I get in my log file for ex., Processing detected chassis type: {1}

Which means $R2 == "{1}"

But it is not processing the logic for that variable... I am not sure if it is returning some type of ascii that is not making it truly = to {1}. I do see in the WMI.nsh file they are stripping CRLF's...

1

This is the next like, I am not sure 110% what it is doing, but almost looks like it is adding back in a new line..

"$\n" "$1" 

Any Help would be appreciated...

Thanks,

Put it in a MessageBox surrounded by some extra characters to be sure there are no new lines in the string.

Good call afrow, I was trying to do a char to ascii earlier after trimming the { } off of it... my output looks like it has a tab in it...

"R2 = before$R2after" 

R2 = before{1}        after 

>

Looks like I have a trim out a tab somehow.. Ill take ideas but should have a solution when you next read this...

Thanks,

Since I am only worried about parsing the digits out, I just did this filter and it dumped everything else...

    ${StrFilter} $R2 "1" "" "" $R2

Thanks again,
