progress bar

progress bar

Postby brewster » Fri Jan 25, 2013 2:02 pm

Hi,
Currently I am building a .dbf of filenames from a Windows folder and its subfolders.

I wish to have a progress bar to display "while" the .dbf is being populated.

I have inserted a progress bar from the testmex.prg sample into my code.

Problem is the progress bar dialog is only displayed upon completion, not while the .dbf is building.

I am unsure how to accomplish the task.

At the risk of leaving something out , I include the entire function.

Any help appreciated,
Bruce S.

Bruce, you can start with this example
Code: Select all  Expand view

/*  SAMPLES\PROGTIME.PRG modified  */
#include "FiveWin.ch"

function Main()
local oDlg, oProg, aFiles:=directory(".\"), oSy, cFile:=""
   DEFINE DIALOG oDlg TITLE HB_Curdrive()+"
:\"+Curdir()+" Directory Scan"
   @ 1, 1 PROGRESS oProg POSITION 0 SIZE 150, 10
   @ 2, 10 say oSy VAR cFile size 100, 12
   @ 2.5,  6 BUTTON "
Scan" ACTION DoScan(aFiles, oProg, oSy, @cFile)
   @ 2.5, 14 BUTTON "
End" ACTION oDlg:End()
   ACTIVATE DIALOG oDlg CENTER
return nil  
*
Function DoScan(aFiles, oProg, oSy, cFile)
local nI
   oProg:nPosition=0
   oProg:SetRange( 0, len(aFiles))
for nI=1 to len(aFiles)
    oProg:nPosition += 1
    cFile=upper(aFiles[nI, 1])
    oSy:refresh()
    syswait()
next
return nil

the "syswait()" is only there to slower the operation.
