I am developing a windows form application. Creating a UI for some service. What is happening is when I created the application there are various buttons on which a single click should work to get and set the value but after the completion of code all those buttons are reacting on double click.
when we apply some break point and test, values get and set in single click only but during run-time it need double click. Can anybody help?
I got the solution by writing a piece of code.
Just activated the button on first click.
bool firstClick = true;
{if(firstClick) { button.select(); //Activating the button } }
Thanks all for your responses.
Here is a full Article from MSDN on how to use single-click only vs double-click only. Also, it states how you can handle events and differentiate between a single click and a double click.
The article uses boolean and timers to do that. You might need to use a Dictionary<Button, boolean> if you have multiple buttons. Hope it helps.
Here is the example if the link got down or removed for some reaosn:
Handle the MouseDown event and determine the location and time span
between clicks using the appropriate SystemInformation properties and
a Timer component. Perform the appropriate action depending on whether
a click or double-click takes place. The following code example
demonstrates how this can be done.
class Form1 : Form
{
private Rectangle hitTestRectangle = new Rectangle();
private Rectangle doubleClickRectangle = new Rectangle();
private TextBox textBox1 = new TextBox();
private Timer doubleClickTimer = new Timer();
private ProgressBar doubleClickBar = new ProgressBar();
private Label label1 = new Label();
private Label label2 = new Label();
private bool isFirstClick = true;
private bool isDoubleClick = false;
private int milliseconds = 0;
[STAThread]
public static void Main()
{
Application.EnableVisualStyles();
Application.Run(new Form1());
}
public Form1()
{
label1.Location = new Point(30, 5);
label1.Size = new Size(100, 15);
label1.Text = "Hit test rectangle:";
label2.Location = new Point(30, 70);
label2.Size = new Size(100, 15);
label2.Text = "Double click timer:";
hitTestRectangle.Location = new Point(30, 20);
hitTestRectangle.Size = new Size(100, 40);
doubleClickTimer.Interval = 100;
doubleClickTimer.Tick +=
new EventHandler(doubleClickTimer_Tick);
doubleClickBar.Location = new Point(30, 85);
doubleClickBar.Minimum = 0;
doubleClickBar.Maximum = SystemInformation.DoubleClickTime;
textBox1.Location = new Point(30, 120);
textBox1.Size = new Size(200, 100);
textBox1.AutoSize = false;
textBox1.Multiline = true;
this.Paint += new PaintEventHandler(Form1_Paint);
this.MouseDown += new MouseEventHandler(Form1_MouseDown);
this.Controls.AddRange(new Control[] { doubleClickBar, textBox1,
label1, label2 });
}
// Detect a valid single click or double click.
void Form1_MouseDown(object sender, MouseEventArgs e)
{
// Verify that the mouse click is in the main hit
// test rectangle.
if (!hitTestRectangle.Contains(e.Location))
{
return;
}
// This is the first mouse click.
if (isFirstClick)
{
isFirstClick = false;
// Determine the location and size of the double click
// rectangle area to draw around the cursor point.
doubleClickRectangle = new Rectangle(
e.X - (SystemInformation.DoubleClickSize.Width / 2),
e.Y - (SystemInformation.DoubleClickSize.Height / 2),
SystemInformation.DoubleClickSize.Width,
SystemInformation.DoubleClickSize.Height);
Invalidate();
// Start the double click timer.
doubleClickTimer.Start();
}
// This is the second mouse click.
else
{
// Verify that the mouse click is within the double click
// rectangle and is within the system-defined double
// click period.
if (doubleClickRectangle.Contains(e.Location) &&
milliseconds < SystemInformation.DoubleClickTime)
{
isDoubleClick = true;
}
}
}
void doubleClickTimer_Tick(object sender, EventArgs e)
{
milliseconds += 100;
doubleClickBar.Increment(100);
// The timer has reached the double click time limit.
