Example
The following C# example of a handler for a button's Click event creates an instance of the JournalReader class and uses it to read an existing Journal file.
Note
The DisplayXml method called from this example is not shown. The specific implementation of such a method is dependent on your application's needs.
private void btnLoad_Click(object sender, System.EventArgs e)
{
Stream jntStream;
Stream xmlStream;
Microsoft.Ink.JournalReader jntReader = new Microsoft.Ink.JournalReader();
OpenFileDialog openFileDialog1 = new OpenFileDialog();
// Get the filename from the user by using a File Open dialog
openFileDialog1.InitialDirectory = "c:\\";
openFileDialog1.Filter =
"Journal files (*.jnt)|*.jnt|All files (*.*)|*.*";
openFileDialog1.FilterIndex = 1;
openFileDialog1.RestoreDirectory = true;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
try
{
if ((jntStream = openFileDialog1.OpenFile()) != null)
{
// Read in the Journal file
xmlStream = jntReader.ReadFromStream(jntStream);
// Display results
DisplayXml(xmlStream);
}
}
catch (System.Exception ex)
{
Debug.WriteLine(ex.Message);
}
finally
{
// Clean up
xmlStream.Close();
jntStream.Close();
}
}
}
