Registry Configuration Functions

Brief History: I have written this Class in the distant 20 August 1997 and since then not the never more modified (power of the Objects Programming!). I am based on the example code of a Visual Basic 5 Handbook .

Members :

Name	Declaration	Description
CreateStructure	Sub CreateStructure(hKey As Long, SubKey As String)	Add a Key.
DeleteStructure	Sub DeleteStructure(hKey As Long, SubKey As String)	Delete a Key.
DeleteValue	Sub DeleteValue(hKey As Long, SubKey As String, ValueName As String)	Delete a Value.
ReadValue	Function ReadValue(hKey As Long, SubKey As String, ValueName As String, [Default As String]) As String	Read a Data for a Value and a Key.
WriteValue	Sub WriteValue(hKey As Long, SubKey As String, ValueName As String, vNewValue As String)	Set the Data in the Value of a Key. If not exist the Key or the Value then they will be created.

Where :

Parameter Name	Description
hKey	General Key of the Registry. ex. HKEY_LOCAL_MACHINE = &H80000002
SubKey	Application Key. ex. "\SOFTWARE\GiulioSPA\N3DPro\ImageSaver"
ValueName	Value Name for the current Key. ex. "JPGDetail"
Default	Default Value for the not available case. ex. "85"
vNewValue	Data for the current Value. ex. "75"

Example of use :

Const HKEY_LOCAL_MACHINE = &H80000002

Private m_JPGDetail as Long

Private m_REGKEY as String

Private m_RegSvr as New RegFun

m_REGKEY = "\SOFTWARE\GiulioSPA\N3DPro\ImageSaver"

To read the JPG Detail :

m_JPGDetail = m_RegSvr.ReadValue(HKEY_LOCAL_MACHINE, m_REGKEY, "JPGDetail", 15)

To insert the JPG Detail :

Call m_RegSvr.WriteValue(HKEY_LOCAL_MACHINE, m_REGKEY, "JPGDetail", m_JPGDetail)

To delete the "JPGDetail" Value from the value list of the key m_REGKEY :

Call m_RegSvr.DeleteValue(HKEY_LOCAL_MACHINE, m_REGKEY, "JPGDetail")

To Add a subKey of the current:

Call m_RegSvr.CreateStructure(HKEY_LOCAL_MACHINE, m_REGKEY & "\Dummy")

To delete the previous Key :

Sub m_RegSvr.DeleteStructure(HKEY_LOCAL_MACHINE, m_REGKEY & "\Dummy")

Part of the code here above written is used in the JPG Save. See the N3DCommon section.
