Hi Sonia,

You better try this code using vb.net

Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=RegisteredUsers.xls")
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
Me.EnableViewState = False
Dim oStringWriter As System.IO.StringWriter = New System.IO.StringWriter()
Dim oHtmlTextWriter As System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter(oStringWriter)
oHtmlTextWriter.WriteLine("Registered Users: ")
'Me.ClearControls(dgGrid)
DataGrid1.RenderControl(oHtmlTextWriter)
Response.Write(oStringWriter.ToString())
Response.End()

Does your hosting company host ASP.NET applications. The .NET Framework is required on your hosting server for the controls to be rendered. Your ASP.NET Application will not work on a server that does not have .NET Framework. Hope that helps.

SqlDataSource Refresh Problem

Dear sirs:

I have a Web Form with an SqlDataSource with a simple select statement, and a GridView control that is tied to it. There is a ComboBox and a Submit button as well. When a selection is made (the first time) in the combo box and then the submit button is clicked, the Selecting Event for the SqlDataSource fires.

However, on subsequent "submits" I cannot get the event to fire again. What do I need to do to get this event to fire; thus letting me know that new data is being fetched from the database?

Thank you,

R. Hyland

Here is the code for the SqlDataSource:

from requesthistory rh

inner join movehistory mh on rh.itd_number = mh.itd_number
inner join movedescription mds on rh.movedescr_id = mds.movedescr_id

where rh.movedescr_id = 1 AND mh.discrepancy_id = 25 AND EXTRACT(MONTH FROM mh.historydatetime) = :MONTH_ID

group by to_date( mh.historydatetime , 'DD-MM-YYYY' ) ,
rh.movedescription ,

order by to_date( mh.historydatetime , 'DD-MM-YYYY' )" onselecting="sqlDataSourceG5WingRailCar_Selecting">
<<selectparameters>>

<<asp:controlparameter
="" controlid="dropDownListMonth" name="MONTH_ID" propertyname="SelectedValue">>

There really is no code for the Selecting Event, other than just capturing some text into a label when the event occurs (for testing purposes).

Classic ASP to C# ASP.net

Hi

I am currently working on converting a classic asp page to c# asp.net . I have come across this and was wondering if anyone would know the c# equivalent. It basically runs through a url string and takes the values out after every '=' sign. I was wondering if anyone could help.

function findField( fieldName, postResponse )
items = split( postResponse, chr( 13 ) )
for idx = LBound( items ) to UBound( items )
item = replace( items( idx ), chr( 10 ), "" )
if InStr( item, fieldName & "=" ) = 1 then
' found
findField = right( item, len( item ) - len( fieldName ) - 1 )
Exit For
end if
next
end function

Thanks
Dean

You would just use the Split('=') command on your string. For instance:

string[] replies = reply.Split('=');

Ouch. First let's clean up that VBScript code:

Function FindField(ByVal fieldName, postResponse)
   fieldName = fieldName & "="
   items = Split(postResponse, vbCrLf)
   For idx = 0 to UBound(items)
      If InStr(item, fieldName) = 1 Then
         FindField = Mid(item, Len(fieldName) + 1)
         Exit For
      End If
   Next
End Function

Now it's easy to translate:

public string FindField(string fieldName, string postResponse) {
   fieldName += "=";
   foreach (string item in Regex.Split(postResponse, "\r\n")) {
      if (item.StartsWith(fieldName)) {
         return item.SubString(fieldName.Length);
      }
   }
}
