I have been able to successfully read a row of data from an SQL table using two column parameters. Now I would like to update this row with new information. Is this possible since the reader does not specify which row was read with the 'reader.Read();' command?

I'm just stuck as I can't work out the best way to do it,
Here's a short explanation of my asp.net project.
1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.
In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:
"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".
Some extra info:
- The network folder has read and write permissions for everyone
- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)
- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)
- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)
- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />
Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)
Searching for solutions, I discovered the following:
- if I don't use linked tables, everything works fine (however, I have to use this linked table)
- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.
I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.

View 5 RepliesI want to do is to get the record number in my database of the first record that matches my search. Its to skip to a random point in the database based on user input.
[Code]....
It returns the number of records that preceed the first one to match the string. I have tried to call this procedure from MVC and it always returns -1, so I have a fundamental problem there. I have also tried ot figure out how to just duplicate the code in MVC and I also cannot seem to get anywhere on that front.
Does anyone know a simple elegant solution to either embed this code diretly into MVC or to call my stored procedure from MVC and get the correct integer response back, instead of -1? I am engaged in relearning development after many years, so I am getting stuck on the basics.
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.

I would like also to read a field on first record for print it.
How can i access to my sqldatasource from code behind ?
