Re: Compiler/Interpreter leppie30-Jul-04 8:19 leppie 30-Jul-04 8:19  all the code is compiled. when is a different story. C# source behind file are compile in the dll, but aspx and controls are compiled on 1st access, hence the reason u can replace them at runtime. Building a ASP.NET dll is a bit more tricky, and beyond the scope of normal human beings (but its all compiled) top secret xacc-ide 0.0.1 Re: Compiler/Interpreter softp_vc1-Aug-04 17:26 softp_vc 1-Aug-04 17:26  i cant get ur point. somebody told me that ASP.NET pages are interpreted while aother applications are compiled.

How to prevent paper being ejected when printing using PrintDocument? rahmadid29-Jul-04 18:26 rahmadid 29-Jul-04 18:26  Hi, How do I prevent the paper being ejected when printing using the PrintDocument object? Everytime the PrintPage event handler exits, the printer starts the printing and then ejects the paper immediately. I still need to print some text in text mode (not graphic) after that using my own library. I already set the PaperSize property but it doesn't do any good. Or is there a way to print in graphic mode without using PrintDocument? Thank you very much. Wierd memory leak on xeon processors Ægidius Ahenobarbus29-Jul-04 12:01 Ægidius Ahenobarbus 29-Jul-04 12:01  I have a memory leak problem. My remoting server runs on my development machine (2 1 Meg processors) at about 38mb However when I run it on the target machine (2 2.5 Meg Xeaon processors with hyperthreading) its memory usage ramps up and up. The only difference I can think of is the hardware architecture. Has any one got any bad experiences using multiple xeon processors? (OS is win 2K server) MOO!! Re: Wierd memory leak on xeon processors Andy Brummer29-Jul-04 12:27 Andy Brummer 29-Jul-04 12:27  If there is a difference, I'm betting it is only exposing a bug that exists in your code that isn't being worked on your development system. There isn't anything special that you need to do with your code to run on the different processors. I'd run memory validation products on your code, and then check and double check for race conditions. I can imagine the sinking feeling one would have after ordering my book, only to find a laughably ridiculous theory with demented logic once the book arrives - Mark McCutcheon Re: Wierd memory leak on xeon processors Andy Brummer29-Jul-04 12:32 Andy Brummer 29-Jul-04 12:32  Crap, forgot which forum I was in, thought this was C++. The garbage collector tunes itself to the cache size of your processor. I think the first generation is somewhere around the size of your processor's L2 cache. This can change when it collects. Also if the system is only hosting your service, then it is less likely to collect since there isn't as much need to. Have you actually run into memory problems, or are you just worried. You can also add a call to GC.collect just to reassure yourself that there isn't really a problem. Assuming of course that you aren't allocating unmanaged resources that you aren't freeing up.

PJules29-Jul-04 10:58 PJules 29-Jul-04 10:58  Hello, I'm writing an application that needs to add my code to existing client code. I want to avoid parsing the source code so I consider two possibilities: -> Compile it and add the code on MSIL level. -> Create a CodeDOM syntax tree, insert code there, then compile it. I have two questions: 1) Is it somehow possible to load an existing assembly and then insert some MSIL code into it? 2) Can You somehow create a CodeDOM syntax tree from a project that consists of source code files? Do You know any class libs? Namespaces? Websites? I'm happy with any hints! Thanks!

