I have plotted a graph in c#. How can I move the graph vertically up and down when a button is pressed.
private void button1_Click(object sender, EventArgs e)
{
chart1.Series[0].Points.Clear();
if (button1.Enabled == true)
{
for (int i = 0; i < 20; i++)
chart1.Series[0].Points.AddXY(i, Y1scale(i) + 1);
}
}
this is the code I have coded. But only on the first click it works. Further I want to move the graph continuously like in an oscilloscope without jumping from 1 y unit to another
I use a counter and each mouse click is counted and y values are shifted adding count value to the existing y value.
public Form1()
{
InitializeComponent();
}
double ch1_count_up=0;
double ch1_count_down = 0;
private void button1_Click(object sender, EventArgs e)
{
if(radioButton1.Checked==true)
{
ch1_count_up++;
chart1.Series[0].Points.Clear();
for (int i = -20; i < 20; i++)
chart1.Series[0].Points.AddXY(i, Y1scale(i) + (ch1_count_up / 10) - (ch1_count_down / 10));
}

I have a class assignment to move a picturebox randomly across the form. Once you click on the picturebox, it is supposed to scream and change the picture then change it back to the original picture. When you click again, it is supposed to go faster. I have it working up to the point of making it go faster. Here is my code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
tm1.Interval = 1000;
tm1.Tick += new EventHandler(tm_Tick);
}
Timer tm1 = new Timer();
int X = 0;
int Y = 0;
private void pictureBox1_Click(object sender, EventArgs e)
{
if (timer1.Enabled)
{
timer1.Stop();
pictureBox1.Image = Properties.Resources.Mimikyu;
Application.DoEvents();
pictureBox1.WaitOnLoad = true;
System.Threading.Thread.Sleep(10);
SoundPlayer sp = new SoundPlayer(Properties.Resources.screa);
sp.PlaySync();
pictureBox1.Image = Properties.Resources.Evee;
}
else
timer1.Start();
}
private void tm_Tick(object sender, EventArgs e)
{
int X = ((int)(new Random().Next(0, 1000)));
int Y = ((int)(new Random().Next(0, 500)));
if (X > 1025 - pictureBox1.Width)
{
X = 1025 - pictureBox1.Width;
}
if (Y > 545 - pictureBox1.Height)
{
Y = 545 - pictureBox1.Height;
}
pictureBox1.Location = new Point(X, Y);
}
}
}
Point me to where I need to go to get the interval to move faster and faster after each click Thank you.
decreasing the tm1.Interval should do it
...
else
if (tm1.Interval>10){tm1.Interval -= 10;}
timer1.Start();
I'm working on a project where I work with two graphs, and on the lower graph if I see the maximum of the x-axis (24) but on the upper graph no. How can I make it appear up on 24? I am using the chart windows in visual studio, the default chart in windows forms
Chart image
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
chart1.ChartAreas[0].AxisX.Minimum = 0;
for (int i = 0; i <= 24; i++)
{
chart1.Series[0].Points.AddXY(i,1+i);
}
}
}
Change your code to (more information here):
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
// Maximum/Minimum controls the length of the Axis
chart1.ChartAreas[0].AxisX.Maximum = 30;
chart1.ChartAreas[0].AxisX.Minimum = 0;
chart1.ChartAreas[0].AxisY.Maximum = 30;
chart1.ChartAreas[0].AxisY.Minimum = 0;
// Interval controls the interval between values on the chart
chart1.ChartAreas[0].AxisX.Interval = 1;
chart1.ChartAreas[0].AxisY.Interval = 1;
}
private void button1_Click(object sender, EventArgs e)
{
chart1.ChartAreas[0].AxisX.Minimum = 0;
for (int i = 0; i <= 24; i++)
{
chart1.Series[0].Points.AddXY(i, 1 + i);
}
}
}

I have been trying to code this for a while and after a couple of weeks of searching the web for an answer I decided to ask
All I want to do is gradually resize pictureBox1 to a set limit from a variable starter value when the mouse hovers over it, the furthest I got was using a forloop which made it instantly change size. I would like it to also change height and width at the same time (pictureBox1 will be a square and i just want it to be a bigger square with a bit of smooth movement)
Also I need it to gradually change back to the original size once the mouse moves off of pictureBox1.
I have been toying about with a couple of solutions found on websites but none seem to work properly, also you might need to know that I have two forms involved in this code; Form1 and frmMenu and because of a mass amount of errors I commented out the bottom two methods.
