The string formats just fine in command line but in gui with a label it is all off. I think my formatting is correct
Example:
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace DisplayMultiplicationTableGUI
{
public partial class Form1 : Form
{
int i, j;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
label1.Text = String.Format("{0,3}", " ");
for (i = 1; i <= 10; i++)
label1.Text += String.Format(" {0,3}", (i).ToString());
for (i = 1; i <= 10; i++)
label2.Text += String.Format("\n{0,3} ", (i).ToString());
for (i = 1; i <= 10; i++)
{
for (j = 1; j <= 10; j++)
label3.Text += String.Format("{0,3} ", (i*j).ToString());
label3.Text += String.Format("\n");
}
}
}
}
}
The easiest way to solve this is to use a fixed-width font. You're never going to get this to line up correctly with a proportional font, unless you put each number in its own label or text box, or use a DataGridView.

I have a customTextBox1 on a Form.
customTextbox1 multiline is false and TextAlign is set to center.MaxLength is 23. And the customTextBox1 width is 92.customTextBox1 Font is set to "ＭＳ ゴシック", 12F.
When I type "12345678901234567890123" in the TextBox, the text is scrolling to the last character.Also,when I click on the text , the text is highlighted blue and I can drag to the left and right of the text.
.NetFramework 3.5
What I want is 2 things:
1)when the text is longer than TextBox width, I don't want to scroll to the last character.I want to stop scrolling at the right margin of the TextBox.
for example,
when I type "1234567890123456", I want to show "12345678901"and the rest of the overflow text should not be shown.
2)when I Click and Drag the text, I want to show "12345678901" only
And want to get rid of the blue highlighted selection too.
1)overflow text is showing
2)i can click and drag to the end of the text and beginning of the text
here is my code
CustomTextBox
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace DisabledTextSelectForm
{
public partial class CustomTextBox : TextBox
{
public override bool AutoSize
{
get { return base.AutoSize; }
set { base.AutoSize = value; }
}
public CustomTextBox()
{
InitializeComponent();
}
}
}
Form1
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace DisabledTextSelectForm
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
customTextBox1.AutoSize = true;
customTextBox1.Size = new Size(92,21);
customTextBox1.Multiline = false;
customTextBox1.TextAlign = HorizontalAlignment.Center;
customTextBox1.MaxLength = 23;
customTextBox1.Font = new Font("ＭＳ ゴシック", 12F);
}
}
}
Update1 :
I want to do this strange behavior of textBox because I am making a exact replica of an application written in other language which is not supported anymore. So we have to write it in C#. Both application will run on windows.
In the old application, there is a textBox in which user can type in ID numbers.
1)That textBox does not show overflow text.
If I type ("12345678901234567890123") ,it only show "12345678901" but if I click backspace [13]times, the text begins "1234567890". so I know the overflow text are there just not showing.
2)I can't click and drag the text right and left as in C# textBox.
I have manage to replicate No.1 behavior though.
Here is my code
CustomTextBox

using System.Collections.Generic;
using System.ComponentModel;

public partial class CustomTextBox : TextBox
{
public override bool AutoSize
{
get { return base.AutoSize; }
set { base.AutoSize = value; }
}
public bool DisabledScrolling { get; set; }
int caretPos = 0;
public CustomTextBox()
{
InitializeComponent();
}
protected override void OnKeyPress(KeyPressEventArgs e)
{
var isDigit = char.IsDigit(e.KeyChar);
var isBackSpace = e.KeyChar == (char)Keys.Back;
var diffWidth = 0;
if (Text.Length >= 2)
{
var firstChar = TextRenderer.MeasureText(Text[0].ToString(), Font);
var secondChar = TextRenderer.MeasureText(Text.Substring(0, 2).ToString(), Font);
diffWidth = secondChar.Width - firstChar.Width;
caretPos = Width / diffWidth;
}
if (caretPos != 0 && Text.Length >= caretPos && DisabledScrolling)
{
if (isDigit)
{
Text = Text.Length < MaxLength ? Text + e.KeyChar.ToString() : Text;
}
else if (isBackSpace)
{
Text = Text.Substring(0,Text.Length - 1);
}
ScrollTo(caretPos - 1);
e.Handled = true;
}
base.OnKeyPress(e);
}
private void ScrollTo(int scrollPosition)
{
if (Text.Length >= scrollPosition)
{
Select(scrollPosition, 0);
ScrollToCaret();
}
}
}
}

