In my Metro app, I have some code that builds up a TileWidePeekImageCollection06 (I assume this question applies to TileWidePeekImageCollection05, too), as shown here.
If I supply 6 images, then the sixth is shown in the "peek" along with the text, if I supply 5 then it looks like the fifth is shown with the text. However, if I supply less than 5 images, I can't seem to determine which is shown.
What are the rules for this? I need to know because the text shown in the "peek" with a single image needs to relate specifically to that image.
The documentation isn't very explicit, but you could find this out pretty easily through experimentation. Alternatively, you could use the object model that provides friendly names in the NotificationsExtensions helper library in the tiles sample on MSDN (or look directly at the source mapping the friendly names to the identifiers in the helper library source: TileContent.cs).
For the specific template you mentioned, example XML is provided below with details about each image provided in the alt tag.
<tile>
<visual>
<binding template="TileWidePeekImageCollection06">
<image id="1" src="image1.png" alt="Main image on top"/>
<image id="2" src="image2.png" alt="Small image - row 1, column 1"/>
<image id="3" src="image3.png" alt="Small image - row 1, column 2"/>
<image id="4" src="image4.png" alt="Small image - row 2, column 1"/>
<image id="5" src="image5.png" alt="Small image - row 2, column 2"/>
<image id="6" src="image6.png" alt="Image with text"/>
<text id="1">Text Header Field 1</text>
</binding>
</visual>
</tile>

Informix IDS 12.25 is returning NULL whenever an #attribute is specified. In the image below we have the same document being queried by two statements. The difference between the statements is that one of them specifies an #attribute. While the other doesn't. And, as is possible to see in the image, the attribute indeed exists, because it's returned by one of the columns.
I've been searching a lot, seeing documentations and documentations, all places are saying that the syntax is correct. I don't know what to do anymore. Really thanks.
[Edit]
Here goes a sample of the xml File I'm working with:
<Frame>
<Shape sizeX="5400" sizeY="4400" distance="1800">
<ShapePoint>
<Point direction="0" radius="266" />
<Point direction="144" radius="280" />
<Point direction="243" radius="289" />
<Point direction="279" radius="291" />
</ShapePoint>
</Shape>
</Frame>
Alternative approaches for this problem, if mainly using the database engine, also would be extremely welcomed.
It's definitely a valid Xpath, except the first one selects a node, and the one that isn't working selects a string, which makes me think extractclob() is having a problem with this type of result.
Here's my test in Python to demonstrate this is the correct xpath for the given xml.
In [16]: tree.xpath('/Frame/Shape/ShapePoint/Point[1]')
Out[16]: [<Element Point at 0x102d68bc0>]
In [17]: tree.xpath('/Frame/Shape/ShapePoint/Point[1]/#radius')
Out[17]: ['266']
What happens if you use extractvalueclob() instead?

I couldn't find the answer to this anywhere so I had to resort to ask here...
Is it possible to use a List View but instead:
<ListView>
<Row>
<Text> Row 1 </Text>
</Row>
<Row>
<Text> Row 2 </Text>
</Row>
</ListView>
Basically lay it out statically instead of using a render row, Especially if each row is going to have a much different layout. Using a render row function kinda makes it a pain to not have all identical layouts
We need to apply watermarks, both image and text with an opacity applied.
It seems from the documentation that this is possible for images, but it doesn't seem to work.
imageQuery="filter=alpha(0.5)"
And there appears to be no option for text watermarks. Am I missing something as I would have thought this would be a common requirement for watermarking.
Here is an example of what we are trying to achieve:
http://i.imgur.com/FGxynsE.jpg
Text layers can have an 8-digit color specifier. Opacity is the last two digits. I.e, FFFFFF99 would be a partially tansparent white.
<watermarks>
<text name="test2" text="Hello #{name}!"
vertical="true" align="topright" color="FFFFFF99" />
</watermarks>
I want to know what is the suitable replacement for this line.
this.__LZtextclip.text
I am using this to get the string present in the text node. This works fine in Openlaszlo 3.3 but in 4.9 and 5.0 it's giving a problem
I tried updating it to
this.sprite.__LZtextclip.text
And i am getting an error:
79: Error: Access of possibly undefined property __LZtextclip through a reference with static type LzSprite, in line: Debug.write(this.sprite.__LZtextclip.text);
Any idea why this problem is happening?
If you are trying to access the text content of a text field, why don't you just access the attribute text?
<canvas>
<text name="sample" id="gRead" />
<handler name="oninit">
gRead.setAttribute('text',"HI");
Debug.info(gRead.text);
</handler>
</canvas>
In OpenLaszlo 3.3 there is method getText(), which gives you the same value. Accessing mx.textfield in your code does not work for the DHTML runtime.
