Resize rectangle with form Size in real time?

Here is the following rectangle below:
When I resize the form, I need this rectangle to match the size of the form.
When changing the width of the rectangle, do not interfere with its visibility within the form.
I'm using the following:
Note:
I did the rectangle manually, but if you have rectangle ready, better yet!
public Form1()
{
InitializeComponent();
this.Paint += Form1_Paint;
this.rectangles = new Dictionary<string, Rectangle>();
this.sizeScreen = this.Size;
this.sizeRectangles = new Size(8, 8);
this.brush = new SolidBrush(Color.Red);
FillLeft();
FillRight();
FillUp();
FillDown();
}
private Size sizeScreen;
private Size sizeRectangles;
private SolidBrush brush;
private Dictionary<string, Rectangle> rectangles;
private void FillLeft()
{
Rectangle rectangle = new Rectangle()
{
Height = this.sizeScreen.Height,
Width = this.sizeRectangles.Width,
X = 0,
Y = this.sizeRectangles.Height
};
this.rectangles.Add("left", rectangle);
}
private void FillRight()
{
Rectangle rectangle = new Rectangle()
{
Height = this.sizeScreen.Height,
Width = this.sizeRectangles.Width,
X = this.sizeScreen.Width - (this.sizeRectangles.Width * 5),
Y = this.sizeRectangles.Height
};
this.rectangles.Add("right", rectangle);
}
private void FillUp()
{
Rectangle rectangle = new Rectangle()
{
Height = this.sizeRectangles.Height,
Width = this.sizeScreen.Width,
X = 0,
Y = this.sizeRectangles.Height
};
this.rectangles.Add("up", rectangle);
}
private void FillDown()
{
Rectangle rectangle = new Rectangle()
{
Height = this.sizeRectangles.Height,
Width = this.sizeScreen.Width,
X = 0,
Y = this.sizeScreen.Height - (this.sizeRectangles.Height * 11)
};
this.rectangles.Add("down", rectangle);
}
private void Form1_Paint(object sender, PaintEventArgs e)
{
for (int i = 0; i < this.rectangles.Count; i++)
{
e.Graphics.FillRectangles(this.brush, this.rectangles.Values.ToArray());
}
}
I want to set the rectangle on the form when it is resized
This is the way I'm creating the rectangle, but it does not stay right on the screen, to resize it I do not know

I think this would simplify what you are trying to do:
const int PenWidth = 10;
private void Form1_Paint(object sender, PaintEventArgs e)
{
Rectangle r = this.ClientRectangle;
Pen pen = new Pen(Color.Red, PenWidth);
e.Graphics.DrawRectangle(pen, r);
}
You could even add a margin:
const int PenWidth = 10;
const int PenMargin = 10;
private void Form1_Paint(object sender, PaintEventArgs e)
{
Rectangle r = this.ClientRectangle;
r.Inflate(-PenMargin, -PenMargin);
Pen pen = new Pen(Color.Red, PenWidth);
e.Graphics.DrawRectangle(pen, r);
}
To prevent traces (suggested by Wyck):
private void Form1_Resize(object sender, EventArgs e)
{
Invalidate();
}

Handle the Resize event and call Invalidate in the handler. Create a Pen of the desired color and width and set its Alignment to Inset. Handle the Paint event and in the handler call DrawRectangle passing in the ClientRectangle of the form.
Here is an example.
const float borderWidth = 8.0f;
Pen borderPen = new Pen(Color.Red, borderWidth) { Alignment = System.Drawing.Drawing2D.PenAlignment.Inset };
public Form2()
{
InitializeComponent();
this.Paint += Form2_Paint;
this.Resize += Form2_Resize;
}
private void Form2_Resize(object sender, EventArgs e)
{
Invalidate();
}
private void Form2_Paint(object sender, PaintEventArgs e)
{
e.Graphics.DrawRectangle(borderPen, this.ClientRectangle);
}

