Error The Type For Variable 'Index' Will Not Be Inferred Because It Is Bound To A Field In An Enclosing Scope
Apr 19, 2009
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').

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'm working with legacy data, which often brings me one information splited in multiple columns. I'm trying to reproduce the following SQL query.[code]This own statement will run into the following exception:Variable 'line' of type 'SomeTable' referenced from scope '', but it is not defined. Any directions? I'm trying to avoid magic strings, but I'm always giving up to it (as using HQL the concatenation expression + like function works like a charm).

I am experiencing a perplexing error ("Index was outside the bounds of array") that did not surface a few days ago WITH THE CODE UNCHANGED.
I was even able to successfully create an executable file a few days ago. It was therefore a shock to be given this error when testing it today.
The snippet is shown below:
Dim GearArray(lines.GetUpperBound(0), 8) As String For x As Integer = 1 To lines.GetUpperBound(0)
Dim parts() As String = lines(x).Split(",")

I have written a program and I think it is fine except for one error. "Variable 'intIndex' hides a variable in an enclosing block". i have a feeling this is something easy but have been trying to fix it and have failed miserably. I'm surprised I have any hair left!
the program is a simple hangman game that lets player one select a word from 1-10 letters and the other player needs to guess within 10 guesses.

I'm moving from VB6 to VB.net and there are a few things confusing. In vb.net, your program just automatically has a form, now the form in in a class and so it may or may not be there. In vb6, the main subroutine controls program flow and I don't see that in vb.net. However, my biggest problem is that I have a com dll that has a connect class with events. I need to be able to access these variable outside of that class. I don't understand how to do that. I can't seem to declare public withevents outside of the class and in the namespace so it can be shared with other code. Its say "not valid" in Namespace.
So what is the best way to do that. Do I create a set/get property for the class that holds this value? And, if I do that, is the connect class automatically instantiated as a part of the COM dll? Right now I don't instantiate the connect class, I assume the application does. But I'm not sure exactly how the property of the class would be set...perhaps I would need to call the property set from the on-connection method. Anybody know what the answer to these two questions are and this 3rd one? How can I have a variable that has "events" have scope across the entire project?

I have a public variable which seems to be going out of scope. I am confused as it has been dimensioned as a public variable: Public xlCell as As Microsoft.Office.Interop.Excel.Range
I originally had all my code in the same module in the same project and it was wrapped within a For/Next Loop (Example 1). I decided to clean up my code and make it more modular (Example 2). All the code is still in the same module in the same project.
Upon doing so, my public variable is not recognized in any of the private subs that I have created. I keep getting the following error: Message="Object reference not set to an instance of an object." When I test the variable using ?IsNothing(xlCell) in the Main Sub I get False in the main sub. this tells me te variable is recognized. However as soon as the Call SelectCaseSub() is triggered, I get a True value for ?IsNothing(xlCell). Why is this? Shouldn't this variable be in scope regardless?

I'm trying to create a simple media player that will scan a directory for certain filetypes, add them to a playlist then play a random playlist entry - changing every x seconds.I figured this would be simple in VB and, to an extent it was. I have the code running that chooses the directory and plays the random file.I just need to now make this repeat every 30 seconds or so.I have all the coded attached under the sub for the 'open' function of the player so it's quite flat. I think I need to use a timer here, to trigger the routine to pick and play the media every 30 seconds?In doing this I think I need to break the variables out of the function I currently have as they need to be shared between the timer loop function and the central 'creating file list' function.
I'm having trouble - I'm no coder (as you'll tell!) and although getting this far was easy I'm now (I think) bumping into threading / variable scope issues which are a bit of a brick wall.I've tried making the variables public / global by declaring in the class rather than the sub but I get errors at runtime. Presumably because of how I'm creating the windows media objects? [code]

where I should declare my variable when using forms and the scope in my test code.
In my code below I have declared variable x in my form1 which can be printed in form2.
But when I create a structure in form1, initialize an array of the type protorec and try to assign values to cards(1).firstname etc... I get a "declartion expected" error.
Why does it work for x but not for cards(x) my array of records?

I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?

I'm trying to format a datetime field to just show the date. The datetime is bound to an asp:label and for the Text attribute I have tried the following....
Text= String.Format("{0:D}", '<%# Bind("CReviewDate") %>')
and
Text= String.Format("{0:D}", <%# Bind("CReviewDate") %>)

In all cases I get a green wavy line under the equation and the tip help says "Validation (ASP.Net): If this attribute value is enclosed in quotation marks, the quotation marks must match.
String.Format("{0:D}", DateTime.Now)
is the syntax that I have been told should work.

I'm, using a SQL Server table in a DataGridView and I'm having trouble adding records. I'm new to vb.net but used vb6 for a lot of years so the transition is a little difficult. For now I'm just trying to add a record using a button click but the record key which is setup as integer and to automatically increment by 1 shows as -1 after the record is created. While the data does show in the grid it is never actually posted in the table. Once created I want to select the record just entered.
