HELP - scrollbar
Hi,
I have a problem with an overlay: I can’t apply the scrollbar on buttons.
I can apply a scrollbar for a group picture. However, the touch user will roll continue all images.
I'd like to just scroll to the next image, from image to image.
How can I do it on DPS? I saw this effect on WoodWing.
Best Regards,
Your question is not clear at all. It’s obvious that English is not your native language so either find someone with a stronger command of English or post in your native language and we’ll see if we can figure it out that way.

Closing the browser after logout
Version 1.6
We're using Internet Explorer and I need to close the browser after/when the user clicks on the Logout link. How can I accomplish this?
Thanks,
JoeThe online help for the onClick Javascript field says
"In the link generated for this icon include the following onClick javascript. Use of the onclick javascript could popup a help page in a new window (see example 1).
Example 1:
window.open('US/asfhhome.htm','Help','scrollbars=yes,resizable=yes,width=625,height=350,left=25,top=150');return false
Set the Icon Target attribute to # if you are using OnClick JavaScript. Set the Image Alt Text attribute to the text the user will see to click on."So, try putting "#" in the Target and window.close() in the onClick Javascript box.

In a report, select the column which can link to a query information
Hi,
I want to open a report in which there is a column, say, Name, when I click it
I can view the other information about this Name, say, address or contact telephone no.
Regards,
Simon WongHi,
1. Go to any report with link column to a form. It is a very common situation.
2. Go to the link column Column Attributes/Column Link/Target and change it to URL.
3. javascript:popupURL('f?p=&APP_ID.:205:&SESSION.::&DEBUG.::::YES','Help','scrollbars=yes,resizable=yes,width=625,height=350,left=25,top=150');
4. Replace 205 (It is my page number) with the number of the page which you are working on.
5. Apply/Apply/Run the page.
6. You should see the printer friendly version of your page in separate window without loosing original one.
This is a very simple, easy to use and understand example.
You can replace “205” with any report showing Address … for the client.
Good luck!

How to open a new browser window from a link on the navigation bar
Hi,
I entered a URL in the 'URL Target' field for the Navigation Bar Entry. As expected when the I clicked on the link in the Navigation Bar my browser refreshed with the target URL.
I want to be able to actually open a new window rather than refresh my current window. The help text says, and I quote ...
"In the link generated for this icon include the following onClick javascript. Use of the onclick javascript could popup a help page in a new window (see example 1).
Example 1:
window.open('US/asfhhome.htm','Help','scrollbars=yes,resizable=yes,width=625,height=350,left=25,top=150');return false
Set the Icon Target attribute to # if you are using OnClick JavaScript. Set the Image Alt Text attribute to the text the user will see to click on."
So I created similar Javascript as to the example and placed in the 'OnClick Javascript' field, and placed a '#' in the 'URL Target' field.
When I run it doesn't work, the '#' is picked up and the Javascript is ignored. Can somebody please tell me what I'm doing wrong.
ThanksI had the same problem. I finally ended up just using the standard popupURL javascript. In the URL Target I have:
javascript:popupURL('<link>')
This opens a new window but since it is for popups the menus are missing. You may want to write your own javascript function to open the new window with your own settings.
Search the forums for popupURL for more ideas.
javascript:popupURL()

