Good find.

Thanks.

Solution 4

A bit vague, I'll attempt a guess:

Read the data into a buffer and create a MemoryStream

byte[] buffer; // read data to this. omitted.
MemoryStream stream = new MemoryStream(buffer);

Create a Bitmap from the stream

Bitmap bitmap = new Bitmap(stream);

In the form's Paint event handler, draw the image thus:

C#

private void Form1_Paint(object sender, PaintEventArgs e)
{
    e.Graphics.DrawImage(bitmap, x, y);
}

x and y are the coordinates of the place where you draw the image.
(look up each method in MSDN for details)

Indivara, this is a good clarification to my rather short answer - my 5.
I decided not to detail if memory stream should be used or not, because I was confused by OP mentioning of "streambytes". I though OP already might have a stream, in this case re-writing a stream to read from memory would be redundant. How do you think, what it was?

Thanks Sergey... you seem to be voting for most of my answers :)

Apparently I was completely off, the question's been updated. You were right, we should ignore this type of question

Sergey Alexandrovich Kryukov 31-Jan-11 20:12pm

I do vote but not specifically for you answers. And I don't touch something I don't know well enough, like SQL.

Indivara 1-Feb-11 1:40am

That came out backwards. I mean almost all my votes are from you...

Sergey Alexandrovich Kryukov 1-Feb-11 2:59am

No, this is in historical order...

Indivara 1-Feb-11 3:10am

No no, you still misunderstand. What I said, the meaning was reversed. Not "you have voted for my answers only", but "most of my answers get votes from you only" :)

Sergey Alexandrovich Kryukov 1-Feb-11 3:29am

I do understand the difference, thank you. My reply is still valid. I just comment on questions I find interesting if I understand the matter well enough.

Indivara 1-Feb-11 3:33am

OK sorry... anyway it is reassuring to have them, thanks!

Sergey Alexandrovich Kryukov 1-Feb-11 3:41am

No sorry at all. This is also my pleasure.
And I also love to learn something good, in general, or to appreciate wise though.
Thank you.

And my idea of ignoring was about some other question, I think, where even more of a guess was done. I suggested we should demand reporting certain things; Framework/language version, often an exception dump (but probably many do not know how to retrieve such info), etc. Guesswork is only a waste of time and a source of trouble.

Indivara 1-Feb-11 3:11am

Yep, I couldn't remember where that was. I agree, it is a waste of time...

Sergey Alexandrovich Kryukov 1-Feb-11 3:36am

May be we could formulate requirements to Questions the way they could be re-used.
I tried to post the Suggestion, Chris Maunder replied that the stupidity is hard to predict. Regardless, I still think some requirements would help, because I repeat them too many times. Not posting a Question along is ignored.

I recently asked not to put the Answer at the last sentence of my Answer (use "Improve Answer", "Add Comment") -- received follow-up question posted as Answer in next 5 minutes... :-)

But there already is the FAQ, and nobody seems to read that (or maybe, those who read it don't ask questions or, don't need to because they can find out anyway)

Sergey Alexandrovich Kryukov 1-Feb-11 4:11am

That's why I say, may be something better will work. Let's say: we see substandard Question, and instead of asking particular questions, reply to the patient: you did not provide sufficient info -- read _this_ first. Hah?

Indivara 1-Feb-11 4:58am

I sent you a link - no idea how to let an anonymous individual edit it. (Share another document with me and I'll add your ID)

Sergey Alexandrovich Kryukov 10-Feb-11 13:55pm

Indivara, as I say I din't receive your link even though I received e-mail notifications about this link. What it was?
Thank you.

Assuming the question is about System.Drawing, you need to read your image from stream, see 3 overloaded methods System.Drawing.Image.FromStream. You can draw the image in Paint event:

C#

MyControl.Paint += delegate(object sender, PaintEventArgs eventArgs) {
    //...
    System.Drawing.Point imageOrigin = //...
    //...
    eventArgs.Graphics.DrawImage(myImage, imageOrigin);
} //Paint

In WPF, you don't need to render like this, you should use similar but quite different API for images... do you need help on WPF? (You should always indicate in question what UI library you want to use: System.Windows.Forms, WPF, ASP.NET or something else (Qt, etc.))

That's always the best advice for this kind of questions.

Sergey Alexandrovich Kryukov 31-Jan-11 16:14pm

That's right (my 5), I should have mentioned array of bytes as a more universal presentation to expect.
