.net - Don't Create Local Variable To Hold The Reference Of The Object?

Nov 17, 2010

How does the GC dispose objects created in the following 2 scenarios?

1)

Private Function DoSomething() As Boolean
Return New DatabaseManager().Insert()
End Function

2)

Private Function DoSomething() As Boolean
Dim mngr As New DatabaseManager()
Return mngr.Insert()
End Function

In Option 1, I don't create local variable to hold the reference of the object. In Option 2, I hold the reference in local variable.What option is better and why? (if any)

Gained By Using The Function Itself To Hold The Return Value Instead Of Declaring A Local Variable?

Oct 28, 2010

What's best practice (in VB.Net):

Function GetSomething() as String
GetSomething = "Here's your string"
End Function
or
Function GetSomething() as String
Dim returnString as String = "Here's your string"
Return returnString
End Function

Obviously, neither of these implementations make any sense, but they're just meant to illustrate my point. Is there anything to be gained by using GetSomething itself to store the return value instead of declaring returnString locally and then returning that (does it avoid having an extra string allocated/instantiated - and if so, are there any performance/memory benefits)?

So I do not know at design time if the var ms is going to be a stringreader or a memorystream. So I am trying to do basically this:

Dim ms as object = myfunction...
Dim mytype As Type = ms.GetType
Dim returnedobject = ser.Deserialize(CType(ms, mytype))

But I get an error saying "type mytype is not defined". How can I do this?

Structure Hold Small Number Of Reference Types?

Jun 10, 2009

Is it okay for a structure variable to hold a small number of reference types? I thinks it's fine because the pointers themselves are not that big, regardless of what they're pointing to. But I never did fully figure out the whole heap/stack thing, so I'd like to make sure.

C# - Inline Definition And Long-declaration Of A Variable

Feb 20, 2012

im sure im mis-wording the concept but here it is anyways. I know in CSharp you can do

el.AppendChild(new UISize(file, "TSize") { CX = 95, CY = 20 });

which declares a temporary bucket variable and then assigns the associate property values to the variable. Which then sends it to the XMLElement AppendChild method. What is this design concept called? What is the conversion to VB.Net? I have tried using my own online utility that does a 90-95% conversion rate from C# <-> VB.Net. It has failed in this instance, and so need a hand-up on what i am looking to do to convert this from C# to VB.Net. I would really like to not have to do a long-declaration of a variable with assignments, if at all possible.

Unsigned Long Random Number?

Jul 19, 2011

I'm trying to generate random dates in between two dates that are selected with a date and time selection control.Ideally, I would like to get the 'ticks' of each date, generate a random number between those, and then convert that back into a date.However I'm getting arithmetic overflow errors when I try to generate a random number from the between the ticks. I've tried many approaches - directly seeding with both the low and high date ticks, as well as subtracting.

Private Function randomDate() As ULong
Dim rand As New Random(Date.Now.Ticks Mod Integer.MaxValue)
Dim holder As ULong = DateTimePicker2.Value.Ticks - DateTimePicker1.Value.Ticks

User Enters A Password - Must Be At Least 3 Characters Long - At Least 1 Number And 1 Alphabet Character

Mar 28, 2012

My homework assignment is to create a project where a user enters a password that must be at least 3 characters long with at least 1 number and 1 alphabet character. After that the password has to be encrypted so that vowels become X, numbers Z, and it reverses. For example, a password of CS2301 would be ZZZZSC. There's supposed to be Loops to extract 1 number/letter at a time and search for them in the string to validate, and I don't know what to do. The form itself has a Text Box to enter a password and a label to display the new one, and a Go button.

This is what my code looks like so far.

Option Strict On
Option Explicit On

Public Class Form1

Private Declare Function BlockInput Lib "user32" (ByVal FBlock As Long) As Long?

Dec 26, 2009

In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.

BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor

Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:

FrmMain.BlockFrmMainInput()With these functions is the Main window:

[Code]...

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.

Console Random Number To Variable?

Nov 8, 2009

I am making a simple console game. If you have ever heard of the board game code breaker you will understand better.

In my version of the game you will have to figure out a four number combination. The only numbers it can be is 1, 2, 3, or 4.

I need to generate four random numbers and put each on into its own variable. This allows me to call back each number.

How do I do this? I have been doing some research on random numbers and I use this code to generate four random numbers

Dim rnd As New Random()
Console.WriteLine("20 random integers from -100 to 100:")
For ctr As Integer = 1 To 20
Console.Write("{0,6}", rnd.Next(-100, 101))
If ctr Mod 5 = 0 Then Console.WriteLine()
Next
Console.WriteLine()

But I can't figure out to put each number into a variable so I can call the same numbers back.
