RDO/RDC AND COMBO BOXES

How do I get a list for the combo box when using rdo/rdc. When the form is loaded so that when the user uses the combo box they have their list of selections to use from a reference table?

MaryD,

  Sorry, don't really know what you want. Are you going to use RDO to fetch data from remote database and then list out the fetched data to combo box?

Yes thats what I would like to do. The tables are on the server and I need to retrieve that information and load a combo box. I will also have multiple tables to pull from in some cases.

Thanks

With RDC:
MSRDC#:Code your CONNECT string and SQL on the RDC.
DBCOMBO#: Set the ROWSOURCE = MSRDC# and the LISTFIELD = FieldName.  This is the minimum to get a list. To tie the selection to anything use DATASOURCE, DATAFIELD & BOUNDCOLUMN.
BOUNDCOLUMN allows you to retrieve the bound column value via the BOUNDTEXT property in code. DATASOURCE and DATAFIELD will bind your result or initialization to another control.
With RDO:
Basically the same thing only you have to code the whole thing and read the resultset palcing your items in a combo box with the ADDITEM method. For Example (SQL SERVER):

Dim Env As rdoEnvironment
Dim Cn As rdoConnection
Dim rs As rdoResultset
Dim i As Integer

Set Env = rdoEnvironments(0)
Set Cn = Env.OpenConnection("", rdDriverNoPrompt, True, "UID=;PASSWORD=;DSN=YOURDSN;DATABASE=YOURDB")
Set rs = Cn.OpenResultset("Select * from YOURTABLE")
' yes the first record is already available w/out a movefirst...
i = 0
Do While Not rs.EOF
  Combo1.AddItem rs.rdoColumns(0), i
  i = i + 1
  rs.MoveNext
Loop
