how to call timer in UC Control in Form Main?

Timer1 not start when add new User Control.I have 1 User Control (UC_Machine).And when load Form Main I using timer execute SQL query in query variable to get data from table [tbl_FF_Trigger]
I have 1 User Control (UC_Machine).And when load Form Main I using timer execute SQL query in query variable to get data from table [tbl_FF_Trigger]
-Code in UC_Machine:
private void UC_Machine_Load(object sender, EventArgs e)
{
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
string query = "SELECT CRDName, PartNumber ,DefectName FROM [tbl_FF_Trigger] where Machine = '" + Machine + "'";
db.fillDataGridView(query, dataGridView1);
dataGridView1.BackgroundColor = Color.White;
dataGridView1.RowHeadersVisible = false;
dataGridView1.Update();
dataGridView1.Refresh();
}
Code in form MAIN. Will get the information of the machines from the function Machine_Infor.GetMachine_Infors(). It will then create a UC_Machine array from that information. If the machine in the array does not already exist in the panellayout, it will be added to the panellayout.
In addition, it also checks if the machine exists in the tbl_FF_Trigger table. Otherwise it will delete the machine from the panellayout.
private void Main_Load(object sender, EventArgs e)
{
Get_Infor();
}
private void Get_Infor()
{
System.Timers.Timer timer = new System.Timers.Timer();
timer.Interval = 3000; // Thời gian chạy (5000 milliseconds = 5 second)
timer.Elapsed += Timer_Elapsed;
timer.Start();
}
private void Timer_Elapsed(object sender, ElapsedEventArgs e)
{
// Add new item to panellayout if machine have falsecall
var data = Machine_Infor.GetMachine_Infors();
var list = new UC_Machine[data.Count];
int i = 0;
itemFoods = new List<UC_Machine>();
itemFoodsFilter = new List<UC_Machine>();
HashSet<string> existingMachine = new HashSet<string>();
foreach (var item in data)
{
if (!existingMachine.Contains(item.Machine))
{
bool isExisting = false;
foreach (UC_Machine uc in myFlowLayoutPanel1.Controls)
{
if (uc.Machine == item.Machine)
{
isExisting = true;
break;
}
}
if (!isExisting)
{
list[i] = new UC_Machine();
list[i].CRDName = item.CRDName;
list[i].Model = item.Model;
list[i].Machine = item.Machine;
list[i].PartNumber = item.PartNumber;
list[i].Workcell = item.Workcell;
list[i].CRDName = item.CRDName;
list[i].Date = item.Date;
itemFoods.Add(list[i]);
itemFoodsFilter.Add(list[i]);
existingMachine.Add(item.Machine);
i++;
}
}
}
if (myFlowLayoutPanel1.InvokeRequired)
{
myFlowLayoutPanel1.Invoke((MethodInvoker)delegate
{
myFlowLayoutPanel1.Controls.AddRange(list.Where(x => x != null).ToArray());
});
}
else
{
myFlowLayoutPanel1.Controls.AddRange(list.Where(x => x != null).ToArray());
}
// Remove machine if Falsecall not found
string maincon = ConfigurationManager.ConnectionStrings["Connstring"].ConnectionString;
// Connect to the SQL Server database and execute the query to check for the existence of "vnhcmsleaoi05" in the "tbl_FF_Trigger" table.
using (SqlConnection connection = new SqlConnection(maincon))
{
connection.Open();
foreach (UC_Machine uc in myFlowLayoutPanel1.Controls)
{
string query = "SELECT COUNT(*) FROM tbl_FF_Trigger WHERE Machine = '"+ uc.Machine+"'";
using (SqlCommand command = new SqlCommand(query, connection))
{
int count = (int)command.ExecuteScalar();
if (count == 0)
{
if (myFlowLayoutPanel1.InvokeRequired)
{
myFlowLayoutPanel1.Invoke((MethodInvoker)delegate
{
myFlowLayoutPanel1.Controls.Remove(uc);
itemFoods.Remove(uc);
uc.Dispose();
});
}
else
{
myFlowLayoutPanel1.Controls.Remove(uc);
itemFoods.Remove(uc);
uc.Dispose();
}
break;
}
}
}
}
}
Code working OK when load Form. when tbl_FF_Trigger add new value myFlowLayoutPanel1 new UC_Machine
but timer1 not start. I know this because the datagirdview has no data in the newly added UC_Machine.I want when myFlowLayoutPanel1 adds 1 UC_Machine, timer1 will start
Anyone have any advise or solution for this case, please help me. Thanks a lot!

