the question ? 
(Please, post a specific question, not asking how to do a chat program. The more accurate the question is, the more accurate the answer will be).

From what I interpreted according to your question -
You will need to send each character on to the remote machine as and when it is entered into the edit window from M/C 1 -> M/C 2 and v/v.
You will have to synchronize the sending and receiving of data on both ends with extreme cautions.
Somethings seem HARD to do, until we know how to do them.

I use the event model to receive data from the socket,
How to get packet one another from what I've received?
I tried to use a buffer list (list<char*>) to save data, then to get the packet from the buffer list. Though it can work, not efficient. For example:
while FD_READ
recv(s,buf,1024,0);
buflist.push_back(buf);
buf may have data less than 1024 bytes, so memory is wasted, and a more complicated algorithm is needed to get a packet from the buffer list. Maybe I should allocate another block of memory in the appropriate size, and copy the data to it. But I don't think it is efficient. Is there any efficient way?

Hi,
I have a list control with 4 columns. One of the columns should have 2 subcolumns within it. Could anybody guide me how to go about it?
Thanks!

I don't think there is an easy way to stop the header bar from showing the split without it being owner-drawn.
1- You could always reduce the width of the columns, so it looks like a sub-column.
2- You could also insert the text using some spaces between the two sub-column entries in the same column.
this is this.

hi Naveen,
psheet->SetWizardButtons( PSWIZB_FINISH ) will set the FINSIH button on property sheet and will hide NEXT button,
I want all the buttons Back,Next,Finish,Cancel all the time on all pages of wizard. expect the last page where there will be no Next button.
Also i want to override functionality of Finish Button.
Thanks in advance
