You can also use RegEx to strip the html tags from the response.

<br />
public string cleanHtmlTags(string inputText)<br />
{<br />
	Regex objRejex = new Regex("<([^>]*?)>");<br />
	return objRejex.Replace(inputText, "");<br />
}<br />

populating the dynamically generated textboxes on click of a dynamically generated button.

I have a web page with dynamically geneated textboxes and buttons. On click of a button, I want to pull the values from the database and populate the textboxes. I am gettinng confused between the sequence in which the client and server side code gets called. If I call server side first and then client, practically it happens in opp order . For eg-

TableCell tblCell5 = new TableCell();
System.Web.UI.WebControls.Button btn = new System.Web.UI.WebControls.Button();
btn.Text = "Copy";
btn.ID = "btnFetch"+ count.ToString();
counter = count;
btn.CommandArgument = count.ToString();
btn.Command += new CommandEventHandler(RemoveFiles);

btn.Attributes.Add("onclick","setit(" + count + "," + crash +","+ cr +","+ cav+"); ");
tblCell5.Controls.Add(btn);
tblRow.Cells.Add(tblCell5);

Even if I call in this order and set the values of variables in RemoveFiles, the javascript functions gets called first and by that time, the variables are not set.

Also if I try to call javascript from server side function, he javascript function is not yet loaded. For eg-
protected void RemoveFiles(Object sender, CommandEventArgs e)
{
stag = 1;
Response.Write(" alert("+ e.CommandArgument.ToString() +")");

cr = 6;
cav = 9;
hrs=10;
crash = 6;
Response.Write(" setit(' + count + ',' + crash +','+ cr +','+ cav+'); ");
}

Any suggestions?

Datatable Adding Row

I'm returning a datatable from the DB, I need to add a row to that datatable for display only. That piece is working fine, the issue is I need that record to be the first record displayed in the cbo box.

System.Data.DataRow dr = WorkTable.NewRow();
WorkTable.Rows.Add(new object[] {"ALL", "AL","","","","","","",-2,1,"UNKNOWN"});

cbo.DataSource = WorkTable;

--I need to have the added line first in the combo box.

Thanks

Instead of setting the data source of the combobox to the table, set it to a sorted view. Then all you need to do is make sure that the view is sorted so that your new row is first ... perhaps by adding a new column to the table that is null for everything other than your new row. I tried this quickly, and seems to work OK, but it looks like the sort put's null values ahead of non-nulls, so you'll need to do a descending sort.

C# Network Problem

We have an app that will not run on a single computer from the network (works fine locally). I have adjusted .NET security setting the Local Intrenet to Full Trust, but the app still crashes when trying to launch.

Any other ideas?

How do you start the application, exactly?
If you're trying to run it from a UNC path, then the internet zone security settings will apply, even if the computer is in your local intranet.

mav

Re: C# Network Problem

We browse to the network path (e.g. Z:\C# Stuff\Program Folder\Program.exe) and run it directly.

This is the only computer that will not run it from the network (we have 50+ that run it just fine).

-- modified at 14:04 Tuesday 4th October, 2005

The .NET internet security settings are full trust also.

CPU Usage

Dear All,

I want to check the CPU Usage in C#. May be through Perfprmance counters?? Can I get sample code for that.

With Regards
Manoj

Re: CPU Usage

Heath Stewart4-Oct-05 10:53

What type of CPU usage you want to check is important. You can browse the various performance counters and read their descriptions using the Server Explorer tab in Visual Studio - right-clicking on the perf counter you want and select Properties - or use perfmon.exe o NT-based Windows OSes.

An example of just getting values every .5 seconds follows:

using System;
using System.Diagnostics;
using System.Threading;
 
class Usage
{
  static void Main()
  {
    using (PerformanceCounter pc = new PerformanceCounter())
    {
      // Use a specific counter for all CPUs.
      pc.CategoryName = "Processor";
      pc.CounterName = "% User Time";
      pc.InstanceName = "_Total";
 
      Console.Error.WriteLine("Total % User Time:");
      Console.Error.WriteLine("Press any key to exit...");
 
      ThreadPool.QueueUserWorkItem(new WaitCallback(Count), pc);
      Console.Read();
 
      Console.Error.WriteLine("Done");
    }
  }
 
  static void Count(object state)
  {
    PerformanceCounter pc = state as PerformanceCounter;
    while (pc != null)
    {
      Console.WriteLine("{0,3:f2}%", pc.NextValue());
      Thread.Sleep(500);
    }
  }
}

You can still use the performance counters and should consider taking a brief running average before giving more work to a CPU. CPU usage goes up and down and performance counters only have so much resolution between ticks (no where near as fast as a CPU tick).

