Getting Started

Installation process see $/docs/Chem4Word-Version3-1-Developer-SetUp.docx
Software dependencies Office 2010/2013/2016/2019/365 (Installed on Desktop)
Latest releases

Build and Test

The Chemistry for Word Add-in (Chem4Word) is contained within a single Visual Studio solution located at src/Chem4Word.V3-1.sln This solution has two main projects (use Set as Start Up then run the project), from time to time there may be other utility or PoC projects.

Chem4Word.V3 is the Add-In
WinForms.TestHarness this allows testing of a the Editing subset of operations without starting MS Word

All unit tests are written with XUnit

Describe the bug
Shortcut key does not work on certain situation

To Reproduce
Steps to reproduce the behavior:

Open a new document
Draw a new structure, for example
ctrl+z, nothing happened.
select "delete" button, ctrl+z
select "draw" button, draw whatever structure, ctrl+z now works as expected.

Side note: could you add ctrl+d for deselection?

Expected behavior
ctrl+z should work when whatever button is selected.

Draw ring structure at different angle

In previous version, ring structure can be drawn at different angle by long press and then rotate.

Terminal double bond placement error

After I specifically set the placement as clockwise and anticlockwise, it still display as none.

Another example

Error when inserting chemistry from the navigator

Describe the bug
The user gets an error message when inserting chemistry from the navigator

To Reproduce
Steps to reproduce the behaviour:
Unknown, but telemetry shows that Copy button pressed twice.
As far as I can tell the double click protection of the buttons is working.

Bundling of the Essential Oil structures with Chem4Word

When we release Chem4Word we bundle a standard library with it, for illustrative purposes. I was wondering if there would be any objections to our using the 2100 structure library we have generated as part of the CEVOpen project. The structures are very nice indeed and show off our custom display component brilliantly.
If it isn't OK then please let me know.

Drawing of Markush Bond

*Dear Team,

Thank you for sending me the link to Chem4Word Beta Version 3.1.

I have drawn the following structure:

I would like to draw a bond from the R4 “atom” to the center of the six-membered ring, to indicate that the R4 group could be placed in any position on the ring (Markush bond?). When I try to do this, Chem4Word places a methyl group at the end of the bond in the center of the six-membered ring. Can Chem4Word draw a bond without placing an atom at the end of the bond? Alternatively, can Chem4Word remove the display of terminal carbon atoms?
I would appreciate any information you could give me. Thank you.
Suzanne R. Harvey

Is your feature request related to a problem? Please describe.*

A clear and concise description [in English] of what the problem is. Ex. I'm always frustrated when [...]

Describe the solution you'd likeI would like to be able to draw a bond from an atom with no atom at the other end of the bond.

A clear and concise description [in English] of what you want to happen.

Describe alternatives you've consideredI have drawn most of the structure in Chem4Word, used the Snipping Tool to move it into another Word document and then draw the one line (bond) I need between the R group and the center of the ring.

A clear and concise description [in English] of any alternative solutions or features you've considered. If Chem4Word could turn off the display of terminal carbons, that would solve my problem.
