Would you like PublicNotCreatable or GlobalSingleUse? These strange terms are COM features. Create a class module in VB6, and look at its Instancing property. The object-orientation in VB is that of COM objects, which is why it doesn't do inheritance (COM is based on interfaces). It is not just a good COM client or server it is a COM product. VB gets its component abilities from COM. Without ActiveX, VB would have been severely underpowered. These components were built mainly using C++, but used mainly from VB. For this reason, VB created a highly successful third-party industry in components, mostly ActiveX controls. It was intended to be a language for high-level composition of low-level components, a glue language if you like.
The truth is, VB was never intended to be a complete development language. Some things that you could do in C++ or in Borland’s Delphi could not be done in VB, or could be done only by monstrous hacks.

Developers bemoaned its lack of full object-orientation and its many anomalies. At the time, VB6 was a popular product, but also the source of considerable discontent. VB6 was first released in September 1998, so it was due for an update. NET were coming together, Microsoft looked at Visual Basic 6.0 and wondered what to do about it. So what has this got to do with Visual Basic? I assume that sometime around the year 2000, when the plans for. Indigo is built on the second version of the. Indigo is also the new standard for XML Web Services, message queuing, transaction management and remote objects, and even inter-process communications. Indigo replaces COM+, the COM-base transaction server which is key to distributed Enterprise applications on Windows. Today, with the family of technologies called Indigo, the extent of this move is becoming even more apparent. NET, but the move away from COM was necessary in order for the Microsoft platform to remain viable. If industry politics had allowed, It could have moved towards Java rather than. I think we should assume that the company would not have done so if there had been a good alternative. It is hard to understate the significance of Microsoft’s shift from COM to. It is also designed for ease of development, and has many security and versioning features that could not easily be added to COM. NET has a loosely-coupled architecture, idea for Internet and mobile applications.

It also has versioning problems, causing software failures.īy contrast. It is highly complex, which was one of the reasons developers were moving from VB to Java. It is a tightly-coupled binary standard, which makes it frail for Internet applications. NET it’s a bit out of date, but mostly still applies. I’ve already written about the rationale behind. NET Framework is Microsoft’s replacement for COM. A third COM standard is OLE (Object Linking and Embedding), used when you insert an Excel spreadsheet into a Word document. There is also COM automation, used in Microsoft Office and elsewhere to control one application from another. One of them is ActiveX controls as found in both Internet Explorer and Visual Basic.

It is a binary standard, so it works with compiled code at runtime. So what is COM? Essentially, it is a mechanism for linking software components together. Second, there is COM, which stands for the Component Object Model.

Every Windows programming tool compiles code that calls the Windows API. By this I mean the low-level programming interface to Windows, as explained in books like Charles Petzold’s Programming Windows. To think this through, we need to hold in our minds three things.įirst, there is the Windows API. Developers expressed emotions ranging from frustration to anger. That caused rumblings that continue today. Back in 2002, it announced that the language was to be replaced by something new, different and incompatible.
Yet Microsoft took this asset, of incalculable value, and apparently tossed it aside. Microsoft had perhaps the largest number of developers in the world hooked on a language which in turn was hooked to Windows.