if (milliseconds >= SystemInformation.DoubleClickTime)
{
doubleClickTimer.Stop();
if (isDoubleClick)
{
textBox1.AppendText("Perform double click action");
textBox1.AppendText(Environment.NewLine);
}
else
{
textBox1.AppendText("Perform single click action");
textBox1.AppendText(Environment.NewLine);
}
// Allow the MouseDown event handler to process clicks again.
isFirstClick = true;
isDoubleClick = false;
milliseconds = 0;
doubleClickBar.Value = 0;
}
}
// Paint the hit test and double click rectangles.
void Form1_Paint(object sender, PaintEventArgs e)
{
// Draw the border of the main hit test rectangle.
e.Graphics.DrawRectangle(Pens.Black, hitTestRectangle);
// Fill in the double click rectangle.
e.Graphics.FillRectangle(Brushes.Blue, doubleClickRectangle);
}
}
You can simply identify single click and double using a timer. Here is the example
class Form1 : Form
{
Timer timer;
public Form1()
{
InitializeComponent();
timer = new Timer();
timer.Interval = 500;
timer.Tick += new EventHandler(Timer_Tick);
}
private void App_MouseDown(object sender, MouseEventArgs e)
{
if (e.Clicks == 1)
{
timer.Start();
}
else
{
timer.Stop();
doubleClick();
}
}
private void Timer_Tick(object sender, EventArgs e)
{
timer.Stop();
singleClick();
}
//Single click
public void singleClick()
{
MessageBox.Show("Single Click.");
}
//Double click
public void doubleClick()
{
MessageBox.Show("Double Click.");
}
}

I am using Windows Forms (.NET Framework) and am trying to make a picture box move a cross a screen.
I have tried using timers and this while loop but the image (it's supposed to be a plane) does not appear in the case of the while loop and the use of timers makes it difficult to remove past picture Boxes so they appear to generate a sequence of planes. How can I accomplish this?Does it have something to do with Sleep()?
private void Button1_Click(object sender, EventArgs e)
{
//airplane land
//drawPlane(ref locx, ref locy);
//timer1.Enabled = true;
while (locx > 300)
{
var picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(30, 30),
Location = new System.Drawing.Point(locx, locy),
Image = Properties.Resources.plane2, //does not appear for some reason
};
this.Controls.Add(picture);
Thread.Sleep(500);
this.Controls.Remove(picture);
picture.Dispose();
locx = locx - 50;
}
You can use a "Timer" to change the position of the PictureBox regularly.
Here is a simple demo that using Timer Class you can refer to.
public partial class Form1 : Form
{
private System.Timers.Timer myTimer;
public Form1()
{
InitializeComponent();
myTimer = new System.Timers.Timer(100);
myTimer.Elapsed += new System.Timers.ElapsedEventHandler(myTimer_Elapsed);
myTimer.AutoReset = true;
myTimer.SynchronizingObject = this;
}
private void myTimer_Elapsed(object sender, ElapsedEventArgs e)
{
pictureBox1.Location = new Point(pictureBox1.Location.X + 1, pictureBox1.Location.Y);
}
private void btStart_Click(object sender, EventArgs e)
{
myTimer.Enabled = true;
}
}
The result,
In my code, every time button1 is pressed an instance of a picturebox called NOT is spawned in a panel. When the image is clicked and held on it can be dragged around. My question is every time button1 is pressed I want another pictureBox of the same properties to be created so that theoretically I could press button1 all day and drag around as many NOT picturebox objects around as I want. So far once the button is pressed only one instance of NOT is created and another cannot be spawned. So essentially how do make new unique instances of NOT every time button1 is pressed.
