Mouse Movement

How do you detect the mouses movement with out using a mouse event in a form or any other thing in the tool bar in vb?

You can use the GetCursorPos API function to get the cursor position from anywhere on the screen (not just over your form or controls).

Here is a sample project:

1. Start a new VB project
2. Add a standard module (Module1)
3. Add 2 labels to your form (Label1 and Label2)
4. Add a timer to your form (Timer1)
5. Set the timer Interval property to 1
6. Paste the first section of code into the Module
7. Paste the second section of code into the form's code window
8. Run the project and move the mouse around!

Here is the code for the Module:

Code:

---

Option Explicit

Type POINTAPI
    x As Long
    y As Long
End Type

Declare Function GetCursorPos Lib "user32" _
    (lpPoint As POINTAPI) As Long

---

Here is the code for the form's code window:

Code:

---

Option Explicit

Private Sub Form_Load()
    'This just sets up the form and controls (not really necessary)
    With Me
        .Caption = "Cursor Position"
        .Width = 2750
        .Height = 1500
        .left = (Screen.Width - .Width) / 2
        .top = (Screen.Height - .Height) / 2
    End With
   
    With Label1
        .Alignment = vbCenter
        .Width = 1750
        .Height = 300
        .left = (Me.ScaleWidth - .Width) / 2
        .top = 100
    End With
   
    With Label2
        .Alignment = vbCenter
        .Width = Label1.Width
        .Height = Label1.Height
        .left = Label1.left
        .top = Label1.top + Label1.Height + 100
    End With
End Sub

Private Sub Timer1_Timer()
    'This is the real meat of the program...not too difficult!
    Dim CursorPos As POINTAPI
   
    GetCursorPos CursorPos    'Assigns cursor's x and y to CursorPos
   
    Label1 = "Cursor X = " & CursorPos.x
    Label2 = "Cursor Y = " & CursorPos.y
End Sub

Hope that helps!