Apply the following fixes to the code:
Set ResizeRedraw property of the form to true. It sets the underlying style for the form so by each resize it sends the paint message and you don't need to handle Resize event.
Use DrawRectangle and draw using wide pen. So you don't need to fill multiple rectangles.
Set the PenAlignment to Inset. So you don't need to calculate the location of rectangle.
Do dispose the pen when you don't need it.
Example
public Form1()
{
InitializeComponent();
ResizeRedraw = true;
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
using (var pen = new Pen(Color.Red, PenWidth))
{
pen.Alignment = System.Drawing.Drawing2D.PenAlignment.Inset;
e.Graphics.DrawRectangle(pen, ClientRectangle);
}
}

i have used this on my current project. when ever you resize the form, it will automatically resize all the object inside your form
i have class named clsResize and i call this on the form load.
1st you have to initialize the class inside the form then create 2 new method.
see example below
public partial class frmNewForm : Form
{
clsResize _form_resize;
public string selectedProd;
public frmNewForm()
{
InitializeComponent();
_form_resize = new clsResize(this);
this.Load += _Load;
this.Resize += _Resize;
}
private void _Load(object sender, EventArgs e)
{
_form_resize._get_initial_size();
}
private void _Resize(object sender, EventArgs e)
{
_form_resize._resize();
}
}
and here is the class that i used.
public class clsResize
{
List<System.Drawing.Rectangle> _arr_control_storage = new List<System.Drawing.Rectangle>();
private bool showRowHeader = false;
public clsResize(Form _form_)
{
form = _form_; //the calling form
_formSize = _form_.ClientSize; //Save initial form size
_fontsize = _form_.Font.Size; //Font size
}
private float _fontsize { get; set; }
private System.Drawing.SizeF _formSize {get;set; }
private Form form { get; set; }
public void _get_initial_size() //get initial size//
{
var _controls = _get_all_controls(form);//call the enumerator
foreach (Control control in _controls) //Loop through the controls
{
_arr_control_storage.Add(control.Bounds); //saves control bounds/dimension
//If you have datagridview
if (control.GetType() == typeof(DataGridView))
_dgv_Column_Adjust(((DataGridView)control), showRowHeader);
}
}
public void _resize() //Set the resize
{
double _form_ratio_width = (double)form.ClientSize.Width /(double)_formSize.Width; //ratio could be greater or less than 1
double _form_ratio_height = (double)form.ClientSize.Height / (double)_formSize.Height; // this one too
var _controls = _get_all_controls(form); //reenumerate the control collection
int _pos = -1;//do not change this value unless you know what you are doing
try
{
foreach (Control control in _controls)
{
// do some math calc
_pos += 1;//increment by 1;
System.Drawing.Size _controlSize = new System.Drawing.Size((int)(_arr_control_storage[_pos].Width * _form_ratio_width),
(int)(_arr_control_storage[_pos].Height * _form_ratio_height)); //use for sizing
System.Drawing.Point _controlposition = new System.Drawing.Point((int)
(_arr_control_storage[_pos].X * _form_ratio_width), (int)(_arr_control_storage[_pos].Y * _form_ratio_height));//use for location
//set bounds
control.Bounds = new System.Drawing.Rectangle(_controlposition, _controlSize); //Put together
//Assuming you have a datagridview inside a form()
//if you want to show the row header, replace the false statement of
//showRowHeader on top/public declaration to true;
if (control.GetType() == typeof(DataGridView))
_dgv_Column_Adjust(((DataGridView)control), showRowHeader);
//Font AutoSize
control.Font = new System.Drawing.Font(form.Font.FontFamily,
(float)(((Convert.ToDouble(_fontsize) * _form_ratio_width) / 2) +
((Convert.ToDouble(_fontsize) * _form_ratio_height) / 2)));
}
}
catch(Exception e)
{
MessageBox.Show(e.Message);
return;
}
}
private void _dgv_Column_Adjust(DataGridView dgv, bool _showRowHeader) //if you have Datagridview
//and want to resize the column base on its dimension.
{
int intRowHeader = 0;
const int Hscrollbarwidth = 5;
if (_showRowHeader)
intRowHeader = dgv.RowHeadersWidth;
else
dgv.RowHeadersVisible = false;
for (int i = 0; i < dgv.ColumnCount; i++)
{
if (dgv.Dock == DockStyle.Fill) //in case the datagridview is docked
dgv.Columns[i].Width = ((dgv.Width - intRowHeader) / dgv.ColumnCount);
else
dgv.Columns[i].Width = ((dgv.Width - intRowHeader - Hscrollbarwidth) / dgv.ColumnCount);
}
}
private static IEnumerable<Control> _get_all_controls(Control c)
{
return c.Controls.Cast<Control>().SelectMany(item =>
_get_all_controls(item)).Concat(c.Controls.Cast<Control>()).Where(control =>
control.Name != string.Empty);
}
}

