求助。vb.net 部分api不成功的原因？
刚开始接触vb.net。
发现很多vb6能直接使用的api放在vb.net中调用失败了。
比如说 在vb6环境里以下方法可以使用，但是在vb.net中返回值不正确。
Private Declare Function RegOpenKeyEx Lib "advapi32.dll" _
Alias "RegOpenKeyExA" ( _
ByVal hKey As Long, ByVal lpSubKey As String, ByVal ulOptions As Long, _
ByVal samDesired As Long, phkResult As Long _
) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" ( _
ByVal hKey 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 Any _
) As Long
上面这些是用来对注册表进行操作的，现在找到vb.net中也封装了一些能对注册表进行读取的方法。
2楼还会贴出找不到替代方法的api。求各位大神指教。 API VB.NET
[解决办法]
imports System.Runtime.InteropServices 看看

VB.NET中API声明有些不同，如Long类型要改成Integer等：
Declare Function RegOpenKeyEx Lib "advapi32.dll" Alias "RegOpenKeyExA" (ByVal hKey As Integer, ByVal lpSubKey As String, ByVal ulOptions As Integer, ByVal samDesired As Integer, ByRef phkResult As Integer) As Integer
可以搜下看看
