Re: ActiveX problems with 3.0.F.2 (fwd)
Forte has very specific requirements for ActiveX controls. We found out the
hard way that Forte does not support the use of all ActiveX controls.
Here is some information I received from Mark Cooper at Forte:
With a bit more digging I found that ActiveX controls are required to adhere
to two restrictions in the Forte environment. ActiveX controls are required
to provide a single interface (and cannot include irrelevant nested
interfaces) and must implement Apartment model threading (technote 11344).
You can use the OLE-Com Object Viewer to determine whether a control
fulfills both of these requirements.
Hope this helps. As I understand it, a future release (3G or 4???) will have
better support of ActiveX controls. But in the mean time you are stuck to
these limitations.

ActiveX problems with 3.0.F.2 (fwd)
This is the message I sent to tech support. Has anyone else seen this
type of thing? Any suggestions (even half-baked) would be appreciated.

Subject: ActiveX problems
Product: Forte
Version of Forte: 3.0.F.2
Server OS: HPUX
Client OS: NT/Win 95
DBMS: Oracle
Reproducible(?): Yes
Brief description of issue:
I have experienced problems using ActiveX controls. I have tried several
controls, including:
o Microsoft Forms 2.0 SpinButton
o Microsoft Forms 2.0 CheckBox
o Microsoft Forms 2.0 EditBox
o AddSoft Gantt/OCX
o Sheridan MonthView
o Sheridan DayView
o Sheridan DateCombo
o Microsoft Calendar Control
(specifically mentioned in a Forte technote)
I have experienced problems with all of these controls. With the Sheridan
DateCombo, the Forte environment crashes when I attempt to drop the
control into a form using the "Insert Control..." button. Before the
environment crashes, I get a series of informational and error dialog
boxes as follows:
o error: unexpected exception -10737415717
o error: The Error Manager stack is empty (repeated 3 times)
o information: the workspace is now read-only because the
repository is disabled.
o error: Exception escaped from terminating task CW.Display
o ERROR: TMgr.Terminate: fatal error terminated partition
With all the other controls I tried, the ActiveX support appears to work
properly until I attempt to bind an instance of the olegen-generated
class to the control itself in the window's Init() method:
--- MyWindowClass.Init() ----
super.Init();
myActiveXControl = new();
After this has been done, the Forte environment may "hang" when I interact
with the control at run-time. For example, each time a generate a mouse
event inside the control, I risk hanging the Forte environment. I might
be able to interact with the control 50 times before the environment
hangs, or it might hang after a single mouse click. Until the crash/hang
occurs, the ActiveX support appears to work properly: I am able to trap
mouse events, and interact with the control using the provided interface.
Any help or advice you can offer would be appreciated. I would be happy
to provide any additional information you may require.
-- Adam McKeeI don’t recall any problems importing to “selected item’ which I always use so I define where it goes and what it’s called.
Do you have Aperture’s Activity Window open so you can see where it is hanging up? Is it just busy generating Previews etc.? I know it sounds more serious than just ‘busy’ but would be interesting to know what it’s doing then.
After these problems, assuming that previews and thumbnails are generated correctly, it may be a good precaution to restart Aperture while holding down the OPTION and COMMAND keys so you can Repair Permissions or Repair the database. Even rebuilding the database is fairly quick if those first two options are ineffective. -
Events problem with (Java and ActiveX)
Hi,
I use an ActiveX component with Java and i've got a problem with events.
Java classes were generated with Bridge2Java (IBM).
In order to manage events I added a listener in my application :
javaMyActiveX = new MyActiveX();
javaMyActiveX.add_DMyActiveXEventsListener(new _DMyActiveXEventsAdapter());
I also added a constructor in the _DMyActiveXEventsAdapter class and I fill the body of methods.
The ActiveX generates two types of events :
- The ones are directly generated by methods.
- The others are generated by a thread.
With MS Products (VB, Visual C++, Visual J++), I catch all events.
With java (jdk 1.4), I catch only events generated by methods.
Can anyone help me.I'm not 100% sure, but the last time I used that bridge, it only worked if you ran your Java app within a Microsoft VM.

