用于Inno设置的序列号的CustomPage [英] CustomPage for Serial Number in Inno Setup

问题描述

如何在Inno Setup中使用序列号编辑框创建CustomPage? 例如. 6x5chars或7x5chars?

How to create CustomPage in Inno Setup with Edit Boxes for Serial Number? E.g. 6x5chars or 7x5chars?

脚本应在下一步"按钮可用之前检查是否所有框都已填充.

Script should check if all boxes are filled before Next button become available.

如果剪贴板中的内容与序列号格式匹配，则可以实现复制/粘贴功能以允许填写所有编辑框"，这也很好.

It would be also good if there could be Copy/Paste function implemented that would allow to fill up all Edit Boxes if the clipboard content matches the serial number pattern.

推荐答案

这里是使用自定义页面(在其中创建单独的编辑框)的一种方法.您只需要指定SC_EDITCOUNT常量的值，即可定义编辑框的数量，而SC_CHARCOUNT可以在这些编辑框中输入的字符数是什么.如果您在第一个编辑框中，则可以粘贴整个序列号，如果序列号采用-字符(此处为TryPasteSerialNumber函数)定界的格式，则可以粘贴该序列号.要从编辑框中获取序列号，只需调用GetSerialNumber即可，您还可以在其中指定输出格式的定界符(如果需要).

Here is one approach that uses the custom page where the separate edit boxes are created. You only need to specify the value for the SC_EDITCOUNT constant where the number of edit boxes is defined and the SC_CHARCOUNT what is the number of characters that can be entered into these edit boxes. If you are in the first edit box you may paste the whole serial number if it's in the format by the pattern delimited by the - char (the TryPasteSerialNumber function here). To get the serial number from the edit boxes it's enough to call GetSerialNumber where you can specify also a delimiter for the output format (if needed).
