Prevent window caption blinking on activation

I have an icon in system tray.
Double click on that icon fires an event in which I'm using me.show to make the window appear.
But when it appears, its not activated like the caption is grayed out and it blinks 3 times unless I click on it.
AppActivate solves the problem but I can't use it since I have multiple instances of my program running at the same time and they all have same caption while appactivate works on caption title so I want an alternate.

Note: setactivewindow, setforegroundwindow, setdesktopwindow, me.setfocus e.t.c nothing works.

Hasan,

This might work (if not, plz let me know):

''bas code:
Public Declare Function SetFocusAPI Lib "user32.dll" Alias "SetFocus" (ByVal hWnd As Long) As Long

''form code:

Dim retval As Long  ' return value
' Give your form's hWnd focus
retval = SetFocusAPI(me.hWnd)


If you have flashing problems, try this, too:

''bas code

Private Type FLASHWINFO
  cbSize As Long
  Hwnd As Long
  dwFlags As Long
  uCount As Long
  dwTimeout As Long
End Type

Private Const FLASHW_STOP = 0

Private Declare Function FlashWindowEx Lib "user32" _
   (FWInfo As FLASHWINFO) As Boolean

''form code:

Dim bRet As Boolean
Dim udtFWInfo As FLASHWINFO

Dim Hwnd as Long, Dim uCount As Long

hWnd = me.hWnd
uCount = 1

With udtFWInfo
   .cbSize = 20
   .Hwnd = hWnd
   .dwFlags = FLASHW_TRAY
   .uCount = uCount 'flash window x times
   .dwTimeout = 0
End With

bRet = FlashWindowEx(udtFWInfo)

It doesn't blink anymore but still it ain't activated.

I've found a perfect solution to the problem.
I temporarily add few white spaces at the end of the caption.
Do the AppActivate on it and then change it back.

Nothing else works for me.

''bas
Declare Function SetForegroundWindow Lib "user32" (ByVal hWnd As Long) As Long

''form
SetForegroundWindow me.hWnd

     Ack, you've already tried that... nm... Perhaps use SetForegroundWindow in combination with the remove blinking code? I'm out of ideas.. :)
