MsgBox_CountDown() - MsgBox with visual countdown

[GreenCan]

Edit 2: Complete rewrite of the function, simplified version using a single function and without use of GUICtrlSetOnEvent or AutoItSetOption. Correct centering of message.

Edit 1: Updated function to correct possible misbehaving AutoItSetOption.

MsgBox with Visual CountDown

Self-explanatory I guess...

Looks good, and seems to work.

I was of the understanding that Opt commands are set at compile time, and cannot be enabled/disabled multiple times throughout a program.  For instance, I'm betting that since Opt("GUIOnEventMode",1) call is the first one the compiler sees in the code, that option is stuck on, and not actually disabled by the subsequent Opt("GUIOnEventMode",0) calls.

Nope, that's an incorrect understanding.

OK guinness, but I think SlowCoder74 has a point here. Not so smart from me to change opt and assuming it is 0...

Hi SlowCoder74

As guinness already replied, you can change opt commands as many times as you like but I admit that changing opt in a function is not the smartest approach, I should have coded the udf slower and think how to do it correctly.

So I should have coded like this

First line:

Local $_GUIOnEventMode = Opt("GUIOnEventMode", 1)

Before RETURN:

Opt("GUIOnEventMode", $_GUIOnEventMode)

Return ...

I will change the example accordingly

There's another issue with the udf. I am not very satisfied with the message label which is right aligned.  If the message size changes, it runs into problem (not centered or don't fit), I split up the label message/counter to avoid flickering (by updating only the counter), but with annoying side effects.

Thanks

Read the help file. Opt returns the previous value, so record that and reset when the MsgBox function exists. Though as MsgBox is a blocking function surely GUIGetMsg() would be better suited?

That is exactly what I corrected.

Yes, absolutely.

[guinness]

Sorry, I skimmed over to quickly.

[GreenCan]

I rewrote the function. It is much simpler now.

Definitely getting better in your code writing.

ı think

 

Local $iWidth = 200, $iHeight = 100

to

Local $iWidth = stringlen($sMessage)*8, $iHeight = 100
if $iWidth<200 then $iWidth=200

auto size

Yes, looks better...

Is there a way to use this script to reboot a pc/server at the end of the countdown or when or if the ok button is selected???

Would this also be able to be deployed with a user logged in or no user logged in???

​Yes, of course,

Use Shutdown (2) - for other options, see help file

A MsgBox doesn't make sense if the user is logged out, but I guess it should be possible, for sure when the script is running and the desktop is locked by the user, the script just continues to run. After the timeout period, the PC will reboot.
