Syntax
<Result> = Count(<Search control>)
<Result>: Integer - Number of controls with the same name found in the window or in the page.
- Number of controls found in a group of controls.
- 0 if the control does not exist.
<Search control>: Control name or character string Name of the control or name of the group of controls.
If this parameter corresponds to an empty string (""), it is automatically replaced with the name of the control to which the current event belongs.
For the indexed controls, there is no need to specify the subscript. Remarks Invisible, inactive or grayed out control An invisible, inactive or grayed control is considered as being found in the window or in the page. Caution: A control must not be directly used in a process where its existence is checked. A runtime error will occur if the control does not exist. Example (of what not to do): IF Count(EDT_Control1) > 0 THEN
EDT_Control1 = "Foo"
END
Example (of what to do): IF Count(EDT_Control1) > 0 THEN
