Program Function - Says, "The Type For Variable [variable] Will Not Be Inferred Because It Is Bound To A Field
May 18, 2012
Public Class Form1
Dim x, c, number(0 To 19) As Integer
Dim s As Integer
[CODE]...
The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.
-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.

I have some code and there are 2 errors which I don't understand I have tried all sorts...
1)The type for variable 'Index' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'Index', of use the fully qualified name (for example, 'Me.Index' or 'MyBase.Index').
2)Function 'GetNewPhrase' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used.
I can't get it to work..

This program was created with vb6 to find and remove empty folders. i converted this program to VB.NET code and it isn't working like it should.. it seems to stop scanning at 'C:\documents and settings' instead of scanning other folders in other directories...Does this code look right? I can provide the entire program if needed... I just want to know why it isn't scanning like it should. Btw im switching from vb6 and trying to learn vb.net.. vb.net is a lot different..
Private Sub ScanForEmpty(ByRef vFolder As String)
Dim nSize As Integer
System.Windows.Forms.Application.DoEvents()
If bExit Then Exit Sub

I get this message at the bottom:Warning5 The type for variable 'FolderObj' will not be inferred because it is bound to a field in an enclosing scope. Either change the name of 'FolderObj', of use the fully qualified name (for example, 'Me.FolderObj' or 'MyBase.FolderObj').

I have the following code that I am using to parse out a test file. I am getting variable conversion error in Sub Main() when I assign file = Read(). The return value of Read() is a TextFieldParser type. How do I assign the proper variable type to "file" so I can write the output to a text file?
Function Read()
Using MyReader As New FileIO.TextFieldParser("C:UsersColinDesktopParse_Me.txt")

I have this function:
Public Sub DoStuff(ByVal type as System.Type, ByVal value as Object)
End Sub
The 'value' argument is always an array of the same type as 'type'. How can I loop through the values of the array?
I'd like to be able to do something like this:
DoStuff(GetType(Integer), New Integer(){1,2,3})
Public Sub DoStuff(ByVal type as System.Type, ByVal value as Object)
//Strongly types arr as Integer()

So, let's say I have this code (VB.Net)[code]...
What I don't like is:
- relies upon reflection
- loosely typed (no compile time checking)
- I'd rather store the binding information somewhere other than ID, but don't know where else it could go within the aspx definition. Moving the binding declaration to the code behind would be better in some ways, but worse in others.

I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.

I'm aware that questions like this have been asked before and I doubt it's possible, but I just wanted to make 100% sure that it isn't.In VB.net or C# (either language, it doesn't matter), I want to cast a variable to a type represented by another Type variable. Here's an example of the kind of code that would be needed in C#:
Object castMe = new Foo();
Type castTo = typeof(Foo);
Foo beenCast = (castTo.GetRepresentedType())castMe;

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.

I am working in a form, and I had to this
Dim par1 as string = "something"
I want pass par1 to update sql statement, and I am not using AddParameter So, I had to add single quotes, the par1 will be
par1 = "'" + par1 + "'"
instead of doing the above, I was thinking in
par1 = par1.ToString.AddSingleQuote
or
par1 = par1.AddSingleQuote
Either to add "AddSingleQuote" to "ToString" method, or make it available for every variable of type "String" Can that be done?

Writing an asp.net mvc app and i have something like this...
Public Class AA
'... has some variables...
End Class
Public Class BB
[code]....
So, now in my program, i just want to copy object of type AA to an empty variable of type BB?it makes sense to do this, as i expect all the fields in AA type object to be copied to the newly created BB type object, and the ExtraVariable in the BB type object i would (will) just assign a value to it later (after the copy) on my own time!!I know copying BB type to AA type would not be appropriate as there would be lost data!But im trying to copy AA to BB, I've used both DirectCast and CType to do this, and i keep getting "unable to cast" error!
Note: I'm using vb.net (but can read c#, no problems)

I just started using VS2010. I am very familiar with Visual Basic 6 and was very comfortable with it.I was able to take a variable and assign a database field to iwithout using data binding. I can't seem to figure out how to do thatin VS2010 What I am trying to do is have the use enter a password to gain access to the program. The password is stored in a database so that the user/owner can change this password to suit their preference.

Upon entry into my database, frmLot opens. The form opens in datasheet view. It displays several fields to include one named WorkOrder. The user clicks in the cell named WorkOrder. In the On Click property, I store that variable and name it stWorkOrder. What I need to happen then is to pass this variable to the criteria field of a query named qryWorkOrder and have it run and display results.

I have a list with several fields that is created from dataset from a linqtosql query. At run-time, the user gets to specify what field he/she wants to display from the list. In other languages, I can dynamically do this like:
valueIwant=mylist(i).[fieldnameImInterestedIn]
Where 'fieldnameImInterstedIn is itself a variable. How do I do this in VB.Net?
non-working actual code follows:
Dim patientdata = (From patientvar In pdfdatacontext.tbPatients Where patientvar.PatientID = patientid)
Dim patientlist = patientdata.ToList()
fieldvalue=patientlist(0).(reportrow.userselectedfieldname)

I know that
Public Incognito As Boolean
is a variable called "Incognito" that is class-wide that is a boolean.My question is that is there a form-wide variable form that can like communicate with different forms. So if a variable in form1 is "True" than, how can you make a variable in form2 turns to "True" too?

I have some code like:
Lookup(Of String)("Testing")
Lookup(Of Integer)("Testing")
And both of those Lookups work great. What I'm trying to is call the appropriate LookUp based on the type of another variable. Something that would look like...
Lookup(Of GetType(MyStringVariable))("Testing")
I've tried to Google this but I'm having a hard time coming up with an appropriate search.
