Hi
I don't know if it's possible to include any File to a project. But I dont't think so.
But if you want to read a text file you can use the StreamReader Class.

Example:

using System.IO;

string read ="";
StreamReader sr = new StreamReader("c:\\readme.txt");
sr.ReadLine();//or any method you need
read = sr.ReadLine().ToString();
sr.Close();

Hi,

You can change the column title using ColumnName property of DataColumn.

ds.Tables[0].Columns[0].ColumnName = "Employee Id";
ds.Tables[0].Columns[1].ColumnName = " Employee First Name";

Change the column names before associating the data set with the data grid.

Hope this will help you.

Hi
I think you need something like OpenFileDialog.
Try this:

OpenFileDialog openfile = new OpenFileDialog();
openfile.Show();

Enable/Disable Local Area Connection

My application re-configures the network settings (IP, Subnet Mask, Gateway, DNS..) and after that I want to disable and then enable the Local area connection (not the network card), so the connection is refreshed with the new settings without having to restart the computer. Does anybody have any idea on how to do it in C#? Thanks for your time.

You don't have to disable/enable to network card to get the settings to refresh. You can make the changes using WMI, but watch the return codes. No matter what method you chose to make those changes, Windows will tell you if the machine has to be restarted for the changes to take effect. Otherwise, in most cases, the changes you make take effect immediately.

C# - Double Quotes

econner5-Mar-05 15:22

I have a field in a database that contains a value with double quotes ("Test Value"). I am trying to use this in a javascript by writing it back out. I need to be able to seach the string for double quotes and replace them with \" so that the end result is \"Test Value\". Is there a function in .NET to handle this? In Delphi, there is a QuotedStr() function.

Returning graphics from user control

Hi people,

I have a user control that draws a Bezier (drawing occurs in OnPaint and OnPaintBackground). This control is used in a windows form. Is there a way to get the graphics of that control to be able to save it in a file?

thanks,
Talal

hi again,

well I managed to send back the Bitmap to the main form, but I had to recreate it in the returning function. I was wondering if there is a way to get back what I had already drawn in the control.

thanks,
Talal

<td class="subhead" colspan="2">(?<content>.*?)</td>

where group "content" will contain text "I NEED TO EXTRACT THIS"

or more generaly,

<td(.*?)>(?<content>.*?)</td>

RETester[^] is nice place for testing... Check out Reg Ex Lib, too.

Does simply adding the Button object not work? Something like

<br />
class MainForm<br />
{<br />
  private Button b1 = new Button("B1");<br />
  private Button b2 = new Button("B2");<br />
<br />
  ArrayList a = new ArrayList();<br />
<br />
<br />
  public void AddToList()<br />
  {<br />
     a.Add(b1);<br />
     a.add(b2);<br />
  }<br />
<br />
  private void ModifyText()<br />
  {<br />
     foreach(Button b in a)<br />
     {<br />
          b.Text = "Long live Senthil";<br />
     }<br />
  }<br />
}<br />
