Silverlight application (example.xap) doesn't run when call in other pages using "Object tag"

Hi!
I have silverlight 3 installed with Visual studio 2008. installation is fine.
I have created a silvelight application including a test page.
In my test page I used the "object tag" to call my application as it is suggested since silverlight 3:
<object type="application/x-silverlight-2"
data="data:application/x-silverlight,"
width="450" height="220">
<param name="source" value="MySilverlightApplication.xap"/>
</object>
At the run time, using the test page my application runs as expected. But when i call the same application in another page i have created, nothing happens: the web page is blank. I wonder why it works with the test page created at the same time with the
silverlight application ( i have checked the radio button that required the test paged creation during the process of the silverlight application) and why it doesn't work with a page created separately.
Thank you for your help!

Hi Andy!
Hi Qimin!
Thank you for your helps. But i want to let you know that the html code i wrote in my post is just an example so I will complete my post with more information.
0- I have visual studio 2008 installed with silverlight 3.
1- I have created a web project with a master page (my master page has a content page )
2- I added a silvelight application: carousel.xap (during its creation I've accepted to add a test page: carouselTestPage.aspx)
3- I added a main page Home.aspx: which inherits from the master page created in step 1, then I call my silverlight application in this content page using the object tag.
Result of the tests during run time:
My silverlight application carousel.xap works fine when I test it with the
carouselTestPage.aspx.
But my silverlight application carousel.xap doesn't work with the main page I added to my web project. the web content page is blank.
Here below the script of the carouselTestPage.aspx
and for the Pages_Home:

so the application source is correctly supplied in the object tag description. so I wonder why it doesn't work with a separate content page in the same web project and work with this embedded Silverlight Test page.
Thank you for your helps.

Same URL when called from other page when called directly behaves different

Hi All,
I am working on SRM 5.0 implementation , the open catalog interface applications are called from a link from the standard ITS (thses catalog applications are developed in BSP) and then submited back to the ITS application using a URL :
va r ret_URL = "<% = hook_ur l%>" <--- this is the return URl to which catalog data is submited
d ocument.f inal . action = ret_URL;
d ocument .final .method = " P O S T ";
d ocument. final. submit ( );
This application is transfered perfectly if the catalog is called by clicking link on standard ITS application(EBP application) but if i enter the catalog URL(BSP Application URL) directly in the browser and hardcode the value of HOOK_URL (ret_url) in BSP application , the catalog is submited but it shows a blank page with javascript error 'window.opener.isLeanWP' is null or not an object .
hook_url = http://sapupd.mycompanyname.com:8002/sap/bc/gui/sap/its/bbpsc02/?~OkCode=ADDI&~Target=_top&~Caller=CTLG&~client=200&sap-client=200&~language=EN&~HTTP_CONTENT_CHARSET=utf-8
Kindly suggest the solution. We need to call the OCI application directly and submit it to ITS application using this hook_url.

PI 7.0: Error when calling an adapter by using communication channel

Hello Experts,
We have a mapping scenario for ERP -> PI -> web service. Few details from ERP will be sent via PI to Web service.
Once the web service authenticates, token and sign will be generated. Here an RFC adapter is used for configuring the RFC receiver communication channel and provided the ERP system logon details at the RFC client parameter.
An error is received as mentioned below.
Error while lookup Exception during processing the payload.Problem when calling an adapter by using communication channel CC_Rcvr_RFC_Lookup_TokenSign (Party: , Service: BS_QV6_700, Object ID: 54e904ebf3d7382a84a0f83cd292b810)

CF8 DirectoryWatcher Gateway Doesn't Run When I Overwrite a File

I've set up a Coldfusion Directory Event Gateway on my site (Win2K3 server, CF8 Ent). The DW monitors an FTP directory where my users upload a batch of 5 PDF files each week. The files are named file1.pdf, file2.pdf and so on. When my DW gateway sees an addition or a file change, it copies the file to a new location, reads the PDF's meta data and uses that to rename the file and then add an entry to a database table for that file (the table entry gets used to populate a PDF archive list on a different page). In general this all works with a few exceptions.
ISSUE 1: If I add a new file, the gateway sees it and calls my onAdd function (which actually just calls my onChange function). If I rename a file in that directory, the onChange event fires and my code runs. However, if I upload a new file1.pdf file which overwrites the old file1.pdf, nothing happens. The new file is truly different and has a new modification date. I read through the Java class and mod date is how the gateway determines a change. Now, so far am not actually FTPing a new file in, but rather just coping it in from my local machine to the server directory via a mapping.
I saw a solution for a similar issue which talked about setting up the onDelete event b/c the FTP will actually delete then add the file. Does this sound like a solution?
ISSUE 2: I had a lot of CFM files that needed to be put into the archive, so I converted those to PDFs. I then put all of them in my watch directory so my script would process them. To my surprise, the script would only load 11 files at a time. So after some tests to confirm the issue and the correct number of files, I then loaded my batch, 11 files at a time. Any ideas why this would happen?
My Specs again:
Windows 2003 Server
Coldfusion 8 Enterprise
In my config file:
checking my directory every minute (60000 milliseconds)
only checking for .pdf extension
Set an onAdd and onChange function call, but no onDelete
my onAdd function simply calls my onChange function, passing
in the CFEvent argument that it received

