控件名 属性 值
Label1 Caption 注册表键值：
Label2 Caption 注册姓名：
Label3 Caption 空
Label4 Caption 注册公司：
Label5 Caption 空
Label6 Caption 空
Text1 Text 空
Text2 Text 空
Command1 Caption 写入注册表
Command2 Caption 退出
然后，在
程序的声明部分添加如下代码：
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA"
(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 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
Const error_success = 0&
Const error_baddb = 1009&
Const error_badkey = 1010&
Const error_cantopen = 1011&
Const error_cantread = 1012&
Const error_cantwrite = 1013&
Const error_registry_recovered = 1014&
Const error_registry_corrupt = 1015&
Const error_registry_io_failed = 1016&
Const hkey_classes_root = &H80000000
Const hkey_current_user = &H80000001
Const hkey_local_machine = &H80000002
Const REG_SZ = 1
Const regkey = "software\My Soft\My program"
接着为各个控件添加代码，代码如下：
Private Sub Command1_Click()
Dim keyvalue As String
Dim retvalue As Long
Dim keyid As Long
retvalue = RegCreateKey(hkey_local_machine, regkey, keyid)
keyvalue = Text1.Text
retvalue = RegSetValueEx(keyid, "注册名", 0&, REG_SZ, ByVal keyvalue,
Len(keyvalue) + 1)
keyvalue = Text2.Text
retvalue = RegSetValueEx(keyid, "注册公司", 0&, REG_SZ, ByVal keyvalue,
Len(keyvalue) + 1)
If Text1.Text $#@60;$#@62; "" And Text2. t $#@60;$#@62; "" Then
Label3.Caption = Text1.Text
Label5.Caption = Text2.Text
End If
End Sub
Private Sub Command2_Click()
Unload Me
End
End Sub
Private Sub Form_Load()
Dim retvalue As Long
Dim result As Long
Dim keyid As Long
Dim keyvalue As String
Dim subkey As String
Dim bufsize As Long
Label6.Caption = regkey
retvalue = RegCreateKey(hkey_local_machine, regkey, keyid)
If retvalue = 0 Then
subkey = "注册名"
retvalue = RegQueryValueEx(keyid, subkey, 0&, REG_SZ, 0&, bufsize)
If bufsize $#@60; 2 Then
keyvalue = ""
retvalue = RegSetValueEx(keyid, subkey, 0&, REG_SZ, ByVal keyvalue, Len(keyvalue)
+ 1)
Else
keyvalue = String(bufsize + 1, " ")
retvalue = RegQueryValueEx(keyid, subkey, 0&, REG_SZ, ByVal keyvalue, bufsize)
keyvalue = Left$(keyvalue, bufsize - 1)
Text1.Text = keyvalue
End If
Label3.Caption = keyvalue
subkey = "注册公司"
retvalue = RegQueryValueEx(keyid, subkey, 0&, REG_SZ, 0&, bufsize)
If bufsize $#@60; 2 Then
keyvalue = ""
retvalue = RegSetValueEx(keyid, subkey, 0&, REG_SZ, ByVal keyvalue, Len(keyvalue)
+ 1)
Else
keyvalue = String(bufsize + 1, " ")
retvalue = RegQueryValueEx(keyid, subkey, 0&, REG_SZ, ByVal keyvalue, bufsize)
keyvalue = Left$(keyvalue, bufsize - 1)
Text2.Text = keyvalue
End If
Label5.Caption = keyvalue
End If
End Sub
好了，存盘，按F5运行程序，在两个Text中分别写入你的“注册姓名”和“注册公司”的名称，然后单击“写入注册表”按钮，现在打开“注册表编辑器”，找到HKEY_LOCAL_MACHINE\SOFTWARE\My
Soft\My Program，看看右边是不是生成了“注册名”和“注册公司”两个键值，是的话，恭喜你，你成功了。
