firing numericupdown event from another function

firing numericupdown event from another function

  There's a simpler solution to your problem: just make a 'Static' variable inside the ValueChanged Sub. The static variable will retain its value so the next time you enter the eventsub, you can compare the current value against the static variable to see what the change was.

  Hi,

   I had to re-read as i started thinking about mouse event arguments. As in mouse button up or down.

  To FIRE from another function use.>>

  NumericUpDown1.UpButton() ' or

  NumericUpDown1.DownButton()

   

  Anyway the following code doesn't work in the Value_Changed Sub for some unknown reason in that event it takes two clicks on a control arrow to change the textbox1 content. [EDIT : ] I've just realised the Value_Changed event is fired mostly when it is changed manually ( not with the arrow buttons ) as in Text_Changed for a textBox.

  Dim prevValue As Double = 0

  Private Sub NumericUpDown1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles NumericUpDown1.MouseDown

  Dim myNum As Double

  myNum = CDbl(NumericUpDown1.Text)

  If myNum > prevValue Then

  TextBox1.Text = "Number went up!!"

  ElseIf myNum < prevValue Then

  TextBox1.Text = "Number went down!!"

  ElseIf myNum = prevValue Then

  'You'll see this message only when you reach the MAXIMUM

  'or MINIMUM value set in the control after another click of your mouse too.

  TextBox1.Text = "Number in the control hasn't changed!!"

  End If

  prevValue = CDbl(NumericUpDown1.Text)

  End Sub

  Hi,

  Do you also need to know when the Maximum or Minimum values are reached and if the user is still clicking the mouse
