Render CFM to string

Hi,
I have the following need. I am building a webservice that
needs to be deployed in some machines. I would like the client
machines to have very little to do with the processing of forms.
All the client does is invoke the webservice and it should return
the forms and validation.
Well, I have an app working well with cfinvoke method=....
however, I would like to make this work as a webservice too.
So, I suppose I need to be able to return something to the
client. However, I have come to learn that <cfinvoke .. doesn't
return anything to the client (as it should). The only thing going
back to the client is the returned variable.
So, I need to do all rendering a cfm into a string object
that I can return back to the client.
I just don't know how this can be done.
My other solution is to copy all the html + scripts from cfms
and put them in the cfc and add quotations. Well, That's not a bad
idea. But that's a bit silly if I have to copy the javascript
libraries and so on.
Any ideas on the matter are greatly welcomed,
Roland

I'm not 100% clear on what you are trying to do, but I think
the
<cfsaveContent...> tag could do what you need.
<cfoutput>
<cfSaveContent variable="foobar">
<html>
<head>
<title>A Test</title>
</head>
<body>
<p>#dateFormat(now(),"dd mmmm yyyy")#</p>
</body>
</html>
</cfSaveContent>
</cfoutput>
<cfoutput>#foobar#</cfoutput>

Can I render facelet to string in memory ?

Hi,
I've been working on porting an existing asp.net web app to a facelets based solution, and there is a particular method which is used quite frequently in the asp.net project. A component, with an ascx extension is loaded dynamically, and rendered to string, which is later either passed via ajax calls or used for decorating a portion of a page.
Is it possible to render facelet composite components like this? Like passing a pojo to a composite control and rendering the output as string?
Kind regards
Seref

Hi Nick,
That's a valid suggestion for the LabVIEW developers (post it using the "feedback" link on ni.com/contact), but I'm afraid that it would invite customers to mess up things by not keeping references in a short leash and closing in the right order when done.
In case you want the closest to this kind of feature, try the Request Deallocation function and place it inside the VI that holds the references. When that VI finishes and returns to the caller, all unused memory will be deallocated.

SSRS 2012 Print Error w/ Win 8.1 IE11 (0x80004005)

I'm having an issue printing SSRS 2012 reports from Win 8.1/IE11. When I print I get "An error occurred trying to render the report. (0x80004005)" See below for SSRS Log. This happens when trying to print any reports from this
server on a win 8.1 machine. I've checked on Win8/IE10 and Win7/IE11 and they both work fine. When I change the "User agent string" in F12/Emulation to IE10 instead of default it also works fine. These reports are in compatibility mode
by default due to the "Dispaly intranet sites in Compatibility View" being checked by default. If I uncheck this box the reports will not even run. They display an error message of "Value cannot be null. Parameter name: String"
which is very similar looking to the error in the log below.
TIA for any help
Tommy
The error log from SSRS is

Hi Joshua.Arenz,
As per my understanding, you configured SSRS 2012 of SharePoint mode, when you click system setting in Central Admin, you got the error message.
According to the error message, the Reporting Services service application is not configured correctly. Please make sure you created service application correctly by following steps:
In SharePoint Central Administration, in the Application Management group, click Manage Service Applications.
In the SharePoint toolbar, click the New button.
In the New menu, click SQL Server Reporting Services Service Application.
In the Create SQL Server Reporting Services Service Application page, enter a name for the application.
In Application Pool section, create a new application pool for the application (recommended). Then select or create a managed account for the application pool.
In the Database Server, you can use the current server or choose a different SQL Server.
In Database Name the default value is ReportingService_<guid>, which is a unique database name. If you type a new value, type a unique value.
In Database Authentication, the default is Windows Authentication.
In the Web Application Association section, select the Web Application to be provisioned for access by the current Reporting Services Service Application.
Click OK.
For more information about Creating a new Reporting Services Service Application, please refer to the following document:

If you have any more questions, please feel free to ask.

Error while Exporting large data from Reportviewer on azure hosted website.

Hi,
I have website hosted on azure. I used SSRS reportviewer control to showcase my reports. while doing so i faced an issue.

It works locally (developer machine) or having less data. But it didn't work with large data when publish on azure.
Any help will be appreciated.
Thanks.

Sorry, let me clarify my questions as they were ambiguous:
For a given set if input, does the request always take the same amount of time to fail? How long does it take?
When it works (e.g. on local machine using same input), how big is the output file that gets downloaded?
Also, if you can share your site name (directly or
indirectly), and the UTC time where you made an attempt, we may be able to get more info on our side.

