为什么用 api viewer 声明的函数不能用？Shell_NotifyIcon?

长安宁 2004-08-18 05:42:53

为什么在 api viewer 里面声明的函数
Private Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long

在VB里面翻译的时候总是显示“用户定义类型未定义”，请速答！！
谢谢！！

cbSize As Long '
hWnd As Long '
uID As Long '
uFlags As Long '
uCallbackMessage As Long '
hIcon As Long '
szTip As String * 64 '
end Type

在模块里先定义这个类型.然后再声明,还有api viewer 里面声明的这个函数有错误,正确声明是:
Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long

Dim aa As NOTIFYICONDATA

把aa当参数传进去就可以了
