需要InstallOptionsEx驗證的一些幫助。在InstallOptions我們使用標誌=通知，然後我們在功能NSIS InstallOptionsEx驗證
ReadINIStr $0 "$PLUGINSDIR\test.ini" "Settings" "State"
StrCmp $0 0 validate ; Next button?
StrCmp $0 2 supportx ; "Install support for X"?
StrCmp $0 9 clearbtn ; "Clear" button?
StrCmp $0 11 droplist ; "Show|Hide" drop-list?
Abort ; Return to the page
沒有服用點這樣但在InstallOptionsEx他們說，他們贊成新方法廢除了它。
這是從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 $0 "" 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.
有人可以幫我找出新的方法？如果你看下面的代碼文件有一箇舊的和新的部分，並在新的部分，你會看到我想要做的。需要幫助的代碼。
這裏是一個INI文件和代碼文件：
