Highest Image File ID
Can anyone think of a quick way (other than a repeat loop) to determine the highest ID of all the image files in a stack? Since I have a datagrid, the assigned ID is way up there and I want to keep my image files in sequence. It would be great if there were a command to get ALL the objects of a stack or card as an array. Even if there were a way to get all the objects, I could use a filter command to get the ones I wanted.

The ID of the stack is the either the last-used ID or the next available one, I forget which. It doesn't discriminate between the kinds of controls though. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Highest Image File ID
Maybe get the ID of the last image of stack xyz? Not sure if that would work or not, I seem to remember having problems with using the last keyword in the past but I think that was specifically to do with groups.

Re: Highest Image File ID
Yup. And I want to reuse all those wasted ID's that the Datagrid left behind. I am writing a function using repeat loops and if I lock screen and messages it is quite fast. I Will post it when I am done for anyone who might find it useful. Bob On Mar 21, 2012, at 9:49 AM, J.

Re: Highest Image File ID
I just did this: put the ID of the last control and it worked a charm. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: Highest Image File ID
Thanks Richmond and Pete. What I want it for is to set the ID of the image I just created to theHighestID +1. Obviously, if I just created an image, those functions will return that image ID. As promised, I have written a function that I think is fairly bullet proof. It checks for an invalid object type, as well as handling singular or plural forms of object types. It returns a sorted list of whatever property for whatever object type you tell it, excluding duplicates. I will probably enhance it to accept a scope, either card or stack. I'm wondering if this would be more useful to others if each line was a list of the long ID of the object followed by the property value? eg. put objectList(buttons, short name, descending) into theButtonNames function objectList theType, theProp, theSort if the last char of theType is s then put char 1 to -2 of theType into theType if theSort is empty then put ascending into theSort if theSort is not in ascending.descending then return Error: Invalid sort end if try do get the theProp of theType 1 of this card catch theError if item 1 of the last line of theError is 166 then return Error: Invalid type else return Error: the last line of theError end if end try put empty into theObjectList put 1 into theLineNum put theType s into thePluralType put the name of this card into theStartCard lock screen lock messages repeat with theCardNum = 1 to the number of cards of this stack go card theCardNum try do put the number of thePluralType of this card into theTypeCount repeat with theObjectNum = 1 to theTypeCount do put the theProp of theType theObjectNum into theValue if theValue is not in theObjectList then put theValue into line theLineNum of theObjectList add 1 to theLineNum end if end repeat catch theError breakpoint end try end repeat go card theStartCard if line 1 of theObjectList is a number then do sort theObjectList numeric theSort else do sort theObjectList theSort end if return theObjectList end objectList On Mar 21, 2012, at 10:07 AM, Pete wrote: Maybe get the ID of the last image of stack xyz?

Re: Highest Image File ID
Okay I updated the function to return an array to account for properties that are in array form. It returns a numbered array with two keys, the long ID of the object, and the property of each object you passed as an argument. I had to remove the sorting though because I am not about to sort an array. So far as I know sorting does not work with arrays. There should be some kind of form of sort for arrays like: sort the keys of myArrayA by myArray[id] of each -- or maybe by element 2 of each but of course there is not. At any rate sorting arrays is too much trouble, and I digress. Here's the updated function: function objectList theType, theProp if the last char of theType is s then put char 1 to -2 of theType into theType if theSort is empty then put ascending into theSort try do get the theProp of theType 1 of this card catch theError if item 1 of the last line of theError is 166 then return Error: Invalid type else return Error: the last line of theError end if end try put empty into theObjectList put empty into theObjectListA put 1 into theLineNum put theType s into thePluralType put the name of this card into theStartCard lock screen lock messages repeat with theCardNum = 1 to the number of cards of this stack go card theCardNum try do put the number of thePluralType of this card into theTypeCount repeat with theObjectNum = 1 to theTypeCount do put the long ID of theType theObjectNum into theObjectID do put the theProp of theType theObjectNum into theValue if theValue is not in theObjectList then put theObjectID into theObjectListA[theLineNum][LongID] put theValue into theObjectListA[theLineNum][theProp] put theValue into line 1 of theObjectList add 1 to theLineNum end if end repeat catch theError breakpoint end try end repeat go card theStartCard return theObjectListA end objectList The results for a call like put objectList(images, short name) into theArrayA returns a result (in printKeys() format) like this: 1 short name: imgLogonsHi LongID: image id 10101 of card id 1002 of stack /Users/bobsneidar/Documents/LiveCode Stacks/Conference Scheduler/CSL Main.livecode 2 short name: barpattern.png LongID: image id of card id 1002 of stack /Users/bobsneidar/Documents/LiveCode Stacks/Conference Scheduler/CSL Main.livecode snip ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
