/*++
Routine Description:
This function initializes the Base Objects dialog box with
current values and recommended values. This may be used for
both [APPLY] and [CHECK] operations.
For [CHECK] operations, the caller is responsible for greying
all controls in the dialog box (except the [HELP] button) and
making the [APPLY] and [CANCEL] buttons invisible.
For [APPLY] operations, the caller is responsible for making the
[OK] button invisible.
Current settings are placed in the module-wide current-setting
variables.
Arguments
ChangesAllowed - TRUE: Leave change controls enabled.
FALSE: Disable change controls.
Return Values:
TRUE - The dialog has been initialized without problem.
FALSE - A problem was encountered. A popup has been displayed
and the dialog has been ended.
