I tried it the traditional C# way of:

public String test
{
get
{
return "hi";
}
set
{
button1.Content = value;
}
}

But the WPF designer didn't seem to be able to detect it, although I could still do it programatically. What's the proper way of declaring a new property for a control? Thanks.

I want to learn how to use a local (stored on the computer not the internet) database to store information for my application. I did some searching and found articles, but they seemed to have no relation to a learning sequence. I have C# programming experience but no database experience, where should I start and what articles should I read? Thanks.

In Windows Vista, the privilege of the application can limit many parts such as registry access etc. Is there a way to set the provilege level to "Run this program as an administrator" when you click build in Visual Studio? Thanks.

Like in unmanaged code when you type that it says "Press any key to continue..." Thats not what I want it to do but its an example. The school has cmd.exe blocked but I need it to run java commands in my program. Thanks.

Process.Start("pause"); gives an error :S.

In C++, you do system("command here"); How do you do this in C# without running cmd.exe with an argument? Thanks.

I did some reading about embedded resources but they all dealt with pictures and other runtime functions. How do I copy the file from a resource? Thanks.

ShellExecuteEx works, thanks. What about the command for running an applet?:confused:

java MyClass.class in command prompt will start an application in the console window. How do I start an Applet in the default Applet window? Also, how do I run a command prompt script from a .net application (p/invoke???)? Thanks.

What would be the initial value of the property?

}// close inner if statement
cat.Location = newLoc;
MessageBox.Show("" + i);

Should be ("" + i.ToString());

I see... thanks.

No, whats that :S?

I've been using properties for quite some time, and it was until today that a question came to me: what's the difference between using a property and a variable? I know properties are better practice, but still... just wondering :).

public int Number
{
get
{
return this.number;
}
set
{
this.number = value;
}
}

vs

public int number = 0;

You always can, its the .exe in the bin\Debug\ folder...

I messed around with it a bit and ended up using SendKeys. I know this isn't the best method, but its the only one I tried so far that works. Basically,

try
{
dataGridView1.BeginEdit(true);
String tempText = Clipboard.GetText();
tempText = tempText.Replace("{", "{{}");
tempText = tempText.Replace("}", "{}}");
tempText = tempText.Replace("{{{}}", "{{}");
tempText = tempText.Replace("(", "{(}");
tempText = tempText.Replace(")", "{)}");
tempText = tempText.Replace("+", "{+}");
tempText = tempText.Replace("^", "{^}");
tempText = tempText.Replace("%", "{%}");
tempText = tempText.Replace("~", "{~}");
SendKeys.Send(tempText);
SendKeys.Send("{DOWN}");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n\nThe previous value was restored.", Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error);
dataGridView1.CurrentCell.Value = previousValue;
}

I recently made a program for organizing marks and realized that it is slow and repetitive to type the same teacher's name 20 times for students in the same class. I chose to add a little copy and paste feature when the user presses ctrl+v and the active cell becomes the contents of the clipboard. Here is the snippet:

else if (e.Control && e.KeyCode == Keys.V)
{
if (Clipboard.ContainsText() & dataGridView1.CurrentCell.OwningColumn.Index == 4)
{
dataGridView1.CurrentCell.Value = Clipboard.GetText();
}

            // If its the last row, add another row
            if (dataGridView1.CurrentCell.OwningRow.Index == nUD\_counter)
            {
                dataGridView1.Rows.Add();
            }
        }

What I'm having problems with is the last part, where I add another row (Microsoft made it so it would automatically add a row if the cell is edited by the user, but not programatically. The problem is that when I add the new row, it places it above the row which I just pasted info into such that:

col1 col2
a b
<-blank line where I press ctrl+v->

It becomes

col1 col2
a b
<-blank line where I press ctrl+v->
hi

How can I fix this? Also feel free to make suggestions on my code. Thanks in advance.

using (StreamWriter sw = File.CreateText(fileName))
{
sw.Write(data);
}

using (StreamReader sr = File.OpenText(fileName))
{
String contents = sr.ReadToEnd();
}

Haha, I tried reading the IComparer page before but didn't quite get it. This one was much easier to read, thanks!
