GetShortPathName

I would like to make "f.FileName" and "f.SelectedPath"  below the short paths, but I'm not sure what I need to declare...I keep getting errors beyond the syntax of my GetShortPathName(xx,xxx,xx)
so I figured I'd just let someone get the points...


Here's the current code that I want to change to shortpath:

        private void buttonBrowseFiles_Click(object sender, EventArgs e)
        {
            using (OpenFileDialog f = new OpenFileDialog())
            {
                f.FileName = this.textBoxBackupSelection.Text;
                f.Multiselect = false;

                if (f.ShowDialog() == DialogResult.OK)
                {
                    this.textBoxBackupSelection.Text = f.FileName;
                }
            }
        }

        private void buttonBrowseFolders_Click(object sender, EventArgs e)
        {
            using (FolderBrowserDialog f = new FolderBrowserDialog())
            {
                f.ShowNewFolderButton = false;
                f.RootFolder = Environment.SpecialFolder.MyComputer;

                f.SelectedPath = this.textBoxBackupSelection.Text;

                if (f.ShowDialog() == DialogResult.OK)
                {
                    this.textBoxBackupSelection.Text = f.SelectedPath;
                }
            }
        }

Not that we don't like points....  but there is a nice web site out there called pinvoke.net that has (almost all) of the Win32 API declarations already written for you!

graye - REALLY COOL SITE ... I will definitely use that more in the future!

it should be called more than anyone ever needed to know about p/invokes...

but where do I put this?

        [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        static extern uint GetShortPathName([MarshalAs(UnmanagedType.LPTStr)] string lpszLongPath,
        [MarshalAs(UnmanagedType.LPTStr)] StringBuilder lpszShortPath,
        int cchBuffer);

just put it inside a class somewhere, and then call it like any other part of the language/framework, such as

StringBuilder sb = new Stringbuilder(12);
GetShortPathName("c:\\somelongfilename.text", sb);

I get this error:
"the type or namespace name 'DllImport' could not be found (are you missing a using directive or an assembly reference?)

<aside: the grammar seems weird in the error, but that's what it says>


I sure thought this would be easier than it has turned out...

GRRR....

using System.Runtime.InteropServices;

needs to be at the top...



I sure with that there was a definitive guide to this.  My style of learning just doesn't seem to agree with the M$ documentation...
