I want to get an element's property (for instance, value) in WebKitGTK. I can easily get an attribute, and I can also get some properties of some types by using e.g. webkit_dom_html_input_element_get_value, but is there a general way of getting any property of any element which has that property?

I am using entget function in order to get all the properties of a certain object. So I have the table of dotted pairs that describe the properties of the object but now I want to use the VLAX-OBJECT functions, such as VLAX-COPY or VLAX-MOVE. So I need to convert it from the ads_name type to VLAX-OBJECT type but I can not handle to do it. Can you suggest any Idea to do it please?.
You can use the vlax-ename->vla-object function to get the VLAX object from the entity name
I'd like to copy all properties from a NSManagedObject over to a "regular" Swift class. I don't want to do this manually, i.e. make a regular class with all the properties for every NSManagedObject and then manually copy all those values.
I do know how to read property names and values dynamically from my managed object, but how to set them on a Swift class in a way that I can then use those values like
mySwiftObject.name
which returns a String or
mySwiftObject.age
which returns a Number (as those are the types on the Managed Object). Custom subscripting and stuff like that came to my mind, but I didn't manage to achieve this... Is there a nice way to do exactly that?
I have a generic List as shown in below.
List<UsrProfile> lst = GetUsers();
lst.Sort();
ddlUser1.DataSource = lst;
ddlUser1.DataBind();
Now the dropdown has both Value and Text. Now I do I sort by Text using the Generic list.
Please help.
I cannot use LinQ
If I understand the question correctly (and I may not...it's not very clear), you want to sort the list by a specific member of the UsrProfile class. Specifically, the Text property.
This is easy to do: lst.Sort((u1, u2) => u1.Text.CompareTo(u2.Text)); should do what you want.
This passes a Comparison<UsrProfile> delegate instance to the List<UsrProfile>.Sort() method, allowing it to customize the comparison logic used for the sort. In this case, rather than comparing whole UsrProfile objects against each other, it just compares the Text property between objects.
I am using Dozer mapping. i have two pojo1 and pojo2. pojo1 values to be mapped to pojo2. Pojo1 has 3 properties and Pojo2 has 4 properties. i am able to map 3 properties form pojo1 to pojo2 but to map fourth property i dont have property in pojo1. to map fourth property i cannot take value from pojo1, directly i need to give the value by taking from Enum. Please help me is it possible to give value to any property through mapping file?
value from enum directly not from pojo1
fourth property
Thanks!
As far as I know this is not possible in a convenient way. The only way to do this atm is by either having a custom converter, or by modifying one of the POJOs.
With a custom converter you could just map pojo1.field3 to pojo2.field4. The converter completely ignores pojo1.field3, and just sets the pojo2.field4 to your enum value.
Another solution is to just modify pojo1 and add a field4 which always returns the enum value.
And the third solution is to modify pojo2, and just set field4 in the default constructor. If you can't modify the default constructor, you can use a custom create method or a custom bean factory to achieve the same.
I've been doing dozer mappings a lot, and would like some more convenient solution for this too. Unfortunately I don't think there is any atm.
Let me know how it works out for you!
In core data, in the xcdatamodel file, if i want to specify a parent object, but for one of the children of the parent object, i want a property to be optional, and for the other, i don't want to check optional, is there a way to do that? or should i just take the property out of the parent and put it in the children so that I can make one optional and the other not optional?
I think the best way to do is to make the property optional, and changing this behavior in some of the subclasses by implementing your own validation mechanism (documentation available in the Core Data docs, validation is part of the API)
Then by default the property is optional, but in the subclasses you want it to be required you can simply invalidate the property's value when it's nil or empty, and even make it depend on other factors.
