Where did you see the namespace reference? Did I pass over it in the specs (though I wouldn't expect to find it there). I've been reading several things about it on MSDN (and now the specs) and have seen much about what to expect (other than the language changes).

VB .NET is also slated to include generics. I don't know how the introduction of generics will affect other languages, such as Eiffel .NET, that already implement generics on .NET 1.x. Presumably they will have to rework their implementation to be compatible?

hii all...
i'm working on an application that preview the current processes on the machine and the state of the process (responding or not responding) and the memory used by the process (something like task manager)
i'm using a listbox to preview the processes
so i have some questions...
1- how can i allow columns??...(one column for the process name and one for the memory used and one for the state and so on)all the information about each process is in the same row the row is divided into columns..
2-i wanna the listbox to disply the changes in the memory used eah 1 sec how can i do it (i tried to redraw the listbox each second but i found it sucks)
3-i used the following code to display the process name and its state :
private static Process[] processes=Process.GetProcesses();
for(int x=0;x

You really should read the class documentation. ListView subitems are definitely explained clearly enough.

Set ListView.View to View.Details. Add columns using the ListView.Columns properties.

You either have to derive from ListView and handle the OCM_NOTIFY messages to have the NM_CUSTOMDRAW notifications, or handle the WM_NOTIFY in the parent of the ListView, handling the specific (and many) NM_CUSTOMDRAW notifications. This requires P/Invoking several Win32 functions from the Platform SDK and redefining a lot of message IDs and structures. This isn't for newbies, but there are lots of tutorials here on CP (which you should always check for first, since that's the whole point of this site).
You can then control which items and subitems are redrawn and when.

for(int x=0;xlistBox1.Items.Add(processes[x].ProcessName.ToUpper().ToString()+"\t\t\t"+(processes[x].Responding ?"Running" :"NotResponding"));
???  There's no different in your output. Check your HTML formatting.
bora3ee wrote:
4- how can i display only current applications not processes???
Applications == processes. Please elaborate. If you want to see current Windows applications / processes, you enumerate the processes and check the Process.MainWindowHandle. If it's IntPtr.Zero, it doesn't have a GUI associated with it (no main Window handle). If the return isn't IntPtr.Zero, it's a Windows application.
In the future, it would also be easy to get help if you post these questions as separate posts. You're more likely to get help with at least some of them and it's easier for potential helpers to follow along and reply when necessary.

Hi
I have VS 2003. However, I do not appear to have the System.Web.Mail namespace. Does anyone know how to get this, or where to download it from? It appears it should be there, as I cant find a download for it on Microsoft.com, yet a lot of their examples use it.
Thank you

By saying that a "namespace is missing", you're implying that you don't have the right assemblies referenced. In a project, you can't just include namespaces in your source files and call it good. The project has to reference the right assemblies that contain those namespaces. So, in your VS.NET project, right-click and select Add Reference. Find the System.Web assembly and add it as an assembly reference.
This is no different than any other API / framework. In C++ you have to bind to a static lib or DLL to call a function in there. In PERL, you have to use the right mod, and in VB - right TLB.

Hi All,
Could anybody point me in the right direction of how to create a class library using C#.NET 2002 standard edition? As it does not have a project template for creating a class library I am finding it difficult to find the right incantation. Any help would be appreciated? (I am assuming this is actually possible....  )
Cheers,
Ewan.

Step 1) Run notepad.
Step 2) Type: class MyLibrary { public void Foo() {} }
Step 3) Save file as "MyLibrary.cs"
Step 4) Compile with: csc /t:library MyLibrary.cs
Presto, you have a class library in MyLibrary.dll, add it as a reference, call it from anywhere, all that good stuff.
(I'm sure someone else will come along and tell you which buttons to push and checkboxes to change.)

Thanks,
Not really answering the question I asked tho: How do I create it in VS.NET 2002. Not notepad? I.e. where is the setting where I tell the IDE that I want the command line compile option /t:library
Thanks,
Ewan.

I know. I'm one of those crotchety old farts who thinks relying on templates and wizards and such weakens the mind.
The "VS.NET IDE issues" forum is five lines down. I don't tease people there.

