However, is there any rules to divide the code? By function, by class or by other factors? Thanks Re: What are the good practises to write an complicate application? Daniel Turini3-Dec-04 19:16 Daniel Turini 3-Dec-04 19:16  ting668 wrote: However, is there any rules to divide the code? Yes: 1. When something is reused, it goes to a DLL. 2. When something needs to hide classes, data and references to other DLLs, it goes to a DLL. E.g., Data Access Layers - we have a rule where no project but the DAL should use a SqlConnection or an OracleConnection. When classes or data need to be hidden, but public to an assembly, we use the 'internal' keywork and put it on a DLL. 3. When the project is mature (i.e., we're on the optimization phase) and something is slow to load, and will not be used on the application startup, it goes to a DLL. Yes, even I am blogging now! Re: What are the good practises to write an complicate application? Anonymous3-Dec-04 19:18 Anonymous 3-Dec-04 19:18  you only use dlls if you wanna reuse that specific code and share it among more than one program and the rules varry depending on how you want the dll to be used you may for instance want to make some sort of graphics dll with might include several classes or you may just want a single class in your dll such as a simple custom control that you share between a few programs. they are also usefull if you want to update only specific portions of your software without updating the entire release. sometimes it may just be simpler to contain all your code within a single .exe file as it makes installtion easier becuase dlls need to be registered with the os and the more seperate compenents your program has to deal with the greater potential for error/corruption as well as problems with updating a dll and breaking the code in your exe known as "DLL HELL". i hope this helps Re: What are the good practises to write an complicate application?

I tried an explicit cast, but it didn't like that neither. help please? thanks all! "There are 10 types of people in this world; Those that know binary and those that do not." Re: string to int Charlie Williams3-Dec-04 18:12 Charlie Williams 3-Dec-04 18:12  Int32 has a Parse method that takes a string parameter or you can use the ToInt32 method of the System.Convert class. Both will throw a FormatException if the string cannot be parsed (including empty strings), or an OverflowException if the value is < Int32.MinValue or > Int32.MaxValue. Int32.Parse will throw an ArgumentNullException if a null value is passed, whereas Convert.ToInt32 will return 0. Charlie if(!curlies){ return; } Re: string to int John L.

Daniel Turini3-Dec-04 19:11 Daniel Turini 3-Dec-04 19:11  Theoretically, it could be, as ASM code would be fixed for a single machine and use profile, while .NET IL code could auto-adjust to conditions on machine that would be detected on application startup. In practice, .NET IL code is several times slower (tipically 5~100 times) than hand-made ASM code. Yes, even I am blogging now! Re: help...

Robert Rohde4-Dec-04 8:38 Robert Rohde 4-Dec-04 8:38  The standard arguments for that are, that the JIT could build asm code specific to the hardware the program is running on, like processor architecture, cache size and even transfer some calculations to the graphic card etc... But I also think this will never happen, because the JIT would have to be 100x more intelligent than the best c compilers of today. Re: help... Alex Korchemniy3-Dec-04 21:07 Alex Korchemniy 3-Dec-04 21:07  The two are very different actually. It wouldn't be fair to compare. Do a little research. If i had some time i would explain.

All in one single file. I need everything in one single file for now. Later I will may break it up into smaller header files if possible but I want it in one file for now. I need a way to actually break the page where you type the code in the IDE of C#. It should look like two or more pages somewhat like typing several pages in Word Perfect assuming that it is possible to do it in C# version MDE2002. I am not even sure if it will allow you to continue typing if you could break the code area into several pages but I would like to know for sure. Somewhere around 40,000 or 50,000 lines of code C# prevents you from typing anymore and I need many many more, 1000's of lines of code to complete the functions and classes that I need. It is not an OS, but a very very complex calculus based mathematical piece of software with thousands of methods seperate from each other such that it requires it. An OS probably has millions of lines of code. I have seen GUI EXE files that are several megs in size so it is not uncommon for huge file sizes with tens of thousands of lines of code. Mine only has tens of thousands. So, is there anybody with an answer for the following... ... I have 3 questions for the page break experts out... ...

Are you printing your code? No matter what one may argue, a long method or a long class is a bad practice: it can always be shorter. Actually, by making it shorter, often you'll find lots of bugs in it. Don't do a "page break", whatever you meant by it: reduce the size of your code. Yes, even I am blogging now! Re: Very Very Long Complex C# Programs Anonymous3-Dec-04 19:22 Anonymous 3-Dec-04 19:22  yeah your best option would be seperate your code into individual files thats the best programing practice you can follow. seperate your program in a logical manner not only is it easier on the compiler but its also easier to navigate and use overall as far as i know there is no way to insert a page break thats a word processor thing Re: Very Very Long Complex C# Programs leppie3-Dec-04 22:18 leppie 3-Dec-04 22:18  My "IDE" can handle roughly 600 000 lines but thats purely a GDI+ limitation, and I have been too lazy to work around it. My suggestion is to generate the file, but make it abstract/virtual, compile to DLL, then load that assembly in your IDE, and inherit from the class. top secret Download xacc-ide 0.0.3 now!

Re: Very Very Long Complex C# Programs demasoni.com4-Dec-04 19:34 demasoni.com 4-Dec-04 19:34  Insanity and genius are merely a mirror image of each other. I have written many projects that easily run into the tens of thousands of lines of code. Most who do that very easily are developing very complex programs or even creating new technologies, like I am, that are not even on the market. I would feel that most of us who are creating new technologies are in the genius/insanity class. We should all be experts at cutting the code to an absolute minimum. A lot of the times you are limited by the compiler and the computer. IMO todays PC computers are "extremely" pathetic for processor power and speed. I have very easily pushed the envolope on a 2.4 ghz pentium and a gig of 800 mhz RIMS for the exe file. We need a supercomputer in a laptop instead of that that cheesy plastic box of copper and silicon they call a computer. Even my desktop with the hot ram, cpu, and SCSI drives is what I consider a flibber. JMO, anyway.