Problems with ActiveX Callbacks in LabVIEW 7
Have encountered an interesting problem with ActiveX "Reg Event Callback" in LV7 (WinXP):
In a nutshell, when a lot of events fire in rapid succession, the user-interface locks up.
The events still fire, and the front panel controls update, but the front panel will not respond to clicks. Interestingly, if the block diagram is open, you can stop it and turn on execution highlighting, etc...
- I've discovered that the problem we're encountering is related to multiple events firing before the (reentrant) callback VI has finished executing from the 1st event.
- by watching the Performance data in task manager, and tracking the # of handles used by LabVIEW, I find that when this happens, the # of handles increases, b
ut never decreases until you stop the VI
- I would expect several (nearly) instantaneous events to launch multiple copies of that callback VI, and I can believe that would increase the # handles, but I would expect that LabVIEW would catchup shortly thereafter and the # handles would return to its starting count.
As an aside, using the old ActiveX event and callback method with the exact same version of the activeX control does not have this problem, events just queue up and then fire appropriately.
Anyone seen anything like this?
Anyone (NI guys) have any ideas?
Follow up question (NI guys): when will the support for the old ActiveX event stuff dry up?
Thanks in advance,
Ben

Meikle AutomationHi Ben,
The error message warns about the use of three ActiveX Event VIs that will no longer be supported in future versions of Labview. Following version 6 of Labview, the use of ActiveX Event VIs is shifting to the use of Register Event Callback VI instead. In looking at your screenshots, I did not see any use of the older ActiveX Event VIs. If possible, try attaching the actual VI to the post and I will take a look at that.
At least in terms of support, phone support currently exists for Labview 6 and 7. With the release of Labview 8, support for Labview 6 will slowly be phased out. In this case, phone support for the ActiveX Event VIs will no longer continue as they are no longer included in the versions of Labview for
which phone support is provided. However, Discussion Forums and web-based resources would be your best venue of support for those features.
I would strongly recommend that you migrate to replacing ActiveX Event VIs to using the Register Event Callback VI. The following is a KnowledgeBase article describing the transition of ActiveX in Labview:
Migrating from the ActiveX Event VIs to Using the Register Event Callback Node
Also, are you using the Automation Open/Close VIs? These two VIs will allow acquire/release informatio nof the ActiveX object. I have attached a couple example programs that are included in Labview to help demonstrate this concept.
Hope this helps!

Problems with ActiveX and an IRtrans-modul
Hello,
I have a problem with an IRtrans-USB-modul. This is a modul for learning or sending infrared commands.
The modul is connecting to the USB-port and supports ActiveX and .NET protocols.
I have registered the ocx-library with the command regsvr32 and in LabVIEW I have the selection for the ActiveX-class.
But when I use a method and will send or learn a command I get the
failure: Exception occured in Winsock, wrong protocol or connection
status for the prompted transaction or demand. Help path in
MSWNSK98.chm and context 1040006 in Unbenannt1.
With the supplied software from the manufactor the modul is working fine.
Somebody is using this as well? Or somebody could help me with this problem?Hello Tweety,
I've installed the software for the IRtrans module. Unfortunately, I can't start a server, because for this I have to connect this module.
If You can select the methods of the IRtrans objects in LabVIEW, the activex connection should be OK. Make sure, that You use the right parameters and the right data types.
Here is a link to the software, I've installed. Do You have the same Version?

Problems with the ActiveX bridge for Java beans when using third-party .jar
I encountered the following problem when using the ActiveX bridge for a java bean:
I am using JDK 1.4.2_09 and MS Visual Basic 6.0 (SP6). I wrote a java bean called ProcessViewer (my class ProcessViewer inherits from JComponent and implements the interfaces Serializable and AdjustmentListener) which I would like to use within a VB 6.0 application. I used the ActiveX bridge (packager.exe) to generate a DLL (ProcessViewer.dll) and registered it successfully. The java bean GUI-control works fine within my VB 6.0 application unless my java bean (ProcessViewer.jar) uses any third-party .jar files.
But when I tried to add a reference to some third-party class (com.sap.xxx.xxx....) I got some problems. I could solve the problem with packager.exe by setting the correct CLASSPATH. But at runtime my VB 6.0 application does not work. It crashes or it reports an error like this: "The control ... could not be loaded from axbridge.dll" (although I deployed my .jar file correctly to the directory C:\Programme\Java\j2re1.4.2_09\axbridge\bin and lib). Setting the CLASSPATH environment variable before calling my VB 6.0 application (exe) did not solve the problem.
How can I teach my VB 6.0 application (containing the Java bean ActiveX control) where to find the third-party .jar file? Copying the third-party .jar file to the JRE lib-folder or to the axbridge\lib folder did not solve the problem either.
I studied the documentation about the ActiveX bridge given at:
http://java.sun.com/j2se/1.4.2/docs/guide/beans/axbridge/developerguide/index.html
but I am missing informations on how the third-party .jar files can be found during runtime of the ActiveX container (e. g. a VB 6.0 application).See how to solve your problem with JNI:

