    public ImageDownloadTestScreen() {

        ButtonField btnDownload = new ButtonField("Download Image", ButtonField.CONSUME_CLICK);
        btnDownload.setChangeListener(new FieldChangeListener() {
            public void fieldChanged(Field field, int context) {
                String url = "http://worldwide.blackberry.com/blackberrycurve/8900/8900_series_device.jpg";
                label.setText("Start to download...");

How to download the image of the BLOB, inline in new browser tab or window

APEX V4.2.3
I have an interactive relationship with a column of type blob download which is the inline value. When I click on the link 'Download' the image automatically appears in the same window as the application of the APEX. How do I download the image in a new tab in the browser? I need to shake "target ="_blank"' somewhere but I don't know where that link structure is hidden."
Here is the code for my download section in the interactive report.

Select

....,

decode (nvl (dbms_lob.getlength (BLOB_CONTENT), 0), 0, null,)

"< img style =" border: 4px solid #CCC; " -moz-border-radius: 4px; -webkit - border-radius: 4px; » '||

Download the image file from the server

Hi I want to download the image file of the server.
When you download a file save dialogue comes. I don't want this dialog box.
There will be a specific location where this file is saved.
Can someone help me?

You can not download the file without saving dialog file - it is a security restriction.

Alex,

There will be no default URL that allows you to view the downloaded images. You will need to do something yourself to make the image visible via a URL; some suggestions would be:

(1) on the Web/Application Server, create a virtual directory to d:/uploads/logo map
(2) write your own servlet that can (according to certain parameters you offers in the URL) read the file from the image of the directory and the return flow to the browser

Download the image to the directory and database of the same form data
Hi all

I play to build a shopping cart (never done before) a tutorial of Gordon Knapp at www.webthang.com.

I created the site and it works perfectly. Now, I want to extend it.

There is a form that allows the user to add data to the database. I would also like to be able to transfer an image to a directory on the server and add the data to the database at the same time of the same shape. It would be good if the input field "< input name ="product_picture"type ="text"id ="product_picture"tabindex ="6"size ="50"/ >" could be filled automatically by the file name of the image being downloaded, but it's not a neccessity.

I looked at different packages ASP Upload and I can upload a single image, but none of them clearly show how to download the image and add data to the database at the same time.

It is a private project I need suggestions for free.

The tutorial shows how to create Dev Ultra site but works perfectly well in DW. The page looks like this. It is named "admin_add.asp":

"< %@LANGUAGE="VBSCRIPT "CODEPAGE ="65001"% >

How can I make the quiz button download the image appear?

Hello.
I am trying to replace the button 'Submit' I use in a quiz, but the button to download a new button does not appear. Here is a screenshot so you can see what I mean:
The button normally appear to the right of the drop down list 'Button Type', but is no longer. I tried the following hotfixes, which none have worked:
-Resizing of the window
-Closing and reopening of Captivate
-Clear cache project
-Remove temporary files
-Deletion of the folder, preferably
Any thoughts on what I can do? Because there is a "submit" button quiz, I'm unable to download the button image and use a place-clickbox.
I use 7 Captivate.
Thank you.

The Send button is an embedded object (has no separate scenario) all quiz slides, the most important of them because you should never delete to avoid the screwing of the functionality of the Question slides.

You don't say HOW you tried to achieve this goal? You can check the style of the buttons of the Quiz in the Style of the object manager?

Another solution would be to use an image and do the quiz button style so that it is invisible (no label, no fill, no stroke). To output SWF button will remain active.

When I long press on and record an image it goes to my downloads, the image is stored on my phone? or app only?

The image does not appear in the Gallery of my phone, but I can see in the download section of the application. Let's say that I want to record and mms image rather that the share link, is it not possible?

Oh, and it is not a plugin problem, because I have installed "Personas" and has done after the image.

The image is saved on the SD card, but it does not appear in the Gallery right away due to a bug in Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=646550

This bug will be fixed in Firefox 5, which will be published in about two months. If you want to help test the difficulty today, you can download a version of Firefox 5 Overview ("Aurora") of https://wiki.mozilla.org/Mobile/Platforms/Android

Many times you don't need drivers. The camera will appear as a memory device USB. You can simply open in WIndows Explorer and copy the images to your hard drive.
