Registry question

[Jonny123]

i'm trying to store value in a binary key on the left portion where hex values are written.

I'm able to store values in the binary key through REG_BINARY but it stores the value on the right portion where ASCII values are written.

I tried REG_SZ but that changed the key to string value.

How can I store the value on the left portion in binary key?

In order to set a binary value, pass the RegSetValueEx API the bytes that represent the string you want to store. Example:

Dim hKey As Long
Dim arrString(2) As Byte
  
arrString(0) = 65
arrString(1) = 68
arrString(2) = 69
    
RegOpenKeyEx hKeyEY_LOCAL_MACHINE, "", ByVal 0&, ByVal 0&, hKey
RegSetValueEx hKey, "Blah", 0, REG_BINARY, arrString(0), Len(arrString(0)) * (UBound(arrString) + 1)
RegCloseKey hKey

That will create a new value under HKEY_LOCAL MACHINE, named "Blah". TIt will hold the string "ADE"
