Hi all,

Brand new to AHK, but not new to coding. I installed AHK to play with and already have run into an issue.

I'm just trying to read the value of a reg key, and it's coming back empty (I've confirmed there's in fact, a value in the actual registry key itself). I copied & pasted the exact RegRead code straight from the help file, changing only the key.

Here's the entire code in my file so far:

Code: Select all

#NoEnv
#Warn
SendMode Input
SetWorkingDir %A_ScriptDir%

RegRead, OutputVar, HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\VirtualBox, InstallDir
MsgBox, Program files are in: %OutputVar%

then when I run it using SciTE4AutoHK (or even directly via a command prompt, the messagebox just shows no value returned?

Running this on Windows 10 x64. Any ideas? Thought this lang was supposed to be almost n00b-proof?

There is a small difference:

Code: Select all

RegRead, OutputVar, HKEY_LOCAL_MACHINE, SOFTWARE\Microsoft\Windows\CurrentVersion, ProgramFilesDir
RegRead, OutputVar, HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\VirtualBox, InstallDir

See the comma after HKEY_LOCAL_MACHINE?

Hi Rindis,

RootKey\SubKey [v1.1.21+]

If RootKey is followed immediately by a slash (\), RootKey and SubKey are merged into a single parameter.

If the key and value exist I would have thought that your script would work.

Try this in SciTE4AutoHotkey and/or as a separate script:

Code: Select all

q:: ;test RegRead
RegRead, vFontName, HKEY_CURRENT_USER\Software\Microsoft\Notepad, lfFaceName
MsgBox, % vFontName
RegRead, vFontName, HKEY_CURRENT_USER, Software\Microsoft\Notepad, lfFaceName
MsgBox, % vFontName
return

Note also: what version of AutoHotkey are you using, in case it's a version before v.1.1.21.

[EDIT:] Cheers qwerty12, I had meant to mention about SetRegView. While trying to explain/present things carefully, things can slip your mind.

Hi,

I don't have VirtualBox installed to test, but if your AutoHotkey is 32-bit and you're working with a 64-bit VirtualBox, you probably need to add SetRegView 64 before doing the RegRead.

EDIT:
~~(Or maybe SetRegView 32 if you're using a 64-bit AutoHotkey and VirtualBox is 32-bit)~~ - err, not going to happen - VirtualBox relies on kernel drivers...

J Scott Elblein: You're welcome