public Form1()
{
InitializeComponent();
Drag();
}
private void button1_Click(object sender, EventArgs e)
{
spawnGate("not");
}
PictureBox NOT = new PictureBox();
private Point startPoint = new Point();
public void Drag()
{
NOT.MouseDown += (ss, ee) =>
{
if (ee.Button == System.Windows.Forms.MouseButtons.Left)
{
startPoint = Control.MousePosition;
}
};
NOT.MouseMove += (ss, ee) =>
{
if (ee.Button == System.Windows.Forms.MouseButtons.Left)
{
Point temp = Control.MousePosition;
Point res = new Point(startPoint.X - temp.X, startPoint.Y - temp.Y);
NOT.Location = new Point(NOT.Location.X - res.X, NOT.Location.Y - res.Y);
startPoint = temp;
}
};
}
public void spawnGate(string type)
{
switch (type)
{
case "not":
NOT.Width = 100;
NOT.Height = 50;
NOT.Image = Properties.Resources.Not_gate;
NOT.SizeMode = PictureBoxSizeMode.Zoom;
workspace.Controls.Add(NOT);
break;
}
}
}
Change NOT to a List<PictureBox>.
Then, add a new PictureBox instance to NOT in the spawnGate() method. Note that Drag() will need to be changed to take a PictureBox argument.
Edit: As requested in the comments, for the benefit of others visiting this question, here is exactly how the code would need to be changed to get the behavior requested by OP. Note that this design could and should be refactored in a few areas.
List<PictureBox> NOT = new List<PictureBox>();
Point startPoint = new Point();
public Form1()
{
InitializeComponent();
Drag();
}
private void button1_Click(object sender, EventArgs e)
{
spawnGate();
}
public void spawnGate()
{
var pictureBox = new PictureBox()
{
Width = 100,
Height = 50,
Image = Properties.Resources.Not_gate,
SizeMode = PictureBoxSizeMode.Zoom
}
Drag(pictureBox);
NOT.Add(pictureBox);
workspace.Controls.Add(pictureBox);
}
public void Drag(PictureBox pictureBox)
{
pictureBox.MouseDown += (ss, ee) =>
{
if (ee.Button == System.Windows.Forms.MouseButtons.Left)
startPoint = Control.MousePosition;
};
pictureBox.MouseMove += (ss, ee) =>
{
if (ee.Button == System.Windows.Forms.MouseButtons.Left)
{
Point temp = Control.MousePosition;
Point res = new Point(startPoint.X - temp.X, startPoint.Y - temp.Y);
pictureBox.Location = new Point(pictureBox.Location.X - pictureBox.X, pictureBox.Location.Y - res.Y);
startPoint = temp;
}
};
}
You don't have to save the pointer to NOT on the form directly (or you could save them to a list if you need to call them at a later point).
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
spawnGate("not");
}
// This list is optional, if you easily want to find them later
List<PictureBox> allNOTs = new List<PictureBox>();
public void spawnGate(string type)
{
switch (type)
{
case "not":
PictureBox NOT = new PictureBox();
NOT.Width = 100;
NOT.Height = 50;
NOT.Image = Properties.Resources.Not_gate;
NOT.SizeMode = PictureBoxSizeMode.Zoom;
NOT.MouseDown += (ss, ee) =>
{
// Mouse down event code here
};
NOT.MouseMove += (ss, ee) =>
{
// Mouse move event code here
};
allNOTS.Add(NOT); // Optional if you easily want to find it later
workspace.Controls.Add(NOT);
break;
}
}
}

How to move and resize a form without a border?
(7 answers)
Closed 7 years ago.
I have created a border-less form using c# but could make the custom title bar movable so I search the internet and found this code:
protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
if (m.Msg == WM_NCHITTEST)
m.Result = (IntPtr)(HT_CAPTION);
}
private const int WM_NCHITTEST = 0x84;
private const int HT_CLIENT = 0x1;
private const int HT_CAPTION = 0x2;
After applying this code can click and drag my form in every inch of the form except for the title bar .
This is a good example of the movable title bar.
