sorry forgot, here ya go, im not updating, im creating
#include <iostream>
#include <string>
using namespace std;
struct person {
string firstName;
string lastName;
int age;
double height;
};
int menu(int &menuChoice);
void userInfo(person user[], int size, int const track);
void listUser(person user[], int size, int const track);
int main()
{
int menuChoice;
int static track = 0;
person user[50];
do {
menu(menuChoice);
switch(menuChoice) {
case 1:
userInfo(user, 50, track);
track++;
break;
case 2:
listUser(user, 50, track);
break;
}
} while(menuChoice != 3);
return 0;
}
int menu(int &menuChoice)
{
do {
cout << "- Menu -" << endl;
cout << "1 - Enter user and info" << endl;
cout << "2 - List all users and info" << endl;
cout << "3 - Quit" << endl;
cout << "nPlease enter your choice: ";
cin >> menuChoice;
if( menuChoice > 3 || menuChoice < 1) {
cout << "nPlease select an existing option!n" << endl;
}
} while(menuChoice > 3 || menuChoice < 1);
return menuChoice;
}

You need to write code to save your data to the hard drive or some other resource such as a database. However, there is no simple answer on how you should save your data from memory and recovering it from an resource. If you are just creating a personal database used only by you, you still have to consider what are your immediate and future requirements. You have a primitive interface to insert records and to sequentially list them. If that is all the functionality you need, then saving your records to a comma separated file may be all that you need. You can use the Standard Library's file streams to do this. To access the file streams, you need to have: #include <fstream>. You can google the web to find examples on how to use the file streams: http://www.informit.com/guides/content.asp?g=cplusplus&seqNum=73&rl=1[^]
By the way, you are in the wrong forum. You should be in the Visual C++ forum.

1) I need code written by some body else for string concatenation without using sting functions?
2)Taking the variables from string in alphabatic order.
For example:
we r entering a word called MARK.It has to print in alphabatic order ie: MARK as AKMR.
3)write a program for printing in between numbers (Ex: 3,4,9,7,10,14,54,8) print the numbers existing inbetween 3 and 8.

If you have written some code, please ask a specific question concerning that code. A sample of your coding problem is always helpful.

I am sorry. You won't get that kind of help here. A simple string in C++ is an array of characters terminated by a NULL character. You need to write your program to operate on that array probably using pointers. So, crack open a C++ primer and get to work.

I want string programs in c++ without using string functions
1)write a program for string concatenation without using string concatenation function.
2)Taking the variables from string in alphabatic order.

Are you required to use Managed C++ for this? If not, you should post your question on the
VisualC++/MFC[^] board.

We help programmers that have specific coding issues. We don't develop code or solve homework assignments. The code written by somebody else must be written by you. You learn by doing.

i have included all necessary libraries. where i am going wrong?
Thanx in advance.

When performance is not an issue and when all that we want is just a snapshot of the desktop, we can consider the GDI option. This mechanism is based on the simple principle that the desktop is also a window - that is it has a window Handle (HWND) and a device context (DC). If we can get the device context of the desktop to be captured, we can just blit those contents to our application defined device context in the normal way. And getting the device context of the desktop is pretty straightforward if we know its window handle - which can be achieved through the function GetDesktopWindow(). Thus, the steps involved are:
Acquire the Desktop window handle using the function GetDesktopWindow();
Get the DC of the desktop window using the function GetDC();
Create a compatible DC for the Desktop DC and a compatible bitmap to select into that compatible DC. These can be done using CreateCompatibleDC() and CreateCompatibleBitmap(); selecting the bitmap into our DC can be done with SelectObject();
Whenever you are ready to capture the screen, just blit the contents of the Desktop DC into the created compatible DC - that's all - you are done. The compatible bitmap we created now contains the contents of the screen at the moment of the capture.
Do not forget to release the objects when you are done. Memory is precious (for the other applications).
Void CaptureScreen()
{
int nScreenWidth = GetSystemMetrics(SM_CXSCREEN);
int nScreenHeight = GetSystemMetrics(SM_CYSCREEN);
HWND hDesktopWnd = GetDesktopWindow();
HDC hDesktopDC = GetDC(hDesktopWnd);
HDC hCaptureDC = CreateCompatibleDC(hDesktopDC);
HBITMAP hCaptureBitmap =CreateCompatibleBitmap(hDesktopDC,
nScreenWidth, nScreenHeight);
SelectObject(hCaptureDC,hCaptureBitmap);
BitBlt(hCaptureDC,0,0,nScreenWidth,nScreenHeight,
hDesktopDC,0,0,SRCCOPY|CAPTUREBLT);
SaveCapturedBitmap(hCaptureBitmap); //Place holder - Put your code
//here to save the captured image to disk
ReleaseDC(hDesktopWnd,hDesktopDC);
DeleteDC(hCaptureDC);
DeleteObject(hCaptureBitmap);
}
In the above code snippet, the function GetSystemMetrics() returns the screen width when used with SM_CXSCREEN, and returns the screen height when called with SM_CYSCREEN. Refer to the accompanying source code for details of how to save the captured bitmap to the disk and how to send it to the clipboard. Its pretty straightforward. The source code implements the above technique for capturing the screen contents at regular intervals, and creates a movie out of the captured image sequences.
In consideration to the above code please let me know how to capture the network PC`s desktop to my software..
I want to capture it continously i dont want to save it, i want it`s Rectangular Area in ma software...
Please let me know how to do this(of course sockets are used) or create a method for this...