Print the entire area of the control with C#

This is not a duplicat question- the diffenece beetween my question an the others one is my Controler contail a scroller, so they are more informations can't be printed.
I have a C# application that contains a main form name MainForms. This MainForms has a control mainDisplay. I want to print the entire information what we found on the mainDisplay to the printer.
The problem is the information on the the control is too big, and I have to scroll to see all information.
Someone have any function that allow me to print this control MainDisplay with entire information in it?
This the printscreen of the area of my MainDisplay at the right you see the scrollbar:
I use this Function (Source : Printing a control)
private static void PrintControl(Control control)
{
var bitmap = new Bitmap(control.Width, control.Height);
control.DrawToBitmap(bitmap, new Rectangle(0, 0, control.Width, control.Height));
var pd = new PrintDocument();
pd.PrintPage += (s, e) => e.Graphics.DrawImage(bitmap, 100, 100);
pd.Print();
}
But my problem still can't print all the informations contain in my control, it's just print a small erea, still need print more informations which are not printed.

I find the solution. This is the steps i do :
1 - We have a mainForm, and this main form contain a control mainDisplay with a specific dimension and area, let's say this dimensions is smaller and we get scroll.
2- What i do is i make this mainDisplay Empty.
3- i create an other Control myControlToDisplay. I draw and i put all fields i want without scroll, so this one myControlToDisplay will have a big dimension.
4- on the star-up of my application, i tell to the mainDisplay to load myControlToDisplay. This time all the content of myControlToDisplay will be display on mainDisplay with a scroll. Because mainDisplay have a small area.
5- I write this functions :
Bitmap MemoryImage;
PrintDocument printDoc = new PrintDocument();
PrintDialog printDialog = new PrintDialog();
PrintPreviewDialog printDialogPreview = new PrintPreviewDialog();
Control panel = null;
public void Print(Control pnl)
{
DateTime saveNow = DateTime.Now;
string datePatt = #"yyyy-M-d_hh-mm-ss tt";
panel = pnl;
GetPrintArea(pnl);
printDialog.AllowSomePages = true;
printDoc.PrintPage += new PrintPageEventHandler(Print_Details);
printDialog.Document = printDoc;
printDialog.Document.DocumentName = "Document Name";
//printDialog.ShowDialog();
if (printDialog.ShowDialog() == DialogResult.OK)
{
printDoc.Print();
}
}
public void PrintPreview(Control pnl)
{
DateTime saveNow = DateTime.Now;
string datePatt = #"yyyy-M-d_hh-mm-ss tt";
panel = pnl;
GetPrintArea(pnl);
printDoc.PrintPage += new PrintPageEventHandler(Print_Details);
printDialogPreview.Document = printDoc;
printDialogPreview.Document.DocumentName = "Document Name";
//printDialog.ShowDialog();
if (printDialogPreview.ShowDialog() == DialogResult.OK)
{
printDoc.Print();
}
}
private void Print_Details(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
RectangleF marginBounds = e.MarginBounds;
DateTime saveNow = DateTime.Now;
string datePatt = #"M/d/yyyy hh:mm:ss tt";
//String dtString = saveNow.ToString(datePatt);
// create header and footer
string header = "Put all information you need to display on the Header";
string footer = "Print date : " + saveNow.ToString(datePatt);
Font font = new Font("times new roman", 10, System.Drawing.FontStyle.Regular);
Brush brush = new SolidBrush(Color.Black);
// measure them
SizeF headerSize = e.Graphics.MeasureString(header, font);
SizeF footerSize = e.Graphics.MeasureString(footer, font);
// draw header
RectangleF headerBounds = new RectangleF(marginBounds.Left-80, marginBounds.Top-80, marginBounds.Width, headerSize.Height);
e.Graphics.DrawString(header, font, brush, headerBounds);
// draw footer
RectangleF footerBounds = new RectangleF(marginBounds.Left-80, marginBounds.Bottom - footerSize.Height+80, marginBounds.Width, footerSize.Height);
e.Graphics.DrawString(footer, font, brush, footerBounds);
// dispose objects
font.Dispose();
brush.Dispose();
}
public void GetPrintArea(Control pnl)
{
MemoryImage = new Bitmap(pnl.Width, pnl.Height);
Rectangle rect = new Rectangle(0, 0, pnl.Width, pnl.Height);
pnl.DrawToBitmap(MemoryImage, new Rectangle(0, 0, pnl.Width, pnl.Height));
}
protected override void OnPaint(PaintEventArgs e)
{
if (MemoryImage != null)
{
e.Graphics.DrawImage(MemoryImage, 0, 0);
base.OnPaint(e);
}
}
void PrintDoc_PrintPage(object sender, PrintPageEventArgs e)
{
Rectangle pageArea = e.PageBounds;
Rectangle m = e.MarginBounds;
if ((double)MemoryImage.Width / (double)MemoryImage.Height > (double)m.Width / (double)m.Height) // image is wider
{
m.Height = (int)((double)MemoryImage.Height / (double)MemoryImage.Width * (double)m.Width);
}
else
{
m.Width = (int)((double)MemoryImage.Width / (double)MemoryImage.Height * (double)m.Height);
}
e.Graphics.DrawImage(MemoryImage, m);
}
6 -And finally we suppose that we have two buttons, one to Print and the other one to print preview.
You just have to call this function :
private void PrintButton_Click(object sender, EventArgs e)
{
try
{
Print(mainDisplay.getCurentPanel());
}
catch (Exception exp)
{
MessageBox.Show("Error: \n" + exp.Message);
}
}
private void PrintPreviewButton_Click(object sender, EventArgs e)
{
try
{
PrintPreview(mainDisplay.getCurentPanel());
}
catch (Exception exp)
{
MessageBox.Show("Error: \n" + exp.Message);
}
}
Hope it will help someone :)
good luck

