C# Windows not opening on top

Question

Relates to my previous question.

In my previous question I asked why my dialogs seem to be opening behind other windows. (Other windows not necessarily belonging to my program, e.g. Excel, Windows Explorer, etc.)

I was told to use the overloaded ShowDialog() and pass the parent as a parameter.

That's fine, and I've replaced all the ShowDialog()s with the overload.

However I still had the same problem here:

static class Program
{
  /// <summary>
  /// The main entry point for the application.
  /// </summary>
  [STAThread]
  static void Main()
  {
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);

    OpenFileDialog ofd = new OpenFileDialog();
    ofd.ShowDialog(); // First dialog

    // Do some stuff here...

    SaveFileDialog sfd = new SaveFileDialog();
    sfd.ShowDialog(); // Second dialog;
  }
}

In this example (don't comment on the code - I just wrote it up as a simple example), the user double-clicks the executable with several windows on their screen. The OFD appears on top, and the SFD appears underneath everything.

I usually have this sort of OFD/SFD set up in my simple programs which accept CSV or XLS files and do some simple processing of them. In this case, I put the OFD code in the static Main() method and load the dialog if no parameters were passed to the exe.

Answer 1

There is an other - I think the easiest - solution:

        ofd.ShowDialog(new Form() { TopMost=true });

It opens a new form, that will be immediately disposed, but it will give TopMost property to your ofd. You can give more properties like "TopLevel":

        ofd.ShowDialog(new Form() { TopMost=true, TopLevel=true });

        threadFolderBrowserDialog.Start();
        Console.WriteLine("Запуск выбора папки и файла в новом потоке");

        bool Exit = false;
        while (!Exit)
        {
            var exit = Console.ReadLine() == "exit" ? Exit = true : Exit = false;
            Console.WriteLine("Выход из программы по команде exit");
        }
    }
    [STAThread]
    static void voidFolderBrowserDialog()
    {
        FolderBrowserDialog fbd = new FolderBrowserDialog();
        if (fbd.ShowDialog(new Form() { TopMost = true, WindowState = FormWindowState.Minimized }) == DialogResult.OK)
        {
            Console.WriteLine(fbd.SelectedPath);
        }
        OpenFileDialog ofd = new OpenFileDialog();
        if (ofd.ShowDialog(new Form() { TopMost = true, WindowState = FormWindowState.Minimized }) == DialogResult.OK)
        {
            Console.WriteLine(ofd.FileName);
        }
    }
