Ok, here's more specifics. I'm trying to get my list control to sort on a column heading click. You code just handles the click message. Do you know what additional code I'd have to add to get the list view to sort by the column heading that was clicked on?

You'll need a handler for the LVN_COLUMNCLICK notification. In the handler, the column clicked is obtained like:
void OnColumnclick(NMHDR* pNMHDR, LRESULT * )
{
CWaitCursor cursorWait;
NM_LISTVIEW *pNMListView = (NM_LISTVIEW *) pNMHDR;
if (m_list.GetItemCount() > 0)
{
m_nSortColumn = pNMListView->iSubItem;
m_list.SortItems(CompareFunc, ...);
}
}

I tried your code and lSize and i have the same value.
|
|

|
|
Yes,Same here.

Ok, so what's the problem? You instructed it to read lSize bytes and it read i bytes, both of which were the same.
|
|
|
|
|
Thw point is that svRead does not contain all datas.

How do you verify this? Does a byte with value of zero at the fourth or fifth position confuse your viewer?
My opinions may have changed, but not the fact that I am right.

Yes,I guess this is the problem.

Don't use fopen() or the other C runtime file functions from <stdio.h> for reading binary data. They're only designed for use with text files.
Under Windows, use CreateFile() to open a file and ReadFile() to read data from it. You can also use the _open() function and _read() to read from the file, which may be more portable (the POSIX binary functions are named open() and read()).

Where did you get this from? fopen(), fread(), fwrite(), and fclose() operate on both text files and binary files. They always have.

Don't you have to add a flag or something in order to read binary data?
Perhaps not with the fXXX() family... I don't have MSDN near my hands so I can't check if it is so.

Have you tried using any of the m-type symbols in the watch window?
I use these two quite often:
m
ma
I've never used these:
mb
mw
md
mq
mu

If you have access to CodeProject, you have access to MSDN[^]

True, but I don't waste any time and money of big loadings at MSDN online with my damn modem!

Why you don't use the Win32 API functions CreateFile, ReadFile, ... ?

I use this coed to read files:
FILE *file = fopen(szpath,"rb");
if(file!=NULL)
{
char *svRead;
fseek (file , 0 , SEEK_END);
long lSize = ftell (file);
rewind (file);
svRead = (char*) malloc (lSize);
int i = fread(svRead,sizeof(char),lSize,file);
}
But it works only for TEXT files ad when I read jpg files with it ,it only read 3 or 4 first character.
