How to hide an external program from the desktop AND taskbar

[Glow]

@PB : The GetWindowLong_(a,#GWL_HWNDPARENT) was indeed the key I tried it with GetParent_(hwnd) before, but I had no success with that. Thanks for your effort. It´s all good now

Cool. Use my procedure and it should work with all window types.

This three code is fantastic

I don't want to be the bad boys :roll:
But, how to do for reappears the windows

For this code :

Code: Select all

; RemoveFromTaskbar by PB. 

Procedure RemoveFromTaskbar(hwnd) 
  If IsWindow_(hwnd) 
    a=hwnd : b=GetWindowLong_(a,#GWL_HWNDPARENT) : If b<>0 : a=b : EndIf ; Needed for "TaskAssign.exe". 
    ShowWindow_(a,#SW_HIDE) : GetWindowRect_(a,win.RECT) : w=win\right-win\left : h=win\bottom-win\top 
    SetWindowLong_(a,#GWL_EXSTYLE,#WS_EX_TOOLWINDOW) :  SetWindowPos_(a,0,0,0,w-1,h-1,#SWP_NOMOVE) 
    SetWindowPos_(a,0,0,0,w,h,#SWP_NOMOVE|#SWP_SHOWWINDOW) : ProcedureReturn 1 
  EndIf 
EndProcedure 

Debug RemoveFromTaskbar(FindWindow_(0,"THG Task Assignment Manager V1.0")) 
Debug RemoveFromTaskbar(FindWindow_(0,"Untitled - Notepad")) 
Debug RemoveFromTaskbar(FindWindow_(0,"Calculator"))

This code :

Code: Select all

task_hwnd = FindWindow_(0,"Caption of the external program") 
OpenWindow(2, 0, 0, 0, 0,#PB_Window_Invisible, "") 
SetParent_(task_hwnd, WindowID(2)) 
ShowWindow_(task_hwnd, #SW_HIDE) 

And the last code :

Code: Select all

ShowWindow_(WindowID(#window),#SW_HIDE) 
SetWindowLong_(WindowID(#window),#GWL_EXSTYLE,GetWindowLong_(WindowID(#window),#GWL_EXSTYLE)|#WS_EX_TOOLWINDOW) 
ShowWindow_(WindowID(#window),#SW_SHOW) 

Or perhaps you have a magic code that works with the three functions

[ts-soft]

Old Thread

Code: Select all

Procedure HideFromTaskBar(hWnd.l, Flag.l)
  Protected TBL.ITaskbarList

  CoInitialize_(0)
  If CoCreateInstance_(?CLSID_TaskBarList, 0, 1, ?IID_ITaskBarList, @TBL) = #S_OK
    TBL\HrInit()
    If Flag
      TBL\DeleteTab(hWnd)
    Else
      TBL\AddTab(hWnd)
    EndIf
    TBL\Release()
  EndIf
  CoUninitialize_()
 
  DataSection
    CLSID_TaskBarList:
    Data.l $56FDF344
    Data.w $FD6D, $11D0
    Data.b $95, $8A, $00, $60, $97, $C9, $A0, $90
    IID_ITaskBarList:
    Data.l $56FDF342
    Data.w $FD6D, $11D0
    Data.b $95, $8A, $00, $60, $97, $C9, $A0, $90
  EndDataSection
EndProcedure

Thanks a lot TS-SOFT

You are always here for help me

Good day for you

[Kwai chang caine]

I have again a little problem.

The function of TS-Soft works fine.

I open my extern application
I reduce her in the taskbar with ShowWindow
I Create a systray icon in the systray
I hide the windows in the taskbar with HideFromTaskBar

All that works fine
I click on the icon in the systray, my extern aplication reappears and his button on the taskbar too.
But when i reduce again my application, the button in taskbar not disappears, normal because i can't catch the event mouse to reduce the application

Somebody know how catch the event reduce of external windows click ?

[Kwai chang caine]

Well, i use again this function

Code: Select all

Procedure RemoveFromTaskbar(hwnd) 
 
 If IsWindow_(hwnd) 
 
  a = hwnd 
  b = GetWindowLong_(a,#GWL_HWNDPARENT) 
  
  If b <> 0 
   a = b 
  EndIf ; Needed for "TaskAssign.exe". 
  
  ShowWindow_(a, #SW_HIDE) 
  GetWindowRect_(a, win.RECT) 
  w = win \ right - win \ left
  h = win \ bottom - win \ top 
  SetWindowLong_(a, #GWL_EXSTYLE, #WS_EX_TOOLWINDOW) 
  SetWindowPos_(a, 0, 0, 0, w - 1, h - 1, #SWP_NOMOVE) 
  SetWindowPos_(a, 0, 0, 0, w, h, #SWP_NOMOVE|#SWP_SHOWWINDOW)
  ProcedureReturn 1 
 
 EndIf 
 
EndProcedure 

But the reduce button disapears on my extern application

[Kwai chang caine]

I am not come to do reappear the taskbar button.

I have circle the problem like that :

When i clik a first time, the application appears.
And the second time, she desappears

Code: Select all

Procedure RemoveFromTaskbar(hwnd) 
 
 If IsWindow_(hwnd) 
 
  a = hwnd 
  b = GetWindowLong_(a,#GWL_HWNDPARENT) 
  
  If b <> 0 
   a = b 
  EndIf ; Needed for "TaskAssign.exe". 
  
  ShowWindow_(a, #SW_HIDE) 
  GetWindowRect_(a, win.RECT) 
  w = win \ right - win \ left
  h = win \ bottom - win \ top 
  SetWindowLong_(a, #GWL_EXSTYLE, #WS_EX_TOOLWINDOW) 
  SetWindowPos_(a, 0, 0, 0, w - 1, h - 1, #SWP_NOMOVE) 
  SetWindowPos_(a, 0, 0, 0, w, h, #SWP_NOMOVE|#SWP_SHOWWINDOW)
  ProcedureReturn 1 
 
 EndIf
