I am wirting a super simple file, get the data from arduino though serial ports, and than if i get data, first i log them in a txt file, and then I need to send them into a database for future calculation. therefore I installed the SQLite, and write caode in this, but when i test it, I can log data to txt fime, but nothing in my database.
I set up a database named logging_data, and the table is Logging_data_2, when I find I cant log any data to database, i just let the time be 'a', number be 1,but it still doesnt work. ask for help, thankyou!
I need to plot data from sensors of pH, Temperature and Humidity, the data is sent as a matrix from arduino to PC through the serial port.
I can show the data in a TextBox, but when I try to plot the data, it doesn't work (I don't know how to do it).
I just can plot the data when is not a matrix and it's data from just one sensor.

Let's assume you have prepared your chart, maybe like this:
chart1.Series.Clear();
chart1.Series.Add("ph");
chart1.Series.Add("Temp");
chart1.Series.Add("Hum");
chart1.Series["ph"].ChartType = SeriesChartType.Line;
chart1.Series["Temp"].ChartType = SeriesChartType.Line;
chart1.Series["Hum"].ChartType = SeriesChartType.Line;
chart1.ChartAreas[0].AxisY2.Enabled = AxisEnabled.True;
chart1.ChartAreas[0].AxisY2.Title = "Temp";
chart1.ChartAreas[0].AxisY2.Maximum = 100;
Now you can add a string that contains some data blocks as shown in the comments..
string data = "7.5 23.8 67 \n8.5 23.1 72 \n7.0 25.8 66 \n";
..like this:
var dataBlocks = data.Split('\n');
foreach (var block in dataBlocks)
{
var numbers = block.Split(new [] {' '}, StringSplitOptions.RemoveEmptyEntries);
// rt += someTime; (*)
for (int i = 0; i < numbers.Length; i++)
{
double n = double.NaN;
bool ok = double.TryParse(numbers[i], out n);
if (ok) chart1.Series[i].Points.AddXY(rt, n);
else
{
int p = chart1.Series[i].Points.AddXY(rt, 0);
chart1.Series[i].Points[p].IsEmpty = true;
Console.WriteLine("some error message..");
}
}
}
I have modified the data a little to show the changes a little better..
Note that I left out the counting up of your timer rt, which is why the chart shows the points with indexed x-values. For a real realtime plot do include it maybe here (*) !
If you keep adding data your chart will soon get rather crowded.
You will then either have to remove older data from the beginning or at least set a minimum and maximum x-values to restrict the display to a reasonably number of data points and or turn on zooming!
See here here and here for some examples and discussions of these things!
I am using a DataGridView inner DateTimePicker, but it is not working properly.
It can only select the year or month and the calendar control is closed.
How do I to select the year & month & date?
Try this code (c# code)
DateTimePicker dtp = new DateTimePicker(); //DateTimePicker
Rectangle _Rectangle;
public Form2()
{
InitializeComponent();
dataGridView2.Controls.Add(dtp);
dtp.Visible = false; //
dtp.Format = DateTimePickerFormat.Custom; //2010-08-05
dtp.TextChanged += new EventHandler(dtp_TextChange);
}
private void dataGridView2_CellClick(object sender, DataGridViewCellEventArgs e)
{
switch (dataGridView2.Columns[e.ColumnIndex].Name)
{
case "dateAchatDataGridViewTextBoxColumn1":
_Rectangle = dataGridView2.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true); //
dtp.Size = new Size(_Rectangle.Width, _Rectangle.Height); //
dtp.Location = new Point(_Rectangle.X, _Rectangle.Y); //
dtp.Visible = true;
break;
}
}
private void dtp_TextChange(object sender, EventArgs e)
{
dataGridView2.CurrentCell.Value = dtp.Text.ToString();
}
private void dataGridView2_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e)
{
dtp.Visible = false;
}
private void dataGridView2_Scroll(object sender, ScrollEventArgs e)
