RegEnumValue problems.
-
I wrote my code in VB(It is hell but i had not choice), but it does not work. I keeps returning error 234 (ERROR_MORE_DATA). But i have a 12 Kb buffer, which means the problems is something else. Please Help. I am already 3 hours in this &^&%&%.:mad::mad::mad:

ERROR_MORE_DATA is not really an error. It simply means that there are more values to enumerate. RegEnumValue does not enumerate *all* values, you give it a counter, and it enumerates one at a time. For instance (yes, this is C++ code, but you can figure out the algorithm):
DWORD error; DWORD index = 0; TCHAR nameBuff[1024]; TCHAR valueBuff[1024]; DWORD nameBuffSize, valueBuffSize; DWORD type; do { nameBuffSize = valueBuffSize = 1024; error = ::RegEnumValue(hSectionKey, index, nameBuff, nameBuffSize, 0, &type,(BYTE *)valueBuff, &valueBuffSize); if(error == ERROR_SUCCESS || error == ERROR_MORE_DATA) { // do something with the enumerated value } index++; } while(error == ERROR_SUCCESS || ERROR == ERROR_MORE_DATA);

Sometimes I feel like I'm a USB printer in a parallel universe.I think i found it. Stupid vb does not understand NULLS.

error = ::RegEnumValue(hSectionKey, index, nameBuff, nameBuffSize, 0, NULL,NULL,NULL);Does not work with VB (&^%$^^&^%&) :mad:. Thank you all. I changed my code and it works now.
