How to use mp3 files on a form standard button, instead of wav-files. Need to save space.

I would like to use mp3 files instead of Wav-files on the standard button, in the forms edit menu. I know it is possible in the interactive menu to add buttons with mp3 sound. But those buttons has not the same options and appearance as the forms buttons. We create learning books with lots of sound files in each PDF, so with wav-files the PDF gets quite heavy in Gb.

Smokerz – Thanks for the feedback. I managed to get iTunes to find the movie files on my TC by simply dragging the icons of the files on the TC into the Movies folder in iTunes. This immediately made them available for streaming on my Apple TV. Also, I learned with great relief that, despite their large size, dragging icons of my movie files into iTunes did not copy them to the C: drive on my desktop computer. Thus, it looks as if the job is pretty much done. Thanks again for your advice.

Can I use Visual Basic to covert form user data from multiple .pdf files to a single .csv file?

Can I use Visual Basic to covert form user data from multiple .pdf files to a single .csv file? If so, how?

You can automate Acrobat using IAC (InterApplication Communications), as documented in the Acrobat SDK. Your program could loop through a collection of PDFs, load them in Acrobat, extract the form data from each, and generate a CSV file that contains the data.
Acrobat can also do this with its "Merge Data Files into Spreadsheet" function, but this is a manual process.

How to use MICR fonts in Adobe forms (webdynpro java

Hi,
We have a requirement where we need to print some MICR codes (for checks) through Adobe Forms.
I have installed some true type MICR fonts in windows and Adobe Font Manager (in ADS) as well.
It is visible in the Adobe Form design time (Font palette) and when I use the font for text, it is visible in preview too. But when I run the web dynpro application, in the online form it is converted into Standard font (Times new Roman).
Is there anyway to handle this issue.
Please let me know.
I am using NWDS 7.0.1

When creating a PDF from a PPT or Keynote application on a Mac using Acrobat X Pro, how do I ensure it can be opened on a PC? Do I need to save as a particular version of Acrobat?

When creating a PDF from a PPT or Keynote application on a Mac using Acrobat X Pro, how do I ensure it can be opened on a PC? Do I need to save as a particular version of Acrobat?

The system was not my own, it was on a PC belonging to the school where I teach. The error message referred to Acrobat 9.0, so I assume that the problem is to do with the version on which the file was created being more recent than that on which I attempeted to open it.

How to Use an Image to Customize the Static Button Widget

Can I just get someone to help me figure out how to use an image to customize the static button widget, please?
I have tried using several different types of images, but none of them seem to actually change the appearance of the button.
Thanks!
Laura
Captivate 5.5

I tried to use the tools within the widget itself - it offers you the opportunity to use an image (see screenshot below).
I also opened it in Flash and tried to replace the images for one of the button styles there w/ my own, but in re-publishing the SWF from there I broke the widget. When I attempted to use the edited widget, there were no customization controls available after I inserted it (see screenshot two below).

How to use MP3 file as a clip, not background music

I have a radio spot as an MP3 file, but when I drag it into the project it automatically thinks I want it as my background music. I actually want it as a clip to play after a commercial. I have tried saving it out of QT as a movie file but it won't let me import that file in a regular import, it's grayed out. Any help would be appreciated!
Melissa

You have to have video clip of some sort in the spot where you wan the sound clip to play. It cannot just be dropped on the timeline. So what you might have to do is put a title down with a black background, drop the MP3 right on top of that title clip (dead center). Then it will attach as a repositionable sound clip.
You will also want to convert the MP3 to an AIFF in order to keep iMovie from working too hard to playback the song when you do the final export of your video project. This is a direct copy of the iTunes Help page for AIFF conversions:
Save a copy of a song in a new file format
You can convert a song to a different file format (and keep a copy of the original). For example, you can save a copy of a compressed song file such as MP3 or AAC in an uncompressed song format (AIFF or WAV).
When converting from a compressed to uncompressed file format (for example, from MP3 to AIFF), you shouldn’t notice any reduction in sound quality. However, when converting between compressed formats (for example, MP3 and AAC), you may notice a reduction in the sound quality. For the best results, if you want your music encoded in a different file format, import the music again from the original source using the newencoding format.
Important: You can’t convert iTunes Store purchases unless they’re iTunes Plus songs.
Hide
To convert a song’s file format:
Choose iTunes > Preferences, click General, and click Import Settings.
In the Import Using pop-up menu, choose the format you want to convert songs to, and click OK to save the settings.
Select one or more songs in your library and choose Advanced > Create Format Version.
The song in its original format and the newly converted song appear in your library.

