Question

I have used the store procedure in MS-Sql for inserting for particular page it is working fine but I also need the same store procedure for other page it is finding me the error.

protected void btnsubmitt_Click(object sender, EventArgs e)
{
    ArrayList arParameters = ReturnParameter();
    DataSet dsInsertProfile = objadmin.GetGridData(arParameters,                    objconstant.sSP_INSERT_PROFILE);

    if (int.Parse(dsInsertProfile.Tables[0].Rows[0].ItemArray[0].ToString()) == 0)
    {
        pnlProfile.Visible = false;
        pnlThank.Visible = true;
        lblThank.Text = "Your profile have been successfully saved.";
    }

    else
    {
        lblThank.Text = "Your profile is not saved, please try again later.";
    }

}
public ArrayList ReturnParameter()
{
    Int64 email = Convert.ToInt64(txtemail.Text.ToString());
    ArrayList arSample = new ArrayList();
    Object[] c_email_id = new Object[3] { "@strEmailID", "varchar", email};
     arSample.Add(c_email_id);
     return arSample;
}
  public DataSet GetGridData(ArrayList dbArray, string sSpName)
    {
        DataSet dsDataSet = new DataSet();
        dsDataSet = datamanager.GetGridData(dbArray, sSpName);
        return dsDataSet;
    }
    public static DataSet GetGridData(ArrayList dbArray, string sSpName)
    {
        DataSet dsDataSet = new DataSet();
        SqlConnection cn = createConnection();
        SqlCommand cmd = new SqlCommand();
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.CommandText = sSpName;

        object objPrMtrName;
        object objSqlType;
        object objPrMtrVal;
        int i;
        for (i = 0; i < dbArray.Count; i++)
        {
            objPrMtrName = ((object[])(dbArray[i]))[0];
            objSqlType = ((object[])(dbArray[i]))[1];
            objPrMtrVal = ((object[])(dbArray[i]))[2];
            cmd.Parameters.Add(objPrMtrName.ToString(), GetSqlDataType(objSqlType.ToString())).Value = objPrMtrVal;
        }
        cmd.Connection = cn;
        try
        {
            SqlDataAdapter adp = new SqlDataAdapter(cmd);
            adp.Fill(dsDataSet);
            return dsDataSet;
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            cn.Close();
            cn.Dispose();
        }
    }

Mystore procedure

ALTER Procedure [dbo].[spInsert_profile]
(  @strEmailID varchar(200)

)
 AS
BEGIN
    DECLARE @intEmail INT
SET @intEmail = (SELECT COUNT(*) FROM gdt_Users WHERE [c_email_id]=@strEmailID)        
IF @intEmail = 0
 BEGIN

       Insert into gdt_Users([c_email_id],[d_modified_dttm],[d_created_dttm])values(@strEmailID,GETDATE(),GETDATE())

 SELECT @intEmail
  END
ELSE
    BEGIN
        SELECT @intEmail

    END
END

Here, I was facing a problem. It was throwing an exception

ERROR: Failed to convert parameter value from string to Int64 

So, I’ve add this code

Int64 email = Convert.ToInt64(txtemail.Text.ToString());

in arraylist returnparameter() method. Then, it threw that exception

ERROR: Input string was not in correct format

How can I solve this? Can you help me?

Answer 1

In your code I can find Convert.ToInt64 only at one place which is

Int64 email = Convert.ToInt64(txtemail.Text.ToString());

You would not be passing valid number to Convert.ToInt64( as txtemail will have string not a number. You should give a number in txtemail or use the correct textbox for converting the string to int64.

Keep in mind Convert.ToInt64( converts string to number only if the
string is number.