I do not get any errors but it just doesn't work.
public partial class frmMenu : Form
{
//private int size = 100;
public Timer timer1;
public frmMenu()
{
InitializeComponent();
pictureBox1.MouseEnter += new EventHandler(pictureBox1_MouseEnter);
//pictureBox1.MouseLeave += new EventHandler(pictureBox1_MouseLeave);
}
private string frmMenu_Load
{
set
{
timer1.Interval = 1;
}
}
private void pictureBox1_MouseEnter(object sender, EventArgs e)
{
//for (int i = 140; i > size; size++)
//{
//}
{
timer1.Interval = 1;
}
timer1.Enabled = true;
if (pictureBox1.Height <= 140)
{
pictureBox1.Size = new Size(pictureBox1.Size.Width, pictureBox1.Size.Height + 1);
}
else
{
timer1.Enabled = false;
}
}
// private void pictureBox1_MouseLeave(object sender, EventArgs e)
// {
// if (size > 100)
// for (int i = size; i > 100; i--)
// {
// size = i;
// }
// pictureBox1.Height = pictureBox1.Width = size;
// }
// private void pictureBox1_Click(object sender, EventArgs e)
// {
// var Form1 = new Form1();
// Form1.Show();
// var Menu = new frmMenu();
// Menu.Close();
// }
}
This is my first time asking so sorry if I haven't given enough information ^.^
Try this code:
using System;
using System.Drawing;
using System.Windows.Forms;
namespace Test
{
public partial class Form1 : Form
{
bool mouseHover;
int width;
int height;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
timer1.Interval = 25;
timer1.Tick += timer1_Tick;
width = pictureBox1.Width;
height = pictureBox1.Height;
timer1.Start();
}
void timer1_Tick(object sender, EventArgs e)
{
if (mouseHover)
{
pictureBox1.Width += (pictureBox1.Width < 100) ? 5 : 0;
pictureBox1.Height += (pictureBox1.Height < 100) ? 5 : 0;
}
else
{
pictureBox1.Width += (pictureBox1.Width > width) ? -5 : 0;
pictureBox1.Height += (pictureBox1.Height > height) ? -5 : 0;
}
}
private void pictureBox1_MouseEnter(object sender, EventArgs e)
{
mouseHover = true;
}
private void pictureBox1_MouseLeave(object sender, EventArgs e)
{
mouseHover = false;
}
}
}
You can adjust the interval to how you like it, but increasing at 5 pixels horizontally/vertically every 25 milliseconds is pretty smooth. You need to set the initial height and width so you can go back to that size after the mouse leaves the picture box. I use the null coalescing operator so you don't have to stop the timer. As long as the condition on the left side of the ? is true, it will evaluate to the value on the left side of the :. When the condition is false, it evaluates to the right side of the :.
I have a small program that hold 4 button in a 2D Array what I want to do is display its 'X' and 'Y' coordinates of the Array in a message box (when clicked)
I have tried a number of ways some don't work and some work but I cant get it to show the 'X' and 'Y' values
The image below shows what I have so far:
And This is the code i have come up with:
namespace _2DArray
{
public partial class Form1 : Form
{
private Button[,] b;
public Form1()
{
InitializeComponent();
b = new Button[2, 2];
b = new Button[,] { {button1,button2 },
{button3, button4}};
}
private void Form1_Load(object sender, EventArgs e)
{
foreach (Button bt in b)
{
bt.Click += new System.EventHandler(this.ClickedButton);
}
}
private void ClickedButton(object sender, EventArgs e)
{
Button s = (Button)sender;
MessageBox.Show("you have clicked button:" + s);
}
}
}
Here is the answer to your question if i read it right. You are trying to get the X and Y coordinates of the button right?
Here is the code for a button click:
private void button2_Click(object sender, EventArgs e)
{
MessageBox.Show(button1.Location.ToString());
}
try assigning some sort of pointer like give name of the button to keep track of it coordinates
private void Form1_Load(object sender, EventArgs e)
{
for (int i = 0; i < 2; i++)
{
for (int j = 0; j < 2; j++)
{
b[i, j].Click += new System.EventHandler(this.ClickedButton);
b[i, j].Name =i+" "+j;
}
}
}
private void ClickedButton(object sender, EventArgs e)
{
Button s = (Button)sender;
MessageBox.Show("you have clicked button:" + s.Name);
}
Use this code
private void Form1_Load(object sender, EventArgs e) {
for (int x = 0; x < 2; x++) {
for (int y = 0; x < 2; y++) {
b[x, y].Tag = new Point(x, y);
b[x, y].Click += new System.EventHandler(this.ClickedButton);
}
}
}
private void ClickedButton(object sender, EventArgs e) {
Button s = (Button) sender;
MessageBox.Show("you have clicked button:" + s.Tag.ToString());
}
then clicking on button1 will show the message "you have clicked button:{X = 0, Y = 0}" etc
Tag is a property that each control has, it's description is "User-defined data associated with the object" so you can set it to whatever object you like.
I know this is probably a bit late for the op but hopefully it will help someone else.
