问题 In my VB6 application I have an array of objects declared thus... Dim MyArray() as MyClass This array is filled in as processing goes on Set MyArray(element) = passed_object and as elements are no longer wanted, Set MyArray(otherelement) = Nothing When using the array, I want to use a loop like For i = 1 To Ubound(MyArray) If MyArray(i) <> Nothing Then ' Doesn't compile ...do something...

问题 I am trying to declare a variable in a VB6 module as follows: Public WithEvents MyObject As MyClass The help files say that WithEvents can only be used in class modules. Why can't it be used in .bas modules? The legacy code I am working has an object declared globally in a module. I want to add WithEvents to this declaration but I need to keep the object global because many other forms etc refer to the object. How can I achieve this with minimal disruption to the code? 回答1: Write a class that

问题 I'm having problem with ODBC and an application written with Visual Basic 6 (so it's 32-bit). It seems that the ODBC library of VB6 is not compatible with the 64-bit ODBC of Windows 7. The error code returned is -2147220992 and it's rambling about incompatible architectures. Can I install a 32-bit version of ODBC? Or any other alternatives? 回答1: use the 32-bit odbc manager to add your DSN: C:\Windows\SysWOW64\odbcad32.exe that should be able to see the 32-bit odbc driver. 回答2: You need to use

The primary difference is that a VB 6 Collection is not strongly-typed , which means that all objects are stored as Variants in the collection

问题 @UPDATE: OK FOR ANYONE ELSE WHO IS SEEKING ADVICE ON THIS ISSUE... So far, the best thing i have found is to download yourself a cpy of pGina (http://www.pgina.org/) and for 2k/xp modify the GINA, and for vista/win7 you will need to create custom login credentials (pGina have the tools/samples to interface with the vista/win7 architecture). to confirm -- it appears that this is what Novell are doing with vista/win7 rather than the traditional method of replacing the GINA (like in 2k/xp) If
