You somewhere access a variable that is set to null.
The debugger will show you which variable this is, just run the Debug build.

I had posted this message only after searching in google and msdn..

I have a windows based application in c#. On Windows explorer context menu i added one context menu item named "MyContext" . when the user right clicks on a file or folder, i have "MyContext" menu(This is the context menu item that i have added to the windows explorer context menu). When i click "MyContext" menu, i have to execute one application. In that application page load, i want to get the file or folder path that the user right clicked.

What you are talking about is called Windows Shell programming -not context menu Smile | :)

-. In CodeProject there is a very good section about Shell programming. i think you can find the anwer there. Click here[^].

I agree that this is windows shell programming. In that path is generated by args[0]. I have an application, which contains a tab control. inside the tabcontrol i am having a textbox. I am getting the string args[0] value from the program.cs file. I want to assign the string args[0] value to the textbox. How to assign that value to the textbox?
This is the program.cs file

static class Program
{
public static string pathkey;

public static string path
{
get
{
return pathkey;
}
set
{
pathkey = value;
}
}
[STAThread]
static void Main(string[] args)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
Form1 objform = new Form1();
try
{
Program.pathkey= args[0].ToString ();

}
catch (Exception ex)
{
}

Form1.cs
*********
In my form1 load, i am assigning the value to the textbox

txtLocation.Text = Program.pathkey.ToString();

But i am not able to get the value?

In registry i have the entry as C:\Documents and Settings\venkadeshp\My Documents\Visual Studio 2005\Projects\HCI_DMS ConsoleApplication\bin\Debug\HCI_DMS ConsoleApplication.exe %1 . But i couldnt find the file path in the string args[0] in the program.cs main function?

Thanks & Regards,
Venkat

Simple. In your Main method

 [STAThread]
static void Main(string[] args)
{
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new Form1(args[0]));
}

and in Modify your form constructor to this

Form1(string thePath)
{
    MyFileName = thePath;
    //more code
}

PS.
The first argument would be the path to your exe file BTW, and the second argument is the "%1" command which is used to instruct the program to open the file -not print it for example-. The Thrid argument -i.e. args[2]- I bilieve is what you are looking for. Try to show them one by one in MessageBoxs ro see the value of each before deciding which to pass to the Form's constructor.

Problem with reading INI Files, and a listview question.

Well, I've found several INI Readers here, which helped, but they didn't solve my real problem.
My INI file I have (which I cannot change, I only read from it), has stuff like this:

[Section]<br />
Key=Value<br />
Key=Value2<br />
Key=Value3<br />
Key=Value4<br />
Key=Value5

etc... Same key, but 5 different values. Every INI Reader I've seen so far, will only read the first one.
Does anyone have any solution?

Secondly, In my dialog I have this listview, which I want to fill from a self-made method. The listview is simply called "listView1", but whenever I try to use that name in my method (i.e. listView1.Items.Add("Test");) I get this error:
An object reference is required for the nonstatic field, method, or property 'WindowsApplication1.Form1.listView1'
What do I need to do to make it work :p

(1) You have done you own version of INI file, so you have to make a reader for that...

(2) I don't know (maybe posting the code will help).

(1) No, I haven't. As I specific earlier, the INI file is made by an external program (a game, to be specific).

(2) What code? the INI Reader I found?

(1) OK, my hypothesys was wrong, you didn't write that. Anyway, IMHO, you have to write a reader for such non-compliant INI file.

(2) That was referring to the listview trouble you experienced.

(2) errr.. I deleted it because I couldn't get it, but I used something like this (well it had more, but this suffices to prodouce the same error):

public static void LoadFavorites()<br />
{<br />
  listView1.Add.Items("test");<br />
}

(1) The Windows API GetPrivateProfileSection loads a buffer will all section content (keys are NULL separated). I don't know if it will be of any help to you.
(2) Ok, let's forget about it...

A) The only built-in way I know of to read an INI file is with the Windows API and P/Invoke:

        <br />
[System.Runtime.InteropServices.DllImport ( "kernel32" , SetLastError=true , EntryPoint="GetPrivateProfileString" )]<br />
        private unsafe static extern uint<br />
        API_GetPrivateProfileString<br />
        (<br />
            string lpAppName        <br />
        ,<br />
            string lpKeyName        <br />
        ,<br />
            string lpDefault        <br />
        ,<br />
            byte*  lpReturnedString <br />
        ,<br />
            int    nSize            <br />
        ,<br />
            string lpFileName<br />
        ) ;<br />
<br />
        public unsafe static int<br />
        GetPrivateProfileString<br />
        (<br />
            string     lpAppName        <br />
        ,<br />
            string     lpKeyName        <br />
        ,<br />
            string     lpDefault        <br />
        ,<br />
            out string lpReturnedString <br />
        ,<br />
            int        nSize            <br />
        ,<br />
            string     lpFileName<br />
        )<br />
        {<br />
            int    result ;<br />
            byte[] temp   = new byte [ nSize ] ;<br />
<br />
            fixed ( byte* ptemp = temp )<br />
            {<br />
                result = (int) API_GetPrivateProfileString<br />
                (<br />
                    lpAppName        <br />
                ,<br />
                    lpKeyName        <br />
                ,<br />
                    lpDefault        <br />
                ,<br />
                    ptemp            <br />
                ,<br />
                    nSize            <br />
                ,<br />
                    lpFileName<br />
                ) ;<br />
            }<br />
<br />
            lpReturnedString = PIEBALD.Lib.LibStr.FromByteArray ( temp , true ).Substring ( 0 , result ) ;<br />
<br />
            return ( result ) ;<br />
        }<br />

B) You need to provide a reference to an instance to listView1.Items.Add(), the literal "Test" won't work.

Yeah I managed to fix no 2.

As for the first one, that still doesn't help...
What I need is something that can read INI Files using:
FileName, Secion Name, Key Name, and N.
N being the Nth matching key...
Any ideas?

If you don't have time to do it right, when will you have time to do it over?

Or consider putting each in its own file?
