WinForm app speed issue - Visual Basic .NET

John

Hi

I have a multi-form winform database application. The client keeps
complaining that application runs too slow 50% of the time. The problem
seems to be in two areas;

a) app is slow maximising after a prolonged period of being minimised.

b) when user clicks on a toolbar to select one of the several already open
forms.

This seems to suggest that there is nothing wrong with application per se as
application works fine 50% and also maximising app or moving from one open
form to another open form does not do anything special code wise. Also as
other non .net apps run just fine on the same pcs, this can't be due to spec
of pcs. I have also ngen'd the app using command line 'ngen install
myapp.exe'.

I am therefore wondering what can be causing this slow response and would
appreciate any help in ironing out this speed issue.

Many Thanks

Regards

Maybe, your problem is the use of those 3rd party tools. Maybe, you should
be talking to Infragistics about speed issues using their controls.

Have you run a profiler tool to identify the areas that are causing your
slow down?

Winform vs Webform: how to choose?

by: Dean Slindee | last post by:

I would like to hear some practical comments about how to decide whether a new application becomes a Winform vs a Webform application. Would you say that every app should be, by default, a Winform app unless it positively cannot be (for some technical reason). Or vice-versa? Obviously, Visual Studio could never be a Webform app because it requires a lot of CPU cycles. It appears to me that there is a broad sort of continuum in...

help explain this winform behaviour

by: dadizhu | last post by:

Hi, everyone. I ran into an UI freeze issue with threading and simplied the problem down to the following sample code. The logic is as follows: 1. The main UI thread creates a non-UI STA thread(m_MainThread). 2. Then the non-UI thread runs and creates derived winform and holds a reference to the winform. NOTE: I don't call Application.Run() because I don't need a message pump on this "hidden form" in my application. I rely on the...

WinForm sizing problem in different computers

by: lamxing | last post by:

Hi, I've come across a strange problem with the WinForm's sizing. I've designed a WinForm and it runs fine on my computer and some other PCs. But when I was trying to run the app under some PCs with wide screen, some of my controls on the WinForm will automatic resize themselves to be bigger and thus push other controls off the screen. For a sample of this problem, please see http://usctimes.com/screen.jpg .. The screen on the left is...

Showing a winform in Excel is slow the first time

by: Torben Laursen | last post by:

I have a COM shared add-in written in C# that I use in Excel. One of the thinks that the user can do is to open some winforms. The problem that I have is that the first time the user opens a winform it is slow around 7 seconds and after that it takes no time. Is there a way to speed up the process to show the winform the first time? Thanks Torben
