I have been trying to create a chess strategy application. I seem to be having issues with trying to get the label1 control to populate during run time. I am actually pretty new to the idea of dynamically creating events like 'mouse enter, mouse leave' How do I get the label to show the coordinates in the mouse enter event
int currentXposition, currentYposition;
const string positionLabel = "Current Position: ";
private void Test_Load(object sender, EventArgs a)
{
var temp=Color.Transparent; //Used to store the old color name of the panels before mouse events
var colorName = Color.Red; //Color used to highlight panel when mouse over
int numBlocks = 8; //Used to hold the number of blocks per row
int blockSize=70;
//Initialize new array of Panels new
string[,] Position = new string[8, 8];
Panel[,] chessBoardPanels = new Panel[numBlocks, numBlocks];
string Alphabet = "A,B,C,D,E,F,G,H";
string Numbers ="1,2,3,4,5,6,7,8";
string[] alphaStrings = Numbers.Split(',');
string[] numStrings=Numbers.Split(',');
// b = sub[0];
int FirstValue, SecondValue;
//Store Position Values
for (int firstValue = 0; firstValue < 8; ++firstValue)
{
FirstValue = Alphabet[firstValue];
for (int SecValue = 0; SecValue < 8; ++SecValue)
{
SecondValue = Numbers[SecValue];
Position[firstValue, SecValue] = alphaStrings[firstValue] + numStrings[SecValue];
}
}
//Loop to create panels
for (int iRow = 0; iRow < numBlocks; iRow++)
for (int iColumn = 0; iColumn < numBlocks; iColumn++)
{
Panel p = new Panel();
//set size
p.Size = new Size(blockSize, blockSize);
//set back colour
p.BackColor = (iRow + (iColumn % 2)) % 2 == 0 ? Color.Black : Color.White;
//set location
p.Location = new Point(blockSize *iRow+15, blockSize * iColumn+15);
chessBoardPanels[iRow, iColumn] = p;
chessBoardPanels[iRow,iColumn].MouseEnter += (s,e) =>
{
currentXposition = iRow;
currentYposition = iColumn;
var oldColor = (s as Panel).BackColor;
(s as Panel).BackColor = colorName;
temp = oldColor;
label1.Text = Position[iRow, iColumn];
};
chessBoardPanels[iRow, iColumn].MouseLeave += (s, e) =>
{
(s as Panel).BackColor = temp;
};
groupBox1.Controls.Add(p);
}
}
Try this.. It was not populating because of a out of range.. iRow always = 8...
Add this class to your project.
public class ChessSquare
{
public string Letter { get; set; }
public int Number { get; set; }
public Color Color { get; set; }
public string Position
{
get { return string.Format("{0}{1}", Letter, Number); }
}
public ChessSquare()
{
}
public ChessSquare(string letter, int number)
{
Letter = letter;
Number = number;
}
}
Replace the FormLoad method with this:
int blockSize = 20;
Panel[,] chessBoardPanels = new Panel[8, 8];
for (int i = 0; i < 8; i++)
{
for (int j = 0; j < 8; j++)
{
ChessSquare sq = new ChessSquare(((char)(65+i)).ToString(), j);
sq.Color = (i + (j % 2)) % 2 == 0 ? Color.AliceBlue : Color.White;
Panel p = new Panel()
{ Size = new Size(blockSize, blockSize),
BackColor = sq.Color,
Tag = sq,
Location = new Point(blockSize * i + 15, blockSize * j+15),
};
p.MouseEnter+=new EventHandler(squareMouseEnter);
p.MouseLeave += new EventHandler(squareMouseLeave);
chessBoardPanels[i, j] = p;
groupBox1.Controls.Add(p);
}
}
And add those two methods to your code:
void squareMouseEnter(object sender, EventArgs e)
{
Panel p = (Panel)sender;
ChessSquare sq = (ChessSquare)p.Tag;
p.BackColor = Color.Aqua;
label1.Text = string.Format("Current position: {0}", sq.Position);
}
void squareMouseLeave(object sender, EventArgs e)
{
Panel p = (Panel) sender;
ChessSquare sq = (ChessSquare)p.Tag;
p.BackColor = sq.Color;
}
I there are several ways of doing it... This one is pretty straight forward.

