Mouse Up/Down [RESOLVED]

i am trying to figure out how to make a program to detect if a left or right mouse button has been pressed using a VB6 application that is hidden. does anyone know if this is even possible using vb6? im new at programming so im not sure where to even start. thanks guys

Not sure what you mean by "hidden application", but here's one in the code itself:

VB Code:

Private Sub Form1_MouseDown() 'don't remember what goes in here
 
   If vbRightButton Then
      'whatever happens if right button is hit
   ElseIf vbLeftButton Then
      'whatever happens if left button is hit
   Else
      'whatever happens if middle button is hit
   End If
 
End Sub

You can use GetAsyncKeyState to check wheather or not the mouse is down...

VB Code:

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
 
Private Sub Timer1_Timer()
Dim Ret As Integer
Ret = GetAsyncKeyState(1) 'vbKeyLButton = 1
MsgBox Ret
End Sub

If it is less than 1 the mouse button is down..

thanks guys! what i mean by hidden is like if the application is minimized and another is in focus

Thats what my code does...look.. you'll have to press stop in the VB IDE to stop the program..

thats exactly what i have been looking for! thanks soo much! now im wondering... is there anyway that it will record only when you press the middle mouse button?

Change the GetAsyncKeyState(1) to GetAsyncKeyState(4)

Left Mouse Button = 1
Middle Mouse Button = 4
Right Mouse Button = 2

:wave:

hmmm... i changed it to this:

Code:

---

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer

Dim file_contents As String

Private Sub Timer1_Timer()
Dim Ret As Integer
Ret = GetAsyncKeyState(1) 'vbKeyLButton = 1
If Ret < 1 Then
    Text1.Text = Text1.Text + 1
   
   
   
End If
End Sub

---

i added a text box to show every time it is clicked but for some reason the text box just keep going up whether i click or not.. i then changed it to If Ret = 1 Then and with that you have to click the mouse a few times before it adds one to the text. anyone know whats goin on?

Its the Timer's Interval. You need to try and get it to the right one. It has to be close to the human reaction time for clicking a mouse. You just need to experiment with it, changing the Timer's interval property to lower values.

EDIT:
And you should keep it

VB Code:

If Ret < 1 Then

If it is < 1 it means the mouse is DOWN. If it is 1, it means the mouse is UP...

i dont understand what you mean.. using that code i was thinking that everytime you click it would add +1.. using the timer and when Ret < 1 it only adds +1 once the timer runs down

Ok, this is what the code does.

Once (1 time) a second, the program checks if the Mouse is DOWN (Ret < 1). If it IS down, it writes to the file (your program adds to a textbox). If it ISN'T down (Ret = 1) then it does nothing. The timer will continue to execute that code Once (1 time) per second, until the program is closed..

EDIT:
Also, the Mouse MUST be down at the exact time the timer executes that code, which is why you need to put it to a smaller value than Once a second.

ok i understand it now.. thank you! now im wondering... is there a way to make the timer less than 1? i have it so that when you hold down the button it adds +1 each time the timer counts down from 1, but i want it a faster.. i know i didnt explain it very well :)

what fraction of a second is 1 in the vb timer?

1000 = 1 second

1 = 1/1000th of a second..


Why do you need it faster than that?
