How to develop a file dialog box in a oracle forms

please help me its an urgent task,
how to develop a file dialog box in a oracle 6i forms
in html we will use <input type ="file"/> to open a dialog box,so that we can upload file to the server .similarly how to upload a file using oracle.

For Windows there is a library that comes with forms d2kwutil.pll that contains a package win_api_dialog. use the open_file procedure.
NOTE******** when you select a file from whatever windows directory you choose, it will change your working directory to that directory so right after that you will need to reassign your working directory back to what it originally was.
Also, you will need to have d2kwut60.dll in the same directory as your d2kwutil.pll. Both come with Developer.
Example code is
v_runpath := win_api_environment.get_working_directory(TRUE);
v_filename := win_api_dialog.open_file('Find File','C:\','*.*',TRUE, 0, TRUE);
win_api_environment.set_working_directory(v_runpath,true);
Hope this helps

How to Shw Open File Dialog Box

Hi all,
Can anyone help me plz.
I am designing an interface using forms 9i where data entry operator has to insert data for products in the database. Also we want to store the image of the product. so I want to show an open File Dialog box from where user can pick a file and click ok & if it returns the file name with complete path, then i can read the contents of image using read_image_file.
So, is there any Oracle built-in for that???
Thanks in advance

Thanks Ronald webutil worked successfully.
But i am facing following error when i try to go to the Canvas provided by the Webutil setup(olb).
Error is given Below:
1. FRM-13008; Can't find java bean with name 'oracle.forms.webutil.ole.OleFunction'.
Previously it was giving errors on all JavaBean classes then i put the path of webutil.jar file in registry as given in the documention. It works ok for other java beans but why above error is coming.
plz Help.

How can open File Dialoge Box in Oracle9i

can any one tell me how can i open file dialoge box in oracle 9i i am using webutil but when i run this code.. there is an exception during runtime.. not compile time.. so plz tell me how can i open file dialoge box.. thx..
     declare
          file_name varchar2(100);
     begin
          file_name := client_get_file_name(FILE_FILTER=>'TEXT FILES (*.txt|*.txt|');
     end;

Please do not post the same topic in multiple forums. The
only thing I can suggest is when they click on the button to
download, you take flash out of full screen while they download the
video, you can use fileReference to control and monitor the
download. Use a listener object to monitor when download is
complete, then set flash back to full screen.
How are you scripting the full screen?

Open a file dialog box using java

Duncan & Frank or anyone
Can you please tell, or give me a link, which explains how to open a file dialog box using java, and not webutil.
I'm trying to read a file on the desktop and update a database table.
Thanks

See Open File Dialog on the WEB... If you can get me the full version numbers I can tell you your supported position.

Opening a File Dialog Box

Hi,
could somebody help me with how to open a file dialog box.
I have 1 class which has a window with the relevant widgets on it, I want to be able to click a button on the form and pop up a file chooser form then select a file or type in a new filename and then use the selected filename path in the original form to write data out to the chosen file.
i understand that i need to use JFileChooser and it will need to be in a new class (like a dialog box would be).
So basically what i have is 2 classes (the main app and a class called FileOpen.class) so how would i display the fileopen class with the JFileChooser component in it and return what ever is chosen into a string.
e.g.
String fileName = <what would go here?>
kind regards

thats the example filechooser i have working
yet when i try and implement it in my program i just get countless exception errors, im not sure if its because my program extends Jframe and not JPanel
here is my code:-
package as4;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import java.util.*;
import javax.swing.filechooser.*;
import java.io.*;

How do I get back to the newest file dialog box style in LabVIEW?

I have LabVIEW 7.1 and LabVIEW 6.0.2 installed on the same machine. When I doubleclick a .vi file it tries to open in LV602. Of course, if it is a LV71 VI I get an error and it doesn't open. Then I run LV71 and load the desired VI--in this case by using the Open arrow to find it in the "recently opened" list. Now, I've made this mistake before, especially when I don't remember whether I used LV602 or LV71 to create the VI, and nothing bad has happened.
But this time something undesirable did happen: all Open File dialog boxes are of the old funky style. How do I get the file dialog boxes back that I've grown used to seeing when I use LV71?
CLUES:
1. I get the old style dialog box even when I try to open a VI--not just when a running VI invokes it.
2. The built version of the VI brings up the correct, new style, file dialog box--unlike the development environment.
I haven't found any settings in the options area that would appear to affect the file dialog box style. Has anyone ever seen anything like this?

