CeRegOpenKeyEx fails with -2147467256

[Guest]

Does any one have trouble with CeRegOpenKeyEx
I get an error : -2147467259 and I can't figure out what it is
I am using the following code

result = CeRegOpenKeyEx(HKEY_LOCAL_MACHINE, L"SOFTWARE\\Microsoft\\.NETCompactFramework", 0, 0, &hKey)

char msg[1024]
LPVOID lpMsgBuf;
if( FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM, NULL, result, 0, (LPTSTR) &lpMsgBuf, 0, NULL) == 0

sprintf(msg, "%s ", (LPCSTR)lpMsgBuf);
MessageBox( NULL, msg, "Error Message", MB_OK )
// Free the buffer.
LocalFree( lpMsgBuf );


result comes back as -2147467259, and the only string I am able to get back from FormatMessage is "PE" ... :

Any ideas what I should be looking at
All other RAPI seem to work fine.

Wow I foudn out that this might be a timing issue
I found out through testing that if I put a MessageBox(...) call prior to the CeRegOpenKeyEx() call, things work fine. Then I tried putting a Sleep(3000) instead of a MessageBox and it works as well
Is this possible
Could it be that the RAPI initialization needs some more time to completely initialize

Thank

Absolutely if you're connecting asnchronously.

No no, in this case everything is synchronous.