R183 System Update - Scheduled to go live January 22nd, 2013

We are announcing a new Business Catalyst release, scheduled to go live on January 22nd, 2013.
Please refer to our official blog post for feature highlights and other major improvements slated for this release.
Minor enhancements and cosmetic improvements
Grid state persistence - with this release, most of the item lists displayed in the new admin user interface will remember the page and the sorting applied on a list when returning from a detail page
Edit page properties in the new file manager - when editing a page in the new File Manager, users can now edit the page properties like SEO metadata, workflows, or page visibility
Updated Email Marketing wizard - we have simplified the email campaign wizard and merged the Type and Details step into a single one, updated the controls for setting up one-off and loyalty campaigns and moved the Email Campaign subject into the content tab
Secure domain redirects - starting with this release, all sites will have this feature turned on; if you redirect users to external websites, you should add those into the Secure Domain Redirect list
SPAM improvements - comment workflow emails are no longer sent when a comment is marked as SPAM
Limit the comment size - Starting with this release we will be limiting the number of characters per comment to 4000
URL Redirects have been moved from Page Details into Site Settings menu
Display how many subscribers are into a Secure zone in the secure zone list view
Renamed Advanced View tab from pages screen into List View and made it default for new sites
After sending a Campaign, don't show an error when redirected to the Stats tab
Site Manager > Pages - Advanced view buttons don't have the same height. Might be reproducible in other screens as well.
Updated styling for Find a Customer link found in some CRM screens
Updated styling for date picker in filters
Fixed icons alignment in the left menu + redesign some icons to be more relevant to the menu entry
Fixed footer spacing in some screens (it's not always the same)
Page status (draft/live) was sometimes shown in grey
Table list headers font-size is not the size in specs (all over the UI)
Consistency improvements for links color (we had 5 different tones of blue, now we have just one as in specs)
Site Manager > Page Details - Breadcrumb has the correct caption Pages instead of Web Pages
Web Forms field categories wrap on the second line when the window is resized although the screen is optimized for low resolutions screens.
Wizard tabs have different colors depending on the screen.

Issues:
1. The ecommerce Stock attribute beta is live with the bugs reported in beta. Including the main one where if you have products with stock attributes, despite them rendering in the export file you can never import products back into the system because of stock sku features. Deleting all products allows you to upload with all sku information as a work around but on some uploads stocks are reset to 0.
2. Intermintant permission issues creating folders that have same name as web apps.
3. Can not make folders in BC editor (under develop) that are existing web apps
4. If you move a pre existing page via FTP into a new created web app folder and rename it to index.html It will not work. In the admin it has no file extension so you have to add it there.
5. Just had it confirmed by live chat support who replicated it on a demo site. Securezone update details form with custom CRM fields.
CRM fields will render current data but will not update the custom CRM fields in the crm on submission of the form.

How to use ZoneView in a JTextArea or JTextPane?

i would like to view an large file (25MB with about 600.000 rows) in a JTextArea or JTextPane. As I know the JTextArea creates for each line of the document at least one object, due to this fact it consumes about 330MB (for the file mentioned above) of memory and is useless. Now i found the ZoneView/AsyncBoxView for displaying and consuming memory only for the zone which has to be displayed. But how can i use the ZoneView in a JTextArea? Any examples?
Thanx,
Oliver

Hi Folks:
I would like some examples of using ZoneView as well. I read 1Mb files and convert them to strings and them attempt to render that entire string onto a JTextPane. As I understand it, ZoneView will improve the time to render the string on the JTextPane.
My code is something like:
final String fileToString = readInput();
textPane.setText(fileToString);
//readInput() is a file reader method
The files (or strings) have upwards of 1000 lines; this takes a coupla minutes to render on a text pane.
Hopefully they will post an example of ZoneView soon. Or maybe put it on the Question of the Week?!

Play a specific part of a timeline

I found this topic which is really close:
Play a specific part of a timeline
I have 4 objects sitting in a circle. Similar to a compass. When I click on one of the objects, it should move in a circular path to the topmost position (north). It can go clockwise or counter-clockwise (whichever is closer) in order to get to the north position.
I was using labels and can use play("symbol_name") to start at the right time. but if I follow that command with stop(X) where X is a point on the timeline, it immediately jumps to that point instead of traveling the timeline to get there. It basically ignores the circular animation and jumps to the final destination.
I can't put stop() on the timeline as a trigger because an object may need to pass over it. For example, I want to move object 1 from point A to D (skipping B and C). If I had stop() triggers at B and C, I could never get the animation to play from A-D.
BTW the objects are grouped together as a symbol and so when I click one of the objects, I am actually rotating the parent and then rotating its children the same amount in the opposite direction.
Any suggestions? Thanks.

