Binary junk

[XerxesTheMighty]

How would I create a variable with a binary value or Hex value? For instance, '00 00 00 00', has no ascii equivalent.

An easy way is to allocate an automatic variable and 'forgetting' to initialize it. It can contain anything.
This is a typical error.

If you want to be creative, fill the variable with 'binary junk' (I like that expression).

{
char junk[32]; // Don't know what's in it

junk[0] = 0x01;
junk[1] = 0x05;
etc.... you are in charge .....
}

That won't help me much with what I'm doing. That's ingenious though. See, I'm making a REG_BINARY key. The problem is that it's inputing characters and not binary data (so therefore screws the registry key up).

PS: And if you liked my 'binary junk', you should see the programs I write.

No, that is not a problem. Characters are nothing but mappings in a certain character set, in otherwords, 8-bit binary values.

Besides, the buffer is typecasted to the LPVOID type anyway.

Found the solution (this will work with REG_BINARY or REG_DWORD)::

RECT j = {0,0,0,0};//fill this with data

RegSetValueEx(key, "Name of key", 0, REG_BINARY,(CONST BYTE*)&j.left, sizeof(j.left));
