c# datagrid - word wrap [modified]

Hi In my web application, I am using a datagrid to display some text which can be of any length. If the text is very lengthy, the datagrid expands and the appearance of the page is weird.
Is there any way to wrap the datagrid text. I found a way listed from online help which works only for IE browser. I want the application to be hosted in any browser. When I open the application in Firefox, the wordwrap doesn't work.
The suggested solution was to apply styles mentioned below to the datagrid.

.Grid<br />
{<br />
	table-layout: fixed;<br />
}<br />
<br />
.GridColumn<br />
{<br />
	white-space: pre-wrap; /* css-3 */<br />
	white-space: pre-line;<br />
	white-space: -moz-pre-wrap !important; /* Mozilla, since 1999 */<br />
	white-space: -pre-wrap; /* Opera 4-6 */<br />
	white-space: -o-pre-wrap; /* Opera 7 */<br />
	word-wrap: break-word; /* Internet Explorer 5.5+ */<br />
}<br />

Can anyone help in word wrapping the datagrid text in other browsers.

Thanks in Advance

hello Adeel,
Thanks for your reply.

Since I was occupied with other works, I looked into your response late.
Since in our application uses gridiview, I think the property you had mentioned is not available. Can anything done for word wrapping with gridview.

HTMLDocument problem

Hello,
I have a problem using MSHTML.HTMLDocument in my winforms/c# application. I use that stuff from Microsoft.ConsultingServices.HtmlEditor to present and edit HTML in my app. The problem is when I paste some text from Word, which includes comments, I get an error (originating from HTMLDocument, or WebBrowser, I'm not sure) that says I have error on my page (basically it's javascript error, but its irrelevant). I just need to somehow trap this error and prevent it from shoving to the user. Can I use any properties/methods/events of HTMLEditor, or HTMLDocument to prevent it from showing those errors?
Thanks

Error is:

A Runtime Error has occured
Do you wish to Debug?

Line: 203
Error: Object expected

The error is not a problem, I know it's cause (there are some javascript function calls in onmouseover events, but javascript itself is not present). I just want to ignore and not show it.

Empty matrix

Russell^'27-Apr-07 3:32

One simple questions abuot matrixes:

<br />
<br />
public class MyClass<br />
{<br />
   private int[] List;<br />
   ...<br />
   void SetDimension(int L){<br />
      List=new int [L];<br />
   }<br />
   int GetListLength(){<br />
      return List.Length;<br />
   }<br />
}<br />

The function GetListLength failed (Iusing .Length) if it is never called SetDimension before, but I like that that function returns 0.
So, How to know that List is declared but not defined?
That is, Is there any propertyes like List.IsUndefinied() that I can use?

Cheers,
Russell

In the constructor for MyClass set List to null. Then GetListLength can check it to make sure List is non-null before it tries to access its members.

MediaPlayer

hello everyone,

I am trying out a few things with MediaPlayer. I am currently creating the Windows Media Player Control Programmatically(i.e without adding a MediaPlayer control into the Application, I need to run it)

After downloading the MediaPlayer SDK and adding wmp.dll reference,
I am using the below code to do this.

WMPLib.WindowsMediaPlayer Player;

private void PlayFile(String url)
{
Player = new WMPLib.WindowsMediaPlayer();
Player.PlayStateChange +=
new WMPLib._WMPOCXEvents_PlayStateChangeEventHandler(Player_PlayStateChange);
Player.MediaError +=
new WMPLib._WMPOCXEvents_MediaErrorEventHandler(Player_MediaError);
Player.URL = url;
Player.controls.play();
}

private void Form1_Load(object sender, System.EventArgs e)
{
// TODO Insert a valid path in the line below.
PlayFile(@"c:\myaudio.wma");
}

private void Player_PlayStateChange(int NewState)
{
if ((WMPLib.WMPPlayState)NewState == WMPLib.WMPPlayState.wmppsStopped)
{
this.Close();
}
}

private void Player_MediaError(object pMediaObject)
{
MessageBox.Show("Cannot play media file.");
this.Close();
}

Problem:
I got the above code from MSDN and it is playing the video file at the background but I am not able to see the MediaPlayer on the monitor. I can just hear the audio of the file. Can someone tell me what the problem is.
There is nothing wrong with the windows media player as far as I know

Thanks and Regards
kraj

Hey. Thanks for the reply. But there is a problem with OpenPlayer. I have tried that method before. Player.OpenPlayer(url) opens the MediaPlayer and plays the video file but we lose control over that player(i.e U cannot Stop or Pause the MediaPlayer Programmatically). Player.Stop(), Player.Pause() doesn't work.

Unique value generation?

Hey,

In our application, I want to generate 8 characters hexadecimal unique value always.

I tried with GUID.gethascode.Tostring("x") but sometimes even it creates dupilcates.

It should generate unique always.

Thanks

Kusuma

Well, you can't hope to create unique values in 8 characters. It's just not going to happen - look how long a GUID is.

If you really want truly random numbers, there is a web site called www.random.org that will provide truly random numbers. On the site you can read about how the numbers are generated.

RTB nuances

27-Apr-07 1:09

Hello all,

I'm trying to add line numbers to a RTB by wrapping the RTB in a UserControl.
I move the RTB to the right to allow room for line numbers which I draw in the exposed UserControl area at the left margin. I have a property which allows me to get/set Fonts to be used for Text and Line numbers but when I do a pe.Graphics.MeasureString the numbers in the UserControl and the text don't match up for some reason?

//Code to draw line numbers in exposed UserCOntrol area
SizeF szLN = pe.Graphics.MeasureString(strLineNum, textFont);
int ln = firstVisibleLine + 1;

for (int i = 0;
(i <= lastVisibleLine) && (ln <= richTextBox1.Lines.Length);
i++)
{
pe.Graphics.DrawString(ln.ToString(), textFont, sb, pt);
pt.Y += szLN.Height;
++ln;
}

Any help on this and any other nuances with the RTB control would be of great help.

Thanks,
Mike
