Question
Identifying mouse clicks in background
I need to identify every time the user clicks the mouse. My VB app is running in background, under WINNT4 as a kind of daemon. I'm not interested in diferentiating what kind of click it is (right/left click, double-click, etc).
I'm using VB5, but VB6 will do too.
Any ideas?
Thanks.

Dear Maquiavelo,
you can use the Doevents,
I use it for checking whether some key has been pressed while a process is going on. For example :
dim flag as Boolean
dim i as Integer
flag=true
while flag
i = i + 1
DoEvents
wend
***** This program will detect keypress when control has entered while loop.As you can see that while loop is an infinite loop.
hope this helps you.
regards

Thanks Vindevogel: where can I get those tools for free? I've been reading Dan Appleman's book (WINAPI32 Guide or something like that), and the book has a demo version of the controls; but I have to distribute the project because it is a university exam.
And I don't know if it would work, because I'd have to check every window open in the system. Do U think this would be fast enough?
This is Simple solution :
1 - Put a Timer Control as Timer1 into your form and set the Interval property to 300;
2 - Paste the next code into your form declarations :
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
Dim NumClicks As Long 'Number of Clicks
3 - Paste the timer code :
Private Sub Timer1_Timer()
Dim Lbutton As Integer
Dim Mbutton As Integer
Dim Rbutton As Integer
Lbutton = GetAsyncKeyState(1&)
Mbutton = GetAsyncKeyState(4&)
Rbutton = GetAsyncKeyState(2&)
If Lbutton Or Mbutton Or Rbutton Then
If Lbutton <> -32768 And Mbutton <> -32768 And Rbutton <> -32768 Then
NumClicks = NumClicks + 1
End If
End If
End Sub
4 - Turn the timer enable and enjoy !
