How to read value from the registry C++?

[EDN Admin]

Hi All,
This is the code Im writing to read from my Windows 7 registry using VS2008.
Im able to read the value, but only the 1st character.But not the whole string.I think there is a problem with "char buf[255] = {0};" but not sure.
Can any one please help??
Note : the value in registry is "AT/AT COMPATIBLE"; Im only able to read "A".
Thanks in advance.

{<br/>

char buf[255] = {0};<br/>
DWORD dwType = 0;<br/>
//DWORD BufferSize = TOTALBYTES;<br/>
// PPERF_DATA_BLOCK PerfData = (PPERF_DATA_BLOCK) malloc( BufferSize );<br/>
