Marquee Style Progress Bar

Is it possible to make a progress bar has "floating" value like this one:


I tried this code

Function SetMarquee

  FindWindow $0 "#32770" "" $HWNDPARENT

  GetDlgItem $0 $HWNDPARENT 1004

  IntOp $1 ${WM_USER} + 10

  SendMessage $0 $1 1 200 $2

FunctionEnd

WM_USER + 10 is the same as PBS_SETMARQUEE,the message to set a progress bar to marquee mode,but it didn't work.Does anybody know how to do it?
Thank you for the attention

There are two problems in your code.

1. The progress bar doesn't have the PBS_MARQUEE style.
2. You passed $HWNDPARENT to GetDlgItem instead of $0.

So, fix those two and you get:

Function SetMarquee

  FindWindow $0 "#32770" "" $HWNDPARENT

  GetDlgItem $0 $0 1004

  System::Call user32::GetWindowLong(ir0,i-16)i.r1

  IntOp $1 $1 | 8 # PBS_MARQUEE

  System::Call user32::SetWindowLong(ir0,i-16,ir1)

  IntOp $1 ${WM_USER} + 10

  SendMessage $0 $1 1 200 $2

FunctionEnd

Is it possible to make the marquee a little bit smoother? The progress sometimes runs faster and suddenly it is slower.

Just to clarify...[list=1][*]XPStyle must be set to on[*]Use 0x400 in place of ${WM_USER} to remove dependency[*]To remove the Marquee effect just XOr instead of Or[/list=1]

Here is my version as a macro I'm using during installation of third party software when the installation time is unknown.

!define SetMarquee `!insertmacro PBS_MARQUEE |`
!define RemMarquee `!insertmacro PBS_MARQUEE ^`

!macro PBS_MARQUEE PBS_MARQUEE_OP
    Push $0
    Push $1
    Push $2
    FindWindow $0 "#32770" "" $HWNDPARENT
    GetDlgItem $0 $0 1004
    System::Call user32::GetWindowLong(ir0,i-16)i.r1
    IntOp $1 $1 ${PBS_MARQUEE_OP} 8 # PBS_MARQUEE = 8
    System::Call user32::SetWindowLong(ir0,i-16,ir1)
    IntOp $1 0x400 + 10 # ${WM_USER} = 0x400
    SendMessage $0 $1 1 200 $2
    Pop $2
    Pop $1
    Pop $0
!macroend

is there a way to set the marquee speed?

That is .NET stuff, you need to send PBM_SETMARQUEE
