You can't be serious? You don't know C# at all and you're expected to bang out a complex site like this? Guy, you just asked "how do I build a house" and you've never even seen a hammer let alone nails and a 2x4.
You have absolutely no hope of completing this assignment within a year. Forget the C# language. If you can't work out how the database model is going to work, you can't write a single line of code that's going to mean anything.

my project includes:
- web based helpdesk for the end users.
-we have more then 1000 end users in our company.
-the helpdesk should enable users to lodge in any query or complain about having problem with their harware, eg, if the printer is not working.
-if users can not login to the system
-forgot their password or wants their password to be resetted and so on.
-they should be able to add their name, Id number, department,email address,date and time. Also there should be a column for official use only in which the IT administrator will fill in their name, the solution of the problem and the date and time it was fixed
-their should be a submit button which sends the copy of the form to the IT administrator. Then the IT administrator will have to fill in the official column and the form will be saved i the system for future refernce.
i am trying to use C# for the first time for this project.
Can someone tell me how to start with this project since this is my first project after i have joined this It department this month.
Just posting the original message, in case anyone is curious. Sadly, the people who ask us to do all their work for them, first get angry ( check ), then lie ( check ), then delete all their posts. I do hope this guy either quits his job, or has the sense to take our advice, but either way, if he deletes it and people wonder what all the talk was about, here it is.

Well, you've got some of the specs there, but you haven't got a working design. Obviously, only an idiot would jump in and try and code this thing without doing any real analysis or up front design, so I'd expect you to pull together several use cases, acceptance criteria, functional and technical designs, long before you even think to open a code editor. You have done this haven't you?

I have an asp program I need to print a receipt out from a button. Does anyone know how to print a receipt client side. I can do a crystal report, gridview, etc. It's a hosted app so it needs to be client side.
Thanks.

ASP doesn't use .NET at all, if you mean ASP.NET, then you want the ASP.NET forum. If you mean ASP, you want the web dev forum.

Hi, I’m trying to get some objects to move around in a 2d array of lists, but the program keeps exiting with ‘System.InvalidOperationException’ and “Additional information: Collection was modified; enumeration operation may not execute.”
I’m pretty sure that this is the part of the code causing all the problems-
public void cycleThroughList()<br />
{<br />
for (int x = 0; x < GridDimention; x++)<br />
{<br />
for (int y = 0; y < GridDimention; y++)<br />
{<br />
foreach (Microbe i in theWorld[x, y])<br />
{<br />
i.Talk();<br />
Update_Position(i);<br />
<br />
}<br />
}<br />
}<br />
}<br />
<br />
public void Update_Position (Microbe m)<br />
{<br />
if (m.sX != 0 & m.sY != 0)<br />
{ <br />
theWorld[m.positionX, m.positionY].Remove (m);<br />
theWorld[m.positionX + m.sX, m.positionY + m.sY].Add (m); <br />
}<br />
<br />
m.Talk();<br />
}
Where ‘Talk’ is a method that writes to the console the coordinates of the Microbe object, and the ‘int sX’ and ‘int sY’ are the modifications to the objects location on the array.
Do you guys have any idea how to fix this?
I really appreciate any advice you can give me!

The error means what it says. You cannot modify a collection while you're using it in a foreach, you need instead to write standard for loops.

I got an Image_click that makes an image become another image.
I want it to increment each time I click on it.
I got the increment right, the image changer right.
But the image_click just won't work twice.
Is there any function or method I can use?

What on earth do you mean ? what happens ? Perhaps you need to post code ?

Well... Code won't help.
The clicking procedure works fine.
And the declaration of the image is fine too...
Still wanna see?
private: System::Void TS11_MCli(System::Object^ sender, System::Windows::Forms::MouseEventArgs^ e) {
Tsn11 = Tsn11 + 1 ;
if (Tsn11 = 0) { this->TS11->Image = Image::FromFile("C:/GamePics/NOTILE.png");}
else {
if (Tsn11 = 1){ this->TS11->Image = Image::FromFile("C:/GamePics/GREEN.png");}
else {
if (Tsn11 = 2){ this->TS11->Image = Image::FromFile("C:/GamePics/GRTRE.png");}
else {
if (Tsn11 = 3){ this->TS11->Image = Image::FromFile("C:/GamePics/ROAD.png");}
else {
if (Tsn11 = 4){ this->TS11->Image = Image::FromFile("C:/GamePics/WALL.png");}
};
};
};
};
};
};
};
This was the clicking function.
When I click first time, the image switches to GREEN.png
When I click second time, the image stays as GREEN.png

