NSIS正在读取1页上的2个目录路径

使用NSIS Dialog Designer,我设计了一个页面,其中有两个组框,每个组框都有一个目录输入控件。

InstallLocation.nsddef 详情如下:

<?xml version="1.0" encoding="UTF-8"?>

<Dialog Name="InstallLocation" Title="Install Locations" Subtitle="Select the paths">
  <CreateFunctionCustomScript>#Set currently saved values for the fields
${NSD_SetText} $hCtl_InstallLocation_FirstInstallDir_Txt $R0
${NSD_SetText} $hCtl_InstallLocation_SecondInstallDir_Txt $R1</CreateFunctionCustomScript>
  <GroupBox Name="GroupBox2" Location="27, 148" Size="376, 68" Text="Select the second path. eg C:\PQR" TabIndex="0">
    <DirRequest Name="SecondInstallDir" Location="6, 28" Size="342, 20" TabIndex="0" ButtonText="Browse..." ButtonWidth="70" />
  </GroupBox>
  <Label Name="Label1" Location="27, 8" Size="424, 38" Text="Select both the paths." TabIndex="1" />
  <GroupBox Name="GroupBox1" Location="27, 64" Size="376, 68" Text="Select the first path. e.g. C:\ABC" TabIndex="2">
    <DirRequest Name="FirstInstallDir" Location="6, 28" Size="342, 20" TabIndex="0" ButtonText="Browse..." ButtonWidth="70" />
  </GroupBox>
</Dialog>

以及相应的 InstallLocation.nsdinc 详情如下:

        ${EndIf}
    ${EndIf}
FunctionEnd

正如你所注意到的,我 CreateFunctionCustomScript 当我从安装程序将读取的属性文件中预填充值时,设置如下:

  ${NSD_SetText} $hCtl_InstallLocation_FirstInstallDir_Txt $R0
  ${NSD_SetText} $hCtl_InstallLocation_SecondInstallDir_Txt $R1

在我的 .nsi 脚本中,我试图将上述路径读入局部变量,如:

Page custom InstallLocation_Show InstallLocation_Leave
Function InstallLocation_Show
    #Initialise temp variables
    StrCpy $R0 $firstInstallPath
    StrCpy $R1 $secondInstallPath
    Call fnc_InstallLocation_Show
FunctionEnd
Function InstallLocation_Leave
    ${NSD_GetText} hCtl_InstallLocation_FirstInstallDir_Txt $R0
    ${NSD_GetText} hCtl_InstallLocation_SecondInstallDir_Txt $R1
    StrCpy $firstInstallPath $R0
    StrCpy $secondInstallPath $R1
    #Ensure values are entered in both fields
    StrCpy $message ""
    ${if} $R0 == ""
    ${OrIf} $R1 == ""
        StrCpy $message "$message both folders are required $\r$\n"
    ${EndIf}
    ${if} $message != ""
        MessageBox MB_OK|MB_ICONQUESTION $message
        Abort
    ${EndIf}
FunctionEnd

所以,直到用户不选择这两条路径,一个弹出窗口将继续与消息一起出现 both folders are required .

然而,它并没有像我期望的那样工作。

即使在我选择了两条路径之后,消息框仍会不断弹出,我无法选择 Next 转到我的下一页。

我理解这是因为两个单击函数都在 $R0 .但我不知道在dialog designer中应该做些什么,这样第一条路径的值就会进入 R0美元 第二条路径的价值就在这里 $R1 ?

我现在已经花了几个小时试图弄清楚在dialog designer中要做什么,或者如何修改我的 nsi先生 正确读取路径并使验证弹出窗口正确运行的逻辑。
