I am using Windows XP SP II and Visual Studio 2008. I've created a little program that I'd like to run when the computer boots. Here is the code:
// dummy1.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
#include "Windows.h"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
Sleep(5000);
ifstream ins;
ins.open("HelloWorld.txt");
string textToDisplay, outFileName;
getline(ins, outFileName);
getline(ins, textToDisplay);
ins.close();
ofstream outs;
outs.open(outFileName.c_str());
outs << "hello\n";
outs << textToDisplay << endl;
outs.close();
while (true)
{
cout << "hello\n";
cout << textToDisplay << endl;
Sleep(1000);
}
return 0;
}HelloWorld.txt is a little two line text file:
HelloWorldOutput.txt
Hello World!I have put the dummy1.exe file into the Windows registry so that it runs at startup time. i get the following results:
hello
hello
hello
etc...No new file is created and "Hello World!" is not displayed, so it looks like the input file was not successfully opened or read from. However, when I run the program normally (i.e. double click it after the computer has already started up, it runs correctly. The new file is created and the output to the screen is:
hello
Hello World!
hello
Hello World!
hello
Hello World!
etc...Is there some type of permissions problem? Can a program not use ifstream or ofstream in a Startup program or read or write files or something? If so, is there a way to fix that?
Thanks.
