Specifically, VB6 cannot implement class inheritance in the true sense (for example, inheritance in C ++), but implements also provides similar functions. We first create a class module cbase. CLs The Code is as follows: Private mvarbaseproperty as string Public sub basefunction () Msgbox "Hello world !" End sub Public property let baseproperty (byval vdata as string) Mvarbaseproperty = vdata End Property Public property get baseproperty () as stri

System. reflection. missing is a special class dedicated to represent the missing parameter in VB6. This class defined a static field missing. value to represent the sole instance of this class. each time you have to use missing object, you can only refer to this static value, and can not create any new instances. if you are aware of the Singleton pattern, you will understand that.

Data | Database A lot of brothers here ask questions about VB6 reading and writing to a database, and here's an example that I hope is inspiring. 1, with names and related pictures as an example, the database is access, with the following fields: Name char,picture OLE object,filelength number. When you are MS SQL, change the picture to lob. 2, the example contains Control:commom Dialog,picture,listbox. The source code is as follows: Option Explicit P

Speed Unlike. Net, the default in VB6 is to pass arguments by using BYREF, and there seems to be nothing to optimize. But, actually, if you invoke the API, the code copied from the API browser is forced to use ByVal. This gives us a chance to optimize. Combined previously written Use API SendMessage to improve the speed of inserting Vb.combobox Item I again used the code to test a ByRef, ByVal the difference, the result is very exciting: ByRef is 16 t

ado| Create | dynamic | access | control | data | database Using the ADO control can easily access the ODBC database in VB6, but by directly placing adods control to get ADO data connection is troublesome, we can create a common data module in the VB project, the initialization of the ADO control, establish the connection, close the connection and so on the operation all writes to the function, This allows you to share calls to this ADO connection in

My previous question stopped for a long time because-I went to write a book.ObjectiveI started working in March 2012 and now I'm six years away. For the past six years, I have never known anything about SQL Server, only the simplest C # programmers have started, stepping back from a nameless outsourcing company to the middle of a larger financial institution, with wages rising to nearly four times times the size of a new job. In the process of struggle, I also go a lot of detours, once very depr
