How to update countdown timers in a DataGridView?

I created a DataGridView (Building queue) which can be filled by the user. The user has to insert the time [Textbox H and M] it has to wait. After selecting the buildings and adding them to the queue, the user can press start [Button Start/Stop] and the countdown still start for a maximum of 4 buildings at a time [Textbox named Builders].
Added buildings to the queue:
Pressed Start. 4 countdowns running. 5th one is waiting.
After the first timer hits zero, the row of that timer will be deleted. The program isn't using the right timers. (There was a bit of delay between the screenshots.) The first row has been duplicated. The first row timer has stopped working. and the others are still counting down. But the 5th row, disappeared.
I want the program to be able to continue with the next building countdown whenever one of the four countdowns is finished.
public void TimerFirstRow_Tick(object sender, EventArgs e)
{
if (time0 > 0 && this.dataGridView1.Rows.Count > 0)
{
time0--;
this.dataGridView1.Rows[0].Cells[2].Value = string.Format("00:{0}:{1}", time0 / 60, time0 % 60);
}
else
{
timer_0.Stop();
}
And I think here is the mistake / error, the place of the countdown is hardcoded into the Timer Tick event code.
The start button code:
private void StartButton_Click(object sender, EventArgs e)
{
QueueMax = this.dataGridView1.Rows.Count;
if (MaxBuild.Text == "")
{
label3.Text = "Fill MaxBuilders:";
}
else
{
MaxBuilder = int.Parse(MaxBuild.Text);
}
if (QueueMax >= MaxBuilder)
{
if (!timerB)
{
if (QueueMax > 0)

I recommend using a single timer, and then subtracting the elapsed time from the original Waiting Time. The important code is in the timer_Tick method:

Custom MessageBox with custom-defined Buttons [duplicate]

I am doing C# application, and I want to change the style of a message box. Is it possible or not?
Example: change button style, fore color, etc.

You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings:
FormBorderStyle FixedToolWindow
ShowInTaskBar False
StartPosition CenterScreen
To show it use myNewMessageBoxInstance.ShowDialog();. And add a label and buttons to your form, such as OK and Cancel and set their DialogResults appropriately, i.e. add a button to MyNewMessageBox and call it btnOK. Set the DialogResult property in the property window to DialogResult.OK. When that button is pressed it would return the OK result:
MyNewMessageBox myNewMessageBoxInstance = new MyNewMessageBox();
DialogResult result = myNewMessageBoxInstance.ShowDialog();
if (result == DialogResult.OK)
{
// etc
}
It would be advisable to add your own Show method that takes the text and other options you require:
public DialogResult Show(string text, Color foreColour)
{
lblText.Text = text;
lblText.ForeColor = foreColour;
return this.ShowDialog();
}

MessageBox::Show uses function from user32.dll, and its style is dependent on Windows, so you cannot change it like that, you have to create your own form

Here is the code needed to create your own message box:

How do I properly add a custom control to another custom control so that it will render in a form?

I've created a custom control in C#. A highly-simplified version of it is shown below:
class WellControl : Control
{
Pen circlePen = new Pen(Color.Black, 5);
Brush wellShader = new SolidBrush(Color.BlueViolet);
Brush wellBlanker = new SolidBrush(Color.LightGray);
public WellControl(int wellNum)
{
InitializeComponent();
}
private void DrawWell()
{
using (Graphics well = this.CreateGraphics())
{
this.Size = new Size(WellSize, WellSize);
if (this.selected)
{
well.FillEllipse(wellShader, ellipseCoords);
}
else
{
well.FillEllipse(wellBlanker, ellipseCoords);
}
well.DrawEllipse(circlePen, ellipseCoords);
using (Font wellNumberFont = new Font("Arial", 14, FontStyle.Bold))
{
well.DrawString(WellNum.ToString(), wellNumberFont, Brushes.Black, new Point(13, 13));
}
}
}
private void WellPaintEventHandler(object sender, EventArgs e)
{
DrawWell();
}
private void InitializeComponent()
{
this.SuspendLayout();
this.Paint += new System.Windows.Forms.PaintEventHandler(WellPaintEventHandler);
this.ResumeLayout();
}
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
if (disposing)
{
//dispose all the custom stuff
}
}
}
When I add it to a form, it renders properly (again, simplified example):
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
for (int i = 0; i < 4; i++)
{
WellControl newWell = new WellControl(i + 1);
newWell.Location = new Point(15, 50 * i);
newWell.Size = new System.Drawing.Size(45, 45);
this.Controls.Add(newWell);
}
}
}
I have another custom control, "Plate", which is intended to hold many "Wells". The code intended to draw the wells evenly across the plate probably sucks right now but I'm just trying to see something:
class PlateControl : Control
{
Pen blackPen = new Pen(Color.Black, 3);
public PlateControl()
{
this.Size = new Size(600, 800);
List<WellControl> plateWells = new List<WellControl>();
int column = 1;
int row = 0;
for (int i = 1; i <= 96; i++)
{
column = Convert.ToInt32(Math.Ceiling(Convert.ToDecimal(i / 8)));
row = i % 8;
WellControl newWell = new WellControl(i + 1);
newWell.Name = "wellControl" + i;
newWell.Location = new Point(column * 50, row * 50);
newWell.Size = new System.Drawing.Size(45, 45);
newWell.TabIndex = i;
newWell.WellSize = 45;
plateWells.Add(newWell);
newWell.Visible = true;
}
InitializeComponent();
}
private void InitializeComponent()
{
this.SuspendLayout();
this.Paint += new System.Windows.Forms.PaintEventHandler(PlatePaintEventHandler);
this.ResumeLayout();
}
private void DrawPlate()
{
using (Graphics plate = this.CreateGraphics())
{
Point topLeft = new Point(0, 0);
Point topRight = new Point(600, 0);
Point bottomRight = new Point(600, 400);
Point bottomLeft = new Point(0, 400);
plate.DrawLine(blackPen, topLeft, topRight);
plate.DrawLine(blackPen, topRight, bottomRight);
plate.DrawLine(blackPen, bottomRight, bottomLeft);
plate.DrawLine(blackPen, bottomLeft, topLeft);
}
}
private void PlatePaintEventHandler(object sender, EventArgs e)
{
DrawPlate();
}
}
If I add this control to a Winform using this.Controls.Add(new PlateControl()), the rectangle renders, but not the WellControls I added to the PlateControl in the constructor loop. What am I doing incorrectly?

