Cannot get Thread and animation Rotation to work

This is my control:
I am getting this to rotate, with this code:
Global variable, bool IsTriangleAnimRunning = false;
And the rest of the code:
public void AnimateTriangle()
{
var rotation = (int)((100 / 100d) * 45 * 1); // Max 45 degree rotation
var duration = (int)(750 * (100 / 100d)); // Max 750ms rotation
while (IsTriangleAnimRunning != false)
{
MyTriangle.Dispatcher.BeginInvoke(
(Action)(() =>
{
var anim = new DoubleAnimation
{
To = rotation,
Duration = new Duration(TimeSpan.FromMilliseconds(duration)),
AutoReverse = true
};
var rt = new RotateTransform();
MyTriangle.RenderTransform = rt;
rt.BeginAnimation(RotateTransform.AngleProperty, anim);
}), DispatcherPriority.ContextIdle);
Thread.Sleep(duration * 2);
}
}
The event handler for the button, that triggers the animation:
public void HandleTriangleEvents(object sender, RoutedEventArgs a)
{
Thread t_triagle = new Thread(new ThreadStart(this.AnimateTriangle));
Button btn = (Button)sender;
if (btn.Name == "btnStartTriangleAnim")
{
IsTriangleAnimRunning = true;
btnStartTriangleAnim.IsEnabled = false;
t_triagle.Start();
}
else
{
IsTriangleAnimRunning = false;
btnStartTriangleAnim.IsEnabled = true;
t_triagle.Abort();
}
}
It behaves in an unatural way, because, when I stop it, it resets to its regular position. I am assuming it, does this for some reason, that I cannot understand. Also, for some reason, this code does not get it to run constantly, but only once.
Desired functionality:
If, I hit start button, run the thread and keep on rotating, while thread is running. If, I hit, stop, then stop in the current state of rotation. If I hit start, run the thread again and keep rotating back and forth.

Tested with Task Async, runs slower and doesn't repeat.
private async Task AnimateTriangle()
{
double rotation = 45d;
double duration = 100d;
var anim = new DoubleAnimation
{
To = rotation,
Duration = TimeSpan.FromMilliseconds(duration),
AutoReverse = true,
RepeatBehavior = RepeatBehavior.Forever
};
var transform = MyTriangle.RenderTransform as RotateTransform;
await Task.Factory.StartNew(() =>
{
while (IsTriangleAnimRunning != false)
{
MyTriangle.Dispatcher.Invoke(() =>
{
if (transform == null)
{
transform = new RotateTransform();
MyTriangle.RenderTransform = transform;
}
transform.BeginAnimation(RotateTransform.AngleProperty, anim);
}, DispatcherPriority.ContextIdle);
if (IsTriangleAnimRunning == false)
{
MyTriangle.Dispatcher.Invoke(() =>
{
if (MyTriangle.RenderTransform is RotateTransform)
{
var angle = transform.Angle; // current animated value
transform.Angle = angle;
transform.BeginAnimation(RotateTransform.AngleProperty, null);
}
}, DispatcherPriority.ContextIdle);
}
}
});
}

You do not need to start a thread.
Start an animation that runs forever, until you reset it by setting a null animation.
Before you reset it, explicitly set the value of the target property to the current animated value.
Reuse the existing RotateTransform instead of re-assigning one each time you start the animation.
private void StartButtonClick(object sender, RoutedEventArgs e)
{
double rotation = 45d;
double duration = 750d;
var anim = new DoubleAnimation
{
To = rotation,
Duration = TimeSpan.FromMilliseconds(duration),
AutoReverse = true,
RepeatBehavior = RepeatBehavior.Forever
};
var transform = MyTriangle.RenderTransform as RotateTransform;
if (transform == null)
{
transform = new RotateTransform();
MyTriangle.RenderTransform = transform;
}
transform.Angle = 0d;
transform.BeginAnimation(RotateTransform.AngleProperty, anim);
}
private void StopButtonClick(object sender, RoutedEventArgs e)
{
if (MyTriangle.RenderTransform is RotateTransform transform)
{
var angle = transform.Angle; // current animated value
transform.Angle = angle;
transform.BeginAnimation(RotateTransform.AngleProperty, null);
}
}

How do I make a timer that changes how many ticks he runs on different occasions?

