How to detect when mouse is down

Hi

Hi

I need to know when a Mouse button clicks or has been pushed Down on other Applications

Use the GetASyncKeyState to trap when the mouse has been pressed/is down.


Example:
Add a timer called Timer1 to a form set its interval to 100.

Insert the followinf code

Code:

---

Option Explicit
Private Const VK_LBUTTON As Long = &H1  '//Left mouse button
Private Const VK_RBUTTON As Long = &H2  '//Right mouse button
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer

Private Sub Timer1_Timer()
    Dim lRet As Long
    lRet = GetAsyncKeyState(VK_LBUTTON)
    If lRet <> 0 Then
        Debug.Print "Left Mouse is " & TranslateValue(lRet)
    End If
    lRet = GetAsyncKeyState(VK_RBUTTON)
    If lRet <> 0 Then
        Debug.Print "Right Mouse is " & TranslateValue(lRet)
    End If
End Sub

Private Function TranslateValue(ByVal lValue As Long) As String
    Select Case lValue
        Case 0      'Nothing, 'key' hasn't been pressed
        Case 1      'Huh?
            TranslateValue = "Unkown state"
        Case -32767 'Click, first recording of 'key'press
            TranslateValue = "Pressed"
        Case -32768 ''Key' is down
            TranslateValue = "Down"
        Case Else  'Another, hmmm whats this
            TranslateValue = "Unkown state"
    End Select
End Function

Hope it helps,

Grate It works fine but could you also tell me how to detect other events like dblclicks?

Thanks a lot
