Topic: (vla-ismergedcell) 7 arguments?

[roy_043]

The function (vla-ismergedcell) has 7 arguments:

Code: [Select]

(vla-ismergedcell tableObject row col minRow maxRow minCol maxCol)Can anybody explain this?

I would understand this:

Code: [Select]

(vla-ismergedcell tableObject row col)Or this:

Code: [Select]

(vla-ismergedcell tableObject minRow maxRow minCol maxCol)

[MP]

Ima gonna guess it's to be interpretted as ... "for the cell at row and col, return true if it is a merged cell of the range defined by minRow, minCol ...".

[Lee Mac]

IMO the function would be better if minRow / maxRow / minCol / maxCol were output parameters returning the range of cells that are merged for the supplied cell at Row / Col.

[MP]

totally agree, they was drinking funny water the day they penned that function signature

I've never executed said method, and there's scant documentation and no example (AutoCAD 2010 anyway). Maybe that's exactly the way it works Lee.

I haven't tried it either; the documentation doesn't specify the parameters as output and the function has a Boolean return value, but I should imagine this method is similar to the HitTest method.

[Lee Mac]

Tested and confirmed. 

Revised Function Documentation:

Code - Auto/Visual Lisp: [Select]

1. (vla-IsMergedCell <TableObject> <row> <col> <minRow> <maxRow> <minCol> <maxCol>)

Arguments:

<TableObject>  -  VLA Table Object

<row> / <col>  -  The index of the cell to query

<minRow> / <maxRow> / <minCol> / <maxCol>  -  [output]  The range of merged cells.

Returns:

Type: Boolean

:vlax-true   -  cell at <row> / <col> is part of a merged range: (<minRow>, <maxRow> ; <minCol>,<maxCol>)

:vlax-false  -  cell at <row> / <col> is not part of a merged range

Example



[ Note that row / col indexes are zero-based ]

Code: [Select]

Command: (setq obj (vlax-ename->vla-object (car (entsel))))

Select object: #<VLA-OBJECT IAcadTable 0e8f951c>

Command: (vla-ismergedcell obj 2 0 'rmin 'rmax 'cmin 'cmax)
:vlax-true

Command: !rmin
2

Command: !rmax
3

Command: !cmin
0

Command: !cmax
1

Good work Lee.

Good work Lee.

Cheers dude

Make sure you PM a link of your post to Se7en so that it may be added to the recent LISP function Help feature.

Thank you Lee for clearing that up. Where would we be without you!

In BC this function is currently not compatible:
for the min and max arguments you can use any number (even a real) but NOT a quoted variable.

I did search theswamp for this (of course ) and found this bit of code:

Code: [Select]

(vla-ismergedcell tab lig col 0 0 0 0)

As you can guess BC has no problem with this. But how does AC cope with those four zeros?

You're very welcome Roy, thanks!

AC returns the boolean result without error.

Thanks again Lee.