I'm trying to code a Simon Says game and I ran into a problem. I cannot figure out how to make my Randomizer timer (that randomizes which boxes are lit up) to run by waves. I want it to run once, then when it's referred to again - run twice and so on.
This is RandomPlace():
private PictureBox RandomPlace()
{
PictureBox p = new PictureBox();
Random rnd = new Random();
switch (rnd.Next(1, 5))
{
case 1:
p = TopRight;
break;
case 2:
p = TopLeft;
break;
case 3:
p = BottomRight;
break;
case 4:
p = BottomLeft;
break;
}
return p;
} //Gets a random PictureBox
This is RandomImage():
private void RandomImage()
{
TopLeft.Enabled = false;
TopRight.Enabled = false;
BottomLeft.Enabled = false;
BottomRight.Enabled = false;
PictureBox a = RandomPlace();
if (a == TopLeft)
{
TopLeft.Image = Resources.TopLeftLit;
label1.Text = "TopLeft";
Thread.Sleep(500);
TopLeft.Image = Resources.TopLeft;
label2.Text = "TopLeftAFTERSLEEP";
Thread.Sleep(500);
pattern[patternRightNow] = 1;
patternRightNow++;
}
if (a == TopRight)
{
TopRight.Image = Resources.TopRightLit;
label1.Text = "TopRight";
Thread.Sleep(500);
TopRight.Image = Resources.TopRight;
label2.Text = "TopRightAFTERSLEEP"; //FIGURE OUT HOW TO RESET PICTURE
Thread.Sleep(500);
pattern[patternRightNow] = 2;
patternRightNow++;
}
if (a == BottomLeft)
{
this.BottomLeft.Image = Resources.BottomLeftLit;
label1.Text = "BottomLeft";
Thread.Sleep(500);
this.BottomLeft.Image = Resources.BottomLeft;
label2.Text = "BottomLeftAFTERSLEEP";
Thread.Sleep(500);
pattern[patternRightNow] = 3;
patternRightNow++;
}
if (a == BottomRight)
{
this.BottomRight.Image = Resources.BottomRightLit;
label1.Text = "BottomRight";
Thread.Sleep(500);
this.BottomRight.Image = Resources.BottomRight;
label2.Text = "BottomRightAFTERSLEEP";
Thread.Sleep(500);
pattern[patternRightNow] = 4;
patternRightNow++;
}
} //Lits up the random PictureBoxes and sets them back to normal
This is Randomizer_Tick():
rivate void Randomizer_Tick(object sender, EventArgs e)
{
RandomImage();
patternRightNow = 0;
tickCount++;
Randomizer.Stop();
ClickCheck();
} //Use RandomImage() to lit up random PictureBoxes on 5 waves, wave 1 - 1 PictureBox, wave 2 - 2 PictureBoxes and so on.
This is ClickCheck():
private void ClickCheck()
{
TopLeft.Enabled = true;
TopRight.Enabled = true;
BottomLeft.Enabled = true;
BottomRight.Enabled = true;
if (tickCount == clickCount)
{
CheckIfWin();
Randomizer.Start();
}
} //Enables the PictureBoxes to be pressed, after the user input reaches the current wave's amount of PictureBoxes lit up, disable PictureBoxes again and start the randomizer

