Catching Events from Com side using ActiveX bridge

Hi,
I have packaged a java swing application into an activex control using the ActiveX bridge. I now need to be able to fire events from my java code which the com/VB code needs to be able to trap. The event handler on the com side looks like this: function(BSTR param1, BSTR param2, BSTR param3), but the java event model only allows passing the EventObject in the param for the introspector to work. How do I fire an activex event that the com client is able to trap??

Thanks, beders. Your solutions above works, although I found the only way to install the SDK was to the use following URL rather then the one beders suggested:
http://www.microsoft.com/msdownload/platformsdk/sdkupdate/XPSP2FULLInstall.htm
This SDK is the full one and not just the Core SDK so may take a little longer to download.
You also need to ensure that the location to cmd.exe (ie. C:\WINDOWS\system32) is on the path variable otherwise SetEnv.bat fails when it calls cmd.

How to control and display video from IP camera using ActiveX control over Internet.

Hello,
I need to control my IP cameras over the internet. I need to log into the cameras and then display the video. There's an ActiveX control registered on the computer and works fine with IE to access and control the cameras. Controlling the cameras using IE works fairly well, but there are some quirks that I'd like to eliminate by using my own custom code.
Has anyone created a vi that controls a Foscam FI8905W over the Internet? I’ve attempted, but I keep getting a catastrophic failure when I try to call ManagementConnect Method in the DVM_IPCam2 ActiveX Control Module V1.0. I'm not sure whether I need to establish an IP connection with the cameras first, or allow the ActiveX control to establish it for me.
Some example code would be greatly appreciated. Running LabVIEW 2011 on a Win7 32bit. Even some code used to control a similar device using ActiveX over Internet would be helpful.

I have an example vi for interfacing to the foscam activex.
I plan on using mouse click events within the activex window to trigger the PT function.
I only have the basic up/down/right/left directions and not the down-right/down-left/up-right/up-left in the enum. You can load the camera's web page and view the source to see the Java script code that uses the activex control. There are definitions for the other directions.
I had to mark the control as "Disabled" to keep click events from going to the activex control. If I double click the control, it goes full screen. If I then click on it to get out of full screen mode the video never returns or returns to the wrong spot in the VI.

Catch Event from a FileDownload!!!

Hey magical people
Somebody knows how can i catch an event from Element UI FileDownload?
Thanks for all!!!

A. Van de Camp,
You can create two iViews that communicate with each other on the same page, using client-side eventing, so that the output of the first iView serves as the input to the second. Eventing in the portal is based on the use of the Enterprise Portal Client Manager (EPCM), an object defined by the portal client framework to handle functions such as client eventing.
To define eventing between an iView created and existing in the portal(web dynpro iview), and an iView created in Visual Composer:
1.Check the properties of the existing portal iView and find out its EPCM event name.
2. In Storyboard, open the iView that is to be the second part of the eventing scenario and create the required port: as input or as output.
3. Double-click the newly-created port and in the Configure Element task panel, enter the portal event name in the Signal name field and the EPCM event in the EPCM event field.

Sami

How to catch events from SAP

Hi everybody:
I'm trying to set an event in SAP and catch it from a .NET progam using the .NET Connector.
I have sow the function BP_EVENT_RISE but it seems it doesn't help enough.
We want to verify if the users have use an especific transaction inside SAP program. We have user exits created and we only need to indicate over the .NET program who is listening for some event.
How can I solve this?
We are not using Business Connector.
I will appreciate any suggestion.

The User Exit only reflects one step of exit performed by the user.
The events that i need to perform have the objetive to inform that some task have been performed inside SAP, a complete task, not only knowing that the user have finished his day work.
The idea it's to know that the user finished a new human resource registration, beyond it's well done, I need to know the number of the human resource.
On this point, I need to continue the registration in an automatic way over the security system (active directory), send an event to the person who have to regiter him over the corporate system and configure his mail (if needed).
I have look and evaluate the advise, but it dosen't solve my needs. I have to wait until my user finished his job (or ask him to exit) each time he register a new human resorce, that's not my idea.
Any other sugestion?. Thanks.

