C :: Opening A File For Read Only On Screen

Apr 4, 2013

How to open a file and just print what is in that file on the screen. I though maybe I had the directory wrong but putting G: or G: give me the same result. When I select 1 it just goes to the next line and doesn't print anything.

Code:
int getchoice(void)
{
int num;
int choice;
FILE* outputfile;

Visual C++ :: Internet Explorer Displays Blank Page When Opening Local File While Screen Is Off?

Apr 28, 2015

I'm making a small MFC module that should generate a report (formatted using HTML) and then display it for a user on schedule at 8:30 AM every day. Pretty straightforward stuff.

I compose my report and then save it as a local HTML file in the CSIDL_APPDATA folder. I then use the following calls to display it using the default web browser (Internet Explorer in this case):

Code:
//Error checks are omitted for brevity
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
ShellExecute(NULL, NULL, strSaveFileTo, NULL, NULL, SW_SHOWNORMAL);

This module is run on schedule from the Task Scheduler. (The task is set up to run when a user is logged on, which is all the time for that PC. It is never turned off, put to sleep, etc. That computer has only one user that is never logged off either.)

This works perfectly fine when I test it by setting the task a minute or so in the future. But when the actual task is supposed to run at 8:30 AM, when the user wakes the screen all they see is a blank Internet Explorer page. (Note that if someone refreshes that page by hitting F5, only then my report is shown on the screen.)

So I started looking into it:

1) I checked that the file is properly saved (before calling ShellExecute) by reading it back and by comparing it with the original HTML markup that I saved earlier. It's all correct there.

2) I then checked the power saving options. That computer is set up to show screensaver after 5 minutes and to turn off screen after 25 minutes.

3) The web browser that causes this issue is IE version 11, with the latest updates installed. The operating system is Windows 7 Professional.

And why is IE showing a blank page only when computer is running unattended?

C :: Opening File - Read / Write

Aug 5, 2013

this is my read/write functions based the read from the last post! then went nuts with it! used the %19s%*s on the write to the file, solved all the probs on the read side! but any refining on this would be great. This is another program that i started with the forums, and started going my own direction!

Code:

void WriteAccount(int account,char *a[])
{
FILE *fptr;
char Memo[20];
char buff[20];
double Amount;
struct tm *sTm;
}

[code]....

the a[] is a string array with bank account names, and Account is the number on the menu based list.

C/C++ :: Read From Dat File And Produce Output On Screen - Error C2664

Feb 5, 2014

My professor wants me to write a program that will read from a dat file, and produce an output on the screen based on the file. I don't understand why I am getting this error. I suspect it has something to do with the number of characters I've told it to read.

#include<iostream>
#include<iomanip>
#include<fstream>
#include<assert.h>
#include<string>
using namespace std;
using namespace System;
struct TStudent {
string month[10];

I noticed I had a 2 beside girl, after I removed it, it still didn't fix my problem.

C++ :: Error Opening File In Input

Nov 8, 2014

ofstream infile;
infile.open("Input.txt");
if(infile.fail()) {
cout << "Error Opening File in Input" << endl;
system("pause");
exit(1);
}

So I'm trying to see if it fails, but if i change "Input" name would the computer just create a new file name of it for example if i change "Input" to "asdf" the computer is just going to create "asdf" how do i fix it.

C Sharp :: Opening A File By Using The Extension?

Apr 24, 2013

The code below is used to return a file path.

 private string BrowseJournalFile(string startRelativePath)
        {
            string str = "Journal files (*.log)|*.log|All files (*.*)|*.*";
            return PathTools.BrowseFile(startRelativePath, str, this.RootPath);    
        }

So once I click browse I get something like "E:New Files" But there is this .log file in this folder which I want to automatically store in this path.

Right now I have to click on this .log file and then select open. Is there a way I can directly load the file.I have been trying to use the FileStream but no luck.

C/C++ :: Program That Read A Number From Keyboard And Print Separated Digits To Screen

Feb 18, 2015

Basically this is what i need to do. Write a program that reads a number from the keyboard, separates it into its individual digits and prints the digits to screen, each on its own line followed by the same number of stars as itself.

For example, if the number is 2339 the program should print

9 *********
3 ***
3 ***
2 **

So far i have managed to separate the number and have them on different lines, but how to implement the stars onto each line with the number!

My code so far:

int main() {
int n;
printf("number? ");
scanf("%d", &n);
while (n > 0) {
printf("
%d

C/C++ :: Error Handling For File Opening And Reading

Apr 23, 2014

I am writing to write a program and performs the following tasks

- Reading a file (txt file contains some temperature values)
- Display the temperature values (contents of the file)
- Calculating the average of the temperature values in the file.
- finds the maximum and minim value of temperature in the file.

The program is user interactive and waits for the user input and process according to his input (choice)

I have managed to complete the program and covered all the expect except the error handling for file opening and reading, although I have managed to do it for the part one part (i.e for the choice == 1)

I can repeat it for the other choices (i.e for 2, 3 ) but I do not want to repeat the code and do it in a different function or do it once for all. While making an attempt I can not handle the rest of the program and all the program turns into a mess.

#include <iostream>
#include <fstream>
#include <iomanip>
int menu();
int myChoice(char);
char inputValidating();

[Code] .....

Need Error handling for file opening and Reading that is used once, So far I have managed to do it for choice 1

C :: Read A Line From Screen / Takes ASCII Values From Entered Text And Edit It

May 10, 2013

This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.

compiled with -std=c99.

Code:
#include <stdio.h>
int main(){
int maxsize;
printf("How long is your message?

C++ :: Incorporate Array Of Structures To Read User Input Then Reprint That Information To Screen

Nov 18, 2014

I have to create a program that incorporates an array of structures in order to simply read input from the user and then reprint that information to the screen. This is a fairly simple problem, but the issue is that the professor requires that we solve it in a very specific way.

I must have three functions in total: one to receive input from the user, one to print the received values, and of course the main function which calls the other two. Also, the input and output functions must be defined using the following prototypes:

void inputData(Component C1);
void printData(Component *C1);

Where Component is a structure defined above as:

typedef struct// Component {
float cost;
int code;
char name[30];

[Code] ....

I know that this problem could be easily solved by simply passing the entire 'comp' array to the inputData function, or passing a pointer to it, or having it return a pointer, but I am not allowed to do any of these things. I must use the function as defined by the prototype.
