VBEvents is located in <Installation Location>\Program Files (x86)\Attachmate\VerastreamSDK\samples\VB.
A VB.NET version of this sample is located in <Installation Location>\Program Files (x86)\Attachmate\VerastreamSDK\samples\.NET\VB.
If you did not install the VSDK COM/.NET Support option, these sample applications are unavailable.

Attachmate Verastream SDK for Unisys and Airlines objects require Visual Basic v. 6.0 or later. COM and .NET applications developed with the Verastream SDK do not support the 64-bit JRE . For these applications, use the 32-bit JRE. Running a COM or .NET application using the 64-bit JRE causes COM automation error 80131534, as displayed in the following message: |