We had the same problem here, and I agree that it is disappointing that the DW doesn't consider that a new file. As far as a workaround, what I did was change the way our process dealt with incoming files entirely. I used to handle the files as they came in, relying on Dave Ferguson's tricks for getting around files that were still being written to or otherwise locked (thanks, Dave!). Now, instead of that, I only do one thing when a file is received: I rename it with a datestamp and write this to our db as the received filename so that the additional processes can be run on it. That way, when that same filename is used by our client again, which is every time, the DW picks it up again as a new file. I don't know if that helps or not, because it still means you lose the functionality that used to be inside the DW instead of a scheduled task, but at least you know when an actual new file is received, regardless of its name. You may even be able to put your functions inside the onChange or onDelete if you keep the reference to the original filename, then have those do your work after the file is renamed and/or moved. In our case, the DW also kept hanging every couple of days so we were missing very important files. I ended up just restarting the gateway through code as the last piece of the scheduled task that runs every 30 mins to process the files.

IAC iview doesn't run when change to another and come back

Hi,
I've defined an IAC iview tha calls an ITS services (parameters ~webgui = 1, ~generatedynpro = 1, ~simpletransaction = 1, ~transaction = ).
First time I run this iview, it runs well. I run another iview and when I come back to the first one (IAC iview), it doesn't run, it shows me a r/3 screen that let me access r/3 menu, so it doesn't run my ITS service.
I'm using ECC (ITS integrated) and I'm not using SSO.
Any idea. All contributions will be appreciated.
Thanks a lot.
Best regards,
Iván.

Hello Iván,
I think you meant ~singletransaction right? If so please remove this parameter and try again.

Screen Saver when calling and need to use the Keypad, the screen saver doesn't detect the phone has left the ear and blanks out the screen. Even ending a call is difficult as the screen blanks out within seconds

I have to use the Keypad a lot when making calls. Make the call, the Robot then asks to enter a number for a service, pull the phone down from the ear, the screen may light up for a second, but then the screen saver cuts in, blanking the screen out. Sometimes you hit the Home Key to awaken the sccreen, enter your number and then back to the ear to hear the next set of instructions. Back and forth just trying to enter the options is a pain. Sometimes even trying to end the call, the screen blanks out and you fight to try and end a call.
If I use the Speaker function the keypad works; the speakler phone is not alway appropriate.
It appears that the phone gyro, doesn't detect the phone has moved from the ear to the viewing angle. This wasn't an issue until recently and I can't remeber if it's the iPhone 5 or one of the updates. It definitly wasn't there earlier on, as I threw away an Windows 6.5 phone for the same problem.
I'm not sure if it's a hardware or software (design) issue.

It is not the gyro. This has everything to do with the iPhone's prioximity sensor.
Are you using a case that may be blocking or partially blocking the proximity sensor? If you are using the case, remove the case prior to the next call to see if the same occurs without the case.

Captivate 8: audio file doesn't work when I add it to an object slide

Hi everyone,
I have problems with the audio in Captivate 8. This doesn't work when I press an object slide (button) that has an audio file incorporated. This issue doesn't happen when I add sound to an individual slide.
I have tried to fix the problem by changing the preferences, but nothing
Any suggestion is welcomed!!
Evelyn

An audio file that is attached to an object or a slide, will play when that object or slide become visible. I don't know what you mean by 'has an audio file incorporated'? Do you mean that it is attached to the button in its audio part of the Properties, which is in the Options tab? In that case the audio will just play when that button gets visible, if it is at the start of a slide, audio will play at the start of that slide.
If you want an audio clip to play only when a button is clicked, you need to use an action 'Play audio', or make an audio object visible.

