My name is Roger Lacroix and I am a die hard programmer. I have been programming since the 80s. My favorite programming languages are Java, C and Rexx. I have worked in the airline, retail but I have spent most of my time doing middleware work in the financial services industry. In 1994, I was introduced to IBM MQ (aka WebSphere MQ & MQSeries) and I thought it was the next best thing since man created fire. This blog will be about IBM MQ, Java, C, Rexx and any other interesting items that I can think of. I hope you enjoy it.

The other day I wrote about working from home, since I recently upgraded both my desktop and laptop to Windows 10 64-bit, I thought I should review/list the open source software I use to get the job done. You don’t need to go broke setting up your PC/laptop with software. Here is a list of […]

An MQ API Exit is configured to run within the queue manager’s address space (or the application’s address space if the application connects in bindings mode to the queue manager). For MQMR v1.1.0, a customer requested that information be added to the replicated messages, so that […]

memmem() Function for a C Program

March 17, 2020 Roger Lacroix
s

Last week, I needed a function for a C program that would search a string not null terminated for a string not null terminated. Hence, I could not use strstr() function because it requires the strings to be null terminated. So, I checked my trusty C Runtime Library Reference and found nothing that matched. Now […]

It is funny that everyone is freaking out about working from home. I always found I got less done at the office than at home because I was always being interrupted every 2 minutes. For most of my career, I have worked part-time at home. In 2001, I incorporated Capitalware and went out on my […]

Java’s Missing Byte Array Class

February 19, 2020 Roger Lacroix
s

After 25 years, it is still surprising that Java doesn’t have a proper byte array class. There can be many reasons that the data a Java program needs to work with is in a byte array. It could be the contents of a file or MQTT message or IBM MQ message, etc. Since there is […]

The person on StackOverflow made a comment that I was using a static string as my reply message. Humm. Some times people cannot see the forest for the trees. So, I have updated my sample Java/MQ (i.e. MQTest77.java) in this posting to do the following: Connect to a remote queue manager Open an input queue, […]
