How to use ADO and Visual Basic with QODBC

Setup QODBC to work withADO

     Note: QODBC can be accessed from ADO. ADO can be used in Visual Basic (VB), Access, VBScripts, ASP, C++, VB.NET, C# and any other language that supports COM components.

Connection String
     The most difficult part of using QODBC in programming is the connection string. The simplest form includes a reference to a DSN. A system DSN called QuickBooks Data is automatically created when QODBC is installed. QuickBooks Data will be used in all examples but can be substituted with any different DSN name you create.

     Normally ADO pools connections. QODBC does NOT support connection pooling. It is recommended to tell ADO to not do connection pooling on any QODBC connection. This is done with OLE DB Services= -2.

Other options available on the connection string:
bullet DFQ = Path to company file or . (dot) to indicate currently open company file.

bullet OpenMode = F (Follow Company), M (Multi-user), S (Single-user).

bullet DeveloperCode = This is for users of the QODBC v5 OEM version only. It is required to connect to the OEM licensing model. The Code is given to you when you purchase a QODBC v5OEM licensing pack.

bullet ColumnNameLen = This is a number that specifies the maximum length a column name can be. Using this is required in some development environments. Its use will make the returned column names not match the normal defined schema.

Example of simple DSN
sConnectString = "DSN=Quickbooks Data;OLE DB Services=-2;"

Example of a DSNless connection string
sConnectString = "Driver={QODBC Driver for QuickBooks};DFQ=C:Program FilesQODBC Driver for QuickBookssample04.qbw;OpenMode=M;OLE DB Services=-2;"

Example using current ADO syntax
sConnectString = "Provider=MSDASQL.1;Persist Security Info=False;Data Source=QuickBooks Data;OLE DB Services=-2;"

Standard syntax
"DRIVER={QODBC Driver for QuickBooks};SERVER=QODBC;DFQ=.;OLE DB Services=-2;OptimizerOn=No;"

Instructions for Parameters in Standard Syntax

DFQ (./[path to .qbw file]) : . means current company file open in QuickBooks
OLE DB Services = -2
OptimizerOn : Yes/No
OpenMode : F/S/M <=> Follow company setting/Single-User/Multi-user
UseCaseSensitiveRefNumber : Yes/No

[Note: For QuickBooks Online Edition (QBOE) these additional parameters can also be used]
IBizOEConnection : Yes/No
IBizOETicketGUID : (GUID from web login)
IBizOEPromptForLogin : Yes/No

 

Query Data VBS Example

'*****************************************
Const adOpenStatic = 3
Const adLockOptimistic = 3

Dim oConnection
Dim oRecordset
Dim sMsg
Dim sConnectString
Dim sSQL

sConnectString = "DSN=Quickbooks Data;OLE DB Services=-2;"
sSQL = "SELECT Name FROM Employee"
Set oConnection = CreateObject("ADODB.Connection")
Set oRecordset = CreateObject("ADODB.Recordset")

oConnection.Open sConnectString
oRecordset.Open sSQL, oConnection, adOpenStatic, adLockOptimistic
sMsg = "**********************" & Chr(10)
Do While (not oRecordset.EOF)
sMsg = sMsg & oRecordSet.Fields("Name") & Chr(10)
oRecordset.MoveNext
Loop
sMsg = sMsg & "**********************" & Chr(10)
MsgBox sMsg

oRecordset.Close
Set oRecordset = Nothing
oConnection.Close
Set oConnection = Nothing
'*****************************************

 

VBA

Save your VBA file as QODBC Query Data.vbs, To execute the VBS file, Double Click on the file.

VBA


Visual Basic 6 Example

Note: Requires project reference to Microsoft ActiveX Data Objects 2.x Library

'*****************************************
Dim oConnection As ADODB.Connection
Dim oRecordset As ADODB.Recordset
Dim sMsg As String
Dim sConnectString As String
Dim sSQL As String

sConnectString = "DSN=Quickbooks Data;OLE DB Services=-2;"
sSQL = "SELECT Name FROM Employee"
Set oConnection = New ADODB.Connection
Set oRecordset = New ADODB.Recordset

oConnection.Open sConnectString
oRecordset.Open sSQL, oConnection, adOpenStatic, adLockOptimistic
sMsg = "**********************" & Chr(10)
Do While (Not oRecordset.EOF)
sMsg = sMsg & oRecordset.Fields("Name") & Chr(10)
oRecordset.MoveNext
Loop
sMsg = sMsg & "**********************" & Chr(10)
MsgBox sMsg

oRecordset.Close
Set oRecordset = Nothing
oConnection.Close
Set oConnection = Nothing
'*****************************************

Sp_report Query Data VBS Example

Note: For QuickBooks reports, just use sp_report like any other SELECT statement, for example, save the following example as sp_report.vbs to a file.

'*****************************************
Const adOpenStatic = 3
Const adLockOptimistic = 3

Dim oConnection
Dim oRecordset
Dim sMsg
Dim sConnectString
Dim sSQL

sConnectString = "DSN=Quickbooks Data;OLE DB Services=-2;"
sSQL = "sp_report CustomerBalanceSummary show Text, Label, Amount_1 parameters DateMacro = 'ThisMonthToDate', SummarizeColumnsBy = 'TotalOnly'"

Set oConnection = CreateObject("ADODB.Connection")
Set oRecordset = CreateObject("ADODB.Recordset")

oConnection.Open sConnectString
oRecordset.Open sSQL, oConnection, adOpenStatic, adLockOptimistic
sMsg = "**********************" & Chr(10)
Do While (not oRecordset.EOF)
sMsg = sMsg & oRecordSet.Fields("Text")
sMsg = sMsg & " " & oRecordSet.Fields("Label")
sMsg = sMsg & " $" & oRecordSet.Fields("Amount_1") & Chr(10)
oRecordset.MoveNext
Loop
sMsg = sMsg & "**********************" & Chr(10)
MsgBox sMsg

oRecordset.Close
Set oRecordset = Nothing
oConnection.Close
Set oConnection = Nothing
'*****************************************

Is there a way to run a vb script without Reckon Accounts running on the background?

Hi Gary,

You can't fetch QuickBooks data without QuickBooks is running either in background/foreground. QuickBooks needs to be in running mode to access data using QODBC.
