VS 2008 Difference Between Nesting 'If' In 'Else' & Using 'ElseIf'?
Jul 15, 2011
What is the difference between nesting an 'If' statement in and 'Else' statement and using an 'ElseIf' statement? In the example below, the controls labeled [nAMEoFdAY]Limit are instances of the NumericUpDown object, each representing a day of the week. I need the application to decide which NumericUpDown to draw the value from based on the current day of the week. Will this code work or should I use the 'ElseIf' statement, and if so, how?

Is there a way to nest a datatable into another datatable? I know you can do this with gridviews but thats not what I'm looking for.
Also, I don't want to merge the datatables. What I'm trying to do is have a datatable with 2 columns and each column containing different datatables.

Does VB.NET have any scope nesting operators like {} in C type languages? Example C++ type code:
int i;
i = 0;
{
int i;
i++;
}

I seem to be having a lot of trouble with this project. I am trying to update this atabaseI know that the routines are working (atleast the delete and update of records),but it seems to be going straight from the If statement right to the End If and not attempting the ElseIf statements. If it is something simple...sorry for the dumb question, I'm very new to rogramming in general.
Public Sub Delete()
Dim lngRecordNumber As Long
Dim StartTime As String

I have the following portion of a VB Script, and for whatever reason, no matter the input data the first If statement is successful, which is cauing incorrect data in my output file.
Script excerpt (this is a function):
On Error Resume Next
code goes here
If Err.Number = 0 Then
WScript.Echo "It worked!"

Assume I have an If-ElseIf decision to make. Do all ElseIf's get executed after one has been found true? [Code] Obviously that is not a real subroutine but I wrote that just to clarify what I'm asking. When this is run, on the second ElseIf the value is equal to 5 so whatever is inside that ElseIf would execute. Once that happens do the following ElseIf's get checked or does the program immediately go to the End If?

Since plan1 and plan 2 all plans having same fields but due to their variable values total I make 4 tables having one to many relationship so that duplicate data for few fields get accomodated under different Id. and now there is no need of filtering data also and 4 databinding sources give a serial values to my comboboxes to select veriables to get further calculations.
I have another question now in further calculation there are many calculation sets with using if elseif if statment for such number of sets how to connect them since in form1.vb code file
if I place them one after other some calculations get correct some gets wrong.I hope you understand my question.is there any method to connect such sets( if elseif if) statments one by one under one buttion_click to get correct answer for all the sets.

I've made some function that generates an email template. Code it generates is pure HTML with CSS. Problem is compiler does this odd error and highlights each time '#' sign appears which is needed to define colors in CSS. I did try to change '#' to '/pound/' and then string.Replace() on RETURN but no luck. I'm more into C# so there i can escape special characters by using '' before them but something f$#$ed up there... Once i remove '#' all back to normal and compiles well.

ok after some testing, i've concluded that select case is never faster than if/elseif unless there are above 10 elseifs (or cases)is it accurate? (or rather, what shld it be)

Is there an easier way to do this?
The .ColorReportedDate, .ColorTypeKey, .IsColorKeyNull, etc are from my strongly typed dataset row.
If .IsColorKeyNull Then
.ColorReportedDate = Now()
ElseIf cboColorType.SelectedValue <> .ColorTypeKey Then
.ColorReportedDate = Now()
End If

i was trying to make a free microsoft word plugin in vb.net. It automatically fills a web form. The main problem with the plugin is that it uses web browser control and once it has filled a form it will need to navigate another form. The form can only be filled once it has completely been loaded.so my approach is
1. navigate to first site when form loads
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://google.com")
End Sub
2. use an integer i and use if statements to check which form to fill :
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEv entArgs) Handles WebBrowser1.DocumentCompleted
If (i = 1) Then[code].....
3. this is the main step. you see when main form loads, i=1 so browser goes to google.com (first form), when form is completely loaded, itchecks for value of i. Since i=1, it fills google. After filling and continuing i=2 and browser goes to my personal account page. This means browser again loads the document. Now i=2, so it fills my personal detalis. Now the timer starts. Since i=3, browser navigates to second site and fills the details.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If (i = 3) Then
WebBrowser1.Navigate("http://blogger.com")[code]...
now the problem arises. The browser does not go to the third site. Once the timer has been stopped and started, the following code does not goto the elseif part (i.e. i=5) why is that so?

I'm wondering if this is a good way of doing data access, in terms of all the database objects being properly closed and disposed? For example:
Using conn As New SqlConnection(MyConnectionString)
Using cmd As New SqlCommand("some SQL here", conn)
... add parameters ...
conn.Open()
[code]....
Is nesting Using like acceptable practice? If I exit the method at some point within the Read() loop, will the use of Using like this ensure all objects are cleaned up properly regardless?

I've been using VB for some time now, but I must admit I am a little confused. I started learning with 2002, then 2003, 2005 and now 2008. I think database coding must have been going through a kind of transition when I was trying to teach myself the basics. As a result, I am not entirely clear on a few things..
1) What's the difference between a DataTable and a DataSet. Why would I use one over the other?
2) Personally I dislike using DataAdapters etc and much prefer typing my connections in code so I can see what's what. When using the visual tools things are 'hidden' from view and it's not clear what's going on - do others find the same or is this just me being old fashioned?
3) Using my code-based approach (ie: creating SQL connection, using ExecuteNonQuery and a SQLDataReader to read the results into my application) - is this less efficient than the alternative methods?
4) Finally...LINQ. Is it any better and should I be using it as standard practice?

I am used to working with menubars in v2003 and before and could merge menu items with no problem. I used the code below in combination with merge order settings in the menu bar and it worked great. Now using Menustrips, I find my code does not want to convert since there are Items in the menustrip and menuitems in the menu bars.
'Determine if a Menu exists.
Public Function DoMenuExist(ByVal mnuItem As String) As Boolean
Dim itm As MainMenu
[code]....
I need to merge a child menustrip into the parent menustrip when the user opens a module from clicking an item in the parent menustrip item.

from_time falls >= 22:00 of the From_date & the to_time falls <= 06 of the To_Date
