Accessing COM interfaces in AIR

Is there a way to access Windows COM interfaces through adobe air? I'm working on an app where I need to be able to interact with another Windows program. I want to use methods like WScript.CreateObject() in my code, and I can do this when I run the javascript files from the command line with WSH (i.e. cscript filename.js), but not through air. The error I get is "Can't find variable: WScript". Is there any way to access COM interfaces, whether through WScript methods or something else?

any idea how to do this in AIR 2? Looking at the documentation, I see that you can run executable files using the NativeProcess class, so I guess could execute something like "cscript filename.js" and then "filename.js" could contain WScript methods. But does anyone know of a way I can take advantage of COM interfaces more directly using AIR 2?

COM Interface DLL Working in Windows XP Not working in Windows 7 virtuallly running WIN XP mode

Hi,
I am Prasad, I want one clarification on Win7 64 bit inside we are running Windows XP in virtual mode. I am facing the problem in COM interface DLL which will do remote access to server & Core banking , Client & core banking.
Now the client (vendor) running the application in Win7 64 bit of Windows XP application by making XP environment virtually in Win 7 64 bit OS.
Here entire application is working fine apart from COM interface DLL (Even though we are exporting as .msi package and we are installing in Virtual Xp machine tried with both versions of 1.0 and 1.5)
Can anyone please let me know is there any possibility to overcome this situation without upgrade the entire product to Win 7 for time being?
Thanks In Advance..

Based on my knowledge, a 32 bits components can run on a 32 bit virtual machine. Do you get any error message?

SAP XI and COM interface

The Import / Export Service has been developed by 3rd Party to allow you to programmatically load information into the 3rd Party Command Centre System. The service can be used to initialise new installations, and to synchronise data in an on-going basis with other applications within your organisation. The Import / Export Service is a licensable feature. Therefore, for this feature to work, your site must have the Import option turned on in their licence file.
The service consists of a Microsoft Component Object Model (COM) Automation interface, and a set of import / export plus data translation scripts. Data is imported into the system using the Extensible Markup Language (XML). While this is the sole format the system uses for data imports, translation scripts are provided to convert from comma or other delimited file formats, to XML.
Data may be loaded into or extracted from the 3rd Party Command Centre System in an on-line real time manner, or in a batch oriented approach. The method that is most appropriate to you will depend on your specific business requirements. The on-line method is appropriate if you require data to be immediately updated in 3rd party Command Centre after being keyed by an operator into one of your existing applications, or where an external application requires immediate access to data held in 3rd Party Command Centre. This method is provided via a COM Automation interface that can be called by any COM compatible programming language, (e.g. VB, Delphi, JScript). The batch approach also uses the Automation interface, but information is passed to or from 3rd Party Command Centre in one or more data files rather than directly through the programming interface. This approach can either be initiated by calling the COM interface directly, or by setting up a scheduled task that looks for, and processes, new files.
My question is can I directly communicate with this COM interface with the existing adapters of SAP XI. I had initially thought of file adapetr to put the XML file in the FTP location from where this COM interface will poll and pick the file but in a real time scenario can we go for this approach. The other option is to publish this COM interface as a webservice but not sure how much rework is required to make this COM Service webservice enabled.
Apart from this can you suggest any other approach which we can work out.
Thanks in advance
Ravijeet

Hi Ravijeet !
You could develop a Java Proxy client that uses the COM objects to extract data and send them directly to XI (http://research.microsoft.com/~chadv/java_com2.htm)
Or you could develop a proxy application in VB or any other tool and do the COM calls and then connect to XI via HTTP, RFC (e.g. SAP .NET Connector) without creating any file in any file system.

Matias.

How come my macbook air has so little space. I deleted everything that I don't need and everything that has the most space I'm told NOT to delete. Everything I find is in either KB or very low MB.

