Count (Function)

In french: Occurrence

Not available

Returns the number of occurrences of a control in a window, in a page or in a group of controls.

Example

// Initialize the EDT_Label control if it exists
IF Count(EDT_Label) > 0 THEN
Display_Label()
END

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.

Miscellaneous

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
