Hi Afrow UK,

Even simple script

LockedList::AddFile /NOUNLOAD $SYSDIR\kernel32.dll"
LockedList:ialog

doesn't work for me.

I get messages "Going to compile test program and then run it"
then "The file '$TEMP\nsz1325.tmp\Lock' is now locked. It will appear on the LockedList dialog page soon..." some dialog blinks and that's all.

The same result I've got with example provided with plugin.

[Afrow UK]

Firstly, you're missing a quote and secondly that's a module not a file.

How about this script:

code:
Name "LockedList Test"

OutFile "LockedListTest.exe"



!include MUI.nsh



!insertmacro MUI_PAGE_WELCOME

Page Custom LockedListShow



!insertmacro MUI_LANGUAGE English



Function LockedListShow

  LockedList::AddModule /NOUNLOAD "$SYSDIR\kernel32.dll"

  LockedList:ialog

FunctionEnd



Section

SectionEnd

You'll get some garbage for the first program captions. I might be able to fix this.

Thank you for sample but it also doen't work for me.
It seems that the problem is exactly in LockedList:ialog

I modified your sample adding three message boxes

code:


Name "LockedList Test"

OutFile "LockedListTest.exe"



!include MUI.nsh



!insertmacro MUI_PAGE_WELCOME

Page Custom LockedListShow



!insertmacro MUI_LANGUAGE English



Function LockedListShow

  MessageBox MB_OK "test1"

  LockedList::AddModule /NOUNLOAD "$SYSDIR\kernel32.dll"

  MessageBox MB_OK "test2"

  LockedList:ialog

FunctionEnd



Section

 MessageBox MB_OK "test3"

SectionEnd

and I can see only two of them.

[Afrow UK]

You're not going to see the 3rd one because the dialog stops execution of the installer until it is closed.
What exactly happens? Does the dialog not display?

Edit: Also, what OS are you on?

Stu

[daisywheel]

dialog doesn't appear. installer is closed after message box "test2" closed.

OS: WinXP SP2

[Afrow UK]

That's interesting. I'm running Win XP SP2 also.

What happens if you don't use any AddFile/AddModules.

Stu

[daisywheel]

ok, sorry for delay with answer. I had to deal with something.
now I'm sure that the problem is in LockedList:ialog

I have two vesions of script

code:


Name "LockedList Test"

OutFile "LockedListTest.exe"



!include MUI.nsh



!insertmacro MUI_PAGE_WELCOME



!insertmacro MUI_PAGE_INSTFILES



Page Custom LockedListShow



!insertmacro MUI_LANGUAGE English



Function LockedListShow

  MessageBox MB_OK "test1"

  LockedList::AddModule /NOUNLOAD "$SYSDIR\kernel32.dll"

  MessageBox MB_OK "test2"

  LockedList:ialog

FunctionEnd





Section "Install"

 MessageBox MB_OK "test3"

SectionEnd

and

code:


Name "LockedList Test"

OutFile "LockedListTest.exe"



!include MUI.nsh



!insertmacro MUI_PAGE_WELCOME



Page Custom LockedListShow



!insertmacro MUI_PAGE_INSTFILES





!insertmacro MUI_LANGUAGE English



Function LockedListShow

  MessageBox MB_OK "test1"

  LockedList::AddModule /NOUNLOAD "$SYSDIR\kernel32.dll"

  MessageBox MB_OK "test2"

  LockedList:ialog

FunctionEnd





Section "Install"

 MessageBox MB_OK "test3"

SectionEnd

the first one shows message boxes
"test3"
"test1"
"test2"

the second one
"test1"
"test2"

diff:
!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_INSTFILES
Page Custom LockedListShow

!insertmacro MUI_PAGE_WELCOME
Page Custom LockedListShow
!insertmacro MUI_PAGE_INSTFILES

we contact directly so I can help you debug plugin

[Afrow UK]

Located the problem thanks to daisywheel
Please be patient while we make sure everything is ok then I shall upload the updated version.

Stu

[Afrow UK]

Uploaded v0.2 RC2.

http://nsis.sf.net/File:LockedList.zip

Stu

[daisywheel]

LockedList::AddModule /NOUNLOAD "$SYSDIR\module.dll"
LockedList::AddModule /NOUNLOAD "$SYSDIR\kernel32.dll"

in case file module.dll doesn't exist will result error in functionality - there will no dependencies found

in case we change order
LockedList::AddModule /NOUNLOAD "$SYSDIR\kernel32.dll"
LockedList::AddModule /NOUNLOAD "$SYSDIR\module.dll"

plugin will work in another manner. I don't think this is expected behaviour.

[Afrow UK]

Found the problem. It was a bad array pointer. It wasn't the fact of the file not being there it was simply only taking the first file or module added with AddFile/AddModule.

I was also able to fix the captions problem. I noticed captions were being repeated over multiple processes aside from the garbage caption for the first few processes. Just needed a ZeroMemory in there.

Uploaded v0.2 RC3.

One more suggestion. I'm not compeltely happy with results.
For example, I have two browser application run: Internet Explorer and Moxilla Firefox both on page http://nsis.sourceforge.net/File:LockedList.zip

also I use following code in a script

code:


LockedList::AddModule /NOUNLOAD "$SYSDIR\kernel32.dll"

LockedList:ialog

and as results I've got
WINAMP.COM | Forums - LockedList plug-in - Moxilla Firefox (firefox.exe)
for Moxilla Firefox
and
AutoSuggest Drop-Down (iexplore.exe)
for IE
