运行VB工程没问题，但是生成EXE后运行，报内存错误~~
程序是通过摄像机返回的图像识别车牌，然后把车牌通过串口发送到IDE上显示，下面是代码，cpsb_HavePlates是识别到车牌的事件，sendPlateToLED是发送车牌到IED，在运行生成的EXE的时候如果我把sendPlateToLED (plateName)屏蔽没问题，如果我加上的话就报内存错误，直接运行工程都没问题。。。
Private Sub cpsb_HavePlates(ByVal strPicName As String, ByVal strPlateName As String, ByVal strPlateColor As String, ByVal trPlateType As String)
Dim picName, plateName, plateColor, plateType, driection As String
driection = cpsb.GetDriection
If driection = "向上行驶" Or driection = "向左行驶" Then
Exit Sub
Else
isOK = False
plateName = strPlateName
Label3.Caption = plateName
'Label3.Caption = driection
plate = plateName
sendPlateToLED (plateName)
End If
End Sub
Private Function sendPlateToLED(ByVal plateName As String)

在sendPlateToLED (plateName)前加Call
--------------------编程问答--------------------
没解决问题. --------------------编程问答-------------------- 主要是你们没法调试得，我在想，是不是在用户自定义事件里面调用了其它函数，会出现问题。。。 --------------------编程问答-------------------- 用户自定义事件里面调用了其它函数不会出现问题，lz的代码需要调试才能确定问题所在，感觉是cpsb_HavePlates函数调用前有影响后面运行的代码。vb ide环境中运行工程时属于debug环境，编译后代码优化了可能影响某些函数特别是和硬件接口函数性能。 --------------------编程问答-------------------- 这个难于判断，我觉得可能是硬件驱动的问题。 --------------------编程问答-------------------- 主要是别人的OCX，我也不知道cpsb_HavePlates是咋写的，而且运行这个OCX还要加密狗。。。。纠结。。。
补充：VB , 基础类
