Q: Example for Registry solution problem
Hello,

we're linux experts and we don't know registy :(
This is our problem:
With a format already used by other programs (e.g. .jpg or .pdf) we want to add
a new
WriteRegStr HKCR "TXTFile\shell\compile\command"
to the existing ones

Please can you send us an .nsi example (probably is not a bad idea to add it
also to NSIS examples.

Thanks

NSIS Examples
The makensis.nsi script has a section "NSI Development Shell Extensions" which might be helpful. It should have been installed if you chose a Full install or selected the example files that comes with NSIS.

Re: NSIS Examples
Thanks,

this is exactly the example we studied.
The problem is that this example use Write and rewrite the precedent configuration. We'd like to add a new command to the existing commands.

Hi sanface,

I am guessing you want to add the 'Compile' command to the right-click menu of a TXT file.

The simplest way of doing this is:

  WriteRegStr HKCR TXTFile\Shell\Compile\Command '' `"$INSTDIR\Your Program.exe" "%1"`

where '$INSTDIR\Your Program.exe' is your program, and '"%1"' is the TXT file, sent to your program as a parameter surrounded by double quotes.

But because you can't be absolutely sure of the key, you should check the extension to see where it points:

  ReadRegStr $0 HKCR .TXT ''
  WriteRegStr HKCR $0\Shell\Compile\Command '' `"$INSTDIR\Your Program.exe" "%1"`

If you like, you can reply with the actual extension, the name that should appear on the right-click menu, and the program that should run, and I'll write the piece of script for you, that will take care of the association.

Petersa,

Thanks you've understood our problem:
following your notes we've tried to use
ReadRegStr $0 HKCR .PDF ''
WriteRegStr HKCR $0 Shell\Compile\Command '' '"$INSTDIR\pdfcrypt.exe" -input "%1" -output "crypt.pdf"'

It seems not work (we're using 1.7b) :(

Can you suggest us also the uninstall part?

Thanks a lot

Hi Fabrizio,

use

WriteRegStr HKCR $0\Shell\Compile\Command '' '"$INSTDIR\pdfcrypt.exe" -input "%1" -output "crypt.pdf"'

instead of

WriteRegStr HKCR $0 Shell\Compile\Command '' '"$INSTDIR\pdfcrypt.exe" -input "%1" -output "crypt.pdf"'

(you have a typo between $0 and Shell).

To delete this Registry Key you could use

ReadRegStr $0 HKCR .PDF ''
DeleteRegKey HKCR $0\Shell\Compile

Hope it helps -
