Hiya folks, I'm having difficulties reading registry keys for a
program I'm writing.  What I'm doing is loading filenames into
variables, in this case all the filenames are .wav's

// Open Registry
RegOpenKeyEx(HKEY_LOCAL_MACHINE, "SOFTWAREOGCANTradeHelper", 0,
KEY_QUERY_VALUE, &hKey);

// Get the string and store it in CamDir
if (RegQueryValueEx(hKey, "CamelotDirectory", NULL, NULL, (LPBYTE)
CamDir, &dwBufLen)){
    // Display error on fail.
    MessageBox( NULL, "CamDir", "TradeHelper v1.5", MB_OK );
}
// When reading multiple keys I just copy and paste the above
// code and change the relevant bits... I'm not closing between each
read.

// Close Registry
RegCloseKey(hKey);

Ok, this works fine, BUT when I try to get all 23 of the values I
need, it fails on some... For example it failed on the 8th, 18th and
20th keys...  So I shuffle things around, move 4 keys to the end of
the list... and then it fails on the 4th, 14th, 17th, and 20th.
Depending how I move things, I can get all keys to succeed or fail,
but can't figure out WHY this is happening...

I've fought with this for a whil enow and can't figure out whats going
on... any help would be much appreciated :)

Someone replied to my query on Usenet... Thought I'd share it here.  Apparently My noobness got the best of me, time to rework the way I handle this!
