Saving to registry..........

I need to save some very simple things in my program to the registry. Can someone post a short example of how to Read and write to the windows registry? Also, are there any differences with this in Windows XP? All I need to save is whether or not a a checkbox is checked or not. Then when I load the program get the registery setting and set the checkbox value to that. To be honest, I don't need to save settings much in the small apps I make, and I have forgotten how to do this!:) I had a module of how to use Get & Save setting in one of my programs, but it was lost when I cleaned up my system and upgraded to Win XP. Any example appreciated.

SaveSetting and GetSetting are the most commonly used. They are limited in scope, however. Here is an example of reading a registry key using a copy of the Registry APIs. For more examples, down load the free API Viewer from http://www.allapi.net

VB Code:

Private Const HKEY_CURRENT_USER = &H80000001
Private Const HKEY_LOCAL_MACHINE = &H80000002
 
Private Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Private Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, lpData As Any, lpcbData As Long) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
 
Private Sub Command1_Click()
Dim Result As Long
Dim KeyRet As Long
Dim KeyToRead As String
Dim KeyValue As String
Dim Length As Long
Result = RegOpenKey(HKEY_CURRENT_USER, "Software\KPD-Team\APIViewer 2001\", KeyRet)
KeyToRead = "MSDN"
Result = RegQueryValueEx(KeyRet, KeyToRead, 0, 0, "", Length)
KeyValue = Space$(Length - 1)
Result = RegQueryValueEx(KeyRet, KeyToRead, 0, 0, ByVal KeyValue, Length)
MsgBox KeyValue
RegCloseKey KeyRet
End Sub

Hack could u tell me if i can use your code to put read/write option to my vb6 application. could u explain to me where i can get the module for it. Api viewer dowload section has many thigns to downlod . which one do i need? thanks

without API:

VB Code:

'save to registry
    'chkAutoCapsLock is a checkbox and im saving its value in the reg
    'u can put this in a command button click event
    SaveSetting "mySchool", "Settings", "AutoCaps", chkAutoCapsLock

to get the value and assign to checkbox:

VB Code:

Sub GetSettings()
On Error GoTo HELL
 
    chkAutoCapsLock = CInt(GetSetting("mySchool", "Settings", "AutoCaps", "0"))
 
    GoTo CleanUp
HELL:
    WriteError Err.Number, Err.Description, Date, Me.Name, "GetSettings"
CleanUp:
End Sub
