In a UWP, I use the "CollectionViewSource" in a xaml file, and when I want to bind the source for it, it doesn't work and the error information is
Input string was not in correct format
What can I do for solving this problem ?
You have to parse the json file into a collection from the corresponding type, then bind to that collection.
Hope it helps you out.

I want to define a number of xml formatted strings in resource file and use the strings in qml code. Is it possible? How to do it? I would be really appreciated any example.
As I know there is no way to store strings in resource file. But you still do that in another way.
First way: create language file with qt translation tool. As bonus you can store string in several languages.
Using in QML is very easy:
Text {
text: qsTr("myTextId");
}
See that link for more info.
Second way: store each string in different resource file.
But in this case you need to extend QML with C++ plugin to get ability to read files.

I'm new at Visual Basics and I'm trying to fill the forms of the following website:
http://www3.dataprev.gov.br/cws/contexto/hiscre/
I tried using this line of code:
WebBrowser1.Document.GetElementById("nome").SetAttribute("Value", "Test")
However, whenever I try I got the following error:
A first chance exception of type 'System.NullReferenceException'
occurred.
I would appreciate if someone could help me to accomplish this, it would save me a lot of time if I could automate this task.
Thank you in advance, Daniel.
WebBrowser1.Document.GetElementById("nome").InnerText = Test
That will select the input named "nome" and fill it with the text "Test"
Hope this helps.
According to Microsoft documentation, the SetAttribute function your are using is case sensitive.
You'll need to replace "Value" for "value".
WebBrowser1.Document.GetElementById("nome").SetAttribute("value", "Test")
However, the kind of error message you are getting seems to occur before the call to the SetAttribute function. Go in debug mode and make sure that every objects used before the SetAttribute function are not null.

Please help me with any related link or any code.

In WPF, there's something called TemplateSelector, which does what you're asking for. In Silverlight, you have to write it yourself. This should help you.
