I am writing a program which installs resources into files. Suppose I have the following code: procedure InstallResource; var MyHandle : Handle; begin MyHandle^^ := {Whatever data to be put in the resource} AddResource (MyHandle, rsrcType, rsrcID, rsrcName); {...etc....} end; As I understand it, I use DisposHandle to get rid of one of my own handles, but I use ReleaseResource to get rid of a resource. Assuming that I have written my code as above, should I now say "DisposHandle(MyHandle)" or "ReleaseResource(MyHandle)"? If I want to stop treating it as a resource, should I DetachResource it, or is it already not a resource? If it is a resource, do I have to explicitly call UpdateResFile (or WriteResource) before releasing it, or does calling ReleaseResource automatically write it out? Thank you! --Kurisuto un020070@vaxa.wvnet.edu

My habit is to wear suspenders, and belt, AND lead-lined undershorts just in case the first two fail. Yes, your handle is now a resource handle. Call WriteResource, and UpdateResFile. Then, you can DetachResource if you want your copy back. =Ned Horvath= ehorvath@attmail.com
