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.

int startIndex = 6;
int Length = 4;
string MyString = "thisissomedatablahblahblah";
string SubString = MyString.Substring(startIndex, Length);

Hop that can help

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!

The Compare method doesn't support wildcards.

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

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()[^].

Hi Nish,
You probably get shocked when you know what his id means in English. It's currently in Vnese, and in English it means "f*ck your mom" ! However, I think he might be joking when he picked up this id for himself.

You can check out the ExitWindowsEx[^] function in the Platform SDK for the meaning of the parameter. You can also find the sample code from here:

Hi everybody!!!
I have a DataSet with only one DataTable in it.
The DataTable has many DataColumn and one of those is binded to a ComboBox.
Below the DataColumn...
DataColumn protocolloColumn = new DataColumn("protocollo");
protocolloColumn.DataType = System.Type.GetType("System.String");
carDataTable.Columns.Add(protocolloColumn);
...and the Binding
this.protocolloComboBox.DataBindings.Add(new Binding("SelectedValue", carDataSet, "car_models.protocollo"));

The ComboBox is populated with some string.
When I select a value from the combobox, this value is not stored in the dataset.
Can anybody help me?

Message Queue question (msmq)

Gibzon9-Jan-06 4:42

9-Jan-06 4:42

Ive built an client/server application where several clients are sending live data about itself to the server. Everything is working well on the local network using MSMQ. Im using private queues since i dont need any ack or transactions. The problem is i want everything online. So i changed the formatname to http and used the built in http support in msmq. This actually worked fine when i tried with a computer not behind a firewall or a router (win xp). But when trying to connect to a computer withtin a router (win2k3) it doesnt work. The message stays in the outgoing queue on the client. Ive set all the permissions and the port is of course open (i can enter the ip + /MSMQ/ and wont get an error).
Anyone know what could be wrong?

Or, if anyone have another idea how to do this it would be appreciated. Also, what i really want to do is to be able to recieve messages over http (instead of only beeing able to send them). Because as it is now, i can only put the message trough http, but must recieve them trough the local network using another format name. Please help Smile | :)

Custom date/time formating and string conversion

I'm trying display timestamps using the following format 20060109 152412Z (year month day hour minute second Z = zulu/gmt time). The closest I've got is to set the System.Globalization.CultureInfo.DateTimeFormat.FullDateTimePattern to "yyyyMMdd HHmmss" which does everything except the timezone change. In addition to not knowing how do to the timezone thing, convert.ToDateTime() won't parse strings in this format.

Create a DateTimeFormat object and set the custom format on that, then you can use it to format and parse strings.

For time zone convertsion, look into the TimeZone class.

I am. My main form constructor calls this code:

<br />
			System.Globalization.CultureInfo info;<br />
			info = System.Globalization.CultureInfo.CurrentCulture;<br />
			info = new System.Globalization.CultureInfo(info.LCID, true);<br />
			info.DateTimeFormat.ShortTimePattern = "HHmmss";//"HH:mm:ss";<br />
			info.DateTimeFormat.LongTimePattern = "HHmmss";//"HH:mm:ss";<br />
			info.DateTimeFormat.ShortDatePattern = "yyyyMMdd";//"MM/dd/yyyy";<br />
			info.DateTimeFormat.FullDateTimePattern = "yyyyMMdd HHmmss";//"MM/dd/yyyy HH:mm:ss";<br />
			System.Threading.Thread.CurrentThread.CurrentCulture = info; <br />
<br />
			DateTime test = Convert.ToDateTime("20060109 170501");<br />

The converions call on the last line throws a System.FormatException: {"String was not recognized as a valid DateTime." }
