Hi,
I have created an application which uses a SQL server database. I created a
mainform which retreives all the customers. This takes about 3sec. I have
created a splash screen too. I use a module to open the splash screen and
then the mainform.
The splash screen opens up, mainfrom load, but still it takes 3sec for the
data to show up. What i want is while the mainform loads, i want to show the
splash screen.
Any suggestions.

Senthil,
Just this in the load sub of form1 is the shortest way of showing a handling
a splash screen I can think about. In this is not any error handling done,
so it will never be real just a here in this message types sample snippet.
\\\
dim frm2 as form2
frm2.show
datatadapter.fi ll(mydataset)
frm2.close
///
I hope this helps?

Herfried,
In this message is written "Should be" I disagree that very much, there are
hundreds of other methods which will give the same result with less work.
(Not denying that there are situation where a threaded form can help).
The method I showed is as well for dataaccess in the resource kit in a more
extended format. Therefore my question why you show such a difficult method
that "should" be used for a splash screen that normally would show so short,
that id does not give the time to read what is written on it before it is
closes again.

Notice that the user will be able to click the main form and thus send the
splash screen to back, if the form is already visible, or the main form
won't be visible at all until the splash screen closes and loading is done.

And what can be the problem than, (Think about it its loading of a dataset
or other dataclasses while the form is 3 seconds open, you can reach in that
time the close button of course, however most users don't).

I see a typo dim frm2 as form2
dim frm2 as new form2

Hi All,
Thanks for your replies. I found a solution to my problem:
Create this sub and add it in the form load event. but before loading the
dataset. We can increase the value of 3000 to more if it takes long for the
dataset to fill.
imports system.threadin g
Private Sub LoadSplash()
Dim m_frmSplash As New frmSplash
m_frmSplash.Sho w()
Application.DoE vents()
Thread.Sleep(30 00)
m_frmSplash.Clo se()
End Sub

Senthil,
Do you look to the answers in this newsgroup.
That threading.threa d.sleep with doEvents sample as you use it, is real a
very bad implementation to keep the program active and show the form.
You use now exactly the same sample as I gave you, only with one application
do events in it and let the program sleep 3 seconds even when the wait time
is half a second. How you synchronize that with the reading is a riddle.
I think it has no sense to give you the right implementation with
threading.sleep and doevents, because it seems you do not read this messages
anyway.

Hi Cor,
Not to offend, but i do read the answers. But the code you mentioned, doesnt
solve the problem, still the same behavious was seen. So i found another
example of a splash screen wherein this code was given.
To be honest with you, i am new to .net , dont know about threading, etc.
Since it really didnt do anything disatrous, i kind of let it go.
About the timing, i increased the value 3000 up and and down and thats the
setting it works,
Thanks all for your comments.

Any ideas on how I would get a splash screen to appear for a certain

I know about message boxes in VB but I don't my users having to click

Using VB in VS2005. 2005 has a new way to implment a spash screen that
alleviates the need for hardly any code. But I have found that when a
GUI that has a splash screen is run as a scheduled task, the splash
screen (and no other screen) is displayed for the entire run of the
application. How can I disable the spalsh screen just for when an app
is run as a scheduled task?

The form opens on project startup but closes immediately before anyone would

This is not long enough but I can't see how to slow it down.

Hi
In my app I have a SplashScreen, a login form and a main form. On launching
the app, I'd like to show the SplashScreen while reading config files and
attempting a database connection. I show progress of these tasks on a label
on the SplashScreen form.
Once this is completed ok, the splash screen should close and the login form
should be displayed. A successful login closes that form and shows the main
form.
