这段vb代码什么意思？ Public Declare Function GdiTransparentBlt Lib "gdi32"

vb程序中的下段代码是什么意思？重点解析gdi32是什么，同时说说declare，谢谢！
Public Declare Function GdiTransparentBlt Lib "gdi32" (ByVal hdc1 As Long, ByVal x1 As Long, ByVal y1 As Long, ByVal W1 As Long, ByVal H1 As Long, ByVal Hdc2 As Long, ByVal X2 As Long, ByVal Y2 As Long, ByVal W2 As Long, ByVal H2 As Long, ByVal Color As Long) As Long

Answer 1

gdi32.dll是Windows图形用户接口链接库,GdiTransparentBlt 就是这个库里面的一个函数
这里Declare 是对这个函数进行声明,声明后你才能使用这个函数
