It should be this:

bResult = CryptEncrypt(
hKey, // Key obtained earlier
0, // No hashing of data
FALSE, // Final or only buffer of data
0, // Must be zero
sSrcData, // No data this time
&dwSize, // length of the source data
0 // Size of block
);

> /* THIS DOESN'T WORK.
> 1. Does not update dwSize value
> 2. Affects (screws up) encrypted data
> 3. Am I using it the wrong way?????
