if (obj is double) wins!
Gives me 2x speed over obj.GetType() == typeof(double).
Thanks!

As far as performance goes, there are only two rules:
1) shorter code is always faster
2) rule 1 is false

I didn't think that 'is' would work for a value type ? Or is that just 'as' that won't work ( as it can't return null ) ???

Sure is is always OK (it produces a bool) whereas as is not.

Hi, I want to replace any 2 words if found in a line. The 2 words can be on the same line or one on each line.
string line ="hello World, expression";
Regex regx = new Regex("hello"); //how can i optionally put to search either, "hello" and "expression" in a line
if (regx.IsMatch(line))
{
sb.AppendLine(regx.Replace(line, "replaced"));//if "hello" put "H" or if "expression" put "E"
}
Thanks

You can use the replace method on the string class, you don't need regex for this. There is a RegEx.Replace if you prefer.

Hi again!
Last Problem get solved very fast - thx to Luc! This time, i had another problem with printing...
How do i get the last page (number of page) that will be printed at PrintPage - Event?
i want something like that:
Page 1 from 9 (where 9 is last page that will be printed)
i want to print Page x from x on any page... at footer line - anyone does know an solution for?
i did something like that
private int LinesThatFit(PrintPageEventArgs e, PointF curPosition)
{
int CalcSum = (e.MarginBounds.Bottom - (int)curPosition.Y);
int CalcRows = CalcSum / newFont.Height;
return CalcRows;
}
this works - but only for a static height - or better a static font height - i draw a string by DrawString - but if it's wrapped, the LinesThatFit doesn't work correct...
Thx again for any solution - i searched for this problem around 2 days... and found nothing - the LinesThatFit is an own creation... but that was when i just had line for line with none wrapped text!
Hope someone get's it!
Bye!

put a counter if you are calling your print function last time then use if condition and then
e.Drawstring(.....);

If you use SingleLine mode, the regex works. Just tested in Expresso

Is it pssoble to use a VS.net wizard at runtim?
For example I want to use "TableAdapter Configuration Wizard" at runtime to generate Dataset.

No, it's part of VS.NET, not part of the runtime.

Hello,
I have a listview on my form, but I do not want it to respond to keyboard input as I want to use the keys for something else.
Currently, when the listview is populated with items and I press a key (say, the 'm' key) the listview will change selections to the first item that starts with an M. I would like it not to do that please. 
I am guessing this is where I can use 'protected override' (or something like that) however I am new to C# and I haven't grasped that yet.
All help is most appreciated. Thank you

I like to find out programatically the users for the printers in C#
That is if you go to start -- settings -- printers and faxes and select a printer and right click
its properties you should find security there.
I want to access the users inside that security and see if a particular user is there programatically.
I did some research and found out that Win32_Printer class can be used to get all the printers connected to
a computer but not able to figure out how to get to the security of it.
Any help is greatly appreciated.

Hi, I have an windows Form which I don't want user to resize. In VS2003, I remove the minimized, maximize button, set the Locked property to true and everything is OK. Now, I upgraded to VS2005, this don't work anymore. The window can be resized. Is this a bug of VS2005? How can I do it? I tried to set max size and min size to the same and now the form has fixed size. But when I move the cursor to the edge of the form, cusor changed to hint that I am allowed to resize window. It's annoying. So, I don't think this is a good way to do it. Do you guys have any good idea?
Thanks.

You need to set the frame to be fixed, this is a property on the form, which I don't think has changed.

Hello,

This should give you a collection of installed printers. (doesn't mean that they are connected!)
System.Drawing.Printing.PrinterSettings.StringCollection installedprinter = System.Drawing.Printing.PrinterSettings.InstalledPrinters;

Sorry, don't understand your question.
All the best,

1.For the first i think i figured out. Using System.Management API you can actually get the printers online.
2.If you go into the windows and go to start-settings-printers and faxes, select a printer and right click properties. You
will find security and inside it you will find users. Is there a way to get to see those users programatically through c#
