Hi all...
it's a shame I have to ask, but what is the easiest way to do an update on a Access file?

currently I have:
----------------------
string connectionCC = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ Server.MapPath("/data/network.mdb");
string SQLquery = "UPDATE....."
OleDbConnection myConn = new OleDbConnection(lrFuncs.connectionCC);



----------------------
How can I "execute" this query?

string connectionCC = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ Server.MapPath("/data/network.mdb");
string SQLquery = "UPDATE....."
OleDbConnection myConn = new OleDbConnection(lrFuncs.connectionCC);OleDbCommand cmd = New SqlClient.SqlCommand(SQLquery, connectionCC);

connectionCC.Open();
cmd.ExecuteNonQuery(); // this does the update
connectionCC.Close();

You should probably also wrap this in try/catch block too.

Hope this helps,
Alex

Sorry, the I missed the line break, in previous post.
This is how is should look:

OleDbConnection myConn = new OleDbConnection(lrFuncs.connectionCC);
OleDbCommand cmd = New SqlClient.SqlCommand(SQLquery, connectionCC);

Ok, I don't know what's wrong with me... probably to much cut and paste...

Here is the correct one:
string connectionCC = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ Server.MapPath("/data/network.mdb");
string SQLquery = "UPDATE....."
OleDbConnection myConn = new OleDbConnection(lrFuncs.connectionCC);
OleDbCommand cmd = new OleDbCommand(SQLquery, connectionCC);

connectionCC.Open();
cmd.ExecuteNonQuery(); // this does the update
connectionCC.Close();

You should probably also wrap this in try/catch block too.

the line:
---------
OleDbCommand cmd = New SqlClient.SqlCommand(SQLquery, connectionCC);
---------
does not work, SqlClient gets red marks and the debugger says: ";" expected.
Any idea?

Hehe, we posted at the same time ;)
Anyways, still some probs with your code:

OleDbCommand cmd = new OleDbCommand(SQLquery, connectionCC);
needs to be
OleDbCommand cmd = new OleDbCommand(SQLquery, myConn);

but now it works, so thank you ;)
