Question

我有一个NSIS脚本，有两个要卸载的组件。如果用户取消选中＆＃34;选择组件＆＃34;页面，卸载按钮仍处于活动状态，卸载过程可以继续，而无需实际卸载任何内容。是否有任何简单的方法可以禁用＆＃34;卸载＆＃34;如果没有选择组件，按钮？选择卸载程序部分的代码如下：

# Macro for selecting uninstaller sections
!macro SELECT_UNSECTION SECTION_NAME UNSECTION_ID
    Push $R0
    ReadRegStr $R0 HKLM "${REGKEY}\Components" "${SECTION_NAME}"
    StrCmp $R0 1 0 next${UNSECTION_ID}
    !insertmacro SelectSection "${UNSECTION_ID}"
    GoTo done${UNSECTION_ID}
next${UNSECTION_ID}:
    !insertmacro UnselectSection "${UNSECTION_ID}"
done${UNSECTION_ID}:
    Pop $R0
!macroend

提前致谢！

UninstPage Components un.InitComponents
UninstPage InstFiles

Section "un.Foo" SID_FOO
SectionEnd
Section /o "un.Bar" SID_BAR
SectionEnd

!include LogicLib.nsh

Function un.InitComponents
;!insertmacro SELECT_UNSECTION SECTION_NAME ...
Call un.onSelChange ; Make sure the initial button state is correct
FunctionEnd

Function un.onSelChange
GetDlgItem $1 $hwndParent 1
${If} ${SectionIsSelected} ${SID_FOO}
${OrIf} ${SectionIsSelected} ${SID_BAR}
    EnableWindow $1 1
${Else}
    EnableWindow $1 0
${EndIf}
FunctionEnd