How to use a custom.dll in forms 6i

Hi,
i have made a small dll using a icon-making software, that software has made a .dll of the icon I made in that software
Now i want to use that .dll in my forms 6i. (client/server)
the dll contains only one icon named 'Icon1'
would any one please tell me how can I call that icon in that .dll to view in my forms button at run time..
is this possible..??
just for clarification, for security reasons I am not using the .ico of that icon diect from hardisk in my button thats why i made a .dll of that so that the user may not be able copy my icon
thanks in advance,

Here is the doc
Doc ID:      Note:99824.1
Subject:      How to Display User-Defined Cursors and Icons in Forms
Type:      BULLETIN
Status:      PUBLISHED
     Content Type:      TEXT/X-HTML
Creation Date:      23-FEB-2000
Last Revision Date:      30-OCT-2002
PURPOSE
The purpose of this note is to explain how to display customized
cursors and icons in Forms 6.0 on Windows platform (32 bits).
Assumption is made that resources are stored in a DLL, which is
available in the path at runtime.
It is mandatory to store the cursor in a DLL to make it available
with Forms: .cur cursor files cannot be directly loaded from the
file system.
On the other hand, icons .cio files can directly be read from the
filesystem by Forms Runtime. However we will focus on icons which are
stored in a DLL.
The article is divided into two main parts:
- how to build a resource-only DLL with Visual C++ 5.0
- how to display the cursor and the icon in Forms 6.0
SCOPE & APPLICATION
The intended audience needs to have basic knowledge in Forms Builder
and also in Visual C++ (or any other Win32 compiler).
A typical environment is Forms 6.0, Visual C++ 5.0 and Windows NT.
WHAT IS A RESOURCE ?
A resource can be considered as some extra binary information that can
be added to an executable file. Windows resources are for example icons,
cursors, menus, dialog boxes, keyboard-accelerator tables and much more.
Resources are usually stored in a .rc file, which is compiled by the
resource compiler in order to provide a .res file. These compiled resources
can then be appended to a binary executable file or a DLL.
For instance, Visual C++ 5.0 includes a resource editor which allows you to
draw your icons and your cursors, and store them in a resource file.
Part I - BUILDING A RESOURCE-ONLY DLL
Consider the following setup:
- myicon.ico: icon file
- mycur.cur: cursor file
The objective of this section is to build a DLL called proj.dll which
contains both the icon and the cursor. This operation requires several steps.
Step 1: Create a project
In Visual C++, select menu File->New... In the dialog box, choose the Projects
tab and pick "Win32 Dynamic Link-Library". Fill the project name (e.g. Proj)
and the location (e.g. c:\MyProjects). Check 'Create new workspace', check
Win32 as target platform and click on OK.
This creates a directory c:\MyProjects\Proj, where necessary .rc and .cpp
files can be stored. Place the .ico and .cur files in this directory too.
Step 2: Add a resource file to the project
Create a proj.rc file, edit it and make sure it contains the following lines:
testcur CURSOR DISCARDABLE "mycur.cur"
testico ICON DISCARDABLE "myicon.ico"
This is the resource file. Using the Project->Add to Project->Files... menu,
select the proj.rc file and add it to the current project.
Step 3: Add a dummy C++ file to the project
Create a proj.cpp file, edit it and make sure it contains the following lines:
#include <windows.h>
extern "C"
BOOL WINAPI DllMain (HINSTANCE hInstance, DWORD dwReason, LPVOID)
     return 1;
This creates an entry-point in the DLL. This function does nothing but is mandatory
to have a DLL after the build of the project.
Add the proj.cpp file to the project as described in Step 2.
Step 4: Choose the target type
At this moment, you can choose if you need a 'DEBUG' or a 'RELEASE' flavour of
the DLL. As there is not much to debug in this DLL, the 'RELEASE' flavour is
recommended. Furthermore, it is much more compact.
Using the Build->Set Active Configuration... menu, choose the Proj - Win32 Release
as the active configuration.
Step 5: Build the DLL
Now, it is time to compile the resource file, compile the C++ file, link both
together and build the proj.dll DLL. This operation is performed by using the
Build->Rebuild All menu.
After a short time, you should see "Proj.dll - 0 error(s), 0 warning(s)" in
the Visual C++ message window. This means that the DLL was built successfully.
Step 6: Place the DLL in the appropriate directory
The proj.dll file is currently located under the c:\MyProjects\Proj\Release
directory. Copy it in an appropriate directory which is reachable in the
runtime environment path.
Part II - USING THE ICON AND CURSOR IN THE FORM
At this stage the DLL is created and can be used in the Form application.
Again, this is a multi-step procedure.
Step 1: Load the DLL in the Forms Runtime environment
Assuming the proj.dll DLL is placed in a directory pointed by the
PATH environment variable, below is the piece of PL/SQL code which loads
the DLL into the Forms Runtime environment. This code can be placed in the
WHEN-NEW-FORM-INSTANCE trigger for example:
declare
     hDLL     ORA_FFI.LIBHANDLETYPE;
begin break;
     --Preload the DLL so the cursor and Icons can be found.
     -- I'm assuming the DLL is in the path here
     hDLL := ORA_FFI.LOAD_LIBRARY(NULL,'proj.dll');
exception
     when ORA_FFI.FFI_ERROR then
          for i in 1..TOOL_ERR.NERRORS LOOP
               message(TOOL_ERR.MESSAGE(i));
          end LOOP;
end;
Step 2: Display the cursor stored in the DLL
Now, you may want to change the cursor when the user clicks on
a specific button. This is an example of code that could be set
in the WHEN-BUTTON-PRESSED trigger:
set_application_property(CURSOR_STYLE,'<proj>TESTCUR');
<proj> refers to the proj.dll. Please note the < and > signs
which are mandatory there. TESTCUR is the name of the cursor resource
as defined in the proj.rc file.
Step 3: Display the icon stored in the DLL
You may also want to change the icon of an iconic button after
some specific end-user action. The appropriate code for that is:
set_item_property('IBUTTON',ICON_NAME,'<proj>TESTICO');
IBUTTON is a PushButton, with the Iconic property set to Yes.
TESTICO is the name of the icon resource as defined in the proj.rc file.

