Differences between 32-bit and 64-bit VTS

In general there is very little difference between 32-bit and 64-bit VTS from a VTS programmer’s perspective. The one major difference is that, in 64-bit VTS you can go well beyond the 2 GB memory limit for your VTS applications. The disadvantage is that 64-bit VTS uses significantly more memory than 32-bit VTS to run the same application.

 

The following functions have differences in behavior between 32-bit and 64-bit VTS:

•      ODBCConnect / TODBCConnect

•      ODBCConfigureData

•      ODBCSources

•      DLL / LoadDLL

•      ComClient

•      MakeFixedBuff

 

You can use the Version function to determine if you are running 32-bit or 64-bit VTS.
