I have a rich text box that is being updated with log information. There is a button to save the log output to a file. When I use the code below to try to save the output to a file, I receive "The process can't access the file because it is being used by another process" exception. I am not sure why I am receiving this exception. It happens on new files that I create in the dialog. It happens on any file I try to save the information to.
private void saveLog_Click(object sender, EventArgs e)
{
OnFileDialogOpen(this, new EventArgs());
// Displays a SaveFileDialog so the user can save the Image
// assigned to Button2.
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "Text File|*.txt|Log File|*.log";
saveFileDialog1.Title = "Save Log File";
saveFileDialog1.ShowDialog();
// If the file name is not an empty string open it for saving.
if (saveFileDialog1.FileName != "")
{
// Saves the Image via a FileStream created by the OpenFile method.
System.IO.FileStream fs =
(System.IO.FileStream)saveFileDialog1.OpenFile();
// Saves the Image in the appropriate ImageFormat based upon the
// File type selected in the dialog box.
// NOTE that the FilterIndex property is one-based.
switch (saveFileDialog1.FilterIndex)
{
case 1:
try
{
this.logWindow.SaveFile(saveFileDialog1.FileName, RichTextBoxStreamType.PlainText);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
break;
case 2:
try
{
this.logWindow.SaveFile(saveFileDialog1.FileName, RichTextBoxStreamType.PlainText);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
break;
}
fs.Close();
OnFileDialogClose(this, new EventArgs());
}
}
It seems the same file is opened twice. First you create it using:
System.IO.FileStream fs =
(System.IO.FileStream)saveFileDialog1.OpenFile();
Then you pass the same file name to this.logWindow.SaveFile
, which presumably opens the file with the given name and saves data to it.
I guess the first call is unnecessary.
