pcsoft.us.windevCopyright 2026, PC SOFT1 Nov 2017 19:36:00 Z1 Nov 2017 19:36:00 ZWD21 Within my application I have a window which is used for all reports and contains all code and controls for running and filtering the specific report displays. Results of each report are displayed in table control - there are 12 of these sitting on individual planes and formatted to suit the output requirements. This has been working without problems for well over 3 years in versions 19, 20 and for the last 9 months in 21. Recently 2 new reports were added and since then random fatal errors have been encountered. These happen at different times on different machines and across all (20+) reports. Once the user has re-opened the app all reports run without any reported issues. The only commonality I can see is that the reported error code is 3103 is thrown as a result of 'wMDIReportSuite_2' - the window above - being unknown. Recent Example..... WL call: Process of 'Method pOpenMDIWindow' (clsApplication.pOpenMDIWindow), line 13, thread 0 'ExecuteProcess' function, syntax 0 What happened? 'wMDIReportSuite_2' component unknown. An application must be compiled with the component. I have recompiled, repaired and regenerated the exe without any improvement. Anyone have any idea of where I might look to isolate and rectify this issue.
