C# :: Best Way To Store And Load Image Into Access Database?
Dec 12, 2014I have:
An Access database in which the picture right now is saved by its directory, together with other field like title, publisher, developer,..
Visual Studio form in which a load button gets that directory as text
Details button that reads the ID of a selected item (I have a list of games) and displays the corresponding picture by reading the directory
The problem right now is that once someone else opens the program on his/her computer, the directory changes, making the whole thing useless.
Is there a way to get around this problem? The books I've been reading don't really adress this.
Directory is a string in class 'Game'; it's short text in the database
private void buttonFoto_Click(object sender, EventArgs e) {
LoadNewFile();
}
private void LoadNewFile() {
OpenFileDialog ofd = new OpenFileDialog();

C :: Fahrenheit To Celsius Scale Converter
May 28, 2014One of the questions requires writing up a code, that converts Fahrenheit scale to Celsius scale.
The relation between temperature in ◦ C and ◦F is given by the formula:
◦C = 5/9 . ( ◦F - 32 )
Write a program that prints a table (just two columns without any borders) with temperature in ◦F and ◦C for temperatures between 0 and 300 ◦F in steps of 20◦. Compile and run your program. I wanted to approach this problem via arrays and for loops, and I wrote up this
Code:
#include<stdlib.h>
#include<stdio.h>
int main() {
// begin main()
// units
double[] celsius = new double[ 16 ];
double[] fahrenheit = new double[ 16 ];
[Code] ....
Now when I'm trying to compile that, the compailer throws an error which makes absolutely no sense to me.
Code:
fahrenheitCelsius.c: In function ‘main’:
fahrenheitCelsius.c:18:9: error: expected identifier or ‘(’ before ‘[’ token
double[] celsius = new double[ 16 ];

C# :: Compare The Image Of A Button To Another Image In Visual Studio
Jul 3, 2014Im 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)

Feb 1, 2015I am working on pset4 in the CS50 online coarse. The goal is to resize a bmp image. I have it working except adding the padding back to new resized image.

If the factor I resize the image by works out to have 3 bites of padding it works perfect and if the image has no padding it works perfectly I need a fresh pair of eyes.

C :: Editing Image In PPM Format
Mar 10, 2014I'm trying to edit an image by multiplying the red component of each pixel by 10 and leaving the other components (green and blue) untouched. I'm not really sure how I'm supposed to edit the pixels one by one. I have this so far. I think there is something wrong with my ppm header as well. Is there a way to make a ppm header without specifying the bounds so that it conforms to the image you are putting in?
