Well, I haven't tried anything, as I have no clue. I looked at a bunch of examples of writing to text files, but none of them did what I am trying to do. I have certainly created text files from data before, but it has always just been single-column data written to a text file record.

So, if my listview rows look like:

Frankfurters REG_SZ C:\Windows\Blah\Blah
Hamburgers REG_SZ D:\SomewhereOverTheRainbow

then I want to take the data from the multiple columns on each row and create a text file record that looks like what is displayed above (for wach row) - I later want to be able to properly retrieve and separate the text file records into multiple columns for downstream manipulation.

Rather than just a plain text file, I would suggest either XML or CSV for this.

Thanks for the quick reply. I am a transplanted mainframer. Can you give me an example to write such a file? Either one is fine by me, as long as it is a commonly accessible format on remote machines.

You are opening a stream and writing from the start. You need to open the stream and write at the end.

You might find this article in MSDN on How to Open and Append to a ... file[^] useful.

You will need to get the FileStream yourself and make sure the stream is at the end of the file. You can then pass that to the StreamWriter, and it will add text on, rather than overwriting it.

Pretty simple:

//This should open the file (if it exists) and then seek to the end if the file.
//You should check out the other options for FileMode as well
FileStream fs = new FileStream(path + ":\\Batch_BDD_PROD\\nb\\TXT.txt", FileMode.Append);
StreamWriter monStreamWriter = new StreamWriter(fs);

try
{
monStreamWriter.WriteLine("Ma toute2 première ligne ..."); 
}
finally
{
monStreamWriter.Close();
}

Drag & Drop problem

I have problem in C# when I want to drop text on my textbox. If I drag tet form notepad it work ok, but if that text is html link I end up with link to the page, not link caption, withc I want.

I use thise
string tmp = (string)e.Data.GetData(DataFormats.Text);

How can I know what type of object is over control, if it is link from browser what should I do. I saw html type and I could parse it but my problem is how to know that object is link, and not a plain text.

Did I make myself clear?

Hi,

not sure I understand you correctly. You are dragging some text, which might be a URL? and if so, you want the content of that page rather than its URL?

If that is what you want, then you have to write code to that effect. Check the text starts with "http" and when it does, use WebRequest/WebResponse to get the content. If it fails, drop the URL; if it succeeds, drop the content (which could well be a lot of HTML mumbo jumbo, or an image, or just almost anything).

Smile | :)

Http Header code (example 200,404,..)

I want to determine HTTP header code of a URL by C# code. How could I get that?

I use the following code :

<br />
public Dictionary<string, string> GetHTTPResponseHeaders(string Url)<br />
        {<br />
            Dictionary<string, string> HeaderList = new Dictionary<string, string>();<br />
<br />
            WebRequest WebRequestObject = HttpWebRequest.Create(Url);<br />
            WebResponse ResponseObject = WebRequestObject.GetResponse();<br />
<br />
            foreach (string HeaderKey in ResponseObject.Headers)<br />
            {<br />
                HeaderList.Add(HeaderKey, ResponseObject.Headers[HeaderKey]);<br />
                textBox1.Text += HeaderKey + ": " + ResponseObject.Headers[HeaderKey]+"      " ;<br />
            }<br />
            ResponseObject.Close();<br />
<br />
            return HeaderList;<br />
}<br />

but It does not contain of HTTP header Code!

This should be cast to an HttpWebResponse if the Url you are passing uses HTTP or HTPS as the protocol.

HttpWebResponse responseObject = (HttpWebResponse)WebRequestObject.GetResponse();

You will then find a StatusCode property which contains the detail you want.

Read the documentation!! here[^]

StatusCode is an enumeration, 'OK' = 200. Just write yourself a method to return a string of the numbers based on the value of StatusCode.
