View 4 RepliesIO.Directory.GetDirectories() Finds Directories That Don't Actually Exist?
Jul 28, 2011The sub below will show all of the directories contain with a directory
Code:
Private Sub showDirectories(ByVal rootDirectory As String)
Dim rootDirectories() As String = IO.Directory.GetDirectories(rootDirectory)
[code]....
When I run this code I can use any directory as the root directory except My Documents.When I use the directory path with My Documents, as well as finding all of the folders contained in My Documents, it finds three extra: My Music, My Pictures and My Videos. Those three folders do not exist at all in My Documents. I have checked hidden files and folder and they are definately not there yet the showDirectories() sub says that they are.The exact error is: Access to the path 'C:UsersMichaelDocumentsMy Music' is denied.It's dened because the folder doesn't exist. I have checked myself using Windows Explorer!Despite this, when I type 'file:///C:/Users/Michael/Documents/' in the address bar of Google Chrome, it shows all of the files and folders in My Documents and, guess what, it shows the folders My Music, My Pictures and My Videos. But Windows Explorer doesn't show these! The strange thing is, for each of the folders, the last Date Modified was 23/01/2011 13:42:49 exactly. Each of the folders was last modified at that exact second simultaneously!I have 3 "ghost" folders "haunting" my My Documents. Is there any programs out there that perform "exorcisms" cause I am seriously freaked out!Perhaps this is the wrong place to post this. When I started writing this thread, it was about Visual Basic but now I realise it has nothing to do with programming at all.

View 5 Replies.net - Using Right Function In If Statement Causes Syntax Error
Mar 9, 2012I have a multiple-value-single-string as a parameter field in a report in Report Builder 3.0 (e.g. 20124, 20125). Now I want to split up this string, and show "Summer 2012" instead of "20124" and "Fall 2012" instead of "20125. I am using Visual Basic. Here is my two functions I have made in Report Builder 3.0 custom code. The error is in the second function in the "If Right(yearterm)..." line. It gives me a syntax error. If I write "String.Right" it gives me the error: "'Right' is not a member of 'String'". If i take out the whole "If statement" the report will run but "20124,20125" gives me this: ", 2012, 2012".

Call A Little Error Check Function ?

If isOK is true, the rest of the program runs. For some reason, when i run the test under conditions I know to be valid, or true, the function still returns isOK = false.

Function Calling Itself, Can't Dodge StackOverflow Error
Oct 7, 2011I understand that this is bad programming practice and redundant coding but I am curios.
I am simply counting a number up to 9999999 in a while loop. The Add() function simply increases that number and prints it out.
Inside the Add() Function I call the Add() function.
My program successfully prints out 12000ish numbers before I get a StackOverflow Exception.
So my question = Is there any way to ignore this error and keep counting?
I have tried On Error Resume, Try/Catch, and throw
My code is as follows.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
While number1 < 9999999

LINQ To EF Sum Function Error When No Records Returned
Jun 1, 2012Have seen some solutions for C# but do not know how to solve the issue in VB.NET.
Query:
Dim Query = (From t In myEntities.Bookings
Where(t.Ref = Someid)
Select t.People).Sum()
t.Ref field is an Int and so is t.People.
The SomeId value is the primary key of the related table. This issue is that there will not always be records in the Bookings table with a Ref value of Someid - so the query throws the following error.
I have seen others have got around this problem with catching the error, but from reading up on this and as per the error information it seems there should be a solution (in VB.NET) to cast the query or some of the fields in the query to nullable types?
Error is as follows:
The cast to value type 'Int32' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.