How to use java programe in oracle form

Hello Expert,
My Config is : -
Forms [32 Bit] Version 11.1.1.3.0 (Production)
Jdeveloper - 10.1.3
I want to use the java programe in form builder. I create the one java class in Jdeveloper -
package demo;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
public class get_info{
   public static void main(String[] args){
   ch_add();
   public static void ch_add()
InetAddress ip;
try {
ip = InetAddress.getLocalHost();
/*System.out.println("Current IP address : " + ip.getHostAddress()); */
NetworkInterface network = NetworkInterface.getByInetAddress(ip);
byte[] mac = network.getHardwareAddress();
/*System.out.print("Current MAC address : ");   */
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++)
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
System.out.println(sb.toString());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e){
e.printStackTrace();
and this into Formweb.cfg and default.env and also add into Form_class_path. After that i import this java into forms.

How to use BEAN in an oracle forms at client side

Hello,
I am new in oracle forms.I am using
OS-Windows 7.
Forms [32 Bit] Version 11.1.2.1.0 (Production)
weblogic 10.3.5
Now I want know that how to use bean item in an oracle forms.
Thank You.

Hello,
You copy the corresponding JAR file that contains the Java BEan in your <DEVSUITE_HOME>/forms/java folder, then you add its name to the archive tags of the forsweb.cfg file.
This done, you add a Bean Area to your canvas, set its Implementation Class property with the full class name, then you can communicate with the bean via the GET_CUSTOM_PROPERTY() and SET_CUSTOM_PROPERTY() built-in.
Google could also give you more information.
