Difference Between Return And Assignment?

Sep 28, 2011

What is the difference between this two ways of returning value in a function in VB.NET?

Using Return Statement:

Public Function Foo() As String
Return "Hello World"
End Function

Using Assignment:

Public Function Foo() As String
Foo = "Hello World"
End Function

I'm using the first one then I saw someone using the second. I wonder if there's a benefit I could get using the second.

FormClosing And Application.Exit Is Causing The MessageBox To Ask If Want To Exit Twice

Jun 12, 2007

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.

Several IF Statements With Exit Sub Or Nested IF Statement Without Exit Sub?

Dec 9, 2011

Now I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

Return An Object As The Return Value Through A RealProxy Transparent Proxy?

Oct 7, 2010

I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.

I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string

.net - 'Exit Sub' On DialogResult.OK Button?

Jan 4, 2011

I have a VB.NET form (CopyScenarioForm) with a OK button (DialogResult property = OK) and also assigned it as 'Accept Button" for the Form.

I show this form from my main Form (mainForm) using

If DialogResult.OK = CopyScenarioForm.ShowDialog() Then
DoSomething()
End if

Now when user clicks on the CopyScenarioForm.OK button, I want to validate his entries and if invalid I want to 'Exit Sub' from the OK button's click handler but when I do that the form still closes out and DoSomething() gets executed. Is there a way to stop this and keep the form alive and only exit if the inputs are valid. I noticed, if I change the OK button's DialogResult property to 'NONE' instead of 'OK' then it doesn't cause it to close. but then how Do I know how the user exited the form to execute DoSomething().
