Evaluate 3 Conditions In An If Statement?
Dec 9, 2011So I am trying to evaluate 3 conditions in an if statement. Its not working how I would assume it should. I basically want to do this:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 And (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
If I write it in that manner it gives inconsistent results. If I workaround by writing it this way it works perfectly:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 Then
If (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
Endif
What is the proper way to do this with only one if statement?

Can't Parse - Unable To Evaluate Expression
Feb 10, 2009I have this line in some
Integer.TryParse(ThisRow.Item("DatumID").ToString, n)
ThisRow is a datarow. The "DatumID" in this case happens to be an empty string, but is not Null. When I break on this line, and try to evaluate it by highlighting it and pressing Shift+F9, I get the message "Unable to evaluate expression". Interestingly, it is actually evaluating correctly (since the item holds an empty string, TryParse returns False).
I have tested this in every way I could think of (mostly I thought I had left out a parenthesis in my expression, but that wasn't true). So why won't that expression evaluate when tested, even though it is actually working correctly?

View 1 RepliesEvaluate Conditionals By Hovering In Debug?
Jan 10, 2011I'm reading a tutorial provided by someone at my university, and it claims that if you're debugging a VB.NET program, you can hover over a conditional (e.g. "Age > 13") and it will be evaluated. However, in VB 2010 Express, I am not seeing this functionality.
I believe the tutorial may have been written for a previous version of VB.NET, so I was wondering if anyone could tell me if this used to work and has been removed, or whether it has never existed?!