I have a Multiline richtextbox control into which i want to integrate the feature of adding a line number. i have considered many approaches
Add a label and updating the line numbers as the line count changes
Add a picturebox along with to draw string on it.
Add another textbox along with and show line numbers on it
Add listbox along and display line numbers in it.
I got two doubts.
The richtextbox which i'm using is a custom made control and derieves from RichTextBox class. How can i add multiple controls to it.
What is the best approach to show line numbers for the multiline text in c#
My own example. All is fine, but wordwrap must be disabled :(
int maxLC = 1; //maxLineCount - should be public
private void rTB_KeyUp(object sender, KeyEventArgs e)
{
int linecount = rTB.GetLineFromCharIndex( rTB.TextLength ) + 1;
if (linecount != maxLC)
{
tB_line.Clear();
for (int i = 1; i < linecount+1; i++)
{
tB_line.AppendText(Convert.ToString(i) + "\n");
}
maxLC = linecount;
}
}
where rTB is my richtextbox and tB is textBox next to rTB
J.T. jr
this code helped me thank you, needed to convert visual basic but could:
Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
Dim maxlc As Integer = 1
Dim linecount As Integer = TextBox1.GetLineFromCharIndex(TextBox1.Height) + 1
If linecount <> maxlc Then
TextBox2.Clear()
For i = 0 To linecount - 1 Step 1
TextBox2.AppendText(Convert.ToString(i) + vbNewLine)
Next i
maxlc = linecount
End If
End Sub
public int getWidth()
{
int w = 25;
// get total lines of richTextBox1
int line = richTextBox1.Lines.Length;
if (line <= 99)
{
w = 20 + (int)richTextBox1.Font.Size;
}
else if (line <= 999)
{
w = 30 + (int)richTextBox1.Font.Size;
}
else
{
w = 50 + (int)richTextBox1.Font.Size;
}
return w;
}
public void AddLineNumbers()
{
// create & set Point pt to (0,0)
Point pt = new Point(0, 0);
// get First Index & First Line from richTextBox1
int First_Index = richTextBox1.GetCharIndexFromPosition(pt);
int First_Line = richTextBox1.GetLineFromCharIndex(First_Index);
// set X & Y coordinates of Point pt to ClientRectangle Width & Height respectively
pt.X = ClientRectangle.Width;
pt.Y = ClientRectangle.Height;
// get Last Index & Last Line from richTextBox1
int Last_Index = richTextBox1.GetCharIndexFromPosition(pt);
int Last_Line = richTextBox1.GetLineFromCharIndex(Last_Index);
// set Center alignment to LineNumberTextBox
LineNumberTextBox.SelectionAlignment = HorizontalAlignment.Center;
// set LineNumberTextBox text to null & width to getWidth() function value
LineNumberTextBox.Text = "";
LineNumberTextBox.Width = getWidth();
// now add each line number to LineNumberTextBox upto last line
for (int i = First_Line; i <= Last_Line + 2; i++)
{
LineNumberTextBox.Text += i + 1 + "\n";
}
}
private void Form1_Load(object sender, EventArgs e)
{
LineNumberTextBox.Font = richTextBox1.Font;
richTextBox1.Select();
AddLineNumbers();
}
private void richTextBox1_SelectionChanged(object sender, EventArgs e)
{
Point pt = richTextBox1.GetPositionFromCharIndex(richTextBox1.SelectionStart);
if (pt.X == 1)
{
AddLineNumbers();
}
}
private void richTextBox1_VScroll(object sender, EventArgs e)
{
LineNumberTextBox.Text = "";
AddLineNumbers();
LineNumberTextBox.Invalidate();
}
private void richTextBox1_TextChanged(object sender, EventArgs e)
{
if (richTextBox1.Text == "")
{
AddLineNumbers();
}
}
private void richTextBox1_FontChanged(object sender, EventArgs e)
{
LineNumberTextBox.Font = richTextBox1.Font;
richTextBox1.Select();
AddLineNumbers();
}
private void LineNumberTextBox_MouseDown(object sender, MouseEventArgs e)
{
richTextBox1.Select();
LineNumberTextBox.DeselectAll();
}
private void Form1_Resize(object sender, EventArgs e)
{
AddLineNumbers();
}
WORKS 100%!!! But you need to add richTextBox2 for line numbers, if you want change it to other
form like listbox, anyway it served me well.
private void richTextBox1_keyDown(object sender, KeyEventArgs e)
{
for (int i = 0; i <= richTextBox1.Lines.Count(); i++)
{
if (!(e.KeyCode == Keys.Back))
{
if (!richTextBox2.Text.Contains(i.ToString()))
{
richTextBox2.Text += i.ToString() + "\n";
}
}
else
{
richTextBox2.Clear();
}
}
}
