Hi,
I have implemented a control dragging system.
Basicly i'm dragging panels inside a panel.
The thing is that i decided to put an image in the main panel background.
But that makes my other panels leave a trail when i drag them.
Does anyone has an explanation/solution for this?
Thx,
Nuno

...A persistent trail? Meaning, it ghosts the panel all over the place and they artifact the screen? Try putting your panels inside a BufferedGraphics object(you need to double buffer your screen display....a BufferedGraphics object will implement the backbuffer for you)

Hi,
Thx for your reply.
Can you point me an example?
Thx,
Nuno

...just check out the BufferedGraphics entry in the msdn. That should get you started...repost in this thread if you still need further help after that and I'll see what I can pull up for you.

Oh....btw, are you using .NET 1.1 or .NET 2.0? ...The BufferedGraphics object is only available in 2.0

Hi, do you have c# program that draw cube?
Noha.Y

no...It doesn't work that way: But you can
look into Microsoft's XNA framework, and you can look up Direct3D tutorials. Building a 3D cube will be one of the first things you will build
or
do it the old fashioned way...register a Win32 Window, register your callback and message loop, and hack away inside your render code to build a cube(in Direct3D, OpenGL...or whatever graphics library you like)
My suggestion would be to look into the XNA. You'll be able to execute your DirectX code inside the CLR, so all of your resources will be inherently Managed.

How can I enter to XNA is?

Can you give me another website to find directX and OpenGL? because my computer is not able to enter to www.gamedev.net
Thanks;

...are you at work or something? I can't think of any other sites for certain. ...I'm sure GamaSutra would have tuts. ...Other than that, some simple web research should find tons of simple examples.
Typically, tutorials follow this kind of structure:
1.They'll start you off building the window...
2.You'll draw a 2D triangle
3.You'll rotate that triangle
4.You'll build a 3D cube
5.You'll build Halo
6.Sell Halo for $30,000,000 , call John Carmack and go "HAHAHAHAHAHA"
7.Start your own Gaming company
8.Get hot chicks

...I saw a post that you made earlier asking the same thing, but you specifically mentioned OpenGL, but you mentioned in this post that you specifically want to write in C#. If you REALLY want to write OpenGL code in C#, you're going to need to get the CsGL library from sourceforge. ..Only problem is that the project was ended back in 2003. If you run into any problems, it might be a bit difficult to find any support at all, especially since you don't know OpenGL coming into it. If you want to write OpenGL, you're probably going to want to write it in either C or C++. There are several toolkits available to make your life easier...especially the GLU, & the GLUT. ...There are 2 major reference manuals that you're going to want to get. They're called the "Red Book" and the "Blue Book" (There's also a "Green Book", an "Orange Book" and the "White Book") but the Red and Blue will get you started. You can find deprecated copies of Red and Blue all over the place.
Red is the Programming Guide
Blue is the Reference Manual
Orange is for the OpenGL Shading Language(Don't worry about it for now)
Green is for X Windows programming
White explains how OpenGL interfaces with Windows (95 & NT specifically)

Nice... I started with the Red Book, but my problem was how to start a new project. I mean what to choose? and how to initial the classes!!

Check out the tutorials at Nehe. They're pretty good, and C# source code is included for most tutorials...
Standards are great! Everybody should have one!
|
|
|
|
|
..Nehe is maintained by gamedev.
...what implementation of the OpenGL spec are you using? ...Which spec does your implementation build off of? Are you using Mesa? Glut? CsGL? ...Try going to opengl.org. There should be information in their wiki as well as getting started information

Is there a routine in C# that can be called to obtain a randowm number?
I am attempting to name many files with unique names. Do not want to use a counter writing to disk each time. Does anyone know of a unique number random generator in C#
|
|
|
|
|
System.Random
Though I don't believe this will work for your application as depending on the number of files and seed value, the possiblity of getting the same random number is likely.
System.IO.GetRandomFileName may be better in this case.
only two letters away from being an asset
|
|
|
|
|
I will try to use System.IO.GetRandomFileName
have a question though... will this be truly random, and not repeat at least within a large number of files generated , like maybe, every 1000 files names?
|
|
|
|
|
the next number after 13 in a truly random sequence can well be 13 again. If not,
it would not be a truly random sequence.
For non-conflicting filenames, you MUST include a trial-and-error loop, since
whatever scheme you come up with, the filename you generate may already exist.
|
|
|
|
|
In order to use GetRandomFileName, do i have to use anything but System.IO?
It says it is not a member.
If i do System.IO.GetRandomFileName OR Path.GetRandomFileName
|
|
|
|
|
This available only in 2.0 and higher
only two letters away from being an asset
|
|
|
|
|
maybe a GUID[^] is what you're looking for
|
|
|
|
|
System.IO.Path.GetTempFilename[^]
This returns the full path in the user temp directory, though, so it may not be what you are looking for.

why are you creating random numbers
why dont you take an interger and increment it every time for every time the file name already exists
if you are dealing with larger number of files prefix or suffix ddmmyy to that number

It is Good to be Important but!

[My Question]

I'd concur with an earlier poster, use a GUID. In my experience the System.Random class isn't all that random, at least so far as generating 1000's of numbers a minute, unless you provide a good variation of seeds.
I'm largely language agnostic
After a while they all bug me
