LooperSearch (Function)

Advertencia
A partir de la versión 27, LooperSeek se conserva por motivos de compatibilidad. Esta función ha sido reemplazada por LooperSearch.

Searches for a value in an attribute of a Looper control.

Note: To search all the attributes of a RepeatString Looper control, use the LooperSearchEverywhere function..

Ejemplo

// Counts the names starting with "SMI" 
// The first one
Index is int = LooperSearch(ATT_NAME, "SMI", False)
Cnt is int = 0
WHILE Index <> -1
	Cnt++
	// Next one
	Index = LooperSearch(ATT_NAME, "SMI", False, Index + 1) 
END
Info("There are " + Cnt + " names starting with 'SMI'")

// Finds the position of customer #1234
Index is int = LooperSearch(ATT_IDCUSTOMER, "1234")
// If this customer was found
IF Index <> -1 THEN
	// Positions the Looper control on the found customer
	LOOP_LOOPER1 = Index
	// Retrieves the name of the customer (ATT_NAME is an "attribute" of LOOP_LOOPER1) 
	// and assigns it to a Static Text control
	STC_CAPTION1 = " Information about " + ATT_NAME
END
