Im using a LB_GETTEXTLEN to get the length on of the string but how do i make the buffer ?
VB Code:
use either:
new
or calloc() (malloc() in disguise)
after using the buffer, call either delete or free(). delete goes with new, free() with calloc().
Forgot to say ima newB how do i do it? can i get a sample. Ill research on msdn but can u gimme a sample please thanks

You can use others function to allocate the string buffer like mention by jim mcnamara.PHP Code:{ADDED}
char *sBuf = [color=red]NULL[/color];
int iList;
int iSel;
int iSel2;
iSel = ::SendMessage(list,LB_GETCURSEL,0,0);
iSel2 = ::SendMessage(list,LB_GETTEXTLEN,iSel,0);
// Allocate & Initialize the string buffer
sBuf = (char*)LocalAlloc(LPTR, iSel2+1);
memset(sBuf, '\0', iSel2+1);
::SendMessage(list, LB_GETTEXT, iSel, (LPARAM)sBuf);
// iList = ::GetWindowTextLength(list);
// ::GetWindowText(list,sBuf,iList);
::SetWindowText(edit,sBuf);
// Free the used resource
LocalFree((char*)sBuf);
Thats the error i get with your code:
VB Code:

VB Code:
The sample code is filered by the PHP tag,
it should be
VB Code:
YES Great thanks
if i had a million dollars.......
..........I'd be rich! lol
Learn C++.
are you talking to me? Cuz if you are you must not be very smart, because what do you think im trying to do?
You are using MFC without knowing enough C++ for it. That's what you're trying to do, and it's a bad thing.
Isn't LocalAlloc depreciated science Windows 3.1?
Use HeapAlloc() instead.
Deprecated ;) Depreciated means losing its value...in this case partially correct though.
{Local,Global}Alloc were designed more around 16-bit programming, yes.
Yep, those two were built around the special memory model of Winx.x. I'm happy I didn't program back then.
:p, i should change my code to use HeapAlloc from now.
The only one of those function that should still be used is LocalFree, because FormatMessage allocates with LocalAlloc if requested to allocate memory.
