I still after reading several articles to save user prefernces am very lost.

These are the settings I need to save.

Image.Checkbox
Desc.Checkbox

Windows Program size

Heres the doozy:

I have a search form, as the user enter the field to search for.  If they choose to they can save that text to thier favorites.
Then I will have them click a favorite button(favbtn) that will display there saved strings.  When selected it will fill the txtbox for a search.

I just have a problem witht the saving of the favorites.  I would prefer and Ini file as it seems easier to use, or xml, but I would like to stay away from the registry.

Thanks for all the help, This site ROCKS.

malanois, you are right  - XML seems to be reasonable solution. I would suggest the following schema:
<USERS>
  <USER username="john">
    <IMAGE></IMAGE>
    <DESCR></DESCR>
  </USER>
  <USER username="anny">
    <IMAGE></IMAGE>
    <DESCR></DESCR>
  </USER>
</USERS>

Samples for reading and writing XML:

It does not really matters whether it's WinForms or WebForms. Could you publish your source code here, I'll try to figure out what you did wrong.

I think
1- You have to add a Typed Dataset to your project. (From the solution explorer, Add a new item, DataSet)
2- Add a Table to it to define all the data you need to store. (Add an ELEMENT from the toolbox to your dataset, name it, then add your fields with data types)
3- Anytime you need to save some data, use the following code: (I assume, you name your dataset as DATASET1)
   Dim ds As New Dataset1
   Dim r As New Dataset1.Table1Row=ds.Table1.NewRow
   r.[Preference1]=[Value1]
   r.[Preference2]=[Value2]
   ...
   ds.Table1.Rows.Add(r)
   ds.WriteXML([FilePath])

4- Anytime you need to load the data, write the following code:
   Dim ds As New Dataset1
   ds.ReadXML([FilePath])
   [Value1]=ds.Table1.Rows([INDEX YOU NEED]).[Preference1]
   ....