Your question is how to call timer in UC Control in Form Main. The main form is trying to GetInfo from the UC but consider that this might be "backwards" and that the UC Control should be notifying Form Main when it gets the new info instead. Here's what I mean:
Your UC has its own timer1 (we'll get timer1 started don't worry). What main form needs is to be notified when a new query is available in one of the UCs. Giving main form its own timer will interfere with an otherwise-orderly process. Consider making an event in your UC as shown and fire it whenever UC is done getting a new query.
UserControlMachine
Example: UC starts its own timer1 and fires RecordsChanged event when new query completes.
public partial class UserControlMachine : UserControl
{
public UserControlMachine()=>InitializeComponent();
public BindingList<Record> Records { get; } = new BindingList<Record>();
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
timer1 = new Timer { Interval = 2500 };
timer1.Tick += onTimer1Tick;
timer1.Start();
dataGridView1.DataSource = Records;
Records.Add(new Record()); // <- Auto-generate columns
dataGridView1.Columns[nameof(Record.DefectName)].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
}
private System.Windows.Forms.Timer timer1;
private void onTimer1Tick(object sender, EventArgs e) => queryDB();
private void queryDB()
{
// S I M U L A T E D Q U E R Y R E S U L T
Records.Clear();
for (int i = 0; i < Rando4Test.Next(1,5); i++)
{
Records.Add(new Record
{
CRDName = $"CRD-{(char)Rando4Test.Next(65,70)}{Rando4Test.Next(100, 200)}"
});
}
// Notify the Main Form that something has changed.
RecordsChanged?.Invoke(this, EventArgs.Empty);
}
public event EventHandler RecordsChanged;
// For testing purposes
public static Random Rando4Test { get; } = new Random();
}
Main Form
All the main form has to do is listen for RecordsChanged events.
public partial class Form1 : Form
{
public Form1() => InitializeComponent();
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
// Simulation: Add 2 machines
for (int i = 0; i < 2; i++)
{
var machine = new UserControlMachine
{
Size = new Size(myFlowLayoutPanel1.Width - SystemInformation.VerticalScrollBarWidth, 200),
BorderStyle = BorderStyle.FixedSingle,
};
myFlowLayoutPanel1.Controls.Add(machine);
// Listen for new query results
machine.RecordsChanged += onAnyUCRecordsChanged;
}
}
private void onAnyUCRecordsChanged(object sender, EventArgs e)
{
int totalDefects = 0;
foreach (var machine in myFlowLayoutPanel1.Controls.OfType<UserControlMachine>())
{
totalDefects += machine.Records.Count;
}
Text = $"Main Form - Total Defects: {totalDefects}";
}
}
WHERE Record class represents a DataGridViewRow
public class Record
{
public string PartNumber { get; set; } =
Guid.NewGuid().ToString().Substring(0, 13).ToUpper();
public string CRDName { get; set; }
public string DefectName { get; set; } = "Unknown Error";
}

C#_Timer/Stopwatch unable to continue from time extracted from database

I have below code to start and stop timer/stopwatch and load value into database.
The stopwatch works fine, and time is able to load into database and extract from database into textbox.
the problem is after i extract the time from database and insert into text box, then i start timer, it didnt start from current time. It always start from 0.
there is no error when running the program.
Could anyone help for troubleshoot please? Thanks in advance!

Microsoft Translate API is not working properly

I am trying to convert English text to Hindi text. For that I am using Microsoft Text translator API. But some of my text is not translating.
After googling I have found below code.
public string GetHindiText(string textToTranslate)
{
Carrier.ErrorCode = 0;
string TranslatedText = string.Empty;
try
{
Translator.LanguageServiceClient objTranslate = new Translator.LanguageServiceClient();
TranslatedText = objTranslate.Translate("***************", textToTranslate, "en", "hi");
}
catch (WebException ex)
{
Carrier.ErrorCode = 1;
return ex.Message;
}
return TranslatedText;
}
And I have added below service reference
http://api.microsofttranslator.com/V1/SOAP.svc
Most of the text is not translating. I need your suggestions to move forward.
Am I doing in correct way or anything I need to change. Any help is greatly helpful to me.
Thanks in advance.

