how to change mouse speed?

Change mouse speed from setting the value in a textbox (textbox1), then clicking a button to change it (set it).

Add this to the form:

Code:

---

Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" _
    (ByVal uAction As Integer, ByVal uParam As Integer, ByRef lpvParam As Object, ByVal fuWinIni As Integer) As Integer
    Const SPI_SETMOUSESPEED As Integer = 113

---

and put this in the button's Click sub:

Code:

---

        SystemParametersInfo(SPI_SETMOUSESPEED, 0, Integer.Parse(TextBox1.Text), 0)

---

The maximum value for the speed is 20.

I'd be very careful about changing system-wide settings like the mouse speed unless your program is specifically designed to do that.

Nothing a user hates more than a program that messes around with their windows settings if they don't realise thats whats happening.

Point taken. Thanks, Paul. BB
