|

谁能帮我将下面这段VB程序转为VC，赠送50金币。 一段数据采集程序。代码如下： Function readGAM60Value(mingling As String) As Double Dim i%, j%, k%, Buf$, d Dim InByte As String Dim OutB() As Byte Dim aa As String Dim bb, cc As String Dim value As Double MSComm1.PortOpen = True MSComm1.InBufferCount = 0 MSComm1.OutBufferCount = 0 MSComm1.PortOpen = False Buf = "" Buf = Trim(mingling) i = Len(Buf) k = 1 ReDim OutB(i / 2 - 1) j = 0 Do While i > 0 OutB(j) = CByte("&H" & Mid(Buf, k, 2)) k = k + 2 i = i - 2 j = j + 1 Loop MSComm1.PortOpen = True MSComm1.InBufferCount = 0 MSComm1.Output = OutB d = 0 While d < 9000000 d = d + 1 Wend InByte = MSComm1.Input MSComm1.PortOpen = False If Mid(InByte, 1, 1) = "+" Then aa = Mid(InByte, 2, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 2, 1) = "+" Then aa = Mid(InByte, 3, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 3, 1) = "+" Then aa = Mid(InByte, 4, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 4, 1) = "+" Then aa = Mid(InByte, 5, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 5, 1) = "+" Then aa = Mid(InByte, 6, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 6, 1) = "+" Then aa = Mid(InByte, 7, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 7, 1) = "+" Then aa = Mid(InByte, 8, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 8, 1) = "+" Then aa = Mid(InByte, 9, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 9, 1) = "+" Then aa = Mid(InByte, 10, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 10, 1) = "+" Then aa = Mid(InByte, 11, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 11, 1) = "+" Then aa = Mid(InByte, 12, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 12, 1) = "+" Then aa = Mid(InByte, 13, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 13, 1) = "+" Then aa = Mid(InByte, 14, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 14, 1) = "+" Then aa = Mid(InByte, 15, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 15, 1) = "+" Then aa = Mid(InByte, 16, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If If Mid(InByte, 16, 1) = "+" Then aa = Mid(InByte, 17, 10) value = Val(aa) readGAM60Value = value * 0.01 Exit Function End If End Function '获取角度 Private Sub Huoqujiaodu_Click() Dim jiaodu As Double jiaodu = readGAM60Value("2330300D"  Text1.Text = jiaodu End Sub [ Last edited by li343 on 2009-11-18 at 12:21 ] |

1.将该vb代码模块包装成COM控件，就可以在vc中加在调用了。 2.把VB做成Dll文件，在VC中调用就可以了 |

| 改了一下午的代码，发现vb转vc难度很大，很多类型和函数没有，我提个折中的方案，就是在vc里面用shellexecute来调vb编译的exe文件或者直接读取它的结果文件，你看行不行，这个方法，我以前用过的 |
