Here's some code I put together, add it to a Form with a Picturebox, set the Forms ShowInTaskbar Property to False and it should work fine:

private Type NOTIFYICONDATA
cbSize as Long
hwnd as Long
uID as Long
uFlags as Long
uCallbackMessage as Long
hIcon as Long
szTip as string * 64
End Type

private Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (byval dwMessage as Long, lpData as NOTIFYICONDATA) as Long

private Const NIF_ICON = &H2
private Const NIF_MESSAGE = &H1
private Const NIF_TIP = &H4
private Const NIM_ADD = &H0
private Const NIM_DELETE = &H2
private Const NIM_MODIFY = &H1
private Const WM_MOUSEMOVE = &H200
private Const WM_LBUTTONDBLCLK = &H203
private Const WM_LBUTTONDOWN = &H201
private Const WM_RBUTTONDOWN = &H204

private tTrayIcon as NOTIFYICONDATA

private Sub Form_Load()
'Create a Tray Icon
Picture1.Visible = false
With tTrayIcon
'Image to Display in the System Tray
.hIcon = Icon
'Window Handle to Recieve Tray Icon Messages
.hwnd = Picture1.hwnd
'Tray Icon Tool Tip
.szTip = "My Tray Icon" & Chr(0)
'Message to Direct to Assign Hwnd
.uCallbackMessage = WM_MOUSEMOVE
'What to Change/Add to this Tray Icon
.uFlags = NIF_ICON Or NIF_MESSAGE Or NIF_TIP
'Unique ID for the Tray Icon
.uID = 1
.cbSize = len(tTrayIcon)
End With
'Add the Icon to the Tray
Shell_NotifyIcon NIM_ADD, tTrayIcon
End Sub

private Sub Form_Resize()
DoEvents
If WindowState = vbMinimized then
'If the Form is Minimized, Hide it.
Hide
End If
End Sub

private Sub Form_Unload(Cancel as Integer)
'Remove the Tray Icon
Shell_NotifyIcon NIM_DELETE, tTrayIcon
End Sub

private Sub Picture1_MouseMove(Button as Integer, Shift as Integer, X as Single, Y as Single)
'This Sub Recieves the WM_MOUSEMOVE Message from the Tray Icon
Select Case ScaleX(X, vbTwips, vbPixels)
Case WM_RBUTTONDOWN
'Show Popup Menu Here
Case WM_LBUTTONDBLCLK
'Show the Form Here
WindowState = vbNormal
Show
End Select
End Sub

Sorry for improper language that I'm about to use Mr.PanasonicSubz, but why are you *****ing about something that you didn't read? It's not our problem that you have attitude problem, that you DO NOT read replys to your OWN postings, and that you never rate anyones CORRECT reply? People at this forum have no intention answering your postings because you never rate them and/or you start to blame others for your own "mistakes", but people still answer your postings, so you should just shut up and act like normal person by reading replys and rating correct answers

Have a nice day.

Do you want a DLL which contains all the C++-Code?


You only must Declare 3 functions:
AddTaskbarIcon
ModifyTaskbarIcon and
DeleteTaskbarIcon.


In the beginning I wanted to write this (non-ActiveX; dynamic link; it requires nothing else, no registry etc. and is faster than VB; it's size is only 32KB [for you free to use in your apps]) library for my C and C++ apps, but it also works with VB fine.

But to react to window-messages you must get the WM_-Message by calling the function
GetNotifyIconMessageNumber fron this DLL.

That's all!

If you'd like it, send me a private message and I'll send it to your e-mail address; if you like some example code, too.


Good luck!