I know how to disable clicking and draging of Text in TextBox.
Add a Timer then set it Enable with 10 ms interval and in Tick event of your Timer put this code:
private void timer1_Tick(object sender, EventArgs e)
{
textBox1.SelectionLength = 0;
textBox1.SelectionStart = 0;
textBox1.ScrollToCaret();
}
In MouseMove event of your TextBox put this code:
private void textBox1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
textBox1.SelectionLength = 0;
textBox1.SelectionStart = 0;
textBox1.ScrollToCaret();
}
In KeyDown event of your TextBox put this code:
private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
textBox1.SelectionStart = textBox1.Text.Length;
}
Add this code in initialize block
public Form1()
{
InitializeComponent();
textBox1.HideSelection = true;
}
I've been following the instructions for an assignment and I can't see any issues with the code (no error messages and the program runs without crashing), but the program does not draw the graphics. It's supposed to random out 200 random numbers between 1-100, and then sort them into a graph with a bubble sort
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApp6
{
public partial class Form1 : Form
{
int[] number = new int[200];
Random generator = new Random();
public Form1()
{
InitializeComponent();
}
private void btnGenerate_Click(object sender, EventArgs e)
{
for (int i = 0; i < number.Length; i++)
{
number[i] = generator.Next(1, 101);
}
Invalidate();
}
private void btnSort_Click(object sender, EventArgs e)
{
BubbleSort(number);
Invalidate();
}
private void Form1_Paint(object sender, PaintEventArgs e)
{
//Assigns origo
Point origo = new Point(40,150);
//Draw x and y axes
e.Graphics.DrawLine(Pens.Black, origo.X, origo.Y, origo.X, origo.Y - 100);
e.Graphics.DrawLine(Pens.Black, origo.X, origo.Y, origo.X + 200, origo.Y);
//Draw all points
for(int i = 0; i < number.Length; i++)
{
e.Graphics.FillEllipse(Brushes.Red, origo.X + i, origo.Y - number[i], 2, 2);
}
}
public void BubbleSort(int[] list)
{
for (int m = list.Length - 1; m > 0; m--)
{
for (int n = 0; n < m; n++)
{
if (list[n] > list[n + 1])
{
int temp = list[n];
list[n] = list[n + 1];
list[n + 1] = temp;
}
}
}
}
}
}
The program should draw 200 points when you press the button "Generate" and then sort them into a line/graph when you press "Sort", but the program isn't drawing anything when I press the buttons.
This is in WinForms. and i am using microsoft.vsualbasic.powerpacks
how can i concatenate Rectangle control name in c# this is what i have so far
string n = "1";
Rectangle match = this.Controls.Find("rectangleShape" + n,true)[0] as Rectangle;
match.BackColor = Color.Red;
Try some of the solutions
here... – Idle_Mind
okay will do try – droid fiji
it didnt really help :( – droid fiji
Here's a working example based on the solution I linked to in the comments. Note that the BackStyle property of your RectangleShape needs to be Opaque for you to see the color you set!
This code will set the BackColor of rectangeShape1 thru rectangeShape3 to Red:
using Microsoft.VisualBasic.PowerPacks;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApp1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string rectName;
string rectBaseName = "rectangleShape";
var shapeContainer = this.Controls.OfType<ShapeContainer>().FirstOrDefault();
if (shapeContainer != null)
{
for (int i = 1; i <= 3; i++)
{
rectName = rectBaseName + i.ToString();
RectangleShape match = shapeContainer.Shapes.OfType<RectangleShape>().FirstOrDefault(o => o.Name == rectName);
if (match != null)
{
match.BackColor = Color.Red;
match.BackStyle = BackStyle.Opaque;
}
}
}
}
}
}
I am creating a number of comboBoxes based on user input. I create the boxes just fine, but when it comes to wanting to check the text within them I am struggling.
I thought of maybe storing them in a IList but that hasn't seemed to work so far. The goal is to change the text of all of them on a button click, but after several attempts I am becoming frustrated.
IList<ComboBox> comboBoxes = new List<ComboBox>();
private void AddComboBox(int i)
{
var comboBoxStudentAttendance = new ComboBox();
comboBoxStudentAttendance.Top = TopMarginDistance(i);
comboBoxStudentAttendance.Items.Add("");
comboBoxStudentAttendance.Items.Add("Present");
comboBoxStudentAttendance.Items.Add("Absent");
comboBoxStudentAttendance.Items.Add("Late");
comboBoxStudentAttendance.Items.Add("Sick");
comboBoxStudentAttendance.Items.Add("Excused");
comboBoxes.Add(comboBoxStudentAttendance);
this.Controls.Add(comboBoxStudentAttendance);
}
I tried the following but with no success.
private void DistributeAttendanceButton_Click(object sender, EventArgs e)
{
for (int i = 0; i < sampleNum; i++)
{
switch (MasterComboBox.Text)
{
case "Present":
comboBoxes.ElementAt(i).Text = "Present";
break;
}
}
}
Try this
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1

