Start by making a program that will at least compile, anything is better than nothing.

#include <iostream>

int main() {
   return 0;
}

Now, heres an example of how to convert a single variable to MPH using the formula given.

#include <iostream>

int main() {
   double KPH = 50;
   double MPH = KPH * (5.0 / 8.0);
   return 0;
}

And now that you can do that, try making an attempt at the rest by yourself. Although admitedly, I don't quite understand what you mean by "convert an array to MPH if data represents KPH"... is that an array of numbers you need to convert? or a string..? :icon_cheesygrin:

First of all, don't use void main, theres just no need, and main always returns int.
If I understood correctly, I think your teacher wants you to make a simple loop to display the characters 10-12, without cycling through the rest.

#include <iostream>
using namespace std;

int main() {
   char test[15] = {'T', 'h', 'i','s', '_', 'i', 's', '_', 'a', '_', 't', 'e', 's', 't'};
   int row;

   cout << "Characters 10-12 are:"<<endl;
   for (char row = 9; row < 13; row++) {
      cout << test[row];
   }
   cout << "\n" <<endl;
}

Hope this helps.

>Did not you learn that variables start with alphabets and _?
How did I not notice that :).. Well spotted.

Would you mind posting the entire code?..

Careful with http://www.penisland.net/, change it to .com, and you've got yourself a problem ;o

I assume the test fails to take consideration of age?..

For the first one, I got an IQ of 120 :)
Woo! I have "High Intelligence".. only 10 away from superior intelligence.

Haven't done .NET in a hell of a long time, but doesn't it go something like this?

[DllImport("DLLNAME.dll")]
static extern void FUNCTION_NAME(PARAMS);

May not be right, but I hope this helps.

be thankful :) , email subscriptions don't even work for me ;o

>Do you hack pokemon games as well?
Thats not even worth a reply.. :icon_eek:

>and was wondering if anyone else does
I highly doubt it.

thats probably true ;) (just got 407)

Perhaps read the text from the text box into a string, and use std::stringstream to break it up.

Perhaps if you had read the rules and used code tags, I would be a little more encouraged to help.. Read This Before Posting

What annoys me more is the dumb Smily Central thing, every time I hover my mouse over it, I get the annoying disruptive "hellooooooo" sound..

If you have to write your own square root function, I would recommend the Babylonian method.

100 Reasons why Evolution is so stupid
Some good points are mentioned in this (rather long) video, but no where near enough to stop me believing in evolution :icon_cheesygrin: but personally, I dont think he knows what hes talking about 95% of the time :)

You Are 35% British
You're about as British as a half hearted Anglophile... in other words, a piss poor Brit.
If you are indeed from Britain, you probably consider yourself a European more than anything else.

If you're trying to pass for a Brit, you're going to have to try a little harder.
Go to a football match. Drink until you puke. And head in to work the next morning totally hungover.

I woulden't consider myself a prodigy, I guess im just well motivated. :icon_cheesygrin:
A friend of mine showed me flash (AS2) when I was about 12, which got me quite interested x]
I then moved to C++ about 1-2 years ago which I have stuck to ever since. But I was interested in computers and eletronics way before I started coding.

Well, I found this amusing :]

Well, considering that im 15 years old and have been coding since about the age of 12, don't have a job and am free to do pretty much anything I want :D I code when I have nothing else to do (or feel like it), so I woulden't say it 'takes my life', I have many hobbies and would say its more of an addition to my life. :)

Trig isn't all that difficult.. I put together a small example of how to create a bitmap, draw a circle and a sector in it (with a 50 deg angle). I tried to keep the code as short as possible, but it is still over 200 lines, so I will post the important part and attach the whole code. It should draw on the bitmap and save it as circle.bmp in the project folder.

const double PI = 3.141592;
const double deg_to_rad = PI / 180;
const double rad_to_deg = 180 / PI;

void draw_sector(Bitmap &bmp, int deg_startangle, int deg_finangle, int radius) {
   int centre_x = bmp.width / 2;
   int centre_y = bmp.height / 2;

   // Start Angle
   bmp.line(
      centre_x, // x1
      centre_y, // y1
      int(centre_x + cos(deg_startangle * deg_to_rad) * radius), // x2
      int(centre_y + sin(deg_startangle * deg_to_rad) * radius) // y2
   );

   // Finish Angle
   bmp.line(
      centre_x, // x1
      centre_y, // y1
      int(centre_x + cos(deg_finangle * deg_to_rad) * radius), // x2
      int(centre_y + sin(deg_finangle * deg_to_rad) * radius) // y2
   );
}

int main() {
   // Create Bitmap object
   Bitmap bmp(500, 500);

   // Centre of bitmap
   int centre_x = bmp.width / 2;
   int centre_y = bmp.height / 2;

   // Radius of circle
   int radius = 150;

   int x1, y1, x2, y2; // Temp location variables

   // Set default old coordient
   x2 = centre_x + radius;
   y2 = centre_y;

   cout << "Drawing circle with a sector of 50 deg\n";

   // Draw a circle ( loop from 0 to …

Whats with the sudden upsession of farts? :D ;)

That was just my example, if you code it yourself, you will probably be able to execute notepad before it opens.. remember my code was just an example of how to make an external program a child window within your window.

I've got a working program with a child window setup the way I want it, but now I want to make that child window an external program such as notepad. Any ideas?

Thats what my original code did.. :idea: try doing what I said, the notepad window my not be visible at first, but thats because of painting problems, try minimizing and restoring the window, then you should see it. Heres a couple of screenshots showing before compiling & running the program, and after.

i think you should try including
iostream too.

No need, theres no references to anything in iostream yet.