C# Save modified image in panel

I am attempting to save an image as modified by graphics tools such as pens and shapes that can be drawn onto the image. I have done this using a panel with background image and trying to set up a bit map that will save changes within this panel:
private void saveToolStripButton_Click(object sender, EventArgs e)
{
//sets panel1 contents as bit map to be saved at set locations
int width = panel1.Size.Width;
int height = panel1.Size.Height;
using (Bitmap bmp = new Bitmap(width, height))
{
panel1.DrawToBitmap(bmp, new Rectangle(0, 0, width, height));
bmp.Save(#"C:\Users\Me\Pics\testBitmap.jpeg", ImageFormat.Jpeg);
}
MessageBox.Show("Your image has been saved");
}
Once the save button is clicked, the image saves ok but the changes made with the graphics tools do not show up. Can anyone suggest a solution?
Here is some code regarding the graphics tool i've set up for use within the panel:
{
InitializeComponent();
//Create graphics object in panel1
g = panel1.CreateGraphics();
}
private void btnExit2_Click(object sender, EventArgs e)
{
this.Close();
}
Graphics g;
//set a drawing boolean
bool draw = false;
private void panel1_MouseDown(object sender, MouseEventArgs e)
{
draw = true;
if (drawSq)
{
SolidBrush brush = new SolidBrush(Color.FromArgb(128, 255, 0, 0));
if (toolStripTextBox1.Text != "")
{
g.FillRectangle(brush, e.X, e.Y, Convert.ToInt32(toolStripTextBox1.Text), Convert.ToInt32(toolStripTextBox1.Text));
}
else if (toolStripTextBox1.Text == "")
{
MessageBox.Show("Please enter a shape size");
}
draw = false;
drawSq = false;
}
}
and more:
private void panel1_MouseUp(object sender, MouseEventArgs e)
{
draw = false;
mouseX = null;
mouseY = null;
}
//null values allow freehand style drawing
int? mouseX = null;
int? mouseY = null;
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
//creates a pen tool and sets properties by mouse location
if (draw)
{
Pen pen = new Pen(btnColor.ForeColor, float.Parse(txtBox1.Text));
g.DrawLine(pen, new Point(mouseX ?? e.X, mouseY ?? e.Y), new Point(e.X, e.Y));
mouseX = e.X;
mouseY = e.Y;
}
}

Let's try to fix this.
Start by creating your image first:
Bitmap bmp;
protected override void OnLoad(EventArgs e) {
base.OnLoad(e);
bmp = new Bitmap(panel1.ClientSize.Width, panel1.ClientSize.Height);
}
Now when you want to draw on it:
void panel1_MouseMove(object sender, MouseEventArgs e) {
if (e.Button == MouseButtons.Left) {
using (Graphics g = Graphics.FromImage(bmp)) {
g.FillEllipse(Brushes.Red, new Rectangle(e.X - 4, e.Y - 4, 8, 8));
}
panel1.Invalidate();
}
}
And display the results:
void panel1_Paint(object sender, PaintEventArgs e) {
e.Graphics.DrawImage(bmp, Point.Empty);
}
To save, just use your bitmap:
bmp.Save(#"c:\filename.png", ImageFormat.Png);
Use Double buffering with Panel to avoid the flickering.

