Is there a DoEvents or equivalent instruction for easing the breakage of
loops? Also, if you substitute While Wend for your Do Until Loop can you
achieve the same result with your code???
TIA

Fatal exception as far as what? What is the rest of the error message?
Jason,
Does it blow up or just stop?

well this runs as expected
Dim bstop As Boolean = True
Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
Dim icount As Integer
Do Until bstop = False
'there's some code here
'etc, etc
Debug.WriteLine (icount.ToStrin g)
Application.DoE vents()
icount += 1
Loop
End Sub
Private Sub Button2_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button2.Click
bstop = False
End Sub
so the problem is probably in the part where there is some code :-)
you need doevents in this case to let the thread check the state of the
boolean
otherwise you would have an endless loop wich might also depending on the
code that is in the loop result in out of memory ( out of stack ) exceptions
or other unpredictable results :-)

Okay, trying to get the for...in loop syntax and obviously doing
something wrong.
I have a form and a select with options.
The explicit indexing I usually use works fine and alerts all the
values.
The for...in loop gives undefined for both IE and NN, but for IE, kills
it with way too many alerts. NN6 gives the right number of alerts (5
options, 5 alerts) but all say undefined.
Anyone know what I did wrong? AFAIK, selectElement.options...

I have a script with a regex
var re = /\/(\w+?)\//;
In IE5 Mac, that kills all javascript, anywhere on the page. No errors
but no functionality at all. Just the mere presence of that line without
it being called.
removing the "?", returns everything normal.

Never mind what they tell you. Just installed 2.0 beta and no more 1.1.
Tried to run simple ASP app and doesn't work anymore. Ran aspnet_regiss -i
but to no avail. So anyone who tells you they run side by side needs to be
put in the stocks with the spammers.
No I can only hope that a system restore will fix this.

I am trying to write an event-driven application with no main window that
runs "forever". It waits on a named event and then displays a window
depending on data pased in a memory-mapped file. I started with a standard
console application and it all works fine, except that it does not terminate
tidily when the user logs off/shuts down. So, I figured I needed a message
loop to pick up WM_QUIT. I studied the code in "Waiting in a message loop"...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
