Just for give you hope. I think everthing is posible in programming. But your work looks a very heavy task. Most mobiles use rs232 ports to comunicate with the pc even those usb mobiles (they use a usb to com converter chip, some of them anyway) so you could start playing with com ports. It's not too much help.

I was just trying to use some of the System.Net classes and im finding out that some of them are obsolete, but i've seen people all around still using them, and i havent found another class to use instead. What am i supposed to do?

Here[^] is a link to MSDN's available download of deprecated API members. Most of them provide alternate suggestions.
Deprecated, of course, does not mean deleted. It's a way to get people started on their migration without leaving them holding the bag. Of course, ignoring the deprecation is done at one's own risk.
Good luck.
The most exciting phrase to hear in science, the one that heralds the most discoveries, is not 'Eureka!' ('I found it!') but 'That's funny...’

I appreciate the link to the ".NET Framework 2.0 Beta 2 Obsolete APIs", it does say which classes and methods are obsolete, and it says also what to use instead, but what if i dont have .NET Fx 2.0, how can my code work in both versions, 1.x and 2.0.

Had anybody found that DataColumn.Expression sometime is valid and sometime is invalid?
If the DataTable which have a column define DataColumn.Expression binding a DataGrid which has a GridTableStyle, when your edit the grid and change the cloumn value which relation with the column has set 'Expression', the relation column MUST NOT calculate and display a new value.
If I use DataTable.New to create a new DataRow and set value to the columns(not needn't set value to the column has set 'Expression'), and then use DataTable.Row.Add to add a new row, it sometimes can calculate and display a new value. But if I change the column's name and accordingly modify Expression's value, sometimes you surprise to found that it can not work, why?

Haha..., I got the answer myself.
If you write the sentence
this.dataColumn.Expression="Col1 * Col2";
after
((System.ComponentModel.ISupportInitialize)(this.dataTable)).EndInit();
then it will work right.
But if the code generate by IDE wizzard, it gererate the dataColumn code at the front part, and the sentence '(...).EndInit()' is generate at //Formxx part which must be generated at the end of mothed InitializeComponent(), so, the 'Expression' can not work.
As the said, if you want to use 'DataCloumn.Express' property, the good way is written the code yourself after InitializeComponent().

I'm having difficulty understanding how to explain the following code. Please help...we have to dissect it and explain the operation of the code once it is executed. In advance thank you...
using System; // Rethrowing exceptions:
class MyClass
{
public static void Main()
{
MyClass x = new MyClass();
try
{
string s = null;
x.MyFn(s);
}
catch (Exception e)
{
Console.WriteLine("{0} Exception caught.", e);
}
}
public void MyFn(string s)
{
if (s == null)
throw(new ArgumentNullException());
}
}

What's wrong with this code?
It workes well. When the program call the MyFn(s) and execute the throw state then it throw out a exception, in the Main() which make the MyFn(s) call most nearly, the try block catch the exception and goes to deal the exception code 'Console.WriteLine(...)'.

You missed the point of his question. He was not wondering why the code would NOT work, he is wondering why the code DOES work.
My guess would be he's taking a .NET class and this is an exersize for the student to explain rethrowing expetions. However, the code in question does not REthrow and exception, it merely throws one and catches it.
I should resist the temptation to help you cheat, but here goes anyway.
The "try" is saying "run the code between the next two braces, and if an exception is thrown during any of it, then "catch" that exception and run the code in the catch block. If no exception occurs, don't run any of the code in the catch block.
Your function MyFn() throws an execption if the parms are null, and the catch block in Main will catch it and run the code in the catch block.

Whenever a child form is generated, a set of control box (minimize, maximize, and close buttons) for the child form appears in its parent even though a control box of the child form itself is disabled. Is there any way to disable some or all buttons?

Hi folks,
I want to print out data to the screen in two aligned columns. For example the first column is from 0-20 and the second is from 30-50.
It's simple but I don't know how to implement that  .
Any idea?
Thanks,
Tommy.

With my understanding of your requirement, I would suggest take the Datagrid and the specify the length of two column. I would also suggest that use percentage way to represent the size.

