Realtime charts with Microsoft Windows control charts

dinhanhency — Thu, 12 Aug 2010 08:06:27 GMT

Hi Guys.

I am building a project that draw a chart with real time using Microsoft Charts Control . Data source of chart changes every a few seconds to reload data. but i have got a trouble with it. The error is '{"Cross-thread operation not valid: Control...'

I use thread job to start thread every time when checking thread is complete.

private void gLoads()
{

jHOSEIDX = new ThreadStart(LoadChart);
tHOSEIDX = new Thread(jHOSEIDX);
GTimer.Interval = 10000; // 10 seconds
GTimer.Tick += new EventHandler(Otherwise);
GTimer.Enabled = true;
}

Here is otherwise method.

private void Otherwise(object sender, EventArgs e)
{
if (!(tHOSEIDX.ThreadState.ToString().CompareTo("Runn ing") == 0))
{
jHOSEIDX = new ThreadStart(LoadChart);
tHOSEIDX = new Thread(jHOSEIDX);
tHOSEIDX.Start();

}
}

Loadchart is a method reload data and adjust properties of chart.

private void LoadChart()
{

VnIndexChart.Titles[0].Text = "VN-Index";

string fileNameString = AppDomain.CurrentDomain.BaseDirectory + @"\Data\Data.mdb";

string myConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileNameString;

string mySelectQuery = "SELECT TGian,Data.Ngay, Data.ChiSoHTai, Data.ChiSoGLap,Data.KLDuMua FROM Data Order By 1; ";
OleDbConnection myConnection = new OleDbConnection(myConnectionString);
OleDbCommand myCommand = new OleDbCommand(mySelectQuery, myConnection);
myConnection.Open();
VnIndexChart.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConne ction);
VnIndexChart.Series["VN-Index"].XValueMember = "TGian";
VnIndexChart.Series["VN-Index"].YValueMembers = "ChiSoHTai";
VnIndexChart.Series["VN-Index"].XValueType = ChartValueType.Time;

VnIndexChart.Series["VN-IDX.ESTIMATE"].XValueMember = "TGian";
VnIndexChart.Series["VN-IDX.ESTIMATE"].XValueType = ChartValueType.Time;
VnIndexChart.Series["VN-IDX.ESTIMATE"].YValueMembers = "ChiSoGLap";

VnIndexChart.Series["Qlity"].XValueMember = "TGian";
VnIndexChart.Series["Qlity"].YAxisType = AxisType.Secondary;
VnIndexChart.Series["Qlity"].XValueType = ChartValueType.Time;
VnIndexChart.Series["Qlity"].YValueMembers = "KLDuMua";
VnIndexChart.DataBind();
UpdateChartSettings();

}

Help me fix the error.

Here's the link to the screenshot of my extracted bin folder

Databinding an Item in a collection to a controls in Silverlight xaml

aneke — Thu, 12 Aug 2010 04:25:58 GMT

Hi,

I am new to silverlight and I need help in implimenting a simple binding functionality in silverlight.

This is the senerio; I am trying to implement a cross language application that replaces the text property of a controls (ie Textblock etc ) on run time. This information is coming from the database and depends on the language the user selects on login. The challenge now is that I get all the words needed by a form with a function "getformlangRes(int32 formid)" which returns a dictionary(int32, string). Now I want to bind this list to the Textblocks on my form, specifying the key which decide the dictionary entry to display as the content of the textblock.

I have googled and binged but all I get is how to bind a collection to a listbox or combobox. Nothing about binding a Textblock to a particular dictionaryentry in dictionary.

Thanks guys in advance.

(Silverlight 4) Exceptions from a WCF service thrown by UserNamePasswordValidator

tkent_dna@hotmail.com — Wed, 11 Aug 2010 19:43:11 GMT

An oldish article (August 2009) by John Papa entitled, "Data Performance and Fault Strategies in Silverlight 3" (http://msdn.microsoft.com/en-us/maga...aspx#id0070028) outlines an effective strategy for returning faults (exceptions) from a WCF service to a Silverlight client, allowing the SL client to receive a meaningful exception rather than the dreaded 'NotFound' communication exception. The approach outlined by Papa, using an endpoint behavior that ensures the reply has an http status code of 200 (OK), works very well when it comes to handling exceptions once the call gets to a WCF service method. Exceptions are returned to the browser and forwarded to the SL client for its consumption.

However, if a WCF service has an HTTPS endpoint that uses a custom binding with the service must supply a UserNamePasswordValidator with a Validate() method. The Validate() method of the validator always gets called before the WCF method -- and that's appropriate, since credentials validation should occur before the WCF method is called. Here's the rub... When an exception is thrown from the Validate() method of the validator, the technique outlined in Papa's article doesn't work; that is, the custom endpoint behavior is not invoked and does not have a chance to alter the reply's status code. In this case, the dreaded 'NotFound' communication exception is received by the SL client.

Does anyone know of a technique to ensure that an exception thrown from a WCF service's UserNamePasswordValidator.Validate() method can get properly returned to a Silverlight 4 client?

TIA!
