Word of advice though... if your counter will be counting a alot of things really fast you may want to only update the display in intervals.

This way the real code processes faster when when windows doesn't have to stop to update the index EVERY time.

The following code shows the basic technique with a Modeless dialog. If you use a Modal dialog, and trigger the counter from, say, a "start" button, then instead of DIALOG DOEVENTS, you would use UpdateWindow() after CONTROL SET TEXT.

#COMPILE EXE
#INCLUDE "DDT.INC"

$AppInfo = "The counter reads:"

FUNCTION PBMAIN
    DIM hDlg AS LONG
    DIALOG NEW 0, "Counter Example",,, 100, 34, %DS_CENTER OR %WS_CAPTION OR %WS_SYSMENU TO hDlg
    CONTROL ADD LABEL, hDlg, 100, "", 10, 10, 80, 14, %SS_CENTER
    DIALOG SHOW MODELESS hDlg
    FOR x& = 1 TO 100
        CONTROL SET TEXT hDlg, 100, $AppInfo & STR$(x&)
        DIALOG DOEVENTS
        Sleep 100
    NEXT x&
    DIALOG END hDlg
END FUNCTION

Don't know how you set text, but of course you need Sleep to give a possibillity to OS to process messages.
Another variant - use UpdateWindow (for DDT - something like UpdateWindow GetDlgItem(hDlg, id)

I've written complex program for number crunching.
However, I would like to display running index from a loop:
say FOR I=1 to 500 ===> Display I.

So I created Main window with CreateWindow and then
Dialog New and I added a Textbox into the Dialog.

The program does not display running index from within the loop
but only when the loop has finished it displays I=500 in the Textbox.
Any ideas, what am i doing wrong?
