when <b>1</b> is given as input following program shows <b>b</b> as output why is that so I know that 1 given to char is manipulated differently but how it's being manipulated please explain.
#include <conio.h>
#include <iostream>
using namespace std;
int main()
{
char ch;
cout<<"enter ch ";
cin>>ch;
ch=ch*2;
cout<<ch;
getch();
return 0;
}

I try to invoke oracle pro*c in C++/CLI project. This is my sample code.
#include "stdafx.h"
using namespace System;
using namespace System::IO;
using namespace System::Diagnostics;
void call_Process (ProcessStartInfo^ info) {
try {
Process^ exeP = Process::Start(info);
StreamReader^ reader = exeP->StandardOutput;
String^ result = reader->ReadToEnd();
Console::Write(result);
Console::ReadLine();
}
catch(Exception^ e) {
Console::WriteLine(e->Message);
Console::ReadLine();
}
}
int main(array<system::string ^=""> ^args)
{
ProcessStartInfo^ pStartInfo = gcnew ProcessStartInfo();
pStartInfo->UseShellExecute = false;
pStartInfo->RedirectStandardOutput = true;
pStartInfo->WindowStyle = ProcessWindowStyle::Hidden;
pStartInfo->FileName = "\"C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\VC\\vcvarsall.bat\"";
pStartInfo->Arguments = "x64";
call_Process(pStartInfo);
pStartInfo->FileName = "proc.exe";
pStartInfo->Arguments = "oracle_connect.pc";
call_Process(pStartInfo);
pStartInfo->FileName = "\"C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\VC\\bin\\amd64\\cl.exe\"";
String^ arg1 = " /I C:\\app\\Administrator\\product\\11.2.0\\dbhome_1\\precomp\\public";
String^ arg2 = " /link C:\\app\\Administrator\\product\\11.2.0\\dbhome_1\\precomp\\LIB\\ORASQL11.LIB";
pStartInfo->Arguments = arg1 + " oracle_connect.c" + arg2;
call_Process(pStartInfo); // throws exception.
pStartInfo->FileName = "oracle_connect.exe";
call_Process(pStartInfo);
return 0;
}
When I type in ,call vcvarsall.bat in command prompt window myself and run this codes, it works. No exception. But when I run this code in another command prompt window without calling vcvarsall.bat, it throws exception. Calling vcvarsall.bat with Process::Start method doesn't work!
Pls, advise me how to call vcvarsall.bat with Process::Start method. Thanks in advance.
Best Regards!

And what exception is it that it is throwing?

The source can't include stdio.h file. When vcvarsall.bat executed in command prompt window in advanced and environment set, #include stdio.h throws no exception.

You cannot execute these processes independently in this way. vcvarsall.bat needs to be called in the same environment that the compiler will be called. You need to create a new batch file that contains all the commands that you wish to run, and execute that batch file.

already tried #pragma make public (mynativestruct)
Here is my c++-cli code
ClassLibraryAT::Class1^ matClass = gcnew ClassLibraryAT::Class1() ;
matClass->M_AT(&cparams,&input,&numcontacts,&contact,&ecdata);
the 'input' struct in the argument list is comprised of ints doubles, stuff like that. Not a managed struct. It's saying the candidate function M_AT is not accessible. How do I resolve this? thanks, sb

Make sure that M_AT is a public method.

thanks Richard. It is a public method and shows up in the intellisense.

I'm afraid that tells us nothing; try looking at the actual class definition or documentation.

hi Developers,
I am trying to get the result of this code
printf( "sqrt(36.0) = %f", sqrt(36.0) );
The mystry is that, If i have include math.h file, than I am getting proper result, bu I haven't, I am getting the result 0.000000
can you please help me out
Thanks

I just tried without including math.h and it works fine. Try seeing what the actual definition of sqrt is when you have not included the header.

I developed a program to convert celcius to kelvin and one to convert kelvin to Fahrenheit...now what I want to do is convert celcius to Fahrenheit reusing my programs with IO stream redirection,with input and output on batch files...clear?

|

Why not just do everything in one single program using a class to do the conversions?

never mind its fine thanks

The answer given in that question is correct. There is no C++ keyword equivalent to using() from C# because C++/CLI has deterministic finalization. When the object goes out of scope and there are no more references, it will be disposed.

Hi Developers,
I am trying to run this chunk of code.
struct value
{
int bit1:1;
int bit3:4;
int bit4:4;
}bit;
printf("%d\n", sizeof(bit));
I am getting value "4". I am running this program in 32 bit machine using Microsoft Visual C++ complier.
Can you please clarify about the result.
