how to handle error while using webCalmanager.calculate
posted

Hi

I have a question about how to check the formula string is in the corrected format that the method "calculate" can calculate it.

for example, if i put the formula string like 

answer = uc1.Calculate("+").ToDecimal()           '''''''''condition 1

instead of     

answer = uc1.Calculate("2+3").ToDecimal().       '''''''''condition 2

how can i set answer = 0 on event like condition1

    Hi,

    I'm not sure if you have already figured this out, but since there is no response from anyone (in almost a year), and your question actually helped me solve an issue I was having, I thought I would try an answer your question, if not to help you, to maybe help someone else who has this issue in the future.

    I solved this by wrapping your code in a try{}..catch{} function, like this:

    try

    {

        answer = uc1.Calculate("+").ToDecimal();

    }

    catch (Exception ex)

    {

        answer = 0;

    }

    I hope this help you or anyone else who comes across this issue in the future.
