Other applications (including macros written in Microsoft Excel or Access) can have full read/write access to VT Transaction+ data files using the VT Accounting Objects (VTA.dll) software component.
Other applications can also invoke most of the dialogs used by VT Transaction+ using the VT Accounting Dialogs (VTADlgs.ocx) software component.
Full details for both components are contained in the help file C:\Windows\SysWOW64\VTComponents.chm (or C:\Windows\System32\VTComponents.chm on 32-bit PC's). The components and the help file are installed as a standard part of the VT Transaction+ installation. The components are intended for use by programmers.
A Microsoft Excel workbook containing sample macros can be downloaded from www.vtsoftware.co.uk/tranplus/samplecode.xls. Please note this will work in the 32-bit version of Excel but not the 64-bit version of Excel. If you have the 64-bit version, you can easily reinstall it as the 32-bit version as described here.
Even if you have no programming knowledge, you can still run the sample macros in this workbook to get an idea of what is possible.
VT Accounting Objects has a wide range of uses. For instance, you could use it to write a program to automatically generate, save and print the sales invoices for your business. The sample macros workbook includes a macro for generating and printing an invoice.
If you are a programmer, the Concepts topic may help you understand the object model underlying VT Accounting Objects.