This is a full example
using System;
using System.Drawing;
using System.Windows.Forms;
namespace Custom_Title_Bar
{
public partial class MainForm : Form
{
private PictureBox title = new PictureBox(); // create a PictureBox
private Label minimise = new Label(); // this doesn't even have to be a label!
private Label maximise = new Label(); // this will simulate our this.maximise box
private Label close = new Label(); // simulates the this.close box
private bool drag = false; // determine if we should be moving the form
private Point startPoint = new Point(0, 0); // also for the moving
public MainForm()
{
this.FormBorderStyle = FormBorderStyle.None;// get rid of the standard title bar
this.title.Location = this.Location; // assign the location to the form location
this.title.Width = this.Width; // make it the same width as the form
this.title.Height = 50; // give it a default height (you may want it taller/shorter)
this.title.BackColor = Color.Black; // give it a default colour (or load an image)
this.Controls.Add(this.title); // add it to the form's controls, so it gets displayed
// if you have an image to display, you can load it, instead of assigning a bg colour
// this.title.Image = new Bitmap(System.Environment.CurrentDirectory + "\\title.jpg");
// if you displayed an image, alter the SizeMode to get it to display as you want it to
// examples:
// this.title.SizeMode = PictureBoxSizeMode.StretchImage;
// this.title.SizeMode = PictureBoxSizeMode.CenterImage;
// this.title.SizeMode = PictureBoxSizeMode.Zoom;
// etc
// you may want to use PictureBoxes and display images
// or use buttons, there are many alternatives. This is a mere example.
this.minimise.Text = "Minimise"; // Doesn't have to be
this.minimise.Location = new Point(this.Location.X + 5, this.Location.Y + 5); // give it a default location
this.minimise.ForeColor = Color.Red; // Give it a colour that will make it stand out
// this is why I didn't use an image, just to keep things simple:
this.minimise.BackColor = Color.Black; // make it the same as the PictureBox
this.Controls.Add(this.minimise); // add it to the form's controls
this.minimise.BringToFront(); // bring it to the front, to display it above the picture box
this.maximise.Text = "Maximise";
// remember to make sure it's far enough away so as not to overlap our minimise option
this.maximise.Location = new Point(this.Location.X + 60, this.Location.Y + 5);
this.maximise.ForeColor = Color.Red;
this.maximise.BackColor = Color.Black; // remember, we want it to match the background
this.maximise.Width = 50;
this.Controls.Add(this.maximise); // add it to the form
this.maximise.BringToFront();

this.close.BackColor = Color.Black;
this.close.Width = 37; // this is just to make it fit nicely
this.Controls.Add(this.close);
this.close.BringToFront();
// now we need to add some functionality. First off, let's give those labels
// MouseHover and MouseLeave events, so they change colour
// Since they're all going to change to the same colour, we can give them the same
// event handler, which saves time of writing out all those extra functions
this.minimise.MouseEnter += new EventHandler(Control_MouseEnter);
this.maximise.MouseEnter += new EventHandler(Control_MouseEnter);
this.close.MouseEnter += new EventHandler(Control_MouseEnter);
// and we need to do the same for MouseLeave events, to change it back
this.minimise.MouseLeave += new EventHandler(Control_MouseLeave);
this.maximise.MouseLeave += new EventHandler(Control_MouseLeave);
this.close.MouseLeave += new EventHandler(Control_MouseLeave);
// and lastly, for these controls, we need to add some functionality
this.minimise.MouseClick += new MouseEventHandler(Control_MouseClick);
this.maximise.MouseClick += new MouseEventHandler(Control_MouseClick);

} // end of the namespace
If you want you can extract just the moving code and integrate it with your code, the movable Title code is just in the following Event Handlers
Title_MouseUp
Title_MouseDown
Title_MouseMove
Here is the original article for this code, you can read it for more explanation about the code

I've got a smaller image in my form. When the user hovers over the image it brings up a larger view of the image (that follows the mouse, but stays a certain distance from the mouse). In order to do this I am generating a Form with no FormBorderStyles when the cursor hovers the image.
