Can I do calculations in text boxes? Suppose the text property of a textbox is "2*4+5" and I want the result in an integer type variable iResult so that iResult = 13. So whenever I call iResult it will give me the integer 13, not the string "2*4+5".

Suppose, this is the code I have

for x = 1 to 10
y = text1.text
print x
next x

Now I will enter "2 * x + 5" in the textbox and the output would be 7,9,11...
