Using CWDIO object in a nonvisual application

I am writing an SNMP agent DLL in Visual C++ 6.0 that needs to get data from a PCI-DIO-96 board. I have CW DAQ 3.0.1.
The problem is that the CWDIO object is not available after #import'ing the typelib into by project. All the other objects (e.g. CWDIOLine) are available.
The application does not have a GUI, so I cannot place the DIO control on a form. It must be dynamically created.
How can this be solved?

Greetings,
There are a number of Component Works examples for the older version of software you are running located at the following FTP address. Please extract the contents of this ZIP file and you will find a number of DIO examples.

Logging Java objects and threads. Application sampling.

I am using a laptop to run my application on. It uses windows XP and it is the only application running on that machine. I use TCP and serial port to communicate to other devices. My application is supposed to use up to 300M of memory but apparently it using much more than that. The laptop physical memory size is 512M. I am wondering if there is a way to sample my application periodically. What I mean by that is, after the applications runs I want to run at the same time kind of profiler that every, let us say, 10 minutes logs the number of objects created and what those objects are or what the current ones are. The number of threads running and what are their names. I want to know what is using all of this memory. The memory usage goes up to about 420M. As a result, the application throws out of memory exception. I believe I can get the number of threads running but do not know how to get their names. I need to know all of that so I would go into my code and see where it is happening and try to solve the problem. One of the ways I have in my mind now is to put a print out everywhere I create an object or thread, but that�s very expensive. Any hints or tips could be useful.
Thank you in advance.
P.S.:
I do not want to run a profiler such as JProfiler because the application is running live and I do not have access to it. I want to embed these logs into the application itself and rerun it on a live system.

As a first thought, I'm guessing that you're merely thinking that your program will not exceed 300 megabytes just based on the -Xmx300M command you may be passing your program. This is a max heap size, not the max footprint your program will take. Be aware that this can go beyond the scope of 300 MB....
Now, if you want very detailed information about processes, memory usage, etc, you might be able to keep track of it yourself, but if you want this information from a system-level sort of thing you will not get it, as one of the major points of Java is that it does not care about a lot of system specifics.
Now, if you're really interested in keeping track of threads, I don't see why you could not just write to a log file every time you spawn a new thread of a particular kind.

Getting 'File not found' error while using server object model code

Hi,
I am using server object model code to pull list data in a console application. My machine has standalone installation of SP 2010. I am getting error 'File Not Found', however the same operation is working fine with client object model code.
Code I am using:
string strURL=http://servername/sites/sitename;
SPSite siteObj=new SPSite (strURL); //getting error here.
I have already checked the below,
1. Framework being used is 3.5.
2. I have proper access to site.
3. Running visual studio as admin.
Any help is much appreciated.
thanks
Tarique
thanks and regards Tarique Aslam

Hello Tarique ,
Couple of pints need to check:
1. User running the console application needs to have at least read permission to the SharePoint databases
2. Set application by changing the "Platform target:" option on the "Build" to "Any CPU"

RE: Using Drop-Down List in Express Application

The easiest way to do this is to define a domain for Gender that maps to
a droplist widget. ForteExpress will then automatically display the
widget in any ArrayWindow or FormWindow in which Gender appears. (I
don't think outlinefields support this widget.) There is a documented
customization for adding SQL to the domain to automatically fill it, but
we've found this to be a performance drag. What we usually do is cache
this type of list information on the client, usually by loading it into
arrays of listelement in a service object at user logon. The list is
then ready to go whenever a window needs it, and you can set the element
list of the droplist in PostOpenInit or wherever it seems appropriate.

Subject: Using Drop-Down List in Express Application
On an Express generated Form window I want to use a drop-down list to
define the list of valid values for a database field. The underlying
database field could have a datatype of either integer or character.
For example, on the database we have a Gender column defined. I want to
use a drop-down list that displays descriptions of "Male" and "Female" for
allowed database values of "M" and "F". The Gender column is updateable on
the window.
Any suggestions on the best way to do this? Would we need to do anything
different on Array windows?

Why can't you use PipedXputStream in other than threaded application

I have need for usage of these in a non-threaded application, however the Javadoc indicate this should not be done.
"Attempting to use both objects from a single thread is not recommended, as it may deadlock the thread."
As the Java community is composed of some brilliant people, I am curious as to why any limitation of this sort has not been fixed/addressed?
What is the root cause of these deadlock situations?
Thanks in advance.

