Is it possible to create/have a non-modal .net OpenFileDialog I have a UI element in the main dialog which always need to be available for the user to press.
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
No, OpenFileDialog and SaveFileDialog are both derived from FileDialog, which is inherently modal, so (as far as I know) there's no way of creating a non-modal version of either of them.
You can create a thread and have the thread host the OpenFileDialog. Example code is lacking any kind of synchronization but it works.
public partial class Form1 : Form
{
OFDThread ofdThread;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ofdThread = new OFDThread();
ofdThread.Show();
}
}
public class OFDThread
{
private Thread t;
private DialogResult result;
public OFDThread()
{
t = new Thread(new ParameterizedThreadStart(ShowOFD));
t.SetApartmentState(ApartmentState.STA);
}
public DialogResult DialogResult { get { return this.result; } }
public void Show()
{
t.Start(this);
}
private void ShowOFD(object o)
{
OpenFileDialog ofd = new OpenFileDialog();
result = ofd.ShowDialog();
}
}
With this code you could add something to fire an event in your UI thread (be careful with invoking!) to know when they're done. You can access the result of the dialog by
DialogResult a = ofdThread.DialogResult
from your UI thread.
