try the code below...this is just a snippet....you have to properly declare the variables or path of the file and you have to check for proper file name and extension also where needed....
Dim conStr As String = "provider=Microsoft.Jet.OLEDB.4.0;data source=" + filepath + "; Extended Properties=Excel 8.0;"<br />
''"filepath" is the path of the .xls file <br />
Dim sql As String = "select * from [Sheet1$]" ''"Sheet1" is the name of the excel sheet<br />
MyConnection = New System.Data.OleDb.OleDbConnection(conStr)<br />
MyConnection.Open()<br />
MyAdapter = New System.Data.OleDb.OleDbDataAdapter(sql, MyConnection)<br />
dim myDs As DataSet = New System.Data.DataSet<br />
MyAdapter.Fill(myDs)
let me know if you face any problem

Here is a C# code
//-------------------------------------------
private DataSet PerformQueryIntoDataSet(string strFileName,string sheetName)
{
string strConn;
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFileName + ";" + "Extended Properties=" + Convert.ToChar(34).ToString() + "Excel 8.0;HDR=YES; IMEX=1;" + Convert.ToChar(34).ToString();
//You must use the $ after the object you reference in the spreadsheet
OleDbDataAdapter myCommand = new OleDbDataAdapter("SELECT * FROM ["+ sheetName + "$]", strConn);
DataSet myData = new DataSet();
myCommand.Fill(myData, sheetName);
return myData;
}
//-------------------------------------------

It is a common mistake.
Make sure IIS is not set to allow anonymous users. This will force a principle to be created with security information.

Capture the keydown event of the list/combo box in javascript and find the string what you pressed. You have to concatinate the keys you pressed and flush it after some interval of time.

I wan`t to give various options 2 operate on the data and to do this i want 2 provide a dropdown at the end of each row containing various options such as change,remove etc and on selection change the corresponding row of the datagrid must be updated.How do i generate the dropdown for each row and associate it with that row???

Use a template column like this:
<asp:DataGrid ....>
<Columns>
// put your other columns here ....
<asp:TemplateColumn HeaderText="Action">
<asp:DropDownList ID="ddAction" runat="server">
<asp:ListItem Text="(select an option)" />
<asp:ListItem Text="change" />
<asp:ListItem Text="remove" />
</asp:DropDownList>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>
|
|

|

How do i fire it`s selection change event and the change must be reflected in the corresponding row.i.e how do i know which dropdown was selected and which row to modify???
Thanks in advance!!!

Set the AutoPostback peoperty of the DropdownList and then capture the SelectedIndexChanged Event of the DataGrid.

Do you want to upload file from client to server or download from server to client. ? If you want to copy file from server to client, ASP.NET should have write access in the client machine where u want to copy the file

wrote: upload a file to the client machine
The above phrase means download, not upload...
