WebUtil and dde

Does web util have any DDE related functionality?

If you want to load it into a table it would be better to transfer it onto the application server or straight onto the database and process it there (there was a thread on loading xls into the database this week on OTN).
Using webutil calls would probably be costly in terms of performance.

Webutil and DDE problem

Hello,
We are running into a problem web-enabling a client-server Forms application. We are using WebUtil for HOST and OLE calls and sending files between client and app-server and it all works really marvelous. But we noticed that the DDE package is not available in WebUtil. Unfortunately for us, we are using DDE calls to interact with MS Word (for example merging template letters with address-data) and MS Excel (filling out template sheets with data).
Can you tell me if DDE will be available in future releases of WebUtil? And, if not, is it (generally) possible to rewrite the DDE-calls to OLE-calls using WebUtil's CLIENT_OLE functions? And what DDE-functionality maps to the corresponding OLE-functionality?
Or, if it's not possible to rewrite DDE to OLE, what are the alternatives? Removing the interaction between web-forms and MS Office is NOT an option ;-)
Thanks in advance,
H. Verschuren

WebUtil and DDE-package

Hello,
does anybody know, if there will be something like a CLIENT_DDE-package (related to the old DDE-package of forms) in webutil. The first announcements of Oracle about WebUtil told so, but now there is nothing left about it.
Any suggestions?
Thank you in advance!

In forms 9i, which is on web architechture, does DDE work ?
i.e. if I want to read a .xls located on a network drive, and load that data into a table, is it possible using DDE in forms 9i.
Thanks

Webutil and SQLLDR

It used to be on the client server when we run a batch file with sqlldr from a form, a cmd window would open and we can actually see a count of the records, and if we want we could make it that the user would have to click a button to close the cmd window and return to the form.
Now with the web version and webutil, I was able to make the batch file work and the data is loaded into a table, however, when the cmd window opens, it stays blank and you cannot see what is happening.
Is there a way to get the same performance as the client server version?
Thanks
George

Hi,
You can read the output/log file using textio (implemented through webutil)
and give a message to the end user.
Alternatively use the webutil host to open a command window and pass batch file which will do the sql ldr ....

Webutil and Office 2010

Has anyone else experienced any issues with webutil and MS Office 2010? We save .xls files to .csv and upload via webutil (10g). We are getting an error that the file on the root directory cannot be found, although it does exist. We found that if we saved as Office 2003 and then as a .csv file, it sometimes works. We never had this problem before upgrading to Office 2010. I ran the form in debug and confirmed it is bombing out on the client_text_io open command.
thanks in advance

I think we figured out it was also a Windows7 issue more than Excel. The Windows7 doesn't have a temp directory any longer, but we were able to create another directory (with a more meaningful name) and read/write to it. The webutil works fine now. Seemed like it was maybe a root directory permissions problem.
thanks

WebUtil and ActiveX

What is the correlation between WebUtil and ActiveX?
The reason I ask is that we have successfully installed WebUtil on our 9iAS R2 apps server and the Webutil forms that were created all work perfectly on site.
However our WAN covers sites all over the UK and the majoiry of these sites have all ActiveX settings disabled for security reasons. When accessing from one of these sites the form correctly loads all the .dll and .jar files but the CLIENT_TEXT_IO procedure will not operate.

... one thing I forgot. Duncan Mills, who could answer this question a lot better than I can, is on vacation this week.

Webutil and XP

Hi,
We have a form in which we use the call web.show_document(l_url, '_blank'), where l_url is a location of an html file on a local pc. Then in a
seperate browser the html file is shown.This works fine for our application.
Now some users are migrated to XP as OS, instead if 2000.. For these users no webbrowser is started after the call to show_document. In the
javaconsole is also no error seen. It is just that nothing happens.
In IE and Firefox this problem occurs.
Is there an issue between webutil and XP? Or is this a different kind of problem?
Richard

Thx for quick reply..
We tried it.. But, problem keeps existing...
We also tried XP and IE6... again no browser appears ...

Webutil and Outlook - I get a WUO-714 and WUO-705 error

Hi,
I have installed webutil and it loads fine an all. However, I have a problem with a Microsoft Outlook integration. I am simply trying open an Outlook mail item, which is then filled out with some data. Pressing the Send button is up to the user.
Everything works until the line "mailitem2 := CLIENT_OLE2.INVOKE_obj(MailItem,'Display');" is called. Here Forms reports back: "100501: non-Oracle exception" and the java console gives a WUO-714 and WUO-705. The problems seems to be the Display method. At that point, despite errors, I do have an open, visible mail item with the proper data filled in. (In this process I noticed that the final invoke_obj should happen after you write stuff into the To, Subject and Body of the mail, but that's besides the point.)
Any advice you can offer is welcome.
Sincerely,
Jesper Vad Kristensen

OLE2 and DDE package books

Hi All,
I need to fully understand OLE2 and DDE package. Pressing F1 provides very limited help for me. Anyone here have or know some links of any reading materials(e-books, documentation)?
Please share... I'm drowned with my tasks here.
Thanks!

DDE is seriously outdated and should only be considered as a last resort. As for OLE2, concern yourself not with learning the OLE2 package, but instead, with understanding OLE automation. The OLE2 package is just a wrapper that makes it possible to manipulate OLE automation servers from PL/SQL. Once you understand OLE, using OLE2 should come easily.
I learned OLE automation as a Visual Basic developer, before ever working with Oracle, and found it to be fairly straightforward. The easiest and cheapest way to learn OLE automation is by using Microsoft's Visual Basic for Applications IDE -- an Office component. Search this forum using keywords VBA and Tutorial, and you will find information that should hopefully prove helpful.
As for Mark's assertion that XML provides a simpler solution, there are important differences between the XML and OLE approaches. The XML approach involves simply creating a document, whereas the OLE approach involves instructing the OLE server application to create a document. XML might be perfect, for example, if you wish to create Word documents on a *NIX server. On the other hand, when your environment permits it, OLE makes it possible to leverage application functionality, like Excel's data analysis functions.

Java and DDE

I want to print a pdf file from within java. This can be done using the Acrobat Reader and DDE. Does anyone know if DDE can be used with java? if so, could you send an example?
Thanks

There is a freeware library called FOP from Apache that will handle all sorts of PDF operations. The link is

Java and DDE/COM

I'm using some PERL/regex software for a telnet client which only supports COM and DDE usage for communicating to other applications.
I've invested an entire day searching for a solution other than spending upwards of a thousand dollars for professional DDE software, and I've found nothing. I am still hoping that someone could advise me of where to look for information regarding creating COM objects in Java, or setting up a DDE connection between them. Something integrated like InfoBus would be nice, but it is obviously not supported by my telnet client.

http://danadler.com/jacob/
I don't know about the DDE bit though. I haven't used DDE in years and it was very unpleasant when I did. (I didn't do anything with Java with it)
I am sure it can be done... it just may be tricky.

Regarding WebUtils and Jacob

Dear all
I am following BAIG's blog for configuring WebUtil and Jacob .
http://baigsorcl.blogspot.com/2010/01/open-file-dailog-box-example-using.html
Mr Baig told to download both WebUtil and Jacob . But in 10G already Webutil is there .
So again i nned to Download and replace it ?
Or only i have to download JACOB ?

No, you don't need to download it again. It will be available for IDS.
You need to download only when you are using iAS ..
