We are evaluating using PB 2017 R2 to convert a number of PB 11.5 COM components to .NET assemblies. All of these instantiate datawindows using PFC / PFE extensions.

I migrated one component to .NET, then attempted to load it from another .NET assembly. The load failed with this stack trace:

Sybase.DataWindow.DataWindowServerLoadFailedException: DataWindow Server PBDWM150.DLL or required DLLs (atl71.dll, msvcp71.dll or msvcr71.dll)  not found.
   at Sybase.DataWindow.DataStore.InitDataStore()
   at Sybase.DataWindow.DataStore..ctor()
   at Sybase.PowerBuilder.WinWebDataWindowCommon.DataStoreWrapper..ctor(PBDataStore ds)
   at Sybase.PowerBuilder.WinWebDataWindowCommon.PBDataStore..ctor()
   at c__pfc_n_ds..ctor()
   at c__n_ds..ctor()

All PB 2017 Runtime Packager files, including Sybase dlls, have been installed. In addition, I added the following (as stated in Help):

atl71.dll
ATL80.dll
atl100.dll
gdiplus.dll
msvcp71.dll
msvcp80.dll
msvcp100.dll
msvcr71.dll
msvcr80.dll
msvcr100.dll

Any suggestions for troubleshooting? My next step is to begin narrowing down possibilities by removing functionality from n_ds and pfc_n_ds.

Thanks,

Don Olliver

Hi,

unfortunately I have no answer, I just have the same problem.

Have you found a solution?

Hi Markus,



Although my code did not reference it, the solution was to install PBDWM170.dll. I believe it includes a modified version of datawindow.net, which is probably required for datawindow access in a PB 2017 .NET assembly.

You need to include the PFC and PFE libraries in with your .NET assembly.

The DeployLog.txt file shows that both libraries are included.

Hi, 

I see this:

You have a reference to PBDWM150.DLL  in someplace, you must have a reference to PBDWM170.DLL (or equivalent in your version PB 2017)  and you have PBDWM150.DLL

Sybase.DataWindow.DataWindowServerLoadFailedException: DataWindow Server PBDWM150.DLL or required DLLs (atl71.dll, msvcp71.dll or msvcr71.dll)  not found.

 

I hope that the observation will serve you

Regards !

Thank you, but our code is not referencing that DLL. I believe this exception is thrown by one of the other PB 2017 runtime DLLs.
