Put your code here.

Solution 1

Check against 0L instead of just 0.
That way, the zero is interpreted as of type long itself and therefore there should be no type mismatch between an integer and a long anymore.

Still Showing

Operator '&&' cannot be applied to operands of type 'string' and 'long'... :(

Where does that 'string' come from?
In your question, you're talking about 'long' and 'int'. So if this solution doesn't work for you, do as Rajeshkumar Ramasamy told you and post your code.

That's what the "Improve question" link is for. Use it.

Solution 2

Solved Myself with following... :)

C#

if ((variable1== null || variable1== "0") && (variable2== null || variable2== "0") && (variable3== null || variable3== "0"))
      {
          Response.Write("You have not selected any checkbox!!!");

      }

You have tagged your question C++ and C#, but this code looks more like Javascript.

<quote>long variables...<quote>not supported for int & long
Neither an int nor a long can ever be null. Nor can any of these be tested for equality against a string literal.

Sort your question out (use the "Improve question" link for that).