Your Solid State Drive and having enough space inside your Macbook Air & Pro
Solid State Drive usage premise, or the “more space / upgrade SSD” question
There have been questions posed and positions taken by many people who are trying to use their Macbook Air or Pro’s solid state drive (SSD) as a mass media storage device, for either pictures, videos, massive music collections or all three combined; but this should not be the working premise of a ‘limited’ SSD and its use.
In which, it’s the case of those users with either 128GB, 256GB, or even 512GB of internal SSD space, that have or are running “out of space”, that questions are raised. The immediate premise of some users can sometimes be “(how to / if) upgrading my SSD” when in fact in nearly all instances another approach is the logical and sensible one that needs to be looked into and exercised.
Any Macbook containing a SSD should be idealized as a ‘working platform’ notebook containing all your applications, documents, and weekly or bi-weekly necessary files. All collections of media files such as pictures, music, and videos, unless directly needed should be kept off the notebook and on an external hard drive or likewise. While the ‘working platform’ premise is also the case with larger internal conventional hard drives of 1TB+, its implementation isn't as critical except in terms of data protection.
Realistically, you should at most coordinate roughly 20 to 25% of your total SSD space to all audio-video personal use media (picture / music / video collections), leaving the remaining amount on an external HD.
Nobody should consider any notebook a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device; and in the case of a SSD, this is more important for purposes of having sufficient working space on the SSD and reducing SSD ‘bloat’ in which cases someone is wrongly attempting to use the SSD space as a large media storage nexus.
The rare exception to the collective usage and premise of SSD use in which a much larger SSD is truly needed are for those in video and photography professions that require both the extremely fast speeds of the SSD and the onboard storage for large and or many video and photography files. However this also falls under the premise of a ‘working platform’ for such peoples rather than the intent of many who are using the SSD as passive and static data storage for media files very infrequently needed or accessed.
All on-notebook data collections should be logically approached as to necessity, and evaluated as to whether it is active or passive data that likely doesn’t need to be on the notebook, allocations of space-percentages to as-needed work and use, apportioning space for your entertainment media, and questioning whether it should it be on the notebook for more than short-term consumption.
Considerations should be made in the mind of any user in differentiating the necessary system data (System hub) comprising the Mac OSX, applications, necessary documents that both must and should be on your internal SSD, and that of the users personal data (Data hub) comprising created files, pictures, music, videos, PDF files, data created or being created and otherwise, that likely unless being used soon or often should be parked on an external hard drive for consumption, or temporarily loading onto the internal SSD.
You both can and should purchase whichever SSD size you need or see fit, but even in the case of the largest of SSD, unless use-considerations are made, and SSD spaces are allocated as should be the case indicated above, one can easily and immediately run into this quandary of “needing more internal SSD space”, in which instance a different approach in usage must then be implemented.
However it is almost always the case, that such large media files are wanted to be stored internally rather than actually needed, in which case the external HD is both prudent as well as necessary. Additionally costs per MB are infinitely less on an external HD than an internal SSD in any consideration of data expansion needs.
A Professional Example
In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.
You should also never be put in the position of considering “deleting things” on your Macbook SSD in order to ‘make space’. This is especially what your external HD is for.
Professionals who create and import very large amounts of data have almost no change in the available space on their notebooks internal SSD because they are constantly archiving data to arrays of external or networked HD.
Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your Macbook has a SSD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your notebook to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
Slim USB3 1TB external hard drive
External Hard Drives
External hard drives are both extremely cheap and regardless of the size of your internal SSD (or even internal hard drive if the case), you need an external hard drive with your SSD equipped Macbook for several reasons:
1. Data backup and protection.
2. Redundancy for important data.
3. Necessitated ideal space for large media files for collections of pictures, videos, and music etc.
While ever changing in price, typical portable 2.5” external hard drives in USB3 run roughly $65 for 1TB or $120 for 2TB small portable USB3 hard drives. Such drives range in thickness between 5mm and 15mm, with recent improvements in storage of 500GB drives in 5mm profiles.
There is almost no premise in which a small 12mm thick 1 Terabyte USB hard drive cannot be taken along with any Macbook as an external large storage extension inside any Macbook carry case or pouch. Typically such external HD profiles are not much bigger than a deck of cards.
External hard drives are a foregone necessity for purchase with any Macbook for at the very least Time Machine backups, data redundancies, and ideally for large media storage.

Cannot downcast IITWindow to IITBrowserWindow in iTunes COM interface.

