ForEach in Array Trick
Keywords: ForEach Tab delimited list array element loop
Question:
The new ElseIf statement makes me pine again for the ForEach statement like this that deals with lists and array elements.ForEach variable In list By delimiter
Answer:
One trick would be to convert your list to an array the loop through the elements in the array using ForEach.
strList = "a,b,c,d,e,f"
; Convert list to an array
arrA = ObjectType ("ARRAY", Arrayize (strList, ","))
intElements = ArrInfo (arrA, 1)
If intElements
intItem = 0
; Access each element in the array
ForEach arrElement In arrA
intItem = intItem + 1
Message (intItem, arrElement)
Next
EndIf
Exit
... or the short version ...
; Short Version.
ForEach strItem In ObjectType ("ARRAY", Arrayize ("a,b,c,d,e,f", ","))
Message ("",strItem)
Next
Exit
Here is an example that uses a UDF to convert the list to an array object.
#DefineSubRoutine udsListToVTArray (strList, strDelimiter)
Return ObjectType ("ARRAY", Arrayize (strList, strDelimiter))
#EndSubRoutine
strListColors = "red,green,blue"
arrColors = udsListToVTArray (strListColors, ",")
ForEach strColor In arrColors
Pause ("Color Collection", strColor)
Next
Exit
