List of high priority bugs: VBx compatibility and tB code execution #2010

Bugs concerning VBx compatibility and tB code execution are important to fix for V1 and Wayne needs some help gathering a list of these specifically vs just the general Issues list which is full of feature requests, IDE issues unrelated to program operation, and other things more properly addressed after v1.0's initial release.
And it's a lot of work to re-check everything, so definitely not something I can do alone.
This post is intended for the community to compile a list of all such outstanding bugs. I'll be creating a checklist in this top post, and ask that everyone help out by checking posted bug reports, confirming they're still unfixed in the latest builds, and replying with a link to the report (from any source, GitHub issues, the tB bugs channel, VBForums, or elsewhere; and from any time, there are bug reports from years ago still needing to be fixed) so I can add it to the master list here.

I've done just an initial few to show what we're doing here and what info should be included in issues you check. I'll be working on it a little bit at a time, and hope some of you can check out some bugs too. Just include either the GitHub number or link, and whether you've confirmed it for sure or it's very likely still present but checking needs more info or a lot of effort.

When you find bugs you check and find have been fixed, please post a comment in the post containing the report noting that.

Others

Not sure if a decision was made but the IDataObject from DataObject is a very common hack and if it's going to be a yes compatibility should be available for v1.0

• IDataObject from DataObject #1899

This issue I think needs addressing; it either needs to raise an error like VB6 or preserve the contents per ReDim Preserve IMO.

• ReDim Preserve fails to preserve when the LBound is redimmed #1725

Likely unfixed but needs more info or extensive effort to check
