1) Installation Process
a) Go to the following web site
http://go-mono.com/sources-stable/
b) dowanload mono-1.2.5.2.tar.bz2
c) go on terminal (command prompt for windows user )
d) login to root user
e) move mono-1.2.5.2.tar.bz2 to /usr/local/src by using following code
mv mono-1.2.5.2.tar.bz /usr/local/src
f) also move to src directory
cd /usr/local/src
g) type the following command to untar ( ie unzip for windows user ) the package
tar -xjf mono-1.2.5.2.tar.bz2
a new directory is created named " mono-1.2.5.2 "
h) move to that directory and type
./configure (dot then back forward slash )
after the configeratin will finish type

Learn how to register an assembly in the GAC.

1) Create an assembly key file Use the sn.exe tool to create a key file: sn -k StrongNameFile.snk If your path environment variables aren't set, you'll have to go to the C:\Program Files\Microsoft.NET\FrameworkSDK\Bin\ directory to run sn.exe) The filename "StrongNameFile.snk" can be any name you want. 2) Edit your assembly Now you have to add a tag which will link your assembly key to the assembly: using System.Reflection; [assembly:AssemblyKeyFile("StrongNameFile.snk")] Normally this is done in the utility AssemblyInfo.cs (vb) file. 3)Add your assembly to the GAC gacutil /i AssemblyFileName.dll To uninstall this assembly from the GAC, use the command: gacutil /u AssemblyFileName 4) (Opional) Add your assembly to machine.config Locate the <assemblies> tag (for web apps,under <configuration>/<system.web>/<compilation>/<compilers>/<assemblies>) Between the <assemblies> tags, enter: <add assembly="AssemblyFileName, Version=0.0.0.0, Culture=neutral, PublicKeyToken=5edf592a9c40680c" />

Exporting Data to Excel

ASP.NET Tip: Exporting Data to Excel
A common request of users is to be able to download data for use in Microsoft Excel. This is actually fairly easy to accomplish without a lot of extra work. I do most of my database work with DataTable objects, as I don't need the overhead of a DataSet. I also have a Database wrapper class that is able to easily retrieve data from a SQL Server database. Once I use my function to get my DataTable, I can start exporting the data. For this example, however, I'll use the traditional SqlDataAdapter method to retrieve the data initially.
There are a few tricks to making this work. First, you have to create an ASPX page with no HTML content in it. The only thing that should be in the ASPX page is the Page directive at the top. The second trick is to clear the existing content and send down a new content type. For Excel, you use a content type of application/vnd.ms-excel. This tells your Web browser to expect something that can be handled within Excel. The third trick is to send down the data tab-delimited per column and a newline at the end of each row. After that, Excel does the rest of the work for you.
Here's the code:
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection cn = new SqlConnection("yourconnectionstring");
cn.Open();
SqlDataAdapter da = new SqlDataAdapter("SELECT * FROM Users", cn);
DataTable dt = new DataTable();
da.Fill(dt);
cn.Close();

Response.Clear();
Response.ContentType = "application/vnd.ms-excel";
string sep = "";
foreach (DataColumn dc in dt.Columns)
{
Response.Write(sep + dc.ColumnName);
sep = "\t";
}
Response.Write("\n");
