#include <iostream>
using namespace std;
int main()
{
cout << "Hello World" << endl;
}
this will output as:
Hello World

Nope. Don't you need to #include <iostream>
Currently this is what I have
#include <iostream>
using namespace std;
void main()
{
cout << "Hello World." << endl;
}
But getting a lot of
c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\cerrno(16): error C2143: syntax error : missing '{' before ':'
c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\cerrno(16): error C2059: syntax error : ':'

c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\cstdlib(15): error C2059: syntax error : ':'

Got this to work
#include <iostream>
int main(){
std::cout << "Hello World" << std::endl;
}

I forgot to check th 'do not treat carrots as tags box' :P
so this is what i meant

k, got some windows related questions here,
1.I have this folder:
C:\Documents and Settings\my username(hidden for obvious reasons)\Local Settings\Temporary Internet Files
why can't I delete it?
1.if I go into cmd.exe and delete it it works but after that it is created right away. Why?
2.there are some files in this directory that I can delete from explorer.exe but not from cmd.exe or from my own program. Why? and how can I delete these files from my own program that I make and I want to delete them from it?

1) You may need to make sure they are not set to read-only!
2) Your security access may not be set to allow you to delete them!
3) cmd.exe did not delete them it just acted like it did (for some reason).
Sure you could try to write your own program to delete them, but the problem that is stoping you will still be there and it should still not work.

It's a special "system" folder. Why is this folder troubling you?

They may be marked as read-only, hidden, or system. It may also be a permission (or lack thereof) issue.

When i compiled my program, the following error occur:
PlaySound error LNK2019: unresolved external symbol "public: __thiscall CCapture::CCapture(void)" (??0CCapture@@QAE@XZ) referenced in function _main
CCapture is just an object and I create the CCapture object in another .cpp.
I have already link the two .cpp files and included the .h files. However, the problem still exist.
How can I solve this problem?
Thank you!

You defined a constructor in the class defintion, but you haven't written the body of it - CCapture::CCapture()

I am migrating my VC6.0 code to VC .NET now. But I got some link errors because some export functions I used have CString as parameters. Is there any ways to get around of this, like any project settings? Thank you.

I am getting CString problem also. I am getting Assertion Failed.

I am trying to implement the overlay blend mode as in photoshop. I have already implemented some blend modes(screen , multiply etc). Ovrlay blend mode is a combination of Multiply and screen blends depending on the base color this i found out. But when should i apply multiply and when should i apply Screen. What are the color values of the base, Can Anybody give me the info.
Thanks, Vikash

have a look at the filters section in the SVG spec - iirc this is described quite well and may be of help. http://www.w3.org/Graphics/SVG/

Thanks I will try that but i am open to any more suggestions

I just received a call to debug a TAPI problem.
The company that created the control no longer exists.
Problem: When the VB App finished making a call and downloading via modem, it closes the program without giving a reason. This only occurs on machines running Win2000 or WinXP. The program was origanaly written and tested on Win2000 (also tested on Win3.1, Win95 and Win98).
Could this have something to do with Windows security updates?
Any ideas would be helpfull.
NOTE: I already left this same message on the VB forum.

Try this in VC++
double dValue = 10.52 - 10.0;
Normally dValue should be 0.52 but the result is always: 0.51999999999999957
Why ?????
it cause me a lot of trouble, any idea on how to fix it ?

because of precision computing.
it's standard "behaviour" when representing floating point numbers in binary.

Try this using pen and paper. It's called Long Division. Divide the value 1 by the value 3. When you get the exact answer and there is no remainder, please come back. 
If you do some Google searching for floating point approximations, you'll probably find your answer. Binary representations of a rational number requires approximations just as base ten representations of rational numbers requires approximations. Most times these approximations are very small and have only a minor or neglible effect on calculations, but as you are probably discovering, there are times that the effect can be appreciable.

It's inevitable. It is impossible to represent some real values exactly in floating-point format.
The best way to handle rounding errors like this is to decide what precision is necessary for your application and round values when necessary. Keep the values 'raw' as long as possible and round before displaying the result.
for example:
double round(double val, int ndp)
{
double mult = pow(10, ndp);
val *= mult;
return ((val - floor(val) < 0.5) ? floor(val) : ceil(val)) / mult;
}
...
double dValue = round(10.52 - 10.0, 4);

Thanks for your help.
With this simple Round function I was able to fix my problems.

why don't you just use int? or short int?