Can someone help me with the link errors in this[^] project.
I was tryin to resolve this from last friday with no success. Would be gr8 if someone can compile this for me without errors. It gives me link errors whenever I use TIFFReadRGBAImage, but once I comment it out there are no errors. Any help...!!
-thanks.

Obviously, you're not linking to the TIFF library properly. If you're using C++/CLI, you have built in tiff support. If you're not using .NET, you can still use GDI+, but you'd then be in the wrong forum.

It looks like you forgot to add the proper library in the linker command line.

Hello everyone,
I'm want to build a Gpib drivers for an Agilent instruments.
Now...I want it to be a "class a-like" driver , for example if the user wants to set a center frequency of 100MHz in a spectrum driver it will look like this:
...
// defenition
Agilent_Spectrum spectrum;
// initialization
spectrum.init(9);
// send a frequncy
spectrum.frequncy.center.MHz=100;
...
The question is : can I do it without using classes ?
|

|

Using just plain C you can do whatever you want. It's enough to you, isn't it?

The answer would be, if you're not using classes, you're probably not using C++/CLI, so you must be asking in the wrong forum.

(I do work in c++, and I do know how to use classes...classes is the answer for my problem but it's a lot of work).
I didnt say that Im not using classes...I said I want to do it without using classes...meaning:
the question is "can I do it in a simple and more primitive way ?" maybe something like "namespace" or structures ?
|
|

Yes, I can see that you're working in C++, but, again, this is the C++/CLI forum, and you are not using C++/CLI as far as I can see.
Of course you can write anything you like without using classes, just like I can walk to the store instead of driving. You are not forced to use the tools that make yuor job easier.
Oh, and a struct IS a class, they are the same thing, the only difference is the default access modifier.

I made my algorithm in visual c++2005, now I want to do an interface in VC++2005 to this algorithm but the code has only functions not classes or something like this and I put my functions in the main application source file(forminterface.cpp) ...a short example is written like this...:
#include "stdafx.h"
#include "Form1.h"
using namespace forminterface;
.................
void prepareitems(item *f, item *l, int *w, int *h, int *d, int *ra, int *rb, int *rd)
{
item *i;
int k;
for (i = f, k = 0; i != l+1; i++, k++) {
w[k] = i->dx; h[k] = i->dy; d[k] = i->dz;
ra[k]=i->rx;rb[k]=i->ry;rd[k]=i->dz;
}
}
..............
[STAThreadAttribute]
int main(array<system::string ^=""> ^args)
{
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
// Create the main window and run it
Application::Run(gcnew Form1());
return 0;
}
I want to call this function in my "start button"(private: System::Void StartPackingbutton_Click(System::Object^ sender, System::EventArgs^ e) {} ......of the interface but I don't know how or if I must declare this function in other place because it give me error like"prepareitem is not a member of global namespace"....please help me I am disperate ...I don't know where to put the functions of my algorithm and in this way to make the conection with my interface...

Looks to me like it's not visible from where you call it ( assuming that it's prepareitems and not prepareitem in the error ). Why not wrap this in a class, so you have a header file you can include to make it visible ?
