Dear team,
Can you please help me out to integrate the Facebook Marketing API in my windows application using c#.
Please provide me the sample app code if possible, or please provide the URL to hit and the parameter need to pass on that URL.

I've been playing with jsPDF[^] lately. Aside from highly limited CSS support, it's fairly excellent.
The AutoTable plugin also works exceptionally well.

Is there a better way to run the Stop Watch:

}
Stopwatch StopWatch = new Stopwatch();
private void lblClock_Click(object sender, EventArgs e)
{
}
private void btnStart_Click(object sender, EventArgs e)
{
if (timer1.Enabled)
{
MessageBox.Show("Sorry you have already started the Timer");
}
else
timer1.Start();
this.StopWatch.Start();
}
private void btnStop_Click(object sender, EventArgs e)
{
if (timer1.Enabled)
{
timer1.Stop();
StopWatch.Stop();
}
else
MessageBox.Show("Timer Already Stopped");
}
private void btnPause_Click(object sender, EventArgs e)
{
StopWatch.Reset();
lblClock.Text = "00 HR :00 MIN :00 SEC ";
}
private void timer1_Tick(object sender, EventArgs e)

lblClock.Text = string.Format("{0:00} HR :{1:00} MIN: {2:00} SEC", Math.Floor(elapsed.TotalHours), elapsed.Minutes, elapsed.Seconds);
}
}

This very much depends on the application and level of accuracy required. Your sample provides the simplest solution, but it lacks a degree of accuracy, as everything is processed on the UI thread. Using this system, a timer event is actually placed on the message queue when it is signalled, and thus needs to wait its turn to be processed. This can cause a delay small in the processing of the tick, which over time, may accumulate.
To go to the next level of accuracy, you need to look at a System.Threading.Timer[^]. These fire events off in another thread, so there is no queue delays. It does, however, take a bit of effort to marshal the results back to the UI thread to update your controls.
The most accurate timer is the High Resolution Timer used in the Stopwatch Class[^]. This does not fire its own events at all, so you need to monitor its values in a separate thread, fire the periodic events in another thread, and then marshal all the results back to the UI for display.
All three options are good fun!
Cheers,
Mick

Don't use a StopWatch - just get the current DateTime.Now when you start the timer, and again when you stop (or lap check) it.
The Timespan difference will give you all the information you need.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Ehm, that looks like a hidden bug:
if (timer1.Enabled)
{
MessageBox.Show("Sorry you have already started the Timer");
}
else
timer1.Start();
this.StopWatch.Start();
Did you really mean that? Or rather
if (timer1.Enabled)
{
MessageBox.Show("Sorry you have already started the Timer");
}
else
{
timer1.Start();
this.StopWatch.Start();
}
Anyway, I recommend to always use {} with if and else - also with one-liners.

There is no problem with your code if that can solve your problem. From design point of view it looks great.
As one answer above mentioned that you can use many other types of solution to accomplish timing and scheduling task. That also depend upon your needs.
If you need a precise timer such as with 1ms accuracy (Stopwatch can very up-to 20-100 ms) then you should use multimedia timers.

Below is my Kendo code:
@(Html.Kendo().ComboBox()
.Name("cboTeamCode")
.HtmlAttributes(new { style = "width:90%;" })
.DataTextField("Team")
.DataValueField("Team")
.Placeholder("Select Team").Filter("contains").AutoBind(false).MinLength(1)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("GetTeamList", "Main"); //Set the Action and Controller names.
})
.ServerFiltering(true); //If true, the DataSource will not filter the data on the client.
})
.SelectedIndex(0)
)
Below is my Action method:
public JsonResult GetTeamList()
{
return Json(dba.GlobalDefaults, JsonRequestBehavior.AllowGet);
}
When I am running my code I am getting below error:
Error: Object doesn't support property or method 'requestData'
Below is the debugger code:
jQuery(function(){jQuery("#cboTeamCode").kendoComboBox({"dataSource";:{"transport":{"read":{"url":"/Main/GetTeamList","data":function() { return kendo.ui.ComboBox.requestData(jQuery("#cboTeamCode")); }},"prefix":""},"serverFiltering":true,"filter":[],"schema":{"errors":"Errors"}},"dataTextField":"Team","filter":"contains","minLength":1,"autoBind":false,"dataValueField":"Team","index" ,"placeholder":"Select Team"});});

You might have better luck getting an answer if you ask over in the Web Development forum, where the Web Developers hang out.

hi all
I have a search button and datagrid in c#, I require perform a query in the database and load the data in me datagrid
it is my code
conexion.ConnectionString = @"Data Source = SHINIL-PC040\SQLEXPRESS; Initial Catalog = produccion; Integrated Security = True";
if(TXTORDEN_PRODUCCION.Text == "" || TXTTURNO.Text == "" || TXTMAQUINAS.Text == "" || TXTHORAINICIO.Text == "" || TXTHORAFIN.Text == "")
{
MessageBox.Show("Te falta campo");
}
else
{
if (checkBox1.Checked == true)
{
try
{
comando.Connection = conexion;
conexion.Open();
string SqlAction = "select orden, turno, operador, horainicio, horafin, articulo, totalpiezasok, totalcajas, piezascondefecto, maquina from conteo2 where CONVERT(varchar(10), horafin, 108) >= @horainicio and CONVERT(varchar(10), horafin, 108)<= @horafin and orden = @orden and turno = @turno and maquina = @maquina ";
SqlCommand cmd = new SqlCommand(SqlAction, conexion);
cmd.Parameters.AddWithValue("@orden", TXTORDEN_PRODUCCION.Text);
cmd.Parameters.AddWithValue("@turno", TXTTURNO.Text);
cmd.Parameters.AddWithValue("@maquina", TXTMAQUINAS.Text);
cmd.Parameters.AddWithValue("@horainicio", TXTHORAINICIO.Text);
cmd.Parameters.AddWithValue("@horafin", TXTHORAFIN.Text);
}
conexion.Close();
}
catch (Exception Ex)
{
MessageBox.Show(Ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Hand);
}
}
MessageBox.Show("selecciono ok produccion");
}
if (checkBox2.Checked == true)
{
MessageBox.Show("selecciono paros");
}
if (checkBox1.Checked == false & checkBox2.Checked == false)

You never asked a question.
|
|
|
|
|
the Question is, as can I load the data back my search datagrid
|
|
|
|
|
Sorry, but can you ask your question in more detail? What exactly are you trying to achieve?
|
|
|
|
|
Yes you can. Loading the DataGrid is not a one time only operation.

Unfortunately, it is highly unlikely that someone is going to download your code and write the missing portions for you. We have no idea who you are so we are wary of downloading code; I have no doubt you are a fine chap but because I don't really know you, I can't tell whether or not your download will have been infected with something I don't want to install (albeit accidentally on your part).

As far as I remember this part you should first select the resistance-row (E6 , E12 , E24 , ...).
According to this selection you get (or calculate) the base-values for the row - for example E12 means 1.0 , 1.2 , 1.5 , 1.8 , 2.2 , and so on.
Now you should calculate the row-multiplier. For example your Input was 1344 Ohm. Now your multiplier for the base-values is 1000.
You take this multiplier, iterate through the row-values and multiply those value with the multiplier and compare if one value is smaler (or equal) than your entered resistor-value.
Now you check, which difference is smaler : to the last value of the row or to the next value of the row. The one with the smalest difference should be your reference-resistor.
With this resistor-value you build your color-table - but remember not each resistance-row has the same count of color-rings.
I think, you should start with this ...
