Then perhaps you'd be willing to post a link to the movie, rather than instructions on how to create our own.

I think this is a problem that a CP would like.
So I post it here to discuss a way to solve my question.
I also want to code some code to do something like that

The maze is quite interesting, is it wolfenstein?. It is interesting to know of a way to transfer binary via debug.
cool.
But could be risky as well

It is interesting, I tested on a test machine with network disconnected. Next time you want to post such thing, you need to explain what it does, if you can't, attach a warning message that this is an uncheck code. Such code does carry a lots of risks.
Good try anyway, thanks!

You can't be paranoid enough. I installed some free innocent looking animated icons on my Windows laptop. A month later, when I installed and activated Norton Internet Security, I was notified the free software was trying to send information back to its web site. I assume it was marketing spyware but it could have been even worse.
My question - How do you know your disconnected computer won't do something evil when it is reconnected to your network?
I recently diagnosed a customer computer that wasn't shuting Windows down gracefully. I used MSCONFIG.EXE in the Windows directory and looked at all the programs being loaded. The cheap Juno Internet service had marketing spyware installed telling them what topics were of interest to the customer. Consequently, when the customer went to a automobile quote site, he started getting automobile popup adds and automobile sales email.
Of course, such programs tie up ram memory and slow down the Windows startup.
The following site provides a list of all programs detected as running covertly during Windows startup. It also explains their removal techniques.

My answer
It never is. More accurately, I have a Ghost Image of a known clean configuration, which I restore to a drive, put stuff on for testing/checking, then restore again to wipe all traces of whatever it was.
After all, the last thing I need is any kind of virus/worm infection....

I am trying to use a struct as a parameter to a template. I am trying to use the struct as an abstract interface to a plugin architecture. The problem is that I can't seem to instantiate it correctly. Here is the code below. Any ideas what I am doing wrong. All the example for templates seems to exclusively use stack for there example.
// Here is how I am trying to instantiate it
CPlugin<I_Plugin>PLUGIN;
PLUGIN.Load("HTPCPlugin.dll", "GetPlugin"); // compiler pukes here

Hi smesser,
Brackets do not show properly in your post. Please use the "Do not treat <'s as HTML tags" checkbox below the editbox. Also, what is the error messahe the compiler is emitting?

Sorry about that. I did as you sugguested and I also added the compilers errors.
Thanks

In which context are you issuing the PLUGIN.Load() call? Inside a function or outside?
Joaquín M López Muñoz

|

At the moment I was using it outside all functions (globally) just to see if I could get it to complile.
|
|
|
|
|
Then don't You cannot write code outside a function just like that. It is like if you dropped a printf("hello") outside a function, you get this is not legal, right? Put your code inside some function and things will probably work (or at least your error chasing will move one step further.)

You can have the plugin loaded without any "inside" code if you define the ctor as
CPlugin(const char* szDLLName, const char* szFunction){}and provide some GetPlugin accesor for later use. IMHO this is probably better than the Load scheme, since the only purpose of CPlugin is to make the loading anyway. Following this approach, you might want to move the unloading code to the dtor of the class and supress the explicit loading functions altogether. This fits nicely with a C++ idiom called RAII (Resource Acquisition is Initialization), which you can google for for further info.

Thanks for the sugguestion. I will look into it.

Ok, I just put:
PLUGIN.Load("HTPCPlugin.dll", "GetPlugin");
inside of a function and it compiled beautifully.
I am new to templates so what is going on here?

There is surely something I do not understand here. I would very much appreciate if someone could explain to me how I screwed this up.
Thank you.

