Question

我在我的nsi脚本中添加了一个${NSD_CreateIPaddress}框，但默认情况下，验证每个IP字段的时间是0。我使用${GetText}获取IP地址值。

有没有办法删除默认值0并验证每个IP地址字段。请帮帮我。

Answer 1

我不确定你在问什么。如果要区分空白地址和有效“0.0.0.0”地址，可以使用IPM_ISBLANK消息。不需要验证各个字段，因为它们已经限制为0..255，您甚至可以使用IPM_SETRANGE.设置自定义范围

如果您仍然觉得需要查看各个字段

A）手动解析您自己从$ {NSD_GetText}获得的字符串。

或

B）解压缩您从IPM_GETADDRESS获得的32位地址：
