Question

so I made a program that creates a registry key on the pc, that adds an option to push your file to your device. (The program itself pushes files to your Android sd card.)

Everything works well, or at least should, once I figure out this issue. When I right-click on an item and choose my command (which is to open up with my program) my program just opens up, but no arguments are passed.

A month ago, I designed a program that opens when the user double clicks (just double click, not right-clicking through context menu) a file, it opened the specific program, and from there I was able to grab the arguments.

Why can’t I from the context menu?

Thanks, sorry for lengthy post.

And here’s part of my code:

private void Form1_Load(object sender, EventArgs e)
    {
        string c = textBox3.Text;

          string[] args = System.Environment.GetCommandLineArgs();

          try
          {

              string location = args[1];
              MessageBox.Show(location);
              //For testing purposes only

              Properties.Settings.Default.thinglocation = location;
              Properties.Settings.Default.Save();
              Process();
          }

          catch
          {

          }

Here’s the registry code. BTw string c is “C:\File push.exe” the location of my program.

 string MenuName = "*\\shell\\NewMenuOption";
                string Command = "*\\shell\\NewMenuOption\\command";

                RegistryKey regmenu = null;
                RegistryKey regcmd = null;
                try
                {
                    regmenu = Registry.ClassesRoot.CreateSubKey(MenuName);
                    if (regmenu != null)
                        regmenu.SetValue("", "Push to Android");
                    regcmd = Registry.ClassesRoot.CreateSubKey(Command);
                    if (regcmd != null)
                        regcmd.SetValue("", c +"%1");
                }
                catch (Exception ex)
                {
                    MessageBox.Show(this, ex.ToString());
                }
                finally
                {
                    if (regmenu != null)
                        regmenu.Close();
                    if (regcmd != null)
                        regcmd.Close();

I assume that you have created a registry entry which creates the context menu item which you are using to launch your program. Likelihood is that you need to add ‘ %1’ after the name of the exe you want to launch. In the context menu registry entries %1 represents the selected file, so adding this should launch your program and provide the name of the selected file as the single argument.

the reason why it worked before with the double click is that windows will launch the default program for the file double clicked, with the double clicked file as the argument.