Report field substibution on URL Redirect
I am using ApEx 2.0
I have a page with two report regions based on SQL queries, joined by a common column. The master region is read only and in detail region, I changed the attribute of one field to display as text.
So, for example, the Master region has two columns:
M_COL1, M_COL2
The detail region has 3 columns:
M_COL1, D_COL1, D_COL2
The regions as joined on M_COL1 and D_COL2 is the Text field.
Next, i added a button to this detail region. When clicked I want this button to launch a URL whose parameters are sourced from some of the existing report column/fields on this page.
I cannot seem to get the substitution to work in the URL Redirect field of the button definition.
I want something to the effect of :
http://someserver:port/some_path/something?param1=&M_COL1¶m2=&D_COL2
I tried putting #M_COL1#, :M_COL1 etc. but it doesn't work.
Any ideas/pointers?
Thanks,
ManishHi,
5. Pop-up reports:
- Go to any report with link column to a form. It is a very common situation.
- Go to the link column Column Attributes/Column Link/Target and change it to URL.
- javascript: popupURL('f?p=&APP_ID.:205:&SESSION.::&DEBUG.::::YES','Help','scrollbars=yes,resizable=yes,width=625,height=350,left=25,top=150');
- Replace 205 (It is my page number) with the number of the page which you are working on.
- Apply/Apply/Run the page.
- One would see the printer friendly version of ones page in separate window without loosing original one.
This is a very simple, easy to use and understand example.
One can replace “205” with any report showing Address … for the client.
6. One Master and many Detail tables:
Suppose that there are relations One to Many between one master and two or more details tables.
One can use two regions on a page. One should be a form region for the master table and second one should be a report region with several links.
6.1. Create a view of those two or more details tables. That is one master and one details view.
6.2. Create a Master Details form. The details form should be one of details tables.
6.3. Go to Edit Region (Details Region) and change SQL Query (updatable query) to SQL Query.
The Details form became Details Report.
6.4. Change Report Region Source from details table query to the view query.
6.5. Duplicate columns which are links and reorder them. Replace their header names with “ ” for instance.
6.6. Into Column Attributes/Column Link/Link Text pick an icon.
6.7. Select for Attributes/Column Link/Target “URL”.
6.8. Into URL field type
javascript: popupURL('f?p=&APP_ID.:205:&SESSION.::&DEBUG.::::NO','Link','scrollbars=yes,resizable=yes,width=625,height=350,left=25,top=150');
and replace 205 with the appropriate page number.
Now the page has one form with Next and Previous buttons for the master table and one report for the Details view with two or more links. Pop-up window with an edit detail table form appears when one click on a link (icon).

Closing seperate browser after cfcontent
Hi all,
I would like to get some help on cfcontent.
I use cfcontent to open a pdf in a seperate browser,
which works.I have a close button on the parent
window, along with other information related to the document.
When I hit the close button, I would like the pdf
browser(window)
to close. It doesn't seem to recognize that the PDFImage
window is open.
Below is my code to display the image
<cfheader name="Content-Disposition"
value="#URL.Image#">
<cfcontent type="application/pdf" file="#URL.Image#">
//Code to close the image window in the parent window close
button.
function closepage(){
//one way
if (window.PDFImage && window.PDFImage.open
&& !window.PDFImage.closed){
window.PDFImage.close();
//other way
if (PDFImage != null && PDFImage.open){
PDFImage.close();
The next issue is, I am trying to display a jpg in a
<table, the image must
be within the table. It works when I have the <img tag,
but I Would
like to replace it, due to some sharing violation of the
image being displayed.
cfcontent seems to work, but it takes the whole browser,
other codes(like buttons)
are ignored.
<table align="left" cellpadding="0" cellspacing="0"
class="withborder">
<tr> <td><span id="List3">
<cfheader name="Content-Disposition"
value="#Form.image_file#">
<cfcontent type="image/jpeg" file="#Form.image_file#">
<!---<img border="2" id="img1" src="#Form.image_file#"
width="250">--->
</span></td>
</tr>
</table>
I am using MX 7. Any suggestions/solutions are welcome.
Thanks all for your time.The online help for the onClick Javascript field says
"In the link generated for this icon include the following onClick javascript. Use of the onclick javascript could popup a help page in a new window (see example 1).

Help Needed With Scrollbar and Content
I'm having a difficult time with the Scrollbar component. I'm trying to have a scrollbar set up to navigate a text field or a MC of a text field. I managed to get it functioning within the desired frame, however when I jump to another frame, that very same content appears on the other frame, despite the fact that said frame did not have the scrollbar nor the content pasted within.
The bar seems to do what I want it to do save for the unwelcomed presence outside of the frame of choice. Here's the code I'm using. This is the keyframe code:
import boppreh.ui.Scrollbar
var scrollbar1:Scrollbar = new Scrollbar(boomboom, 500, true, false, 293, bar, slider, arrowUp, arrowDown)

public void actionPerformed(ActionEvent e)
FileInputStream fis = null;
if (e.getSource() == add) //The ADD button.
//User has not populated all the input fields.
if(name.getText().equals("")|| address.getText().equals("")|| phone.getText().equals("")|| sex.getText().equals("")|| dob.getText().equals("")|| photo.getText().equals(""))
JOptionPane.showMessageDialog(null, "Please fill in all the fields","Missing Fields",JOptionPane.INFORMATION_MESSAGE);
else
// save the new customer:
try
//1. take the customer's data and photo:
int userId = Integer.parseInt(id.getText());
String userName = name.getText();
String userAddress = address.getText();
String userPhone = phone.getText();
String userSex = sex.getText();
String userDateBirth = dob.getText();
String photoName = photo.getText();
String audioName= audio.getText();
File file = new File(photoName);

