Reducing app start-up time

[John]

Hi

I am looking to reduce app loading time. My question is, if I use the splash
screen feature from App Properties->Application->Splash Screen does it add
to the app loading time and am I better of running the splash screen using
the background worker?

Thanks

Regards

Heya,

splashscreen is running in separate thread, so there is no need to and
it wont slow down your application. Only problem can be either when
you run your application on terminal services\citrix (you shouldnt use
transparency in that case) and sometimes I noticed that splashscreen
stays on screen even when main form was already initialized (for one
or two seconds).

If you think that your application appears to be slow (we all know
that if use see something moving, even if application load take same
amount of time, they will forgive you), I would recommend to implement
some busy bar (continuous progress bar). You can find few at
CodeProject, I am using BusyBar.dll

Are you loading a dataset somewhere in the load event of the application.

I recently read - since the db has constraints on, the initial fill does not
need to check constraints on the db on the initial load (for each record) ,
so you can do something like this
<written in notepad>

Dim ds As Dataset
Dim daTemp As SqlDataAdapter

ds.EnforceConstraints = False
daTemp.Fill(ds.Tables("Table1"))
dsEnforceConstraints = True

Take note how you turn it on after the fact.
By default it is turned on, but it takes overhead to preform the constraint
on the fill object.
If the database has proper db constraints on it, you can be sure you are
getting proper data already from your db that has already validated all your
initial data for you.

-Just a thought - if something like this may be slowing you down.
