Thank you for your answer. Yes, I do use a connection string in my application, however I do not store it in App.config. It is contructed at run-time since the localtion of the database depends on where the users decide to install the applications. I will try to move it to App.config.
From what you are saying then, my client applications will only have to point to the location of the central server to find the Database and it will work just like if the database was locally installed. Did I understand correctly?
Do I need to change my C# code to manage multi-users vs single users?
Thank you for you help!

I have made a deployment project on Visual Studio 2005, but there is a problem - all the files and folders, and the welcome text of the installer contain Cyrillic text. When the installation runs all the Cyrillic text is displayed like white squares! How can i fix this problem???
Still learning...

Hello to all,
First, sorry for my english. 
I have an aplication where the user should write in a textbox a regular expression, then all the words that matches in an listBox should be selected, and it works fine, but if the user intruduces a bad regular expression (like *a instead of a*) it blows the all thing. How could i fix it.
here is part of the code:
////////////////////////////////////////////////////////////////////
string exp = textBox1_Tab3_Create6.Text;
Regex rexp = new Regex(exp);
//compara a substring de cada item com a introduzida e
//selecciona se for igual
for (int i = 0; i < listBox1_Tab3_Create6.Items.Count; i++)
{
string word = listBox1_Tab3_Create6.Items[i].ToString();
if (rexp.IsMatch(word))
listBox1_Tab3_Create6.SetSelected(i, true);
}
///////////////////////////////////////////////////////////////////
Thanks for any help

I guess by "it blows the all thing" you mean you get an exception because the regex is wrong?
Nothing easier to fix:
string exp = textBox1_Tab3_Create6.Text;
try {
Regex rexp = new Regex(exp);
}
catch(ArgumentException e)
{
}
regards

Hi All,
This has to be one of the most common things I'm encountering when looking at MSDN Examples.
I'm wnating to grab a list of the logical drives on my computer. Dead simple ... ?
So I looked up some examples and found this on MSDN (i've always used Directory.GetLogicDrive();) so I thought I'd give this a try.
using System;
class Sample
{
public static void Main()
{
Console.WriteLine();
String[] drives = Environment.GetLogicalDrives();
Console.WriteLine("GetLogicalDrives: {0}", String.Join(", ", drives));
}
}
Putting the line:
String[] drives = Environment.GetLogicalDrives();
Yields an error saying that drives doesn't exist in this context. How can such a simple example not work in my code? I'm Confused!!

There is nothing wrong with that line of code. You have to show a bit more of the code where you use this.

DOH! It was in a private method ... making that method public has fixed it.
I'm still very much getting my head around how to scope things in C#. I'm SO used to FoxPro (like 10 years worth of nothing but FoxPro) and that doesn't care what you do, like
x = 0
x = "boo!"
and it will just carry on ...

Then you have a lot more than just scope to get your head around...

Hi Again,
All i'm doing is:
private static List<string> GetMachinesDirectoryList()
{
List<string> DirectoryList = new List<string>();
string[] drives = Directory.GetLogicalDrives();
return DirectoryList;
}</string></string></string>
Yet neither line works for me ... If I add a watch I just get an out of context error. All the examples out there I can find do *exactly* the same thing string[] drives = Directory.GetLogicalDrives(); so how come this doesn't work in my code?
Cheers,
Jammer

Are you getting a compiler error or a runtime error? The method should look like this:
private static List GetMachinesDirectoryList()
{
string[] drives = Directory.GetLogicalDrives();
return new List<string>(drives);
}

System.IO.Directory.GetLogicalDrives(), I believe. Your problem is probably that the example assumes a using statement.

I Pete,
I can't remember that particular issue! There have been so many lately they are all blurring into one mass of "eh?" heh heh ...

Hi,
if you feel you are running from one problem to the next, and not gaining much
insight in the process, I strongly recommend you go to a book store, look into
some introductory or tutorial programming books, and choose and buy and study one,
chapter by chapter. That will teach you the basics in a logical order, provide
examples and show the right way to do things.
I am not going to recommend a specific book, since I believe it very much depends
on your programming knowledge in general and the writing style you prefer.
I do like most Microsoft books so far.

Sound advice. I think I'm picking up a lot of stuff fairly quickly. A lot of the time it also comes down to confidence. I have too often already quickly based a mail out on codeproject only to fix the problem seconds later.
I'm currently reading up on WPF and XAML/Blend/Expression as that is what I'm working with at the day job at the moment.
I think I'm doing okish. I've got to the point with my app in 1 month that took 6 months in FoxPro.
Code Project has been incredibly helpful.

haha ... there have been so very many issues!
