UDF compatibility V 8.1 to V 10

[Nick]

I have a number of reports that contain the Pageno() function wrapped in a udf. These reports are distributed with a vertical application that is currently using the V8.1 runtimes with no problem.____I am attempting to distribute the V 10+ runtime to take advantage of the HTML export, however none of the reports execute and I get a message that I must edit the calculated field in the UDF.____Is there some type of conversion that can be done, or do all 100 reports need to be edited in order to be compatibile with V10.?

Try opening one of these reports in the V10 designer and see if it behaves and if the UDF shows in the UDF list.__If yes, then make sure that the UDF file is in indeed in the runtime directory.__If no, add that UDF.____Kathleen__R&R Support

When I open the report in the 10+ Report Designer I get the exact same problem. The message tells me I must edit the field.____When I go to User Functions, it is blank, as if it is not finding the udf file, yet that file is in the database directory.

After posting the previous message, I tried renaming the rr.udf file in the R and R folder and copying the udf that I have distributed with the app into the R&R folder. That seems to have corrected the problem with the Report Designer not be able to open the report.____Is it possible that the Version 8.1 and 10+ runtimes handle the search path for rr.udf differently? That seems to be the only explanation for what I have encountered.____If so, it would be helpful if you could explain how R&R handles it in each version.

In both versions, R&R will find the UDF file in the R&R program directory (where the designer/runtime exe lives) or if a link directory has been set (so that the LIC file and UDF file can be in a different directory than the EXE) then the UDF will be located in the link directory.__So the rules should be the same in both.____Kathleen__R&R Support

>In both versions, R&R will find the UDF file in the R&R __>program directory (where the designer/runtime exe lives)____What if both and R&R directory and an application directory with the rrwrun.exe file exist on the same machine. This is where 8.1 and 10 seems to behave differently.____ or __>if a link directory has been set (so that the LIC file and __>UDF file can be in a different directory than the EXE) then __>the UDF will be located in the link directory. ____I don^t exactly follow what you mean by the link directory and the LIC file. Right now, we have a folder under our application in Program Files for all of the Rand R files, runtime, udfs, rrw^s and the dbf free tables they read. ____