Catching event from canvas class

Hi,
I want to catch an event from MyCanvas class/obect to MyMidlet class/object. I have implemented keypressed method in MyCanvas. can i use it pr do i have to do something else..
Any ideas?
Cheers
Indy

hi mlk!
well, i want to catch Canvas.Fire event. sorry but i should have given you an idea of the code. well here it is:
public class MyMIDlet extends MIDlet implements CommandListener {
private Display display;
private MyCanvas canvas;
private Command exitCommand = new Command("Exit", Command.SCREEN, 1 );
public MyMIDlet(){
canvas = new MyCanvas(this);
protected void startApp(){
display.setCurrent(canvas);
canvas.addComman(exitCommand);
canvas.setCommandListener(this);
public void commandAction( Command c, Displayable d ){
     if( c == exitCommand ){
     exit();
public class MyCanvas extends Canvas{
protected void keyPressed(int keyCode) {
     if(keyCode < 0)
     int key = getGameAction(keyCode);
if(key == Canvas.FIRE){
     System.out.println("FIRE");
So, when Canvas.FIRE is 'pressed' i want MyMIDLET to know that it happend..
thanks again

Catch chose from list results, & use it

The following script will activate/deactivate layers based on the letter {A, E, D, F} chosen from the list, then export single page (w 3 digits for the page number section) PDF. The problem I have I don't know to trap or cacth the results of whatever is chosen from the list & use it to name the pdf. If file name is ABC01_A_100.indd & the letter chosen from the list is "E" then final pdf should be ABC01_E_100.pdf. If the letter chosen from the list is D then final pdf is ABC_D_100.pdf. Basically what is changing whatever is between the two underscores _?_
I can see the results on the events window. How can I capture the results of whatever is chosen from list? I tried return statement but no success at all.
•Then the other question is if i use choose from list with multiple selection allowed in which I can select more letters: A", "E", "D", "F" how can I output different PDFs with whatever is chosen from the list (with the correct layers activated/deactivated) & file names; ABC01_E_100.pdf, ABC01_F_100.pdf, ABC01_F_100.pdf.

Catching events on Desktop , without using any AWT or Swing components.

How can I catch events(for eg: mouse clicks) on the Desktop? I do not want to use any AWT or Swing components in my application.
Also, i want to get events even some other java/non-java application windows are visible on desktop, as long as my application is running.

Myrequirement is to capture all AWT events, regardless of on which component its being happened.
I mean I have to capture events outside the current running application (on desktop and any other java/no-java appliation windows also).
I couldn't find any other forum which discusses about event handling.
This is part of my app. other end extensively uses awt.

Using ActiveX bridge

Hello!
Has anyone used the ActiveX Bridge with TopLink? Does it work???

Well, I would like to take advantage of TopLink and create my business components all in Java and reuse them in any programming language for Windows, like Delphi or Visual Basic for example. If I encapsulate my queries into JavaBeans is it possible to package it into an ActiveX with Sun's ActiveX bridge?
So I would have only an windows interface in any language and all the business in Java...

Catch event from Web Dynpro for Java

Dear guru's,
we have a working Web Dynpro for Java. It delivers a company code that needs to be routed to a visual composer model. In the Web Dynpro we use the WDPortalEventing.fire command to trigger an event named 'ShowCompanyCode' in namespace com.sap.vc:epcm. In the visual composer, I used a 'signal in' for the same namespace and event name. However, the supplied value for the company code is not received. Both iviews (from VC and Web Dynpro) are on one page.
I have enabled the flash debug console and did some testing with a VC model that consists of two iviews on one page. Here it does work. I have found some differences in the debug output that points in a direction.
In the case of the VC iviews, I get the following string in the debug console: signalinAHAPP -<Params version="2" ><Row STR1="1000" /></Params>. This results in a correct transfer of company code value '1000'.
When getting the info from the Web Dynpro iview, I get the following string: signalinAHAO8 -1000. It seems that the web dynpro does not supply the values in a correct way. However, the same mechanism is used to supply the data to another web dynpro iview and that works fine.
Do we have to use special coding to be able to fire the event to a VC iview? Any help will be appreciated and points will be awarded!
Thanks,
Arno

Passing strings to a LAbVIEW application from Visual-C++ using ActiveX

Hello all,
I have built a LabVIEW application with ActiveX server enabled. I can
start the application, and can read and set simple control values like
numerics.
But now I want to pass (SetControlValue) strings and read (GetControlValue) strings from controls.
After searching a whole day for examples or HowTos I found nothing. Can
anyone give me tip where I can find something about that?
Examples are also appreciated.
Best regards
Heinrich Eidloth