You need to add List of WallControl to plate control.
public PlateControl()
{
this.Size = new Size(600, 800);
List<WellControl> plateWells = new List<WellControl>();

WPF Mediaelement.Position is not working

What I need is to set the Position property on WPF's MediaElement control. But when I play the video, (either via Play() or through some kind of animation on Opacity) it is is not working at all. It is showing 00:00:00 time, but I would expect it to be set to 00:00:05.
I have hard-coded Position value and it is not working at all.
Just In case I am going to put all my code I have so u can see the whole animation logic.
Any clue?
public partial class CrossFadeTransition : UserControl

Player1.UnloadedBehavior = MediaState.Stop;
Player2.LoadedBehavior = MediaState.Manual;
Player2.UnloadedBehavior = MediaState.Stop;
PlayerPosition = new Dictionary<string, Position2D>();
PlayerPosition.Add("Player1", Position2D.Front);
PlayerPosition.Add("Player2", Position2D.Back);
}

}

positionPlayer2 = PlayerPosition["Player2"];
if (positionPlayer1 == Library.Position2D.Back)
{
Player1.Source = uri;
if (Player1.IsEnabled)
Player1.Stop();
Player1.Position = TimeSpan.FromSeconds(5); // IT IS NOT WORKING !!!
Player1.Play();
}
if (positionPlayer2 == Library.Position2D.Back)
{
Player2.Source = uri;

Player2.Stop();
Player2.Position = TimeSpan.FromSeconds(5); // IT IS NOT WORKING !!!
Player2.Play();
}
_sb1.Children.Clear();
_sb2.Children.Clear();
if (positionPlayer1 == Position2D.Front)
{
_doubleAnimationFrontPlayer.From = 1;
_doubleAnimationFrontPlayer.To = 0;
_doubleAnimationFrontPlayer.Duration = new Duration(Duration);
PlayerPosition["Player1"] = Position2D.Back;
}
else if (positionPlayer1 == Position2D.Back)
{
_doubleAnimationFrontPlayer.From = 0;
_doubleAnimationFrontPlayer.To = 1;
_doubleAnimationFrontPlayer.Duration = new Duration(Duration);
PlayerPosition["Player1"] = Position2D.Front;
}
if (positionPlayer2 == Position2D.Front)
{
_doubleAnimationBackPlayer.From = 1;
_doubleAnimationBackPlayer.To = 0;
_doubleAnimationBackPlayer.Duration = new Duration(Duration);
PlayerPosition["Player2"] = Position2D.Back;
}
else if (positionPlayer2 == Position2D.Back)
{
_doubleAnimationBackPlayer.From = 0;
_doubleAnimationBackPlayer.To = 1;
_doubleAnimationBackPlayer.Duration = new Duration(Duration);
PlayerPosition["Player2"] = Position2D.Front;
}
_sb1.Children.Add(_doubleAnimationFrontPlayer);
Storyboard.SetTargetProperty(_doubleAnimationFrontPlayer, new PropertyPath("(Panel.Opacity)"));
Storyboard.SetTarget(_doubleAnimationFrontPlayer, Player1);
_sb1.Completed += _sb1_Completed;
_sb1.Begin();
//
_sb2.Children.Add(_doubleAnimationBackPlayer);
Storyboard.SetTargetProperty(_doubleAnimationBackPlayer, new PropertyPath("(Panel.Opacity)"));
Storyboard.SetTarget(_doubleAnimationBackPlayer, Player2);
_sb2.Completed += _sb2_Completed;
_sb2.Begin();
}
catch (Exception)
{
throw;
}
}
void _sb2_Completed(object sender, EventArgs e)
{
_sb2.Completed -= _sb2_Completed;
Debug.WriteLine("Player2 COMPLETED " + DateTime.Now.TimeOfDay);
if (positionPlayer2 == Position2D.Front)
{
Player2.Stop();
}
}
void _sb1_Completed(object sender, EventArgs e)
{
_sb1.Completed -= _sb1_Completed;
Debug.WriteLine("Player1 COMPLETED " + DateTime.Now.TimeOfDay);
if (positionPlayer1 == Position2D.Front)
{
Player1.Stop();
}
}
}
I have tried to do like
Player2.Play();
Player2.Pause();
Player2.Position = TimeSpan.FromSeconds(5); // IT IS NOT WORKING !!!
Player2.Play();
But no joy...

I found some solution. It is not completely ideal because sometimes it shows the first video frame, but at least it is working.
We need those events where we can apply new Position.
void Player2_MediaOpened(object sender, RoutedEventArgs e)
{
Player2.Position = new TimeSpan(0, 0, 7);
}
void Player1_MediaOpened(object sender, RoutedEventArgs e)
{
Player1.Position = new TimeSpan(0, 0, 7);
}
We have to close Mediaelement like this.
Player1.Stop();
Player1.Close();
Player1.Source = uri;
Player1.Play();
Have fun! (beer)
