Restore Button Module Properties

What is the command that is used in the Module Properties History Tab to restore the value of an attribute with everything, including pictures and OLEs?

There is not a single command to do this. You have to loop through history entries, then use hr.oldValue to obtain the rich text of the attribute value before the change, then assign this value to the attribute. Look at the "History" chapter of the DXL help, as you need other history properties like hr.type, hr.attrName, etc. to find the correct history record.

Cheers,

Peter

OK, you asked for the command used in the Object properties dialogue box. This is likely

obj."Object Text" = richText hr.oldValue

but still you have to get the correct history record as written above.

Well I wonder what the perm

bool undo (History h, Module m)

will do then. Did not try it but I thought it was to undo a history entry. Regards, Mathias

Greetings,
I used this script to restore the data from the Object Text. Just for your reference.
This one worked for me, because there was only one change per session, so I was able to restore the data I wanted with no issues. If you need to be more specific you can add, date, time anything that might help you.

Thanks for the inputs, I really appreciated.

void restore_Object_History(Object o, int sessNum, string atName){
    History h
        for h in o do{
                if(h.sessionNo == sessNum && h.attrName == atName){
                        o.atName = richText h.oldValue
                }
        }
}
 
Object o = current
restore_Object_History(o,18660,"Object Text")

This one works too. Thanks!!!

void restore_Object_History(Module m, Object o, int sessNum, string atName){
    History h
        for h in o do{
                if(h.type != modifyObject)continue
                if(h.sessionNo == sessNum && h.attrName == atName){
                        //o.atName = richText h.oldValue
                        bool b = undo(h, m)
                        //print b
                }
        }
}
 
Module m = current
Object o = current
restore_Object_History(m,o,18660,"Proposed Object Text")

Nice! It's never too late to learn undocumented DXL perms :-)
