我这里有个API,接口文档中是这样定义其中的一个函数的:
int enter_station(char* sn,char* station)方法一:
VB中声明:
Declare Function enter_station Lib "ateonline.dll" (ByVal sn As String, ByVal station As String) As Long 调用:
Dim sn As String * 50
Dim station As String * 50
sn = "111111111"
station = "22222222222"
Text1.Text = enter_station(sn, station)方法二:
VB中声明:
Declare Function enter_station Lib "ateonline.dll" (ByVal sn As Long, ByVal station As Long) As Long 调用过程:
Function EnterStation(sn As String, station As String) As Integer
EnterStation = ConvertLongToInt(enter_station(StrPtr(sn), StrPtr(station)))
End Function
Dim sn As String * 50
Dim station As String * 50
sn = "111111111"
station = "22222222222"
Text1.Text = EnterStation (sn, station)
int enter_station(char* sn,char* station)方法一:
VB中声明:
Declare Function enter_station Lib "ateonline.dll" (ByVal sn As String, ByVal station As String) As Long 调用:
Dim sn As String * 50
Dim station As String * 50
sn = "111111111"
station = "22222222222"
Text1.Text = enter_station(sn, station)方法二:
VB中声明:
Declare Function enter_station Lib "ateonline.dll" (ByVal sn As Long, ByVal station As Long) As Long 调用过程:
Function EnterStation(sn As String, station As String) As Integer
EnterStation = ConvertLongToInt(enter_station(StrPtr(sn), StrPtr(station)))
End Function
Dim sn As String * 50
Dim station As String * 50
sn = "111111111"
station = "22222222222"
Text1.Text = EnterStation (sn, station)
