RegEnumValue API--can't get consistent behavior

[LiquidSchwarz]

I am trying to get registry values using RegEnumValue API. I am not getting consistent results.

Private Declare Function RegEnumValue Lib "advapi32.dll" Alias "RegEnumValueA" ( _
ByVal hKey As Long, _
ByVal dwIndex As Long, _
ByVal lpValueName As String, _
lpcbValueName As Long, _
ByVal lpReserved As Long, _
lpType As Long, _
lpData As Any, _
lpcbData As Long) _
As Long


The example I found at AllAPI.net does not seem to work properly. It seems to skip values even though there is nonzero data in those values.

When enumerating values for a test key, I am getting fatal errors if I use anything but a null value for the argument lpData.

I would include more code, but I have tried so many things I don't know where to begin.

TIA

Check out this MSDN discussion of the API call

Note particularly the description of the dwIndex and the lpData fields.

The answer.....

Use RegOpenEx instead of RegOpen.

No more crashes.
