What does that mean ?? C++ is just a programming language so you cannot 'run' it. You mean you tried to compile one of your program with .NET ?

What is fatal error ?
Could you be more specific ?

this program accept user input like an app-oin-tment book, at the moment can only take one date. i am just learning the programming ,it wil be great
the prog. is as follows:
#include "stdafx.h"
#using <mscorlib.dll>
using namespace std;
class Day{
private:
int day,month,year;//Date
public:
Day(int,int,int);//Constructor
~Day();//Destructor
void display();
};
Day::Day(int d,int m,int y){//Pass date to constructor
day=d;month=m;year=y;//Set the date
}
Day::~Day(){}
void Day::display(){
std::cout<<day<<' '<<month<<'="" '<<year<<std::endl;="" display="" day
=""
}
int="" main(){
="" int="" d,m,y;
="" std::cout<<"please="" input="" the="" date="" :\n";
="" std::cin="">>d>>m>>y;
Day MyDay(d,m,y);//Create a day
do{
MyDay.display();
}
}

|

sorry guys
what the programm does it suppose to take multiple date from users.
eg 12/12/2006
13/12/2006
14/12/2006
and so on.

First explain your problem clearly, the only thing I see here is code and a very brief description of what your program should do. But what is actually the problem ?? You have an error, a crash, ... ? If yes, what is the exact error message, ... Give more details.
Then, when you post code, please use the PRE tags to format your code correctly.
Concerning your program, what do you want to achieve by doing this ?
do{
MyDay.display();
}
There is a do without a while condition so it won't compile. Then, you want to print the date an infinite number of time ?

i am very sorry.
there is no error on the program at the moment but what it supposed to do is take input from users enter dates for example if you run it, the output is
12/12/2003 but i want it to accept more than one date for example
12/01/2003
13/12/2003
14/03/2003 and so on.
This is the actual code
<br />
#include "stdafx.h"<br />
<br />
#using <mscorlib.dll><br />
using namespace std;<br />
<br />
class Day{<br />
private:<br />
int day,month,year;
<br />
public:<br />
Day(int,int,int);
~Day();
<br />
void display();<br />
};<br />
<br />
Day::Day(int d,int m,int y){
day=d;month=m;year=y;
<br />
}<br />
<br />
Day::~Day(){}<br />
<br />
<br />
void Day::display(){<br />
std::cout<<day<<'/'<<month<<'/'<<year<<std::endl;
<br />
}<br />
<br />
int main(){<br />
int d,m,y;<br />
std::cout<<"Please Input the date :\n";<br />
std::cin>>d>>m>>y;<br />
Day MyDay(d,m,y);
<br />
MyDay.display();<br />
<br />
}
|
|
|
|
|
Just put a loop in yout main:
int main(){
int d,m,y;
for (int i=0;i<10;i++)
{
std::cout<<"Please Input the date :\n";
std::cin>>d>>m>>y;
Day MyDay(d,m,y);
MyDay.display();
}
}
This will allow you to enter 10 times the date.
|
|
|
|
|
this is what i made up now but it is not working
while(MyDay!=0)<br />
{<br />
cout << Day<br />
}
|
|
|
|
|
the date should be printed say 30 if it is jan,feb,march,may,july, august , oct ,dec then 31 for sept ,april ,june and nov and 28 for feb.

Pete,
if you really expect people to help you, then you should start expressing yourself a little more precise. I don't blame you for your lack of programming skills or understanding of the language because we have all been rookies, but with short phrases like this:
"he date should be printed say 30 if it is jan,feb,march,may,july, august , oct ,dec then 31 for sept ,april ,june and nov and 28 for feb"
you'll probably get no further assistance here. However in additon i would recommend you to read some tutorials about c++ or programming in general.
I hope this was not too harsh...
cheers Tobias

Run in degug mode, then you will see an exact error message, or at least run every line, then you will find what is the problem.

Hello there,
I'm trying to build a couple of projects automatically using a build script. In these projects there are a couple of VS.Net 2005 C++ projects with different project directory (include/library) settings. The reason why I can't just place all these directory settings together is because some libraries conflict with each other.
I'm trying to build these projects in the build script using the "devenv.exe /build ..." command. How can I change the directory settings using the "devenv.exe" command, or is there another way?
Thanks!
~Rafferty

No. It menas, nobody read it that would know the answer, or are too lazy to write it down.
ps: I don't know the answer

I realize that error descriptions have gotten better, but they still need to come a long way. I will post both my error message and code in hopes that someone can help me out with this, because I am lost.

Your class, DataOperations, has a private constructor (ctor), DataOperations(), and a private destructor, dtor, ~DataOperations(). I believe your program requires your ctor and dtor to be public.
|
|
|
|
|
ah ha! working now. thanks a lot. I thought default constructors were public by default.
thanks again!
Thanks,
John

it didn't work? how can i make it plz?
#using<<mscorlib.dll>>
using namespace System;
#using <<system.xml.dll>>
using namespace System::Xml;
int main(int argc, char* argv[])
{
//check for required arguments
if (argc <2)
{
Console::WriteLine("Usage :CppXmlTextReader path");
return -1;
}
String^ path = gcnew String(argv[1]);
try
{
//create the reader...
XmlTextReader^ rdr = gcnew XmlTextReader(path);
//Read nodes
while (rdr->Read())
{
//do something with the data
}
//read nodes
while (rdr->Read())
{
switch (rdr->NodeType)
{
case XmlNodeType::XmlDeclaration:
Console::WriteLine("->XML declaration");
break;
case XmlNodeType:ocument:
Console::WriteLine("->Document node");
break;
case XmlNodeType::Element:
Console::WriteLine("->Element node, name{0}",rdr->Name);
break;
case XmlNodeType::EndElement:

break;
case XmlNodeType::Text:

}
}
}

Try using "int main(array<System::String ^> ^args)" instead of "int main(int argc, char* argv[])"!
|
|
|
|
|
i got the following error:
error c2693: '<':illegal comparison for references to a managed array when i check on arguments,,how can i solve it? how about the constructor?
|
|
|
|
|
// In C++/CLI the "exe" name is not included in the argument array.
// If your path has has spaces, be sure to surround it with quotes.
// Example CppXmlTextReadr "c:\program files\file.xml"
int main(array<System::String ^> ^args)
{
if (args->Length < 1)
{
Console::WriteLine("Usage :CppXmlTextReader path");
return -1;
}
String^ path = args[0];
Console::WriteLine(path);
return 0;
}

Excuse me, Sorry,,but i don't know where to place the path of the XML file,,
when i run my program in the command line i write it? or how?
|
|

If you are talking about running your program from Visual Studio, here is what you do:
1. Right-click on your project.
2. Click on "properties"
3. Under "Configuration Properties", click on "Debugging".
4. On the right of the window, you will find "Command Arguments". Place your arguments there.
Peace
