About the CREATEOBJECT Command
Any form object can be created at runtime, simply by knowing the exact Control Type, Component ID, parent (form or any control having the option of a container, and coordinates (Left, Top, Width, Height).
To place Database Control objects, you'll need to provide additional parameters, such as, Table Name, Field Name. For Variable Objects, you'll need to provide associated variable name. And, once the object is defined, it is required to initialize the object in order for the object to be placed on the form. All of the definitions for the newly created object are performed using the PROPERTY Command.
Use the Data Dictionary to browse the list of form Control Type and to easily insert the values into your command files/applications.
Order of Processing To Create an Object
The order of processing for the CREATEOBJECT command is as follows:
1.Use the CREATEOBJECT command to create the object.
2.For Database or Variable controls, use the PROPERTY command to assign the database field or Variable name.
3.When inserting Custom EEPs, use the PROPERTY command to assign the Custom EEP command syntax.
4.Use the PROPERTY ComponentID INIT 'TRUE' command to initialize the object.
5.Use the PROPERTY command to set any additional characteristics, like color, font, background, etc., that would be specific to the type of object you are creating.
Notes:
•A form must include the associated Master table, unless a variable form is being created.
•Any additional form related tables MUST be defined using the form designer.
•To delete an object on the fly, use the DELETEOBJECT command.
Examples
-- Place a text caption for the field (ObjectType: StaticText)
CREATEOBJECT StaticText 'StaticText1' 'RBASE_FORM' 10 10 400 20
PROPERTY StaticText1 INIT TRUE
PROPERTY StaticText1 CAPTION 'Dynamically Created DB Controls'
-- Place a Panel on the Form (ObjectType: Panel)
CREATEOBJECT Panel 'Panel' 'RBASE_FORM' 10 40 400 120
PROPERTY Panel INIT TRUE
-- DB Edit Control Based on Table: Customer, Column: CustAddress
CREATEOBJECT DBEdit 'DBEdit2' 'Panel' 100 35 220 20
PROPERTY DBEdit2 TblName 'Customer'
PROPERTY DBEdit2 FldName 'CustAddress'
PROPERTY DBEdit2 INIT TRUE
PROPERTY DBEdit2 FRAMEVISIBLE TRUE
-- Place a DB Navigator Control Based on Table: Customer
CREATEOBJECT DBNavigator 'Navigator' 'Panel' 100 90 200 20
PROPERTY Navigator TblName 'Customer'
PROPERTY Navigator INIT TRUE
PROPERTY Navigator IMAGESTYLE 'Razzmatazz'
PROPERTY Navigator FLAT TRUE
-- To insert Custom EEP command syntax into the "DBEdit2" Control defined above
-- PROPERTY ComponentID 'Custom_EEP->YourCustomEEP' 'YourCustomEEPText'
CLEAR VAR vCommand1
SET VAR vQuote = (CVAL('QUOTES'))
SET VAR vCommand1 TEXT = ('PAUSE 2 USING'&vQuote&'This is the Address'&vQuote&';RETURN')
PROPERTY DBEdit2 'Custom_EEP->OnClickEEP' .vCommand1
RETURN