So i am trying to grab user input from my text boxes which are being printed to the screen through a loop and if Statements. When trying to print the values put into the textbox I only get one value. Here is the code for adding the textboxes to the grid:
private void InsertEasyNums()
{
int x = 70;
int y = 40;
for (int i = 0; i < 9; i++)
{
if (i == 3)
{
x = 70;
y = 160;
}
else if(i == 6)
{
x = 65;
y = 280;
}
if (easyNums[i] == '0')
{
DrawingField.SendToBack();
int panelX = x + 300;
int panelY = y + + 100;
Font newFont = new Font("Arial", 25);
Point tbLocation = new Point(panelX, panelY);
userInput[i] = new TextBox();
userInput[i].Name = "Row[i]TB";
userInput[i].Font = newFont;
userInput[i].Width = 50;
userInput[i].Location = tbLocation;
userInput[i].BorderStyle = BorderStyle.None;
userInput[i].BackColor = DefaultBackColor;
Controls.Add(userInput[i]);
DrawingField.SendToBack();
x = x + 145;
DrawingField.SendToBack();
}
else if (easyNums[i] != '0')
{
DrawingField.SendToBack();
Font drawFont = new Font("Arial", 30, FontStyle.Bold);
Brush Numbers = new SolidBrush(Color.Black);
Graphics g = DrawingField.CreateGraphics();
g.DrawString(Convert.ToString(easyNums[i]), drawFont,
Numbers, x, y);
x = x + 146;
}
}
}
Here is where I try to print the Textboxes:
foreach (Control c in DrawingField.Controls)
{
if (c is TextBox)
{
int i = 0;
TextBox txt = (TextBox)c;
string str = txt.Text;
TBValues[i] = str;
i++;
}
}
foreach (var key in TBValues)
{
MessageBox.Show(key);
}
ANSWER: I moved the declaration of userInput to the beginning of the method and looped through 9 time to give 9 textboxes then used the if statements to move them and change properties.
try to move i before the loop
int i = 0;
foreach (Control c in DrawingField.Controls)
{
if (c is TextBox)
{
TextBox txt = (TextBox)c;
string str = txt.Text;
TBValues[i] = str;
i++;
}
}
foreach (var key in TBValues)
{
MessageBox.Show(key);
}
I'm creating a new Picturebox via code, but now my TextBoxes don't give me any values. I think they went out of focus, or their controls aren't working anymore, here's the code so far:
private void button1_Click(object sender, EventArgs e)
{
int ErrorCode = 0;
string NewName = NewPointName.Text;
int X, Y;
Application.DoEvents();
if (NewPointName.Text == "")
ErrorCode = 1;
else
for (int i = 0; i < Names + 1; i++)
{
if (PointName[i] == NewName)
ErrorCode = 2;
}
if (ErrorCode > 0)
MessageBox.Show("Error " + ErrorCode);
else
{
if (Convert.ToInt32(NewPointXBox.Text) > 60)
X = 60;
else if (Convert.ToInt32(NewPointXBox.Text) < -60)
X = -60;
else if (NewPointXBox.Text == "")
X = 0;
else
X = Convert.ToInt32(NewPointXBox.Text);
if (Convert.ToInt32(NewPointYBox.Text) > 60)
Y = 60;
else if (Convert.ToInt32(NewPointYBox.Text) < -60)
Y = -60;
else if (NewPointYBox.Text == "")
Y = 0;
else
Y = Convert.ToInt32(NewPointYBox.Text);
Punkt.GiveName(NewName, Names);
Punkt.GiveCoordinates(X, Y, Names);
PointName[Names] = NewName;
NewPointName.Text = "";
NewPointXBox.Text = "";
NewPointYBox.Text = "";
Application.DoEvents();
UpdatePoint();
CreatePoint(X, Y, NewName, Names);
Names++;
ErrorCode = 0;
NewName = "";
}
}
public void CreatePoint(int X, int Y, string name, int i)
{
int StartPointX = 450, StartPointY = 450, Factor = 7;
if (RadioG6060.Checked)
{
StartPointX = 454;
StartPointY = 449;
Factor = 7;
}
Dot[i] = new PictureBox();
this.Controls.Add(Dot[i]);
Dot[i].Name = "PB_" + name;
Dot[i].Size = new Size(10, 10);
Dot[i].Image = Image.FromFile("../Dot.png");
Dot[i].Anchor = AnchorStyles.Left;
Dot[i].Location = new Point(StartPointX, StartPointY);
Dot[i].Visible = true;
InitializeComponent();
Dot[i].BringToFront();
Dot[i].Location = new Point(Dot[i].Location.X + (X * Factor), Dot[i].Location.Y - (Y * Factor));
Application.DoEvents();
}
I think it's the this.controls.Add(Dot[i]) that throws it off, because now I can't access the text in my NewPointName textbox.
