...there I was just minding my own business when suddenly the toolbox blew
up in my face.
Could I have a round of "yes ModalDialog works as advertized" back at me.
I can't for the life of me figure out why the following code kills me with
error message #2.
begin
myDialog := GetNewDialog(DResNum,ADR(dRec),NIL);
repeat
ModalDialog(NIL,Item);
until Item = 1;
end
It works fine if you comment out the call to ModalDialog. By working fine, I
mean that resource dialog DResNum is drawn and it patiently waits forever.
Otherwise the dialog gets halfway through being drawn and KABOOM!
help!

BUT, please note that the behind parameter should be -1, not NIL. When all else fails, read the manual (Inside Macintosh) carefully.

It goes like this: begin dialogP := GetNewDialog(whichDialog,NIL,pointer(-1)); . . repeat ModalDialog(nil,dItem); . . As you can see, our calls to ModalDialog are essentially identical. The difference must be in the GetNewDialog call. The differences there occur in where the dialog is stored and which window it appears behind. You have chosen to provide space for the dialog. The NIL in my code places it on the heap. Although I'm not positive, if the address you provide is not on the correct boundary, you could get error 2. The other difference is that you use NIL to indicate where you want the dialog drawn. IM specifies the pointer(-1) in order to put the dialog on top. I hope this helps.
