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

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.

No - but it's easy enough to write your own.

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.

Hi for all

I have nine buttons in my form and I would like how I can include a button's reference in an arraylist. I'll modify the text's value of a some button by this reference. How can I do this?

Thans for all

Alex

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 />

You might want to try

this.Cursor = myCursor;

datareader is a connected resultset, while the dataset is disconnected.
Have a look on MSDN for more detailed info though.

Cheers,
Simon
