Keith, I've begon the journey, just need some more road maps.
The text is backward on a mirror/delete but the reactor is firing as needed. (because of "MIRRTEXT")
The reactor doesn't fire on a mirror/ w/out delete.
TODO:
-capture the mirrored item when not deleting the original
-save and set "MIRRTEXT" to 1 before the reactor
-restore "MIRRTEXT" to original value after reactor
Where should I search for these kinds of problems?
What should I use for my help file?
Ok, I need to find out something .....
Do these blocks contain attributes? If they do, then the mirroring of the blocks (with mirrtext on) will produce acceptable results except the block will be mirrored, the text should not be, but when mirroring with delete, the blocks mirrored are reset to a positive scale factor ... that is the abs function returning the absolute value of the scale factor and reapplying it. However this does not qualify as a mirror and as such mirrtext does not apply, AND the resulting text WILL be backward.
To account for this, you will need to obtain the attributes of those blocks and change each one of them to not be displayed mirrored. Plain text embedded in blocks will always be shown in the defined fashion, in relation to the rotation and scale of the block, and as such is unaffected by mirrtext.
As I posted before, what you can do is create a "BeginCommand" reactor that will grab the last entity in the drawing, then using it as the base and all objects created after this one are new, and as such should be gathered into the selection set. This selection set can then be acted upon by the EndCommand reactor when the mirror command ends.
As far as the help file, I am not following your request here, but just in case I misunderstood I will give you two options ....
For VB(a) help simply use the help files associated with the VBAIDE interface and the MS VBA help files (accessable from the help menu in the VBAIDE) Also look at the object reference window and you will get a better understanding of objects and their associated proerties and methods.
Now if you were looking for a help compiler to build a help file for your application, there are a few out there that are free and I know Hendie has used one, you might see if he can point you in the right direction.
