Hi,

This is the code.

CODE 1: cmd.Parameters.Add("@RateCenterID", OleDbType.Integer).Value = Convert.ToInt32(ratecenterid.Text);

CODE 2: cmd.Parameters.Add("@QuantityThreshold", OleDbType.Integer).Value = Convert.ToIn32(quantityThreshold.Text);

I get the following error in the **CODE 2** but not in CODE 1

Error: **Value was either too large or too small for an Int32.**

kindly help me

Regards,
Arjun

Solution 1

Use int.TryParse() method

C#

int theResult = 0;
            if (theValue == null || Convert.IsDBNull(theValue) || !int.TryParse(theValue.ToString(), out theResult))
                theResult = 0;
            return theResult;

Solution 2

OleDbType.Integer is a 16-bit integer and not 32-bit. You would need to use LongInteger instead. The value entered in quantityThreshold.Text is probably larger than 32767 (or below -32768)

Good luck!