I wrote a small C# .NET program that has one form and one class (written by my boss) that opens a socket on a remote server. The socket class is able to open the socket and then the class fires an event back to the form when it does. This event calls a function within the Form1.cs class which makes an attempt to post output to a textbox on the form. It goes through the first few lines of code in Form1.Connect(...) but when it gets to the line mytextbox.AppendText("...") is jumps to a random line in the code of the socket class. For the life of me, I can't seem to get around this. I think it has something to do with the thread on which the event is executed and the thread that handles painting/appending text/etc. to the form. Any suggestions would be GREATLY appreciated.

Take a look at this article[^] on how to call UI thread objects from different threads.
This could be the reason for your problems.

Hello,
I'm trying to copy a treenode and all it's child nodes to the Clipboard.
So far all I can get to happen is to send the selected node text to the clipboard.
I was thinking that setting the clipboard data to whatever dataobject you sent in would send the entire thing over, but apparently not.
So for example I have this TreeNode:
+TheTreeNode
|--Child1
|+--Child2
|--Child2.1
|--Child2.2
|--Child3
What I want to do is click on TheTreeNode and copy that to the Clipboard.
When I paste somewhere, I 'd like to get the exact tree structure, or close to it as text.
I was thinking converting the node to xml then copying that to the clipboard, that seems like a long way around.
I'd appreciate any ideas or directions I could investigate.
Thanks, in advance!

Hey guys,
This is the Ultimatum of a thread i post yesterday and is gone back in pages anyway. This was about .NET transparent code, and at first thought realised that .NET was not suitable for commercial software.
I JUST WANT YOU TO READ MY NEW POINT OF VIEW!!!
I have to tell you, i have been thinking and commercial software means you buy a software and that software is yours, 100% yours and that should mean that source code should be included to do whatever you want with it cause now it's your property.
But this doesn't apply to MS products, i haven't seen a bit of Windows src included rather than API methods calls in my apps. Anyway it's an example.
If we analyse it from the moral & etical point of view, it's right to include sources to commercial software. But users should be responsible from what they do with it. MS .NET provides an easy way of deployment for the people who wants to play with the sources.
So i'm glad the way .NET works and if any of you are going to develop a commercial app then copyright it and apply all the legal stuff to it. So if you find your software cracked or ilegally modified you can theorically apply legal penalties to the cracker or whatever you wan't to call the victim.
I didn't know that the fast and "secure" C++ native code could be disassembled and watch code the same way it was written, so any programming language can be disassembled, that means all the languages are at the same level but something i'm sure about is .NET rocks and is the way to go man!
Best regards,
Heinz

No, it's not. You bought a license to USE the software, not own it. The code is NOT yours. In most EULA's, you're expressly forbidden to reverse engineer the executable code to come up with anything resembling the source code.

Hi Dave,
I know it's not (i haven't a single commercial software that includes src and all EULA's as you said forbidden reverse engineer). But is my way to see it, opinions are allowed of course.
Thanx for opinion.

If you are making a customized software for a particular customer, it is alright to give him the source code. But, when you are launching it as a generalized product to a large number of people, disclosing source code may not be desirable and is not necessary as a legal requirement. Even as per the moral requirements, it is not necessary because what will a common or lay customer do with your source code? He is simply a user of the product and that too one of a large number of users. But, your rivals will definitely benefit. Of course, if your target group is the open-source, you may very well disclose your source code.
So, unless it is a customized software made for a particular customer only, a commercial application need not disclose source code. In today's cut-throat competition, it may not be advisable. So, disclosing source code of a commercial application may be injurous to your financial health.

In some cases, even MS is also disclosing its source code, e.g., in MFC classes. Even for the .NET classes, you can see the code of the relevant dll files of MS, using the same ILDASM as for your code.

Legal processes are lengthy and costly. You may not be able to enforce your rights. Moreover, in an international scenario, enforcing legal copyrights becomes very difficult or almost impossible. Even a big corporation like MS has to live with a high level of piracy as the legal processes are not always productive or feasible.

Thanx for your comments, i agree in all you said. I'm developing a commercial app for a huge crowd, and i have got competition and people who hates me so i asume that there will be a cracked version or something that smells around the net only to take me down. But it's part of the normal process, as you said MS has to deal with that i'll have to deal with it too but it's going to hurt more.
Thanx for your help and lets face the reality.
