Windows 7 taskbar button progress bar

[AlexSchaft]

Hi,

I'm trying to show progress on the windows taskbar via the api from http://msdn.microsoft.com/en-us/library/windows/desktop/dd391698%28v=vs.85%29.aspx but can't seem to get it to work.

Has anyone else done this?

Alex

Just a bump on this in case anyone has done this by now.

Hello,
I resurrect this thread to share a FiveWin support for progress bar in task bar:

Code: Select all  Expand view

#include <fivewin.ch>
#include <slider.ch>

function main()
   LOCAL oDlg, oBru, nSlider := 40
   DEFINE WINDOW oDlg FROM  0,0 TO 500,400 PIXEL TITLE "Test" BRUSH oBru
   
   @   8,8 BUTTON "RESET"      SIZE 80,36 PIXEL ACTION TBL_RESET(oDlg:hWnd)
   @  48,8 BUTTON "PROCESSING" SIZE 80,36 PIXEL ACTION TBL_PROCESSING(oDlg:hWnd)
   @  88,8 BUTTON "PROGRESS"   SIZE 80,36 PIXEL ACTION (TBL_SETPROGRESS(oDlg:hWnd), TBL_SETVALUE(oDlg:hWnd, nSlider, 100))
   @ 128,8 BUTTON "ERROR"      SIZE 80,36 PIXEL ACTION TBL_SETERROR(oDlg:hWnd)
   @ 168,8 BUTTON "PAUSE"      SIZE 80,36 PIXEL ACTION TBL_SETPAUSE(oDlg:hWnd)
   
   @ 208,8 SLIDER nSlider HORIZONTAL RANGE 0, 100 SIZE 380,36 PIXEL ON THUMBPOS TBL_SETVALUE(oDlg:hWnd, nVar, 100)
   
   ACTIVATE WINDOW oDlg
   
return nil

   {
      if (state != -1)
         m_pTaskBarlist->lpVtbl->SetProgressState( m_pTaskBarlist, hWnd, state );
      return m_pTaskBarlist;
   }
   return NULL;
}

      m_pTaskBarlist->lpVtbl->SetProgressValue( m_pTaskBarlist, hWnd, n, m );
   }
}

HB_FUNC( TBL_SETPAUSE ) //  hWnd

#pragma ENDDUMP

Here a test program with C code for slider support, I compiled it with Harbour 3.2, FWH 15.03 and Visual Studio compiler.

Maybe It can be include in the next FiveWin release

Antonino,

Many thanks!

I am testing it with Borland and I get this error:

Borland C++ 5.82 for Win32 Copyright (c) 1993, 2005 Borland
antonino.c:
Error E2141 test.prg 25: Declaration syntax error

We need to make this line Borland 5.82 compatible:

ITaskbarList3* TBL_SetProgressState(HWND hWnd, TBPFLAG state)

[AntoninoP]

Hello,
Sorry, I don't have Borland C++, and googling it I don't know how get it.
Anyway, It looks like a Windows Kit version issue, I am using the version 8.1 .

This code is provide "as is" without warranty of any kind. The entire risk as to the quality and performance of the program is with you.

Antonino,

If I try to build it using FWH\samples\buildh32.bat I get these errors:

It seems to me as you are using C++ mode, not C mode.

[AntoninoP]

Hello,
You are using the C++ style, if you look in ShObjIdl.h at line 17366, you can see: above the C++ interface, with method inside the structure, and below the C interface with a structure of pointers at functions that take as first parameter the pointer of interface.
Anyway:
C++:
m_pTaskBarlist->SetProgressState( hWnd, state );
C:
m_pTaskBarlist->lpVtbl->SetProgressState( m_pTaskBarlist, hWnd, state );

I compile with this command:

Code: Select all  Expand view

hbmk2 taskBarList.prg -gui -i..\include -L..\lib -lFiveH32 -lFiveHC32 xhb.hbc -ldflag=Version.lib -ldflag=oledlg.lib -ldflag=gdiplus.lib -ldflag=/NODEFAULTLIB:libcmt

from the fivewin samples directory.

Here a version that compile in both mode:

#include <fivewin.ch>

I was able to build it removing /TP flag

I have tested it in Windows 10 and it seems not to work:


I click on the buttons and no action is done

going to digg some more

[AntoninoP]

You really hate me! windows 10!!

[Antonio Linares]

Antonino,

This control what is supposed to do ? I don't understand what it is for.

I have seen that it is only available from Windows 7 on

[Antonio Linares]

Ok, I found what it does. The color progress bar shown in the taskbar app icon

I have tested it a few times on Windows 10 and just worked once.

Could other users test this EXE on XP, 7 and 8 ?

https://bitbucket.org/fivetech/fivewin-contributions/downloads/taskbarlist.exe

Thanks for the feedback

[Antonio Linares]

Antonino,

You really hate me! windows 10!!

I use to test Windows betas before they are publically available to check in advance if Harbour/FWH properly work on them

[Antonio Linares]

BTW, Windows 10 10122 is much more stable!

A very good news

I am using windows 7 and It should works fine on Windows 8
On XP it should fails to create the Interface and manage it.
