Please post your code or run your application with the Break point and try to locate in which line the error shows.
We are not magic man without seeing the code how can we tell where the error is.

Here is a code:
try
{
string cmdstr="SELECT * FROM tablename where dp_head='"+ dpdhead.SelectedValue +"'";
con=new OleDbConnection(cons);
cmd=new OleDbCommand(cmdstr,con);
con.Open();
OleDbDataReader dr = cmd.ExecuteReader();
bool chkrec = dr.Read();
if(chkrec == true)
{
string dasv = dr.GetInt32(0).ToString();
txtacno.Text = dasv;
}
//
Output
'/LM/w3svc/1/root/expdemo-5-128280938191702288': Loaded 'c:\windows\microsoft.net\framework\v1.1.4322\temporary asp.net files\expdemo\280c9982\bd477ac7\gottf48d.dll', Symbols loaded.
// Now

You may be better off by using a Parameter List for your OleDBCommand Object.
replace your appropriate lines:
string cmdstr = "SELECT * FROM Tablename where field = @fieldvalue;";
cmd = new OleDBCommand(cmdstr,con);
cmd.Parameters.AddWithParameter("@fieldvalue",dpdhead.SelectedValue);
Parameter Lists help organization And is another obstacle for Hackers.
Also look to this:
string dasv = dr[0].ToString();

Respected Gurus
I m using following code to import data from an excel file..
It works fine except one problem that
whenever i m trying to delete the file which i have saved on the server by using
file.delete(strfilename)
i left with the error "you do not have permission"
I think i have not closed the excel file.
how can i close it programmatically so that i can delete it also.
Dim strfilename As String
' Check the first open file dialog for a value
If Not (Me.File1.PostedFile Is Nothing) Then
' Get a reference to PostedFile object
Dim attFile As HttpPostedFile = File1.PostedFile
' Get size of the file
Dim attachFileLength As Integer = attFile.ContentLength
'Make sure the size of the file is > 0
If attachFileLength > 0 Then
' Get the file name
strfilename = Path.GetFileName(File1.PostedFile.FileName)
'Preceed the file name with "attachments/" so
'the file is saved to our Project's attachments Folder
strfilename = "Uploads/" + strfilename
'Save the file on the server
File1.PostedFile.SaveAs(Server.MapPath(strfilename))
End If
End If
Dim strConnectionString As String = String.Empty
'----------------------------------------------------------
'strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Driver=Microsoft Text Driver (*.txt;*.csv);Data Source=" + Server.MapPath(strfilename) + ";Extensions=asc,csv,tab,txt;Persist Security Info=False"
'----------------------------------------------------------
strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath(strfilename) + ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"""
Dim cnCSV As New OleDbConnection(strConnectionString)
cnCSV.Open()
Dim cmdSelect As New OleDbCommand("SELECT * FROM [sheet1$]", cnCSV)
cmdSelect.CommandType = CommandType.Text
Dim daCSV As New OleDbDataAdapter
daCSV.SelectCommand = cmdSelect
Dim ds As New DataSet
daCSV.Fill(ds)
after using the dataset.
at last i am trying to delete the file.
which give me the error.
Please Help.

please check out your system configuration. have your system has permission to delete any file. could be possible this.

Your web site runs under an app pool. That app pool has an identity. That user that the app pool is running as needs to be able to delete files in the correct directory. Often it makes sense to create a new app pool for each new web application. Then you can create a network user for that specific application and give that user the correct rights.

This doesn't work, you're using ASP.NET, not asp.
If you're using ASP, you're not using ASP.NET, and you're in the wrong forum. This sure is bringing back bad memories of asp, what makes you think you're using ASP.NET 2.0 ?

hi
i want generate gridview programmatically to but having a error in
hyp1.DataNavigateUrlFields = "link";
ERROR:- cannot implicitly convert type 'string' to 'string[]'
plzzzz help me
thanks in advance
DataTable dt = new DataTable("dtable");
DataRow dr1;
DataRow dr2;
dt.Columns.Add(new DataColumn("Text", typeof(string)));
dt.Columns.Add(new DataColumn("link", typeof(string)));
dr1 = dt.NewRow();
dr1[0] = "Yahoo";
dr1[1] = "http://www.yahoo.com";
dt.Rows.Add(dr1);
dr2 = dt.NewRow();
dr2[0] = "Google";
dr2[1] = "http://www.google.com";
dt.Rows.Add(dr2);
GridView GV = new GridView();
GV.AutoGenerateColumns = false;
HyperLinkField hyp1 = new HyperLinkField();
hyp1.HeaderText = "UsefulLinks";
hyp1.DataTextField = "Text";
hyp1.DataNavigateUrlFields = "link";
hyp1.Target = "_blank";
GV.Columns.Add(hyp1);
GV.DataSource = dt;
GV.DataBind();
plhPlaceHolder.Controls.Add(GV);
|
|

|

It is expecting a string array. So you need some code like this:
string[] tmp = new string[1] {"link"};
hyp1.DataNavigateUrlFields = tmp;
Hope that helps.

i m using datatable field to bind link to that field
how to convert that field in a string array
|
|
|
|

Isn't the field just called "link"? I am not sure what your issue is? You tried the code I posted and it didn't work? What error did you get?
