Registry Key Contains Comma - How To Escape It?

[XShayanX]

As you can see in the following picture, all these Registry keys contain comma,
How can I escape them?
I'm using RegRead and RegWrite.


I have searched and found this:
https://autohotkey.com/board/topic/96759-run-a-filename-that-contains-a-comma/
But I'm scared to try it. I don't wanna mess up my Registry xD

Thanks very much!

That post you linked is correct. Check out EscapeChar to see how an accent is used for certain characters.

But RegWrite isn't working.. although I'm running AHK with UAC access:

Code: Select all

072: RegWrite,REG_BINARY,HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\{d0649ed1-77fc-4bd5-a5f6-cf5600c5136f}\Properties,{24dbb0fc-9311-4b3d-9cf0-18ff155639d4},1,%Listen1Ch
073: }
077: Return (60.08)

Here's my actual code:

Code: Select all

x::
regread,Listen1,HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\{d0649ed1-77fc-4bd5-a5f6-cf5600c5136f}\Properties,{24dbb0fc-9311-4b3d-9cf0-18ff155639d4}`,1
Listen1State := SubStr(Listen1, 17, 4)
Listen1First := SubStr(Listen1, 1, 16)
Listen1Last := SubStr(Listen1, 21)
If (Listen1State = "ffff") {
	Listen1Change := Listen1First . "0000" . Listen1Last
	Listen1Length := StrLen(Listen1)
	Listen1ChangeLength := StrLen(Listen1Change)
	If (Listen1Length != Listen1ChangeLength) {
		MsgBox, "Lengths don't match."
		return
	}
	RegWrite,REG_BINARY,HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\{d0649ed1-77fc-4bd5-a5f6-cf5600c5136f}\Properties,{24dbb0fc-9311-4b3d-9cf0-18ff155639d4}`,1,%Listen1Change%
}
Else If (Listen1State = "0000") {
	Listen1Change := Listen1First . "ffff" . Listen1Last
	Listen1Length := StrLen(Listen1)
	Listen1ChangeLength := StrLen(Listen1Change)
	If (Listen1Length != Listen1ChangeLength) {
		MsgBox, "Lengths don't match."
		return
	}
	RegWrite,REG_BINARY,HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\{d0649ed1-77fc-4bd5-a5f6-cf5600c5136f}\Properties,{24dbb0fc-9311-4b3d-9cf0-18ff155639d4}`,1,%Listen1Change%
}
Else {
	MsgBox, "What is cheese?! `n(idk what happened xd)"
}
return

Wait is it possible to write a variable to a registry value?

Code: Select all

RegWrite,REG_BINARY,HKLM,SOFTWARE\...\Properties,{24dbb0fc-9311-4b3d-9cf0-18ff155639d4}`,1,%Listen1Change%

Refer to this:
https://www.autohotkey.com/docs/commands/RegWrite.htm
RegWrite, ValueType, KeyName , ValueName, Value
Here is what you're doing
ValueType = REG_BINARY
Keyname = HKLM
ValueName = SOFTWARE\...\Properties
Value = {24dbb0fc-9311-4b3d-9cf0-18ff155639d4}`,1
Which means your variable isn't assigned to anything.


It looks like there is an extra comma between HKLM and the path. Try replacing it with a \ like so:

Code: Select all

RegWrite,REG_BINARY,HKLM\SOFTWARE\...\Properties,{24dbb0fc-9311-4b3d-9cf0-18ff155639d4}`,1,%Listen1Change%

Edit: Looks like you did the same thing with RegRead.

[XShayanX]

I was using the old syntax: RegWrite, ValueType, RootKey, SubKey , ValueName, Value
Regardless, I used the new syntax as you suggested but to no avail.
I check the registry value, and it still does not change after I press my hotkey.
At this point I'm really doubting regwrite supports %variables%

Try adding msgbox %Listen1Change% prior to the RegWrite and see if it's a valid value.
Another test is to create a test variable with a static value that you know is correct and insert that in RegWrite

[XShayanX]

All values are correct

Code: Select all

Listen1[24 of 63]: 0B0000000100000000000000
Listen1Change[24 of 63]: 0B00000001000000ffff0000
Listen1ChangeLength[2 of 3]: 24
Listen1First[16 of 63]: 0B00000001000000
Listen1Last[4 of 7]: 0000
Listen1Length[2 of 3]: 24
Listen1State[4 of 7]: 0000

Okay, what if you copy the output from the msgbox and paste it as the value for the last parameter in RegWrite and RegRead? If that works, then I would imagine you would be correct about it variables being problematic in the function.

[XShayanX]

Good thinking!
I tried what you said, it didn't write it to registry...
I wonder what's wrong..

[XShayanX]

Sounds like there's bug with RegWrite in writing to HKLM:
https://www.autohotkey.com/boards/viewtopic.php?f=76&t=62582
I don't know what to do now...
I have tried running the script with UAC access, as admin, converted it to exe and ran it as admin but all to no avail.

[just me]

I don't think there's a bug. IMO, you need (at least) admin rights to write to the key. You might want to try the following:

Code: Select all

#NoEnv
RegKey := "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture\{d0649ed1-77fc-4bd5-a5f6-cf5600c5136f}\Properties"
RegVal := "{24dbb0fc-9311-4b3d-9cf0-18ff155639d4},1"
RegRead, Listen1, %RegKey%, %RegVal%
If (ErrorLevel) {
   MsgBox, 16, Error!, Error when trying to read the registry: %A_LastError%
   ExitApp
}
RegWrite, REG_BINARY, %RegKey%, %RegVal%, %Listen1%
If (ErrorLevel) {
   MsgBox, 16, Error!, Error when trying to write the registry: %A_LastError%
   ExitApp
}
MsgBox, 0, Success, All right!
ExitApp

[XShayanX]

Thanks so much for the code.
I remember after I ran the hotkey, I double clicked on script icon on the status bar and from "Variables and their contents" I checked ErrorLevel, it was 0 but after I tried your code, I found out that ErrorCode is 5 (something must have interfered that my ErrorLevel was 0), and from Microsoft's Doc: https://docs.microsoft.com/en-us/windows/win32/debug/system-error-codes--0-499-
ERROR_ACCESS_DENIED
5 (0x5)
Access is denied.
As I said, I tried running the script normally, as admin and with UI Access even before this, but I did again, and I get ErrorLevel 5 for all of them:
I even tried converting the script to exe and then run it as admin, but no.. it still didn't work.

What if you open up regedit and go to the value and try to change it there? That could narrow down if it's a permission issue with the account/the value is locked, or with ahk making the edit.

Here is something that could help:
https://www.howtogeek.com/262464/how-to-gain-full-permissions-to-edit-protected-registry-keys/

[XShayanX]

I have already tried that, I can modify and rename the values and keys without an issue with RegEdit, and I can export and apply *.reg files no problem.

BTW, I have a couple of other hotkeys in my script which use RegWrite to write to HKCU and HKU, and they work without an issue

Just right now I also prepended this script of mine with this:

Code: Select all

if not A_IsAdmin
Run *RunAs "%A_ScriptFullPath%"

Which makes sure my script is running as Admin.