Thanks Vivekuma,
I have uploaded the project here:
edge3.zip - Google Drive
Only the clock, people and the monitor icons have click behaviors now. As a reminder, the goal is that when I click on an icon, I want it to rotate to the north position (choosing clockwise or counter-clockwise depending on which is the shortest route).
It's working on the first click with the monitor icon (by first click I mean after a screen refresh). But on first click with the clock where I am using playReverse, it plays to the next trigger and then and then does a play (not reverse). I think that is because it gets to the trigger and then I am issuing a play command instead of continuing the existing playReverse command. So instead of a play command at each trigger, I guess what I need is a "continue" action that just allows it to keep going. Is there such a thing?
Also, notice this: refresh, click the monitor and then click the monitor again. The first click should take it to the north position. Clicking again should just stay there but instead it goes to the home position.
Lastly, is there a way to render a type string on the page that just shows the current position (time and label)? Thanks,
Mat

Wordwrap nodes in jtree

Anyone know how we can do wordwrap of nodes in jtree?
Please help...
Thanks.

Any example on this? what html code should I use? The simplest possible, eg
yourNode.setText("<html>" + yourNodeText + "</html>");Most JComponents can render this html string and produce a good result. But if you wanna get a little more complex and use styles and other web things, then do as said, (two posts above) and use a JEditorPane specifically for cell renderer

Hiding POSTed parameters in v2

Hi:
I have a portal which contains tabbed pages. My problem is that within those tabbed pages I have jsp portlets which contain forms. When I submit the form, the data gets posted correctly, but when I change to another tabbed page, all the form variables are submitted in the URL to the new page. How do I prevent POSTed form variables from being added to the URL??

When I press the submit button, the transient parameters are passed, but when I refresh the page the transient parameters are also passed.
When I make two TAB pages in the portal, and navigate between them, the behavior is the same.
Here is my URL after opening the tab page in a new navigator window:
http://portal2.eurotrend.hu:7777/portal/page?_pageid=73,31262,73_35033&_dad=portal&_schema=PORTAL&Amount=50&Action=Transfer
You can see the transient parameters in the URL!
I click the tab after submit.
This happens in IE 5.5 and IE 6.0
Thanks in advance!

[Formatter2] XExpression in a single line only

Hi,
My language is derived from XBase and and its formatter is thus derived from XBase formatter.
The only difference is that I want XBase expressions to hold on a single line
and remove the support of multiline.
Overriding all the methods from the XBase formatter would be very tedious and generate a lot of redundant code.
Anybody knows an elegant/working method to achieve that ?
Thank you.

And the code to render to a String (you need Guava):
static class TextReplacementComparator implements Comparator<ITextReplacement> {
override compare(ITextReplacement o1, ITextReplacement o2) {
if(o1.offset<o2.offset) return -1
else return 1
def String getFormattedEObject(EObject eobject, extension IFormattableSubDocument sfd) {
val txt = eobject.regionForEObject.text
format(eobject, sfd)
val replacements = sfd.renderToTextReplacements()
Collections.sort(replacements, new TextReplacementComparator());
var inFormattingText = txt
var adjustment = 0
for (ITextReplacement itr : replacements) {
val replacingText = itr.replacementText
val replacedText = itr.text
val oldOffset = itr.offset - eobject.regionForEObject.offset + adjustment
inFormattingText = FormattingUtils.replace(inFormattingText,oldOffset,itr.length,replacingText)
adjustment = adjustment + (replacingText.length-replacedText.length)
return inFormattingText
//return FormattingUtils.removeCRLFTs(inFormattingText)
}

How to see multilanguage data in forms9i

Dear All,
I have installed 9i Developer Suite & 9i database in the same machine.our application has to display multilanguage data like malay,chinese and english.our database is character set is AL32UTF8. Also I have set NLS_LANG=AMERICAN_AMERICA.UTF8 in associate home (In the Regedit both client & server home)
I have create the table which has datatype varchar2 & nvarchar2. Also I have inserted chinese character into
both columns based on this table . Now i have created the sample form after running that form against web.i couldn't see the data in their chinese languages. I am able to see only junk data (some square boxes).basically 9i we can run only against web. for that Even i have set it NLS_LANG = SIMPLIFIED CHINESE.ZHS16GBK in the \oracle\orad2k\forms90\server\default.env file. Also In the default browser I have given
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">.Still i could not see the chinese data.
What should i do to see the data in their chinese languages. Please help me it is very very urgent for me.
Thanks in advance

Hi,
actually if you see data garbaged then this points to a wrong character set used for the application. on the Web Forms9i uses the NLS setting that is defined in the default.env file in the forms90/server directory. Since you only can set one NLS parameter you should look for a character set that can render all language strings you use.

