View 16 RepliesHow To Make A Statement Run If All Conditions Are True From Multiple Condition Or If Statements
Mar 22, 2011I have a form that contains multiple conditional or if statements on several defferent for controls.
Example: Radio Buttons, TextBoxes and CheckBoxes.
I am intending to create an order form(demo) where the user can select multiple products.
I have a default order number that changes by one everytime an order is successful.
An order is only successful if all the information on the form is entered correctly.
My question is where do I insert the code for the order number?
Basically for the order number I have a counter that count by increment of one if an order is successful.
Meaning when the user hit place order, and all the infromation is right, then the order numer goes to 1 from zero.
Where do I add the condition for the order number since all the fields must first be completed.
Do I have to create a whole line of if else statements?
If Statement Doesn't Return
Mar 22, 2012Am I just being blind or does this If statement genuinely not do what it's meant to.[code]This displays the message box even though textSample is one of the letters. In my eyes that If statement should see that textSample is one of those letters and skip it, whereas if it was Z it would "Not" be equal to any of those and would therefore show the message box.
View 6 RepliesCan't Return Datatable Within A Try Statement
Mar 18, 2012I have the following piece of code that I am using to try and rip a csv file and turn it into a datatable. My problem is that the debugger never makes it to the return statement. Everything is appending to the datatable correctly, so I know that part works. Any idea's on what I can do to trouble shoot this further. Also, if you know of a simpler way to turn a import a csv file to a datatable I'd be very interested in learning about it.[code]..
It say that the Object reference is not set to an instance of an object. What's weird though is that it works through the whole data table fine. Could it be that the while loop is not terminating at the end of the file?

VS 2008 Return Statement In Function?
Apr 12, 20101. I would like to know why a Return statement is needed in the function in the first set of code, but not in the second(even though it still works with the Return statement). The functions are called the same way, so what is the difference?2. Why in the second code, the variable FutureValue is allowed to have the same name as the function? But when, in the first set of code, I try to rename the variable "discountPercent1"(in the function) to the function name "SetDiscountPercent", VB 2008 Epress gives the error message "The name conflicts with an existing symbol with the same name"?

.net - Will Sqldatareader With Using Statement Ever Return An Output Parameter
Aug 21, 2011Here's a simple code snippet of a larger function as an example.
Using conn as New SqlConnection("conn string")
Using find as new SqlCommand("ExampleProc",conn)
Dim rParam as new SqlParameter("@RESULT",SqlDbType.Int)
[code]....
I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.

Will Statements Or Expressions Execute After A Return Statement
Jan 29, 2010I was rooting around in one of our company apps which is done in VB.net. I'm not familiar with VB.net (I do stuff in C#) so I'm asking this question: Does the code after the clean up comment execute? [code]It is my understanding once you say return, you give the calling function control again.

If <expression> Then <statement [:statement]> Else [statements] In Concrete Form?
Jan 1, 2010I 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?

Get A Compiler Warning For Functions Returning Value Types, Without Return Statement
Jul 21, 2009I've just been burned again by the fact that there is no compiler warning when you fail to return a result in a Function that returns a Value type. I wrote the function:
Public Function CompareTo(ByVal other As MessageIndex) As Integer Implements System.IComparable(Of MessageIndex).CompareTo
Me._messageIndex.CompareTo(other._messageIndex)
End Function
which performs the CompareTo Function for two integers, then throws the result away and returns 0, because I forgot to either assign a value to CompareTo, or use Return, and that isn't flagged by the compiler because it's valid VB for a Value type.
I happen never to use "FunctionName = ReturnValue" because it hides information from maintenance programmers and also because I think it's insane .
Is there any way I can get the compiler to issue a warning whenever my Functions are missing a Return, whether it's a Value type or not?
