Get name item definition (label) with a loop (for)

Hi all :)

A my friend asked me if is possible get a name of a label and change the label string with a loop. I have try this code:

rollout Test "test" width:100 height:200
(         
label temp1 "hello1"         
label temp2 "hello2"         
 
on Test open do         
(                  
for i=1 to 2 do                  
(            
local namelabel = "temp" + i as string                           
namelabel.text = "changetext" + i as string                  
)          
)
)
createDialog Test

I have always the same error : Unknown property: "text" in "temp1"

How to access the item definition (temp1/temp2) of label then update the value string ? I can do this?

Thanks for any help

hey again :)

just small thing:

You need to format it and execute it :)

(
try(destroyDialog ::Test)catch()
rollout Test "test" width:100 height:200
	(         
		label temp1 "hello1"         
		label temp2 "hello2"         
 
		on Test open do (                  
			for i=1 to 2 do                  
				(            
					local str = stringStream ""
					format "Test.temp%.text = \"%\" + % as string" i "changetext" i to:str     
					execute(str as string)
				)          
		)
	)
createDialog Test
)

It should works now,

One more example

try(destroyDialog ::Test)catch()
rollout Test "test" width:200 height:100  
(         
		local lblNames = #("John", "Stalone", "BruceLee", "HELLOOOO", "ZZZZzzzz", "Michael", "71")
		label temp1 "hello1"  width:100 height:20 style_sunkenedge:on       
		label temp2 "hello2" width:100 height:20  style_sunkenedge:on        
 
		button btn "Random Names" width:150
		on btn pressed do for i = 1 to 2 do test.controls[i].caption = lblNames[random 1 lblNames.count]
)
createDialog Test
)
