Why repost the question? Also, what's wrong with you posting on a respectable site with that nickname, be it a phallus or a rooster I don't care. This is unacceptable

Just go to OPs profile page and report as Spammer\Abusive. A whole bunch of members already got the boot for using abusive names. Once a member has been reported 5 times the account is automatically deactivated.

Guys, please relax. The guy is from India. Stop measuring everything with your Western standards. A name is a name. Many names in some languages sound like taboo words in others.

Since this site is an English-language site, I think it's unreasonable to expect a number of people to not find some measure of offense to his ID.

#realJSOP 10-Nov-11 11:50am

The word cock (in English, which is what this site is based on) is considered provocative langauge. If enough people report you for abuse, the account will be removed. Change your user ID, or take the chance that your account will be deleted. Your call, sparky.

Repost, fair enough. Nickname? Don't be so sensitive, cocksure I believe is more like cocky or arrogant and is fine as a name.

Just switch your username to 'Rooster77,' and repeat to yourself "koy baht nahin" until you feel at peace.

Namaste, Bill

Would give you a 5 for this if I could Bill
:D

All you "internet-proven" guys cry because of a bad nickname while there is a CODE-PROBLEM? - makes me smile. (but its no provocative or abusive smile!)

Probably mistaking codeproject with a social network!

Anyway, i'm not going to take it personal with your nick name and the like but please do take advise.
Below is the code i would use to convert an image to text, well basically to it's base64 representation, that's if i got your question right:

C#

try
{
    
    System.Drawing.Image img = System.Drawing.Image.FromFile( "img path here" );
    ImageFormat format = ImageFormat.Png;
    MemoryStream memory = new MemoryStream();
    img.Save( memory, format );
    string base64 = Convert.ToBase64String( memory.ToArray() );
    memory.Close();
    File.WriteAllText( "img.txt", base64 );
    Console.WriteLine( "data written to the chosen text file" );
}
catch ( Exception ex )
{
    Console.WriteLine( ex );
}

This works for me.
Happy coding,
Morgs