Actually, what I'd really like is the ability to highlight a playlist, or an artist, or an album, or a bunch of tracks and use right-click to send the information to another application. But as that isn't an option, I've started looking at the iTunes COM interface.
The code I'm trying to run, gets an IITWindowCollection using LiTunes:Windows() and then iterates though these. When it finds either a BrowserWindow, or a PlaylistWindow, I want to do more processing. But I'm unable to downcast the IITWindow object to an IITBrowserWindow.
Here's a snippet of what I'm trying to do:
IITWindowCollection* iIWindowCollection;
long lCount;
hRes = iITunes->get_Windows(&iIWindowCollection);
hRes = iIWindowCollection->get_Count(&lCount);
IITWindow *iITWindow;
ITWindowKind iTWindowKind;
BSTR bstrName;
IITBrowserWindow *iITBrowserWindow;
IITTrackCollection *iITTrackCollection;
for (long i = 1; i <= lCount; i++) {
hRes = iIWindowCollection->get_Item(i, &iITWindow);
hRes = iITWindow->get_Name(&bstrName);
hRes = iITWindow->get_Kind(&iTWindowKind);
switch (iTWindowKind) {
case ITWindowKindBrowser:
// At this point I need to refer to the object as iITBrowserWindow, not iITWindow.
iITBrowserWindow = dynamic_cast<IITBrowserWindow *>(iITWindow);
if (iITBrowserWindow) {
hRes = iITBrowserWindow->get_SelectedTracks(&iITTrackCollection);
break;
case ITWindowKindPlaylist:
break;
When I run it, I get an exception on the dynamic_cast.
What am I doing wrong here, as I can't see why this shouldn't work.
Or is my lack of C++ knowledge that obvious. <GRIN>.
Cheers.

Ha. I was partly right with my comment about lack of C++ knowledge. It turned out to be a lack of knowledge on how Windows COM works.
In case anyone else runs into this, and finds this thread, (Yeah, right. LOL) here's the answer.
You can't just "cast" from one object to another. You have to use the IUnknown::QueryInterface function to get the pointer to the new Object.
Easy when you know how, not !!!!!
Now onto other questions about how to access parts of the UI through this interface.
Cheers.

BUG: iTunes truncates lyrics when using COM Interface

Hi!
I am using iTunes 6.0.4.2 for Windows (Latest Version at the moment), running under Windows 2000, both in english. I wrote an application that accesses iTunes using the COM Interface, and i am using the latest type library (1.7).
Everything works fine, except for one odd thing: Lyrics.
When i get Lyrics from a track, they get truncated - one char for each line break.
Tried the following: Added the following lyrics to a Track:
12345678901234567890
Works fine, when i get the lyrics, i get 20 chars and they are intact.
Now, i change the Lyrics:
1234567890
1234567890
When i now get the lyrics, i only get a string with 21 characters - the resulting string is
1234567890<#13><#10>123456789
(<#13><#10> are representing the ascii chars 13 and 10, not the actual strings <#13><#10>!)
For every line break I add, i lose a char. With this Lyrics:
1234567890
1234567890
1234567890
1234567890
the result is:
1234567890
1234567890
1234567890
1234567
iTunes seems to have a problem with line breaks, as they are represented by 2 chars (CR+LF, Ascii 13+10) in Windows rather than 1 char (CR, Ascii 13) in UNIX.
This seems to be a Bug in iTunes. I tried the following JScript Code:
var iTunesApp = WScript.CreateObject("iTunes.Application");
var currTrack = iTunesApp.CurrentTrack;
var Lyrics = currTrack.Lyrics;
WScript.Echo("Current Track: " + currTrack.Name);
WScript.Echo(Lyrics);
and this gives me:
Microsoft (R) Windows Script Host Version 5.6
Copyright (C) Microsoft Corporation 1996-2001. All rights reserved.
1234567890
123456789
As you see, it truncated the last 0.
I am doing my real programming in Borland Delphi 7 Personal Edition, and it happens there as well - for every line break, I lose 1 Character.
The display in iTunes Lyrics-Tab is fine and not truncated, so it just seems to be a bug in the COM-Interface. Not sure where to report them, so i'll just post here. maybe someone knows a remedy?
Here are some Screenshots:

http://img239.imageshack.us/my.php?image=version7fo.jpg
Windows 2000 iTunes 6.0.4.2, iTunes Type Library 1.7

Edit: I just tried a german Version of iTunes 6.0.4.2 on an english Windows 2003 Server with a different Track - same problem here.
I then downgraded to iTunes 6.0.1.3 on the same machine - same: 1 lost char for each line break. It does not matter if I add "fresh" lyrics using iTunes 6.0.1.3 or if I query the ones made in 6.0.4.2.
I don't have iTunes 5.0.1 anymore, but I will try to get it to try with this version.