Browser scrollbar and Flash scrollbar ? I need help!
Now I have a problem about the scrollbar:
The height of my swf file is longer than browser height, so
the scrollbar of browser's occurred, if I scroll my mouse wheel,
the whole flash roll down, but the problem is that I have used a
scrollPanel component which write by myself, and in this situation,
when I scroll the mouse wheel, the scrollbar in flash and browser
will both in effect.
The question is that how to disable the brower scrollbar when
I scroll mouse wheel inside the scrollPanel component. In fact,
adobe already done this, if my cursor inside a textfield object,
the scrollbar of bowser will not get focus. How to achieve this
effect? My english is bad, but I need help!i recently downloaded trails of flash cs4 and web premium package cs4 (took a day to download at high speed starbuck's internet). couldnt get the setup.exe to work or the uninstaller to work. surfing tech support over next couple weeks to try various agents was useless and expensive until i finally reached someone with useful info. all the agents had foriegn accents and read from scripts and web support pages until yesterday, when i reached a guy who told me two things i'll report to various forums addressing this same issue:
1. download windows uninstaller program from their website (google: windows ininstaller). this program is different from the one that doesnt work in the programs and features area of control panel when you try to uninstall adobe products from there.
2. windows explorer 8, the newest version, DOES NOT download adobe softare properly and leaves things out, causing all sorts of issues including the setup.exe program not working. download firefox browser from mozella (google: firefox) and use it for all adobe downloads. apparently the old windows explorer 7 will work, but if you already have explorer 8 installed its easiest to just use firefox.
i'm spending the next couple days downloading the 4.14 G web premium trail with firefox and will report if this works. -
Hello.
I am trying to build a webpage with a fixed sized window in
the centre of the page. Within this window I would like to display
some photos I have taken. What I would like to happen is for people
to be able to scroll right to view my pictures, but for the main
navigation not to disapear. So I thought I could incorporate a
horazontal scrollbar into the central box, so that whatever content
is in the box is scrollable. I have noticed things called div tags
and I think that this is the way forward, although I don't seem to
be able to use these effectivly.
Can anybody help me please.
Thanks
SThe scrollbar works, you can try using a simple JComponent with a set preferred size instead of the JTextPane and it will work. The problem is that the JTextPane always wraps its lines, so it doesn't need to be wider - therefore the scrollbar doesn't appear (or doesn't display the knob in case it's always displayed). You'll have to find a way to somehow disable line wrapping in that JTextPane, or you'll have to use another component to display your data, for example JTable.

Browser scrollbars appear by default in all pages requiring them. You don't need to do anything to make them appear. I don't think you understand Fixed positioning well enough to be using it so much in your CSS. It has a purpose but probably not what you think.
See position:fixed sticky text demo.

Need help creating horizontal scrollbar in graphic timelime (built in AI)!
I am trying to use Catlyst to build an interactive scrollbar on a graphic timeline build in Adobe Illustrator, I want to be able to scroll from one end of timeline to the other. Can anyone help? Thanks!
Can you post a screenshot of the timeline you are trying to convert. It will help in accurate response.
You would probably need to do it in two step:
- Have the graphic timeline converted into Datalist element, and make the data repeatable.
- Create a Horizontal Scrollbar component and add it to the datalist component (timeilne)
- If you have the Horizontal scrollbar designed, then select it and convert it to a Horizontal Scroll component (using the HUD - the black overlay that comes up when you select a graphic element)
- After conversion you would need to define the parts of the H. Scrollbar (Track, thumb, right button, left button). Note: It helps if you designed your H. Scrollbar with these components in AI/PSD.
- Now come back to the artboard, and select the H. Scrollbar by clicking on it.
- Cut the H. Scrollbar
- Click the Datalist element, and go to Edit Parts (in HUD)
- Paste the H . Scrollbar inside the Datalist element. This will attach the scrollbar to the data.
Hope this helps,

Tutor 14.0 Problem - Please help! Vertical scrollbar missing
I recently upgraded from Tutor 12.2 to Tutor 14.0.
When I publish the Desk Manuals for each actor, the html page does not have the vertical scrollbar, and you can't access the documents that are at the bottom of the list.
Has anyone experienced this? Is there a fix for this? I searched for patches in Oracle Support but could not locate any.
I tried to troubleshoot this by replacing the tutor.css files and tutor_script.js file with those from 12.2, but that didn't work. Is there another file that controls the output of HTML files when you publish through Tutor Publisher?
Please help!
Thanks!Ok i am sorry about giving the wall paper here is to more precise problem