Well, I am comming along more and more with this program, but I could still obviously use some help. I am going to put the specifications in full out here.
Define a class for triagnles. A triangle is defined by three sides. Class should have following capabilities:
A constructor that will allow definining a triangle. (float side1, float side2, float side3). The constructor is to call Order to place the sides in order from smallest to largest.
A constructo with no arguments: initialize the three sides to zero.
Public member functions needed.
void SetTriangle(float side1, float side2, float side3);
bool IsEquilateral();
bool IsIsosceles();
bool IsScalene();
bool IsRight();
bool IsAcute();
bool IsObtuse();
friend Triangle Copy(Triangle triangle1);
friend bool operator ==(const Triangle& triangle1, const Triangle& triangle2);
friend ostream& operator <<(ostream& outs, Triangle& the_triangle);
Private member functions needed.
void Order;
void Swap;
I need to write a program that will define triangle1, triangle2, triangle3, triangle4
am to define a class for triangles, and once I have defined it I need to do tese procedurse:
The constructor (with sides) is to call order to order the sides from smallest to largest.
and
The SetTriangle function is to call order to order the sides from smallest to largest
and then display the sides and the type it is... scalene and right, isosceles and acute, ....
I think I may need to give more detail. Triangle1 will not have any values defined. Triangle2 has sides 6.0, 6.0, 6.0. Triangle3: 5.0, 4.0, 3.0. Triangle4: 6.0, 4.0, 4.0
And then for Triangles 2, 4, and 4... I
1) Use friend operator function << to display the three sides of each
2) Test to see if the triangle is Equilateral, Isosceles, or Scalene. When one of the functions returns true, display message. Message should not be displayed within function.
3) Test to see if Right, Acute, Obtuse
For the copy test
1) Use the friend copy function to copy triangle 4 to triangle 1
2) Use friend operator function << to display the three sides of triangle 4 and triangle 1.
3)Use friend operator function == to see if triangle 1 is equal to triangle 4. If the two are, display " are equal", otherwise " are not equal.
For another == test, do the following
1)Use friend operator function << to display three sides of triangle2 and triangle3.
2)Use friend operator function ++ to see if triangle2 is equal to triangle3 and display appropriate message
For the SetTriangle test, do the following:
1)set Triangle3's sides to (5, 4, 3 (in that order))
2)use friend operator function << to disply the three sides of triangle3.
There are all the specifications and what not. It has been like a week... and I have only gotten as far as this Could I please get some help all around on this one. I would so much appreciate it. Please, could I get some help. I have done this much on my own, and now I have just gotten stuck and don't really have a clue as what to do.

OK, let me see, if i understood you correctly.
You want to use an overloaded operator << . But what you have done, is only using the normal output of an float.
The overloading would look like this:
ostream& operator<< (ostream& ostr, CTriangle& triangle)
{
ostr << "Side1 = " << triangle.side1 << endl
<< "Side2 = " << triangle.side2 << endl
<< "Side3 = " << triangle.side3 << endl;
return ostr;
}
The overloaded operator== looks like this:
bool operator ==(const CTriangle& tri1, const CTriangle& tri2)
{
if (tri1.side1 == tri2.side1
&& tri1.side2 == tri2.side2
&& tri1.side3 == tri2.side3)
return true;
else
return false;
}
My personal advice:
You should divide your program into three files.
-----------------------
First file -
a file containing the declaration of the triangle class. Name this file triangle.h
!! Remember that triangle is a class, so name the class CTriangle. !!
-----------------------
Second file -
Name this file triangle.cpp
include your triangle.h by using
#include "triangle.h"
Now put all the definitions of your CTriangle class in here (for instance yout get-functions etc. and the overloaded operators). Don't forget neccessary inclusions like iostream.h
-----------------------
Third file -
name this file main.cpp
include your triangle.h by using
#include "triangle.h"
#include <iostream.h>
void main()
{
CTriangle triangle1, triangle2(5.0, 4.0, 3.0), triangle3(6.0, 4.0, 4.0);
cout << "Display triangle 1:\n";
cout << triangle1 ;
cout << "Display triangle 2:\n";
cout << triangle2 ;
cout << "Display triangle 3:\n";
cout << triangle3;
if (triangle2 == triangle3)
cout << "identical" << endl;
else
cout << "not identical" << endl;
<
}
I havent compiled it, but this should work. Test it by changing the values of the triangle2 and triangle3.
Hope this helps

heres my problem
float r=10.3;
int x=10;
int z=ceil(r*x) gives me 104 . I need 103
I need output to be converted as
if product = 103.1 o/p = 104
if product = 103.0 o/p=104
if product = 103.5 o/p = 104
Basically i dont want it to take the upper no if the product can be equivalently represented by an integer
what i mean is 103.0 is actually 103
but 103.1 isnt 103

|

Hi
double r=10.3;
int x=10;
int z= ::ceil(r*x);
will give 103
