Since this was related to programming and my previous post, if you wish to think so because of the title, I figured this is the best place to rant about it. I've seen too many people get ripped in the Lounge for ranting about some programming issue because others thought they were attempting to conceal a programming question as a rant. Since the rant post icon is available here, I figured it is within the scope of the forum. Those who don't visit the Lounge may not know me here because I don't program often. Considering my last question in here before "Part I" was over a year ago, I can hardly be accused of abusing threads. Having said that, I shall endeavor not to do that again. I would suggest to Chris to disable rant or joke posts in programming forums if they are not tolerated at all.

It's more of a pain trying to figure out what on earth you are talking about.
Use the best guess

Still trivial.

I need to calculate total grades for students with files and arrays. user first enters course they are calculating grades from. all data files use this course file as part of their name. Outer loop to read the records from the master name file. Inner loop or loop insidefunction to read the records for each student.When processing the records from a student file each one should be done separately and not assumed they are grouped in any particular order.
Program reads a record, decides what category it is in updates the running total for that category. Once the entire file has been read, you can compute the average for each category based on the number of items that should be in that category, which may be more than the number of records in the file for items turned in.
I am horrible and I mean horrible at this and I have literally put in about 35 hours into trying to make this work and this is my 8th program I have redone and really need any guidance on what I should do or if I should restart again or what I am doing wrong.
I am receiving errors on line 29 "unexpected symbol 'while' in class,struct, or interface member declaration and
line 29 and 32 "unexpected symbol ')' in class, struct or interface member declaration"

I suspect that much of your problems comes from not matching your braces. I would start by putting the left-braces ( { ) where they belong so you can see them more easily. Then perhaps, print the code and draw lines to match them up so you can more easily see the structure of your code.

The first thing I notice here is that you have got a closing braces wrong.
For e.g.
while (!reader.EndOfStream) {
string line = reader.ReadLine ();
Console.WriteLine (line);
}
}
The second brace above is incorrect and should be removed.
Remove the brace, build again and check what errors you get after the build.

ok thank you that made the errors go away but now when I try to test the code after I press enter this shows up on the screen...

A few tips.
1. Perhaps it's better to take the logic out of the GradeBook class that contains the main method (= entrypoint of your application.) Mostly Visual Studio will create a file Program.cs with the main method in there.
2. Always use {} even for single line statements after the control statement. (there are some who don't mind this, but I find it best practice to do so)
3. write //end ... (for, if while) after each ending curly bracket (}) that indicates what it ends.
4. in Visual studio you can highlight matching braces. put your cursor on a start bracket ({) and scroll down to the matching one. (if you did #3 you'll occasionally notice that when there are missing brackets you have an //end for written instead of the if statement you started from)
5. I think it's best you take a step back and try to translate the necessary functionality into technical solution (what classes do you need, what methods, write some pseudocode).
In your code after the main method you seem to start a new method, but it is not declared. The part between main and GetStringArray is not what it's supposed to be.
Hope this helps.

Hi,
I am trying to export gridview data to excel. It is working fine except the first row in the excel is blank.
The code i used for the excel is shown below:
HttpContext.Current.Response.Clear();
Response.ClearContent();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=GrpFile.xls");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
HtmlForm frm = new HtmlForm();
gvCampGrp.Parent.Controls.Add(frm);
frm.Attributes["runat"] = "server";
frm.Controls.Add(gvCampGrp);
frm.RenderControl(hw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
I also included the following code.
public override void VerifyRenderingInServerForm(Control control)
{
return;
}
How to export data to excel without making its first row empty?
Please help.

i removed the htmlform code from the section and now it worked fine.
HttpContext.Current.Response.Clear();
Response.ClearContent();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=GrpFile.xls");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
gvCampGrp.RenderControl(hw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
and
public override void VerifyRenderingInServerForm(Control control)
{
return;
}

Create a transparent[^] form, and make sure that the border isn't transparent.

but that transparent form will recieve click events rather than desktop itself, right?

Wrong. Alternatively, you can set a specific color to become transparent.
using System;
using System.Drawing;
using System.Windows.Forms;
using System.Collections.Generic;
static class Program
{
public static void Main()
{
using (var f = new Form())
{
var b = new Button();
b.Text = "Hello world";
f.Controls.Add(b);
f.BackColor = Color.Red;
f.TransparencyKey = Color.Red;
f.AllowTransparency = true;
f.WindowState = FormWindowState.Maximized;
f.ShowDialog();
}
}
}

well using ur technique if i draw something on form that is red, it wont appear.

I'd recommend using a different transparency-key than red. Pick one that's not in use yet.

i am making an app that will display lots of light bulbs of different colors, so i dont think this transparency key thing will work.
