you need more RAM. Most likely you have som repetion statement that dosn't exit giving you the exception when it has run for some time

I'm finally starting on C#.
Something I haven't had success with so far is reading/writing a table with the following XML format into a Hashtable object. (at this point in time the reading is the priority)
<br />
<table><br />
<item key="testkey">key value</item><br />
<item key="testkey2">key value2</item><br />
<item key="testkey3">key value3</item><br />
</table><br />
Both the key and the value are strings.
Any suggestions will be most welcome.
Happy programming!!

Put the xml in an XmlDocument object. The items will be the nodes in the child nodes collection of DocumentElement.

Hello everyone,
I'm creating program for File Monitoring using "FileSystemWatcher" class. The purpose is for notifying user with message box whenever there was some folder/file creation.
My question is how can we know about the author/owner of a new file/folder?

How do you mean ? If it's a word doc or something, it may have some metadata you can examine, otherwise, the only info that windows has is who was logged in when they created it, which would be at the moment you get your message. So, 'you just created a folder' is the best you can do, I'd have thought.

Hi, is there any way to get index/indices of a row where the content of a column is as specified. For example, the following table named "employee" contains 3 columns with 4 datarows.
[employee]
(emp_id)•(emp_name)•(salary)
00001 Johan 30000
00002 Joseph 35000
00003 Jack 28000
00004 Jane 32000
I'd like to find the index of a row where emp_name is "Joseph". Is there any way to get it? I've tried to use IndexOf() method to get it but it asks for a datarow as its parameter which i don't even know where it is in the table -_-"
DataTable dt = ds.Tables["employee"];
int i = dt.Rows.IndexOf(); <-- don't know what to put here.
Thank you so much.

<br />
DataTable dt=ds.Tables["employee"];<br />
DataRow[] arr=dt.Select("emp_name='Joseph'");<br />
textBox1.Text=arr[0].ItemArray["emp_id"].ToString();<br />
Worth noting, if you have several persons named Joseph you simply can not take the first one.
To obtain uniqueness it is better to work with the id-column.

The attribute gets converted also, but this forum removes it due to its xml-like format:
"<dataobjectmethod(dataobjectmethodtype.select, true)=""> _"
I thought Christian's on-line converter omitted it, but it was also obviously the forum ...

Wow - you can't even enter that format within a string literal - this should really be fixed.

You need to have two = signs if you are comparing:
if(textBox4.Text == "true")
{
}
You can use bool.Parse() if you need to convert a string to a boolean:
<code>bool myBool = bool.Parse("true");</code>

Thanks alot guys to the both of you.
[way off topic]
Sean i tried to find a way to send you a PM or Email to thank you personally for helping me yesterday. The way you showed me with the listview worked. I just had a problem with the button! But when you was talking about the "Item properties" i was thinking as i was reading that "how in the heck does he remember all theese properties and such". Then it just dawned on me! listview1.items is the exact same thing as going to the properties manager for that control and changing it their. Your just doing the exact same thing but w/o the point n click!. It opened my eyes up to what was actually going on in the code! I was so happy after finding that out i drove home as fast as i could to try to send you a pm telling you thanks but there wasn't a way to do so.
but anyways man thanks alot for the help i really appreciate it!

Single = is assignment
Double == is equality
if (textbox4.text == "true")
Boolean.Parse() to convert string to bool if needed
Sean just beat me to it by seconds!

A good coding practice is to set your constant on the left side of your operator, so the compiler catches mistakes. For example:
if ( "true" == textbox4.text )<br />
{<br />
}
will assure that you never are doing an assignment if you forget an = when you are intending to do a comparison. It's a good habit to get into.

My list is not being written to the outFile and I can't seem to figure out why. I will post the code but I am not sure how to paste it correctly. Any Help would be appreciated.
using System;
using System.IO;
namespace Seating_Chart
/*Write a C# program that will read a list of student
* names from a text fileand assemble a seating chart
* onscreen.When the program is first run it should
* display an empty seating grid.Then you should be
* able to change the seating of any student. Such
* as Row 1, Seat 4 and change it's name to "John Doe".
* Any changes made should be immediatley written to
* the file.You must use more than one class. */
{
class Students
{
static void Main ()
{
string [,] Students = new string [5,10];
char answer = ' ';
int row = 0;

return Students;
}
}
}
Sorry this is so messy.

Is there any exception being thrown? Did you try stepping through the debugger and seeing if the WriteLine method call actually executes?
