It's a diagram showing the transmission of data between a client and server via a router. What is it that you do not understand?

Fine, what problems are you facing?

The reason it's jagged is because you didn't use pre tags.

I want to change text file extension to custom extention..... the following code successfully run.But, doesn't change the extension. In the following code, If I use
string myfile= Path.ChangeExtension(fileName,"ndbm"); It return same thing.....Please help me..
private void changeButton_Click(object sender, EventArgs e)
{
string fileName = @"DataBase\" + exFileNameTextBox.Text + ".txt";
if (File.Exists(fileName))
{
string myfile= Path.ChangeExtension(fileName,".ndbm");
MessageBox.Show("Successfully Changed");
}
else { MessageBox.Show("File Not Exists"); }
}

Read the intellisense on the method "Changes the extension of the path string". Which mean it has changed the extension of the filename string, exactly as it says.
You need to read and rewrite the content of the file to the new file name.

As Mycroft said, it changes the extension of the path string.
To change the extension of the file, try this:
if (File.Exists(fileName))
{
string myfile= Path.ChangeExtension(fileName,".ndbm");
File.Move(fileName, myfile);
MessageBox.Show("Successfully Changed");
}
Hope this helps.

you are doing it wrong you cannot do this in a string it is done only in the string..........you have to change the command such that it is not inside a variable.........maybe us this in the from load event
Path.ChangeExtension(fileName,"ndbm");
i cannot assure you that this will definitely work i only give a suggestion............although you do need to change the code such that it does not happen inside a variable...........

A very bad answer, it does not address the OPs problem and is barely understandable.

If you don't know what you are talking about then do not participate, the OP may know even less than you do and think you have given a valid solution.

I have to agree with Mycroft - if you aren't sure if something will work then test it before you offer it to the OP as a solution. That way, you either post a working solution, or you learn something. Then everybody involved gains.
Just posting stuff because "it might work" isn't what this site is about, and make it look like you just want reputation points for free. That isn't a good idea!

I am really sorry for the mistake.............I will try my best not to do this again.......actually i am a beginner in c# and on codeproject so i did not know I am really sorry for the mistake............I was just trying fro help not doing this for points although I do admit my mistake and hope not to do it agian  .......

No need to apologise - just think about it from the original questioner asker's point of view: is what you are telling him useful? Or pretty much useless? If it's the latter (and yours was) then either don't post it, or try it first so you can be sure you are posting correct info.
(It's a good idea to do the latter anyway - it's far too easy to mistype something and confuse the OP even more!)
Welcome aboard! If you are a beginner in C#, it's not a bad idea to try and work out the answers you would give, but not necessarily post them. Then check the answers that were posted against what you would have written. It's surprising how much you can learn that way, and how much it improves your code as well as the question setters! It's how I started here - then when you get some confidence, post answers. Worked for me

That was obvious and the reason you were not lambasted, but you must remember that a wrong/untested answer here can misdirect someone with even less knowledge than you.

Don't let that stop you if you are sure you know the answer then go right ahead and help.

hi
i need to component that similar listview in c#, user information stored on it can be changed and re-use that information, But I would not put it in gridview because I do not need to database.
please help
|
|

|

Next time clean up your original post, don't post twice.
There is no correlation between gridview and database, the gridview does not care where the collection comes from.
What is the UI technology you are using, I suspect ASP!

thanks
Do without use of databaseو can be used in the gridview?
How can this be done?
|
|

|

As you did not indicate which UI you are using it is a little difficult. I suggest you work through some tutorials on the tech you are attempting to work with.

Hi All,
I am _occasionally_ (inconsistently) getting "Attempt to write to read only database" problems with System.Data.SQLite. Googling this issue brings up lots of pages talking about file/folder permission issues (especially with web servers).
I have a Windows Forms App and no web server is involved. Additionally, this problem happens inconsistently (like with every 20 Inserts) and I've got my database in %APPDATA%\MyApp folder (where %APPDATA% is set to the ...AppData\Roaming folder on my data drive). I have no reason to suspect a file/folder permissions problem.
I added a delay to each Insert and I observe that the number of, and likelihood of getting a "Attempt to write..." error is directly related to the length of the delay - a delay of 1 second after each Insert seems to *almost* completely relieve the problem.
Do I have a misconfiguration problem? Searching the net shows lots of positive comments for the stability and correctness of System.Data.SQLite and no solutions suggested except for file permissions config, but my system behaves like SQLite is tripping over itself. There are no other file operations (outside of the OS activity) happening at the same time. I'm out of ideas - help!
I'm using C# vs2008 (I think it's .net 3.5). It was a Win7 box but now it's a Win8 box (no difference for this issue).

A long shot; but do you have any indexes defined in there that it might try to update[^]?

Thx for the reply. No, I did not explicitly add any indexes (indices?). I just did a "CREATE TABLE..." and followed it up with Inserts and Selects. The Selects work fine. The Inserts don't.
I'll take a look with that ANALYSE command that you reference.

|
|
|

OK I ran the ANALYZE statement but it doesn't show anything. Any other ideas?
