You haven't posted all your code. There are a number of variables that are not defined.
Post all of your code. I can't help you unless I can understand what you are doing.

ok..
my code to send info from my listview to a .xls file look like this:
string[] lines3 = System.IO.File.ReadAllLines("datainställningar.txt");
string path3 = lines3[0];
string text = textBox1.Text;
string namn = text + ".xls";
if (MessageBox.Show("Vill du skapa diagramet " + text + "?", "Mitt jobb",
MessageBoxButtons.YesNo, MessageBoxIcon.Question)
== DialogResult.Yes)
{
using (StreamWriter sw = new StreamWriter(path3 + namn))
{
for (int listIndex = 0; listIndex < this.listView2.Items.Count; listIndex++)
{
sw.WriteLine(this.listView2.Items[listIndex].Text + this.listView2.Items[listIndex].SubItems[1].Text + this.listView2.Items[listIndex].SubItems[2].Text + this.listView2.Items[listIndex].SubItems[3].Text);
}
Process.Start(namn);
}
}
But now it´s writes in only a1 cells in .xls, but i want it to write every subitems in each cell.
is it more clearly now??
tnx

AFAIK, there are 2 ways to create an Excel file in .NET.
1. Excel Automation. Allows you to programmatically control the Excel application. Requies Excel to be installed on the machine your application is running on.
2. JET OLEDB Provider. Allows you to connect to an Excel spreadsheet like a database and read/write data to it. Doesn't require Excel to be installed, only the JET driver.
Google either of these and you should find numerous examples to get you started.

Here is another method for generating Excel file from c# http://www.codeproject.com/dotnet/ExportToExcel.asp
|
|
|
|
|
This code will nevcer generate a REAL .xls file. You can generate a text .CSV (comma seperated values) file that Excel will import but it's not an .xls file.

I am not sure why MS decided to make CSV able to be imported into Excel by default. Quite a lot of people I know now, think that anything .CSV is an Excel file.

Because it was too bloody easy??

That shows you how much they really know about Excel and CSV files. Pretty much nothing, right?

Hi,
I would like to know how I can create a .csv file with today's date and a variable name.
I have the following:
int day = date.Day;
int month= date.Month;
int year= date.Year;
string str="hi";
int res="123";
Now I want to create a .csv file with the following name : 13102007_hi_123
I though of putting everything into a single string (lets' say, result) but then, how will the following code replace result with the string!? At present it creates a .csv file with the name of result
if (!File.Exists("c:\\code\\result.txt"))
{
File.Create("c:\\code\\result.txt");
}
Any help will be greatly appreciated...Cheers!
ALSO, can I add a heather that will be ignored by excel?

Separating the date into it's components isn't very useful. It's much easier to just format the date the way that you want: date.ToString("ddMMyyyy").
If you don't know how to concatenate strings and use variables instead of literal string values, you really need to pick up a beginners book and gets some basics down.

...I know how to concatenate strings! the problem is how I then refer to that "variable" when creating the .csv
|
|
|
|
|
...In case it is not clear...
int day = date.Day;
int month= date.Month;
int year= date.Year;
string str="hi";
int res="123";
string fileName = day + month + year + "_" + str + "_" + res
However, if I do : File.Create("c:\\code\\fileName.txt"), it creates a file with the name "fileName"...rather than the value of fileName
...any ideas?

Have you heard of string.Format()? Surely you must have seen it in the intellisence and wondered if it might be useful.

Have you thought of also concatenating the file path into the string too?

I didn't say that I thought it. I said it was what I (we) are normally accused of.

go like this:
File.Create("c:\\code\\" + filename + ".txt");
It's one of those obvious things that you can't see...like having to look a little right or left to see a dim star.

Colins sarcasm came from the fact that you knew how to do string concantenation, but when it came to giving a string representing a filename, you suddenly forgot how to do string concantenation!
Someone told you that "1+1=2" and you said "I KNOW!!", then when they asked you "what's 1+1?", you said you didn't know!

...and what "good" did sarcasm brought to the whole afair!? ...
I see your point Dave...
" but when it came to giving a string representing a filename, you suddenly forgot how to do string concantenation! "
It wasn't that I forgot,I just didn't know that it could be done like that...as you all might have gueesed by now I am new with this. Anyway, thanks to PIEBALconsul and David for the help

That's why I'm saying that you should start with the basics.
If you only can use something in a way that you've seen it used before, you have only learned to mimic others, you haven't really learned how it works.

Or strings.
Or meta information.

You need to buy a book on C# and read it. It's pretty basic stuff that anything in quotes, is a verbatim string. Your variable name becomes a variable name only when it's not in quotes.
@"c:\code\" + filename + ".txt";
