Go to these links 4 help... these links will tell u how to create bitmap

You need to scale this large problem down into several smaller problems. I would be inclined to first get the actual communication working at a very basic level before anything else. The calling machine(s) should be able to send multiple requests to the remote machine without any of them being lost. The remote machine could simply write "Received request from xxx." to a file of some sort.

Then I would have the remote machine "answer" those requests by being able to take a snapshot of its desktop. Simply send a 0 or 1 back to the calling machine to indicate success or failure. Have the calling machine display this acknowledgment.

I think dis will work.... Please provide me a method how to send on sockets... and retrieve it.. we`ll copy it into buffer for sure..

I'm not sure if this is the proper section, but....

I'm working on a project right now where i need PNG support for texturing our models and i heard from many sources that libpng was the way to go for it. However, I don't have much experience with libraries and have never installed one and am completely lost right now.

I have read through most of the .txt files included with it and still don't know what to do, I've tried building the zlib and libpng projects but they tell me there are .h files missing that need to be there.

I have no idea what a makefile is which another part tells me I can try (I tried running some of the files in the scripts folder where the makefiles are located, but they just crash).

I downloaded the .zip file for it from : http://www.libpng.org/pub/png/libpng.html

Any help would be appreciated.

make sure your IDE or your project points to the include directory of any add-on library. We use both libpng, and zlib and others. When you get into the habit of using 3rd party libraries you will get into the habit of adding to your include list.

I prefer adding the libraries to the project rather than the IDE since it gets ported with the project rather than having to set up everything all over again each computer.

hi..plz i need to know a presice definition about Dihedral angel or reference's name talks about that angel regards
miss maria

Even spelling it 'angel' instead of 'angle', google gave me the definition in seconds.

Thanx alot for that website..im Ph.D student i was need info. about that angel..! sorry angle Smile | :)

...angel and angle share something is that: both, they have wings Smile | :)

.. thanx again .... Petrovna

I'm not sure you should be openly admitting this.

hi..U can b sure that im admitted what u wrote openly Smile | :)

..
if u read my question(of subject:help) u'll discover that im simple person..my question was very simple compared to my study..but im always like asking people around me..& im glad 2 give answer about any question asked to me Smile | :)

..
second sentence its very nice. Petrovna

helloo brothers..my program like paint (drawing lines,ellipse,...) the problem that i cant zooooming ..so plz what should i do...
note : iam using v.s (2003)..

Regards;

Try using the Scaling Transformation on the Graphics object. You can reference the method like this: g.ScaleTransform(2.0f,3.0f)

Cheers!

the error...>>(cannot implicity convert type 'System.IO.StreamWritet'to 'System.IO.Stream'.

Seriously, stop this project and go pickup a book on beginning C#. You've got some serious "C# and .NET Framework 101" issues to contend with. Just getting something as simple as a StreamWriter to work is giving to fits. Actually doing some drawing is about 10 times more difficult.

Besides, how are you going to save you're image? Are you really going to try to write binary data to a text file??

Dave Kreskowiak :how are you going to save you're image? Are you really going to try to write binary data to a text file??..yes .
ok look bro i have changed my saving code and used StreamWriter but its doesnt write binary data to a text file !!!! so when i opened the file the program doesnt display and of my drwaing ( line,ellipse,...)

PLZZZZ..MR DAVE..SEND ME BACK AS SOON AS U CAN..!!
Regards; Smile | :)

Good luck with that!

BTW, the code you posted doesn't write ANYTHING to the file. All it does is open it. It doesn't even close the file when it's "done".

Seriously, you're missing a ton of basic knowledge you MUST have to build applications with.

thanks for ur effort mr Dave..god bless u bro..but remember i said iam TRYING to save the pic by entering binary data to text ..but i couldnt .. Confused | :confused:

..i just can creat atext but it doesnt recieve any values... D'Oh! | :doh:

comone ..i need ur help mr Dave !!

Well, I would start by never saving an image as a text file.

Next, have you looked as the Save[^] method on the Bitmap class.

iam so greatfull for ur help mr Dave ..who said i wanna to save image ..okie i just wanna to save my drawings in picturebox (lines,ellips,...) so i can display it again ..like the Paint..
iam waiting ur reply...
Regards ; Sleepy | :zzz:

If you can't get the Stream classes down, this is WAY over your head. Go back to the basics.

There's nothing that does this for you. You have to keep track of the mouse position, where the mouse buttons were held down and where it is now, drawing, calculating the circle, arc, whatever, drawing the new graphic to your bitmap, then updating the image displayed in the PictureBox, ...

my new save code is :
System.IO.FileStream fs = new System.IO.FileStream("c:\\testing.txt", System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite);

// create a stream writer
System.IO.StreamWriter sw = new System.IO.StreamWriter(fs, System.Text.Encoding.ASCII);

// write to file (buffer), where textbox1 is your text box
sw.Write("text");

// flush buffer (so the text really goes into the file)
sw.Flush();

// close stream writer and file
sw.Close();
fs.Close();

That's how we do it.

Try asking me if I care, first.

Next, try opening your image format in any other "paint" application, like Photoshop. Good luck with your proprietary format. Once again, the rest of the world isn't good enough for you.
