使用NSIS脚本将文件写入漫游文件夹

Question

我正在使用NSIS为c#中的桌面应用程序制作exe，我必须为用户写几个文件到AppData漫游文件夹

我试过下面的代码

 !define ROAMING_FOLDER_ROOT "$APPDATAAPPDUMMYAPPFILES"
 MessageBox MB_OK 'AppDATA FOLDER "${ROAMING_FOLDER_ROOT}"'  #here i am getting the correct path of the Appdata roaming folder frm variable
Section -Additional
SetOutPath "$ROAMING_FOLDER_ROOT"
SetOverwrite off 
File "C:MYAPPSOURCECODEBINBookStore.sqlite"
SetOverwrite ifnewer
File "C:MYAPPSOURCECODEBINAppSettings.xml"
File "C:MYAPPSOURCECODEBINResourcesdefData.xml"
File "C:MYAPPSOURCECODEBINResourcesdummy.html"
SetOutPath "$ROAMING_FOLDER_ROOTResources"
File "C:MYAPPSOURCECODEBINResourcesappjsfile.js"
SectionEnd

而我试图做同样的$LocalAppData写入AppDAta本地文件夹，但我想使其可写入漫游文件夹

Answer 1

如果您查看您发布的代码，您会看到在MessageBox调用中引用了${ROAMING_FOLDER_ROOT}定义，但在调用SetOutPath时，您引用了一个名为$ROAMING_FOLDER_ROOT的变量，这可能会产生编译器警告。确保在访问定义时使用${}语法!

NSIS有一个叫做shell上下文的概念，$AppData常量受此影响:

SetShellVarContext current ; Current is the default
DetailPrint AppData=$AppData ; C:Users%username%AppDataRoaming
SetShellVarContext all
DetailPrint AppData=$AppData ; C:ProgramData (This is in the All Users folder on XP)
SetShellVarContext current ; Restore it back to the default

Answer 2

看来，您正在使用普通的shell上下文尝试设置

SetShellVarContext current

在你得到$APPDATA之前。

 Var ROAMING_FOLDER_ROOT 
 MessageBox MB_OK 'AppDATA FOLDER "${ROAMING_FOLDER_ROOT}"'  #here i am getting the correct path of the Appdata roaming folder frm variable
Section -Additional
SetShellVarContext current
StrCpy $ROAMING_FOLDER_ROOT "$APPDATAAPPDUMMYAPPFILES"
SetOutPath "$ROAMING_FOLDER_ROOT"
SetOverwrite off 
File "C:MYAPPSOURCECODEModelsBookStore.sqlite"
SetOverwrite ifnewer
File "C:MYAPPSOURCECODEBINAppSettings.xml"
File "C:MYAPPSOURCECODEBINResourcesdefData.xml"
File "C:MYAPPSOURCECODEBINResourcesdummy.html"
SetOutPath "$ROAMING_FOLDER_ROOTResources"
File "C:MYAPPSOURCECODEBINResourcesappjsfile.js"
SectionEnd
