Drawing a progress Bar

[iamtheky 711]

I am working now to try and get it to use many shades of a single color, but my color palette hex value knowledge is lacking.

the second example was more for my daughter as she totally loves colored blocks.

Single Line

    $each  = @DesktopWidth / $Blocks

For $i = 1 to $Blocks
    $Rcolor = random (0x000000 , 0xFFFFFF)
For $x = $each * ($i - 1) To $each * $i
For $y = $Top To $Bottom

    _PixelSetColor ($x , $y , $Rcolor)

Next
Next

If $i = $Blocks Then
$i = 0
$Top = 0
$Bottom = 81
$Blocks = Random (3 , $MAX , 1)
$each  = @DesktopWidth / $Blocks
Endif
Next


Func _PixelSetColor($XCoord, $YCoord, $Color)
    Local $dc = DllCall("user32.dll", "int", "GetDC", "hwnd", 0)
    If Not IsArray($dc) Then Return -1
    DllCall("gdi32.dll", "long", "SetPixel", "long", $dc[0], "long", $XCoord, "long", $YCoord, "long", _
            "0x" & StringRegExpReplace(hex($Color,6), "(..)(..)(..)", "\3\2\1")) ; Change to 0xBBGGRR hex colour format.
    DllCall("user32.dll", "int", "ReleaseDC", "hwnd", 0, "hwnd", $dc[0])
EndFunc ;==>_PixelSetColor

Thats a lovely story, but any chance you could explain your problem?

It will help you get a quicker answer?

iamtheky, try to move  "$Rcolor = random (0x000000 , 0xFFFFFF)" above "_PixelSetColor ($x , $y , $Rcolor)". This does not solve the problem with the shades (I'm thing at it...), but... see for yourself.

M.I.

I am working now to try and get it to use many shades of a single color

I was hoping maybe someone had a way to specify a range of shades in the same color, in a hex manner.

so the first sentence was my issue.

That must make the 14 word second sentence the lovely story. /

@Taitel -- thats why i added the 3rd For Loop - if there was a way to scrub the screen like that at a faster speed it would be a nice tv noise effect.

Maybe this gives you some ideas:

GUICreate("Gradient...", 500, 400)
GUISetState(@SW_SHOW)
;   Example
_Gradient(0xffff00, 0xff0000,480,10,10,10,0)
Sleep(200)
_Gradient(0x001100, 0xffff00,460,360,20,30,1)

While 1
    Sleep(10)
    Switch GUIGetMsg()
        Case -3
            Exit
    EndSwitch
WEnd

That is very nice Taietel. Thanks.
