Okay, I fixed the defined variables...but now I get a bunch of errors saying invalid "{"'s and "}"'s after the methods and stuff plus "expected class, delegate, enum, interface, or struct" for the voids. And this is what I've got for coding:
using System;
using System.Collections.Generic;
using System.Text;
namespace Program5
{
class Program
{
const double DEPINS = 25.50;
const double TAX = .23;
int dep;
double grossPay, hourRate, hourWorked, deduct, netPay, depIns, tax;
static void getData()
{
Console.Write("Hours Worked: ");
hourWorked = Double.Parse(Console.ReadLine());
Console.Write("Hourly Rate: ");
hourRate = Double.Parse(Console.ReadLine());
Console.Write("Dependents: ");
dep = Int32.Parse(Console.ReadLine());
}
static void calcNet()
{
if (hourWorked >= 40)
grossPay = Math.Round(1.5 * hourRate * hourWorked, 2);
else
grossPay = Math.Round(hourRate * hourWorked, 2);
depIns = dep * DEPINS;
tax = grossPay * TAX;
deduct = Math.Round(depIns + tax, 2);
netPay = grossPay - deduct;
}
static void dspData();
{
Console.WriteLine("");
Console.WriteLine("Hours Worked: {0,9:n}", hourWorked);
Console.WriteLine("Hourly Rate: {0,9:n}", hourRate);
Console.WriteLine("Dependents: {0,9}", dep);
Console.WriteLine("Gross Pay: {0,9:n}", grossPay);
Console.WriteLine("Deductions: {0,9:n}", deduct);
Console.WriteLine(" ---------");
Console.WriteLine("Net Pay: {0,9:c}", netPay);
}
static void Main();
{
getData()
calcNet()
dspData()
}
}
}

this still has problems.
murtle3 wrote: static void dspData();
remove ';' after the function name.
murtle3 wrote: static void Main();
{
getData()
calcNet()
dspData()
}
remove ';' after Main() and add ';' after all the function calls.
after all this is done you should note that you are trying to access the class variables from static method. this is not possible.
a static method can access static variables. what you should do is make the variables static (not a good way of programming), but it should help you run the program.
instead of:
murtle3 wrote: int dep;
double grossPay, hourRate, hourWorked, deduct, netPay, depIns, tax;
try the following:
static int dep;
static double grossPay, hourRate, hourWorked, deduct, netPay, depIns, tax;
hope this helps.

Alright, I got it to work. Thanks a lot guys for your help!

You should use tryparse to read lnes, in case someone enters text instead of a number. You have not pasted the whole program, b/c there's nothing modular about this, it's all one method.
murtle3 wrote: nt dep;
double grossPay, hourRate, hourWorked, deduct, netPay, depIns, tax;
This is bad practice, declare variables as you give them values, not in a bunch at the top. If your teacher tells you to do it this way, tell him that C required this, but C# does not, and doing it only increases the scope of your variables, making debugging harder.

Hi,
I have a RichTextBox with some information about colors in the text stored as Rtf. Now I'd like to remove for example first 1000 chars from the text without loosing information about colors in rest of the text. Is it possible?
Thanks
Pawel

You should be able to use the Select[^] method to select the text you want to remove, then set the SelectedText[^] property to String.Empty (or "").
Take care,

You can set the path to the defragger under the following registry key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\DefragPath
The default value specifies the path and usually defaults to %systemroot%\system32\dfrg.msc %c:
You can see how Windows registers it's defragger in the file C:\Windows\Inf\dfrg.inf

Can someone help me understand why sr is being viewed as a local variable to the if statement in the finally clause.
the exact error I'm receiving is: "Use of unassigned local variable 'sr'"
As I said, everything is fine until the finally clause.
Thanks for the help!
ArrayList files;
StreamReader sr;
try {
sr = new StreamReader(args[0]);
do {
files.Add(sr.ReadLine());
} while (sr.Peek() > 0);
}
catch (Exception ex) {
MessageBox.Show(ApplaunchErr + "reading the .cfg file!\n" + AppClosing, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
Application.Exit();
}
finally {
if(!(sr == null))
sr.Close();
}

You need to explicitly set it to null and create a new instance of the ArrayList like so:
ArrayList files = new ArrayList();
StreamReader sr = null;
Take care,
Tom

It's not.
Payrok wrote: the exact error I'm receiving is: "Use of unassigned local variable 'sr'"
That's because the code preceding that statement doesn't guarantee that the variable has been assigned a value. If the creation of the StreamReader causes an exception, the code will exit the try block before any value has been assigned to the variable.

I'm not going to comment on the problem because you have already received two perfectly good answers. I do have a question though. Why do you not use if (sr != null) instead of if (!(sr == null))? The first is more readable.

Thanks for bringing that to my attention. There's a good reason for it actually, and it's because I do a lot more VB.Net development than C#. I'm more used to having to do stupid things like: if Not sr is nothing then ... end if
So it affects the way I structure things in C#. Thanks for the replies, I never realized I had to set an object to null like that to keep it in scope.

The variable is not out of scope, it just was not initialized.

It's not really keeping it in scope. It's just that the scoping of the compiler means that it can't really do an operation in a block on a variable if it thinks that it hasn't been initialised. I've lost count of the number of times I've been kicked in the butt by this one.

Hi,
Is it possible, my means of registry entries etc to launch the default Defragmenter in Windows. For example, users of OO Defrag can set this as the default, and can be launched as the default instead of the Windows defragmenter.
Thanks, Andrew.

Hi again... always fighting with my installation...
Now everything works fine... I only have 1 other little detail: I'd like to let the end user choose whether install or not SQL Server Express.
If I put it in the prerequisites and the users cancel the install of SQL Server. also my app doesn't get installed...
Is there a way? I googled around but seems like it's still not possible...
Life is not short... the problem is only how you organize yourself

Hi all,
I'm working on client-server application
While sending data from server through Socket class,
my client calls the callback function correctly but the problem rises when it gets hang at Client.Receive(buffer[])
in debug mode, when i repost message from server to client, it resumes the code from Client.Receive
what should be the reason, any idea?
thanks

If you are making a blocking call then it is working perfectly.

Hi friends,
How we can create a tearable-tab in C#? Means, suppose we have 2 tabs in a window/dialog. The user can be able to detach a tab from its parent window/dlg.This kind of tab implementation is called tearable-tab(I heard some term like "tab to window extension").
Hope some one can help me.Thanks in advance.
Thanks buddies

I'm new to C#. Can any one give me the code that implement tearable-tab?
Thanks in adavance.

First, read the post at the top of the forum titled "how to get an answer to your question", pay attention to item #2.
Second, what about the information Patrick Sears gave you? That should provide a solution for you.
