strcmp problem
I'm trying to read a certain line from a text file to see if it needs replacing or not. Here's the code I'm using:

Push 1484
Push "$TEMP\923.txt"read
Call ReadFileLine
Pop $0
StrCmp $0 "                                        <png layoutpos=bottom contentalign=bottomright flip=false idres=100 alpha=40 padding=rect(0,0,18,0)/>" dontreplace replace

The problem is that even though the 2 strings are equal, it still goes to the replace label instead of the dontreplace. Where did I go wrong ?

Try:

Push 1484
Push "$TEMP\923.txt"
 Call ReadFileLine
Pop $0
Push $0
 Call TrimNewLines
Pop $R0
StrCmp $0 "                                        <png layoutpos=bottom contentalign=bottomright flip=false idres=100 alpha=40 padding=rect(0,0,18,0)/>" dontreplace replace

You need the TrimNewLines function (from NSIS docs / archive)

Nope. It still goes to the replace label each time.

I figured it out. You probably ment:
StrCmp $R0 ...

It works that way. Thanks !

Oh yes, you are correct. Actually...

Pop $0
StrCmp $0 ...

...would be better (re-use same variable)
