boolstatus in SW VB

if i record a VB macro in SW2007 and view it afterwards, there is always
lines who start with the word "boolstatus". what is this variable used for?

for example:

boolstatus = Part.Extension.SelectByID2("Point2@3DSketch1",
"EXTSKETCHPOINT", 0.01523113840303, 0.01784208683388, 0.00822428053602,
False, 0, Nothing, 0)

 

This is why I keep harping on people to get at least a little VB
literate before making macros.

In this case, "boolstatus" is a boolean variable. The variable is
declared earlier in the macro by this line:
Dim boolstatus As Boolean

The function "SelectByID2" returns a TRUE or FALSE and places it in the
variable "boolstatus" to indicate whether the command was completed
successfully.

If you're going to try to manipulate selections in a macro, you have
some studying to do. You will need to learn how the Selection Manager
object works and how to retrieve selections.

 

The function "SelectByID2" returns a TRUE or FALSE and places it in the

What I didn't understand is which part of the code is using this TRUE/FALSE
value in the code.
I mean: O.K. - boolstatus has now a value of TRUE. but which part of the
code after this decleration by SelectByID2 uses this value further? what is
the purpose of giving a variable a value if no command uses it's value
afterwards?

That's exactly what i'm trying to do:
I've got some previuos knowladge of the Basic programming language (not VB)
and i'm using the book "Automating SolidWorks 2006 using Macros" by Mike
Spens to try and teach myself the principals of macro programming in SW.
However, not every point is explained in that book or even in SW API help.
so as last resort i turned to this NG.

 

So now we're a last resort! I see how it is!

You don't need to use the "boolstatus" for anything. If you don't need
it, you can ignore it. In fact, you could also run the SelectByID2 as
a Sub instead of a Function (possible for all VB functions), and not
use a return variable like boolstatus. (Sub = no return variable,
Function = uses return variable)

The return variable ("Boolstatus", but could be ANY boolean variable
you choose) is simply used a flag so that the program can check if the
function completed its task successfully. For instance, you may
execute the function and then have an IF-THEN statement to check
boolstatus and perform actions accordingly.

 

O.K. now i understand - thanks for the explanation! unfortunatly the
transition from the '80 Basic language into VB is rather hard for me so
these things are not obvious to me........