Instead of using timers, I advise you to look at Tasks. It's much easier to create such statemachines.
Fill a list with colors and play it. Wait until the user pressed enough buttons and check the results.
For example: (haven't tested it, it's just for example/pseudo code)
It might contain some typo's.
private List<int> _sequence = new List<int>();
private List<int> _userInput = new List<int>();
private Random _rnd = new Random(DataTime.UtcNow.Milliseconds);
private bool _running = true;
private bool _inputEnabled = false;
private TaskCompletionSource<object> _userInputReady;
public async void ButtonStart_Click(object sender, EventArgs e)
{
if(_running)
return;
while(_running)
{
// add a color/button
_sequence.Add(_rnd.Next(4));
// play the sequence
for(int color in _sequence)
{
// light-up your image, whatever
Console.WriteLine(color);
// wait here...
await Task.Delay(300);
// turn-off your image, whatever
}
// clear userinput
_userInput.Clear();
_userInputReady = new TaskCompletionSource<object>();
_inputEnabled = true;
// wait for user input.
await _userInputReady.Task;
// compare the user input to the sequence.
for(int i=0;i<_sequence.Count;i++)
{
if(_sequence[i] != _userInput[i])
{
_running = false;
break;
}
}
}
Console.WriteLine("Not correct");
}
// one handler for all buttons. Use the .Tag property to store 0, 1, 2, 3
public void ButtonClick(object sender, EventArgs e)
{
if(!_inputEnabled)
return;
var button = (Button)sender;
// add user input to the queue
_userInput.Add((int)button.Tag);
if(_userInput.Count >= _sequence.Count)
_userInputReady.SetResult(null);
}

How to Pass and Set values to Usercontrol in wpf

How to Pass and Set values to Usercontrol.
Here I have two question regarding a WPF project.
Overview:
In this project, I'm trying to use a Usercontrol as a resources on a canvas and connecting them with each other by LineGeometry. 'MyThumb' class i'm using to make control dragable and control set values.
where i'm using overrided 'OnApplyTemplate' method to pass values on the Usercontrol. To set value i'm using 'Template.FindName'. Here it is returning null.
Now the question is 'how to set values on usercontrol' in the code below:
Another question is related to line color. In the project i'm using LineGeometry to display lines between usercontrols but not able to change line colors.. want to set different lines with different color.
Here the question is how to change color of existing LineGeometry.
Please have a look to the codes i'm using:

Trying to make a custom print class where the application tells when to print a page

I'm building a series of apps for my place of business so I'm trying to create my own printing class that I can refer to for all of my applications.
The issue is, I'm trying to figure out a way for the application to tell the class when to print the page, and I am unable to find a way to do so.
For example, this is what I have so far:
// Report Variables
private bool bPrinting = false;
private int iPage = 0;
private float fOverflow = 0.00F;
private string sPrintLine = null;
private Font fontTmpFont = null;
private PrintPageEventArgs ppeaEv = null;
private Margins mMargins = new System.Drawing.Printing.Margins(25, 25, 25, 25); // Set wide margins
// Clear the print line
public void LineClear()
{
sPrintLine = null;
}
// Insert a string into the print line at the specified position within the line
public void LineInsert(string _InsertString, int _InsertPosition)
{
if (sPrintLine.Length <= _InsertPosition)
sPrintLine = sPrintLine.PadLeft(_InsertPosition) + _InsertString;
else if (sPrintLine.Length <= (_InsertPosition + _InsertString.Length))
sPrintLine = sPrintLine.Substring(0, _InsertPosition) + _InsertString;
else
sPrintLine = sPrintLine.Substring(0, _InsertPosition) + _InsertString + sPrintLine.Substring(_InsertPosition + _InsertString.Length);
}
// Check to see if the line we're trying to print is at the end of the page
public bool AtEndOfPage()
{
return AtEndOfPage(new Font("Courier", 10));
}
public bool AtEndOfPage(Font _Font)
{
if ((fOverflow + _Font.GetHeight(ppeaEv.Graphics)) > ppeaEv.MarginBounds.Height)
return true;
else
return false;
}
// Attempt to print the line
public void LinePrint()
{
LinePrint(null, null);
}
public void LinePrint(Font _Font)
{
LinePrint(_Font, null);
}
public void LinePrint(Font _Font, Brush _Color)
{
if (_Font == null)
_Font = new Font("Courier", 10);
if (_Color == null)
_Color = Brushes.Black;
ppeaEv.Graphics.DrawString(sPrintLine, _Font, _Color,
ppeaEv.MarginBounds.Left, ppeaEv.MarginBounds.Top + fOverflow,
new StringFormat()); // 'Draw' line on page
fOverflow += _Font.GetHeight(ppeaEv.Graphics);
}
// We are done with the report, tell the Print Service to finish up
public void EndReport()
{
ppeaEv.HasMorePages = false;
}
// This is what gets called when the user clicks on 'Print'
private void Print_Click(object sender, EventArgs e)
{
PrintDocument printDocument = new PrintDocument();
printDocument.DefaultPageSettings.Margins = mMargins; // Set margins for pages
printDocument.DefaultPageSettings.Landscape = false; // Set Portrait mode
printDocument.BeginPrint += new PrintEventHandler(printDocument_BeginPrint);
printDocument.EndPrint += new PrintEventHandler(printDocument_EndPrint);
PrintDialog printDialog = new PrintDialog();
printDialog.Document = printDocument; // Set the Document for this print dialog
printDialog.AllowSomePages = true; // Allow the user to select only some pages to print
printDialog.ShowHelp = true; // Allow help button
DialogResult result = printDialog.ShowDialog();
if (result == DialogResult.OK)
{
printDocument.Print(); // Raises PrintPage event
}
printDocument.Dispose();
printDialog.Dispose();
}
void printDocument_BeginPrint(object sender, PrintEventArgs e)
{
iPage = 0;
fOverflow = 0.00F;
}
void printDocument_EndPrint(object sender, PrintEventArgs e)
{
}
As you may be able to tell, I'm trying to fill the page externally to the class, and then have the app tell the class when to print the page when "AtEndOfPage"
I know about "printDocument.PrintPage", but that doesn't seem to be what I need; It builds the page internal to the method and then prints it. I'm not going to be building the print page within that method.
I also am trying to allow for multiple fonts on a single page.
Is there a way to do this?
Thank you all in advance,
Robert