On line 47, you try to use the member BasicHandphone::smsStatus, which you commented out.. so by uncommenting it, you remove that error. You also fergot to add the prototype for the operator>> function, so change you class like this.

class BasicHandphone {
private:
 
   int f; 
   int smsStatus[10];
   int inboxCount;
   string sms[10];
   string smsDraft;

public:
   BasicHandphone()
   {int f = 0;}
   void draftMessage();
   void showInbox();
   void readMessage();
   [B]string operator >>(BasicHandphone & g);[/B]
   string operator + (BasicHandphone &);
};

Embedding is always done with OLE.

... care to explain why? :?:

This worked great for me.. http://69.10.233.10/KB/architecture/lint.aspx
Otherwise, your going to have to be abit more specific on what you want here.

Can you post some code where you are using the _tcscat_s function?

Code this small can easily be embedded into your post, so in future, do it :icon_wink:

you are right ....i'm still in the process to understand c++.....i want to make a game that involve throwing or launching of an object but it must have at least one obstacle partially obstructing the throwing path (for example: a high wall) and at least one other difficulty for the player, such as passing birds(which get in the way), or an environmental effect such as wind. can you help me with that... ?

Hehh.. good luck with that.. :icon_wink:

I seriously recommend you buy a book on C++, as you clearly don't know how difficult it is to accomplish something like this. Take a look at this thread. http://www.daniweb.com/forums/thread70096.html

As far as I see here it should be: notepad = FindWindow(NULL, "Notepad");

Nope, the first parameter is the class name, which in this case is "Notepad", the second parameter is for the window name, which if you don't know, can be left as NULL, although I guess you could set it to the default "Untitled - Notepad", however the caption isn't guaranteed to be this, as once you open a file, it changes.

>'FindWindowW' : cannot convert parameter 1 from 'const char [8]' to 'LPCWSTR'
> 'MessageBoxW' : cannot convert parameter 2 from 'const char [26]' to 'LPCWSTR'
> 'CreateWindowExW' : cannot convert parameter 2 from 'const char [13]' to 'LPCWSTR'

Turn off the unicode character set, you can do this a few ways, either change your compiler settings, or at the very beginning of your code (before the includes) add:

#undef UNICODE

Not another one.. http://www.daniweb.com/forums/thread139990.html

This to me seemed like quite an interesting idea, so I had a go at it. The only real problem I had is painting problems (which can probably quite easily be sorted out). This sample program will assume that notepad.exe is already open before this program is executed. It then sets notepad as a child window of the main window I made. Heres the code:

#include <windows.h>

const char ClassName[] = "WndClassName";

HWND notepad;

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
   switch (msg) {
      case WM_CLOSE:
         {
            DestroyWindow(hwnd);
         }
         break;
      case WM_CREATE:
         {
            // Find notepad.exe window
            notepad = FindWindow("Notepad", NULL);

            // Check if notepad exists
            if (!notepad) {
               MessageBox(hwnd, "Notepad not open, closing", "Error",
                          MB_OK | MB_ICONERROR);
               DestroyWindow(hwnd);
            }

            // Set it as a child window
            SetParent(notepad, hwnd);

            // Resize and position it to make it visible
            SetWindowPos(notepad, NULL, 0, 0, 300, 300, NULL);
         }
         break;
      case WM_DESTROY:
         {
            PostQuitMessage(0);
         }
         break;
      default:
         return DefWindowProc(hwnd, msg, wParam, lParam);
   }
   return 0;
}

int CALLBACK WinMain(HINSTANCE hInstance,
            HINSTANCE hPrevInstance,
            LPSTR lpCmdLine,
            int nShowCmd) {
   HWND hwnd;
   WNDCLASSEX wc;
   MSG msg;

   wc.cbWndExtra = 0;
   wc.cbClsExtra = 0;
   wc.cbSize = sizeof WNDCLASSEX;
   wc.hbrBackground = (HBRUSH) COLOR_WINDOW;
   wc.hCursor = LoadCursor(NULL, IDC_ARROW);
   wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
   wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
   wc.hInstance = hInstance;
   wc.lpfnWndProc = WndProc;
   wc.lpszClassName = ClassName;
   wc.lpszMenuName = NULL;
   wc.style = 0;

   if (!RegisterClassEx(&wc)) {
      return 1;
   }

   hwnd = CreateWindowEx(
      WS_EX_APPWINDOW,
      ClassName,
      "Window Owner",
      WS_MINIMIZEBOX | WS_MAXIMIZEBOX|
      WS_SYSMENU | WS_CAPTION | WS_THICKFRAME,
      CW_USEDEFAULT, CW_USEDEFAULT,
      CW_USEDEFAULT, …

My recommendation for you..

Another way to do this.

#include <iostream>
using namespace std;

class Item {
private:
   int node;											

public:
   Item();
   Item(int);
   operator int();

   ~Item();
};

Item::Item() {
   node = 0;
}

Item::Item(int n) {
   node = n;
}

Item::operator int() {
   return node;
}

int main() {
   Item* items[10];

   items[0] = new Item(5);
   items[1] = new Item(3);
   items[2] = new Item(4);
   items[3] = new Item(9);
   items[4] = new Item(2);
   items[5] = new Item(0);
   items[6] = new Item(6);
   items[7] = new Item(1);
   items[8] = new Item(8);
   items[9] = new Item(7);

   for (int i = 0; i < 10; i++) {
      cout << *items[i] << endl;
   }

   cin.ignore();
   return 0;
}

Whenever an variable (type Item) is used, it will be recognized as an int by what is returned from the Item::operator int() function.

Post some code which shows the Item class please.

>make a simple program
If its so simple, why can't you do it?, or at least make an attempt at it.
All you need to know to be able to do this, is how to use nested loops and from there i'm sure you could figure it out yourself.

Why dont you read the link you gave us??!