The problem you are running into is that a BSTR is not a normal string (%s in the printf), but a wide character string (i.e., two bytes per character) string with the size stored in it. If the string contains ASCII characters, such as Hello World, then the one of the bytes per character is 0 (for example, 'H' would be 0x48 0x0).
When printf sees this, it thinks that it is a normal, null terminated string of "H". That is what you are seeing. You might try the %S (capital S) since that tells it the string is a wide character string.
Also note that BSTR's are part of the COM (Automation) system and so are don't freed with a delete or free() statement. Instead you need to release the memory with a SysFreeString() call.
If you aren't very familiar with C/C++, then you've taken on an advanced topic on top of a complicated language. If you can, you might want to try using either VB6 or .NET (C# or VB.NET). Those languages handle all of this for you automatically and you don't have to worry about freeing the memory.
If not, the book I started with to learn COM programming was this one (http://www.amazon.com/gp/product/1572313498/104-3574382-6511132?v=glance&n=283155&n=507846&s=books&v...).

Problem catching events from my ComboBoxItemRenderer

Hi all,
I have a problem catching a custom event dispatched by my
custom ComboBoxItemRenderer. In the renderer I dispatch an event as
follows:
dispatchEvent(new Event("smallTest",true,true));
As this is a bubbling event i expected to be able to catch it
in one of the parent containers. However, the opposite is true.
Then, lowering my goals i tried to catch the MouseEvent.CLICK event
raised by the button in the ComboBoxItemRenderer. I failed in the
same way...
Somebody has a clue? Thanks in advance!
(the following is an isolated description of my small problem

Listening from the combobox (cb) didn't work. Found out that
the hierarchical parent list from the view of the itemrenderer was
as follows:

[object Stage]
For now, i managed to fix the problem by listening from the
systemManager but this is more like a hack.

Raise event from client side

Dear Experts,
   I would like to raise a event to SAP server by using sapevt.exe.
1. I have put sapevt.exe and DEFAULT.PFL in a special folder in the server and shared it.
2. I have created a bat file with following commands and distributed it to client stations:
   net use z:
sapserver\sapevt
   z:
   sapevt EVENT1 pf = DEFAULT.PFL
   net use z: /d
   exit
3. When I run the bat file in client stations, event is not raised.
   Log in dev_evt:
   Trace File of External Event Raiser (Level = 0, Append = 1)
   EventID: EVENT1
   SAP message server host: sappserver
   SAP message server service (old): sapmsPRD
ERROR ***: MsAttach (host=sappserver, serv=sapmsPRD), rc = -100
   But when I direct run sapevt.exe (sapevt EVENT1 pf = DEFAULT.PFL) in server side, event is raised successfully.
Please advice how to fix it. Thanks.

Hi,
Do you have the entry sapmsPRD in the services file on the client stations ?

Firing events from a Menu using Event Structure - all in the same Event Window?

I have an ap where I have three menus, and several selections from
those three menus. I'm trying to keep everything within the Event
Structure, but it seems that ALL of the events fired from the Menu must
be contained within one "frame" of the Event Structure, that being the
Menu Selection (user) Event. In other words, if I have 16 events that
can be fired from the menu, do I have to put them ALL in this one event
frame?
I can't seem to use a T/F indicator within the Menu Selection (user)
Event to access another Event. For example, within the Menu Selection
(user) Event, I placed a boolean named X and can turn it on with a menu
selection. Now, make a new Event Structure to look for X Value Change -
doesn't work.

I use one event, Menu Selection (user). to trap all of my menu events. Use Item Path and / or Item Tag to figure out what menu item was selected then branch code based on selection. Wtih Booleans and menus you need to update the state of the boolean on the menu by setting it True or False. It doesn't automatically toggle like you would expect.

Tactic 3D Sigma - No audio from right side using USB?

Just got my new Creative Sound Blaster Tactic 3D Sigma (phew, that's a mouthful) headset in the mail today. When I connect it to my laptop using the USB adapter, there is no audio from the right side, only the left. When I connect using analog, though, the headset works fine.
I'm on Windows 7 Professional 64-bit, and I have the latest Creative software and headset drivers installed.

Hmmm... sounds like something is wrong with the USB adapter. Did you purchase the headset direct through Creative Online Store or from your local electronics store? If you bought the headset from your local electronics store, please get in touch with them right away, these stores usually have a 30 day exchange policy.
If you purchased this through the Creative Online Store, please write to our Customer Support and ask for an RMA (Return Merchandise Authorization).
