Thanks Bryan for the tip.

RE: Directory permission bitwise operation help needed
Thanks for the reply Lewis. What I am looking for is a lot less complicatedthan CFX-Permissions and also necessary to run on both Windows and Linux. I basically want to be able to set a permissions string for a user in the database and use a mask to test if a certain bit string is set. If it is the user has permission to perform a certain action Ex. 10101010 permission string 0010 mask 0010 user has permission to perform this action I just wanted to know if there was anything more involved in this other than just doing the above masking operation. I'm sure there is, but it's Friday and I can only think about the weekend right now. I'll also take a look at your custom tag and bug you if I have any questions. Thanks for your help.

RE: Directory permission bitwise operation help needed
Oh, that's a different story. If you are creating your own bit strings it's easy: Use constants in application.cfm to define what each bit means: cfset BIT_CANEDIT = 0 cfset BIT_CANVIEW = 1 cfset BIT_CANDELETE = 2 etc... Then you can check them using this: cfif NOT BitMaskRead(client.permissions,BIT_CANEDIT,1) relocate to DENIED page /cfif The only caveat here is that client.permissions must be an integer. If you want to store the bit string in the DB as a string then you'll have to convert it to an integer when the user logs in. Manipulation is also easy: start with a permission setting of 0 and use BitMaskSet(client.permissions,1,BIT_CANEDIT,1) to turn the bit on and BitMaskSet(client.permissions,0,BIT_CANEDIT,1) to turn it off Good luck! +---+ Bryan Love Macromedia Certified Professional Internet Application Developer Database Analyst Telecommunication Systems [EMAIL PROTECTED] +---+ ...'If there must be trouble, let it be in my day, that my child may have peace'... - Thomas Paine, The American Crisis -Original Message- From: Brian Ferrigno [mailto:[EMAIL PROTECTED]] Sent: Friday, June 07, 2002 12:53 PM To: CF-Talk Subject: RE: Directory permission bitwise operation help needed Thanks for the reply Lewis.
