Hi

Lets say you have a form (frmTest) that needs to remember the value of a text field (tbTest) when it is closed, so that it can retrieve that value and fill the form in again (presuming the data isn't stored within a table..)

' This saves the contents of the field 'tbText' into a registry entry called 'ValueInTextBoxWeNeed'
Private Sub Form_Close()
    SaveSetting "MyExampleDB", "frmTest", "ValueInTextBoxWeNeed", Me.tbText
End Sub

' This retrieves the registry entry called 'ValueInTextBoxWeNeed' and places its value into the control 'tbText', note the double quotes at the end of GetSetting, this is the default setting that should be used if the registry does not contain an entry called 'ValueInTextBoxWeNeed'
Private Sub Form_Load()
    Me.tbText = GetSetting("MyExampleDB", "frmTest", "ValueInTextBoxWeNeed", "")
End Sub

Regards

Nick

The syntax should be something like:

SaveSetting "YourApplicationName","Settings","LastShutdown",now()

The First parameter describes your application name.
The second the general nature/group of the information you're going to save.
The third parameter describes specifically the peice of information that is going to be saved
The final parameter is the value of the information to be saved.

Thus the above example will store the LastShutdown time of your application, inside the Settings group.
It will create the following key in your registry.
HKEY_CURRENT_USER\Software\VB and VBA Program Settings\YourApplicationName\Settings\LastShutDown  = "28/10/03 09:37:40"

This information can then be read back using the GetSetting function

Dim strDate as String
Dim dtmDate As Date

strDate = GetSetting("YourApplicationName","Settings","LastShutdown")
'strDate now holds "28/10/03 09:37:40"
'Not GetSetting always returns a string value

dtmDate=CDate(strDate) 'Convert the string date back to a real date.


The GetSetting function also has a fourth parameter call Default. If this is specified then the value in Default is used if an entry in the registry cannot be found.
ie.
strDate = GetSetting("YourApplicationName","Settings","LastStartUp",now())

Note we are looking for the LastStartUp value, as we haven't created this registry entry yet (using SaveSetting) it will return the current Date and Time.
