The difference is that they DO DIFFERENT THINGS! ‘Return value’ does 2 things: 1. It sets the function return value at that point 2. It immediately exits the function No further code in the function executes! ‘Functionname = value’ does 1 thing: 1. It sets the function return value at that point Other code in … Read more
Set the highlighted properties. Set MaximimSize and MinimizeSize properties the same size
Dim val = DirectCast([Enum].Parse(GetType(Gender), “Male”), Gender)
No, there is no equivalent of the out keyword in VB. However, VB does automatically initialise all local variables in a method, so you can use ByRef without needing to explicitly initialise the variable first. Example: Sub Main() Dim y As Integer Test(y) End Sub Sub Test(ByRef x As Integer) x = 42 End Sub … Read more
The difference between VBA and VB.NET is just because VB.NET compiles continuously in the background. You’ll get an error when you compile the VBA. Like Jonathan says, when programming you can think of VB.NET as case-insensitive apart from string-comparisons, XML, and a few other situations… I think you’re interested in what’s under the hood. Well, … Read more
The PlayStateChanged event is quite notorious. It was really meant to just update a UI element that shows the state. Doing anything with the player in that event is very troublesome. A call to MessagBox can have an affect because it pumps a message loop, always a big deal for ActiveX controls. The best way … Read more
A module is really very similar to just a class containing only shared members. In fact, in C#, there is no such construct as a “module”. You cannot write any application without having at least one module or class, so I suspect your real question is not “why use classes and modules”, but rather “why … Read more
Since you declared TypeTest as a Class, that makes it a reference type (as opposed to Structure which is used to declare value types). Reference-type variables act as pointers to objects whereas value-type variables store the object data directly. You are correct in your understanding that ByRef allows you to change the value of the … Read more
You should have to use Date.ParseExact or Date.TryParseExact with correct format string. Dim edate = “10/12/2009” Dim expenddt As Date = Date.ParseExact(edate, “dd/MM/yyyy”, System.Globalization.DateTimeFormatInfo.InvariantInfo) OR Dim format() = {“dd/MM/yyyy”, “d/M/yyyy”, “dd-MM-yyyy”} Dim expenddt As Date = Date.ParseExact(edate, format, System.Globalization.DateTimeFormatInfo.InvariantInfo, Globalization.DateTimeStyles.None) OR Dim format() = {“dd/MM/yyyy”, “d/M/yyyy”, “dd-MM-yyyy”} Dim expenddt As Date Date.TryParseExact(edate, format, System.Globalization.DateTimeFormatInfo.InvariantInfo, Globalization.DateTimeStyles.None, … Read more
It is the same as static in C# and most other languages. It means that every object in the class uses the same copy of the variable, property or method. When used with a method as it is static you don’t need an object instance. MyClass.DoSomething() rather than Dim oObject as New MyClass() oObject.DoSomething()
