I guess I thought Join(500) would kill the thread after 500ms. I must have misread that somewhere.

criteria exams=50% quizzes=10% daily= 10% assignments= 30%
this is the program I would like to revise
include<stdio.h>
void main (void)
{
double gpa,exam,quiz,assign,prof;
printf("\n enter the exam grade:");
scanf("%lf", &exam);
printf("\n enter the quiz grade:");
scanf("%lf",& quiz);
printf("\n enter the assign grade:");
scanf("%lf",& assign);
printf("\n enter the prof grade:");
scanf("%lf",& prof);
gpa=((exam*.6)+(quiz*.1)+(assign*.2)+(prof*.1));
printf("\n the gpa is %.2lf", gpa);
}

This is the C# Forum, not C++...
You might want to actually ask a question with whatever your having a problem with. DO NOT just say you want to revise this program. Since this is a homework project, you actually have to write the code. We'll help you with any problems your having, but will NOT write the code for you.

What Dave said. Your code is also not valid C++, it returns void instead of int. That your compiler sucks is no excuse

Is a perfect valid C/C++ program.
Compiled on VS.NET 2003 and 2005 Express , no warnings, no errors, runs correctly.
Compiled on GCC 3.4.3, gives return type warning, runs correctly.

Then you're screwed 
The C++ standard says main returns int.

Hello,
Here's my problem: I have to replace all instances of a certain string in binary values. I was using ASCIIEncoding to get the bytes to a string, performing the replace, then using ASCIIEncoding to get the string back to byte[]. This was working for most of my tests but then I ran into binary values that were getting corrupted during the conversion. I wrote the following test code:
// myRegKey is a RegistryKey object
// ValueName is a string (the name of the value I want to retrieve from the registry)
object valData = myRegKey.GetValue(ValueName);
ASCIIEncoding ae = new ASCIIEncoding();
byte[] buff = (byte[])valData;
string tmp = ae.GetString(bite);
byte[] buff2 = ae.GetBytes(tmp);
So I would expect that buff and buff2 would be identical, but they are not!
I need a way to get a byte[] to a string and then back to a byte[] without compromising my data. Any ideas?
Perhaps if someone had a method that converts a binary value to a string of hex digits? For example, "Hello World!" would become "48656C6F20576F726C6421"
Thanks,
-Ian

i guess with something like
stringbuilder sb;
string s
char[] ca
ca = s.ToCharArray(0,s.Length);
a for loop
sb.Append(((byte)ca[i]).ToString("X"));
its a lame code i know

I want to transfer a class instance on internet and encrypt this instance. But the encryption classes requieres byte[]. how can I get the byte[] representation of an instance?

I know PHP and Java, and I'm just starting to learn C#, so I don't know many of the C# methods.
I'm trying to write a method that will open a bmp image and save it on the hard drive. I want to compile the image with the program, so I added it as an item in the Solution Explorer, but now I dont know how to access it.
What method do I use to access it?
Thanks

Umm.. what exactly did u added and how?
To open a bitmap and save it somewhere else on ur machine you could say:
System.Drawing.Bitmap myB = new System.Drawing.Bitmap(@"C:\myBitmap.bmp");<br />
<br />
myB.Save("......");

In the Solutions Explorer I right clicked on my project's name then went to 'Add', 'Add Existing Item...'.
Next I selected a .bmp image and hit enter.
Does that help?

Well, not really. What you did, is just adding a specific bitmap image as a resource into your solution. If all u need is opening a bitmap during runtime and save it somewhere else, you just have to follow the small code sample I provided you with before.. or something similar.
Hope this helps

Polis

Thanks, but what path do I use to access the image?

Well, that's up to you.
I think that you would want your users to be able to specify the path to a bitmapt for themselves by browsing for a specific file or typing down the filename path for themselves. It wouldn't really made much sense to just specify a fixed filename path in your code right?
A simple example:
You could drop two textboxes and a button on your form. The users would then type a path to a bitmap in the first textbox, the new path to which the bitmap will be copied in the second textbox (if it does exists under that path), and finally press the button to actually copy the bitmap.
On the button click event you could have something like this:
Bitmap myBitmap = new Bitmap(this.textbox1.text);<br />
<br />
myBitmap.Save(this.textbox2.text);
A small tip:
Btw, you would have to provide some checkups. E.g. make sure that the path names the user provided are valid before attempting to load a bitmap. Or, make sure that the user HAS provided paths for both textboxes.

Polis

No, I'm sorry I didn't explain myself well enough.
I want to have the user copy a resource in my program, not on the hard disk, to a loction on their hard disk.
How do I access that resource?

To programmatically access one of your resources you could say something like:
Assembly myAssembly = GetExecutingAssembly();
Stream resourceStream = myAssembly.GetManifestResourceStream("myBitmap.bmp");
Bitmap image = new Bitmap(resourceStream);

I am not sure whether you can do that. Resources are part of your assembly and are included in it every time you compile your program

I didn't know you could do that but it makes sense now that I think about it.

It is cool indeed, although I have to assume your example is contrived since just using "3.1415927" would have avoided boxing the numeric value (as well as a call to the member function 'ToString()').
In general, gratuitous boxing/unboxing is discouraged because of its performance cost, although the ability to box/unbox value types clearly serves a purpose, and is ingrained into the .Net Framework - the ArrayList type is a perfect example.
