I am a novice in programming and i need Your advice, please.
I was tasked with writing a programm that will be counting number of items needed according to length of a track. This track we need to draw by ourselves, but I don't want to make this application full screen, so I need a Zooming function and for a life of me I can't get how should i do it.
Please help!
And here's the code.

Again, I am asking a question about a USB Printer. This time however, the issue is more on the programming end of the spectrum.
I have a windows forms application in which I generate a receipt, which is then supposed to be sent to the printer. The Following things work: Generating the receipt, Sending the data to the printer.
The data however is only an empty strip of paper. I have the feeling that the Software is ignoring the Panel contents and just sends the empty panel to the printer.
The Sourcecode is as follows:
namespace MakeyMakey

public partial class Form1 : Form
{
public void Gridsettings()
{
GVReceipt.ScrollBars = ScrollBars.None;

I have also included two images, one shows what the receipt looks like, the other what the print preview generated.
I'd highy appreciate any help on that topic.
I have this code and when I run it, it has moved but has two label display on screen, one is no move, one has move
public partial class Form1: Form
{
int x = 25, y = 1;
public Form1()
{
InitializeComponent();
}
private void timer1_Tick(object sender, EventArgs e)
{
label1.SetBounds(x, y, 255, 255);
x++;
if (x >= 800)
{
x = 1;
}
}
private void Form1_Load(object sender, EventArgs e)
{
label1.Text = "hii";
label1.Font = new Font(" ", 22, FontStyle.Bold);
timer1.Interval = 10;
timer1.Start();
}
}
You have to add one more label from toolbox to form. In timer set new label's bounds also like this:
int x = 25, y = 1;
public Form1()
{
InitializeComponent();
}
private void timer1_Tick_1(object sender, EventArgs e)
{
label1.SetBounds(x, y, 255, 255);
label2.SetBounds(x, 100, 255, 255);
x++;
if (x >= 800)
{
x = 1;
}
}
private void Form1_Load_1(object sender, EventArgs e)
{
label1.Text = "hii";
label1.Font = new Font(" ", 22, FontStyle.Bold);
label2.Text = "hii2";
label2.Font = new Font(" ", 22, FontStyle.Bold);
timer1.Interval = 10;
timer1.Start();
}
I have this code that draws a rectangle using the ShapeClass.cs. But I want to update the Rectangle parameters using a button event in the mainform. How do I do that?

You can create other class which contain both PaintEventArgs and your params. Ex:
public class DrawArgs
{
// parameter which you can modify base on your logic
public int width;
public int height;
public int x;
public int y;
//your paint event
public PaintEventArgs e;
}
And modify your ShapeClass.paintRectangle() method:
public class ShapeClass
{
public void paintRectangle(DrawArgs drawArgs)
{
//w1 = Convert.ToDouble((Convert.ToInt32(f1.ShapeWidth()) * 96) / 25.4);
//h1 = Convert.ToDouble((Convert.ToInt32(f1.ShapeHeight()) * 96) / 25.4);
//x = ((484 / 2) - (Convert.ToInt32(w1) / 2));
//y = ((484 / 2) - (Convert.ToInt32(h1) / 2));
// get your params
var x = drawArgs.x;
var y = drawArgs.y;
var w1 = drawArgs.width;
var h1 = drawArgs.height;
Pen red = new Pen(Color.Red, 3);
Rectangle rect = new Rectangle(x, y, Convert.ToInt32(w1), Convert.ToInt32(h1));
drawArgs.e.Graphics.DrawRectangle(red, rect);
}
}
And you can call it from paintRect method():
public void paintRect(object sender, PaintEventArgs e)
{
ShapeClass s = new ShapeClass();
var drawArg = new DrawArgs
{
e = e,
// and add your params here
x = something,
y = something,
///.....
};
s.paintRectangle(drawArg);
}
P/S: it is just an example. You can modify the DrawArgs class base on your logic
Add a anothe function to change the parameters.
For example:
void UpdateParameters()
{
ChangeParameters();
}
Give you another suggestion: You can edit this question to add Codes.
I am currently working on a platformer in C#,VS 2015
The problem i have encountered is:when i press the left/right arrow,the background moves behind the player in the opposite direction,and this happens using a timer(which cannot be set to a value lower than 1 milisecond).
Because the timer is limited to 1 milisecond,the background moves laggy,and i would like to solve this :D
Here is the code

}
}
private void pictureBox2_Paint(object sender, PaintEventArgs e)
{
Pen p = new Pen(Color.Red);

You should be able to simply multiply by factors, i.e. smallBox.Width/largeBox.Width and smallBox.Height/largeBox.Height. Multiply the coordinates for the larger box by those factors and it will give you coordinates for the smaller box.
Edit:
This is what my code looks like:
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Forms;
namespace PBoxes
{
public partial class Form1 : Form
{
private float xFactor, yFactor;
List<PointF> points = new List<PointF>();
public Form1()
{
InitializeComponent();
xFactor = (float)pictureBox2.Width / pictureBox1.Width;
yFactor = (float)pictureBox2.Height / pictureBox1.Height;
}
private void pictureBox1_MouseClick(object sender, MouseEventArgs e)
{
points.Add(new PointF(e.X * xFactor, e.Y * yFactor));
pictureBox2.Invalidate();
}
private void pictureBox2_Paint(object sender, PaintEventArgs e)
{
foreach (PointF pt in points)
{
e.Graphics.FillEllipse(Brushes.Red, pt.X, pt.Y, 3f, 3f);
}
}
private void pictureBox_SizeChanged(object sender, EventArgs e)
{
xFactor = (float)pictureBox2.Width / pictureBox1.Width;
yFactor = (float)pictureBox2.Height / pictureBox1.Height;
}
}
}
