Hello
i am using ole automation to drive some of my processes. the following
code would run properly in other languages like vbscript. but it fails
only in ruby
application = WIN32OLE.new("Broker.Application")


analysis=application.analysis()

analysis.Filter(0, "market") = 3 # use nasdaq only << ruby
does not allow setting values like this. it errors syntax error,
unexpected '=', expecting $end. however this assignmetn is valid in
vbscript for the same object. is there any other way of doing it.

I'm not a vbscript guy, but did you try:

myvar = analysis.Filter(0, "market")
myvar = 3

?

Nope. it does not work
b=analysis.Filter(0, "market") #= 3 # use nasdaq only
b=3
It does not change anything at all.
However if i ran a similar code in vbscript, it does the magic.

set application = CreateObject("Broker.Application")
application.visible=1
set analysis=application.analysis()
analysis.Filter( 0, "market" ) = 3

so something is wrong with the way ruby does automation.

Maybe the library does not know about the default property,
which VB uses...

So assuming that you're assigning the .Value property, try

analysis.Filter(0, "market").Value = 3

in ruby.

I wonder ... does

p analysis.Filter(0, "market").methods

return any useful information?

Ruby does not support the following syntax, so Win32OLE
does not support.
> analysis.Filter( 0, "market" ) = 3

Instead, does the following script work?

analysis.setproperty('Filter', 0, "market", 3)

it configures one of the windows within the app.

Because I'm a maintainor of Win32OLE. :-)
To support property setting with argument like Filter,
WIN32OLE#setproperty method is provided.
