/////////////////////////////////////////////////////////////////////////////
// Name:        dialogs.cpp
// Purpose:     updating to make it more relevant to my code
//              and more similar to my code.
// 
//              Leaving most of useless to me examples in place
//              unless I am completely sure they are will never
//              be useful.
// 
//              Some of the stuff here does not quite work
//              Only half implemented.  Eg, log message
//              The primary child of Frame is a scrollable
//              window "MyCanvas" to which nothing ever gets
//              written after it is created.  And the tip
//              of the day dialog fails sould be under help)
// 
//              On the other hand, lots of cool bits of code
//              that really deserve to be copied, like 
//              hooking the windows system menu of 
//              a window.
