Hi,

I have created a webservice from PB 12.5 Classic.

Webservice got a function that receive some parameters, retrieve data from DB in a datastore and then save ds as a pdf file (in C:\temp\PDFs\) and then return name and path of file created.

From Asp.Net MVC i call webservice and then i receive path and name of new file.

Problem is that everything works fine but save ds as pdf file.

I got installed GS and a printer for creating PDF

Any idea about this error and solution?

This is the code in NVO (always return ERROR_-2):

dataStore ldst_report
string ls_dataobject, ls_filename, ls_path, ls_filenameguid
long ll_rows, ll_return

this.of_populatedbparm (as_server, as_database, as_user, as_password)

if not SQLCA.of_isconnected( ) Then 
    
    IF SQLCA.of_connect( ) = -1 Then             
        as_filename = "ERROR_-1 "
        Return
    end if
    
end if

ls_filenameguid = as_filename

as_filename = "ERROR_0"

ls_dataobject = as_report + "_" + as_language
ldst_report = CREATE dataStore
ldst_report.dataObject = ls_dataobject
ldst_report.SetTransObject(SQLCA)
ll_rows = ldst_report.Retrieve(al_centroid, as_sqlwhere, as_userid, as_rolename, as_applicationname, as_sqldateformat)
al_rows = ll_rows

0 Then
    
    ls_path = "C:\temp\PDFs\"
    ls_filename = ls_filenameguid + ".pdf"
    ls_path = ls_path + ls_filename
    
    ldst_report.Object.DataWindow.Export.PDF.Method = Distill!
    ldst_report.Object.DataWindow.Printer = "Sybase DataWindow PS"
    ldst_report.Object.DataWindow.Export.PDF.Distill.CustomPostScript="No"
    
    ll_return = ldst_report.SaveAs(ls_path, PDF!, TRUE)    
    as_filename = ls_filename
    if (ll_return 1) Then as_filename = "ERROR_-2 " + ls_path
    
End If

DESTROY ldst_report

SQLCA.of_disconnect( )
