methods - Need plan of action to upgrade graphics toolkit in company's applications -

-

My job is to upgrade all our applications, which are OpenSceneGraph (an OpenGL Toolkit) version 0.9.9 latest and greatest 2.8 Well some weaknesses come with this task:

1. After version 9.9) there was a major overhaul of the core OpenGraph graph (OSG). Generally used tasks and classes were added and removed. Simply put, I can not just replace the old place with the new ones and modify some degraded or deleted works - there is a lot to be changed.

2.) Our applications were used in MFC Visual Studio 2003. They would have to stay with the use that I want to upgrade.

3.) For the OSG, good organized documents can be found for my special scanner and the best of unrelated and scattered.

My question is: what will be the approach in some broad way to deal with this problem. I have about two weeks to upgrade one of the applications, then the plan is to follow and implement this approach for the rest of the applications. For me, the biggest obstacle is getting the starting point. I work on most projects, I easily dig into the right area and can do it with a little organization and plan. It seems like a slightly more complex problem, with a more precise and accurate plan of action. Your thoughts and suggestions are highly appreciated. In my opinion, you should upgrade your OG to the new version and

Every exception is not easily solved until you try to make it again, you can ask from the osg mailing list.

You can ask if there are major changes with your current version and latest version.

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