No problem. Can't say I blame you Am very new to .NET environment having done lots in VC++ 6. Can't say the transition is going well

While I'm with Blake on this one, I will tell you that C# projects actually come in two varieties: ASP.NET and not. For the "not", you can easily change the target type by right-clicking on the project and selecting "Class Library".
Don't forget to the read the documentation and explore a little, otherwise you'll never amount to anything more than a code monkey. Would you spends thousands of $$$ at a university without cracking a book, or take-off in a brand new jet without reading the product instructions and features? Why do so with a framework or IDE (remember, VS.NET is just a development environment).
And exploration is also important - if people didn't explore all 6 billion of us would be stuck around Iran and Iraq were humanity apparently started and we be as dumb as al Qa...er, rocks!

I think you are slightly missing the point. Personally when I approach a problem and find a stumbling block I do the following:
1) Read the documentation.
2) If the answer isn't forthcoming (as it really isn't in this case) (oh and your answer is plain wrong btw for the standard edition) ask someone who likely has far more knowledge than I will every have on the subject.
Result.... almost immediate answer (plus obligatory flaming).
I've coded in c++ for many years and while I am certainly a code monkey at heart I would like to think I do amount to something . Just because I'm trying to expand my knowledge in the form of c# shouldn't mean I have to read the entire MSDN before I'm entitled to ask questions.

Sorry, "right-click on the project, select properties, and select "Class Library". Should be obvious since it's consistent with everything else in Windows, and I was able to find it in the MSDN Library in under a minute by following a natural chain of topics, like ".NET Development"/"Visual Studio .NET"/"Product Documentation"/ etc.
Besides, "coding" does not make a developer. Good research skills are important. And while forums like this are here to help, even exploration of the UI at the very least should've uncovered this. You're right, sometimes the documentation isn't so obvious, but by exploring you certainly learn a lot more. And while some will read the MSDN Library thoroughly, at least exploring the topics covered is better than not - especially the .NET Class Library reference.
So, do you get my point?

My take is that you should do it the "hard way" at least a few times so that you know what's going on under the surface, and then save yourself some time by doing it the easy way.

I agree. Or if you don't try the hard way once, at least try and get some understanding of what the Wizard has done.

1) Create a new Windows Application Project
2) Right-click the project in Solution Explorer
3) Select Properties
4) In General -> Change Output Type from Web Application to Class Library
This will build a DLL. Now you can remove the Form1.cs if desired, and add classes.
Edit: Hmm... didn't see the dozen responses before I replied. Oh well.

Hello!
I have a windows forms application and when I double click it I don't want
the Command window(cmd.exe) show.
How do I do it ?
regards.

If i understood your problem well, you can solve it by:
1. Open Properties Pages of you project
2. Common Properites/General/Output Type set to Windows Application rather than Console Application
Hope this helps

Hi,
i have got some wired problem, for which i can not find the easy answer since i am new to c#. I wrote and application that uses Direct3D to render the mechanism. To drive the mechanism i use complex 6D numerical algorithm that uses System.Math to get solutions. Both graphical and mathematical parts work fine seperately. However when i want to run graphical interface and numerical engine in paralel in a single application i get the following problem(note if i compile two seperate aplications they run fine):
The System.Math starts to behave in a wired way, round function does not work well (i.e. if i try to round to two deciml places, it rounds to 10, or if i try to roung number 999 it rounds it to 1).
I tired to backtrack what causes the problem, and apaprently the probelm comes once create the d3d device is executed:
device = new Device(graphicsSettings.AdapterOrdinal, graphicsSettings.DevType, windowed ? RenderTarget : this , createFlags, presentParams);
To write Direct3D engine, i directly adopted example 'Enhanced Mesh' provided by DirectXSDK.
I think something happens to memory or to recources, but not sure about it. Anyone has any ideas on how to solve this sort of problem?? Anything would be a value to me. IF someone is willing to look at the code files let me know by email to ark@centras.lt, and i will send them to you.
Thanks
