Good morning, good evening, and Good night to you all.
I have just started to write MapBasic programs and am finding it very
challenging.
I have a scenario where i have a table that has a specific Brush and Pen
styles set to it. From this layer i want to select particular polygons
using a select query, and then change the polygon style to something
different. I want to automate this process so because it is a weekly one,
and i have to select a lot of different polygons and change their styles.
So far i have:
* opened the table,
* selected the polygons from their field and their text description,
* mapped the query and made it editable.
* All the polygons come up selected.
Now i just need the final process, to change the style (Brush, and Pen) and
then commit the table.
I have been playing around with the following code.
.............After the query
Map From Selection
Set Map Layer 1 Editable On
Dim WRC_b As Brush
dim selectionobj as object
WRC_b = ObjectInfo(Selectionobj,OBJ_INFO_BRUSH )
Alter Object Selectionobj
Info OBJ_INFO_BRUSH, MakeBrush(2, 32896, 16777215)
This compiles but doesnt work. It says "Can not use an unitialized object
variable in and expression"
I dont know if this is the correct way to change the region style, CAN
ANYONE POINT ME IN THE RIGHT DIRECTION.
Thanks heaps.
