Regular expression calculation.

Vasanth

I need a code to evaluate the regular expression without using any build in function.

If i enter the following "2*5*(2+5)" in the text box, it should automatically evaluate and display the result in the other text box.

Thanks in advance.

Your question is not clear. Regular expression are meant for matching patters and not calculations. Explain clearly what you need

Oh sorry for that.

I need to calculate the expression that is given in the text box.

If i enter "2+(2*10)", it should calculate the following expression and display the result.

I can give any expression even invalid expression such as "2*+4+(1+2".

If the given ecpression is invalid then it should display it is invalid.

Hope you understand my question.

If not please let me know.
