Nsis服務刪除

Question

你好，我有NSIS卸載程序的問題。

我安裝了軟件並創建了一項服務。服務名稱由用戶命名（例如troll）

Soo我有服務troll它正在運行並且正常工作一切正常。

如果我想要卸載軟件，我必須刪除此服務;我已經嘗試了幾種方式與插件simpleSC和nsSCM，沒有什麼幫助我。

如果我寫了前：

• nsSCM::Remove "troll"服務被刪除
• 但是當我寫nsSCM::Remove "$0" - >沒有發生

哪裏是我的錯？從堆棧獲取服務名稱？我不知道該服務的名稱，因爲它是自定義的，任何幫助都將有所幫助：D

Answer 1

安裝程序中的變量內容不會在卸載程序中自動恢復。您必須在註冊表或安裝程序中的.INI文件中寫入服務名稱，然後在卸載程序中讀取該值。

Answer 2

我沒有任何聲望，否則就會發表評論。無論如何，你說這個服務的名字是「」，用戶名爲「

你是說最終用戶指定服務名稱還是隻是最終用戶的用戶名？

如果是後者，你可以使用這個沒有任何插件，不包括ExecDos：如果它是第一個選項，那麼你需要做這樣的事情在你的安裝程序，只要用戶指定服務的

Var User 

!define SVC `$User` 
!define SC `$SYSDIR\sc.exe` 

System::Call "advapi32::GetUserName(t.r0,*i${NSIS_MAX_STRLEN})i" 
StrCpy $User $0 
ClearErrors 
ExecDos::Exec /TOSTACK `"${SC}" stop "${SVC}"` 
Sleep 50 
ExecDos::Exec /TOSTACK `"${SC}" delete "${SVC}"` 

名稱。希望這不是太複雜。

;= I don't know the code you're using but let's assume 
;= after the end-user specifies the service's name you 
;= copy the name to the variable $UserService. This is 
;= somewhere in the install process. 


StrCpy $UserService $0 
;#=# 
;# This will write to an INI file | $EXEDIR\InstallData.ini 
;#  [Service] 
;#  Path=X:\Path\to\service\exe 
;#  Name=ServiceName 
;#=# 
${Service::QueryConfig} ${SVC} /DISABLEFSR $0 $1 

;=# 
;= Then in your uninstaller you could simply implement 
;= this into your code for easy removal. I usually use 
;= this method in my projects and it works pretty good 
;= without the need for any extra plugins. 
ReadINIStr $0 "$EXEDIR\InstallData.ini" "Service" Name 
${Service::Stop} "$0" /DISABLEFSR $0 $1 
Sleep 50 
${Service::Remove} "$0" /DISABLEFSR $0 $1 

的/DISABLEFSR參數應該只在x64機器。但是，如果你搞砸了宏中有一個失敗保險，它會爲你避開這顆子彈。男孩，這很多，是吧？對我來說，這絕對不會幫助你。大聲笑。希望這可以幫助別人。
