Iconized application

Hi,

I wish to ask if anyone could explain to me how i can run my programs in iconized form in the system tray.

Try this sites:

http://www.vbsquare.com/tips/tip178.html

and

http://www.vb-world.net/tips/tip61.html

that's it I think

Add this to a module:

Code:

---

Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long

Public 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

Public Const NIF_ICON = &H2
Public Const NIF_MESSAGE = &H1
Public Const NIF_TIP = &H4
Public Const NIF_ALL = NIF_ICON Or NIF_MESSAGE Or NIF_TIP

Public Const NIM_ADD = &H0
Public Const NIM_DELETE = &H2
Public Const NIM_MODIFY = &H1

Public Const WM_MOUSEMOVE = &H200
Public Const WM_RBUTTONUP = &H205

---

Add a PictureBox to your Form and name it picTray.
Set the ScaleMode property of picTray to 3 - Pixels.
Add this to the MouseMove event of picTray:

Code:

---

Dim wMsg As Long
wMsg = X

Select Case wMsg
    Case WM_RBUTTONUP
        'The user has clicked on your icon
        'with the right mouse button. You can
        'add code to pop-up a menu here.
End Select

---

Set the Picture property of picTray to an icon. It's important to add an icon and not a bmp!

Add this to the Load event of the Form:

Code:

---

Dim NID As NOTIFYICONDATA

With NID
    .cbSize = Len(NID)
    .hWnd = picTray.hWnd
    .uID = 1
    .uFlags = NIF_ALL
    .uCallbackMessage = WM_MOUSEMOVE
    .hIcon = picTray.Picture.Handle
    .szTip = "This is my app!" & Chr(0)
End With

Shell_NotifyIcon NIM_ADD, NID

---

In the Unload event of your Form add this:

Code:

---

Dim NID As NOTIFYICONDATA

With NID
    .cbSize = Len(NID)
    .hWnd = picTray.hWnd
    .uID = 1
    .uFlags = NIF_ALL
    .uCallbackMessage = WM_MOUSEMOVE
    .hIcon = picTray.Picture.Handle
    .szTip = "This is my app!" & Chr(0)
End With

Shell_NotifyIcon NIM_DELETE, NID

---

I wrote the code right to the post so let me know if it works.

BTW: If you intend to show your form, you might want to set the Visible property of picTray to False.

This is a simpler way of the above post..a little different as well :rolleyes:.

I recommend the OCX control from Kedaman (KedTray.ocx) because it's really easy to use.
Look at http://www.kedaman.com for the control!