And that avoids the situation were you could be trying to write more than the stream buffer can hold or trying to read more than you wrote to the stream.
data = getData();
outPipe.write(data);
data = inPipe.read();
doSomethingWith(data);
// is just a roundabout way of coding
doSomethingWith(getData());

Recent loss of embedded QT movies on many page for IE7 using ActiveX object

I have many pages that allow you to select from 4 video formats including QT .mov. An example is at http://www.cwdjr.net/video4/cancanL.php . The QT object uses ActiveX when on IE only(I use Windows conditional comments) and an ordinary object for most other browsers. Until sometime very recently all of these pages worked when you select the QT file. Now QT works on none of them. I suspected the problem might be due to a very recent Windows XP update which is a large one including .NET updates and other things(K8951847) X 86. I was able to restore to a day before this update, but this did not solve the problem. Of course some portions of some updates can not be removed be restoring to an earlier time, so the result does not prove the update was not at fault.
The involved pages are mostly written in php on the server, so you will not be able to see very much by viewing the source code. To make the problem more simple to view, I made a test page for QT only and with the ActiveX object only. Thus this test page can not be viewed on most browsers that do not support ActiveX. The test page is at http://www.cwdjr.info/broadbandMedia/formatsAX/qtmovtest2.php . Since I serve pages as valid xhtml 1.1 using the correct mime type application xhtml+xml, no IE browser can view the page, since no IE browser can support xhtml served properly. Thus I have a php include at the very top for header exchange between the browser and server. If this says the page does not support the mime type for xhtml, then php using regular expressions, etc is used to rewrite the page as html 4.01 strict for the outmoded browser. Thus don't be surprised if you find some pages in xhtml and others in html when you check properties.
The ActiveX object used for QT on the test page is below:
QT MOV
(CLICK ABOVE LINK IF NO PLAYER)
<object classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" width="400" height="295" codebase="http://www.apple.com/qtactivex/qtplugin.cab">
<param name="autoplay" value="true" />
<param name="controller" value="true" />
<param name="kioskmode" value="true" />
<param name="src" value="http://www.cwdjr.info/movie/cancan.mov" />
</object>
Once the page comes up on IE7, it is rather slow to respond. Then it gives:
"Web site wants to install the following ActiveX control: 'Quick Time' from 'Apple Inc'".
If you do try to install, nothing happens. In contrast to my regular pages, I added the code show above just before the start of the object. Clicking this on will bring up the QT video, but of course it is not embedded on the desired page. This may work as a temporary fix for IE. I likely can hide it from other browsers by enclosing it in Microsoft conditional comments.
I would be interested if anyone else has had such a problem recently or any ideas concerning this strange response on IE7. I am talking about viewing the page on the server. Since this is a php page it can be viewed locally only if you have a server installed on your computer and I do not. The pages with the first url example given above have operated well on IE7, Firefox, Opera, Safari for Windows, Flock, K-Meleon, Google Chrome and SeaMonkey. There are a few players that have some issues with some of the formats, but this and the fact that some players may not be installed is the reason for offering the video in 4 formats. I sometimes offer high broadband versions as well as low broadband versions.
It seems I spend more time correcting IE issues than for all of the other mentioned browsers combined.

