<< I am attempting to get several files checked with a dll and display the results. RBase process’s sometimes one or two command lines. At least always one command line then it stops. It is still running in the background but it will run hours. Tried it in 7.6 latest and 9.0 >>
Could you post the code? Are these custom DLLs? If so, the problem is more likely to reside in the DLL itself. Does the DLL provide a debugging mode that can show you whether it's been called and/or has returned, and what it's doing? -- Larry
