if i do not need to evaluate all the expressions, am i right to say that there are benefits and no disadvantages of using AndAlso compared to using And
example:
if a=b And f=g And y=k
can be better done with:
if a=b AndAlso f=g AndAlso y=k
I have this code and it evaluates to false instead of a string. All its doing is building a string.

This is probably a basic question, but I have never used this syntax before. Can someone tell me in detail how this expression evaluates to true? [Assuming IsOdd is a boolean type].

I am using a class to check for certain words in my application to prevent SQL Injection. In the class, there is a for loop that tries to match a specific word with the words from a blacklist. If there is a match, I must redirect to the system's error page. However, when a match is found and I try to redirect, I keep getting the error "Unable to evaluate expression."

So 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?

I 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?
I am new to VB.NET and I keep telling myself there must be a better way to do what I need to do several times a day which is look into a list and see if that one field is set to true anywhere in that list.

View 1 RepliesI'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?!
I am able to hover over a variable and see it's current value, and I can even "Watch" an expression (such as the conditional), but the tutorial claims[code]...
