Replace a placeholder in a file

[congahonga]

Hi there,

I have three files, that must be filled with values that i get during installation process, because the user must input these values in textfields.

How can I replace a placeholder (e.g $XXXX) with a NSIS variable in(!) a config-file ?


-----------------------------
# config File

blabla=1230

aValue=$XXXX (this must be repaced)

link=http://$XXXX/test/test.dll
