Remove Spaces from string with Installscript
I am trying to remove spaces from a string using InstallScript. I try to use the StrReplace(svString," ","") which kinda works, but I have some strings that could have (" " )unknown number of spaces in the strings.
I was also looking from something that works like TRIM,LTRIM,RTRIM.

I haven't used them, but there seem to be some other approaches at www.installsite.org > InstallScript Samples > Strings.

StrReplace(svFileLines,"\t","",0);
StrReplace(svFileLines," "," ",0);
\\ optional if the first two do not remove all empty space from a string.
CharReplace(svFileLines,STRTOCHAR('\0'),STRTOCHAR(''),0);
