Re: How to Implement Private methods in an Interface

You can't it is against the language syntax because, as DaveyMnn said, it wouldn't make sense. Interfaces are there to define members that are publically available in the class.

If you want to protect code from external use it cannot be part of the Interface. You can however call private or protected methods (which cannot be in the Interface) from your public ones (which can).

Perhaps you should sit back and reflect on the word "interface".

it shares 5 letters with private, and only 2 with public.

That's ancient Sumatran - it means only public methods. It comes from a time when sacrifices were common place and there was a need to appease the gods by performing the sacrifice in public. They tried it in private for a while, but the populace started to suspect that all the pigs they were bringing to be sacrificed were just ending up as a really great luau.

What about an abstract base class instead of an interface? There you can use something like protected abstract void MyMethod();

Is the server running?

If yes then you have a configuration/connection problem and nothing else.

If you want to connect from a different box then you must use the configuration tool to set that up.

Uninstall it, install it, install SQL Server SP3, and it should run the provisioning tool when you're done that gives your user the correct permissions.

Hi CanI

Before I also had the same problem as you, and the solution was to install SQL Server 2005 SP3.

One more thing, do not forget to run the SQL Server, type in the search box "service" and will open a window where to look for "SQL Server (SQLEXPRESS)", right click and start.

It's all

Generate files using Macros in Excel

Hi,
Hope this is the right place to post this issue. If not, please let me know the correct place.
I've an excel sheet, where I have both table structure and table data. I need to write a macro which generates two different files (one for create statement and one for insert statement). To give more details,

ExcelSheet1
SNO COLUMN Data Type Remarks
1 Award_Id integer PK
2 AAI_ID Integer
3 Award_Short_Name varchar Abbreviated Award Name

AWARD_ID AAI_ID AWARD_SHORT_NAME
3000 2001 B.Tech
3001 2003 B.Tech
3002 2001 B.Tech

The macro for this excel sheet should generate, the below files

1. DEMAT_REQUEST.dat
INSERT INTO DEMAT_REQUEST(Award_Id, AAI_ID, Award_Short_Name)
VALUES (3000,2001,'B.Tech');

INSERT INTO DEMAT_REQUEST(Award_Id, AAI_ID, Award_Short_Name)
VALUES (3001,2003,'B.Tech');

INSERT INTO DEMAT_REQUEST(Award_Id, AAI_ID, Award_Short_Name)
VALUES (3002,2001,'B.Tech');

2. DEMAT_REQUEST.sql

CREATE TABLE TXN_DEMAT_REQUEST
(
Award_Id INTEGER(20) NOT NULL,
AAI_ID INTEGER(10) NOT NULL,
Award_Short_Name VARCHAR(10) NOT NULL
PRIMARY KEY(Award_Id)
};

Thanks alot in advance

The convert class can also be used for this:

Convert.ToString(number, base)

where base can be 2 (binary), 10 (decimal) or 16 (hexadecimal).

Thanks for your reply.

If you just convert it as you have shown it Eliminates the "0".
Say for example you have to convert 0000111111111000 into Hex.So it will show FF8 instead 0FF8
Well I was able to over come that by doing following:

string MyBinary = "0000111111111000";
string MyHex = String.Format("{0:X4}", Convert.ToInt32(MyBinary, 2));

When I need padding I use the string.PadLeft method. A couple of functions like this are all that's needed.

public static string ToHexString(int value)
{
    return ToHexString(value, 0);
}
public static string ToHexString(int value, int bytes)
{
    string result = Convert.ToString(value, 16);
    if (bytes > 0)
        result = result.PadLeft(bytes * 2, '0');
    return result;
}

int b = 15;
string s=b.ToString("X8");

I advice to always specify the width you want; padding zeroes will be prefixed when necessary.

Have you got a firewall enabled?
Attach snippets of your client and server code so we can see what you're doing.

check your server call back function is correct or not..,
i think that is the problem, that's way you are able the receive the data for very first time of each new client.
