C # Properties.Settings.Default Doesn't work as expected
I was working on a program to automate backup checks using LogMeIn backup (a window based program). Now I need a way to store user preferences so that information can be stored easily. I've never worked with app / user preferences that are somewhat "built in" and decided to give it a try, but ran into problems.
I added four settings: IncludeCriteria (Specialized.StringCollection) ExcludeCriteria (Specialized.StringCollection) ReportPath (string) ReportType (int)
But the behavior is not acting as expected (go figure). After saving some values in my program, I will go back to editing / viewing my settings values using the VS 2008 settings editor. None of my values are saved. While I think it might be because these values are only default values, wouldn't that be where they can be saved / read / changed?
Here is my upload form code (still very unrefined):
private void setupForm()
{
txtPath.Text = BackupReport.Properties.Settings.Default.ReportPath == null ? "" : BackupReport.Properties.Settings.Default.ReportPath;
if (BackupReport.Properties.Settings.Default.ReportType == 0)
{
radioHTML.Checked = true;
}
else
radioExcel.Checked = true;
if (BackupReport.Properties.Settings.Default.IncludeCriteria.Count > 0)
{
listIncludeCriteria.DataSource = Properties.Settings.Default.IncludeCriteria;
//foreach (string s in Properties.Settings.Default.IncludeCriteria)
// listIncludeCriteria.Items.Add(s);
}
if (BackupReport.Properties.Settings.Default.ExcludeCriteria.Count > 0)
{
listExcludeCriteria.DataSource = BackupReport.Properties.Settings.Default.ExcludeCriteria;
//foreach (string s in Properties.Settings.Default.ExcludeCriteria)
// listExcludeCriteria.Items.Add(s);
}
}
listIncludeCriteria is just a list. When the user saves, I call this method:
private void saveSettings()
{
//var settings = BackupReport.Properties.Settings;
if (txtPath.Text != "")
{
BackupReport.Properties.Settings.Default.ReportPath = txtPath.Text;
}
if (listIncludeCriteria.Items.Count > 0)
{
//BackupReport.Properties.Settings.Default.IncludeCriteria = (StringCollection)listIncludeCriteria.Items.AsQueryable();
foreach (var i in listIncludeCriteria.Items)
{
if (!isIncludeDuplicate(i.ToString()))
BackupReport.Properties.Settings.Default.IncludeCriteria.Add(i.ToString());
}
}
if (listExcludeCriteria.Items.Count > 0)
{
//BackupReport.Properties.Settings.Default.ExcludeCriteria = (StringCollection)listExcludeCriteria.Items.AsQueryable();
foreach (var i in listExcludeCriteria.Items)
{
if (!isExcludeDuplicate(i.ToString()))
Properties.Settings.Default.ExcludeCriteria.Add(i.ToString());
}
}
if (radioExcel.Checked == true)
BackupReport.Properties.Settings.Default.ReportType = 1;
else
BackupReport.Properties.Settings.Default.ReportType = 0;
BackupReport.Properties.Settings.Default.Save();
//Properties.Settings.Default.Save();
this.DialogResult = DialogResult.OK;
this.Close();
}
It looks like when the form loads, the path I put in the first time seems to show up (ReportPath) - even the listBoxes fill up a bunch of crap that I put in, but I can't find those values anywhere.
Any help would be appreciated!

You should save after editing / adding
Settings.Default.Save();
Simple example I use a lot
private void Main_Load(object sender, EventArgs e)
{
this.Location = Settings.Default.WindowLocation;
}
private void Main_FormClosing(object sender, FormClosingEventArgs e)
{
Settings.Default.WindowLocation = this.Location;
Settings.Default.Save();
}
