environment handles

[cBarry263]

Could someone please explain to me what "environment handles" and "connection handles" are? I have never heard these terms yet they are showing up everywhere I this code I am working on.

It is a DB connection handle. The application connects to an SQL database, there are tons of API's included, for example one of them is SQLAllocEnv. They all seem to take handles as arguments or return handles and I have no idea what it means by a handle.

Are they using Libs?

 

[cBarry263]

Yes, if by

 

[cBarry263]

Oops. Yes if by libs you mean something like
Private Declare Function SQLAllocEnv Lib "db2cli.dll" (ByRef phenv As Integer) As Short

 

[sevenhalo]

If I had to take a stab at it, The class/module/namespace used to hook the libs is probably the handle.

Module adc1132
Declare Function adc11_get_driver_version Lib "ADC1132.dll" () As Integer
End Module
