MessageBox is not displayed (focused) after SaveFileDialog

Question

For some reason, after my SaveFileDialog, my application will never show a MessageBox. Is there something I'm missing? Or is this a problem with threads?

I run the application as a Windows Form application using VS 2010 Express.

I have no exceptions.

To add: When I look at the code, everything seems to be going well. Which is strange, so I think this is a problem of time.

Indicated by LarsTech and others, MessageBoxes do appear, however the focus is gone; in other words, the MessageBox is being squeezed out of other windows or minimized. This is problem.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Globalization; using System.IO; namespace SpeedDating { class Program { [STAThread] static void Main(string[] args) { string filename = "test.test"; // args[0]; string ext = filename.Substring(filename.LastIndexOf('.')); SaveFileDialog dialog = new SaveFileDialog(); dialog.Title = "SpeedDating App"; dialog.RestoreDirectory = true; dialog.CheckFileExists = false; dialog.CheckPathExists = false; dialog.FileName = DateTime.Now.ToString("yyyyMMdd") + ext; DialogResult result = dialog.ShowDialog(); if (result == DialogResult.OK && dialog.FileName != "") { try { FileStream outfs = File.Create(dialog.FileName); FileStream infs = File.Open(filename, FileMode.Open); infs.CopyTo(outfs); infs.Close(); outfs.Close(); } catch (NotSupportedException ex) { MessageBox.Show("Probably removed the original file."); } } else { MessageBox.Show("No path found to write to."); } MessageBox.Show("I came here and all I got was this louzy printline"); } } } 

Answer 1

I tried this, and he immediately showed:

  MessageBox.Show(new Form() { WindowState = FormWindowState.Maximized, TopMost = true }, "You clicked Cancel button", "Cancel"); 

Answer 2

Try this for your message box.

 MessageBox.Show(this,"Probably removed the original file."); 

Answer 3

I created a new project and pasted your code, and it works for me. Before starting, make sure that you have completed a complete rebuild. Also with this line:

 dialog.FileName = DateTime.Now.ToString(format) + "." + ext; 

A dialog box will display the file name. Therefore, only pressing the cancel button (provided that you do not clear the save dialog at the beginning) will bring up a message box. Anyway, I got a message box that popped up if you didn't pass the IF test anyway. Your code looks good.

Perhaps you should put SaveFileDialog in use to ensure that it is removed before the MessageBox is called:

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using System.Globalization; using System.IO; namespace SpeedDating { class Program { [STAThread] static void Main(string[] args) { string filename = "test.test"; // args[0]; string ext = filename.Substring(filename.LastIndexOf('.')); using (SaveFileDialog dialog = new SaveFileDialog()) { dialog.Title = "SpeedDating App by K.Toet"; dialog.RestoreDirectory = true; dialog.CheckFileExists = false; dialog.CheckPathExists = false; dialog.FileName = DateTime.Now.ToString("yyyyMMdd") + ext; DialogResult result = dialog.ShowDialog(); if (result == DialogResult.OK && dialog.FileName != "") { try { FileStream outfs = File.Create(dialog.FileName); FileStream infs = File.Open(filename, FileMode.Open); infs.CopyTo(outfs); infs.Close(); outfs.Close(); } catch (NotSupportedException ex) { MessageBox.Show("Probably removed the original file."); } } else { MessageBox.Show("No path found to write to."); } } MessageBox.Show("I came here and all I got was this louzy printline"); } } }
