GUIDs in C# / SQL

26. June 2009 15:37

C# SQL Server Code Snippets 

GUID pronounced as goo'id - Globally unique identifier is a 128-bit integer that can be used to uniquely identify something. If you want to identify the large collection of data GUID is the best approach in my view. Also you can use the autoincremental integer to identify records, this is the basic approach programmer's use.

GUID method can be found under the System namespace and it also provides some overloads. Here is how we can use the GUID overloads:

System.Guid.NewGuid().ToString();    //c93ded50-7cce-4f3a-b8aa-5a1a34d80b14
System.Guid.NewGuid().ToString("N"); //636bdfd2bbc541229fbc6b869995ce6f
System.Guid.NewGuid().ToString("D"); //45e602b6-0904-47ac-a764-a5522f56f40f
System.Guid.NewGuid().ToString("B"); //{68f55508-f72c-4a38-b96b-f493c3c5adb9}
System.Guid.NewGuid().ToString("P"); //(1c2e52a7-e384-445e-b80a-e8704c6ecbd6)

To create GUID in SQL Server use the simple select statement:

SELECT NEWID()

Backup/Restore SQL database using C#

21. June 2009 15:59

C# SQL Server Utils 

Microsoft’s .NET framework provides the flexibility to Backup and Restore SQL server database. A few lines to populate the names of all the server instances, create backups and then restore the backups. The application what you see here is a part of an application, so when you create backups and restore it will use the same path hardcoded in the code itself. You can change the way you like it.


Namespace you need to add:  

using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;
using System.IO;

I am not going to write on and on and just make it going boring, so it's better just download the code and check the comments, they are one liners, but clears everything.

Set the default printer for printing programatically

16. June 2009 15:17

C# Code Snippets 

You need to print the document but you don't want to go to control panel or printer and faxes options and just want to get it changed automatically. You can even set the shared local network printer with this code.

Just with the code you can override the system settings and change the default printer for your system.

You need to use the namespace so in order to use the DLLImport attribute.

using System.Runtime.Interopservices;
//Set default printer to the one available with your system or network.
[DllImport("Winspool.drv")]
private static extern bool SetDefaultPrinter(string printerName);

Now on button click or on form load just change the printer you want to use while printing and then change it back to the one before.

//Set the default printer. I have set it as my Adobe PDF printer
SetDefaultPrinter("Adobe PDF");
