given

string input = "01010101";

you should get the output as the first two chars with

input.Substring(0, 2);

In general look at the Substring[^]

Rad Ajax manager and rowclick event

While you've been given fair advice on how to do this, I must urge you to consider the edge cases in your code. What happens if your user enters 1? Substring(0,2) will fail. What happens if they don't enter anything at all? What if they enter " 1"? Please ensure that your code copes with cases like these:

public void FilterDepartments(string input)
{
  if (string.IsNullOrEmpty(input)) return;
  string filter = input.Trim(); // Remove trailing/leading spaces.
  if (filter.Length > 1)
    filter = filter.Substring(0, 2);
  // Now use the filter.
}

Hi,

i need to create a dynamic row for HTML table in my asp.net application on every button click, i have tried many ways, but most of the cases, viewstate is not maintaining(for dynamically created row), and meanwhile i need to save these rows into database.

Please help me, if anybody knows...

Thanks in advance

Convert String to Int

Hi,
Please let me know how can i convert

string x="10000000000" to int...

i tried Convert.Int64 but im getting exception that number is too long or too short to store value in INt32..

Peace ON26-May-10 0:32

I think the number is exceeding the limit of Int32 or Int64

try following code for successfully converting your string to
number

If number >= Int32.MinValue And number <= Int32.MaxValue Then
      newNumber = Convert.ToInt32(number)
      Console.WriteLine("Successfully converted {0} to an Int32.", _
                        newNumber)
   Else
      Console.WriteLine("Unable to convert {0} to an Int32.", number)
   End If

You can use the same logic for Int64.

i think maxvalue for Int64 is 9,223,372,036,854,775,808 which is greater than 10000000000

The error says number is too long or too short to store value in Int32..

So I think you are trying with Int32.

Try using the int64 parser

Int64.Parse(string input)

"Was" not working or "is" not working?

The above mentioned solution (int64 + parse) works fine.

Tested:

string test = "10000000000";

System.Int64 int64 = Int64.Parse(test);

and it is totally ok.

When you say "it" says the file is corrupted we have no idea what "it" is. Is it media player? Is it iTunes? We also don't know what you are doing after retrieving the data from the database. Are you streaming to a browser? Are you saving to a file?
