Create .odc file

MeleKoneya — Thu, 13 May 2010 15:38:50 GMT

I would like to create an .odc file to connect to SQL Server 2005 within a C# project.    I am using the SQL connection to create an XYTheme from a table and would like the .odc connection to be created and discarded after use each time the program runs.

Here is the code that I have so far.    Each time I debug it,   the 'Add OLD DB Connection' form is launched.     I think the problem may be with the Properties that I am using.    I have not found any examples of how to do this, so any help would be appreciated.

Thanks,

Mele

private static string CreateODBCconnectionFile(string server, string user, string password)
        {
            IPropertySet propSet = new PropertySetClass();

            propSet.SetProperty("Provider", "SQL Native Client");
            propSet.SetProperty("Data Source", server);
            propSet.SetProperty("User name", user);
            propSet.SetProperty("Password", password);
            IWorkspaceFactory2 pWSFact = (IWorkspaceFactory2)new OLEDBWorkspaceFactory();


            return pWSFact.Create("d:\\temp\\", "test.odbc", propSet, 0).ToString();
        }

I never can remember the properties ... nor where to find them in the documentation.
So sometimes what I do is set up a connection in ArcCatalog, select it in the treeview, then run vba code that lists the properties, then write .NET code that sets those properties. It's doing things like this that makes me worry about life without VBA.

Option Explicit
Sub ListConnProps()
    Dim pGxApp As IGxApplication
    Set pGxApp = Application
    If Not TypeOf pGxApp.SelectedObject Is IGxDatabase Then
        Debug.Print "select a geodb first"
        Exit Sub
    End If
    Dim pGXdb As IGxDatabase2
    Set pGXdb = pGxApp.SelectedObject
    Dim names As Variant, values As Variant
    Debug.Print pGXdb.WorkspaceName.WorkspaceFactoryProgID
    pGXdb.WorkspaceName.ConnectionProperties.GetAllProperties names, values
    Dim l As Long
    For l = 0 To UBound(names)
        Debug.Print names(l), values(l)
    Next l
    
End Sub

Thanks! This gave me exactly what I was looking for. I too wonder what ArcLife will be without VBA

After stepping away from this code for a while to do other things.    I am back to it and not having much success.

I was able to extract the connection properties from my existing ODBC connection, but each time I try to create a connection file through ArcObjects I am giving the Data Link Properties Form from ArcGIS Desktop.

private static IWorkspaceName CreateODBCconnectionFile()
        {
            IPropertySet propSet = new PropertySetClass();
            propSet.SetProperty("Provider", "SQLNCLI");
            propSet.SetProperty("Password", "pwd");
            propSet.SetProperty("Persist Security Info", "True");
            propSet.SetProperty("User ID", "UID");
            propSet.SetProperty("Initial Catalog", "ComDevPrmt");
            propSet.SetProperty("Data Source", "server");

            IWorkspaceFactory2 pWSFact = (IWorkspaceFactory2)new OLEDBWorkspaceFactoryClass();
                        propSet.GetAllProperties(out names, out values);



            return (IWorkspaceName)pWSFact.Create(@"d:\workspace\", "tmpfile.odc", propSet,0);



        }

I have been able to create an .sde file using similar code as shown below.

public static IWorkspaceName CreateConnectionFile(string server, string instance, string user, string password, string database, string version, string SDEdir, string SDEfile)
        {

            string SDEFullName = SDEdir + SDEfile;
            if (File.Exists(SDEFullName))
            {
                File.Delete(SDEFullName);
            }
            IPropertySet propertySet = new PropertySetClass();
            propertySet.SetProperty("SERVER", server);
            propertySet.SetProperty("INSTANCE", instance);
            propertySet.SetProperty("DATABASE", database);
            propertySet.SetProperty("USER", user);
            propertySet.SetProperty("PASSWORD", password);
            propertySet.SetProperty("VERSION", version);
            IWorkspaceFactory2 workspaceFactory = (IWorkspaceFactory2)new
            SdeWorkspaceFactoryClass();
            return workspaceFactory.Create(SDEdir, SDEfile, propertySet, 0);
        }

Any help is appreciated.

Thanks,
