Hi, You cant evaluate an expression like this directly in .Net. You have to create your own function using some algorithm like Polish Notation to evaluate arithmetic expressions. I have submitted an article for this just follow this link... this is very poor explanation but this code will help you alot (I think)... :-O Evaluate Arithmetic Expression using Polish Notation Login in VB.NET 2005[^]

hi, i cannot convert string to int, dim strExt as string strExt = 10 + 20 + (iif(20 > 30), 40, 50) + 50 int complexsum = strExt string str = complexsum.ToString(); its giving convertion error i tried to convert also... Note : This "10 + 20 + (iif(20 > 30), 40, 50) + 50" Expression is comming from database , so i copid to string then am trying to eveluate.