The .NET Framework is a system component and will install into the system root (on drive C: ). Other components of VS.NET will also install into the Common Files folder which is typically found in the Program Files folder, which is typically found on the system drive (drive C: for you). Most files will be installed into the path you specified on drive F:, but not all. Reinstalling VS.NET will help ensure that nothing is broken.   Microsoft MVP, Visual C# My Articles .Net vs Native development argument cheesepirate28-Jul-04 10:49 cheesepirate 28-Jul-04 10:49  We're having a slight argument at work and I'm hoping you can resolve it one way or the other... (The app in question is squarely aimed at corporate environments, so home user type settings aren't relevant.) I'm saying that developing our new product in .Net will be faster and easier - the framework includes things that I'm currently having to implement myself, so I pretty much have double the amount to do compared to using .Net (and I'm running the risk of introducing bugs) The other side of the argument is based around there aren't that many .Net desktop applications and so a .Net app would be harder to market than a Win32 native app. Since this app is driving me a little mad, could someone tell me - are .Net apps harder to market? Do companies prefer to install Native apps over .Net apps? Do sysadmins dislike/have a hard time installing the framework in a corporate environment? Re: .Net vs Native development argument Heath Stewart28-Jul-04 11:34 Heath Stewart 28-Jul-04 11:34  In my personal experience and professional experience as Director of Technology and chief architect at our company, sysadmins dislike doing anything that keeps them from playing solitaire or hiding out in some room playing Xbox. It doesn't matter if they have to install a native app or the .NET Framework + a managed app. The way to market this is the ability of a correctly written .NET application to not require installation. Yes, the .NET Framework and any service packs (.NET 1.0 will have SP3 and .NET 1.1 will have SP1 shortly) are a little bloated, but nothing typical IT solutions can't push out to machines (it is a Windows Installer package when you pass /c /t:path options to the installer executable). The managed application could sit on a share somewhere that all users can use, though IT will also have to push out a code group (if necessary) so that CAS (code access security) is granted the appropriate permissions to run certain code. That, too, is easy. One that app is out there, they never really have to worry about it again. If there's update to be installed, they can simply drop the new assemblies on top the old ones. Through publisher policy assemblies and/or .config assembly settings, even old assemblies can use new assembly versions that they weren't linked against. Assemblies can also be deployed like this over the Internet or an intranet. This is all known as touchless deployment. The IT folk don't have to worry about pushing out updates to an application; when written correctly, the .NET applications will update automatically through Fusion (the assembly bindiner portion of the CLR). .NET 2.0 will make this process even easier (and not require a 24/7 connection to check for updates) with ClickOnce technology. The only major downside is that managed apps can require quite a bit of memory. If you use a lot of types (our flagship app uses almost every assembly of the BCL plus a few other third-party assemblies), it will use quite a bit of memory. A well-written app isn't so bad, though. Another downside (sort of) is that it can be slow to start up since types must be JIT compiled. Once they are compiled to native code, however, the native code is cached and executes about as fast as native calls (stalk walks and the sheer depth of some execution stacks may degrade performance a little more than purely native code). If IT doesn't mind, assemblies can be pre-JIT'd into the GAC using ngen.exe, but that would require some sort of installation. So, depending on how your application is written to be deployed, IT may in fact have more time to sit around and play civ3 or whatever it is they do when not complaining about having to do their jobs and help people. It really works out better for them. I'd recommend reading the topics in the .NET Framework about configuring and deploying .NET Framework applications, as well as security topics as necessary. Truly understanding these topics can help you write an app that makes deployment easy and can help you write an easy-to-update application (like assembly binding redirection so that you don't have to re-deploy every assembly just because you changed one and changed the version - something that should be done).   Microsoft MVP, Visual C# My Articles Re: .Net vs Native development argument softp_vc29-Jul-04 19:12 softp_vc 29-Jul-04 19:12  Hi Heath Thanx for such a valuable information.

I want to use this framework to log in a file, which events occurs in a ASP.NET Application. But i do not really know how i can use this framework and how to start with it. The situation is as follows: i developed a ASP.NET Application for a PDA and now i want to change the code in that way that it would be logged in a file on the PDA what actions a user execute (which events would be execute, which method, at what time,..).

It's an excellent book. Familiarity with the .NET Framework is required. Note that Managed DirectX is not simply a wrapper like many other implementations you may find (including those on this site). It was written from the ground up using the DirectX drivers for optimal performance. More is explained in the book and the Managed DirectX documentation that comes with the DirectX 9.0b SDK.   Microsoft MVP, Visual C# My Articles Type Description at runtime TimMahy25-Jul-04 2:44 TimMahy 25-Jul-04 2:44  Hi, I'm new to this forum but have yet a question : is it possible to get the whole type description of a class at runtime ?

"Network" Mutex? RFID Chris23-Jul-04 12:58 RFID Chris 23-Jul-04 12:58  Hi, I'm looking for a way to implement a network based mutex. For example, if one application on a LAN called Mutex.WaitOne() and got the mutex then all of the other applications using the network mutex would have to wait. Is there anything out there that does this kind of thing? Something simple if possible Thanks! Cheers, Chris Smarten Up Your Assets... www.identecsolutions.com