Beware: if you do this with a simple action triggered by the button, the playhead will be released if that button has a pausing point.

Why do I get error -17500 when calling a batch file using the call executable step type?

I am calling a batch file using the call executable step type. If the path to the batch file contains a space I get error -17500 and a message stating there was an error in "Post". For example the path to the batch file is "c:\TestWin\Test Files\...\Program.bat" When I run this I get the above mentioned error, however if I change my directory structure so the path is now "c:\TestWin\TestFiles\...\Program.bat" it runs fine. I use the browse feature to find my batch file so it is not me typing in a path incorrectly. I have removed the batch file and I get a different error stating that it couldn't find the file so it appears that for my error it can find the file but can't run it. I am
sure that this has something to do with the fact that batch files are written in DOS but really don't want to resort to changing my directory structure on all my test stations. Is there any way to fix this problem so I can leave a space in my path?

It appears I have figured it out. This was on another computer so I was unaware of how they used their computer. I like you got it to work in the temp directory and in fact got the program.bat file to work as long as I put it under the temp directory, but when I switched out to my TestWin directory it wouldn't work, so I removed everything from the directory except the batch file it self and it work. What I found out after adding files in one at a time is that the person had a file called "Test" with no file extension in there "c:\TestWin\" directory. Removing this file made it work. Putting the file back broke it. So it appeares that when teststand was running it followed the path saw a space and attempted to grab the "Test" file instead of bro
wsing into the "Test Files" directory. If you create a file in your temp directory called "temp" with no file extension you will see the same problem. Thank you for your help.

How to set SOAP Header When Calling Business Service (OSB) Using Split-Join

Hi,
We need to call WSDL based webservice which requires heading static content for successful call. As we need to call the same service parallely, hence we want to use Split-Join.
Looked at couple of forum links, noted that we can't play with headers while working with Split-Join.
For curiosity, just want to check any option other than using proxy as mediator in setting header information.
Regards
Venkata Madhu

Venkata,
You still have the option, if you hv n't tried this one.
To enable this capability, you must declare the header parts along with the body parts in a single request/response message in the Split-Join WSDL and in the WSDL of the proxy or business services invoked by the Split-Join. With the message parts declared in the WSDLs, SOAP header content is available to Split-Joins in the request/response message variables.
Following is an example of the message and binding definitions in the WSDL.
Message
<wsdl:message name="retrieveCustomerOverviewByIdRequestMessage">
<wsdl:part name="retrieveCustomerOverviewByIdRequest"
element="co:retrieveCustomerOverviewByIdRequest"/>
*<wsdl:part name="serviceContext" element="sc:serviceContext"/>*
</wsdl:message>
Binding
<wsdl:input>
<soap:body use="literal" parts="retrieveCustomerOverviewByIdRequest"/>
*<soap:header message="tns:retrieveCustomerOverviewByIdRequestMessage"part="serviceContext" use="literal"/>*
</wsdl:input>
hope it helps !!

No data found exception when calling a new page from existing page

hi i have a screen which has a delivery id and i am calling a new page with a different view object and a application module.I need to pass this delivery id in the main page to the view object query in the second page.
i have defined the second page view object with the following query
select country,address1,address2,address3,address4,city from hz_locations where location_id=
(select ultimate_dropoff_location_id from wsh_new_deliveries where delivery_id=:1)
what i want is to pass the delivery id in the main page to :1 in this query.
i have written the following CO code for the second page
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
String eventaction=pageContext.getParameter("xxsaneventname");
String paramval=pageContext.getParameter("xxsanparamvalue1");
OAApplicationModule deliverydetailam = pageContext.getApplicationModule(webBean);
Serializable personParamList[]= {eventaction,paramval};
if ( eventaction!=null && eventaction.equals("viewdelivery"))
deliverydetailam.invokeMethod("getdetailsmethod", personParamList);
i have written the getdetailsmethod in the application module impl
public void getdetailsmethod( String pAction, String pdeliveryId)
try
OAViewObjectImpl pervo = getWshDeliveryDetailsVO1();
String existingWhereClause = pervo.getWhereClause() ;
System.out.println(existingWhereClause);
pervo.setWhereClauseParams(null);
pervo.setWhereClause("delivery_id = :1");
pervo.setWhereClauseParam(0, new Number(pdeliveryId));
pervo.executeQuery();
pervo.setWhereClauseParams(null);
//pervo.setWhereClause(existingWhereClause);
catch(Exception exception1)
throw OAException.wrapperException(exception1);
can some body please help me to correct this one.
the exception i got is
oracle.apps.fnd.framework.OAException: No data found for region (/xxt/oracle/apps/AK/om/webui/deliverydetailpg).