How can I focus the program back on the form or do generally anything that could activate the boxes again?
I just solved the problem, I just had to leave out the InitializeComponent(), then it worked. Turns out that if you do that, the already existing components get blocked and can't be changed in any options of themselves anymore.
I am taking input from 5 textboxes and sorting the values inserted into the text boxes by putting them into labels and moving the labels around till the values in them are sorted.
I have so far put them into labels, but I don't know how to move he labels on button click and let the labels move to get sorted.
This is one way of simulating the algorithm of insertion sort.
my code so far for button click :
private void button1_Click(object sender, EventArgs e)
{
if (comboBox1.SelectedItem.ToString() == "insertion sort")
{
for ( i = 0; i < 5; i++)
{
if (c != 0)
{
myLabel[i].Dispose();
}
myLabel[i] = new Label();
myLabel[i].Location = new Point(a, b);
myLabel[i].Width = 70;
myLabel[i].Height = 70;
myLabel[i].BackColor=Color.White;
myLabel[i].BorderStyle = BorderStyle.FixedSingle;
panel1.Controls.Add(myLabel[i]);
a = a + 100;
myLabel[i].Visible = true;
}
timer1.Start();
c++;
}
myLabel[0].Text = textBox1.Text;
myLabel[1].Text = textBox5.Text;
myLabel[2].Text = textBox4.Text;
myLabel[3].Text = textBox3.Text;
myLabel[4].Text = textBox2.Text;
}
public partial class Form1 : Form
{
Label[] myLabel=new Label[5];
int a = 30; //x coordinates of first label in label1 array
int b = 125; //y coordinates of first label in label1 array
int c = 0;
int k = 0;
int n = 0;
int j = 1;
int i;
public Form1()
{
InitializeComponent();
comboBox1.Items.Add("Selection Sort");
comboBox1.Items.Add("Insertion Sort");
}
you need to sort value of textbox and then put value in labels. Something like this :
private void button1_Click(object sender, EventArgs e)
{
if (comboBox1.SelectedItem.ToString() == "insertion sort")
{
for ( i = 0; i < 5; i++)
{
if (c != 0)
{
myLabel[i].Dispose();
}
myLabel[i] = new Label();
myLabel[i].Location = new Point(a, b);
myLabel[i].Width = 70;
myLabel[i].Height = 70;
myLabel[i].BackColor=Color.White;
myLabel[i].BorderStyle = BorderStyle.FixedSingle;
panel1.Controls.Add(myLabel[i]);
a = a + 100;
myLabel[i].Visible = true;
}
timer1.Start();
c++;
}
var list = new List<KeyValuePair<string, string>>();
list.Add(new KeyValuePair<string, string>(textBox1.Text, textBox1.Text.Value));
list.Add(new KeyValuePair<string, string>(textBox2.Text, textBox2.Text.Value));
list.Add(new KeyValuePair<string, string>(textBox3.Text, textBox3.Text.Value));
list.Add(new KeyValuePair<string, string>(textBox4.Text, textBox4.Text.Value));
list.Add(new KeyValuePair<string, string>(textBox5.Text, textBox5.Text.Value));
list.Sort(Compare2);
int increment = 0;
foreach(var item in list)
{
myLabel[increment].Text=item.Value;
increment++;
}
}
static int Compare2(KeyValuePair<string, string> a, KeyValuePair<string, string> b)
{
return a.Value.CompareTo(b.Value);
}
When I run the following code, it populates the label1 control one time. Then the label1 control does nothing else. How do I get the label1 control to change on the mouse enter events. Please provide code examples.
