• 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.

P3D v4 Capture HDC of Exisiting gauges?

Is it possible using a gauge to capture the HDC of other gauges that are installed in the panel, can I access those gauge's element lists?

Thanks!

You should be able to do this, remember gauges are just DLLs in the same memory space as your DLL and the sim. Look carefully at the macro that help in defining gauges, these macros defined in "gauges.h" should help you understanding how the gauge DLLs are built and how to access their data.

For any gauges that utilize a separate thread to do rendering, you run a severe risk of a memory collision of sorts. Also, only gauges that use an HDC (defined by the IMAGE_CREATE_DIBSECTION flag) actually have an HDC at all.

Thanks gents! I've got my own DLL gauges going, more as an experiment I was looking just to read and copy the pixel data from those HDCs so that may avoid the memory collision but I really appreciate the feedback!