const int TOP_MARGIN = 10;
const int LEFT_MARGIN = 10;
const int WIDTH = 200;
const int HEIGHT = 10;
const int SPACE = 15;
const int NUMBER_OF_BOXES = 10;
public Form1()
{
InitializeComponent();
MasterComboBox.Text = "Present";
for (int i = 0; i < NUMBER_OF_BOXES; i++)
{
AddComboBox(i);
}
}
List<ComboBox> comboBoxes = new List<ComboBox>();
private void AddComboBox(int i)
{
var comboBoxStudentAttendance = new ComboBox();
comboBoxStudentAttendance.Top = TOP_MARGIN + i * (SPACE + HEIGHT);
comboBoxStudentAttendance.Left = LEFT_MARGIN;
comboBoxStudentAttendance.Width = WIDTH;
comboBoxStudentAttendance.Height = HEIGHT;
comboBoxStudentAttendance.Items.Add("");
comboBoxStudentAttendance.Items.Add("Present");
comboBoxStudentAttendance.Items.Add("Absent");
comboBoxStudentAttendance.Items.Add("Late");
comboBoxStudentAttendance.Items.Add("Sick");
comboBoxStudentAttendance.Items.Add("Excused");
comboBoxes.Add(comboBoxStudentAttendance);
this.Controls.Add(comboBoxStudentAttendance);
}
private void DistributeAttendanceButton_Click(object sender, EventArgs e)
{
for (int i = 0; i < comboBoxes.Count; i++)
{
switch (MasterComboBox.Text)
{
case "Present":
comboBoxes[i].Text = "Present";
break;

}
private void richTextBox1_MouseEnter(object sender, EventArgs e)
{
HighlightPhrase(richTextBox1, "http", Color.Green);
}
}
}
When im running the program its painting all the http words in the richTextBox1 in Red.
When i enter with the mouse over the richTextBox1 area it will paint all the http words in Green.
But each time im entering the richTextBox1 area its loading like loading over again the text into the richTextBox and then change the colors.
I guess but not sure its the FOR loop in the HighlightPhrase method.
Is there anyway to make it to change the colors without like loading all the text over again ?
It was not loading richtextbox again and again on mouse enter. It just scroll on the start position when you enter mouse in it. I have checked this by removing position lines. Try as given below.
static void HighlightPhrase(RichTextBox box, string phrase, Color color)
{
string s = box.Text;
for (int ix = 0; ; )
{
int jx = s.IndexOf(phrase, ix, StringComparison.CurrentCultureIgnoreCase);
if (jx < 0) break;
box.SelectionStart = jx;
box.SelectionLength = phrase.Length;
box.SelectionColor = color;
ix = jx + 1;
}
}