Thanks for the reference. I use nearly no JS anymore, since it often causes problems with true xhtml served properly even when you use external script files. Often one can use php script on the server and avoid these problems. When one serves as true xhtml using the correct mime type of application/xhtml+xml, the page is parsed with a very strict xml parser rather than a loose-as-a-goose html parser. (If one serves a page written in xhtml code as mime text/html, as is incorrectly done perhaps 99% of the time, you are using only html, not xhtml, and are fooling only yourself. The page is parsed as html instead of xhtml.) The xml parser has to be very strict to account for any possible xml content. Even a single, or even several, errors often will not prevent a html page from showing, but even a single error on an xhtml page served properly will often get an error report from the xml parser rather than a view of the page. One of the most laughable examples of misunderstanding of this issue is the home page of Microsoft. It claims to be xhtml. However it is served as text/html and thus would be better written in html 4.01 in the first place. Moreover, if you validate the page as xhtml at w3c, you find hundreds of xhtml errors. If Microsoft served their home page properly as application/xhtml+xml it of course would not work on any IE browser, at least through IE7, since none of these IE browsers can handle true xhtml. In addition the page likely would not show up on any browser if served as true xhtml until all of the hundreds of xml and other errors on the page were corrected. Instead, one likely would get a very long error report rather than a view of the page.
Back to JS, document.write will not work in properly served xhtml, because it easily could produce code with XML errors. For instance it might produce code that contains an unclosed tag, which is a major xml error that can cause an xml device to malfunction. The xml parser thus rightly finds document.write as an error and prevents viewing of the page. However one often can generate the same code as document.write would produce on a browser with php on the server. The finished code is what gets downloaded to the browser, so the xml parser can check everything in the finished code rather than quess what a JS document.write might produce. And don't think you can sweep document.write under the rug by using an external JS file. The very strict xml parser finds it.
Of course embed has never been a w3c tag, but rather is a bad hangover from the browser war era, a gift of Netscape. No page that includes embed can validate as w3c xhtml or xml of any flavor, at least through xhtml 1.1. However the page may work, despite the error, if server as text/html.
All I know is that something has happened recently that has caused my problem to surface. It likely has to do with some change in the XP OS or IE browser. I have tried viewing several pages written by others that use many types of code for .mov, and all of them I have viewed that use an ActiveX embed for the benefit of IE now have the problem I mentioned. If anyone else with XP and nearly all updates, including the very recent one I mentioned, and the most recent version of QT has had this problem, I could be more confident that the problem comes from an external source. If not, it is still possible the sudden change could be something concerning a specific issue that has developed in my computer.
Again, thanks for the JS reference. Some of this likely can translate into php so I can compare how the JS and php server script I am using relate.

Business Objects, external services and application services in CAs

Hi All,
right now we are developing our first eSOA Composite Application with CE and I have some questions regarding Business Objects, the import of external services and the development of application services.
As I understood there are two ways to provide business functionality for composite applications:
a. Import backend functionality as an external service (e.g. BAPI, RFC) at the CAF, build the application service which can be used as a callable object for UIs or the GPs
b. Develop a local Business Object (in CAF) providing the business logic, create the application service which again can be used as a callable object. Furthermore the application service can be exposed as a Web Service (external service).
My questions:
1. When is it appropriate to to import external services in stead of developing local BOs?
2. Under what conditions is it advisable to (solely) develop local BOs?
3. What are the advantages / disadvantages regarding the reusability of the services (in option a and b)?
Note: We are developing on NetWeaver 2004s.
Please let me know, if you need more information to answer the questions!
Thanks for your advice in advance,
Regards,
Ivonne

Hi Ivonne,
first of all, the CAF Business Objects (BOs) itself don't contain any business logic, they're basically just local database tables (with some CRUD services on top).
Business logic is implemented in Application Services (AS).
Now, regarding local BO's vs. external services, it depends on your use case. If the data is already available somewhere in your backend system it makes sense to use external services. For instance you wouldn't want to store business partners all over different composites. For data that is specific to your composite (in particular configuration, customizing etc.) and not likely to be reused by other applications you should use local BOs.
Accessing local BO's is also much faster than calling external services.
You can do reuse in both scenarios, since the CAF services can be exposed as web services.
Regards,
Christian

When I print to PDF using Acrobat 11 Pro from any application the acrobat Reader does not launch automatically. Associations are correct. Thx for your help, Bruce

When I print to PDF using Acrobat 11 Pro from any application the acrobat Reader does not launch automatically. Associations are correct. Happens from Chrome, IE, Word, Excel, Powerpoint. Previously had deskPDF installed but uninstalled correctly. Can't find a preference setting for the auto launch. Thx for your help, Bruce

A simple way is to flatten the form fields, which converts the field appearances to regular page contents. You can do this with JavaScript or PDF Optimizer (Advanced > PDF Optimizer > Discard Objects > Flatten form fields). A very nice script that adds a custom menu item can be found here: http://www.uvsar.com/projects/acrobat/flattener/

