Look at line 30 in error.c file; it's probably a typographical error.
If not, post the code segment.

I coded a bubble sort (below) and it works when I run it through Visual C++ but when I open it manually in XP the window opens and lets the user enter data and it quits quickly afterwards without displaying the output.
#include <iostream>
#include <iomanip>
using namespace std;
//Macro for max size of array
#define MAX 50
int Array[MAX];
int main()
{
cout << "\n----------------BINARY SORT ALGORITHM-------------------\n" << endl;
//Code for entering data into array
cout << "Enter up to " << MAX << " integers. " << "(Quit with any letter):\n" << endl;
for(int i = 0; i < MAX && cin >> Array[i]; ++i)
;
int ArraySize = i;
//Display Array
cout << "\nArray Size:- " << ArraySize << "\n" << "\nArray:- ";
for(int ii = 0; ii < ArraySize; ii++)
{
cout << setw(5) << Array[ii];
}
cout << "\n\n";
//Flag to show if sorted or not
bool Sorted = false;
//Temporary store whilt swapping
int Swap;
while( !Sorted )
{
Sorted = true;
for(int iii = 0; iii < ArraySize; ++iii)
{
if( Array[iii] > Array[iii + 1])
{
//Prints out current state of array
for(int j = 0; j < ArraySize + 1; j++)
cout << setw(5) << Array[j];
//Swapping code
Swap = Array[iii];
Array[iii] = Array[iii + 1];
Array[iii + 1] = Swap;
cout << "\n";
//Flag false since swapping occured
Sorted = false;
}
}
}
//Output
cout << "\n\n" << "SORTED LIST\n";
//Counter in the loop and condition are adjusted to ignore first element which is always 0 and to include last element
for(int iiii = 1; iiii < ArraySize + 1; iiii++)
cout << setw(5) << Array[iiii];
cout << "\n\n" << endl;
return 0;
}
Thanks

Hallo,Before all i want to say sorry to my poor english.
I'm little new in this kind of develop like C++, and i'm trying to do a client server in visual c++ where i have to do a connection with the login of one user that previous is registered (but it's not my problem).When i have the user login, with this user i have to send the information to the server and the server will say me what access i have, like if i have access to different devices like USB, cd-Rom,..( it's my real problem, how can i restrict the different kind of devices?) or what files have i access to download to my client and i think that here i have to implement Encrypt of files.
Somebody can say me how can i do this or which libraries can i use or a idea of like implement this problem.
Thank you very much and i hope that you can help me.

How can I send an escape sequence to the printer?
I'm working with the C++ Builder and the VCL is not supporting escape sequences.
So I tried these snippet
char Help[1024];
sprintf(Help, "\x00c"); // escape sequnce for form feed
Escape(printer->Canvas->Handle,
PASSTHROUGH,
sizeof(Help),
Help,
NULL);
But the printer is not doing anything.
Thanks for your help!

Sorry that I posted the question to a wrong article already

I don't believe that C++ Builder supports managed C++

does anyone here have a managed c++ sentence parser? i just need it... i have a sentence parser in c++, but i dont know how to convert it into managed c++, does anyone here know how to do it?
thanks for your replies

Well, the following works in C#:
static void Main(string[] args)
{
string myString = "Just words, please.";
char [] seperators = {' ', ',', '.', '?'};
int startPos = 0;
int endPos = 0;
do
{
endPos = myString.IndexOfAny(seperators, startPos);
if(endPos == -1)
{
endPos = myString.Length;
}
if(endPos != startPos)
{
Console.WriteLine(myString.Substring(startPos, (endPos-startPos)));
}
startPos = (endPos + 1);
} while (startPos < myString.Length);
}
And you can get a C# string in C++ as follows:
#pragma push_macro("new")
#undef new
String* str = new String(S"Just words, please.");
#pragma pop_macro("new")
There must be a way to put them together.
Good luck.
Sincerely,
-Ron

Hi, I am building a Testing tool using C++.net for college. I need to
get a very accurate measurement of a c functions execution time.
Currently I am running the function as real-time process and using the
QueryPerformanceCounter to measure its time, however this is still not
very accurate (between 1 and 5% inaccuracy). Any ideas on how to
improve this would be much appreciated.

I was recently messing around with this approach, and I found the results to be unverifiable. I was using the high fidelity system time stamp retrieved from a CounterSample (I suspect that you did something similar). The MSDN documentation states that the timestamp has an accuracy of a tenth of a millesecond.
I found this article over in the MSDN Magazine archives, maybe it will help:
http://msdn.microsoft.com/msdnmag/issues/04/03/HighResolutionTimer/default.aspx[^]

|
|
LARGE_INTEGER startCount, endCount, freq;
QueryPerformanceFrequency(&freq);
QueryPerformanceCounter(&startCount);
YourFunc();
QueryPerformanceCounter(&endCount);
printf("Elapsed time = %lf", (double)(endCount-startCount)/freq);

Is is possible to create an object that inheriets from a MFC object in .NET?
|
|
|
|
|
|
While this article does address using C++ in .NET, it fails to address inheritience.
|
|
|
|
|
What do you mean by "inheriets in .NET?" What is different about your derived class that makes you ask this question? Is it in a language other than C++? Is it under the CLR's control?
Sincerely,
-Ron

I have a managed class called ConfigManager, with a static method:
static void StartService()<br />
{...}.
When I compile, the compiler changes the method name to
<br />
static void StartServiceA()<br />
{..}.
If I change the method name to StartServiceBlaBla, the compiler doesn't change it.
Any one has an idea?
Thanks,
Yaakov

When you include windows.h it defines some macros. One of them is like this:
#define StartService StartServiceA
This is used to replace the windows function StartService with the non-unicode version of it. To get around this problem you can either rename your function or include the following line after you include windows.h.
#undef StartService

Does anyone know how to find a local group's permissions? I am enumerating through the local groups on my machine using the NetLocalGroupEnum API, but when I check the group using the NetLocalGroupGetInfo API, I only get two pieces of information that I don't need:
1 The group's name - already have, don't need again
2 The group's description - doesn't serve my purpose
Are there any APIs or methods that I can use to find if a local group is an admin group? I've spent many many hours working on this problem and I am getting a little frustrated.