Hi Everyone,
I am using button's obj in datagridview and set the flag as true to show the text value of the button (Name of the Button). If user clicks on the button, its changes the button’s name based upon the criteria. I am doing very simple code here.
I set button’s name as “buttonColumn.UseColumnTextForButtonValue = true;”
Now If I want to change the value with following settings. It did not work it out.
dataGridView1[e.ColumnIndex, e.RowIndex].Value = "America"; It is still taking "Name"
Can you please help me on this?
private void CreateButtonColumn()
{
// Initialize the button column.
DataGridViewButtonColumn buttonColumn = new DataGridViewButtonColumn();
// Add the button column to the control.
buttonColumn = new DataGridViewButtonColumn();
buttonColumn.Name = "Name";
buttonColumn.Text = "Name";
buttonColumn.Width = 110;
buttonColumn.UseColumnTextForButtonValue = true;
dataGridView1.Columns.Insert(0, buttonColumn);
dataGridView1.Rows.Add(2);
dataGridView1.CellClick += new DataGridViewCellEventHandler(dataGridView1_CellClick);
}
void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (Convert.ToInt32(e.ColumnIndex) == 0)
{
dataGridView1[e.ColumnIndex, e.RowIndex].Value = "America";
}
}
Thanks.

I've not tried this but from your code, an obvious thing to try would seem to be
void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (Convert.ToInt32(e.ColumnIndex) == 0)
{
((DataGridViewButtonColumn)dataGridView1.Columns[e.ColumnIndex]).UseColumnTextForButtonValue = false;
dataGridView1[e.ColumnIndex, e.RowIndex].Value = "America";
}
}
Hope this helps.

Thanks. This is very good one. Just to mention one thing here. Its changes all the rows with new value "America".
I want to updates the same cell where was cliked.

Thanks

Ah! 
Well, it was worth a try.
I have searched through my own code for examples of using a DataGridviewButtonColumn and all of the examples I found used the button click to load a data entry form to get the required data. on return from the data entry form they used the following syntax to set the value(s) entered:
void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (Convert.ToInt32(e.ColumnIndex) == 0)
{
dataGridView1.Rows[e.RowIndex].Cells["Name"].Value = "America";
}
}
which is setting the value of the appropriate Cell in the underlying DataGridViewRow.

I'm passing a delegate to unmanaged code, and the unmanaged code calls back into managed code.
I'm getting a mysterious "buffer overrun" error, and I wonder if the problem might be that I must pin the delegate.
But C# doesn't have the "pin_ptr" keyword. How would I do that?
EDIT: The pinned delegate must exist for the lifetime of the application, so the "fixed" keyword, which operates only on a small scope, would not be feasible.
FIX -- The buffer overrun error was caused by a mismatch of calling conventions. I simply applied the following attribute to my delegate, and that fixed the problem:
[UnmanagedFunctionPointer(CallingConvention.Cdecl)]

In my experience, there is no need to pin a delegate, just make sure it stays alive for as long as any call backs are expected. I believe the internal marshaling takes care of tracking the managed function pointer (if it is moved), but if it is garbage collected you will get errors if the unamanaged code attempts to call it.

Hi
Does anyone know how to dispose backgroundworker completely and release all the system resources associated with it?
I called cancelAsync and then backgroundworker.Dispose(), even then it shows backgroundworker.IsBusy = true.
Please help

Just because it shows IsBusy = true, why do you think it's using resources ? What resources do you expect it could be using ( answer, close to none, unless it uses something explicit, like Bitmaps, which you should have cleaned up explicitly yourself )

Calling CancelAsync just sets CancellationPending - it's up to you to check this property at apropriate places in your DoWork handler, and if it's set - set e.Cancel and return from the handler. Then, and only then will RunWorkerCompleted be called and the background thread terminated.
[Edit] Here's the source[^] that shows BackgroundWorker is implemented [/Edit]
