API的函数声明

技术2022-05-11 52

以前在VB6的时候声明一个API是这样的

Declare Function FlashWindow Lib "user32" Alias "FlashWindow" (ByVal hwnd As Long, ByVal bInvert As Long) As Long 你看出来了么？

现在在VB.NET里声明同一个API是这样的

Declare Function FlashWindow Lib "user32.dll" ( ByVal hwnd As Int32, ByVal bInvert As Int32) As Int32

其实在VB.NET里应该是这样的

Declare Function FlashWindow Lib "user32.dll" (ByVal hwnd As IntPtr,ByVal bInvert As Int32) As Int32
