DLL(from C++) in VFP

[mensud]

Hi,
I am trying to call some functions from dll developed in VC++, but I can not even create object in VFP for this DLL.
I already tried with DECLARE..., and CREATEOBJECT, but does not work.
Any suggestion?

Thanks

What kind of DLL is it? There are many kinds of DLLs and some simply can't be called from VFP. Do you have any sample code that "calls" this DLL from any language? (e.g. VC++, VB, Access, etc.)

Yes, I have samples in VB.
The next piece of code creates the session manager object and is used to open a connection and begin a session with QuickBooks

Dim SessionManager As New QBFC2Lib.QBSessionManager
SessionManager.OpenConnection cAppID, cAppName
SessionManager.BeginSession "", omDontCare

DLL is named: qbfc2_1.dll

While I don't have this DLL to try, I'd guess:

SessionManager = CreateObject("QBFC2Lib.QBSessionManager")
SessionManager.OpenConnection(cAppID, cAppName)
SessionManager.BeginSession("", omDontCare)

This assumes that "QBFC2Lib.QBSessionManager" is in the registry that way, and that you have appropriate variables declared and intialized for cAppID, cAppName and omDontCare.
