Hi guys,

After getting an 'undeliverable' error when sending my question to Ralph Ludwig (developer of XREG3.DLL), I decided to post it here in order to get some info. I'm wondering if you can help me with this one...

Purpose of the tool I wrote is to read the content of HKLM\Software\Microsoft\CurrentVersion,DevicePath, check if a specified path is in this string and then add or delete it.

This certain registry type is STRING_EXPAND_SZ, so it can't be read by VDS3.5 (which was why I use XREG3.DLL instead).

Now, I've found that the information that is returned from the registry read operation sometimes is altered, mainly when multiple signs like '%' or ';' are used.

Example:
If my registry contains: %systemroot%;%systemroot%\inf

...and I use this code to read the value:
XREG read
%%RegContent = @XREG(HLM,SOFTWARE\Microsoft\Windows\CurrentVersion,DevicePath)

...%%RegContent contains: %systemroot%;%systemroot%\infy (notice the y at the end).

If I would write this registry key back to the registry, it would contain incorrect information.

Did anyone of you see this problem or has a solution for it? Is there an alternative to XREG3.DLL, which can also read and write to REG_EXPAND_SZ registry types (or can do more operations in the registry)?

Thanks for your help.

If there is some regularity in the error eg.
It always puts a y at end for a given string and z at begining for some other then you can check for these characters using @substr function and deleting off the extraneous character however if it's random then .. I don't know. May be some one has a better idea.

Hi,

The character is not always added, and it's not always a y. It can be other characters aswell. So if I don't know the content of the registry key (which is the case in 99%), I can't predict or test if a certain character was added or not.

Regards,
JayDee

Did you try Tommys vdsdll.dll (version 3) . belive it registry read and write commands and functions. That work with vds3 & vds 4

Hi Nathan,

Yes, this was the one I was looking for. I didn't realize that these registry functions were included in VDSDLL Smile

Thanks for the help!
