I'm currently searching for a way to pass in a parameter in a onMouseClicked function such as onMouseClicked="#GetBoxNum" in my .fxml document.
Sorry if this question has been asked already I couldn't find it when i was searching for it.
The only parameter that can be passed is the MouseEvent. So the answer to your question is: It is not possible to pass an arbitary argument.
Basically you can use a Listener for any specific component you have, and implement it in the controller initializer , and by using lambda expressions(within the listener) you will be able to call whatever function you want with whatever parameters you want.

I am having a tough time trying to pass a parameter into my method when I go to invoke it.
I new up a variable called setupNewCase, then I populate it with data. Once I do that, I then try to invoke the method. It normally works when I don't have a value to pass into it, but it doesn't work here in this case as I am trying to pass something into it.
To pass parameters to the invoked method you use the Parameters property on the InvokeMethod activity. Its available on the activity's properties grid and not directly on the designer.
You would use TargetObject when invoking a method on an instance object but since your CommonMethods class is static you won't ever instantiate it and therefore TargetObject should be empty.
I have a form which is used for automatic journal postings.
On that form I have a Ok command button and in closeOk method of the form I call the method from my datasource table.
In the JournalCheckPost class's infoResult() method I want to determine if the method is called from my form. I know that it can be done with caller methods but I don't know how exactly it should be done technically.
It is bad practice to make a method depend on where it is called from.
What you can do is to pass an extra parameter to the LedgerJournalCheckPost and infoResult can then check that. This can be done by introducing a boolean flag and a parm method.
I think, there can be many situations:
You want to pass some parameters from form
You want to manipulate the form (for example refresh datasource after action is complete)
Something other
But in all the cases depending on particular form is not a very good idea.
In first case you can set parameters from code using parm methods, or, better pass parameters using the Args class
In the second you can cast Args.caller to some interface that contain all the methods you want and manipulate the form using that methods (see \Classes\SysFormRun_doRe usages for example)
I haven't found anything about this.
In PL/SQL, if I provide a constructor for an object, the default one will still be created, or it's like in C++ or Java?
Yes, the default constructor is still there. Incidently, if you create another constructor with the same name and arguments you'll get an error PLS-307: too many declarations of ... when you try to use it.
This is a simple questions. I have researched this questions in my notebooks and books and the internet but cant find an answer
Why would we override the default constructor by adding parameters to it?
You would create a constructor for a class to manipulate its member variables according to whatever other conditions as soon as it's created. I get the impression you don't actually know what a constructor is.
Many languages (like C++/C#/Java) automatically create default no-arguments constructor when none defined in the class explicitly.
When you create a constructor in a class with or without arguments usually compiler stop creating default auto-generated constructor (depending on language specification). This is done on assumption if you have some non default initialization than automatically generated one is likely to not create object in a state you would expect.
Since having constructor with arguments is natural way to create objects it is essentially lead to "removing" default auto-generated constructor which probably can be called "overriding default constructor".
I'm invoking the ObjectDataSource InsertMethod programmatically. I've tried so save a couple of text boxes' value to the DB using the InsertParameters.Add() method, and it worked perfectly.
SqlDataSource1.InsertParameters.Add("CoName", CompanyNameBox.Text);
SqlDataSource1.InsertParameters.Add("Phone", PhoneBox.Text);
SqlDataSource1.Insert();
Now, given that I have an important number of variables, I've regrouped those variables in one object.
Now, it looks like there's no overload method that allow me to add a parameter accepting an object to the collection.
What the best way to do that? Any other alternative?
Thanks for helping.
All your paramaters will have to be provided one by one in your code, that is to say one call to add a parameter per property of your custom object.
