    When I grabbed this program, it appeared not to display correctly. It turns out it displayed the FIRST part of the graph, and my Scope shows the middle by default (DS10520E). THANKFULLY it was open source.

    Next, I wanted to be able to Open Multiple Files at once
    Then, I wanted to save the CSV Files, and IMAGES all at once
    Finally, I wanted to have the Image that was on the Rigol when I saved, plus I wanted the ability to save the ENTIRE Wave Form, And I wanted to know the Numbers. (Ch1/Ch2: Vmax,V0ffset,Vmin,Vamp), and have them on the bitmaps, and on the screen.

    I contacted the author, and he said "aren't you glad I made it opensource?" (I still don't know if I want to answer that. I would have rather paid for the changes I wanted, LOL)... Anyways, I dug in, found issues, and stuck with it, until I Found the Missing ChPosOrig[] and ChScaleOrig[]. That got me to finish the core manipulation of the files, calculations and proper Display results for the various files I was playing with...

    Finally, I LOVE Delphi. But I hate having to install everyones PET components to make something compile. I believe this prevents a lot of OpenSource from taking off. In this case, it took me 1/2 a day to get install, and be able to start loading this program so I could get to the code. And the controls were causing nasty flickering when I used them. Out they went. Cool, yes.

    But I want basic, working functionality. I will try to get the multi-lingual stuff back in, because that was functional, but skins? Really? The tough Part is that I do us Jedi VCL. I am avoiding putting it in for one or two things, but it may go in... It is a very popular set of controls... I could use: MRU, FormProperties (Size, Position, etc), or write code... FFPbox Remained, because frankly, PaintBox sucks and flickers. LOL.

    FFPbox is used WITHOUT Installing it. It is just created at run time.

    In closing, my goal really was to have a project you could download and simply compile and use. Or a functional precompiled Demo that you could just use. (And I would love to implement a PreviewPan Preview option, so you can see your WFM Files in windows Explorer without opening! That would make the project complete for me)

    None of this would be possible without the work Vladimir started. Thanks!

    Master TODO:
    - Display Channel Markers/Scaling
    - Voltage Panel Display (Scan through File as we paint, calculated Min/Max Voltages)
    - When Painting the Voltage, Display: Ch1: Mx,0,Mn / Ch2: Mx,0,Mn
    - MRU Files
    - Export JPG
    - Export ALL
