Data Source Name Not Found And No Default Driver Specified (ODBC)?
Jan 3, 2011
I have a ASP.NET webapplication where I use ODBCConnection to connect a MySQL server, it will take the connectionstring from the web.config file and this works grate.
But when I put the same code in a WPF application and hardcode the same connection string I get the followin exception when runnint ODBCConnection.Open() :
Data source name not found and no default driver specified
I have checked the ODBCConnection orbject and its instansiated with the exact same connectionstring as in the webapplication.
The connection string looks like this :
"DRIVER={MySQL ODBC 3.51 Driver};SERVER=X.X.X.X;DATABASE=X;USER=X;PASSWORD=X;OPTION=3"
The X is set to propert values
I am running both from the same computer so the MYSQL ODBC connection is installed correct.

The Error
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
The Story
I've written a page outside of Visual Web Developer 2010 that uses a SqlDataSource object along with a FormView object that works perfect. Building upon those awesome skills I obtained I started to build a project within Visual Web Developer, this time creating an Empty Web Application and went along my happy way building my new site. I used the same techniques and almost the same code as before - just pointing to a different table but I was met with the aforementioned error message.
The Confusing part
Here's the puzzling part - if I take my page I wrote outside of Visual Web Developer, again - it works perfect - no complaints, and add it as a page to the project I've built it now presents the same error message and I have no idea why.
The Tests Completed
I've backed off of targeting .NET 4.0 framework and went to 2.0 as I am not using any specific 4.0 controls or methods at this time. I've taken my page that originally gave me issue and recreated it outside of a Visual Web Developer project and instead as a stand alone page and the exact same code - copy, cut, paste - works perfect!

I get this error message when I connect to the data source on localhostERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specifiedthe connection string is
connectionString="Data Source=DRIVER={MySQL ODBC 3.51 Driver};SERVER=localhost;PORT=3306; DATABASE=database;UID=xxx;PWD=xxx;OPTION=3;pooling=false;"
providerName="System.Data.SqlClient"
it must be some kind of problem in the environment since the connection string works on a remote server. I downloaded the driver and added it with the Data source (ODBC) application in the control panel.

My code is to update a record if it already exists in database else insert as a new record. My code is as follows:
protected void Button3_Click(object sender, EventArgs e)
{
OdbcConnection MyConnection = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=testcase;User=root;Password=root;Option=3;");
MyConnection.Open();
String MyString = "select fil_no,orderdate from temp_save where fil_no=? and orderdate=?";
OdbcCommand MyCmd = new OdbcCommand(MyString, MyConnection);
MyCmd.Parameters.AddWithValue("", HiddenField4.Value);
MyCmd.Parameters.AddWithValue("", TextBox3.Text);
using (OdbcDataReader MyReader4 = MyCmd.ExecuteReader())
{
//**
if (MyReader4.Read())
{
String MyString1 = "UPDATE temp_save SET order=? where fil_no=? AND orderdate=?";
OdbcCommand MyCmd1 = new OdbcCommand(MyString1, MyConnection);
MyCmd1.Parameters.AddWithValue("", Editor1.Content.ToString());
MyCmd1.Parameters.AddWithValue("", HiddenField1.Value);
MyCmd1.Parameters.AddWithValue("", TextBox3.Text);
MyCmd1.ExecuteNonQuery();
}
else
{
// set the SQL string
String strSQL = "INSERT INTO temp_save (fil_no,order,orderdate) " +
"VALUES (?,?,?)";
// Create the Command and set its properties
OdbcCommand objCmd = new OdbcCommand(strSQL, MyConnection);
objCmd.Parameters.AddWithValue("", HiddenField4.Value);
objCmd.Parameters.AddWithValue("", Editor1.Content.ToString());
objCmd.Parameters.AddWithValue("", TextBox3.Text);
// execute the command
objCmd.ExecuteNonQuery();
}
}
}

I'm busy working on an ASP.NET Web Application (3.5) and can't seem to connect to a MySQL DB. I first created the entire application using a WinForms template and everything works 100%, but as soon as I move the exact same code to the Web Application, I can't connect anymore. Here's the code:
Code:
public class DBC {
OdbcConnection connection;
public bool CreateConnection() {
try {
string connFormat = "Driver={MySQL ODBC 5.1 Driver};Server=[SERVER];Database=[DBNAME];User=[UID];Password=[PWD];";
connFormat = connFormat.Replace("[SERVER]", Properties.Settings.Default.DBServer);
[Code] .....
As soon as I try to create the new OdbcConnection instance, I get the error:
Code: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
As noted this works in a WinForms app, and even more strange is that I don't even specify a DSN name...
All I could find from reading through forums all over the internet is suggestions of downgrading the MySQL ODBC driver version, which I'd really rather not...

I'm attempting to load a GridView dynamically on a button is pressed.The gridview has AutoGenerateColumns="True" (set in skin definition) and has a declarative column definitions as follows:
<asp:GridView runat="server"
SkinID="GridViewDetail" ID="gvReport"
DataKeyNames="dateofcompletion">
<Columns>
[code]...
This all works fine the first time, but as soon as I select a different ddlCampaign item, it throws the"A field or property with the name 'FieldName' was not found on the selected data source" ERRORI kinda understand that it has retained the column mappings from the previous datasource assignment/binding and because the new datasource has different column headings it is throwing the error. What I can't seem to achieve is a clear or reset of defined gridview columns before adding the new columns. I cannot clear all columns because part of the GV defn is declarative.e.g.
gvReport.Columns.Clear();
gvReport.AutoGenerateColumns = true;
I have also tried clearing the previously added columns before new assignment/binding but it gives the same error.e.g.
for (int i = 2; i < gvReport.Columns.Count; i++)
{
gvReport.Columns.RemoveAt(i);
}

I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.