The problem I'm running into is that the first form doesn't seem to detect any longer that the mouse is hovering or leaving the PictureBox once the form activates. The Form also doesn't follow the cursor.
Here is the slimmed down version of what I've got:
C#
bool formOpen = false;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
pictureBox1.MouseHover += pictureBox1_MouseHover;
pictureBox1.MouseLeave +=pictureBox1_MouseLeave;
}
void pictureBox1_MouseHover(object sender, EventArgs e)
{
if (formOpen == false)
{
Form form = new Form();
form.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
form.BackColor = Color.Orchid;
//Show the form
form.Show();
form.Name = "imageForm";
this.AddOwnedForm(form);
//Set event handler for when the mouse leaves the image area.
//form.MouseLeave += form_MouseLeave;
//Set the location of the form and size
form.BackColor = Color.Black;
form.Dock = DockStyle.Fill;
form.Size = new Size(30, 30);
form.BackgroundImageLayout = ImageLayout.Center;
this.TopMost = true;
formOpen = true;
form.Location = new Point(Cursor.Position.X, Cursor.Position.Y);
}
}
private void pictureBox1_MouseLeave(object sender, EventArgs e)
{
//MessageBox.Show("Worked");
}
}
The MouseLeave (and other events) was not recognized because the opening of the popup window and especially making it topmost=true took away the focus from the original form and its PictureBox.
It also didn't move because not code for moving was provided..
Here are a few changes that will make the form move:
You need a reference to it at the form1 level
you need to move it in the MouseMove event
Note that Hover is a once-only type of event. It fires only once until you leave the control.. (Note: Setsu has switched from Hover to Enter. This works fine, but lacks the short delay before showing the 2nd Form. If you want that back you can either switch back to Hover or you can fake the hover delay by a Timer, which is what I often do.)
// class level variable
Form form;
private void Form1_Load(object sender, EventArgs e)
{
pictureBox1.MouseEnter += pictureBox1_MouseEnter;
pictureBox1.MouseLeave +=pictureBox1_MouseLeave;
pictureBox1.MouseMove += pictureBox1_MouseMove; // here we move the form..
}
// .. with a little offset. The exact numbers depend on the cursor shape
void pictureBox1_MouseMove(object sender, MouseEventArgs e)
{
if ((form != null) && form.Visible)
{
form.Location = new Point(Cursor.Position.X + 5, Cursor.Position.Y + 5);
}
}
void pictureBox1_MouseEnter(object sender, EventArgs e)
{
// we create it only once. Could also be done at startup!
if (form == null)
{
form = new Form();
form.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
//form.BackColor = Color.Orchid;
form.Name = "imageForm";
this.AddOwnedForm(form);
form.BackColor = Color.Black;
form.Dock = DockStyle.Fill;
form.Size = new Size(30, 30);
form.BackgroundImageLayout = ImageLayout.Center;
//this.TopMost = true; // wrong! this will steal the focus!!
form.ShowInTaskbar = false;
}
// later we only show and update it..
form.Show();
form.Location = new Point(Cursor.Position.X + 5, Cursor.Position.Y + 5);
// we want the Focus to be on the main form!
Focus();
}
private void pictureBox1_MouseLeave(object sender, EventArgs e)
{
if (form!= null) form.Hide();
}
MouseHover = Occurs when the mouse pointer rests on the control. (msdn)
Try MouseMove instead.
I have an application in C# and using forms, I am placing a label each time I right click on the form. This label can be moved around, re-sized and modified its color.
So far so good, but I want to make a server that will receive everything I do and send this to other clients so they can see everything I do, and also they can do exactly the same things. I have made eventhandlers, but I have no idea how to send the information through the network, or what information to send to update the form for each client.

this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.DrawingSquares_MouseDown);
}
This does the client side of the application, in which you can draw a label and modify its properties. I need some help on how to do the server side, any help is much appreciated, thank you in advance.
