C++ :: Print Custom Area Of Screen - Save As Image File

Sep 9, 2014

I am trying to automatically(periodically) print screen a custom area of the screen, save it as an image file (the image will have the same format always), and then use OCR to get the text in the image as usable string variables. Is this doable? I was looking into tesseract OCR but I find it a bit unclear.

C++ :: Scanning A Header File To Save Image Data

Jun 11, 2013

I'm trying to read from a header file to take the image dimensions and other variables but I don't understand how to iterate through the "key" so it saves each line.

This is what the header file will always look like:

!INTERFILE :=
!imaging modality := nucmed
!version of keys := 3.3
;
!GENERAL DATA :=

[Code].....

Ideally it would just skip the keys that aren't wanted and keep moving through the lines. Should there be a for loop for the key (and if so, how does that work with pointers?) or should this method just be scratched...

C++ :: Convert List Of Binary Numbers From A File Into Decimal And Print To Screen

Sep 23, 2014

I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:

3
10110101
11111111
10101010

The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.

I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....

Managed C++ And C++/CLI :: App That Shows Pixelated Picture In Window - Reference Image On Screen?

Jan 11, 2014

I am developing an app that shows a pixelated picture in a window. I am trying to capture the image, which is composed of a number of tiles processed from a mother image, but I am having difficulty since I can't reference the image on the screen. I have placed a rectangle around the image and my understanding is that I have get the window handle for the rectangle in order to save the Image as a jpg file. In the literature there is something about a Device Context and a window handle but my compiler throws out HWND and I don't really understand the device context. I am using Windows Forms, not native code.

Visual C++ :: Unable To Save File Using Cfiledialog Save As In MFC

Nov 5, 2013

I am trying to develop a GUI using MFC, but I am having trouble using CFiledialog to save a file. The problem is, the file is not getting saved to the folder when I use the CFiledialog. Below is the code I am using.

Code:

CString szFilter = "XNRep Files (*.xnrep)|*.xnrep||";
CString s = "xnrep";
CString t = "";
CFileDialog fileDlg(FALSE, s, t, NULL, szFilter);
if(fileDlg.DoModal() == IDOK)
{
std::ofstream file;

After the file dialog opens up, I enter the name of the file and select OK button. But the file does not show up in the directory I am saving to.

C :: Print The Inverse Number On Screen

Dec 25, 2014

Print the inverse number. Ex: 2178*4=8712

Write down a program which can satisfy the prerequisite and print out the screen.

The answer is:

Code:
void inverse2 ()
{
int i,j;
for (i=1000;i<=9999;i++)
for (j=1;j<=9;j++)
if (i*j==inverse (i))
printf("%5d%2d",i,j);
}

I can't understand the double for loop.

for (i=1000;i<=9999;i++)
for (j=1;j<=9;j++)

And The meaning for

i*j==inverse (i)

C :: Printf Doesn't Print On Screen

May 23, 2013

This code runs. However, when I run it, the text from printf doesn't appear until after I type in the two numbers.

I use Wascana, will it run correctly on other compilers?

Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main() {
fflush(stdout);

[Code].....

And this is how it turns out on the screen:

Code:

6
3

What size is the die:

how many dice to roll:

Numbers are 3d6
Rolling die no.1...
RolledDie: 4 DieTotal: 4
Rolling die no.2...
RolledDie: 5 DieTotal: 9
Rolling die no.3...
RolledDie: 5 DieTotal: 14

The total is: 14

C++ :: Check If A Number Is Odd Or Even And Print It To The Screen

Mar 8, 2013

My objective is to check to see if a number is odd or even and print it to the screen just to make sure its working correctly.

The data file contains:
138
402 2 485
9
43
98 805
58
421
948 7 97
48
67
35
42
948
579 39 12
700 20 500 210
98

I can get the numbers to print fine using:

fstream infile1(argv[1]);
if(!infile1.is_open())
cout << "Could not open file";
else {
char listNum;
while(infile1.get(listNum))
cout << listNum;
}

However, when I check for odd or even numbers it will check each and every number.

printed like this (partial list):
1 is odd 3 is odd 8 is even
9 is odd

But it should print:
138 is even
9 is odd

I tried using getline, but it keeps giving me the errors:
invalid conversion from 'void*' to 'char**'
invalid conversion from 'char' to 'size_t*'
too few arguments to function 'ssize_t getline(char**, size_t*, FILE*)'

Here is the getline code, what am I doing wrong? I have tried switching things around, adding things. Just nothing works.

ifstream infile1(argv[1]);
if(!infile1.is_open())
cout << "Could not open file";
else {
char listNum;
getline(infile1, listNum);
cout << listNum;
}
