ReadEnvStr
  Hello out there,

I'm just starting with this fine install system, but i ran into a little problem.

for a certain application i need to get an environment variable, the help came up with this function:

4.9.2.9 ReadEnvStr
user_var(output) name
Reads from the environment string "name" and sets the value into the user variable $x. If there is an error reading the string, the user variable is set to empty, and the error flag is set.

But i can't get it to work properly, can somebody help me using this function??

Tnx in advance

grtz

Hi !

Here is a little example, I hope it helps :)

Name "Example1"

>OutFile "example1.exe"


>Section ""

 ReadEnvStr $0 "COMSPEC"

 ReadEnvStr $1 "USERNAME"

 ReadEnvStr $2 "HOMEDRIVE"

 ReadEnvStr $3 "HOMEPATH"

 ReadEnvStr $4 "ALLUSERSPROFILE"

 ReadEnvStr $5 "LOGONSERVER"

 

>MessageBox MB_OK "COMSPEC: $0 $\r$\n USERNAME: $1 $\r$\n HOMEDRIVE: $2 $\r$\n HOMEPATH: $3 $\r$\n ALLUSERSPROFILE: $4 $\r$\n LOGONSERVER: $5"

>SectionEnd
