DBGrid, Oracle, RDO, and Inserting Records

Hi. Need to know how to use the DBGrid to access data in an Oracle database.
My business need is to allow users the ability to review data that has been uploaded into the database into several tables. Once they fix any data related problems, I need to call a stored procedure to process the data and write out a delimited file that another program will read.

I need this by next week and dont have the time to learn everything I need to know about VB5 between now and then. Figured I would use the DBGrid control that comes with VB5 Enterprise Edition but it seems flakey. I used the Forms Wizard to attach to the database and pick the columns I need from a table. When I run the program, no data appears. Havent been able to figure out how to set programatically.
When I accidently!! got it to sortof work once, it blew chunks when I tried to insert a record.

Any code samples would be VERY appreciative.
Have figured out how to use RDO to get a result set but not how to get the grid to use it or how to use it to update/insert data.

I dont know how hard this question really is. My guess was that someone that knew VB pretty good would be able to do this in a weekend but the 3 VB programmers we have here say they dont know anything about RDO and are terrified of oracle.

Thanks,

Hi Davidson,
Just try this simple one.
First goto Project---> components---> and choose both
Microsoft DBGrid Control and
Microsoft Remote Data Control
and choose apply and OK.

Now in the form, open a new form and insert both the above two controls and change the properties as below.

DBGrid1 Control:
AllowAddNew = true
AllowUpdate = true
DataSource = MSRDC1

MSRDC1 Control:
Connect = "DSN=temp;UID=sa;PWD=;DATABASE='MIS';"
 'mis is the database name
CursorDriver=rdUseOdbc
Datasourcename=temp 'temp is the dsn name
ReadOnly=False
Resultsettype=rdOpenKeyset
sql="Select * from emp" ' emp is the table name
visible = false

Save it and run this simple one.
