That's the effect of the ASP.NET page lifecycle. Use a static class to hold the connection. That way, it'll persist across page reloads.

Use <authentication mode="Windows" /> in your web.config. This is generally used for Intranet applications .
U can retrieve the current logged-in user name as follows.
System.Web.HttpContext.Current.User.Identity.Name

You wont be able to extract the password. It's maintained by Windows and is hashed!!
Just imagine what would happen to security if you could find out a windows password using a few lines of code!!

try
{
string strConnection =("Driver={Microsoft Excel Driver (*.xls)};DriverId=790;bq=C:\\Salary.xls;DefaultDir=c:\\;");
OdbcConnection conn = new OdbcConnection(strConnection);
//conn.Open();
OdbcCommand command = new OdbcCommand("SELECT * FROM [Sheet1$]",conn);
// command.Connection = conn;
// command.CommandType = CommandType.Text;
// command.CommandText = "SELECT * FROM [Sheet1]";
OdbcDataAdapter da = new OdbcDataAdapter(command);
DataTable dt= new DataTable();
conn.Open();
da.Fill(dt);
conn.Close();
//return dt;
}
catch (Exception ex)
{
lblError.Text = ex.Message;
//return null;
}
}
I get an error like this.
ERROR [42S02] [Microsoft][ODBC Excel Driver] The Microsoft Jet database engine could not find the object 'Sheet1$'. Make sure the object exists and that you spell its name and the path name correctly.

OleDbCommand command = new OleDbCommand("SELECT * FROM [Sheet1$]", conn);<br />
OleDbDataAdapter da = new OleDbDataAdapter(command);<br />
DataTable dt = new DataTable();<br />

For server controls we have property "cssClass" use it. For example
Label1.cssClass="className"
Lets work it Out.........!

hi all...
i was waiting 4 reply from anyone till now but now i got it from somewhere & npw i m uploading it here so it can be beneficial to all of u if u have to work like this...
the solution is very simple, I am assuming you have a .TTF Font file in some location. Use In the following code I am loading my font file badrobot.ttf from C: drive and using it to change the font of a Label in my application.
System.Drawing.Text.PrivateFontCollection fontcoll = new System.Drawing.Text.PrivateFontCollection();
fontcoll.AddFontFile(@"C:\badrobot\badrobot.ttf");
System.Drawing.Font font = new System.Drawing.Font("bad robot", 20);
this.label1.Font = font;
fontcoll.Dispose();
In WinAPI, the same can be achieved using AddFontResourceEx() and RemoveFontResourceEx().

 Hi, Our project which has been developed on .net2002 is working fine. Now I have introduced some drop down list in search modules of the projects. They also working fine in the local system but in the server, ddlist are not getting filled with the data present in database. And also i want to introduce some more pages to it. They are all working fine in local system. but when i copy them to server where the original project has been deployed, it is giving the following error. Now the project is been enhancing using, .NET 2005
Server Error in '/dbs' Application.

Well I think you haven't uploaded 'Dash_Board.dll' in Bin Directory at Web Server...! Please check this issue first
Lets work it Out.........!

I have uploaded. but no luck. I cant find any reasons for this problem.

I think you need to be a bit more specific.
1. If your dropdownlist is not getting populated, check whether the database has any data (your dev database may have data, but your test/production db may not)
2.
Now the project is been enhancing using, .NET 2005
Are you saying that you've included pages developed in .NET 2.0 with the older ASP.NET application?

From the Error Message you have posted, I found that, your Application is not deployed in a WebSite where .NET 2.0 framework is installed.
Check the whether .NET framework version installed and running in that server. You need to have .NET 2.0 framework installed and assigned to the WebSite.

But the project has been already deployed.

Data is here in the database. You are right, i have included the pages developed in .NET 2.0 with the older ASP.NET application
