How do you work out that kind of thing? Have you got books? If so, can you recommend any?

Thanks.

(sorry if this has double posted, something up with my connection)

You can also follow the simpler code like this if you are using .NET 2.0 (VS 2005)

SaveFileDialog dlg = new SaveFileDialog();<br />
dlg.Filter = "Text Files|*.txt|Comma Seperated Files|*.csv|All Files|*.*";<br />
if (dlg.ShowDialog() == DialogResult.OK)<br />
{<br />
     File.WriteAllText(dlg.FileName, txtContent.Text);   <br />
}

Hmm. I've never called this method before. It must call Flush internally. I've had mixed results closing or disposing the StreamWriter class without flushing first.

Thanks for the tip. Smile | :)

Sending messages over LAN

14-Nov-06 5:43

Are you writing each line on its own using the StreamWriter.Write method, or are you writing the entire contents of the textbox to the Write method? If you're writing each line on its own, then you need to use WriteLine, not Write.

I'm trying to create a restaurant point of sale system that has the ability to send messages (xml files) over a LAN. Basically I would like to send orders from a front desk/dining area to the kitchen. Can someone please point me in the general direction of what to look up in order to do so? I'm not familiar with LAN stuff at all...

Thanks

Hi,

.NET Remoting[^] should be a good start.

I totally agree, because someone said, how do I create a text editor it made me actually think about making one myself, and by asking specific questions, I got specific answers. So, yeah do not just ask for something. Analyze the problem, think about what you want it to do, try and figure things out (Microsoft Visual C# 2005 is great for this, if you hover over functions) then if you still have no idea, post a specific question.

mmmm buddy, I think you should really be using a database, instead of "sending" orders to the kitchen Smile | :)

WCF (or if you have to use old stuff: a WebService). Remoting is a posible solution if you want to add complexity and remove flexibility.

The database is obviously something that could be used on the server (kitchen side in your example I guess), though for a small test example storing XML will probably do. If you use a database, access it from business logic on the server side, do not access it directly from the client side.

There has been an alarming amount of questions from people who want others to do their (home)work for them. They put zero effort into solving, or even understanding, the problem themselves.

If someone does not attempt to solve their problem themselves, please DO NOT HAND FEED them the answer. The question "Can you send me code" has been used way too many times without any effort on their part.

By all means point them in the right direction, but do not do their homework for them.

Stupid Regex Issue

Jamie Nordmeyer13-Nov-06 4:59

13-Nov-06 4:59

OK, this regular expression works great with the System.Text.RegularExpressions.Regex object:

^\d{3}(-?)\d{2}\1\d{4}$

but bombs out when used with Javascripts (IE7) RegExp object. I'm not using any options (multiline, ignoreCase, etc.). Has anybody heard of issues with the IE 7 Javascript engine having issues with back references, or any other weird regex stuff?

Jamie Nordmeyer13-Nov-06 5:13

Never mind. I'm a dope. NEVER, EVER, forget that Javascript, like C/C++/C#, requires that \ be written as \\. Blush | :O

have you used the @ setting for the string or quallified the slashes?

Jamie Nordmeyer13-Nov-06 5:29

13-Nov-06 5:29

The @ setting doesn't matter in my case, as the Regex string is being written to client script for use by the Javascript RegExp object. Thanks for the thought, though. No, that's always the first thing I check. This was just me being a bone head and forgetting to use \\ instead of \. D'Oh!!! D'Oh! | :doh:

Forgive my ignorance, but if you're writing a script with C#, wouldn't the @ make it literal, thus be written as is?

"^\d{3}(-?)\d{2}\1\d{4}$" <= wouldn't work.

"^\\d{3}(-?)\\d{2}\\1\\d{4}$" <= would work

@"^\d{3}(-?)\d{2}\1\d{4}$" <= result is same as above

Jamie Nordmeyer13-Nov-06 9:22

13-Nov-06 9:22

No, you're right. When I said that the @ symbol wasn't the issue, I meant that my C# code is fine; the regex pattern is ^\\d{3}(-?)\\d{2}\\1\\d{4}$. However, this is written to my javascript as ^\d{3}(-?)\d{2}\1\d{4}$, and thus the \ charector is stripped from the string by javascript BEFORE it is passed to the RegExp object. My code had to be modified to use ^\\\\d{3}(-?)\\\\d{2}\\\\1\\\\d{4}$

OMG | :OMG:

I was hoping that was the problem. I was about to rumble through my c# books on regex Smile | :)

thanks

Jamie Nordmeyer13-Nov-06 9:26

13-Nov-06 9:26

Just think if there were another layer, and you had to write ^\\\\\\\\d{3}(-?)\\\\\\\\d{2}\\\\\\\\1\\\\\\\\d{4}$
