Re: VFP9SP2 order of objects issue
I do not expect any object on the form to exist until the form gets to its INIT method. According to the order in which events fire, all contained objects instantiate (ie exist) _before_ the form init. You can test this by placing code like this in the init methods of the DE, the form and all contained objects: DEBUGOUT "label1 init" DEBUGOUT "form init" etc You can also put that code in the load,destroy and unload events of the form, the valid, keypress,lostfocus, etc of all contained objects. Just create a test form and put the debugout keyword with a text indicating what event is firing and run the form. The debug window will open and you will see in writing how each event is firing. You will notice that all contained objects init events fire before the form's init BTW, I use a form like this every time things do not happen the way my logic says they should and oftentimes I am proven wrong.

RE: VFP9SP2 order of objects issue
I also thought that Tab Order should resolve your problem - I find it strange that it doesn't.

Re: VFP9SP2 order of objects issue
Ellaborating on Alan's code, I imagine something like this: Init event of all labels: this.addproperty(´lInstantiated') In the TOP labels: this.lInstantiated = .t. In the BOTTOM labels this.lInstatiated = .f. if this.lInstantiated dodefault() ** here goes your special code else nodefault endif If the property is false, the label would not instantiate, because of the NODEFAULT clause In the case of the TOP labels, lInstantiate would be true, therefore the dodefault() code would run and they should instantiate first. After all of them instantiate, you can set the lInstantiated property to .t. in all labels for i = 1 to thisform.controlcount if lower(thisform.controls(i).class) = 'label' thisform.controls(i).lInstantiated = .t. endif endfor thisform.refresh If my thinking is correct, the TOP labels would instantiate first, and then would instantiate the rest of them. But I never did something like this, so I might be wrong ( I really never fooled around with nodefault) BTW, why would you play with labels values like that, I'm curious? Could you not set the value of your properties in any other way? Rafael Copquin El 08/11/2012 04:01 p.m., Alan Bourke escribió: I'd say you might be better examining the whole approach.
