I will try to be more straight-forward about what I need to do. As you probably already know, I am a beginner programmer. I go to college and currently, I am working in an internship. My task is to learn libnodave as much as I can. The other part of my task is to use a program and modify it to where it can read and/or write a PLC without being connected. (the current program used to connect PLCs sometimes crashes at the connection, but this program is written in VB) My boss is the person who wrote the VB code that he uses. However, he is not very knowledgeable in C++. I only have one or two basic courses in C++, but am trying to find a way to complete my task. It is very rare for the connection to crash, but we want to make the read and write method safe from ever being interrupted. This is the reason for my question. Again, I don't mean to clutter with my questions, just looking for a little help.
@Zottel, I did see your response at the other thread but was a little confused and looking for a little more detail, hence my other thread.
Thank you
