ReadRegStr and user variables
I'm trying to do the following:

ReadRegStr $2 HKLM $R4 $R7

It doesn't work, but if replace R4 and R7 with their values, then it does. I've double-checked for typos, and haven't found any. What am I doing wrong?

Thanks!

maybe you need to quote variables.

Should Work
The following worked for me using NSIS 2.0b under Windows 98 SE.


;--------------------------
# [Global Pseudo-constants]
;--------------------------
  !Define TrialName       "ReadRegTest"

;------------------
# [.exe Attributes]
;------------------

  Name "${TrialName}"
  OutFile "${TrialName}.exe"
  Caption ""
  Subcaption 3 ": Trial"
  ShowInstDetails show

;------
Section
;------
  StrCpy $R4 ".MP3"
  StrCpy $R7 "Content Type"
  ReadRegStr $2 HKCR $R4 $R7
  DetailPrint $2
SectionEnd ; ================================

Output in the listbox is: audio/mid
NOTE: It worked OK even without enclosing $R7 in quotes.
Are you getting a compile error or just no output?
Are you sure the ValueName you're trying to read exists in the registry?

I finally found out my problem: there was a newline at the end of one of the vars! I thought the messagebox I used to debug automatically made a new line because of space constraints, not because it was in one of the vars! Oh well, live and learn :)
