Huge amounts of ListView-Items in ListView. Performance?

Hi there,

I am currently developing a CAN-Monitor (Controller Area Network). The messages
are received event-driven. At the moment the display of the messages is done by a ListView.
In the near future the number of received messages will grow up to ~ 600-800 messages per second.
The messages (encapsulated in a specific object) are delivered to the view via event to a event-handler-method.

Is there a alternative to the ListView which is more performant than the standard-one?

Thanx in advance!

The ListBox, but whatever control you use, as a user I can't read 600/800 messages per second. What's in the message that it needs to be displayed? If there's no specific information, I'd show a label saying (done msg x of y), and only show those who are "interesting" enough.

Even if there was such a control, how would a person make sense of a list that was constantly adding messages at an average rate of 700/sec? That sounds like the definition of information overload to me; I'd be more concerned with reducing the amount of information inserted into the list rather than finding a better list control.

If you absolutely must have a ListView with all of these messages, consider looking into the ListView's virtual mode. It might suit your task a little better.

That solution aside, could you look into using a different user experience that's a little more streamlined for your data?

What is it that you are not sure of?
How to add a property, or how to implement the functionality for the property once it is added?

DO NOT reply to this post, edit your original to make this clear!

you should write code like this code in user control
this code use for datagridview "RowHeaderVisible" property

public bool RowHeaderVisibl
{
get
{
return rowHeaderVisiblee;
}//get
set
{
rowHeaderVisiblee = value;
dataGridView1.RowHeadersVisible = rowHeaderVisiblee;
}//set
}//RowHeaderVisibl

Theoretically, yes, if they publish an API. Do I know of a library that does this? No, but Google works as well for you as it does for me.

I had a BHO.
When a web page is opened on IE, I try to replace the HTMLElement's text using

 foreach (IHTMLElement HtmlElemen in (IHTMLElementCollection)document.body.all)
{
try
{
HtmlElemen.GetType().GetProperty("innerText").SetValue(HtmlElemen, "NewText", null);
}
catch(Exception e)
{
 System.Windows.Forms.MessageBox.Show("Message:" + e.Message );
}
}

In some PC's the html element's text is replaced successfully with "Newtext",
but in some PC's it is not replacing.

And an exception message is obtained "Object reference not set to an instance of an object. "

How to fix this exception?

This is built in vs2005 c#.

The exception is obtained only in the PC's which doesn't have VisualStudio2005 or Vs2008.

Are there any dependencies missing for execution of these code.
In my installation Setup, I already added "Microsoft.Mshtml.dll" also.

Still this exception is coming. How can I avoid this exception and make it execute succesfully in all PC's?

SQL Reporting Services - programmatic report execution + export to PDF via WS/asmx

devvvy24-Jul-09 22:24

24-Jul-09 22:24

hello

Reporting Services in Microsoft SQL Server 2005 web service provides three endpoints:
http://IRISSQLPROD1/ReportServer/ReportService.asmx is provided for backward compatibility with SSRS 2000.
http://IRISSQLPROD1/ReportServer/ReportService2005.asmx is the new management endpoint in SSRS 2005.
http://IRISSQLPROD1/ReportServer/ReportExecution2005.asmx is the new execution endpoint.

I did a bit of research, I think among the above three ws endpoints, this is the one which will allow me to execute a report programmatically:

http://localhost/ReportServer/ReportExecution2005.asmx

However, I'm still looking for a sample - programmatic report execution via WS endpoint above and exported to PDF (saved on shared folder/local disk)

Thanks

By your description I guess the problem is your default printer is a PDF generator, or its output is set to "FILE".
Just set your default printer correctly and the bad dialog should go away. Smile | :)
