Sorry, no experience with the SQLitePlus-COM-wrapper
(maybe you should ask their technical support).
In case you want to try out something, working
similar to "ADO/DAO-style"...
The following example is Code for my COM-wrapper,
which is available here:
www.datenhaus.de/Downloads/dhRichClientDemo.zip
It consists of three Binaries, placed in the
Public Domain:
dhRichClient.dll (COM-Dll - ADO-like WrapperClasses)
sqlite35_engine.dll (StdCall-Dll, based on SQLite 3.5.7)
DirectCOM.dll (Std-Dll, allows regfree COM-instancing)
Small example how to use it, including the
creation of a new DB, in case the file doesn't
exists yet:
Dim Cnn As cConnection, Cmd As cCommand, Rs As cRecordset
Dim i As Long, FileName As String
FileName = "c:\MyFile.db"
Set Cnn = New cConnection 'create a Cnn-Object
On Error Resume Next
Cnn.OpenDB FileName 'attempt, to open a DB-file
If Err Then 'DB-File doesn't exists...
Cnn.CreateNewDB FileName '...so we create one
End If
'Ok, let's create a table
Cnn.Execute "Create Table If Not Exists " & _
"Tbl(ID Integer Primary Key, Txt Text)"
'now we insert a few records over a Command-Object
Set Cmd = Cnn.CreateCommand("Insert Into Tbl Values(?,?)")
For i = 1 To 5
Cmd.SetText 2, "SomeText_" & i
Cmd.Execute
Next i
'and finally we request a Resultset...
Set Rs = Cnn.OpenRecordset("Select * From Tbl")
Do Until Rs.EOF 'loop over it...
Debug.Print Rs!ID, Rs!Txt '...and print its contents
Rs.MoveNext
Loop