Edit: Added information regarding the stripping of HTML tags
The Flash Textfield class flash.text.Textfield provides an API to enable HTML tag content in a Textfield instance. There are two different properties, one called text, the other one htmlText. If you want to directly access the Flash Textfield object of an lz.text instance, it's a property of the display object of the lz.text instance:
// Flash Textfield instance
gRead.getDisplayObject().textfield
// Pure text content
gRead.getDisplayObject().textfield.text
// Formatted text
gRead.getDisplayObject().textfield.htmlText
You should be aware of the fact that Flash automatically adds HTML format to any textstring you set as content. When you do
gRead.setAttribute('text',"HI");
the textfield.htmlText value is
<P ALIGN="LEFT"><FONT FACE="Verdana" SIZE="11" COLOR="#000000" LETTERSPACING="0" KERNING="1">HI</FONT></P>
For the DHTML runtime, the text content is added as the innerHTML of a <div> tag, and there is no standardized API to retrieve the pure text content of a DOM structure for a tag with content. You could write your own function to extract the text content, or use JavaScript functions from existing frameworks - like the jQuery text() function - to achieve the same result for the DHTML runtime.
I guess the reason is that Laszlo started using the Dojo based rich text editor for text input with HTML formatting since OpenLaszlo 4.0 or 4.1.
The best approach to have consistent behavior across runtimes when stripping tags is to do the conversion on the server-side. That's especially needed if you wan to have consistent whitespace treatment in multiline text, since there differences in how browsers treat whitespace. The question how to best strip tags from strings in JavaScript has been answered before on Stackoverflow, e.g. JavaScript: How to strip HTML tags from string?
Here is a cross-runtime example which works in DHTML with Firefox, Chrome, and it should work with IE9+:
<canvas>
<text name="sample" id="gRead" />
<handler name="oninit"><![CDATA[
gRead.setAttribute("text", 'Hello <b>World</b> OL');
Debug.info("gRead.text=" + gRead.text);
if ($dhtml) {
Debug.info(gRead.getDisplayObject().textContent);
} else {
Debug.info(gRead.getDisplayObject().textfield.text);
}
]]></handler>
</canvas>
I found what is the problem. The problem is that i have to declare a variable and have to refer the property from that.
<canvas>
<library>
<text name="sample" id="gRead">
<method name="getTextFrom">
Debug.write("this.text" , this.sprite);
var mx = this.sprite;
Debug.write("this.text" , mx.textfield.text);
</method>
</text>
</library>
<handler name="oninit">
gRead.setAttribute('text',"HI");
gRead.getTextFrom();
</handler>
</canvas>
Is it possible to query the Wikipedia API for articles that contain a specific template? The documentation does not describe any action that would filter search results to pages that contain a template. Specifically, I am after pages that contain Template:Persondata. After that, I am hoping to be able to retrieve just that specific template in order to populate genealogy data for the openancestry.org project.
The query below shows that the Albert Einstein page contains the Persondata Template, but it doesn't return the contents of the template, and I don't know how to get a list of page titles that contain the template.
http://en.wikipedia.org/w/api.php?action=query&prop=templates&titles=Albert%20Einstein&tlcontinue=736|10|ParmPart
Returns:
<api>
<query>
<pages>
<page pageid="736" ns="0" title="Albert Einstein">
<templates>
...
<tl ns="10" title="Template:Persondata"/>
...
</templates>
</page>
</pages>
</query>
<query-continue>
<templates tlcontinue="736|10|Reflist"/>
</query-continue>
</api>
I suspect that I can't get what I need from the API, but I'm hoping I'm wrong and that someone has already blazed a trail down this path.
You can use the embeddedin query to find all pages that include the template:
curl 'http://en.wikipedia.org/w/api.php?action=query&list=embeddedin&eititle=Template:Persondata&eilimit=5&format=xml'
Which gets you:
<?xml version="1.0"?>
<api>
<query>
<embeddedin>
<ei pageid="307" ns="0" title="Abraham Lincoln" />
<ei pageid="308" ns="0" title="Aristotle" />
<ei pageid="339" ns="0" title="Ayn Rand" />
<ei pageid="340" ns="0" title="Alain Connes" />
<ei pageid="344" ns="0" title="Allan Dwan" />
</embeddedin>
</query>
<query-continue>
<embeddedin eicontinue="10|Persondata|595" />
</query-continue>
</api>
See full docs at mediawiki.org.
Edit Use embeddedin query instead of backlinks (which doesn't cover template inclusions)
Using embeddedin does not allow you to search for a specific person, the search string becomes the Template:Persondata.
The best way I've found to get only people from Wikipedia is to use list=search and filter the search using AND"Born"AND"Occupation":
http://en.wikipedia.org/w/api.php?action=query&list=search&srsearch="Tom Cruise"AND"Born"AND"Occupation"&format=jsonfm&srprop=snippet&srlimit=50`
Remember that Wikipedia is using a search engine that doesn't yet allow us to search only the title, it will search the full text. You can take advantage of that to get more precise results.
The accepted answer explains how to list pages using a certain template, but if you need to search for pages using the template, you can with the hastemplate: search keyword: https://en.wikipedia.org/w/api.php?action=query&list=search&srsearch=hastemplate:NPOV%20physics