Thanks for the response,
Warren. I think all my problems with LV versions coexisting
peacefully have been related to NIDAQ--and I think the workaround (for
supporting the different levels of LV DAQ VIs--see my response to
Benoit, above) shows that it is not NECESSARY for NI to orphan old LV
versions' DAQ functionality on the development computer, though it is
still painful to be able to have only one version of NIDAQ available on
a given target computer. It's probably a marketting decision
meant to encourage users to stay on the straight-and-narrow upgrade
path.
NI-DAQ has usually been working fine in
several different installed LabVIEW versions on my computer. What is
important is the order of installation. Start first with the lowest
LabVIEW version and install the latest NI-DAQ that supports that
LabVIEW version. Then go to the next LabVIEW version and install again
the latest NI-DAQ version that supported this LabVIEW version and so
on. I'm regularly working with 6.1 up to 7.1 and starting with 8.0
slowly and haven't had real show stoppers yet.

How to create a custom file dialog box/vi (win)??

Hello,
I'd like to create a custom file dialog box to handle the reading of my tdms files. Basicly I want to extend the existing file select dialog box with a graphical preview of the data in the selected file. I know I can create all the logic for file selection by hand and use a list box to display the filelist, but I would rather prefer to somehow use the existing windows controls. So is it possible to get the windows file selector on the front panel of a vi and react to the user selection? If so, is there any example available on how to do this? Any other options? I'm using labview 8.2
thanks for your input!
klaus

Klaus,
I wouldn't know that Microsoft provides access to the controls that Explorer and file dialog consist of.
There might be a different and more powerful solution though. The
WINDOWS Explorer / file dialog have a plugin API that allows you to
associate your own application for thumbnail creation with a particular
file extension. That way, TDMS thumbnails will show in any instance of
Explorer and
File Dialog without you having to make your own dialog. Basically, you
would need to compile the VI that creates the thumbnail into a
LabVIEW-built DLL and then wrap this DLL with some C++ boilerplate code
that Microsoft provides. You might want to have a look at the bottom of
this article to get an idea of how the whole thing works:
http://msdn.microsoft.com/msdnmag/issues/0600/w2kui2/default.aspx.
Hope that helps,

File dialog box: how get full path and filename (firefox 3.0 problem)

Hi,
I have a smilar problem then discussed in this thread: file dialog box: how get full path and filename
Now this solution doesn't seem to work in firefox 3.0,I only get the filename but not the full path.
I have tried to solve this problem by adding *"netscape.security.PrivilegeManager.enablePrivilege("UniversalFileRead");"* in a javacript function but that doesn't do the trick
Although when i tested it local it does work.
Any idees how to solve this?
Best Regards
Stijn

Actually, that is strange and scarry. With 20% of the browser market share they decide to behave like Microsoft did in the past - they want to decide what users need and what they do not need. With 3.0 I have a real problem with some of my applications. They are all tested in IE6, IE7, FF2.0 and they all work the same way (they even work with Opera and Safari). Now, I will for sure not go there and make it work for 3.0, just because 2 out of 200 users use FF3.0. Up to now I have always recomended FF as the best browser. 3.0 causes my opinion to change completely. Competition is always good but it is a question if it is good if we have 20 different browsers out there with equal market shares.

File dialog box: how get full path and filename

Hello All

I want to save full path and filename in the database for creating a link to a file.

