NSIS - custom dialog and dll functions

Hi,

I never used NSIS installer and the thing I need is not so simple (at least I think).

After starting a setup and after clicking Next on the welcome screen I need a custom dialog with edit (password) field to appear. User would input password into the field and on clicking next I would verify the password by calling my dll function (dll would be inside setup). If my dll function returns true user may continue Next.

I know how to do this by using INNO setup but would like to transfer all my setups to NSIS.

So, I hope you will be able to help me since there is a lot of stuff here

1) Creating a custom page
2) Calling a dll function

Thank you!

1. nsDialogs plug-in
2. System plug-in

See the Examples folder.

OK. I created a dialog and it all works fine. The next thing I need to do is to extract my dll into temporary folder and connect to it. As I saw it, I should be using $PLUGINSDIR to address the temporary folder?

The problem is that the following code has no effect, since I'm probably doing something wrong:

Section
InitPluginsDir
SetOutPath $PLUGINSDIR
File mydll.dll
SectionEnd

I need mydll.dll to be extracted at the beginning of the setup or just before my custom dialog appears.


EDIT: Found something.

Function .onGUIInit
InitPluginsDir
File /oname=$PLUGINSDIR\mydll.dll "mydll.dll"
FunctionEnd

This works..
