Over the next few months many of you will be porting your Microsoft® Transaction Server (MTS) applications over to COM+ and Windows® 2000. This month's column examines some of the most significant changes that will affect the way you'll write middle-tier components. I'll assume you know how to create Visual Basic®-based components for applications that employ COM and MTS. Thankfully, there aren't many aspects of component development that will change when you're moving to COM+. Still, some as...

You can write applications that are able to perform multiple tasks simultaneously. This ability, called multithreading, or free threading, is a powerful way to design components that are processor-intensive and require user input. An example of a component that might make use of multithreading would be a component that calculates payroll information. The component could process data entered into a database by a user on one thread while processor-intensive payroll calculations were performed on a...

Serial Port Configuration Dialog

Quite a few times in my hardware projects I had to send some calibration data between a microcontroller (Microchip PIC) and a PC through a serial port (RS-232). The software on the PC side is written in VB6 with an MSComm control. The latter has to be configured with parameters: port number, baud rate, number of data bits, number of stop bits. Configuration of an MSComm is a fairly common task (it used to be even more common in the past). So, at first I thought that there should be a dialog for ...

This article is for ASP developers and Visual Basic (VB) programmers who want to combine both technologies to write compiled VB components for ASP pages. When I reread my initial article, "Creating a Server Component with Visual Basic" (see http://www.15seconds.com/Issue/980930.htm), it struck me that a lot of code has flowed under the bridge since then. I also realized that the way I code a server-side component has dramatically changed from the method described in the previous article. I decid...

I have seen many articles written about this subject for .NET. The problem is that there is something wrong or left out of all of them. Most demonstrate the pattern properly but leave some important information out when it comes to an actual implementation. In the example below, I show you how to create a useful singleton business object class which will load data from the database, persist itself within the application, account for inserts and updates properly, only allow one instance of itself...

What if this rewrite is in a new architecture, using n-tier and common DLLs that most of the new applications will use, cool... however what if once you finished one of your .NET DLLs, you have to integrate that new library into one of your VB6 apps....

One of the main advantages of building components is to promote reusability. For example, if you build a object that represents an invoice, there could be many other projects in your company that can reuse the same object. This concept of re-using components in various projects promotes what is called RAD (Rapid Application Development). Traditional application development environemnts like VB supported this paradigm by making a toolbox available from which developers could pick and choose compo...
