append a registry string from batch

I have a particular registry string that I want to first check if it exists, if not create it and give it a value or if it does exist, append info to the end of the string that is already there.  How can this be done?

Probably you have to use some programs from NT resource kit
regdmp.exe, regini.exe. Get the key with the regdmp.exe
into  file  

regdmp.exe \\hkey_local_machine\..... > the_file.txt

check the required key with simple perl or kixtart script
and put/append required value to the file

and then run

regini.exe program which will put the key into the registry

Sorry,  I would like to do this without any special software on the end user machine.

There are no tools on a standard machne to do this.
You either need to write a program to do this, or use a tool from somewhere, NT reskit, WSH,  VB, or a good installation program.

I hope this helps !

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Basically you just want it to be there. Whether it was there or not, you want it to be there in the end, as i understand your question.

So i suggest that you create that specific key/value on you own computer, and export the key to a reg file. Then you can just run the reg file with the command
start <name of regfile>

If you do want the info, whether it was there or no, had a value etc..., i agree with Sysexpert. You need an external program. To add to the list that Sysexpert has given you i can also suggest kix, which also should be able to do this.

Hope this helps

can you not use kixTart its great for adding registry keys
just copy it to the Netlogon directory along with all the dlls a you then got yourself a great scripting language that will do all you ever wanted

I have to agree.  What I did was create a way of doing it in VB and made an EXE and then added it to my install script.  This seems to work fine.  Thanks for all the help.

I created a wsf file to back up, find, append and/or create the necessary registry settings.  In my case, I wanted to append the value to the PATH, so that it would be permanent instead of temporarily changing the path in a command window.  I made it so that I could re-run the wsf as necessary.

I left in some of the comments (I ran into a problem with creating a wscript.object, so I went to wmi).  Also if you want to see what type of items are in the registry, I left that code in too.  Enjoy.
