Talk:NSIS Service Lib

I noticed that I couldn't create an "interactive" service using your otherwise excellent lib...here's the fix!

Old code:

---

199      !insertmacro CALL_GETPARAM $R4 "interact" "0x10" "lbl_interact"
200        StrCpy $6 0x10
201        IntCmp $R4 0 +2
202        IntOp $R4 $6 | 0x100
203        StrCpy $R4 $6
204      lbl_interact:

New code:

---

199      !insertmacro CALL_GETPARAM $R4 "interact" "0x10" "lbl_interact"
200        StrCpy $6 0x10
201        IntCmp $R4 0 +2
202        IntOp  $6 $6 | 0x100
203        StrCpy $R4 $6
204      lbl_interact:

The (very slight) change is on line 202.

Thanks again,

Nathan Probst

You're correct. I've applied the fix, thanks.

There is a tiny bug that makes the original registers swapped after the function Old code:

I use this patch to avoid some possible quote problem and that add a setdesc to set description (CreateService threat empty dependencies and empty password as NULLs) Also I used some Unicode versions instead of ANSI

Usage Examples

• Stop a service whose name defined in macro

!insertmacro SERVICE stop "${SERVICE_NAME}" ""

• Create a service using macros for name; no newlines in the arguments

!insertmacro SERVICE create "${SERVICE_NAME}" "path=$INSTDIR\x-win32.exe;autostart=1;interact=0;display=${SERVICE_DISPLAYNAME};description=${SERVICE_DESCRIPTION};"