\FULLPATH\filename.ppt
but when i save the textvalue in the database or look at the seesionvalue I see
this:
F2087258868/filename.ppt
but I need the full path to create a link. How I can get?
I use version 2.2.1..
Thanks
Putcho

Hi Putcho,
You can create some javascript that puts it into a hidden item.
In HTML Form Element Attributes: onChange="$x('P15_X').value=$x('P15_FILE').value;" Then create another process that stores the value of the hidden item in your own table...
I quickly made an example with a normal text item, so you see it copies itself to the other box: http://apex.shellprompt.net/pls/apex/f?p=286:15

How to add list of multiple file types to file type of file dialog box in LabVIEW

How to add list of multiple file types to file type of file dialog box in LabVIEW?
In file dialog box there is option to add only one file type,in the list,not by seperating commas,
regards,
Naresh.N

Write the file types in pattern Input string, separated by a semicolon ;
For example: *.vi;*.doc;*.jpeg;*.xls
This should return the set of files with matching extensions

How to add array of file types to file dialog box

Hi
I just want to know how to add array of file types in file dialog box vi. I know that multiple file type can be added to filedialog vi in the pattern Input string separated by semicolon (eg *.vi;*.doc;*.jpeg;*.xls). But i want file dialog which is shown in the below picture.
I think that file dialog vi call user32.dll but i don't have that header file to call that dll.
Waiting for your esteemed response.
Thanks & Regards

I'm not sure how (or even if) it can be achieved using the LabVIEW built-in open dialog, but a .NET call to openfiledialog (http://msdn.microsoft.com/en-us/library/system.windows.forms.openfiledialog.aspx) can do what you're looking for. The .NET functions are better documentented that simple user.dll calls, so it might be easier to implement.

How to displays the standard open file dialog box in Oracle Apps Server

Hi,
I am having a form, where i am opening a file and putting that file content in a text box.
This is my code written in WHEN-BUTTON-PRESSED trigger:
declare
in_file Text_IO.File_Type;
linebuf VARCHAR2(8000);
filename VARCHAR2(30);
BEGIN
filename:=GET_FILE_NAME('d:\Rajesh\Practice', File_Filter=>'Text Files (*.txt)|*.txt|',select_file=>false);
in_file := Text_IO.Fopen(filename, 'r');
LOOP
Text_IO.Get_Line(in_file, linebuf);
:text_item5:=substr(:text_item5||linebuf||chr(10),1,5000);
END LOOP;
EXCEPTION
WHEN no_data_found THEN
Text_IO.Put_Line('Closing the file...');
Text_IO.Fclose(in_file);
END;
I have posted this in ORacle Apps Server.Where i was not able to get the Open Dialoq Box.It is giving an error as
"FRM-40735:WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-302000.".
I think the GET_FILE_NAME function is not supported in the Apps Server.
Is there any alternative solution for getting the OPEN DIALOG WINDOW in Oracle Apps Server?
Pls let me know.

A call to the file dialog box will call a modal system dialog. So LV can't go on executing VIs in the user interface thread."
Are you sure? I think, that File Dialog, called by LabVIEW File Dialog from Advanced File Functions Palette doesn't blocking any cycles in subVI, which running in UI Thread. Look in my old example (that was prepared for other topic, but may be good for this topic too).
2 linus:
I think, you must a little bit reorganize you application for to do this. You must put your File Dialog into separated cycle. This cycle, of course, will be blocked when File Dialog appear on the screen. But other cy
cle, which responsible for visualization will run continuosly at the same time...

How to incorporate File name and timestamp automatically into select and save file dialog box?

Hello,
i am trying to incorporate the file name which is inputed by the user along with the timestamp into the selected and save file dialog box. Can you help?
Thanks
Solved!
Go to Solution.

You can pass a default file name to the 'File Dialog' Express VI.
Use the 'selected path' output to open the file.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T
If you don't hate time zones, you're not a real programmer.

How to trigger an "open file" dialog box

I am using forms 10g. Does anyone know of codes to trigger "open file" dialog box in a button object?
My goal is that the user may be able to select a file from his terminal by clicking a button.
Thanks in advance.

As aweiden suggests, there are additional setup steps that have to be completed on your workstation as well as the Forms server so you can use the WebUtil library. If you are using Forms 10g R2, then I recommend you conduct a search of the Forms Help system (Search tab) on "WebUtil" and select the "Configuring WebUitl" topic. If you are on Forms 10g R1 (9.0.4), then you had to download and install WebUtil on your workstation. I recommend you read the Web_Util.pdf in the "DOC" folder an follow all of the steps in Chapter 2 : Configuring WebUtil.
