Just after installing MS Visual Basic 6the following line generated by the VBApplication Wizard gives a "User defined type not defined" compile error.

>>>Private Sub datPrimaryRS_MoveComplete(ByVal adReason As ADODB.EventReasonEnum, ByVal pError As ADODB.Error, adStatus As ADODB.EventStatusEnum, ByVal pRecordset As ADODB.Recordset)<<<<

So I must need to manually set a reference to some library to use ADODB.

Could somone help.

Hi neilhoman,

Try to add M$ ActiveX Data Object 2.1 (or 2.5) Library from Reference to see if problem remains.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I had a problem like yours. When I use the app wizard.

Add a reference  ActiveX Data Object 2.1 (or 2.5)  and other to Microsoft ActiveX Data Objects Recordset 1.5 library.

Just try setting  a variable to reference a recordset.
eg
Dim Rs As ADODB.Recordset

After 'ADODB.' if it doesnt bring up a recordset in the list of objects then you know the reference to the
ActiveX Data Object 2.1 library is at fault.

Alternativly dont use the wizard and manual code heres one of my simple examples.

Dim Rs As ADODB.Recordset
Dim Cn As ADODB.Connection

Set Cn = New ADODB.Connection
Set Rs = New ADODB.Recordset
     
Cn.Open "Provider=SQLOLEDB;Data Source=" & g_strServer & ";Initial Catalog=" & g_strDB & ";User Id=" & g_Uid & ";Password=" & g_UPwd & "; "
'Return all active sites
Rs.Open "Select * From tblSites where active = 1", Cn

...Do Stuff with the returned data....

Set Rs = nothing
Set CN  nothing


Obviously your connection string will be different so

cn.open "YOUR CONNECTION PROPERTIES HERE"

Good luck.

Change it to this:

Private Sub datPrimaryRS_MoveComplete(ByVal adReason As ADODB.EventReasonEnum, ByVal pError As ADODB.Error,
adStatus As ADODB.EventStatusEnum, ByVal pRecordset As ADODB.Recordset20)

Manually in your code, also you will need to change any similar event raised by this control. The reason is that you have the older version of the control that is only compatible with ADO 2.0, as you have ADO 2.1 or higher installed (probably 2.6 by now if you have followed other advice here) there was a change in the recordset object's interface from 2.0 to 2.1. Whilst this is something that should never have happened without changing the name of the object it did and we have to work around it. The only other workaround is to install VB SP4 or higher so that the newer version of this control is available that handles this automatically.

The change in the interface for this object is not something that will affect operation in any way that you will notice so don't worry about it.
