If it's only one PDF that is like this, then it means it's been saved as a read only PDF. If it's a problem with all external PDFs, then it's your code that's at fault.

Like it says in "how to ask a question", choose THE correct forum. THE means one, not two or more.

In a C# 2010 application, I have a string value that looks like the following:
"http://localhost:99/test/TestHome.aspx". I only want to obtain the part of the string that is "TestHome.aspx".
I have tried lots of string functions to obtain the "TestHome.aspx" part of the string with no success yet.
Thus can you tell me how to obtain the part of the string I am trying to access?

There are many ways you could accomplish this. You could use a regular expression (a sledgehammer to crack a nut). You could use string.LastIndexOf to find the last / and then do a Substring based off this, or you could do a string.Split and take the last item out of the array.
|
|
|
|
|
Use System.IO.Path.GetFileName("http://localhost:99/test/TestHome.aspx")
|
|

Good one!  My first impression was "that's a URL, not a path. It'll never work." Then I tried it. 
Cheers,

GetFileName is a good choice, but it does have the limitation of that it is actually doing more than is necessary to solve this particular problem. Why is that you ask? Well, when we deconstruct the method, it actually does the following:
public static string GetFileName(string path)
{
if (path != null)
{
CheckInvalidPathChars(path);
int length = path.Length;
int num2 = length;
while (--num2 >= 0)
{
char ch = path[num2];
if (((ch == DirectorySeparatorChar) || (ch == AltDirectorySeparatorChar)) || (ch == VolumeSeparatorChar))
{
return path.Substring(num2 + 1, (length - num2) - 1);
}
}
}
return path;
}As you can see, right at the top of the method, it's calling CheckInvalidPathChars to determine whether or not the path is valid. However, this is just a minor point - yours is a perfectly good solution, hence my 5.

Don't worry about anything, single one line code will solve problem,
i have complete program for you:
String s = "http://localhost:99/test/TestHome.aspx";
s = Path.GetFileName(s.Replace("/", "\\"));
Console.WriteLine(s);
Console.ReadKey();

GetFileName is a crap choice, doesn't sound very portable at all and there is a class dedicated to Uri handling already :P
Votes of 1 all around on this
Surely you'd do
var result = new Uri("http://foo.com/foo.aspx").Segments.Last();
|
|
|
|
|
So, an even less efficient method to retrieve this then. As the OP hasn't stated they are doing anything else Uri, it's kind of a waste when you end up with this method
public string[] Segments
{
get
{
int index;
if (this.IsNotAbsoluteUri)
{
throw new InvalidOperationException(SR.GetString("net_uri_NotAbsolute"));
}
string[] strArray = null;
if (strArray != null)
{
return strArray;
}
string privateAbsolutePath = this.PrivateAbsolutePath;
if (privateAbsolutePath.Length == 0)
{
return new string[0];
}
ArrayList list = new ArrayList();
for (int i = 0; i < privateAbsolutePath.Length; i = index + 1)
{
index = privateAbsolutePath.IndexOf('/', i);
if (index == -1)
{
index = privateAbsolutePath.Length - 1;
}
list.Add(privateAbsolutePath.Substring(i, (index - i) + 1));
}
return (string[]) list.ToArray(typeof(string));
}
} I'll be nice though. I won't award you a 1.

Path.GetFileName() is prefectly reasonable given the problem as described.
It describes the (apparent) intent, and so adds to the clarity of the code, which increases maintainability.
It is not necssarily the most efficient solution, but if done in response to user interaction, is probably plenty fast to not cause a performance issue.
|
|
|
|
|
A combination of the substring and IndexOf functions should be enough.
String.Split is the other neat option.
|
|
|
|
|
You could always use the System.Uri[^] class, which can provide much more information for you.
|
|
|
|
|
I'd use LastIndexOf and Substring, unless you actually want the extra validation of a path or URL parsing function.

Hello,
Try this:
Uri myUrl = new Uri("http://localhost:99/test/TestHome.aspx");
string pagina = myUrl.Segments.Last();

here is the problem which I come across with:
I want to get process name ,application name and it's window title name
with the code below
listView1.Columns.Add("CurrentProcess", 2000);
listView1.Columns.Add("CurrentProcessPID", 500);
listView1.Columns.Add("CurrentApplicationname", 2000);
listView1.Items.Insert(1,Process.GetCurrentProcess().ToString());
listView1.Items.Insert(2,Process.GetCurrentProcess().MainWindowTitle);
listView1.Items.Insert(3,Process.GetCurrentProcess().Id.ToString());
but when I run my code I get this result
system.diagnostics.process(currentApplication on ByPId.vshost) form1
I enter this code to run in a timer tick so I use other application in the middle of this running code but I just get the result above.
I would appreciate any commend

whenever your app does something, it IS the current process. Therefore, GetCurrentProcess() isn't going to help you getting information about other processes.
The Process class does hold what you need, however, be aware there are a number of system processes you are not allowed to get information about (You would get some kind of access violation when you try). An alternative route would be using WMI, probably with the exact same limitations.

thanks a lot;
I would like to write an application to run at the back ground( I mean do such thing except for itself);
do you recommend any thing?
|
|
|
|
|
I second what Luc said above.
Just as a hint, if you need information for the processes currently running on the local system, you could use the Process.GetProcesses static method.
But I have to ask... What's wrong with Windows Task Manager?

thanks for your comment;
I need it through a program ..
what I mean here is currently running application but not this application;
|
|
|
|
|
Well, an application is just that - a process. If you mean you need the processes that Task Managers displays in the Applications tab - another hint - that's a process that has a window, and if it has a window it should have a window handle.
Read about the Process class on MSDN, see what kind of properties and methods it has - the answer is all there (and here actually), so it's up to you to do the rest.

Hi
I'm experimenting with SQLite. The program complies and runs fine, except I can't see the actual stored ID's in my file1.db. Am I looking in the wrong place or doing something wrong here? I would appreciate any feedback. I basically store random text from texbox into file1.db
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.SQLite;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
private SQLiteConnection sqlcon;
private SQLiteCommand sqlcmd;
private SQLiteDataAdapter dataBase;
private DataSet dataSet = new DataSet();
private DataTable dataTable = new DataTable();
public Form1()
{
InitializeComponent();
createDataBase();
createDataTable();
}
private void createDataBase()
{
dataBase = new SQLiteDataAdapter();
}
private void createDataTable()
{
dataTable = new DataTable();
}
private void ExecuteQuery(string txtQuery)
{
using (SQLiteConnection sqlcon = new SQLiteConnection("Data Source=file1.db;Version=3;New=False;Compress=True;"))
{
using (SQLiteCommand sqlcmd = sqlcon.CreateCommand())
{
sqlcon.Open();
sqlcmd.CommandText = "create table records ( ID varchar(255))";
sqlcmd.CommandText = txtQuery;
sqlcmd.ExecuteNonQuery();
}
}
}
private void button1_Click(object sender, EventArgs e)
{
string txtQuery = "INSERT INTO RECORDS (ID) VALUES ('" + textBox1.Text + "')";
ExecuteQuery(txtQuery);
}
}
}
Thanks a lot
