NSIS help

I would wait until your leave page function to query the state of all the checkboxes. That way you can do it in one function, no need to query each time you change the check mark (I'm assuming this is a multi-launcher).

So your pages would be

Page custom nsDialogsPage nsDialogsPageLeave ; 

Then in your leave page func
Function nsDialogsPageLeave
   SendMessage $Firefox ${BM_GETSTATE} 0 0 $0
   ${If} $0 != 0
	StrCpy $Firefox "true"
   ${Else}
	StrCpy $Firefox "false"
   ${EndIf}

   SendMessage $Thunderbird ${BM_GETSTATE} 0 0 $2
   ${If} $2 != 0
	StrCpy $Thunderbird "true"
   ${Else}
	StrCpy $Thunderbird "false"
   ${EndIf}

   etc...
FunctionEnd

Then in your main page you can drop all the nsdialogs::OnClick and GetFunctionAddress lines.
PS - NSD has a builtin macro for OnClick, ie
${NSD_OnClick} $Firefox OnCheckboxFirefox

Here's the AutoIt3 source and sample INI file. I run this launcher from a separate NSIS launcher which, among other things, mounts my TrueCrypt volume and sets some temporary environment variables. That's where the EnvGet("PADrive") comes from in the run section.

And the INI -

# relative path to root of mounted volume

[launch]
PStart=PortableApps\PStart\PStart.exe
CAFE=PortableApps\CAFE\cafe.exe
VirtualBox=PortableApps\VirtualBoxPortable\VBStart.bat
MojoPac=Start.exe

to include

!include "WinMessages.nsh"

Sorry, I told ya I hadn't used that code in a while

Ok, so I'm also a little drunk right now, and I can't for the life of me find Simeon's launcher source to try my code that I posted here and above to see if it works.

Can someone point me to the right place so I can dld it and put my stuff in and see if it works?

Thanks...wine is yummy

Ok, I know why everything failed....cause you're all using the default interface, not MUI2. Not that it really matters now, but here's the correct instructions (also posted in the GameSuitePortable thread) -

1. add !include WinMessages.nsh
2. add these 2 lines to the top of your nsDialogs page function (doesn't work in the .onGUIInit function when using nsDialogs for some reason) -

GetDlgItem $0 $HWNDPARENT 1 ; install button
SendMessage $0 ${WM_SETTEXT} 0 "STR:Start!" ; change text
