Tevfik: I see from your experience that you have Visual Basic. I'm attempting to develop a file deployment/synchronization application using the cwRsync product in a VB 6.0 environment. It will run continuously on a Win box and need to communicate with both Win and UNIX clients. Is this possible? I inferred that I only needed to run the cwRsync install, which did install the rsync server service on my XP box. I then attempted to add References to the 2 DLLs that came with the download, but I received this error when I attempted to Register cygwin1.dll, " ...was loaded, but the DllRegisterServer entry point was not found. DllRegisterServer may not be exported, or a corrupt version may be in memoyr. Consider using PView to detect and remove it." The registration of cygpopt-0.dll was successful. Do you have any suggestions? I also downloaded these other products from your site thinking that may provide additional features to this application, especially regarding encryption and remote password management: - copssh_1.2.0_Installer.zip - chwinpw-1.0.zip Ross Walker --------------------------------- Do you Yahoo!?
