I'm pretty new to C, just looking to see how to display a image and some text to go along with it so far I can display in the image but cannot display the text at the same time.
This is my source code below
Code:
#include <stdio.h>
#include <gd.h>
int main() {
gdImagePtr gdImage = gdImageCreate( 100, 100 );

I have a project which opens an image in PictureBox1, no problem. But the Public Static Color method at the bottom of the code is not working. I was hoping it would display the average value of the pixels in the image. why it is not working?

I am creating an employee details project, the image is getting stored in the database but i am not able display it in the picture box.

In sql server i have table called emprecordtable and i have the fields eid, rfid, empname, designation, phno, addres, and photo which is the image field and i have given the datatype as image but in the database the image is getting stored as Binary Data.. So, how to display in the picturebox from the database.
I am writing a program to display values from a data file as an image. But I can only get a blue screen. Here is a small program resembling my code. what I have missed? I only changed OnDraw function.
Code:

CColorDisplayDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
if (!pDoc)
return;
CRect rect;

I would like to add an image to this code where the arrows are:
#include <iostream>
#include <cstdio>
#include <cstdlib>
using namespace std;
/*VARIABLES*/
float menuoption;
float minecraftoption;
int mobdetail;
[Code] ....
What is the code for adding an image (btw- I can't use Visual Studio C++ cause it lags so much!)
If code has some errors in it - I had to shorten it because it was 10,000 letters!
I want to create a program using c++ which will accept text from the user and then adds it onto a image of a form in specific locations (if that makes sense?)
and what libraries will be required?
My goal is to have couple of items in the listbox and when highlighting one item a image in the picturebox should appear, and so on for each item in the listbox.I just don't know how to change image depending on selected item in the listbox instantly.Also when i highlight item a text in label should be like in highlighted item in listbox.
View 1 Replies View RelatedUsing C . I have been tasked (for a University assignment) to create a program that will enable a user to upload an image and convert that image into ASCII text using SDL on a Linux system. I've managed to open a window, display an image (non-selected) and convert it into grayscale using
case SDLK_g:
for (int y = 0; y < image->h; y++) {
for (int x = 0; x < image->w; x++) {
Uint32 pixel = pixels[y * image->w + x];
Uint8 r = pixel >> 16 & 0xFF;
Uint8 g = pixel >> 8 & 0xFF;
Uint8 b = pixel & 0xFF;
Uint8 v = (0.212671*r)+(0.715160*g)+(0.072169*B)/>;
pixel = (0xFF << 24) | (v << 16) | (v << 8) | v;
pixels[y * image->w + x] = pixel;
I am absolutely clueless as to how I can get the user to upload an image to the program and then begin the image -> ASCII conversion. I've found seem to be written in C++ or C# to make the conversion I should be using the GetPixelColour command?
I have a very simple application that I want to display counts on a textbox. The problem is that the counter freezes the entire program and it only shows the last count. So I want to count from 0 to 100 incrementally with a delay of 250ms per count and display as it counts on the text box. 0...1...2...3......100 etc
Code:
private void count() {
for (int i = 0; i < 101; i++) {
textBox3.Text = i.ToString();
Thread.Sleep(50);
} }

how to read and display the content of a text file in my console application using C++. The file contains 25 lines and 3 columns.

I'm supposed to read a text file and display it in the output. I have it down except my formatting. I just cannot get it to just skip one line rather than multiple. I know why though because my char has a max of 11 and if I put a character lets say mango, it is going to fill in the rest with white spaces. It's supposed to display like this:
Mango
Strawberry
Grapes
But instead I get something like this
Mango
Melon
Grapes
I am using isspace but it's not working.

I am now making a Dictionary using C++. My goal is to search the word and display the definition of the searched word from the text file. I have a code but it is not working. How can I search a word and display the definition of the word from a text file?

so user wants to find tech..and everything associated with it.
so program search for tech, when it does it then display the whole row.

{string letters;// search word would be store here
string row; ??stores entire row as string

I want to display data from text file in list view and in tree view root will be file name, but i dont know how to do it, the problem is with displaying text file data in list view, i don't know anything about that. text file data is very simple. It is just a square matrix of double values like:
21.06 34.06 5.0
12.78 45.25 6.9
12.89 45.98 5.5
in list view i want to display it.
I am trying to display some data in text format on a dialog and I am using a CString to do it. Below is how I coded it.
Code:
CString outputStr;
CString auxStr;
// Add header
outputStr.Format("");
auxStr.Format("%-7s%-20s%-7s%-20s%s
[Code] .....
But the output rows are not aligned as shown in the attached picture. There a two problems.
1. Data rows don't align with the header row.
2. When the first element of a row changes to two digits, the other elements are shifted.
According to MSDN [URL] ...., CString::Format() works the same way as printf(). I wrote a small program using printf() to do the same thing, and the output in the console are perfectly aligned.
What have I missed when doing the display in GUI?
Im trying to compare the image of a button to another image in Visual Studio like so...
//variables
Image active = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\active.png");
Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");
[Code]...
btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))
I do have a feeling ive done something wrong here (Yes im a noob /> )
Variable active, is the same image as the buttons default (Well should be)
I am writing a piece of code that requires me to display the last 1000 lines from a multiple text files (log files). FYI, I am running on Linux and using g++.
I have a log file from which - if it contains more than 1000 lines, I need to display the last 1000 lines. However, the log file could get rotated. So, in case where the current log file contains less than 1000 lines, I have to go to older log file and display the remaining. For e.g., if log got rotated and new log file contains 20 lines, I have to display the 980 lines from old log file + 20 from current log files.
What is the best way to do this? Even an outline algorithm will work.
I created class called students which suppose to store students names of in array but when I call the display function it display only the first name. but I want it to display names depending on the array size.
