RegWrite Question

Recommended Posts

I am attempting to read in a reg value, append some data to that value and the write it back to the same key. The data I'm reading is contains Env. Variables such as %systemdrive%. When I read it into a variable, autoit converts it to the literal or C:\. I can work around this by doing a string replace, but when I do a RegWrite, I get C:\ back into the registry. Any ideas how to get Rewrite to write %systemdrive% instead of C:\?

I have tried using Opt(ExpandEnvStrings, 1/0) to no avail. Any help would be appreciated!

why first convert it and then change it back to %systemdrive% ?

maybe you can explain what you want to accomplish and post what you have ?

I'm not trying to convert it actually. RegRead and RegWrite are converting it for me... Anyway I'm trying to read in the "Path" info, which contains Env. Variables, specifically, %systemdrive%. I want to write back to the registry what I read out, not C:\.

Thanks.

I just tried and I don't have this problem.

Script I tested:

RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey", "REG_SZ", "%windir%")

$a = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey")
RegDelete("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey")

MsgBox(0,'',$a)

What OS are you using?

Funny, does this show %systemdrive% or c:\

I get %systemdrive% returned

RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey", "REG_SZ", "%systemdrive%")

$var = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey")
MsgBox(1,"",$var)

I must be retarded then. I have XP Pro SP1 installed on this packaging machine. Not sure what the deal is. The only thing I see here is that you are creating the key, and I'm overwriting one that is already created. They key type is a bit different too, yours being REG_SZ, mine being REG_EXPAND_SZ. Test it with that key type and let me know.

Thanks.

No difference:

RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey", "REG_EXPAND_SZ", "DoomedKey")
RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey", "REG_EXPAND_SZ", "%windir%");So it overwrites.

$a = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey")
RegDelete("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey")

MsgBox(0,'',$a)

cmacrun can you try OURS script?

(mine will delete the key so you wont leave a trace...)

No change. What about on yours?

RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey1", "REG_EXPAND_SZ", "%systemdrive%")

$var = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKey1")
MsgBox(1,"",$var)

test your code first by displaying what was read, and rigth before you put it back. I am thinking your script is converting it when you process it.

Ok, on win2k, I found a few env variables. Works fine here with this code.

I read what is there, and overwrite it, and then read it again.

$var = RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", "Recent")
MsgBox(1,"Test1",$var)
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", "Recent", "REG_EXPAND_SZ", $var)
$var2 = RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", "Recent")
MsgBox(1,"Test2",$var2)

Just to make sure, I changed it to test and wrote the original back.

$var = RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", "Recent")
MsgBox(1,"Test1",$var)
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", "Recent", "REG_EXPAND_SZ", $var & "1")
$var2 = RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", "Recent")
MsgBox(1,"Test2",$var2)
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders", "Recent", "REG_EXPAND_SZ", $var)

Ok this is strange, when I look at the actual registry value, it shows %systemdrive%, but when I go through system properties, it shows C:\. This was not happening prior to running the script, so it must be something with the way the OS is processing the key after being modified. Go figure. Thanks for the prompt responses on this. Sorry for the false alarm!
