Hello All,

on windows server running a EXE the exportJson retunrs and empty string

all the other features are working

do we need any aditional DLL other than the ones of the runtime packager and the C++ runtime?

Using process monitor we found that for some reason the pbjson170 was damage

we reinstall the runtime and it works

Hi

did you check the DLLs deployed: pbjson.dll which has dependencies into MSVCP100.DLL and MSVCR100.DLL.

If so my other idea is whether the datawindow object is referenced dynamically and you deploy an exe and not a pbd containing the datawindow object. If so the datawindow is missing and not the Json generation would be the problem.

Regards
Arthur

Hello Chris
yes we have copy the microsft DLL's to the client machine where the exe is running

everything else is working only the exportJson returns an empty string (the DW have the data and not null values)

the same DW with the same data is working where PB is installed

Hi Andres;

   Yes, there are some non-PB DLL's and Microsoft ones that you need as well. If you open the PB Help file from the IDE and then search for the keywords "runtime files", you can then follow the "List of runtime files" link. In there you will get a detailed list of all DLL's required for any PB App EXE's runtime support. Note that some DLL's that are required are not included in the PB Packager utility either and must be manually copied (an issue corrected in the new PB2019 R3 PowerClient feature).

HTH

Regards ... Chris