{
dtp.Visible = false;
}
This is answer:
public partial class Form1 : Form
{
private DateTimePicker cellDateTimePicker = new DateTimePicker();
DateTimePicker[] sp = new DateTimePicker[100];
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
DataTable dt=new DataTable();
dt.Columns.Add(new DataColumn("Start-Date", typeof(DateTime)));
dataGridView1.DataSource = dt;
}
private void dataGridView1_CellBeginEdit(object sender, DataGridViewCellCancelEventArgs e)
{
sp[e.RowIndex] = new DateTimePicker();
if (dataGridView1.Columns[e.ColumnIndex].Name == "Start-Date")
{
this.cellDateTimePicker = sp[e.RowIndex];
this.cellDateTimePicker.Format = DateTimePickerFormat.Time;
this.cellDateTimePicker.Name = "sp[" + e.RowIndex + "]";
// this.cellDateTimePicker.ValueChanged += new EventHandler(cellDateTimePickerValueChanged);
this.cellDateTimePicker.Visible = true;
this.cellDateTimePicker.CustomFormat = "dd/MM/yyyy";
this.cellDateTimePicker.Format = DateTimePickerFormat.Custom;
this.dataGridView1.Controls.Add(cellDateTimePicker);
System.Drawing.Rectangle tempRect = this.dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);
cellDateTimePicker.Location = tempRect.Location;
cellDateTimePicker.Width = tempRect.Width;
dataGridView1.Columns[0].DefaultCellStyle.Format = "MM'/'dd'/'yyyy";
this.cellDateTimePicker.Visible = true;
}
}
}
Okay so I'm trying to display multiple values in hashtable through my button. But it keeps on showing me the first value but not the others.
public Form1()
{
InitializeComponent();
}
Hashtable Info = new Hashtable();
private void button1_Click(object sender, EventArgs e)
{
string a = textBox1.Text;
string b = textBox2.Text;
Info.Add(a,b);
label4.Text = a + " " + b;
}
private void button3_Click(object sender, EventArgs e)
{
foreach (DictionaryEntry DE in Info)
{
label4.Text = ""+ DE.Key +DE.Value; //this only shows the first added value. How do I show the remaining values?
}
}
This is because each iteration of the loop replaces the previous value in the text. You can fix this by clearing out the text before going into the loop, and using += instead of =:
label4.Text += " "+ DE.Key +DE.Value
A better approach would be to use string.Join for this:
private void button3_Click(object sender, EventArgs e) {
label4.Text = string.Join(
", "
, Info.Select(p => string.Format("{0}-{1}", p.Key, p.Value))
);
}
I recommend you don't keep changing label4.Text in the loop, but build a string in the loop and change it once at the end. Something like:
StringBuilder allEntries = new StringBuilder();
foreach (DictionaryEntry DE in Info)
{
allEntries.Append(DE.Key);
allEntries.Append(DE.Value);
}
label4.Text = allEntries.ToString();
[I edited an earlier version of the code that didn't compile.]

The program is supposed to call start timer1 when a button is clicked, timer1 is 17secs long. Then in timer1 it is supposed to start timer2, which is 8secs long. For some reason it does not perform the timer2_tick function.
private void timer1_Tick(object sender, EventArgs e)
{
string[] ProxList = File.ReadAllLines("C:\\Prox.txt");
string[] s = new string[4];
WinInetInterop.SetConnectionProxy(ProxList[p]);
if (p > 3273)
p = 0;
s[0] = textBox1.Text;
s[1] = textBox2.Text;
s[2] = textBox3.Text;
s[3] = textBox4.Text;
try
{
webBrowser1.Navigate(s[txtBxNum]);
timer2.Start();
label1.Text = "Current Link: " + s[txtBxNum].ToString();
label2.Text = "Current IP: " + ProxList[p].ToString();
txtBxNum++;
if (txtBxNum > 3)
txtBxNum = 0;
}
catch { }
p++;
}
private void timer2_Tick(object sender, EventArgs e)
{
webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
}
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
try
{
webBrowser1.Document.GetElementById("skip_ad_button").InvokeMember("click");
}
catch { }
}
