Why burden the app with regex? Someone else gave what is, in my humble aopinion, a much better solution using LastIndexOf(" ").

You're right.
Thank you John.

In my humble opinion, the LastIndexOf(" ") solution will fail in case of other white space characters or if the string contains one word only. In fact an expression like @"\S*(?=\s*$)" would be better as it matches the last non-whitespace character combination in the string.

The OP's example CLEARLY indicatedc spaces were being used to separate words in a TextBox. What other kind of whitespace characters did you have in mind?
First, using RegEx obfuscates the intent of the code, and slows it down besides. I can count on ONE HAND the number of people I know that would use RegEx over the much simpler construct of LastIndexOf(). As soon as new programmers learn that readability and maintainability is much more important than "clever code", we'll all be a lot better off. Sure, RegEx has it's place, but not for this problem.
A valid example of requiring RegEx is validating that an email address is properly formatted. But for finding the last word in a string of words separated by spaces? Not on your life.

Your post made me think of other white space characters such as Tab and NewLine (depends on how he gets the input string from the user). I'm aware that readability and maintainability is more important than clever code, and i wasn't trying to be clever. I just think a simple regex is much less in code than using LastIndexOfAny and handling the -1 return case.

It will be much more easy and simple to use 'lastindexof'
So you can use this:
string lastword;
int lastindex = str.LastIndexOf(" ")-1;
int len = str.Length;
if (lastindex == -1) //if there is only one word in the string
{
lastword = str;
}
else
{
lastword = str.Substring(lastindex, (len - lastindex));
}
//here str is the string from which last word has to be taken

Hey, I was wondering how I can send a file download after my class is complete.
I have a C# + ASP.NET site. I have a Button1_Click class. When that is run it copies some files, does some things and eventually creates a zip file. How do I send that zip file to the user as a download? E.G. I want it to
1) User clicks button
2) Server does what it needs to do
3) User gets a file download popup with the zip file that was created in step 2.
All I need help with is #3.
Thanks!!,
Anand
P.S. I've looked into Response.BinaryWrite but I'm not sure if that is it.

Hey now, we have a whole ASP .NET forum y'know.
But, from that one time when I used asp .net about 3 years ago, I think you can just use Response.Redirect, the web browser should recognise that its a file and not a web page, and start a download.

Hi there.
I have a TreeView in my project.
There are some nodes in it.
Now I want when user drags out a node to a folder, a text file creates in destination folder.
Do you understand what I mean ?
Can you help me ?
Thank you.

Y'know, I think I have a solution to your problem.
Step One: Create the text file in a temporary directory somewhere, and fill it with whatever you want.
Step Two: Add in something like this:
void TreeView1ItemDrag(object sender, ItemDragEventArgs e)
{
string[] stuff = new string[1];
stuff[0] = 'path to that text file you just made';
.
DataObject data = new DataObject(DataFormats.FileDrop, stuff);
.
this.treeView1.DoDragDrop(data, DragDropEffects.Move);
}
Windows will then move the text file from it's temporary home, to wherever the user dragged your node to.

Hi There,
I want to insert a row into a table which is displayed in datagridview.
The table is named "WireTbl" in "WireDb" database, and has 5 fields: Code, Street, Alley, Date and Time.
Would you please help me to write a correct INSERT command for this code:
Int32 x1 = System.Convert.ToInt32(textBox1.Text);//Code
String x2 = textBox2.text;//Street
String x3 = textBox3.Text;//Alley
DateTime x4 = System.Convert.ToDateTime(textBox4.Text);//Date
DateTime x5 = System.Convert.ToDateTime(textBox5.Text);//Time
cmd1.CommandText = "Insert into WireTbl("+ "Code, "+ "Street, "+ "alley, "+ "Date, "+ "Time, "+
") VALUES('" + x1 + "', "', '"+ x2+ "','"+ x3+ "','"+ x4+ "', x5)";
Tnx

use appropriate parameters to your command and change your command text according to parameter identification

") VALUES('" + x1 + "', "', '"+ x2+ "','"+ x3+ "','"+ x4+ "', x5)";
change to
cmd1.CommandText = "INSERT INTO WIRETBL(Code, Street, Alley, Date, Time) VALUES(@Code, @Street, @Alley, @Date, @Time)";
cmd1.Parameters.Add("@Code", SqlDbType.Int).Value = x1;
cmd1.Parameters.Add("@Street", SqlDbType.Varchar).Value = x2;
cmd1.Parameters.Add("@Alley", SqlDbType.Varchar).Value = x3;
cmd1.Parameters.Add("@Date", SqlDbType.DateTime).Value = x4;
cmd1.Parameters.Add("@Time", SqlDbType.DateTime).Value = x5;
cmd1.ExecuteNonQuery();
hope it helps

Thanks fort heloping me. I am using access database. Do I have to change Sql to Ole in the code you wrote me? For Example:
cmd1.CommandText = "INSERT INTO WIRETBL(Code, Street, Alley, Date, Time) VALUES(@Code, @Street, @Alley, @Date, @Time)";cmd1.Parameters.Add("@Code", OleDbType.Int).Value = x1;cmd1.Parameters.Add("@Street", OleDbType.Varchar).Value = x2;cmd1.Parameters.Add("@Alley", OleDbType.Varchar).Value = x3;cmd1.Parameters.Add("@Date", OleDbType.DateTime).Value = x4;cmd1.Parameters.Add("@Time", OleDbType.DateTime).Value = x5;cmd1.ExecuteNonQuery();

"String was not recognized as a valid DateTime." for this line:
DateTime x4 = System.Convert.ToDateTime(textBox4.Text);//Date
Then I changed DateTime to String:For example for this line:
String x5 = System.Convert.ToString(textBox5.Text);//
cmd1.Parameters.AddWithValue("@Time", OleDbType.VarChar).Value = x5;
but this time I got this error:
Syntax error in INSERT INTO statement.

Oh thanks alot it is a good start for me.I have to read it and test ur program myself.
But another question, How I can use a datagridview to show a table's content without puting datagridview object on the form? I want to define datagridview in my code.
Sourie

1. create DataGridView instance
2. Set it datasource to your DataTable or DataSet
3. if you need to show the grid just add it to container control like form or panel with method "containerControl to add".Controls.Add("your datagridview") ie.
form1.Controls.Add(myGrid);

Wow, Finally I wrote a program .
Now I know what's the exact meaning of adapter, connection, dataset, datatable, and command.
I will try your suggestion to use datagridview also.
