LB_GETCOUNT Problem?
Ok, I'm trying to return the number of items in a listbox using the LB_GETCOUNT message, when I do that it returns as a funky square charactor.


Here's a bit of the code:

.data
intItemCount dd 0 ;Listbox item count.

.code
invoke SendMessage,hListbox,LB_GETCOUNT,0,0 ;Get Item Count.
mov intItemCount,eax

push 0
push 0
push offset intItemCount
push 0
call MessageBox ;Display Result.

You have to convert the number to ascii text first. Use dw2a to do that:
.data

intItemCount dd 0 ;Listbox item count. 

buffer BYTE 16 DUP(0)



.code

invoke SendMessage,hListbox,LB_GETCOUNT,0,0 ;Get Item Count.

mov intItemCount,eax



invoke dw2a,intItemCount,offset buffer



push 0

push 0

push offset buffer

push 0

call MessageBox ;Display Result.
