Hi, I am trying to adjust the volume with fmod library. Downloaded the wce4 (375ce) dll file and added it with Tools->Components. After OK, I got a message saying "An error message cannot be displayed because an optional resource assemblycontaining it cannot be found, Continue?". By searching this forum, following that "error messages on device" post. With the cab file in System_SR_ENU_wm.zip installed , I still got an error message "File or assembly name "\SD Card\My Documents\fmodce.dll", or one of its dependencies, was not found.", no mater I put the file in the source file's directory or basic4ppc' installation directory. But choosing basic4ppc's lib "System.data.SQlite.dll", everything looks fine. The version info checked with File->Help->About is "Version 6.50, .Net Version: 2.0.7045". OS: wm 6.0 classic So, is this a compatibility problem for fmodce.dll with the new version, or something else caused the error? Thanks!