int currentXposition, currentYposition;
const string positionLabel = "Current Position: ";
private void Test_Load(object sender, EventArgs a)
{
var temp=Color.Transparent; //Used to store the old color name of the panels before mouse events
var colorName = Color.Red; //Color used to highlight panel when mouse over
int numBlocks = 8; //Used to hold the number of blocks per row
int blockSize=70;
//Initialize new array of Panels new
string[,] Position = new string[8, 8];
Panel[,] chessBoardPanels = new Panel[numBlocks, numBlocks];
string Alphabet = "A,B,C,D,E,F,G,H";
string Numbers ="1,2,3,4,5,6,7,8";
string[] alphaStrings = Alphabet.Split(',');
string[] numStrings=Numbers.Split(',');
// b = sub[0];
int FirstValue, SecondValue;
//Store Position Values
for (int firstValue = 0; firstValue < 8; ++firstValue)
{
FirstValue = Alphabet[firstValue];
for (int SecValue = 0; SecValue < 8; ++SecValue)
{
SecondValue = Numbers[SecValue];
Position[firstValue, SecValue] = alphaStrings[firstValue] + numStrings[SecValue];
}
}
//Loop to create panels
for (int iRow = 0; iRow < numBlocks; iRow++)
{
for (int iColumn = 0; iColumn < numBlocks; iColumn++)
{
Panel p = new Panel();
//set size
p.Size = new Size(blockSize, blockSize);
//set back colour
p.BackColor = (iRow + (iColumn % 2)) % 2 == 0 ? Color.Black : Color.White;
//set location
p.Location = new Point(blockSize *iRow+15, blockSize * iColumn+15);
chessBoardPanels[iRow, iColumn] = p;
chessBoardPanels[iRow,iColumn].MouseEnter += (s,e) =>
{
currentXposition = iRow;
currentYposition = iColumn;
var oldColor = (s as Panel).BackColor;
(s as Panel).BackColor = colorName;
temp = oldColor;
label1.Text = Position[iRow, iColumn];
};
chessBoardPanels[iRow, iColumn].MouseLeave += (s, e) => {
(s as Panel).BackColor = temp;
};
groupBox1.Controls.Add(p);
}
}
}
I'm answering this only because I think it's important to show what happens when scope is confused. The reason you're having your issue is the scope of your variables. Your label is changing iRow * iColumn times, but only during initial execution. From then on, iRow and iColumn are fixed at their final values.
To achieve your desired end goal, it'd be easiest to create an extension of Panel:
public class ChessPanel : Panel {
private const Color HighlightColor = Color.Red;
public int iColumn { get; set; }
public int iRow { get; set; }
public Color PrimaryColor { get; set; }
public ChessPanel() : base()
{
this.MouseEnter += (s,e) =>
{
this.PrimaryColor = this.BackColor;
this.BackColor = HighlightColor;
};
this.MouseLeave += (s,e) =>
{
this.BackColor = this.PrimaryColor;
};
}
}
This will then allow you to reduce your code as follows:
int currentXposition, currentYposition;
const string positionLabel = "Current Position: ";
private void Test_Load(object sender, EventArgs a)
{
var temp=Color.Transparent; //Used to store the old color name of the panels before mouse events
var colorName = Color.Red; //Color used to highlight panel when mouse over
int numBlocks = 8; //Used to hold the number of blocks per row
int blockSize=70;
//Initialize new array of Panels new
string[,] Position = new string[8, 8];
ChessPanel[,] chessBoardPanels = new ChessPanel[numBlocks, numBlocks];
string Alphabet = "A,B,C,D,E,F,G,H";
string Numbers ="1,2,3,4,5,6,7,8";
string[] alphaStrings = Alphabet.Split(',');
string[] numStrings=Numbers.Split(',');
int FirstValue, SecondValue;
//Store Position Values --- no idea what this is supposed to do...
for (int firstValue = 0; firstValue < 8; ++firstValue)
{
FirstValue = Alphabet[firstValue];
for (int SecValue = 0; SecValue < 8; ++SecValue)
{
SecondValue = Numbers[SecValue];
Position[firstValue, SecValue] = alphaStrings[firstValue] + numStrings[SecValue];
}
}
//Loop to create panels
for (int iRow = 0; iRow < numBlocks; iRow++)
{
for (int iColumn = 0; iColumn < numBlocks; iColumn++)
{
ChessPanel p = new ChessPanel();
//set size
p.Size = new Size(blockSize, blockSize);
//set back colour
p.BackColor = (iRow + (iColumn % 2)) % 2 == 0 ? Color.Black : Color.White;
//set location
p.Location = new Point(blockSize *iRow+15, blockSize * iColumn+15);
p.MouseEnter += (s,e) =>
{
var cpSelf = s as ChessPanel;
if (cpSelf != null)
{
label1.Text = Position[cpSelf.iRow, cpSelf.iColumn];
}
};
groupBox1.Controls.Add(p);
chessBoardPanels[iRow, iColumn] = p;
}
}
}
I'm assuming you're making use of many of those variables later on int the program, and looking at this kind of makes my head hurt, so I left most of it in place.
