Registering application to receive specific data type.

[York Kie Tan]

Hi, my application currently uses ExgRegisterDatatype() function to register 
to receive files of a certain extension (.jpg) and 
ExgSetDefaultApplication() to make it the default application to receive 
that file type. The problem is there are other applications that changes the 
"default application" (to themselves) when they are started. So, my question 
is, is there a way to prevent other applications from overriding the 
"default applcation"? If not, is there anyway to know when a change of 
"default application happens?

I will really appreciate it if someone can help, cos this problem is 
affecting the usage of my application. Thanks

York Kie

    When you wake up with hard key, you have vchrHard? key in event queue.
Modal event loop inside FrmAlert process this key and run application. You
can flush queue (be aware, the can be vchrResetAutoOff for OS5) or change
alert form to attention manager notification.

Check keyMask and event queue.
