Re: How To Get The Row Count Of Datagrid Including Automatically Generated Row

Hello,
You can get the CurrencyManager and access its Count property.

CurrencyManager cm = dataGrid.BindingContext[dataGrid.DataSource] as CurrencyManager;<br />
if(cm != null)<br />
  int count = cm.List.Count; //Total rows in the grid.

HTH. Cheers Smile | :)

Hex question

in MFC if I wanted a hex value in a string I could put in \x04. How do I add hex to a string in C#. Do I do it the same?

Thanks

Yes.

You can also use Unicode. "\u0082" == "\x82".

Bar Code Reading

I need to create a program that reads in bar codes. Would you be able to suggest how I might go about that task? Thanks

Most bar code readers stand in between the end-user and the keyboard. So that when you scan a barcode it's as if they typed in the numbers on a keyboard. So just place your cursor where it needs to go and scan a bar code. It should fill. I've tried this with the USB as well as the PS2 barcode readers. The PS2 connects to the keyboard PS2 port on the PC and then with a "Y" cable that the keyboard plugs into.

Good luck

Parsing a string

Tom Wright9-Jan-06 9:55

I've writtne a program that receives a string via TCP/IP. This string is made up of different data fixed fields. Sort of like thisissomedatablahblahblah. So if I know the field lenghts is there a way to copy data starting at a particular spot and reading for a particular length and returning that data?

Something like ReadTo(6, 4) which would return the word "some".

Thanks

Look at the Substring method of the string class.

string.Compare using wildcards

Hi,
I'm trying to search a datagrid/datatable using string.Compare, and doing something wrong when trying to use wildcards. I have searchThis as the string to search for, which works fine with string.Compare(search, searchThis);. But when I try to make searchThis = "*" + searchThis + "*"; it doesn't work. I'm sure it's pretty simple, but haven't been able to find the answer yet.
Thanks for any help!
Mel

The Compare method doesn't support wildcards.

If you want to search entire strings with wildcard support, you'll have to use Regular Expressions[^].

I am trying to display a number with two places to right of decimal. When the number diplays it truncates the trailling zero. I want to see .50 but I see .5

after I changed my datatype in the database to decimal from float. the number shows up like 2.25000009944

can someone tell me how do I display 1.50 with the zero in the database and the UI (web form). I tried looking for formatting in help but i can seem to get it right.

Thanks

Hi,

I think you should look around string.Foramt() methode which can have parameter like NumberFormatInfo MSDN

Or, like this example, you can use the ToString() methode :

string NumberPrettyPrint(int number){
	// Gets a NumberFormatInfo associated with the en-US culture.
	NumberFormatInfo nfi = new CultureInfo( "en-US", false ).NumberFormat;
	nfi.NumberDecimalDigits = 2;

	return number.ToString("N", nfi);
}

Hope that can help

Hi,

It's been a while since I've posted in here!
Last Time I was using Visual Studio 2003.NET and mainly using C# Version 1.1
and C++.NET 1.1.

I'll be getting Visual Studio 2005 this week hopefully.
I know it came out in November, but Im not from the US, good ole England, and we're just getting over here.

Amazon UK Visual Studio 2005 Release Date : January 27, 2006 -
Visual Studio 2005 @ Amazon UK

I'm now coding in C# 2.0, using Visual C# Express and Visual Basic.Net Express
and hopefully moving onto C++.NET 2.0 as well. The Managed Framework looks wicked! Cool | :cool:

Anyway all that has nothing to do with why im posting.

Im trying to write a Plugin for MSN Messenger Plus plugin that changes the personal message like the 'What I'm Listening To' when you use Windows Media Player or Itunes.

I've seen a .NET plugin that changes the nick, but i'm wondering if anyone has found out how to change the personal message. Any .NET Language will be fine.

Thanks Tom

Its Okay!

I did look around and saw documentation for something called Toaster!

I thought this would bringing up a dialog box in MSN Messenger toasting to someone!

But the actual feature for the personal message is called Toaster, so its okay.

But please provide content if you like.

Thanks again

The calling process requires the SE_SHUTDOWN_NAME privilege in order to shutdown the system. Also see InitiateSystemShutdownEx()[^].