I am having problems with my VB 6.0 program that uses a Java Activex Bridge. When I shut down my VB 6.0 application the service control manager logs a message in the event log that the program terminated unexpectedly.
I have done some analysis and I have realised that the service control manager outputs this message only when my VB application creates the Java activex object. It appears that for some reason the Java object does not destruct cleanly.
I have got 2 versions of Java plug-in 1.3.0 and 1.3.0_02. Only 1.3.0_02 is enabled. I am not sure whether are any known issues with the version of the plug-in I am using which causes this behaviour.
I will be grateful for any suggestion which would help me in resolving the above problem.Check the registry. The activeX has a CLSID, the CLSID points to a jar file (HKCR/CLSID/{$CLSID}) does this jar exist?
Does the beans.ocx used exist. Is it used in a plug-in that works (in the control panel there a Java Plug in for each version). -
Problems with automation open for activex control
Hi,
I want to open an ActiveX Control (.ocx-file) with the Automation Open function. This .ocx file was successfully registered by using regsvr32.
The VI is working fine after using Automation Open and all the contained classes are accessible.
However, after saving the VI and opening it again the error 2147221164 appears and the program failes - referencing the object new at the Automation Open functions solves the problem, but only till the next reopening of the VI.
Hope somebody has a solution for this "instability"...
Sorry for bothering and thanks for any help!!!Hi smercurio_fc,
originally i had a dll written in c++ which contained classes - i wrapped this in a activex control to have access via labview. Im calling the activex control with the automation open function in same VI in which i am also using property nodes and invoke nodes to have access to the classes and methods...
But as i told before, it happens that Automation Open fails, when starting the VI again after closing(saving), even so it was working perfectly fine before...
Thanks for your response... -
Problems with an ActiveX container with a Microsoft Web Explorer in a subpanel
I have an application with a subpanel.When I push a button I insert another VI in the subpanel. This VI has an ActiveX container with a Microsoft Web Explorer inside. The problem is that the first time I insert the VI all works, but the next time the VI is inserted the ActiveX container appears empty.
Could anybody help me? Thank you very much.Hi,
In the following two VIs ( uno.vi & dos.vi) I have tried to reproduce the problem you are facing. In my case eveything worked properly.
I used LV 7 & Internet Explorer 6.0.2800.1106 under Windows 2000
Try running the VIs I attach and check if the same thing goes on happening.

Strange problem with RDP and mouse, only solved after minimize/maximize
Good day,
We have this very annoying problem with a RDP Terminal Server. It is Windows Server 2008 R2 SP1.
This server has the Session Host role installed, with local RDP user licenses.
We only have this issue when running a certain application.
This application is called Rockwell FactoryTalk View and this in an application to display industrial processes.
It will take the Full Screen in a fixed resolution and will display buttons, objects, values... The application also uses Internet Explorer cache so I think it uses ActiveX, Flash or Java, I don't know.
What sometimes happens is this:
- The mouse point is able to move in the entire screen (good)
- The mouse button will only work in 1 certain area of the screen (which is a small rectangle)
- The mouse "hovering" above objects will also only highlight items that are in this rectangle
- The keyboard remains functional and with alt-tab other objects or other applications can get focus, but still no mouse clicking
The problem can be solved by:
- Minimizing the RDP window and maximizing it again
- Or: Sending a message to the session using task manager, after clicking "OK" on that message the problem is gone
Normally, about 5 users will have this application opened in their session, the "crash" is only effecting 1 session.
The problem seems to happen randomly and we don't know if we should point to the FactoryTalk application, or to Terminal Services/RDP. The end users have no rights to minimize/maximize, this is not the solution.
Is it possible to have any input on this please?
Thank you.Hi,
Thank you for posting in Windows Server Forum.
Firstly please check with the application support team whether the application is fully supported by Windows Server 2008 R2 in remote session. In addition, suggest you to update the client RDP version to RDP 8.1 and check the result for better feature and functionality.
Apart from this, there is Hotfix for the issue. Please download, install and check the result.
Cause:
The issue occurs because the remote desktop ActiveX object does not deactivate the focus of the remote desktop session when the focus is lost. Because the focus is still activated, the remote desktop ActiveX object cannot set the focus of the remote desktop
session again when you change the focus back to the session.
A remote desktop session does not respond to keyboard input or mouse input after it loses the focus in Windows 7 or in Windows Server 2008 R2

