NSIS InstallOptionsEx 验证

Question

需要有关 InstallOptionsEx 验证的帮助。在 InstallOptions 中我们使用 Flags=Notify 然后我们在函数

中做了这样的事情

  ReadINIStr [=10=] "$PLUGINSDIR\test.ini" "Settings" "State"
  StrCmp [=10=] 0 validate  ; Next button?
  StrCmp [=10=] 2 supportx  ; "Install support for X"?
  StrCmp [=10=] 9 clearbtn  ; "Clear" button?
  StrCmp [=10=] 11 droplist ; "Show|Hide" drop-list?
  Abort ; Return to the page

但在 InstallOptionsEx 中，他们说他们取消了它以支持新方法。

这来自 InstallOptionsEx 自述文件：

 Step 5: Validate the Output 
If you want to validate the input on the page, for example, you want to check whether the user has filled in a textbox, use the leave function of the Page command and Abort when the validation has failed:
  Function ValidateCustom

    ReadINIStr $R0 "$PLUGINSDIR\test.ini" "Field 1" "State"
    StrCmp [=11=] "" 0 +3
      MessageBox MB_ICONEXCLAMATION|MB_OK "Please enter your name."
      Abort

  FunctionEnd

  Step 6: Return Value 
After you have called the DLL, InstallOptionsEx adds one string to the stack, with one of the following values:
success - The user has pressed the Next button
back - The user has pressed the Back button
cancel - The user has pressed the Cancel button
error - An error has occurred, the dialog cannot be displayed.
Usually, you don't need to check this value, but you still have to remove it from the stack (have a look at the example above).
You only have to check this value if you need something really special, such as doing something when the user pressed the Back button.

谁能帮我想出新方法？如果您查看下面的代码文件，就会有一个新旧部分，在新部分中您会看到我正在尝试做什么。需要有关代码的帮助。

这是一个ini文件和代码文件：

Answer 1

好吧，我终于弄明白了，虽然我会 post 以防其他人需要。

我有这个：

Function ShowCustom
  InstallOptionsEx::initDialog "$PLUGINSDIR\pagesetup.ini"
  Pop [=10=]
  InstallOptionsEx::show
  Pop [=10=]
FunctionEnd

它应该是这样的：（Ex 不应该在那里）

Function ShowCustom
  InstallOptions::initDialog "$PLUGINSDIR\pagesetup.ini"
  Pop [=11=]
  InstallOptions::show
  Pop [=11=]
FunctionEnd

那就用电流检查一下

  ReadINIStr [=12=] "$PLUGINSDIR\test.ini" "Settings" "State"
  StrCmp [=12=] 0 validate  ; Next button?
  StrCmp [=12=] 2 supportx  ; "Install support for X"?
  StrCmp [=12=] 9 clearbtn  ; "Clear" button?
  StrCmp [=12=] 11 droplist ; "Show|Hide" drop-list?
  Abort ; Return to the page
