I'm trying to make this cleaner... I know there's lots of shortcuts for If statements, but I don't know what's best.
If item.RecurrenceId > 0 Then
xmlTextWriter.WriteElementString("recordtype", "2")
ElseIf IsNothing(item.OngoingEndDate) = False Then
xmlTextWriter.WriteElementString("recordtype", "1")
Else
xmlTextWriter.WriteElementString("recordtype", "0")
End If
I am a C# programmer but dabbling in VB.Net because everybody else in my team uses it. In the interests of professional development I would like to shrink the following If... Else... statement.
If cmd.Parameters("@whenUpdated").Equals(DBNull.Value) Then
item.WhenUpdated = Nothing
Else
item.WhenUpdated = cmd.Parameters("@whenUpdated").Value
End If
This is the code that i would like shortenning, it uses a progress bar and a label that counts down with it: I'm using the language of VB..[code]

Question: How to shorten this array creation ? I need to create an array of type ReportingService2005_WebService.Property with one property.
Something like:
Dim PropertyArray() as new ReportingService2005_WebService.Property(1)
I have to do this:
Dim PropertyArray As ReportingService2005_WebService.Property() = New ReportingService2005_WebService.Property(0) {}
PropertyArray(0) = New ReportingService2005_WebService.Property

Dim num as integer = 1.60285253
Msgbox(shorted num??)
I want msgbox to show only shorted version of that number, so It should give 1.06
And is is possible to make it round third number to higer? If I want limit it to 2 numbers only, it should show 1.06 as 1.1, but if number was 1.04 it shows shortened number as 1.0.
I have a function which generates a very large Integer (I do this by using Biginteger from vjslib.dll and I am able to operate all kind of arithmetic operators on such a biginteger.) But, My goal is to shorten this big integer into a small integer. Is there any algorithm? or a mathematical Formula which I can use to represent it in a small integer and use some reverse formula to get the original Big integer?
The big integer my function creates goes like this:
98761210112313489375987956157462364864823458794572 34573485683465868234568613123749081377932457923457 93475897836587236458678234568234658362458762347895 68932456892346578636123846715376123475745723645666 38247687346128346812364812364816341384612384678345 76341236412783461278346781236481263489126348971238 41134681273467812364789
I do not want to represent my bigInteger in a higher base as it will not be possible to do conversion into higher bases with such a large integer.
I am making a project for school with visual basic and its a mcdonalds ordering system.There are 50+ buttons which you can press to remove an item and my code works fine. only problem is it is waaaaayyyy to long and can be shortened with a wildcard. Does anyone know what a good way to put a wildcard in the following code would be:
Private Sub btnsmallfries_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsmallfries.Click

View 7 RepliesI have a combo box that has a drop down list with long values in the drop down
Ex:
LB - Pounds
GR - Grams
When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows
LB - Pounds
GR - Grams
When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.

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?

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"
