Value of Progress bar control

[AllenP]

I've been looking around for examples, but have not found any as yet.

I want to know what the value of a progress bar is. I want to use this in more than one application, but an example would be during a backup using NTBackup. I assumed I would have to use one of the control tools, but for the life of me I have no idea where to start. I did run the Window Info Tool, and it provided the following info...

Could someone point me in the right direction?

Something like the following should do it:

Const $WM_USER = 0x400
Const $PBM_GETPOS = ($WM_USER+8)
$h_progress = ControlGetHandle("Backup Progress","","msctls_progress321")
$ret = DllCall("user32.dll","int","SendMessage","hwnd",$h_progress,"int",$PBM_GETPOS,"int",0,"int",0)
MsgBox(0,"Percent",$ret[0])

Thanks for the quick reply... and really I appreciate the code... but I would also like to understand what its doing...

Would you mind commenting each line?

For your reference, I am a well versed in Kixtart and Shell Scripting, but I've not quite got my hands around AutoIt yet... but I want to.

Thanks for your time.

From the help file:

ControlGetHandle

--------------------------------------------------------------------------------

Retrieves the internal handle of a control

DllCall

--------------------------------------------------------------------------------

Dynamically calls a function in a DLL.

From MSDN:

The DLLCall is a little over my head, and have no idea why the constant values are defined as they are... but moving on to my next question. Your script worked very well within AutoIT, however now I am trying to convert it to Kixtart and use AutoItX. My converted script errors out on the DLLCall line, and unless I'm missing it, DLLCall does not appear to be one of the methods in the control. Is this correct, and if so, is there another method that would allow me to do it?

Thanks

[GaryFrost]

Never had a need for the AutoItX, can't help you there, sure someone can tho

I dont think that DllCall() is a KixStart function. (I am not positive I grasped your meaning).

Why would you want it to be in Kix when it works perfectly well in AutoIt?

Well... not to ruffle anyone's feathers around here, but KiXtart is my main tool of choice. I'm sure most of you know what I mean when I say I would like to keep everything within the script, not having to call EXEs, etc, nor do I want to re-write all my scripts to AutoIT. That being said, I was hoping to convert the script above using AutoItX... and everything worked until it got to the dllcall, which I don't think is something AutoItX supports, although I hope I am wrong and someone can point me in the right direction.

Here is the script if anyone is interested.

break on
$WM_USER = &400
$PBM_GETPOS = $WM_USER+8

$AutoIt=CreateObject("AutoItX3.Control")
? @error
while $ret<=100
  $h_progress = $Autoit.ControlGetHandle("Backup Progress","","msctls_progress321")
? @error
  $ret = $Autoit.DllCall("user32.dll","int","SendMessage","hwnd",$h_progress,"int",$PBM_GETPOS,"int",0,"int",0)
? @error
  $ret
  sleep 0.2
