Simplify My IF Statement?
Mar 10, 2010
So I have here a sub, that is called to check values in my program. It works as it is, but it is a very long line of code. I know there must be a way to simplify this. As long as it uses fewer than 10 lines (even though this is 3 lines, split up. Same thing in reference).
If (btnArry(1) = btnArry(2) And btnArry(2) = btnArry(3) And Not btnArry(1) = Nothing) Or _
(btnArry(4) = btnArry(5) And btnArry(5) = btnArry(6) And Not btnArry(4) = Nothing) Or _
(btnArry(7) = btnArry(8) And btnArry(8) = btnArry(9) And Not btnArry(7) = Nothing) Or _[code]....

I was just wondering how you would go about simplify this code as its getting very annoying manually going through and changing the index value for the arrays.

Is there a way to simply the Handles statement? What if i want this sub to handle 20 textboxes do I have to list each textbox there? I already have a loop in my script so i can cycle through my textboxes ("TextBox" & i.text). is there anyway to use a variable or a function after handles to get all the names of the text boxes?
Private Sub textChange(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress,TextBox2.KeyPress, TextBox3.KeyPress, TextBox4.KeyPress, TextBox5.KeyPress

I'm just wondering about this one. I'm creating an ASP.NET webform containing lots of textboxes etc. And I want to send an e-mail based on this stuff. And the e-mails body needs to go into a string. And the string is supposed to contain HTML code, but the syntax changes because of the string. So how can I simplify this? Is there any software or something that lets me do this? Perhaps paste in some HTML code and then convert this to string format, ready to use with vb.net?

I am writing a program to help simplify a weekly list of events for a web site without having to manually edit HTML code every single week.
The program takes event information from the user, stores it in a list box, and generates HTML code based on the user entry. The program basically enters in the user's inputted fields into a pre-set HTML template.
Here's how it's done:
1) I have a number of text boxes that the user fills out: "Date" "Event Title" "Age" "Location" "Details" etc.
2) The user clicks on the "ADD" button to store this event. The "Event Title" is shown in the list box, but I'd like for all of the information that was taken from the user before they clicked on "ADD" to be recalled in another text box.
3) The user can move events up or down in the list box, or remove them completely.
4) When the events have been sorted, the user hits the "GENERATE CODE" button and the html code is generated.
So lets say the list looks like:
- DJ Jim at Katrina Lounge
- DJ Heather at Zanzibar
- DJ Manny at Skybar
When the user clicks on the "DJ Jim" event, the full details that they entered earlier will be shown in a text box to the right of the list box. When they click on the "DJ Heather" event, the text box will reflect the details they entered for the "DJ Heather" event, and so on.
When the user click on "Generate", the program must be able to go through each item in the list box, recall the event details for that item, and plug in the variables for that item into the HTML code template.
The main question is, how can I store the information for each event (Event Title, Date, Location, etct.) while displaying only the Event Title for that even in the list box? If I know how to code this, it will be simple to display this information in the text box and recall the variables to plug into the HTML code
So the structure would be:

I have created a simply Pizza program (for a summer project not education related) that uses check boxes to determine what the customer wants. Basically a simple pizza ordering program.I was wondering as I have used the If statement over and other again for different parameters and variables, is it possible to use multiply arrays to simply the VB Code...I was advised to use Constructors in VB.Net Or is there a more simpler way to go about creating this program...or a better way of programing?What about decreasing the repetition in the code?

I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy.So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API?

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?

I'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)

how 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?

I'm not sure what I'm doing wrong, I am learning slowly but surely, and it is by no small margin because of the ave found here =) The error is occuring in the intResult = intSelection x intCount line of the SECOND Do While Loop.
The blue squiggle line is under "intCount" just FYI

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).

Dim x As New Serialization.XmlSerializer( ... )
Using file As New FileStream(myFile, FileMode.Create)
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.
