I want to copy a font file to the fonts directory on windows vista, but currently i fail to get the right permissions.
Everytime I try to copy the font from its current folder to the font-directory (c:\windows\fonts) I get an "UnauthorisedAccessException"

My code looks like this at the moment:

            if (System.IO.File.Exists(fontPath))
            {
                FileIOPermission f2 = new FileIOPermission(FileIOPermissionAccess.Read | FileIOPermissionAccess.Write, "C:\\Windows\\Fonts\\");
                f2.AddPathList(FileIOPermissionAccess.Read | FileIOPermissionAccess.Write, fontPath);

                if (SecurityManager.IsGranted(f2) == true)
                    MessageBox.Show("Its fine!!");
                else
                    MessageBox.Show("No Permissions");

                try
                {
                    f2.Demand();
                    MessageBox.Show(fontPath);
                    System.IO.File.Copy(fontPath, destination);
                    //AddFontResource(fontPath);
                    //SendMessage(HWND_BROADCAST, WM_FONTCHANGE, (IntPtr)0, (IntPtr)0);

                }
                catch (SecurityException se)
                {
                    MessageBox.Show(se.ToString());
                }
                catch (UnauthorizedAccessException ex)
                {
                    MessageBox.Show(ex.ToString());
                }

            }

Thanks for your help

Do you have rights to access the Fonts folder?
Which line throws the exception? That would help knowing where the problem is.

Hi,

when I run code like that on Vista I am getting a DirectoryNotFoundException on C:\Windows\Fonts\ in the File.Copy() statement, although the folder is visible both in Windows Explorer and in Command Prompt, and I am running with admin privileges.

Confused | :confused:

Same code works for me in XP. I have the variables set as:

string fontPath = @"c:\test.txt";
string destination = @"C:\Windows\Fonts\test.txt";

Yeah, the problem is that i am using vista and a few things changed there. There are new security rules and i tried to do it the "good" way by asking the system for permissions.

Well, in my case the code works perfect in Vista as well (running as Admin). In your case, I see that you are checking the permissions for the file and not the destination folder. You can check the rights for that directory using DirectorySecurity class (I have never used it, hence not sure).

Is there a fast way to have a look on the privileges an user has for a folder? the windows explorer should have a way look them up.

Okultist17-Jun-09 2:46

I think its not possible to copy the Font file to the font-folder with out adminstrator status. so i decided to use an application manifest to run my program as a adminstrator on startup.

Put it either in the button he uses to click to the next page as a message box or on the form close and if you choose not to close handle there. Google is your friend.

It depends on what 'next page' is. If it is a Control descendant, write your code in the Click event handler.
Give them options for OK and Cancel, if they choose Cancel, just return from the handler before executing the code for next page.

The OP said it was a Windows Application, although he was talking about pages, so it could be that your reply might be more useful than the others.

Create a web service or get a external web service and add it to your project through "Add a webreference" option. Or you build your own, deploy it in IIS and add a web reference of that. now you can use it.

                {
                    using (sr2 = new StreamReader("c:\\input2.txt"))
                    {
                        file = new FileStream("c:\\output.txt", FileMode.Create, FileAccess.Write);
                        sw = new StreamWriter(file);
                        string line1;
                        string line2;

                        while ((line1 = sr1.ReadLine()) != null)
                        {
                            string[] temp1 = line1.Split(new char[] { ';' });

                            while ((line2 = sr2.ReadLine()) != null)
                            {
                                string[] temp2 = line2.Split(new char[] { ';' });

                                string final = temp1[0] + ";" + temp1[1] + ";" + temp1[2] + ";" + temp2[2] + ";" + temp1[2] + "-" + temp2[2];
                                sw.WriteLine(final);
                            }
                        }

                    }
                }
            }
            finally
            {
                sr1.Close();
                sr2.Close();
                sw.Close();
                file.Close();
            }
        }

I have created the above method to do some string management. The problem is that the outer while loops runs only for the first line in input1.txt and I don't know why. It's probably something simple but I can't find the solution.

Thanks...

Hi,

your code reads each stream once; i.e. for the first line of the first file, the entire content of the second file is read, then everything comes to a halt since sr2 has reached the end-of-stream condition.

if you want to have all combinations of lines from file1 and file2, then you should:
- either open the second file inside the while loop reading file1 (hence reopening it for every line of file1);
- or reposition sr2 at the beginning over and over again.

BTW:
Your try-finally construct will swallow any exception that may occur. I recommend you add catch(Exception exc) {Console.WriteLine(exc.ToString());} to visualize most problems that may (and sooner or later will) occur.

[CORRECTION]Exceptions don't get swallowed by finally blocks, they survive the try-finally construct and will have to be catched at some outer level [/CORRECTION]

Smile | :)

Or use ReadAllLines to read each file into a string array and then loop though with nested foreach loops.

Are you sure? Since the catch is missing, the finally block will be executed and the exception rethrown, no?

Hi,

my mistake, you are right, try-finally without catch does not influence exception throwing/catching at all.
