 Hi all,
I am very new to .net programming and doing alot of reading but am getting a bit list with some of the terminologies. Could somebody explain the building blocks of .net programming eg: objects, classes, methods etc etc.
All responses will be gratefully accepted.

Hi Chinna,
Thankyou very much for answering my post. I am just starting to teach myself .NET programming. I have taught myself basic programming, but wish to channel all my studies in to .NET. I am at the very beginning and was hoping that somebody would be able to give me an application diagram or something similar which would show me the concepts of object oriented programming eg: how classes, objects, methods, functions, enumerations, interfaces etc etc all fit in together.
Hopefully this is making sense. As I mentioned I am right at the beginning of my studies but this is something that I really want to devote alot of time to, and I will keep on reading but am hoping somebody can give a clear picture of how an application all fits together.
Much appreciated.
Craig.

My suggestion: Don't start off trying to learn the .NET hierachy. It's huge.
Learn in small chunks.
Start by learning from a good book on OO techniques. I'm afraid all my basic reference works are out of date, but I'm sure a search in Amazon or Google will help. Look for books that have several *independent* good reviews.
Learn the basic principles of encapsulation and data hiding, inheritance and abstraction. Understand what is meant by "Design by Contract".
Don't go into multiple inheritance - it's a minefield, and not supported in .NET anyway.
Learn about the failings of OO too: where it doesn't work as where it does. For example, that mututally dependent objects can cause unwanted side effects. It's harder to find info about where/why OO doesn't work because it's not "cool", but it is useful to know, all the same.
Although not all directly relevant, books like "The Mythical Man Month", "extreme .NET" (Roodyn), "Microsoft Secrets", and "Classical and Object Oriented Software Engineering" (Scach) might be of interest.
HTH,

Hi
before you are going through the .NET syntax and other .NET stuff. You should understand OOPs concept. There are lot of website describe the OOPs in better manner.
Once you understand the OOPs then you will get answers for your maximum number of question.
Thanks

I am new to Biztalk Server and am having difficulty. I was able to do a project.Build and deployment were successful. Where I run in to difficulty is when testing When I drop the file in the in File folder - it leaves immediatley, but never appears in the out folder. Please provide me with some troubleshooting tips. I have checked the ports, all appear ok and are up and running. When I look at the BizTalkmgtDatabase I see entries in the receive and send tables, but the message never appears. Please provide help ASAP.

Hi ,
Can any one please let me know how can i use the vc++ code in c# using the concept of Managed and Unmanaged code?
Bcoz i dot have any idea about the interface so please suggest me about how i can go ahead.
Thanks

Yes, if your new to this i would start simple. For my final project at uni i had to wrap an old C++ header file to .net. It was very tricky, but not imposible!
First have a google at wrapping C++ into .net, and get round the concept of IJW (it just works) that try a basic C++ concole app first in MC++ to wrap it into .net!
your first example wants to be simple, then move on to pinning parameters, this is a bit complex.
good luck

I heard on the MS parnetship sites that the VS2005 service pack 1 was shipping next week. But, the public potion of MS says Q3.
Does anyone know the truth?
I heard it has edit and continue for c#, so I can't wait.

1 line of code equals many bugs. So don't write any!!

What do you mean with "Edit and Continue"? I assumed it just meant you could change the code from the debugger and continue execution of the modified code directly. But since this is already available for C# in VS2005 without any service pack, you must be referring to something else?
|
|
|
|
|
It doesn't work for me. Is there a setting?
It barks at me if I try and continue. On the partnership sites it says ts not available till q03.

..its defintely in. I use it all the time. Had an idea that the service pack isn't out for quite a while yet, which is a pity as there's quite a few issues which need addressing.
Tools->Options, Debugging->Edit and Continue->Enable Edit and Continue.

I don't have the Debugging section in Tools->Options.
Although I have the VB setup because I like the VB shortcuts better. Is that an Issue?

As far as I'm aware it's due in q3. However, VS 2003 SP1 should be due any time now. Maybe that's what the confusion is?

We have used one listbox in windows form and we bind it with datasource from database.
Listbox allows multiple selected.
How can we retrive value of selected items from the list box??
we tried following thing
for(int i=0;i
|
|
|
|
|
What do you think is the selected value?
You filled the list with a DataView (which is a set of DataRowViews), so SelectedItems[n] returns the selected DataRowView.
I hope you have already tried that:
MessageBox.Show( ((DataRowView)lstEducation.SelectedItems[i])[0].ToString() )

Along with the first post you can also set the DisplayMember and ValueMemeber to the column names you would like to display and key off of.

i made a webform in asp.net and i want to print that web form design by clicking the button in the webfrom.anybody know how can i do it?
thank you so much
|
|
|
|

Sure you can print it!  Attach to button this client script "window.print()" it's all you need to do. Also you can put two functions on your page
function window.onbeforeprint()
{
//Make you changes before printing, like
//hiding unnecessary while printing elements
}
and
function window.onafterprint()
{
//Restore previous state after printing
}
|

IS it for visual basic ,asp.net webform?
|
|
|
|
|
No, it's Javascript. If you would use ASP.NET to print anything, it would be printed on a printer connected to the server.

I am using Asyncallback in .net CF development. I added the callback in a button_click event, but as I run the program, it is fine to deploy the program, but as I click the button, error occured. The message is 'An unhandled exception of type 'System.NotSupportedException' occurred in System.Windows.Forms.dll', and it stopped at 'application.run(new form())' I used the begininvoke to start the callback, and endinvoke to get the result. Thanks for your help.