Delegates are a very powerful and useful utility, but they can cause confusion with variable scope. Be very careful when using these, and make sure you treat them as functional units that execute later and can therefore only rely on the state of the program at execution of the block rather than at creation of the block. If you notice, I kept the reference to the Position array simply to show that you can still access local variables within the scope of the delegate because it is technically still in scope. Structurally, this could easily be moved into the ChessPanel class and referenced 100% locally. This example should be used as a caution as it can show how a "local" variable that many people assume are garbage-collected at end of function execution can hang around and eat up memory.
This code is untested and may have minor syntax errors. Hopefully the spirit of the structure is understood.
I am using file watcher monitoring the file output, and then dynamically display the results using d3 (dynamic data display). Here is more details:
Data are series of tiff file generated one by one quickly (20-25 miliseconds per file generation);
Once there is a file coming in, event is fired, and the file is processed (some stats calculation);
The results will be sent to a d3 plotter, which will dynamically display the results on a charter.
When I close the d3 charter window, the file watcher catcher pretty much all the events, but here is my problem:
However, when I leave the d3 charter window open, even when there is not any stats calculation, the file watcher drop many events (some big gap occurs).
Here is what we have tried:
Increase the watcher buffer, but, it still drop events as long as the d3 charter window is open.
Using C++ dll to calculate stats, but it looks even more slow.
So I am wondering:
Do d3 plotter and file watcher conflict/interfere with each other?
Can I possibly use them together to to real time plot?
Is there anyway to get around my problem?
Any pointers are appreciated.
Here is the code for d3 plotter, including constructor, plotter initiator, and plotter update:

Here is how files are monitored:
Where events (file written) are filed
void tiffWatcher_EventChanged(object sender, WatcherExEventArgs e)
{
string fileName = ((FileSystemEventArgs)(e.Arguments)).FullPath;
string fileExt = StringExtension.GetLast(fileName, 4);
if (!IsFileLocked(fileName))
{
Action EventFinished = delegate()
{
CreateListViewItem(fileName, "Finished", DateTime.Now.ToString("HH:mm:ss.fff"));
};
listView1.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, EventFinished);
_tiffName.Add( fileName);
_tiffFilledCount++;
}
}
tiff data processing, and data communication to d3 plotter:
void tiffTimer_Tick(object sender, EventArgs e)
{
//throw new NotImplementedException();
byte[] image = new byte[_signalManager.ImgWidth * _signalManager.ImgHeight];
if (_tiffFilledCount - _tiffProcessedCount >= 1)
{
string fileName = _tiffName[_tiffProcessedCount++];
char filePre = fileName[49];
int indexBeigin = fileName.LastIndexOf("_");
int indexEnd = fileName.LastIndexOf(".");
_signalIndex = Convert.ToInt32(fileName.Substring(indexBeigin + 1, indexEnd - indexBeigin - 1)) - 1; // 0 based//
_deltaT = ExtractTiffDeltaT(fileName, "DeltaT=", 1);
_channelIndex = (int)Enum.Parse(typeof(ChannelList), Convert.ToString(filePre));
TIFFIImageIO.LoadTIFF(fileName, ref image);
_signalManager.Image = image;
for (int i = 0; i < _nActiveStatsOneChannel; i++)
{
_signalManager.GetSignal( _signalDisplay.StatsEnableIndex[i], ref _signal);
UpdateSignal(_channelIndex, i, _tiffProcessedCount-1, _deltaT, _signal);
}
// if( _tiffProcessedCount % 5 == 0)
_signalDisplay.SetData(_XList, _YList, true);
}
}
I use a Timer.Tick to process the file every 50-100 miliseconds, still testing.
The way I handled it was to setup a Timer, cyclically handling calculation, display. So far, it works fine. Of course there will be many events are missing, but we handle large amount of points (thousands of them), so it is OK to hundreds to do the plot. Here is the code:
private Timer _tiffTimer;
void Window1_Loaded(object sender, RoutedEventArgs e)
{
//throw new NotImplementedException();
_tiffTimer = new Timer();
_tiffTimer.Interval = 50; // change interval to change performance
_tiffTimer.Tick += new EventHandler(tiffTimer_Tick);
_tiffTimer.Start();
}
void tiffTimer_Tick(object sender, EventArgs e)
{
//do your stuff here
}