This will works fine. I tested it and worked well........

Windows Form TextBox to show images

I currently have a Windows Form project where I have created a simple chat application. Currently the chat is output to a multi line text box, however I want to now enhance it a little and add some styling. In time I wish to have some image, format it nicely and perhaps some HTML (although this isnt vital) in the future. I am just wondering what I should use to achieve this. I did think of updating a HTML page and then reload it with each new message, but this wouldn't give a very good user experience. I have also looked at the richtextbox class but this seems to be a little limited for what I am after. I am hoping some one can point me in the right direction as to what to use.
I am trying to achieve something similar as what I have highlighted in red:

While some of the other comments indicate that WPF is well suited to this, in the real world, it is not always possible or desirable to switch.
A regular owner-drawn list box is well suited to this purpose.
To create one, simply set the DrawMode on the list box to OwnerDrawVariable, e.g.
list.DrawMode = System.Windows.Forms.DrawMode.OwnerDrawVariable;
Then you just need to provide two event handlers, the first to measure the item (tell the list box how tall the item will be), and another to actually render it. e.g.
this.list.DrawItem += new System.Windows.Forms.DrawItemEventHandler(this.list_DrawItem);
this.list.MeasureItem += new System.Windows.Forms.MeasureItemEventHandler(this.list_MeasureItem);
Rendering an image into the list is fairly simple with GDI+ DrawImage (where g is your graphics context_:
Bitmap bmp = Bitmap.FromFile("test.jpg");
Rectangle source = new Rectangle(0, 0, bmp.Width, bmp.Height);
Rectangle dest = source;
g.DrawImage(bmp, dest, source, GraphicsUnit.Pixel);
This is a sample Windows Form which has an owner-drawn list box of all fonts on the system, producing variable-height owner-drawn list items:

How to print a full size image in c#

I am trying to print an image in C#. It is a full 8.5x11 size tiff created by Adobe Acrobat from a PDF. When I print it with C# using the code below, it prints correct vertically, but not horizontally, where it is pushed over about a half inch. I set the origin of the image to 0,0. Am I missing something?
private FileInfo _sourceFile;
public void Print(FileInfo doc, string printer, int tray)
{
_sourceFile = doc;
PrintDocument pd = new PrintDocument();
pd.PrinterSettings.PrinterName = printer;
pd.DocumentName = _sourceFile.FullName;
using (Image img = Image.FromFile(_sourceFile.FullName)) {
if (img.Width > img.Height) {
pd.DefaultPageSettings.Landscape = true;
}
}
pd.PrintPage += PrintPage;
foreach (PaperSource ps in pd.PrinterSettings.PaperSources) {
if (ps.RawKind == tray) {
pd.DefaultPageSettings.PaperSource = ps;
}
}
pd.Print();
}
private void PrintPage(object o, PrintPageEventArgs e)
{
using (System.Drawing.Image img = System.Drawing.Image.FromFile(_sourceFile.FullName)) {
Point loc = new Point(0, 0);
e.Graphics.DrawImage(img, loc);
}
}

look at the code from this below for a good example this code is from this link below
Print Image in C#
private void PrintImage()
{
PrintDocument pd = new PrintDocument();
pd.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
pd.OriginAtMargins = false;
pd.DefaultPageSettings.Landscape = true;
pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
printPreviewDialog1.Document = pd;
printPreviewDialog1.ShowDialog();
//pd.Print();
}
void pd_PrintPage(object sender, PrintPageEventArgs e)
{
double cmToUnits = 100 / 2.54;
e.Graphics.DrawImage(bmIm, 100, 1000, (float)(15 * cmToUnits), (float)(10 * cmToUnits));
}
private void button5_Click(object sender, EventArgs e)
{
PrintImage();
}
