NSIS 脚本不显示服务状态

Question

我在脚本末尾创建了一个部分，它应该显示我的服务状态，但在执行后没有显示消息框。可能是什么原因？

Section "Create Service"
  ExecShellWait '' 'sc.exe' 'create myservice error= "severe" displayname= "myservice" type= "own" start= "auto" binpath= "$INSTDIR\MyService.exe"' SW_HIDE
SectionEnd

Section "Start Service"
  ExecShellWait '' 'sc.exe' 'start myservice' SW_HIDE
SectionEnd

Section "Ensure Running"
  StrCpy $R0 '"$SYSDIR\cmd.exe" /c "sc QUERY myservice | FIND /C "RUNNING""'
  nsExec::ExecToStack '$R0'
  Pop $R1  # contains return code
  Pop $R2  # contains output
  ${If} $R1 == "0"    
  DetailPrint "checking if command is success"
    ${If} $R2 == "1"
        MessageBox mb_ok "myservice is Running"   # it's running
    ${Else}
        MessageBox mb_ok "Not Running"        # it's not running
    ${EndIf}
  ${Else}
  DetailPrint "command failed"
  ${EndIf}  
SectionEnd ```


 nsExec::ExecToStack /OEM '$R0' didn't change anything. During installation it rushes to finish page after sc exec ..Do I need to add additional page page here ?

!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_LICENSE ..\license.rtf
; Page custom pageRegistration
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_PAGE_FINISH
!insertmacro MUI_LANGUAGE English

没有看到输出，我只能猜测存在某种 Unicode 问题。

将 nsExec::ExecToStack '$R0' 更改为 nsExec::ExecToStack /OEM '$R0'。

也就是说，我不知道运行字符串是否总是英文的。您可以使用 NSIS wiki 上的几个服务插件和宏。

或者你可以使用这个：

!include "LogicLib.nsh"
!include "Win\COM.nsh"
!include "Win\Propkey.nsh"
Function IsServiceRunning
Exch [=10=]
Push 
StrCpy  [=10=]
!insertmacro ComHlpr_CreateInProcInstance {13709620-C279-11ce-A49E-444553540000} {A4C6892C-3BA9-11D2-9DEA-00C04FB16162} r0 "" ; IE5+?
${If} [=10=] P<> 0
    System::Call "[=10=]->36(wr1,@r1)i.s"
    ${IUnknown::Release} [=10=] ""
    Pop [=10=]
    ${If} [=10=] >= 0
        StrCpy [=10=] 0
        Push 
        ${V_GetVT}  r2
        ${V_GetBOOL}  r1
        ${If}  = ${VT_BOOL}
        ${AndIf}  <> ${VARIANT_FALSE}
            StrCpy [=10=] 1
        ${EndIf}
        Pop 
    ${Else}
        StrCpy [=10=] 0
    ${EndIf}
${EndIf}
Pop 
Exch [=10=]
FunctionEnd

Section "Example"
Push "RemoteRegistry"
Call IsServiceRunning
Pop [=10=]
DetailPrint "RemoteRegistry running=[=10=]"

Push "Themes"
Call IsServiceRunning
Pop [=10=]
DetailPrint "Themes running=[=10=]"
SectionEnd