G.drawString and increase character offset?

Can I modify the character offset value being used in g2d.drawString method?
I want to have more space between characters in a string.
I've tried Google and JavaDoc to find a solution, but failed.

        f.getContentPane().add(comp);
        f.setSize(720,300);

Emulation of browser font rendering metrics

I am completely new to using java2d. I need to determine where a string rendered on a windows browser (e.g., IE) in a known font in a known width would line break, and also how much vertical space it requires to render the entire string. Obviously, this is based on certain assumptions, such as the user leaving "text size" in the default setting in the browser.
I have run some experiments to understand this. First, I wrote a small HTML file to use as a benchmark:
<html>
<body>
<table cellspacing="0" style="margin:0px;padding:0px;">
<tr>
<td style="vertical-align:top;width:600px;">
<p style="margin:0px;padding:0px;font-family:arial;font-size:10pt;">
aa ab ac ad ae af ag ah ai aj ak al am an ao ap aq ar as at au av aw ax ay az
ba bb bc bd be bf bg bh bi bj bk bl bm bn bo bp bq br bs bt bu bv bw bx by bz
ca cb cc cd ce cf cg ch ci cj ck cl cm cn co cp cq cr cs ct cu cv cw cx cy cz
da db dc dd de df dg dh di dj dk dl dm dn do dp dq dr ds dt du dv dw dx dy dz
</p>
</td>
</table>
</body>
</html>I found the following code and ran it just to see what it would do, using the HTML file shown above:
// HTMLExample.java
import javax.swing.*;
import javax.swing.event.*;
import java.io.*;
public class HTMLExample
    public static void main(String[] args)
        JEditorPane pane = null;
        try
            pane = new JEditorPane("file:///C:/browser.html");
        catch (IOException ex)
            ex.printStackTrace(System.err);
            System.exit(1);
        pane.setEditable(false);
        final JEditorPane finalPane = pane;
        pane.addHyperlinkListener(new HyperlinkListener()
            public void hyperlinkUpdate(HyperlinkEvent ev)
                try
                    if (ev.getEventType() == HyperlinkEvent.EventType.ACTIVATED)
                        finalPane.setPage(ev.getURL());
                catch (IOException ex)
                    ex.printStackTrace(System.err);
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setContentPane(new JScrollPane(pane));
        frame.setSize(600, 400);
        frame.setVisible(true);
}Not impressed, looks nothing like IE rendition (or FireFox, which looks the same as IE). The font is way too small.
Then I found some code that uses LineBreakMeasurer. I don't really need to render anything, just to understand the specifics of where the string would break and how tall the bounding box is for the lines that have been broken. Again, remember that I am new to this, but I found that if I want to render a 10pt arial font that appears the same size as text rendered in the browser, I have to specify 13pt. The horizontal width for breaking the lines seems to need no such adjustment. However, I did notice a slight difference in character widths and a definite difference in line height/spacing. The following code is my variation on an example I found to illustrate this.

Question: I need [i]exactly to emulate the browser's breaking and rendering of text without actually rendering the text. The information I need is:
- where in the string are the line break points (this code finds those)?
- what will the height (in pixels) be of the rendered lines?
Any help is appreciated.

Somehow the p tags got lost in the HTML example. The first line after the td is the <p style=. And then after the content, there is supposed to be a closing </p>I had to do HTML escaping to show this.

Can I install Coldusion Developer Version and XAMPP on the same computer?

I'm trying to teach myself ColdFusion and I need a testing enviroment to play around in.
I already have XAMPP installed on my computer. Do I need to delete XAMPP in order to install ColdFusion locally?
Thanks.

Hi,
It's great that you're learning ColdFusion, you can install ColdFusion without uninstalling XAMPP. You can select the built in port to install ColdFusion which is default 8500 incase this port is already in use it can detect the next available port. Once you will install ColdFusion you can use ColdFusion webroot to render cfm pages.
Hope this helps.
Thanks,
Priyank
