Skipping Over ElseIf Statement?
Mar 19, 2010
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

A co-worker wants to convert the following IfThenElseIf statement into a Select Case statement.
Explain why this is not possible.
If temperature = 100 Then
X = 0
ElseIf population > 1000 Then
X = 1
ElseIf rate < .1 Then
X = -1
End If

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!"

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

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.

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?

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)

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?

This is my frist post on the forum So I hope I am giving enough info, If not let me know if there isanything I missed.I have currently completed a project where I do a Query in SQL Server 2000 in VB 2010 and produce reports for each Tax id. When I Debug the program it finds the number and processes the reports, when I just let it run as an executable it does not pick up or find the number.
This number happens to be the last number coming back from the query and it processess in a loop while Not filename.EOF it goes thru 4 seperate routines and then loops back to get the next taxid. I did not put any routines to sleep and I am thinking maybe the application is just stepping on itself, could this be right? Thecreatereport path does a sql execute for the appropriated Table against the TaxID an the current Cycledate, then produces the report va CR2010(beta) and exports it as a pdf file to a directory on the shared sever.

With the code above, I'm trying to create and insert records into a MySQL database. The issue here is that not all records are inserted. If the XML document I'm reading from has 80 records, only 40, or 66, or some other number get put into the database. I'm guessing this is because the code is trying to insert the records faster than the database can handle them? What would the correct way to make sure the record is in the database before moving on to the next one?

My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ListBox1.Items.Count <> 0 Then : ListBox1.Items.Clear() : End If

The load event goes through two different List(of T) in its own For Each loop. When the form is run for the first time, the first list is populated, the second one is not so the first loop runs but the second one does not. Then an integer that would normally be modified by the second loop remains at 2 and is assigned to a private variable integer, _handsRemaining.
Here is what it DOES. It runs through the first For Each loop and populates the appropriate field. It ignores the second loop because there are no weapon Class instances in that list. Then it goes wrong. It IGNORES the remaining lines (including the third MessageBox.Show) and somehow assigns a value of 0 to the private variable, _handsRemaining.
Private _handsRemaining As Integer
Private Sub Inventory_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim hand As Integer = 2

I have two datatable that I pull information from a db. I have a complicated form, and I have found it easier to write a simple SQL statement to pull the records. I have then used other controls on the form to trim the info down even further. When a particular falls out of the secondary control it is then deleted from the datatable.
I am then going back through the datatable and performing other actions on the datatable. When I narrow the information, sometimes I'm getting a DeletedRow is inaccessible. I have been looking at a way to do an IF statement to see if a row has been deleted, but I haven't figured out a way to skip a deleted row. Is there a way to skip a deleted row that I'm not seeing.

I'm hoping somebody can help me with this... I am reading an XML file created from the server and all is good except that when I try to process the file it's always skipping one of the first child elements. And when I run a test with no processing, just a straight reader and looping through the elements, the 1st element is there. But as soon as I add a check to see if the node is an Element, it skips an "Attachment" element.Here's my XML:

I have a text file 'source'. I want to skip 4 lines then grab the 17th through 33rd characters and assign them to a variable. Then drop down to the 9th line and grab the 10th through the 19th character and assign them to a variable. Then skip to the 27th line and write each line to another file with these two variables appended to the end of each line. I can write the lines to another file easy enough but I'm not sure about skipping around from line to line or grabbing the variables.

I'm not really sure how to word it, if it is possible, but part of my program reads from a text file. It then pulls out the necessary information needed from that file by finding key identifiers. Right now the code is written to find the first key identifier and then read each line after that, locating each subsequent identifier and pulling the data from it. In a few cases, the format examples I've worked with are a bit different which results in a runtime error. How can I tell the program to essentially skip that part of the text file if it's not reading it right and continue moving on? Here is somewhat of an example of the text file.
DID/"DATA EXTRACTED HERE"
NAM/"DATA EXTRACTED HERE"
STR/"DATA EXTRACTED HERE"

is it possible to skip forward or backup to the previous record in a database within a Do Loop of an ExecuteReader routine? For example, with the following code:
DMDatabase01.Open()
DMCommand01 = New OleDbCommand("Select * From DB01Table01 Order By DB01F01, DB01F02", DMDatabase01)
DMReader01 = DMCommand01.ExecuteReader()
Do While DMReader01.Read = True

I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this
If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?
