I hope someone can help me. I develop my first C# WPF Program and I need an input control for IP Address. To my big surprise there isn't a control for this which I think is pretty strange. In C++ I have something like that.

Okay so far I have read I could use a masked textbox from the extended wpf toolkit. But I have 2 problems with that:

First of all when I use a mask like 000.000.000.000 and someone wants to enter an address like 192.168.1.1 I would get 192.168.001.001 But I don't want to see leading zeros

the second problem is that someone could enter an address like 500.300.400.800. How can I handle this?

Thank you for the link but that's what I did the entire day yesterday but I found no page that answered my 2 questions. Either the links weren't available anymore or they just said that you should use masked textboxes. But non of them has explained how to handle my two problems with the masked text boxes

I also found a dll that offered an IP Address control but I couldn't change the font size for example for the control at all so I can't use it either

Try posting your question in the WPF forum, you may get a better answer.

Don't you see that an IPv4 address consists of 4 bytes?
Now write a value converter between string and IpAddress which handles that formatting.
That can be based on the following snippet showing both conversions:

IPAddress address = IPAddress.Parse("192.168.1.1");
byte[] bytes = address.GetAddressBytes();
string formatted = $"{bytes[0]:D3}.{bytes[1]:D3}.{bytes[2]:D3}.{bytes[3]:D3}";

Why not just use a normal TextBox control, combined with IPAddress.TryParse[^] to parse the input?

The problem with the old IP address control is that it's limited to IPv4 addresses. If your application ever needs to deal with IPv6 addresses, that control won't work.

Really? That's a not-so-commonly used control so I'm not surprised it doesn't exist.

On the other hand, up until about seven years ago, WPF didn't have a data grid. Now THAT was a surprise!

System.ItDidntWorkException: Something didn't work as expected.

Why It displays error?

I have created SQL store procedure.

 CREATE PROCEDURE spGetMiti (
@engdate varchar(10)
) with encryption AS
BEGIN
   DECLARE @RC int
   DECLARE @RomanDate DATETIME
   DECLARE @PrnLine nvarchar (4000)

   EXEC @RC = [HRDB].[dbo].[s_GetNepaliDate] @engdate, @RomanDate OUTPUT
   SELECT @PrnLine = isnull(CONVERT(nvarchar, @RomanDate, 111), '')
   SELECT @PrnLine [Tarikh]
 END

it displays in correct result after executing store procedure

EXEC spGetMiti '1978/02/03'

Tarikh > 2035/10/21

IN c#, class MtCommom

private string _engdate = string.Empty;
        public string Engdate
        {
            get { return _engdate; }
            set {
                if (value.Length < 10)
                {
                    throw new Exception("Correct date is required");
                } _engdate = value;
            }
        }

        public DataTable GetMiti()
        {
            SqlParameter[] param = new SqlParameter[]
            {
                new SqlParameter("@engdate", _engdate)
            };
            return DAO.GetTable("spGetMiti", null);
        }

in Button Press

MtCommon mtcom = new MtCommon();
     mtxtDOB.Text = string.Empty;
     mtcom.Engdate = mtxtEngDate.Text;
     DataTable dt = mtcom.GetMiti();
     mtxtDOB.Text = dt.Rows[0]["Tarikh"].ToString();

Error Displays
"Procedure or function 'spGetMiti' expects parameter '@engdate', which was not supplied."

public DataTable GetMiti()
{
    SqlParameter[] param = new SqlParameter[]
    {
        new SqlParameter("@engdate", _engdate)
    };
    return DAO.GetTable("spGetMiti", null);
}

In the above code you create an array of SqlParameter values, and add one labelled @engdate. However, when you call the stored procedure, I do not see that the parameter array is being passed to it.

CREATE PROCEDURE spGetMiti (
@engdate varchar(10)
) with encryption AS
BEGIN
DECLARE @RC int
DECLARE @RomanDate DATETIME
DECLARE @PrnLine nvarchar (4000)

EXEC @RC = [HRDB].[dbo].[s_GetNepaliDate] @engdate, @RomanDate OUTPUT
SELECT @PrnLine = isnull(CONVERT(nvarchar, @RomanDate, 111), '')
SELECT @PrnLine [Tarikh]
END

I think, there is a parameter "@engdate". Isn't it parameter?

Richard MacCutchan31-Aug-17 21:46

Yes, but you never send the parameter when you call the SP.

Dear Sir,

Thank you for your response and pointing on parameter. I focused on parameter and

I found out the error in my code

public DataTable GetMiti()
        {
            SqlParameter[] param = new SqlParameter[]
            {
                new SqlParameter("@engdate", _engdate)
            };
            return DAO.GetTable("spGetMiti", null);
        }

return DAO.GetTable("spGetMiti", null);

I corrected it

return DAO.GetTable("spGetMiti", param);
