SomeBody can make this ?

[fnajar]

I like to make a Program in VB that can make a window ( or program )dissapeared from the window's task bar, but the program keep loaded.
(Sorry my english)

Use the ShowWindow API.

Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long

Private Sub Command1_Click()
    Dim hApp As Long
    hApp = FindWindowEx(0, 0, "SciCalc", "Calculator")
    If hApp <> 0 Then ShowWindow hApp, 0 '<-- Change 0 to 1 to display the Window again
End Sub