There is actually APIS for clustering in Windows available either as automation objects (which you can use with a Runtime-Callable Wrapper (RCW) created by tlbimp.exe) or native functions you can P/Invoke. See http://msdn.microsoft.com/library/en-us/mscs/mscs/windows_clustering.asp[^] for details.

Displaying an owned form when main form is shown

Luis Alonso Ramos4-Oct-05 5:11

Luis Alonso Ramos

4-Oct-05 5:11

Hello,

I have an MDI application. At the start of Main I call EnableVisualStyles and DoEvents to enable XP theming and everything works fine.

But now, I'm trying to automatically simulate a click event for a menu item to display a login form on top of that MDI parent.

First I tried to display the form the first time the Activated event is fired for the MDI parent, and it kind of works, but the main form is displayed partially resized (titlebar is resized to saved position, but not client area) and only totally paints itself after the login form is closed.

I have a timer, so I tried setting a flag and displaying the form the first time the Tick event fires for the timer, before clearing the flag. This to wait for the form to process all the creation events. And it works perfect, except that I don't get visual styles in any of my application's dialogs (but I do in toolbars and message boxes.)

I'm using .NET 1.1 (VS 2003) on Windows XP.

So, any ideas?

Hi!

You could also try using the Application.Idle event instead of your timer. That way the menu item click is simulated when the application is finished initializing the main form.

Remoting URI question ?

Member 127995794-Oct-05 5:10

Member 12799579

4-Oct-05 5:10

I am new to remoting and have created 3 projects on the same machine

1) Server object
2) Server activation object
3) Client

The client calls the server activation object which includes specifying a URI to show where the Server activation application resides. This client code might look something like this...

TcpClientChannel ch = new TcpClientChannel();
ChannelServices.RegisterChannel(ch);

RemotingConfiguration.RegisterWellKnownClientType(
typeof(SAO_server_single_call.clsSAO_singlecall),
"tcp:davelaptop:1234/clsSAO_singlecall");

objSAO_singlecall = new SAO_server_single_call.clsSAO_singlecall();

Can anybody tell me how to work out how the URI should be constructed? I've not used them much before. My computer is called 'davelaptop' and the client activation server project lives at 'D:\Work\Exercise\RemotingTest\RemotingTest\TestServer'

Can anyone tell me what the URI should look like or tell me where I'm going wrong?

Thanks in advance - Dave

Re: Remoting URI question ?

S. Senthil Kumar4-Oct-05 6:07

The URI doesn't have anything to do with the physical location of the server. You only need to provide the port number of the channel which you registered on the server. For example, if your server code looked like this

ChannelServices.RegisterChannel(new TcpChannel(8082));
RemotingConfiguration.ApplicationName = "HelloServiceApplication";
RemotingConfiguration.RegisterWellKnownServiceType( typeof(HelloService),
                                                            "MyUri",
                                                         WellKnownObjectMode.SingleCall 
                                                          );

Then the client call will look like

RemotingConfiguration.RegisterWellKnownClientType(
typeof(SAO_server_single_call.clsSAO_singlecall),
"tcp://localhost:8082/HelloServiceApplication/MyUri");

im using visual studio beta 2
i have richtextbox and listbox in my C# windows application.
my application works like intellisense/Autocomplete like typing System, then a "."
inside Visual Studio .NET will show a drop down list of types for the System namespace.
when i type a recognized word into the richtextbox then a period/fullstop,
a listbox appears.

problem:
how do i position my listbox to appear right after the period('.') i would have typed in my richtextbox

code example would be appreciated

thanks Smile | :)

listBox.Location = richTextBox.GetPositionFromCharIndex(richTextBox.SelectionStart);

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
