[求助]請問這兩個API的DynamicWrapper輸入參數數量和類型該怎么寫 [金字塔]
- 咨詢內容：
在VB是這么寫的：
Private Declare Sub CopyMemory Lib "ntdll" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal Length As Long) Private Declare Function StrCSpn Lib "shlwapi.dll" Alias "StrCSpnW" (ByVal lpStr&, ByVal lpCharacters&) As Long
謝謝！！
- 金字塔客服：
建議看看金字塔編程幫助中對DynamicWrapper的參數描述吧，此外DynamicWrapper是公用的控件，你可以到GOOGLE上搜索一下看看有沒有能幫助到你的信息
- 用戶回復：
我看過幫助了
主要是Any類型不知道怎么轉換
查了一下，是變體

到網上一艘一大把
給你找了一篇 VBS調用Win32API示例：對話框
里面有相關累死的代碼調用Option Explicit
