Question

I am using VS 2008 (C#)… I have created a function in a GlobalClass to use it globally.. This is for opening a dialog box. When I call this function in my method it works but I am not able to use the Object “OFD” that I have created here…

static class GlobalClass
{
 public static void OFDbutton()
  {
   OpenFileDialog ofd = new OpenFileDialog();
   ofd.Filter = "Image files|*.jpg;*.jpeg;*.png;*.gif";
   DialogResult dr = ofd.ShowDialog();
  }
}

In the form method. I am using

globalclass.ofdbutton(); //Calling the function
lable1.text=ofd.filename;

I want to use object “ofd” but I am unable to do so.. What I have to do about this, please help

Answer 1

I guess what you want is

static class GlobalClass
{
 public static OpenFileDialog OFDbutton()
  {
   OpenFileDialog ofd = new OpenFileDialog();
   ofd.Filter = "Image files|*.jpg;*.jpeg;*.png;*.gif";
   DialogResult dr = ofd.ShowDialog();
   return ofd;
  }
}

which gives back the OpenFileDialog object. Now you can

OpenFileDialog ofd = globalclass.ofdbutton(); //Calling the function
label1.text=ofd.filename;
