Hi Karl,

The parent OnPaint() method of the PictureBox class is PROTECTED, message says that when you override this method in a subclass, it can't have different visibility, so you need to make it PROTECTED as well. Vulcan was doing this automatically.

Hi xinjie,

Thanks, I see the problem, it's because in this line:

This.KeyDown += myCheckBox_KeyDown

the compiler does not know what "myCheckBox_KeyDown" represents, so adds code that tries to resolve it at runtime (to a memvar or similar) and that fails. You can fix this by explicitly specifying ...

Hi Karl,

My old session (for vulcan) was included in 2023's session material, in the folder "Old sessions", but I'm attaching it also here:

Regarding rotation, have a look in the GDI+ demo code, in the method DrawWave(). Basically you need to

Hi Irwin,

Great, thanks for the feedback! Btw, it's too late to include this change in the upcoming build, as the installer is already tested and ready, so after installing it (should be out very soon), please apply again the new dll.

HI xinjie,

Can you please zip and post the complete solution so we can have a look? This will help with reproducing for sure the problem, because with the forms designer there can be a lot of variables at play.

Robert, Irwin,

A new dll for testing the fix can be found here: https://github.com/X-Sharp/XSharpPublic ... 2589567931

Hi Irwin,

This contains a single .exe file (installer)

The other files you downloaded as Jamal said are plugins for XIDE. Maybe we should make the X ...

Hi Irwin,

Sorry, I had missed this one before, but I now checked it and it is a bug, also VO can open dbf files without an extension, but X# currently doesn't. Will open a ticket for this now.

Hi Robbie,

The installed zip file contains an installer as an .exe, you just need to simply run that.

Regarding the third party library, do you have the source code of it? If yes, maybe it's not difficult to convert it to X# also. Or is it a library not written in VO? In that case, yes, it can ...
