Long Process

[John Wright]

I have a long process I run that needs to be complete before the user can continue. I can change the cursor to an hourglass, but I want to update the Status Strip on the bottom during the process. I set the statusstrip label to "Downloading... ", but it will not show up on the form. I need to display this message before it starts the process. I can put a thread.sleep for 1 second after I do the initial process, but that seems sloppy to me. Any suggestions? Here is my code launched from a button click:
'update the label--This does not show because the process starts before the UI updates
slDBList.Text = "Retrieving Databases..."Tr yMe.Cursor = Cursors.WaitCur sorDim lstServers As List(Of String)'set to false in case of an error boolServersLoad ed = FalseboolDBLoad ed = False'clear the servers list cbServers.DataS ource = Nothing'clear the databases list dbDatabases.Dat aSource = NothingIf chkSort.Checked = True ThenlstServers = GetSqlServers(T rue)ElselstServ ers = GetSqlServers(F alse)End IfcbServers.Dat aSource = lstServers'set to true to enabled the selected index change on the dropdown boolServersLoad ed = TrueslDBList.Te xt = ""Catch ex As ExceptionMessag eBox.Show("Erro r loading server list.

Armin,

To write something more, maybe you remember that I 5 years ago wrote a
message just to prettend that somebody could told that he got the advice
from somebody in the newsgroups, while the result of that could be go wrong.

That was the only reason of my message.

>>Joergen,

Be aware that you never should do what you advice as it is a
critical process that has to be completed, and the user can end that
in the middle without knowing what is the effect.

Think by instance in a paying process by banks, were steps have to
be done, I would never be the one who would give an advice as yours.

Just my idea,

Cor

Like Joergen, I don't understand this plea. Using another thread to avoid
the UI thread being blocked is the (only) right action, IMO. But maybe
you meant that the UI thread also have to be in an appropriate state
depending on the whole situation, where I would agree.

If DoEvents should not be used any more, why is it in the language?

Legacy code support.

That's the quickest way to get a control updated. Works just fine. This
is the first I have heard about it not being valid any longer. Does
Microsoft know about this?

Just as GoTo is the quickest way, in terms of code, to branch to another
part of your sub or function. It's still included even in VB 2008.

I wouldn't recommend using it, anymore than I'd recommend using DoEvents
though ;-)
