try the following:

boolean check = false;   // declare variable *outside* try/catch blocks
try
{
   check = false;
}
catch (the exception)
{
}
try
{
      if (check ==true)
      {

i'm sorry, i should have also mentioned that the boolean check = false; --> is in the catch block of the first try catch blocks.

yes, I'm saying you need to move it *outside* so its visibale in both blocks
See the code I posted above

-->>i understand that, however, if a catch is caught, i need the boolean to be false, otherwise true. so to my knowledge, i believe this will not work if i have it outside of the catch, as the var will always be false.

-->>HAHA,

-->>:P.....

-->>I started to think.. and logically thought of a for loop outside of all of this try catch blocks, then implemented the

-->>break statement when a catch was caused... making the loop break... the loop is only in one iteration...


:P


-->>Practical Method, i'd say hey?

-->>Thanks Guys...

What CEHJ suggested would not work. You were setting the flag in the wrong place.
What I suggested was not the same as what CEHJ stated, a split is not necessary.

Try his suggestion if you like, check will never get set :)
