using the registary

can someone please tell me how to add something to the registary. Please dont put links to tutorials and stuff, what I need is a simple code that will save text.text to the registary, it contains 1 character.
please help

thanks in advance

To save a retrieve values from the Registry:

Code:

---

Public Const HKEY_CLASSES_ROOT = &H80000000
Public Const HKEY_CURRENT_USER = &H80000001
Public Const HKEY_LOCAL_MACHINE = &H80000002
Public Const HKEY_USERS = &H80000003
Public Const HKEY_PERFORMANCE_DATA = &H80000004

Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hkey As Long) As Long
Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hkey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hkey As Long, ByVal lpSubKey As String) As Long
Declare Function RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal hkey As Long, ByVal lpValueName As String) As Long
Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hkey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
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
Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hkey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData As Any, ByVal cbData As Long) As Long

Function RegQueryStringValue(ByVal hkey As Long, ByVal strValueName As String)
   
    Dim lResult As Long
    Dim lValueType As Long
    Dim strBuf As String
    Dim lDataBufSize As Long
   
    On Error GoTo 0
    lResult = RegQueryValueEx(hkey, strValueName, 0&, lValueType, ByVal 0&, lDataBufSize)
    If lResult = ERROR_SUCCESS Then
        If lValueType = REG_SZ Then
            strBuf = String(lDataBufSize, " ")
            lResult = RegQueryValueEx(hkey, strValueName, 0&, 0&, ByVal strBuf, lDataBufSize)
            If lResult = ERROR_SUCCESS Then
                RegQueryStringValue = StripTerminator(strBuf)
            End If
        End If
    End If
   
End Function

Public Function GetString(hkey As Long, strpath As String, strvalue As String)

    Dim keyhand&
    Dim datatype&
    r = RegOpenKey(hkey, strpath, keyhand&)
    GetString = RegQueryStringValue(keyhand&, strvalue)
    r = RegCloseKey(keyhand&)

End Function

Function StripTerminator(ByVal strString As String) As String
    Dim intZeroPos As Integer

    intZeroPos = InStr(strString, Chr$(0))
    If intZeroPos > 0 Then
        StripTerminator = Left$(strString, intZeroPos - 1)
    Else
        StripTerminator = strString
    End If
End Function

Public Sub savestring(hkey As Long, strpath As String, strvalue As String, strdata As String)

    Dim keyhand&
    r = RegCreateKey(hkey, strpath, keyhand&)
    r = RegSetValueEx(keyhand&, strvalue, 0, REG_SZ, ByVal strdata, Len(strdata))
    r = RegCloseKey(keyhand&)

End Sub

Usage
Use the Functions GetString and SaveString to retrieve and save values to the Registry. Here is an example. Make a Form with 2 CommandButtons's and put the following code into them.

Code:

---

Private Sub Command1_Click()

    'Save a Value to the Registry
    savestring HKEY_CURRENT_USER, "Software\Myapp", "Testing", "Hello"
   
End Sub

Private Sub Command2_Click()

    'Get a value from the Registry
    Retval = GetString(HKEY_CURRENT_USER, "Software\Myapp", "Testing")
    Print Retval

End Sub

Thanks alot Megatron!!!! I have 1 more question, before when I had it in txt files, I use encryption, is it still nessesary? or not any more? Or do you suggest to use encryption?

this is what I have for the command buttons:

Code:

---

Private Sub Command1_Click()

    'Save a Value to the Registry
    savestring HKEY_CURRENT_USER, "Software\Pc Protecter", Text1.Text
   
End Sub

Private Sub Command2_Click()

    'Get a value from the Registry
    Retval = GetString(HKEY_CURRENT_USER, "Software\Pc Protecter")
    Print Retval

End Sub

---

now, how do I get what ever I put in text1.text to appear in text2.text (from the registary)

Try this.

Code:

---

Text2.Text = GetString(HKEY_CURRENT_USER, "Software\Pc Protecter")

---

it doesn't work I get an error message:

Code:

---


Private Sub Command1_Click()

    'Save a Value to the Registry
'**********************************
'error: argument no optional
    savestring HKEY_CURRENT_USER, "Software\Pc Protecter", Text1.Text
'**********************************
   
End Sub
________________________________________________
Private Sub Command2_Click()

    'Get a value from the Registry
 '  Retval = GetString(HKEY_CURRENT_USER, "Software\Pc Protecter")
  '  Print Retval

Text2.Text = GetString(HKEY_CURRENT_USER, "Software\Pc Protecter")

End Sub

---

That's because you are missing the last argument. If you do not want to use it, just pass a blank string

Code:

---

savestring HKEY_CURRENT_USER, "Software\Pc Protecter", Text1.Text, "" 'If you want, you can also pass vbNullString

---

no erros come up but it still doesn't work

can you do me a favor, make a simple program that has 2 text boxes and 2 command boxes, and the registary code, and email me the source. my email is [email protected], if its too much work then forget about it, oh and please post if you can or can not.

I looked at the above code and saw that you have not included your blank string, make sure to include it.

Code:

---

savestring HKEY_CURRENT_USER, "Software\Pc Protecter", Text1.Text, ""

---

Code:

---

Text2.Text = GetString(HKEY_CURRENT_USER, "Software\Pc Protecter", "YourValueHere")

---

I just realized that maybe it's confusion. When you enter the path, you do not include the value. The value has it's own argument (the 3rd one).

Also, I just sent you the example.

Kalong.RegWrite "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Winlogon\LegalNoticeText", "0000000000000"

Did you mean to respond to a thread that was 7 years old? In any case if you want a simple way to use the Registry take a look at the How to use SaveSetting and GetSetting link in my signature.
