Battle of The Flickering Label

Recommended Posts

TheCrimsonCrusader

Greetings,

I know there are several threads regarding text label flickering, but I am just not getting it apparently. 

In the script I have provided, I want to constantly poll for the IP address and update the text label anytime it changes.  I know I can simply change the sleep time in the loop to virtually eliminate that problem, however, later on, I will be adding a clock and other items and those labels won't be precise enough (particularly the clock) by adding additional sleep time.

Logically, I was trying to code it where if the IP address isn't the same as it was, then and only then update the label as well, but that wasn't working out for me either, so I was missing something there as well.

Any suggestions would be greatly appreciated and thanks in advance!

 

#include <GuiConstants.au3>


;Create GUI
GUICreate("Test GUI", 400,300, -1, -1, BitOR($WS_DLGFRAME, $WS_EX_TOPMOST), 0)


;Create label titled "IP Address"
GUICtrlCreateLabel("", 2, 185, 193, 38,$SS_ETCHEDFRAME,$WS_EX_DLGMODALFRAME)
GUICtrlCreateLabel("IP Address:", 10, 195, 176, 18)
GUICtrlSetFont (-1,-1, 800)


;Create label where current IP address will be displayed
$IPAddress1 = GUICtrlCreateLabel("", 195, 185, 193, 38,$SS_ETCHEDFRAME,$WS_EX_DLGMODALFRAME)
Global $IPAddress2 = GUICtrlCreateLabel(0, 208, 195, 166,18,$ES_READONLY, $WS_EX_TRANSPARENT)


;Show GUI
GUISetState(@SW_SHOW)


;Start loop to call set GUI label data by calling IPAddress function
while 1
    Sleep(10)
    GUICtrlSetData($IPAddress2, IPAddress())
Wend


;Update IP Address label
func IPAddress()
   Return @IPAddress1
EndFunc

This works.

Thanks, BrewMan!  That works (just need to throw different IP change scenarios against it) and what you added there makes complete sense now after seeing it.  Kind of like the puzzles in the Myst series. :-)

Learned it long ago, glad I could pay it forward.
