Bug #6829: Failure using Win32ole (happens in 1.8.7 and 1.9

• Status: Rejected
• Assignee: suke (Masaki Suketa)
• Target version: -
• ruby -v: 1.9.1 and 1.8.7

[mvanduyn (Mitch VanDuyn)]

The following code:

require 'rubygems'
require 'win32ole'
pdk = WIN32OLE.new("StampsDotCom.PDK5")
internet_postage = pdk.InternetPostage3
print_job = pdk.CreatePrintJob5
print_job.MailClass = 0 # first class
print_job.MailpieceFormFactor = 1 # envelope
print_job.MediaID = 2 ##10 envelope
print_job.PrinterName = "\\stamps1\Dev1"
print_job.MailpieceWeight = 1
print_job.AddRecipient("Stamps.com\r\n3420 Ocean Park Blvd Ste 1040\r\nSanta Monica, CA 90405")
internet_postage.PrintPostage("Stamps.com\r\n3420 Ocean Park Blvd Ste 1040\r\nSanta Monica, CA 90405") # this call works
internet_postage.PrintPostageEx(1, print_job) # this call fails

when run IRB causes the below error.

To fully reproduce this problem you will have to load stamps.com exe which is available from stamps.com (although you will have to get a trial account to get the exe, I can store the exe if needed, but its too large to upload here.

This code is from the stamps.com documentation, and is very similar to other code I have run in .NET, so I am sure it is correct.

A couple of notes:

1. The last 2 lines above have very similar functions. The second to last line executes perfectly, but the last line causes the failure. So this demonstrates that the basic com communication is working fine.

2. The last line is a bit different because it is being passed back an number (fine) PLUS a pointer to an object that is coming from the com object. Could this be the problem?

There is the dump!

can you try Ruby 1.9.3 and see if it reproduces?

I don't have Stamps software installed or a Stamps printer to test, neither I think the extension maintainer (suke) will do.

If we can reproduce this issue with simple WIN32OLE (no depending on Stamps installed) it will be great.

[suke (Masaki Suketa)]

Thank you for your reporting.
I'm not sure, but maybe you must specify variant type information
of arguments when you call PrintPostageEx.
I'd like to know what variant type of arguments is needed
to call PrintPostageEx.
What is the result of the following code in Ruby 1.9?

method = internet_postage.ole_method("PrintPostageEx")
method.params.each do |param|
puts param.name + ":" + param.ole_type_detail.join(',')
end

Best Regards,
Masaki Suketa

[mvanduyn (Mitch VanDuyn)]

Thanks for looking into this.

Here is what I get.

irb(main):005:0> method = internet_postage.ole_method("PrintPostageEx")
RuntimeError: failed to GetTypeInfo
HRESULT error code:0x80029c4a
Error loading type library/DLL.
from (irb):5:in ole_method' from (irb):5 from C:/Ruby193/bin/irb:12:in '
irb(main):006:0>

I tried the same thing on other things and the result is the same i.e. pdk.ole_method("InternetPostage3") raises the same error.

Could the following note from the stamps.com documentation have anything to do with it?

SMUI.TLB (Type-Library File) - The SDK provides Stamps.com client functionality in the form of an ActiveX object (SMUI.DLL). Although any COM-compatible language can access it, some languages, such as Visual Basic (when using early binding) and Visual C++, will require the type-library file in order to access them. Have attached this file in case it is of any help.

I have also attached the DLL in case that is of any help.

[suke (Masaki Suketa)]

Thank you for your reporting of the result and more information.

Could you try the following script using Ruby 1.9?

tlib = WIN32OLE_TYPELIB.new("(The folder of SMUI.TLIB)\SMUI.TLIB")
(or tlib = WIN32OLE_TYPELIB.new("(The folder of SMUI.DLL)\SMUI.DLL") )
method = tlib.ole_types.map{|t|
t.ole_methods
}.flatten.find{|m|
/PrintPostageEx/i =~ m.name
}
method.params.each do |param|
puts param.name + ":" + param.ole_type_detail.join(',')
end

And can you call PrintPostageEx from VBScript(neither VB nor VB.NET)?
If you can't call PrintPostageEx from VBScript, then you can't
call PrintPostageEx from Win32OLE.
Win32OLE supports only late binding, not early binding.

Masaki Suketa
