<br>
<b>Description</b>
<br>
CheckBrowseMode is used internally by many dataset methods to ensure that modifications to the active record are posted to the database when a dataset's state is dsEdit, dsInsert, or dsSetKey state and the method switches to a different record.
<br>

<br>

If Modified is False, CheckBrowseMode calls Cancel.

<br>
If an application uses existing dataset methods, CheckBrowseMode is always called when necessary, so there is usually no need to call CheckBrowseMode directly.
<br>

<br>
Applications that provide custom dataset routines may need to call CheckBrowseMode inside those routines to guarantee that changes are posted to the database when switching to a different record.
