Greeting everyone! Thank you in advance for your help. Here is my problem. I am trying to code a simple weather tracker program in VB Express. I have it built, but it always throws an exception in my 'ExtractTemperature' Function. Let me post that function:
[align=center]Private Function ExtractTemperature() As Double
If (lblTemperatureCurrent.Text.Length = 0) Then
Return Integer.MinValue
Else
' Returning only the number portion ignoring the
' degree F
Return CDbl(lblTemperatureCurrent.Text.Substring(0, _
lblTemperatureCurrent.Text.IndexOf("º")))
End If
End Function[/align]
The 'lblTemperatureCurrent.Text is supposed to be in the form of an integer followed by the degree symbol followed by F. The function should strip the degree symbol and F off the integer, returning just the integer value. I am under the impression that the lblTemperatureCurrent.Text.IndexOf function is returning a -1 which is throwing the exception. How can I get the value of lblTemperatureCurrent.Text at that point so I can tell if it is a problem with the value of the variable or the fault of the function itself? Again, thank you for your help.
