Missing dll in my installation?

Carlos123456

Hello, it looks like my install is missing DBInterface.dll and .lib. I'm using the WinProp API for a large project but I cannot build it due to a linker issuse with those files. I cannot find them anywhere in my installation. Any help is greatly appreciated

Hello Carlos,

In WinProp there is no DBInterface.dll, also the example name “sim_code” does not point to an example provided with WinProp.

Maybe this is a library used additionally by you? If not, you could provide us the example and we'll have a look.

Best Regards,

Hello Carlos,

Please see the answer below.

"The DBInterface.dll was incorrectly documented within the v2025.1 user guide. This is already fixed in current versions (V2026).

The correct library is “InterMan.dll”. The “outdoor_propagation_openmp” can be used as an example for how to use the “InterfaceBuildings...” functions. And how to link the InterMan library."

Best regards,

Jaehoon

Hello @Carlos123456,

Could you share the error message (or screen shot) showing the missing DLL file and lib file?

Which version are you using?

Best regards,

Jaehoon

Hello Jaehoon,

I apologize for the wait. I'm using version 2025.1

This the error code message I got: "cannot open file 'C:\Program Files\Altair\2025.1\feko\api\winprop\examples\sim_code....\export\winprop\64\DBInterface.lib' "

I set the same path for the DBInterface.dll file. But they are not there so I was looking through my installation folder to see where they are, but I did not find them.
I'm using the student edition of the software, if that is relevant.

Best regards,

Carlos

Hello Jaehoon,

I am using InterfaceBuildingsInit function.

This appears in pg. 83 of WinProp API reference guide.

sim_code is a modified version of the outdoor_propagation example I put into a separate folder