Using tag OBJECT on a machine with multiple jre versions

Dear friends,
i guess that this question has been already answered, but i can't find the thread with all infos i need.
So please excuse me if i'm redundant.
This is my problem:
i have a web application that runs an applet, embedded in an html page;
by now the applet is loaded with the standard tag <APPLET>.
I found many Sun's official pages talking about the use of OBJECT tag to specify the jre version that is supposed to run the applet.
I tried many ways but i can't reach the way to avoid loading the applet with the latest jre installed on my pc.
Here is the code of my OBJECT:
<OBJECT NAME="client" CLASSID="clsid:CAFEEFAC-0014-0002-0009-ABCDEFFEDCBB" HEIGHT="38" WIDTH="335" >
                    <PARAM NAME="NAME" VALUE="client">
                    <PARAM name="type" value="application/x-java-applet;jpi-version=1.4.2_09">
                         <PARAM NAME="CODE" VALUE="it.fabio.client">
                         <PARAM NAME="CODEBASE" VALUE="/myapp">
                         <PARAM NAME="ARCHIVE" VALUE="mylib.jar">
               </OBJECT>The machines where the application is deployed have the 1.4.2_09 and the 1.5.0_03 jre versions, but my applet runs only on 1.4.2_09 version.
So i have to find a way to tell the browser which jre has to be called.
Thanks in advance for help.
Regards

Wait a second...there is more to that error message that I overlooked before.
There might be something other than just the way I set the CODE and CODEBASE parameters wrong here
Any ideas?

Extract account Based COPA from R/3 using Business Object data services

Hello,
We have a requirement to extract Account Based COPA from SAP R/3 to Teradata using Business Objects data services.
I have read couple of white papers which give information on Rapid Marts( which are built in packages) already available for some applications like inventory, GL, AP, AR etc. But I could not find anything for COPA.
Would anyone give me any information on how to use BO data services for COPA?
Also if there is no rapid mart available for COPA, does anyone know how to create custom data marts in BO Data services?
Is there any document available on this?
Please respond as soon as possible.
Thanks.

Hi,
this forum is for the SAP Integration Kit. Would suggest you post your question into the EIM area for Data Services.

The following code shows how to use REST/Ajax to upload a document to a document set.
function uploadToDocumentSet(filename, content) {
appweburl = decodeURIComponent(getQueryStringParameter('SPAppWebUrl'));
hostweburl = decodeURIComponent(getQueryStringParameter('SPHostUrl'));
var restSource = appweburl +
"/_api/SP.AppContextSite(@target)/web/GetFolderByServerRelativeUrl('/restdocuments/testds')/files/add(url='" + filename + "',overwrite=true)?@target='" + hostweburl + "'";
var dfd = $.Deferred();
$.ajax(
'url': restSource,
'method': 'POST',
'data': content,
processData: false,
timeout:1000000,
'headers': {
'accept': 'application/json;odata=verbose',

'success': function (data) {
var d = data;
dfd.resolve(d);
'error': function (err,textStatus,errorThrown) {
dfd.reject(err);

Then when this code returns you can use the following to update the metadata of the new document.
function updateMetadataNoVersion(fileUrl) {
appweburl = decodeURIComponent(getQueryStringParameter('SPAppWebUrl'));
hostweburl = decodeURIComponent(getQueryStringParameter('SPHostUrl'));

Is there a way to use bpm object in jsp (java)

hello
i could see that the bpm object can be used in jsp with javascript and fuego tag. but is there a way to use bpm object with java code?
thank you!

Suppose a Servlet/JSP calls java classes. In the java
functions of those classes, is there a way to get and
set attributes with application/session scope
directly? Thanks.Only by passing a reference to those classes (or by tying in to the framework/container).

Question about using file objects

Hi,
I have two somewhat related issues in using file objects.
In one app, a simple swing gui that passes a file to a sax parsing class and reports back any errors, if I parse a file using the app, then try to edit the file I'm parsing (in another application) and save, I get an error message. I need to close the parsing app before I can save the file.
In another app I wrote, one that takes a group of files and runs an xslt stylesheet on them, if I select too many files, I get an OutOfMemory error, which leads me to believe that as the files go through multilple processes, they stay alive on the heap.
a file object is basically just a pathname, right? If I'm not using a BufferedWriter, or InputStreamReader or whatever, you can't really close a file...will the notifiy() method let the jvm know that it can let go of the file?
thanks,
bp

A File object is just a path, it doesn't open the file or lock it, etc.. But if you are parsing the file, you must be opening (and forgetting to close it).

How to organize the context object through out the application process

Hi,
Here in my application is using the following steps for a process.
- Login
- Search
- Update
- Logout
In those above steps, Login, Search, and Update actions are touching to database/LDAP every time. In each time, Im creating new Context object, I think this is a bad approach. When I hit the login, I need to get the connection object and use that for rest of the actions(search and update).
So can we organize the single context object through out the application? And where do we need to close the Context object?

Don't worry about it. The provider will reuse connections behind the scenes. They're not tied directly to Contexts.
