• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

GDI+ Gauges Tutorial

I have quite a bit of information available as "sticky posts" in my forum at http://flightsim.com "Panel and Gauges" as well as my Wiki page...

I noticed from looking through your makefile that you are compiling the SDK example gauges. I actually had created a VS 2005 "Solution" for that several years ago, and made it available on request.

I also have a C++/GDI+ template "Solution" available on request to me at n4gix@comcast.net...

I make no pretense that it's the only -or even the best!- approach to the subject, but it has the advantage of being well-structured and gives beginners a place to start... :D

Dear Bill:

Could you give me your solution for the C++/GDI+ template, please?

Do you know how to smooth the slider movement, I have a glide slope (slider) that moves making small jumps.

Do you know a good website to upload my Russian gauges?

When dealing with bitmaps, the smoothness of movement is proportional to overall size of the gauge's background.

Keep in mind that by their nature, bitmaps may only be shifted in position by one pixel increments... ;)

So, if you need to shift a horizontal line vertically between a range of +/- 127, then you will require at least 254 pixels in the y axis for a 1:1 movement...