Problem with SLD and Creation of JCo
Hello everyone!
I have a problem with the SLD and the Creation of JCo on the Portal, in trying to create the JCo always tells me that the name used there in the SLD, being that the facility is new.
Who performs the installation, set in the SLD the ECC 6 PRD, delete it to see if I could create a JCo but still the error again when creating the ECC 6 PRD in the SLD I said that already exists and can not create it.
I found a forum which recommended re-import the cimsap .... .... zip and zip CR_Content which would clean everything, I managed to import the zip cimsap ... but in trying to raise CR_Content gives me the following message "All incremental updates of the selected aggregate import for export SAP_CR line have already been loaded before. You require a newer import to update your current content SAP_CR version 4.11." .
I recommend, do the installation again, reload the cimsap.zip and CR_Content.zip a copy homogeneous.
from already thank you very much

Now I need to create the systems and "JCo" necessary to enable them to implement the "ESS", but errors are presented above.
Some days ago I managed to update the CR_Content, which allowed me to create the "JCo" but at the time of the test, says' com.sap.mw.jco.JCO $ Exception: (103) RFC_ERROR_LOGON_FAILURE "name or password incorrect .
I managed to also create the portal systems, "System Administration -> System Configuration -> Content Portal" and to test it fails on "Test Connection with Connector", which as noted is associated with the connectors "JCo".
For the creation of the system, I think I should create something in the Visual Administrator ", but within the documentation that I do not see anything about it.
thanks for your help! -
A problem with this webpage caused Internet Explorer (IE9) to close and reopen the tab
I have IE9 (using 32-bit version) installed on a relatively new laptop with Windows 7 64-bit. Up until last weekend IE9 worked fine and Flash Player worked fine too.
At the weekend a webpage asked for Flash Player to be updated - which I did. Ever since then whenever I go to a webpage needing Flash Player I get the message "A problem with this webpage caused Internet Explorer to close and reopen the tab". This happens twice and then an IE9 error page.
I have read the discussions in here about the problems with Flash Player 10.3 and have tried the various solutions. I have updated to 10.3.181.16 having tried 15 and 14 previously. Same problem.
I have reset IE9. Same problem.
I have disabled all add-ons which stops the problem. If I enable just the Flash Player add-on then the problem recurs. Since there are so many webpages that use Flash I do not want to run my browser without this add-on running.
If I enable the add-on and run IE9 using software rendering instead of GPU rendering then I don't get the problem. However, this isn't exactly making the best use of the resources on my laptop.
This may well all be related to the 10.3 problems but no one seems to have mentioned having a problem with tabs closing and reopening so I thought I would post on here to check.
Any suggestions for how to solve this (other than using software rendering)?Thanks again for your reply. I appreciate the time you have taken to respond.
I think, however, you misunderstand the problem. IE9 does not reopen the tabs on just one website - it is doing this on every website that needs Flash Player. Therefore, running in Compatibility mode is not an option. In fact, because IE9 reopens the tabs so quickly and then ends up with an error page, I cannot even click the Compatibility button anyway.
I could use ActiveX filtering - true. All that this means is that Flash does not play on any of the websites. When I want to re-enable ActiveX for a particular website where I need to see the Flash Player item, this just triggers the error.
This problem also happened on .14, .15 and well as the current .16 version. It did not happen with the previous version of Flash Player that I had on the system (version 10.2 I think).
The fact is that either Flash Player or IE9 or both is/are broken. The two choices I am still left with are:
1. Use software rendering (which contradicts the latest advertisements for IE9 about unleashing the power of IE)
2. Use another browser - I have no problems with either Firefox or Chrome
