hi,
how do find out what's your 'default com port' in general (e.g. in windows)? Is there anything I don't know? 
bye

Hi,
AFAIK there isn't a "default COM port" at the Windows level.
What may exist is a default port for some app, say a terminal server.
But then the notion only exists within that app, and how it gets selected is depending on that app.

Hi,
I am developing a contact book using C# WPF and a textbox can contain contacts as the user has added from the existing contact book. The textbox showing the selected contacts will looks like: "John; Peter; Tom;".
The user can add new names to the textbox but if he want to edit an existing name that name shall be highlight and not be able to edit the existing name, just like Microsoft Outlook when you send a new email and try to modify a email address added from contact list.
How do I adjust my textbox so it get this behavior?
Example:
The user has added the following contacts to the textbox. "John; Peter; Tom;"
The problem is how do I prohibit the user to modify contact "John" like "John123456789; Peter; Tom;"
If he starts modify contact John the textbox shall contains "123456789; Peter; Tom;" instead.
Regards
Magnus

I'm not sure of any WPF relevance but I would namage the position of the caret in the text (little flashing verticle bar) and depenting on the position and the relationship to the word and ; in the text manage the selected property of the text.

Hello,
Currently I am working on creating a drawing editor.
I am unable to find the function which can draw an arc using a mouse like a line by using the RevesibleLine function.
Thanks in Advance.

I don't think there is one, there's only a method for drawing beziers, which means your user needs to define the individual points. To draw and have a steady arc come out, requires code to create a custom path, I beleive.

How do i get to know the exe path of any random executable in C#?
|
|
|
|
|
By random executable, do you mean the app has to pick one at random with no user input? Use the classes in System.IO (DirectoryInfo, FileInfo for starters) to create a list of EXE files, then pick one at random.

Thank you. I got the answer.it should be something like this
RegistryKey objKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Installer\Assemblies");
string regfilepath = "";
if (objKey != null)
{
foreach (string Keyname in objKey.GetSubKeyNames())
{
if (Keyname.IndexOf("ApplicationName.exe") > 0)
{
regfilepath = Keyname;
break;
}
}
}

I'm working on learning C# using VS2008, and have started a project for various mathematical functions. Everything was working fine, until I tried to separate the file into individual classes. In order to do this, I created a new class (.cs file) for the calculations. Within these classes I needed to reference text boxes found in the Window1() class, so I added this to the Calculations() class:
Window1 w = new Window1();
along with it's twin in the Window1() class:
Calculations c = new Calculations();
Now every time I try to compile and run the program, it returns a System.StackOverflowException error and crashes immediately.
From what I've been able to find courtesy of google, this is because of a redundant loop, but I don't understand where this would be. Debugging the code points to the first class definition above, but as I understand it all that does is make the Calculator() class able to reference the Window1() class.
Thanks for your help!

Where did you add these lines, and why? In the constructor? If yes, then it's no surprise your app crashes - your Calculations instance creates a Window, which creates a Calculations instance, and so on, and then, Wham!
You have to use a better way to pass your form data to Calculations. In fact, creating a new instance of Window1 in Calculations does just that - creates a new instance; you will not be able to access your form's data from that instance.

Okay, I had a whole longer question in here, but I answered it myself (well, I figured it out and once I did, your explanation made sense...I was placing one new Window1() statement in the Calculations class and vide versa rather than individual ones in each method of the given class).
Thanks for the help

Actually to clarify (in case anyone searches this later with the same question, I ended up using ref to pass get the result I needed. Now everything works beautifully.

I hate to say it, but the quality of this forum drops to zero every day at around this time. What country starts to provide a lot of posts at this time ?
You're an idiot. Your question makes no sense, it can't be answered. What do you mean by 'system level' ? Why is google broken where you live ? Why don't you own any books ? What are you asking for, and why ?

Hi all
I hope help me
I want change ipaddress in pocketpc2003, that conneted the activesync
I find registry HKLM\Comm\USB Cable:\Parms\TcpIp, so i modify different ipaddress
but after softreset, dont mofied that ipaddress.. 192.168.55.101
how to change ipaddress 210.xxx.xxx.xxx?
Please reply for me

You want to do this with C# ? I don't think you can do it at all. The ip address is assigned by whatever network you connect to. 192.168.xx.xx means you're on a local network, I believe, and either way, you will get an available address from the specifically available range, you can't just make one up.

That's not a question, it's a statement.
I suggest you go and talk to your teacher. We're not here to do your homework, and if we did it, it would only set you up to fail the next. only slightly less trivial, task that your teacher will give you.
We also prefer people who are not rude, or stupid. You're asking us for help, try to be polite, and try to follow the forum guidelines.

Really not at all sure what you're getting at here.
I think, perhaps, you're talking rubbish. How can a node on a graph be the name of a variable? Doesn't make any sense.

People in fourth grade, are 10 years old. Perhaps it works differently where you are ?
your question, however, makes no sense. Are you doing a programming class ? You'd do better to ask your teacher. He feels he's given you all you need to do the task, and it's valuable for him to know he's failed in this regard, as well as knowing what it is you want to do.
