Hi guys,
Our application takes some time to load.
I already tried some tricks like the suspend layout when loading combo boxes and only loading them when necessary etc. but it's still slow. Especially the first time. (because of JIT compiler)
A while ago there was a link here on CP to some article on the web that enables you to leave the JIT compilation, but I can't find it anymore. If somebody could point me out to that one, that would be great.
Any tricks you know to speed up the application is helpful, but we don't want too many code changes.
Thanks for your help!

Make a form that print 'loading...' and show it before your application run 
|

I recommend precompiling the application using NGen. This creates a native image of the application, this makes the application start a little faster and run a little faster.
Quick question: How many controls do you use on the form and is the form databound to a lot of datasources? Having a lot of controls on a form makes the application slower, especially when layering them using groupboxes and panels.
Also loading from a database the first time (and often after that too) makes the application slow. You can fake the user by loading the data using async methods. This makes the application more responsive.
There could be more tricks, but this is what I know at the moment.

That was the thing I lost. Thank you so much.
We don't have that many controls, but a lot of data is in them. The entire logic seems simple at the outside, but is very complex at the inside. That's why we loose so much time. Furthermore, on my laptop, speed is acceptable, but the client works on old(er) machines.
thanks for your help !!

Can I ask you a little question: I've found this article -> Ngen[^].
As I understand correctly it doesn't change anything in your exe, it just has a compiled 'image' in a service. this would mean I need to use ngen again if I install on another cpu. Here's my problem: The NGen tool comes with VS2005 and on the client machine we only have the framework installed.
So what did I miss?
again, tnx for your help!

NGen is part of the .NET Framework, not Visual Studio. For 1.1, you'll find it in C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.

I also have a question abour pre compilation. Doesnot we need to precompile on different hardware Configuration? A best Precompiled Image of assembly may not even good at your hardware?
Am I right? Or please give me some more info.
Best regards,

NGen generates binaries that are VERY processor specific. If you use NGen on a Pentium IV, the code won't work on a Pentium III.
NGen is best used during application installation. After the app is installed, you can have a Custom Action precompile any/all of your assemblies so as to reduce the startup time as much as possible.

Exactly this is what I was thinking of. Can you point any article that uses acustom action? Do I have to make a seperate application for precompiling it using System.Diagnostics.Process.Start()???
Best Regards,
Rizwan

This[^] is all I know of. And no, you don't have to write a seperate application to do this. You can include the code in the custom action.

Thanks, I check it

Yup, you need to precompile the application every time its installed on a different computer.
This is best done during setup. There should be custom actions for it on the internet.

Hi,
I created a project to teach myself C#/VS2003 and have now found that after a couple of months AND upgrading to VS2005 that I would like to clean it up and get rid of all the mistakes/junk/bad coding that I did during the early days  .
What I want to do is create a new project in VS2005, get the basic display right and then copy most of the original code pages into the new project.
I know how to copy accross the "old" .cs code files and guess I can then do a replace of the references to the old namespace to integrate these into my new project.
Is this the best way to go about it or is there a better/easier way to do this. Are there any pitfalls/dangers to watch out for.
Comments on your past experiences/suggestions will be most welcome.
Thanks,
Glen Harvy

I'd say just to start over. Create your new project and write the code again using the lessons you have learned. If you just copy the files you'll still have all the mistakes/junk/bad code to deal with.

Hi,
I have set SQL Express as pre-requisite of my C# Windows application. Now what happens is that whenever i install my app., it installs SQL Express even if SQL Server 2005 or SQL Server 2000 is installed on the target machine. If SQL Express in already installed, then it does not install it. I dont want SQL Express to be installed whenever any of SQL Server 2005 or SQL Server 2000 is installed on the target machine. Please guide me how can i do that?
Regards,
Wasif Ehsan.

You need to write a custom action in your installer to check for the presence of SQL Server then either install SQL Express or not.

hi 
who knows, what dll is better to use for an application wich needs to perform some ftp actions. i found BytesRoad.Net but it's too slow, and also ComponentSpace.Ftp, but it's 30 days trial...tahnks

There is a libraty Called LumiSoft.Net[^] (The library does A LOT more than the article shows.Lastest version Here[^] ) wich has both FTP Server & Client implementations on it.
Also, you can use "FtpWebRequest" (.Net 2.0) to manage FTP operations.