next step i make is makes the media player can be play videooutput.mp4. in here, to make it play, it first must load the video then played. well, this is for the second step. it works well too. here's my code.
private void button6_Click_1(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
// create video source
FileVideoSource fileSource = new FileVideoSource(openFileDialog1.FileName);
// open it
OpenVideoSource(fileSource);
}
}
// Open video source
private void OpenVideoSource(IVideoSource source)
{
// set busy cursor
this.Cursor = Cursors.WaitCursor;
// stop current video source
CloseCurrentVideoSource();
// start new video source
videoSourcePlayer.VideoSource = source;
videoSourcePlayer.Start();
// reset stop watch
stopWatch = null;
// start timer
videoTimer.Start();
this.Cursor = Cursors.Default;
}
// New frame received by the player
private void videoSourcePlayer_NewFrame(object sender, ref Bitmap image)
{
DateTime now = DateTime.Now;
Graphics g = Graphics.FromImage(image);
// paint current time
SolidBrush brush = new SolidBrush(Color.Red);
g.DrawString(now.ToString(), this.Font, brush, new PointF(5, 5));
brush.Dispose();
g.Dispose();
}
// Close video source if it is running
private void CloseCurrentVideoSource()
{
if (videoSourcePlayer.VideoSource != null)
{
videoSourcePlayer.SignalToStop();
// wait ~ 3 seconds
for (int i = 0; i < 30; i++)
{
if (!videoSourcePlayer.IsRunning)
break;
System.Threading.Thread.Sleep(100);
}
if (videoSourcePlayer.IsRunning)
{
videoSourcePlayer.Stop();
}
videoSourcePlayer.VideoSource = null;
}

im using AForge for the media player in c#. All i did is adding the reference of AForge.Controls, AForge.Video and AForge.Video.DirectShow.
now, what i need to do is sending the media data to the media player(c#) byte by byte. i dont have a clue how to make this happen. i also found sample coding IP camera android which it bring the video to the server. however, i still dont have a clue to do it in my apps.
note that the gsm will require number phone of the simcard used and also port number of the modem gsm.
can anybody help me with this. or perhaps giving me some idea on modifying the code. any helps is appreciated. thanks for advance.
