Is there a way to get a list of required keys or variables for a formula in CalcQuick. When you call the ParseAndCompute, it will only cause an error about the first key.

e.g.
Dim clc As New CalcQuick(True)
clc("KeyOne") = 1
clc("KeyTwo") = 2
clc("KeyThree") = 3
Result = clc.ParseAndCompute("Key1 + Key2 + Key3")

will return the error "Unknown Key: KeyOne".

But I would like to get either a list off all the variables in the formula so i can check them, or an error for each missing key?

Hi Tom,

Thank you for your interest in Syncfusion products.

The named values specified through the calculate engine has to be retrieved in the formula through the square braces. Also the name does not seems to be the name provided in the formula.

Please refer the code below:
Result = clc.ParseAndCompute("[Key1] + [Key2] + [Key3]")

Let me know if you have any concern.

Just to clarify I want it to identify all the missing keys in the formula not just the first one:

Dim clc As New CalcQuick(True)
clc("KeyApple") = 1
clc("KeyBanana") = 2
clc("KeyCarrot") = 3
Result = clc.ParseAndCompute("[KeyZam] + [KeyYogurt] + [KeyXray]")


Would generate an error of "Missing KEYS KeyZam, KeyYogurt and KeyXRay"

Also is there a way of clearing out any keys in a calcquick object
