gui

I have developped an application that can process data (in my case image algorithms performed on videos). I have developed different ProcessingMethods.

Sometimes several videos are processed in parallel. Each process runs in a seperate thread.

I have a GUI with several ProgressBars, one for each thread that is processing data.

What is a good way to update the ProgressBar?

Today my GUI is creating all the processing threads and one progressBars for each thread. Then I pass those progressBars to the threads, which pass them to the ProcessingMethod. The ProcessingMethod will then update the progressbar (using Invoke(..)).

I have different processingMethods. Within each of these methods I have copy-paste code to update the progressBar. Although I am a new to programming, I know copy-paste is not good.

What is a good way to make it better?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