Provide the complete error stack.
From the current error line it shows that your custom region/page /xxt/oracle/apps/AK/om/webui/deliverydetailpg is not present in the MDS. Did you use xmlimport to set the page xml into MDS? If yes, use jdr_utils package to confirm it is present at the right location.

Infinite blocking when calling service other than "toupper"

Hi,
We are testing (trying) Tuxedo Connector between (from) WLS 6.1 (NT) and (to)
Tuxedo 6.5 (AIX). Calling the sample service "toupper" works fine. But WLS is
blocking when calling services that do not return the result in the same buffer
as input (as toupper does). When calling a Tuxedo service that returns its result
in a buffer it newly allocates (C library), from the WLS logging we see that it
was able to get the returned data size, but then it seems to block for the data
itself. Following are the two last logged WLS messages:
Jan 4, 2002 5:30:32 PM EST> <Debug> <WTC> <]/read_dom_65_tfmh/130/-1>
Jan 4, 2002 5:30:32 PM EST> <Debug> <WTC> <]/TuxedoMuxableSocket/dispatch/90/failure=-1>
Any idea? Thanks, Eric.

See attachment (log from WLS) and following code snippet.
tupper(TPSVCINFO *rqst)
/* next line will work */
char* outMsg = rqst->data;
/* next line won't work, would get:
weblogic.wtc.jatmi.TPException: null
TPException.getDiagnostic(): 0
TPException.gettperrno(): 13
char* outMsg = (char*)tpalloc("X_OCTET", NULL, rqst->len);
for(int i = 0; i < rqst->len; i++)
out[i] = toupper(rqst->data);
/* Return the transformed buffer to the requestor. */
tpreturn(TPSUCCESS, 0, out, rqst->len, 0);

Unable to use debug mode for x64 application and debug doesn't work when target cpu set to x86

I am attempting to familiarize myself with Visual Basic programming in Visual Studio 2008, using the Visual Basic Guided Tour in Microsoft Visual Studio 2008 Documentation, and have run into a bit of a road-block. When following the lesson "It
Doesn't Work! Finding and Eliminating Run-Time Errors", the IDE does not allow me to edit the code when the debugger hits the intentionally programmed runtime error (divisor set to 0). It gives me an error that "Changes to 64 bit applications
are not allowed". I found some forum postings advising to set the project's Target CPU from "Any CPU" to "x86". However, when I do that, and re-execute the debug process, the debug fails to stop on the overflow/divide by
zero error.
How can I debug my programs when Any CPU/x64 target doesn't allow me to edit the code, and x86 target doesn't appear to recognize obvious runtime errors.

Hi Tim,
>>the IDE does not allow me to edit the code when the debugger hits the intentionally programmed runtime error (divisor set to 0). It gives me an error that "Changes to 64 bit applications are not allowed".
I'm afraid that the VS2008 has a limitation for this feature, I mean that Edit and Continue isn't supported on 64-bit.
Reference:
http://stackoverflow.com/questions/1498464/changes-to-64-bit-applications-are-not-allowed-when-debugging-in-visual-studio
http://blogs.msdn.com/b/habibh/archive/2009/10/12/how-to-edit-code-when-debugging-a-64-bit-application.aspx
But this feature has a improvement in VS2013 now:
http://blogs.msdn.com/b/visualstudioalm/archive/2013/06/26/debugging-support-for-64-bit-edit-and-continue-in-visual-studio-2013.aspx
So if possible, you could test it in the latest VS2013 version.

Running total in group header doesn't display when it's at page bottom

Post Author: Charles Denight
CA Forum: Formula
Hi, Using v.9 of Crystal Reports I've created some running totals using a cross-tab workaround to get the running totals into the group headers, but when the group header falls at the bottom of the page then the running total doesn't show up.Would appreciate knowing why and how to fix this.

Replacing an item that is malfunctioning because of a manufacturing error is the bare minimum I would expect from customer service for any electronics item.
The thing Apple does extremely well is their flat fee policy for repairs on their computers.
I managed to break my MacBook pretty seriously (logic board needed to be replaced) and I'm sure it cost them more to repair the unit than the $328 they charged me.
I probably would have been angry if it was something minor, but I'm guessing that most repairs to screens/motherboards/etc cost more than their flat fees.