Problem accessing local interface methods

Hi all,
I have problems accessing local interfaces of entity beans in OC4J.
My application consists of a session bean as a facade for two local entity beans.
Everytime I try to execute methods on the local interfaces for the entity beans, I receive an exception: "java.lang.InternalError: Illegal removing from cache".
When debugging the application everything seems to be fine until the method calls on the local interfaces (lookups, create methods etc OK). I can even see that the local interface method is acually executed when performing a System.out...! But the method doesn't return to the client (session bean). Instead I revieve the exception above.
I found a similar problem on the orion mail archive (http://www.mail-archive.com/[email protected]/msg17754.html). But there they seem to have problem with removing beans. For me, removing beans works fine too.
Any suggestions would be appreciated.

Error "cannot access com.sun.java..."

edit i mistyped in the topic name, i mean to say "com.sun.j3d..."
I've set myself up using JCreator, installed j3d, j2sdk, and jdk. Tried a few test programs to make sure everything was working (a basic hello world and my chess game i created my junior year in highschool). It was all running fine.
So i started reading into j3d tutorials, and came across the HelloUniverse sample program. I slapped the code in and compiled it, only to be met with:
"cannot access com.sun.j3d.utils.applet.MainFrame".
I commented out the import line that included this, compiled, and it gave me another message complaining about the same thing, only this time ending in:
"...geometry.ColorCube"
Obviously, its just running down the line with all of the j3d imports, so i ran through and reinstalled all my j3d files; still didnt work. I can't figure out what's wrong with it. Please help.

What can I change to gain access to my work vpn. I can access with my MacBook Air and other routers. Can use my ipad and this time capsule to successfully access the VPN.

You need to give us a lot more info.
I presume the MBA and the TC are the combo that doesn't work, although you don't clearly state that.
If the ipad and TC work.. are you sure the ipad is connected via the TC and not 3G network?
If it is then the TC itself is fine and the issue might be setup on the MBA.. although if the MBA works with other routers.. that rather confuses the matter.
You need to actually tell us how the TC is setup in the network. What kind of broadband modem you have and what kind of vpn you are using.

How to make in/out Port vis work with COM interface under different windows versions?

Hello!
I know that the accessHW is necessary for it, so I downlaoded the
this file from the homepage of NI, but there are always some problems
with it.
My program should get the the voltage impulse between
the pins DTR and RTS of a COM interface. After
I installed accessHW under winNT, the voltage between them changed
automatically from 0 mV to about 24 mV , and program
worked well . But this way does not work under Win98 and Win2000,
and this voltage is always 0 so that the device can not make any voltage
impulse.
Could someone give me a software solution for it? Thanks!
P.S:The version of the labview I use is 6.1.
Le

You shouldn't depend on a voltage difference between the tow pins unless you need something like 24 volts and not 24 millvolts. All of the signal lines are referenced to ground and the signal lines usually swing between -3 to -12 and +3 to +12 volts. If you truly saw a 24 millivolt difference between two signal leads, then all that means is that they are both at the same logic state. A difference of 24 millivolts is not much and has to do with the UART in your computer and not accessHW I believe though maybe what happened is that the difference is 24mv when both are logic "1" and less when logic "0" or vice versa. If your device requires power from the serial port, then what you'll have to do is control the signal lines in your program and I
would recomend VISA to do that instead of inport/outport. And check the voltage requirements of your device. If this is a device you designed, it should be designed for the lower voltages on new pc's and laptops. In other words, I would depend on 3 volt signals instead of 12. There are numerous references to either RS-232 or EIA-232 on the web. I think a review of the electrical specifications is needed.

How is it possible to use a COM interface in the teststand?

Hi,
we have developed some small aplications that control our devices and we are planning to make a com interface for these applications?
We would like to control this com (NOT the serial interface) interface from teststand. We do not have Labview.
Is this possible and if yyes can you point me where I can read the procedure?
Or if it is not described can you briefly describe it?
Is there any other more suited options of controlling an application from Teststand? The answer to this question for us is extremly important because we would like to develope as little as possible beside the application and use the Teststand ablities to the maximum.
Our application is written in C++ with VC++ .net 2005
I already checked out the manuals and the source code but I didn't find any examples most of them use dll-s and ActiveX.
Thank you fro your help and time,

Try adding p13n_system.jar. It contains the exception class you need and should
