Progress Bar without animation in Vista/7

5 posts in this topic

#1 ·  Posted (edited)

When I started using Windows 7, I saw the following feature. The state change of the Progress Bar is not jumping, like Windows XP, but smoothly (animation), naturally it takes a while. It certainly looks nice, but in some situations is not necessary. For example, when displays a copying files. I could not disable this animation by using API, and I had to write your own Progress Bar which completely match the current theme. Optionaly, you can specify one of four colors: green (default), red, yellow, or blue (see screenshot). The following example will work properly only in Windows Vista/7, and only for a themeable windows (not classic). I hope this will be useful to someone.

Great script. This will be rather useful. But what is state 4 (blue progress)?

Global Const $PBM_NORMAL = 0x0001
Global Const $PBM_ERROR = 0x0002
Global Const $PBM_PAUSED = 0x0003

As far as I know there is only three states? What is the fourth state that makes it blue?

Also in this example state 4 does nothing?

#include <GUIConstantsEx.au3>
#include <ProgressConstants.au3>
#include <SendMessage.au3>
$status = 0
$hGUI = GUICreate("Test", 500, 50)
$hbar = GUICtrlCreateProgress(10, 10, 400, 20)
GUICtrlSetData($hbar, 80)
GUISetState()

While 1
    Sleep(1000)
    $status += 1
    If $status > 4 Then $status = 0
    _SendMessage(GUICtrlGetHandle($hbar), $PBM_SETSTATE, 0x000 & $status, 0)
    WinSetTitle($hGUI, "", "State -> " & $status)
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

I don't use GUICtrlCreateProgress(), I draw a Progress Bar by using DrawThemeBackground() function. The reason for which I wrote _SetProgress() is getting rid of the animation in Windows Vista/7. Different colors are of secondary importance. I don't know why PBM_SETSTATE message not support PBFS_PARTIAL (blue), but it's present in the theme.

EDIT:

Moreover, your example is not working properly (the state 100...).

This is a workaround to "disable" the animation

GUICreate("Progressbar Win7/Vista Test", 220, 50)
$cProgress = GUICtrlCreateProgress(10, 10, 200, 20, 0x01)
GUISetState()

While 1
    $iValue = Random(0, 99, 1)
    GUICtrlSetData($cProgress, $iValue + 1)
    GUICtrlSetData($cProgress, $iValue)
    Sleep(1000)
WEnd
