Windows Form Freeze

Shyamraja1-Sep-09 1:11

Hi All,
I have created a custom video player in C#. This player has two forms.
1. The Video Player window ( running in primary (UI) thread )
2. The content playing window (running in a secondary thread)

Everything goes fine for nearly 5-6 hours, then the main video player window freeze.So i cannot access any of the buttons (stop, pause ,exit) in the player.

But the secondary thread keeps playing the files for even two days continuously ( which is the max i tested).

Things i have checked :
1. There is no memory issue, since i dispose the objects i create after playing each file ( few min videos) . I have checked the process in task manager, where status is running and memory usage as same as it is started.

2.I have used BeginInvoke from secondary thread to update the current playing file in the list box on the main video player window ( once the main window freeze, the update is not visible)

3. I have used a timer in the main video player window and tried refreshing form , calling Application
.DoEvent() for every few minutes , still it gets freeze up after 5-6 hours.

Why the UI window freeze up?
Is my architecture for the player is wrong?
(I need to do lots of processing in secondary thread for the images and videos to be played, but it is working fine)

Kindly give me your suggestions.

You can't display doc file into rich text box.It supports only rtf files or text files.

Of course ,you could open any file and read it's data but you still can't display doc into RichTextBox.Ask google and you will find this question many times and it's answer is the same -you can't.

[EDIT]
doc file is not simple text file and you couldn't view it's contents with Notepad. It's based on binary format specification and RichTextBox doesn't recognize it.
You could view or edit doc file with Word or with some third party libraries or with creating your own parser and viewer.

You can import word doc into richtextbox with following:

private void PreviewRecord(object sender, EventArgs e)
{
string str;

OpenFileDialog openfiledg = new OpenFileDialog();
openfiledg.Filter = "Word Document (*.doc)|*.doc|All Files (*.*)|*.*";
openfiledg.FilterIndex = 2;
openfiledg.RestoreDirectory = true;
if ((openfiledg.ShowDialog() == DialogResult.OK && openfiledg.FileName.Length > 0))
{
IDataObject Data1;
object nullobj, file;
Microsoft.Office.Interop.Word.Document wordDoc;
Microsoft.Office.Interop.Word.ApplicationClass WordApp = new Microsoft.Office.Interop.Word.ApplicationClass();
nullobj = System.Reflection.Missing.Value;
file = openfiledg.FileName;
wordDoc = WordApp.Documents.Open(ref file, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj, ref nullobj);

wordDoc.ActiveWindow.Selection.WholeStory();
wordDoc.ActiveWindow.Selection.Copy();
Data1 = Clipboard.GetDataObject();
str = Data1.GetData(DataFormats.Rtf).ToString();
richTextBox1.Rtf = str;
wordDoc.Close(ref nullobj, ref nullobj, ref nullobj);

}
}

Slow in displaying Crystal report

Hi, I am using CrystalReport XI-R2, in my application. I have used a Types Dataset and DataTables in the report. Data retrieved from querry has been added in the DataTable and in the report the DataSource of the report has been set that DataTable.
This report displays values correctly. There are nearly 5 custom querries and 3 Subreports in the report. The problem is that in the display of report it is displayed nearly after 1 minutes which is very slow in my requirement. Please suggest me, what is its solution.

Please Check the following:

1) Which DB you are using.

2) Are you retrieving the data in Network

3) Is that Windows application or Web application

Check where is the actual delay

Is that in binding ?
Is that in Fetching ?

then you can get some idea.

I have used Oracle10g Database. Yes is retrieved by client side from server. This is windows application.

In my report In crystal report oracle Database is not connected. used Dataset and DataTable. my coding pattern is like this.

private void btnTestReceipt_Click(object sender, EventArgs e)
{
ReportDocument rptdmt=new ReportDocument();
DataTable dtr=GetDatas();
string ReportName = Application.StartupPath + "\\Reports\\rptCashReceiptPP.rpt";

rptdmt.Load(ReportName);
rptdmt.SetDataSource(dtr);
CrystalReportViewer.ReportSource = rptdmt;
}

private DataTable GetDatas()
{
StringBuilder sb=new StringBuilder();
sb.Append("SELECT *from TableName WHERE CONDITION");
DataTable dt=_con.ExecuteDataTable(sb.ToString());

DsDataSet.UserDataTable dtrep=new DsDataSet.UserDataTable(); //This is object of DataTable of Typed Dataset named DsDataset.

foreach(DataRow dr in dt.Rows)
{
dtrep.Rows.Add(dr.ItemArray);
}
dtrep.AcceptChanges();
return dtrep;
}

Indexers Question

Hi all,

I am looking for a more advance way of using an indexers. I have searched the net but cannot find anything that explains how I must accomplish the following:

I have three classes namely: Building, Controller, Reader (each with their own fields/properties/methods). I want to make use of an indexer to reference each of the classes so that it can following this pattern:

Building["MyBuilding"].Location = ".....";
Building["MyBuilding"].Controller["MyController"].Area = ".....";
Building["MyBuilding"].Controller["MyController"].Reader["myReader"].Tag = "......";

Many thanks in advance
Kind regards,

Assuming you are not using static classes in your example:

Dictionary <string,Building> building = new Dictionary<string,Building>();
Building myBuilding = new Building();
//... Other stuff here....
building.Add("MyBuilding", myBuilding);
//Now You can:
building["MyBuilding"];

in the class definition of Building there should be a property like:

public Dictionary <string,Controller> Controller {get; private set;}

And follow the same method for Reader in the controller class.

Let me know if this isn't what you want.

Well, kinda ... I was actually hoping not to make use of generics collections.

But on the other hand, lets see what I can do with this....
