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!"

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 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.

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?
View 5 RepliesSince 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.
View 2 Repliesok 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)
View 9 Repliesi 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?

The problem, The INSERT statement works fine in the form load but not in the button click event?
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?

View 3 RepliesI'm writing something that will examine a function and rewrite that function in another language so basically if inside my function F1, i have this line of code var x=a.b(1) how do i break up the function body into symbols or "tokens"?I've searched around and thought that stuff in System.Reflection.MethodInfo.GetMethodBody would do the trick however that class doesn't seem to be able to have the capabilities to do what i want..dit 2:basically what I'm trying to do is to write a program in c#/vb and when i hit F5 a serializer function will (use reflection and) take the entire program (all the classes in that program) and serialize it into a single javascript file. of course javascript doesn't have the .net library so basically the C#/VB program will limit its use of classes to the .js library (which is a library written in c#/vb emulating the framework of javascript objects)
View 4 Replieshow to use them then before, but am still a little confused with a few aspects. Here goes:
1.) Lets say you have a method that checks for a certain condition(s) and if it fails Throws an exception. Does it have to be in a try/catch block? Meaning can the "Throw" statement exist in a block with no try/catch statement?
2.) Now lets say we have a method that has a try catch block and in it there is a throw statement. When the throw statement is executed does it first try to find an appropriate catch block in the same method or does it immediately go back to the calling method without looking at the catch statements in the current method where the exception was thrown?
3.) I created a custom exception class that inherits from ApplicationException. Next I created a method which has a catch block that catches this type of exception and does some action. Is the System(i.e CLR) smart enough to throw an exception of this type, or does it only throw exceptions from SystemException?
4.) I know that some people are more liberal in their use of exceptions and others use it more sparingly when truly strange stuff happen like the DB going down. I am writing code where I am getting some info back from the database, converting it and then storing it. Sometimes there might be data that comes back from the database and other times the field is empty and the Null value comes back. Therefore in the instances where Null comes back from the database I should not convert the value to anything, since I will get an error. What should I do in this situation? Should I let the CLR throw the exception when it goes to convert the Null value or should I check for the Null value and if it exists not convert?
5.) In general when I throw exceptions, is it sensible to only throw exceptions of the type Application Exception or are there instances where the programmer throws exceptions of the type SystemException?
I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?

If itm.Text Like TextBox1.Text & "*" Or itm.SubItems.Item(1).Text Like TextBox1.Text & "*" Then

However the "if" statement shows an error " statement cannot appear outside of a method body" and the Microsoft solution is to "move statement into a procedure or subroutine"
I have coded a case statement that changes the background colour of a panel. [code]When the code is run, it works for the case of colour1 that is NOT 1 or 2. However, when the colour1 is 1 or 2, it is supposed to pick a number from set array and run another case statement. Instead, it only picks the last value (for 1, this is 5, and for 2, this is 7).

Using writer As XmlWriter = XmlTextWriter.Create(file)
[code]....
I've read that you're only supposed to use a Using block on objects that have a .Dispose() (i.e. implements IDisposable), which is why I'm thinking there shouldn't be a Using on "writer", but instead a writer.Close() at the end. But "file" has both a .Dispose() and a .Close(), so which do I use? The Using or a file.Close()?
Note: I'm using an XmlWriter because I can customize the output. I removed the settings here, though.
