I have a content type called "FormContentType". This type has a field called "FormAlias". I have number of Macros pointing to UserControl forms. In corresponding templates of contents of "FormContentType" type, I'd like call that Macro based on the value entered in "FormName" field. I want to have some thing like this:
<umbraco:macro alias="[#FormAlias]" runat="server"/>
Notice that macro alias is dynamic and is based on what is entered in "FormAlias" field of content. But it does not work. If I put the name of one of those form macros explicitly, it works. But using above statement, it does not work. Is this something related to page life cycle?
Could you please help me?
You will need to create a wrapper macro which loads in the macro dynamically.
See this blog post for details:

I'm thinking of creating a VSCode extension to help people use a library I am creating. I've looked in 50 places and can only see documentation on getting the plain text of the document in which the completion suggestions are triggered.
My library exposes a function with two parameters, both objects with the same keys, but the first one will be defined already and the 2nd one will be passed in as an object literal. For example
const obj1 = {a:1, b:2};
doLibraryThing(obj1, {a:[], b:[]});
I want to provide code completion, or a snippet, or anything that can detect that doLibraryThing is being called, and know what properties were defined in obj1, even though usually it will be imported from another file; and then use those properties to generate the suggestion with the same properties, {a:[], b:[]}.
Is this possible?
I want to create a .png file of a HTML page in angularjs and download it. For this I'm currently using dom-to-image.js and using the domToImage.toBlob function and passing the node element to it. But internally when it goes to dom-to-image.js it throws the error:
node.cloneNode() is not a function
Can anyone please assist me here?
Thanks
This error arises when you attempt to call cloneNode() on anything other than a single DOM node.
In this case, the error is coming from the dom-to-image library, which calls that method internally.
Note that without a code snippet, its hard to identify the precise issue with your code, but the point is, when you call domtoimage.toBlob(), you need to supply a single DOM node.
So double check what you are calling it with. If you are selecting by class, for instance, you could end up with more than one element.
Its best practice to be precise with which node you want to convert to a blob - use the id attribute, like this:
domtoimage.toBlob(document.getElementById('element')).then(...)
where element is the id of your target node.
Its also possible you're selecting with angular.element() or even using jQuery directly.
In both cases, this returns an Object -- which you can't call cloneNode() on.
Also note the following from the Angular docs for angular.element():
Note: All element references in AngularJS are always wrapped with jQuery or jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
Which means you would observe the same behavior in both cases, e.g. both of these:
domtoimage.toBlob($('#element')).then(...)
domtoimage.toBlob(angular.element('#element')).then(...)
would result in the error you see. You can index the Object before supplying it to domtoimage.toBlob(), perhaps like this:
domtoimage.toBlob($('#element')[0]).then(...)
domtoimage.toBlob(angular.element('#element')[0]).then(...)
and that would also work.

I'd like to create a code template in eclipse and specify where the user can type in the variable name if there are multiple instances of the same variable, because the code completion is not available at the first instance.
This example is written in Progress ABL, as the variable name is defined before the variable type in this case, but it's not really language related if something like that is possible within the scope of templates in eclipse.
Example:
define buffer bTablename for Tablename.
Template:
define buffer b${tablename} for ${tablename}.
But I want to start writing at the second ${tablename}, is there a way to change the "tab order" or something to accomplish that?
The JFace template language doesn't allow to specify a tab order for the template variables.
You would need to either write your own extension for the template completion or contribute changes to Eclipse that introduce that functionality.
I'm doing some competitions on a website called topcoder.com where the objective is to solve algorithmic problems. I'm using Eclipse for this purpose, and I code in Java, it would be help me to have some predefined templates or macros that I can use for common coding tasks. For example I would like to write methods to be able to find the max value in and int[] array, or the longest sequence in an int[] array, and so on (there should be quite many of these). Note I can't write these methods as libraries because as part of the competition I need to submit everything in one file.
Therefore ideally, I would like to have some shortcut available to generate code both as a method and as a calling statement at once. Any ideas if this is possible?
Sure you can - I think that's a nifty way to auto-insert boilerplate or helper code. To the point of commenters, you probably want to group the code as a helper class, but the general idea sounds good to me:
You can see it listed in your available templates:
Then as you code your solution, you can Control+Space, type the first few characters of the name you gave your template, and you can preview it:
And then you can insert it. Be sure if you use a class structure to position it as an inner class:
Lastly - if you want to have a template inserts a call to method from a template, I think you would just use two templates. One like shown above (to print the helper code) and another that might look like this, which calls a util method and drops the cursor after it (or between the parentheses if you'd like, etc):
MyUtils.myUtilMethod1();${cursor}
I have a custom node type for which I want to have a field that uses a special combobox based on list_text. When one chooses the type list_text it is normally possible to enter a static list of selectable texts, however, I want this list to be dynamic, i.e. based on the results of a db_query. What is the best way to do this using Drupal 7?
A simple example for clarification: A node of this custom type X contains a field that points to another node, so whenever a node of type X is created I want a combobox that contains all other nodes.
(Best solution would be to only display the combobox during node creation, and no longer during edit. But I could also live with it if the combobox was shown during the edit as well.)
I have tried to customize options_select by defining my own data type and implementing hook_options_list accordingly. The combobox was displayed during creation with the correct values, however, I could not save it.. I have no idea what went wrong there, but on the first submit it would change to a different theme, and when I tried again I got an internal server error. Am I on the right track at all with defining a completely new data type for the field? there surely must be a simpler way?
You're right in that you don't need a new datatype. Here's a good tutorial on how to do this. It's not specifically for D7 but I didn't see much that wasn't still applicable. There may be a better way to do it in D7 specifically but I would love to know it too if so :)
The tutorial linked by allegroconmolto sent me on the right way. Thanks for that.
Here's the simpler way of doing it: tutorial
Basically, it is, as I assumed, a common problem and hence a simple solution for it was included in the webform module by now. It provides a hook_webform_select_options_info which can be used to register a callback method. The callback method is then called each time a corresponding option select of a webform is shown, so that you can easily fill it with the results of a dbquery or anything else. Works like a charm and takes next to no time to implement.