Refer to the NuGet package NequeoNetTranslator, this contains text and speech translation APIs.
Sample of text translation this uses the new Cognitive version, first get your access token, through your translation [KEY]:
Nequeo.Net.Translator.Microsoft.Cognitive.Api apiat = new Nequeo.Net.Translator.Microsoft.Cognitive.Api(new Uri("https://api.cognitive.microsoft.com/sts/v1.0/"));
apiat.Credentials = new System.Net.NetworkCredential("[KEY]", "[KEY]");
string token = apiat.GetAccessToken();
Now call the translate method , this will translate en tode:
Nequeo.Net.Translator.Microsoft.Cognitive.Api api = new Nequeo.Net.Translator.Microsoft.Cognitive.Api(new Uri("https://api.microsofttranslator.com/v2/http.svc/"));
api.Credentials = new System.Net.NetworkCredential("[KEY]", "[KEY]");
byte[] data = api.Translate("hello", "de", "en", null, token);
Translation[] tran = api.Translate(data);
string tranText = System.Text.Encoding.Default.GetString(data);
If you are using speech to text then sample code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
Nequeo.Net.Translator.Microsoft.Cognitive.SpeechApi apiat = null;
private void button1_Click(object sender, EventArgs e)
{
apiat = new Nequeo.Net.Translator.Microsoft.Cognitive.SpeechApi(new Uri("wss://dev.microsofttranslator.com/speech/"));
apiat.Credentials = new System.Net.NetworkCredential("[KEY]", "[KEY]");
string token = apiat.GetAccessToken(new Uri("https://api.cognitive.microsoft.com/sts/v1.0/"));
apiat.OnRecording += Apiat_OnRecording;
apiat.OnStopRecording += Apiat_OnStopRecording;
apiat.OnTranslationReceived += Apiat_OnTranslationReceived;
Nequeo.IO.Audio.Device device_in = Nequeo.IO.Audio.Devices.GetDeviceIn(0);
apiat.AudioDevice = device_in;
apiat.WriteStream = new System.IO.MemoryStream();
apiat.Translate("hr-HR", "en-US", token);
}
private void Apiat_OnTranslationReceived(object sender, EventArgs e)
{
System.IO.MemoryStream jj = (System.IO.MemoryStream)apiat.WriteStream;
string gg = Encoding.Default.GetString(jj.ToArray());
Nequeo.Net.Translator.Microsoft.Cognitive.SpeechTranslation dffddf = apiat.GetSpeechTranslation();
}
private void Apiat_OnStopRecording(object sender, EventArgs e)
{
bool kk = true;
}
private void Apiat_OnRecording(object sender, EventArgs e)
{
bool kk = true;
}
private void button2_Click(object sender, EventArgs e)
{
apiat.StopTranslate();
}
}

How can i get my datagridview code let work in a datagrid

articles from the database.
But i need a wpf not a win forms project. The problem is in wpf you don't have a datagridview.
Now i have try for let work it with a datagrid but there are no row options.
i have already found how i can load the data from the wcf in my datagrid with this DgArtikel.ItemsSource = ds.Tables[0].DefaultView;
but how can i let work the insert update and delete button ?

objects in datagridview

Im adding objects to a datagridview ( only one kind) through a list
ej.
List<Material> mater = new List<Material>();
DataGridView dgvMAterial = new DataGridView();
dgvMaterial.DataSource = null;
mater.Add((Material)cmbMaterial.SelectedValue);
dgvMaterial.DataSource = mater;
But every time I click over the datagrid I get an indexoutofrangeexeption.
Can somone tell me why?

That's probably not DGV problem, but with this combo box. Show us the code that fills combo box and sets its properties.
If you are casting to Material class you should probably use SelectedItem instead of SelectedValue. (unless you exactly know what you're doing)

I would guess that you have an event-handler that isn't happy. What exactly does the message say?
You might also be having problems if you are adding the same Material instance to the list multiple times; since IndexOf will only find the first occurrence. This line makes me very suspicious:
mater.Add((Material)cmbMaterial.SelectedValue);
since it could potentially (on consecutive clicks / etc) do exactly this.
Note: if you used BindingList<T> instead all you'd have to doo is Add(...) - no resetting required:
field:
BindingList<Material> mater = new BindingList<Material>();
init grid:
dgvMaterial.DataSource = mater;
add item:
mater.Add(newInstance);

If you assign data source to the DGV you should check element count - if zero then assign null. I don't know why this is the way it is, but I'm doing it in all my forms.
