You can do it one of two ways:
string[] pathParts = myPath.Split('\\');
and you'll end up with an array of strings that represent the various components.
Or, you can use the various System.Path.IO.GetXXXXX methods.

Hi all,
I am having difficulties formatting the output of the following writeline statement.
Console.WriteLine("CYLINDER1:\n RADIUS:"+ t1.Rad+"\n LENGTH:"+ t1.Len+"\n AREA:"+ t1.findArea()+"\n VOLUME:" + t1.findVolume());
Both radius and length are of type double, and both methods, findArea() and findVolume(), are defined as follows:
public double findArea()
{
return 2*(Math.PI * radius * radius) + 2*(Math.PI * radius * length);
}
public double findVolume()
{
return Math.PI *(radius * radius *length);
}
I would like the outputs of Area and Volume to have 4 numbers behind the decimal place. Please take a look and see what I'd have to change to make it output what I want. Thank you in advance for your help.

I was not sure you meant 4 numbers 'before' or 'after' the number when you mentioned 'behind'.
To set 4 numbers before the decimal use -
Console.WriteLine("{0:D4}", t1.findArea());
To set 4 numbers after the decimal use -
Console.WriteLine("{0:N4}", t1.findArea());

Hi Abhinav S,
Thanks for responding however, I already thought about doing what you have suggested prior to posting this question. The reason I did not go that route is because if I had decided to use placeholders to hold the incoming data, I'd have to have a writeLine statement for every variable within my original write statement. As you can see in my post I did not use any placeholders at all in my writeline statement. All I used are the string literals for AREA and VOLUME followed by t1.findArea() and t1.findVolume() etc. Is there any way I can still have the outputs I'm looking for without having to resort to having a writeline statement for each variable within my original writeline statement? Thanks again for your help.

Console.WriteLine("CYLINDER1:\n RADIUS:"+ t1.Rad+"\n LENGTH:"+ t1.Len+"\n AREA:"+ t1.findArea().tostring(".0000")+"\n VOLUME:" + t1.findVolume().tostring(".0000"));
is that what you want?

can anyone help me to get window using process thread
SUCIL
|
|
|
|
|
You can use this to get an instance to the current thread:
Thread _currentThread = Thread.CurrentThread

Are you looking for the main form in your own application ?
A main window in a different application?
Is the other process a .NET application?
Please explain
|
|
|
|
|
I assume that you want to get the window handle from a thread id. To do that, I would:
- Pass the thread id to GetProcessIdOfThread() to obtain a process id
- Because a process can open multiple windows, you need to return a collection. Iterate every window, getting their process ids. If it matches the id from 1., then add the window handle to the collection

Basically lets say you have 3 items in an array[]
is there a way to do something like this
for (int i=0; i< array[].length; i++)
{
string Name + i = blahblah.tostring();
basically so I would have 3 strings
Name1
Name2
and Name3
|
|
|
|
|
Not that I konw of.
You could use a dictionary<string, string> where the key is the "name
of the variable".
something like:
Dictionary<string, string> blah = new Dictionary<string, string>();
for (int i = 0; i < array[].length; i++)
{
blah.Add("Name" + i.ToString(), "blablablah");
}
|
|
|
|

If they are fields/properties instead of local variables you could do something like that with reflection, but you really shouldn't.

Well what I was thinking is since my current code is giving me an issue with resetting the dataset inside a foreach loop I was gonna do the following to populate a tree view.
string[] AuthorNames = new string[bookdbDataSet.Tables[0].Rows.Count];
int row=0;
foreach (DataRow Row in bookdbDataSet.Tables[0].Rows)
{
AuthorNames[row] = Row["AuthorFirst"].ToString() + " " + Row["AuthorLast"].ToString();
TreeNode [DYNAMIC NAME HERE] = new TreeNode(Row["AuthorLast"].ToString() + ',' + Row["AuthorFirst"].ToString());
rootNode.Nodes.Add(tn);
row++;
}
for (int counter = 0; counter < AuthorNames.Length; counter++)
{
string[] splitarray = null;
string Aname = AuthorName[i].tostring();
splitarray = Aname.split(" ");
bookListTableAdapter.FillByFirstandLast(bookdbDataSet.BookList, SplitArray[1].ToString(), SplitArray[0].ToString());
foreach (DataRow ChildRow in bookdbDataSet.Tables[0].Rows)
{
TreeNode child = [DYNAMIC NAME HERE].Nodes.Add(ChildRow["Title"].tostring());
}
[DYNAMIC NAME HERE].nodes.add(child);
}
So basically I get all the unique author names first and put them in an array
Then I fill the dataset one at a time for each author and then run a foreach to get the titles and then I assign them to the node of the Rootnode's dynamic name
|
|
|
|
|
Well clearly you can't do that, even if "dynamic names" were possible they would go out of scope..
Idea 0: Why don't you just fill and array with them?
Idea 1: Couldn't you nest the loops? Then you would only need 1 temporary variable to hold the current TreeNode.
|
|
|
|
|
well, here is what i was originally thinking but of course I can't do the second fill with the foreach. Thats why I went a different route. I'm sure I'm doing this all wrong but hey I'm learning so what the heck...

Why can't you do that? As far as I can see you're not changing the collection that the foreach loops over
