Re: forms 4.5 help wanted quick!!

Elaine,

Question 1: No. On Windows 3.11 and Win95, button color attributes are controlled by the settings in Control Panel.

Question 2: Potential master blocks are those blocks whose base table is referenced in a foreign key constraint by the current block's base table. If the constraint is not defined in the database, then no blocks will be listed as potential master blocks. However, as you discovered, you can create a relation in the Object Navigator without the constraint being defined in the database.

Question 3: It sounds like you have the master block and detail block on different canvases. If so, then the detail block's canvas will not be displayed until you navigate to it.

Question 4a: Yes. Use the ENTER_QUERY built-in.

Question 4b: When you're in Normal mode, the ENTER_QUERY built-in puts you in Enter Query mode. When you're in Enter Query mode, the EXIT_FORM built-in returns you to Normal mode.

Question 4c: When the New Block window is used to create a block, any field with a primary key constraint gets the "Required" property set to True. This is why Forms will not let you exit until you have entered some data. I recommend setting this property to False for all items, even primary key and other required fields, because often a user will navigate to a screen erroneously and want to immediately exit. The Required = True condition prevents this. A When-Validate-Item trigger or When-Validate-Record trigger can be used instead of Required = True to ensure that required fields are not left blank.

Question 5: At runtime, select Keys from the Help menu, and a dialog box showing all the function keys will be displayed.

Question 6: Not that I'm aware of.

Hope this helps.
