How to detect unused variables?

Hello experts.
I have 2 questions:

1: I remember when I compile C programs using cc compiler it tells me whether I have un-used variables.

Is there a similar thing in VB?

2: I sometimes declare variables without a viariable type ie..

dim aString
dim aInt


which will set the variables to type Variant.

When i do this, it would be by mistake, is there a way to get the compiler to tell me this?


Thanks


Kaiser

See the tools here. They are free and Project Analyzer has the feature of detecting unused variables and mismatches like your example. http://www.aivosto.com/visdev/

Thanks for the answer. I checked out the website and
it was good. But the only had solutions to Q1.

If you dont mind I would like to keep this question open to see if people have suggestions for Q2.


If there is nothing else, then you could have the points.

Q2. There is no way a compiler can do this. Compiler will check for the syntax and as per the syntax it is a valid. So it will continue without any problem.

You can take a precaution using
DefBool DefByte DefInt DefLng DefCur
DefSng DefDbl DefDec DefDate DefStr ...

May be you cam write an add-in to check for these kind of declarations

Sorry about that, that websites software did have that feature.

If you want to put in another answer, then I can forward you the points.

It was just a feature that was hidden, you had to pop up the options thats all.

Thaks again.
