Conversion from string "" to type 'Integer' is not valid.

[Syranthrax]

I know this question has been addressed, however none of the suggested fixes are resolving the issue.

This one causes the error (initial value of txtPoint.Text is 35):

 
Private Sub nudPoints_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles nudPoints.ValueChanged
       Dim points As Integer = CInt(txtPoint.Text) + nudPoints.Value + nudMiscPoints.Value
      txtPointsTotal.Text = points
  End Sub
 
 
This one works fine (initial value of txtAppraise.Text is 0):
 
Private Sub nudMiscAppraise_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles nudMiscAppraise.ValueChanged
    Dim total As Integer = CInt(txtAppraise.Text) + nudAppraise.Value + nudMiscAppraise.Value
    txtAppraiseTotal.Text = total
  End Sub
 

Neither have any trailing spaces, special characters, or letters. I have tried scrapping the problematic Sub and rebuilding it using different variables and it still generates the error. My limited training has got me at a loss. Any help would be greatly appreciated.

Use Integer.Parse() instead of the old VB methods

Better yet, try using the Integer.TryPars e() method.

Private Sub nudPoints_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles nudPoints.ValueChanged
Dim points As Integer = Int32.Parse(txtPoint.Text) + nudPoints.Value + nudMiscPoints.Value
txtPointsTotal.Text = points
End Sub

CsharpChico, what is your code supposed to be showing us?

Right now, if you try to run the code you will get a warning (maybe an error if your Visual Studio's settings are high enough) because you are trying to assign an integer to a Text property (which expects a string).
