How can I get the identifier of a given control, which is part of a predefined 
windows dialog such as open/ save dialogs? I need to alter text in the edit control 
and/ or alter captions on buttons before the dialog closes. Can this be 
accomplished with API calls and/ or messages to the dialog in question?

Answer:

With WinSight for example. Anyway, there are some of them (Open/ Save dialog 
controls ID's):

"Look in" - ID 1137 , classname "ComboBox"
"Files of type" - ID 1136 , classname "ComboBox"
"File Name" - ID 1152 , classname "Edit"
"Help" - ID 1038 , classname "Button"
"Open" - ID 1 , classname "Button"
"Cancel" - ID 2 , classname "Button"
"Open as Read only" - ID 1040 , classname "Button"

The usage - for example, to alert the text of "File name" Edit - is like this:

1   { ... }
2   var
3     MyText: string;
4   begin
5     MyText := 'Hello!';
6     SendMessage(Windows.GetParent(Self.Handle), CDM_SETCONTROLTEXT,
7       1152, Integer(PChar(MyText)));
8     { ... }
