Valid Number Throws Overflow Error
Oct 6, 2010
I have a major problem. Things were going great until I came across this little bug(?) which has thrown a stick in my spokes. As I will demonstrate below, it seems that when defining certain numbers Visual Studio will throw an overflow error.
Dim T As ULong = 14774537964905701134 'Overflow error in the IDE
Dim M As ULong = ULong.MaxValue '(18446744073709551615) we are below the maximum value so it should work, right?
The one solution I have found is that we can use the following declaration instead.
Dim T As ULong = ULong.Parse("14774537964905701134")
However, to make matters even more complicated the value in question is unknown and must be compiled using CodeDOM so using the Parse method isn't an option. Unless there is some way I can determine if that value in particular will give me an overflow error.

I've ran into an overflow error when using a private sub and a random number generator...
Private Sub computerpicker()
Dim RandomNumGen As New System.Random
Dim rnum = (RandomNumGen.Next(3))
If rnum = 0 Then
rnum = (RandomNumGen.Next(3))
Call computerpicker()
[Code] .....
Even if bt1=0 and bt2=0 i still get an overflow error...

I've never seen this error before; and apparently (According to DIC) the number would have be bigger than -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, to this this exception (I'm using an Integer, but I've tried Int64, and the same thing happens).
This is where the exception is being thrown:
Dim localPort As Integer = (tcpRow__1.localPort1 << 8) + (tcpRow__1.localPort2) + (tcpRow__1.localPort3 << 24) + (tcpRow__1.localPort4 << 16)
Full Code (Method)
[CODE]...
I highly doubt that that the integer that is being parsed back is greater than, either of those numbers listed above. I've tried using Int64, and even removing the << operator, but it's still throwing this exception.

We have a VB application, which will get input from the user, post it to HTTP url and get the result from it, assigns it to objects and displays it to user.
In this flow, users are getting Run-Time error 6(Overflow). But this is not happening all the time. Iam not able to reproduce also?Would there be any other reason for this, apart from normal reasons like assinging a higher value to lower datatypes.

I'm trying to make a grade calculator that can determine the minimum grade you need to acheive a desired grade. I'm new to visual basic, and I'm trying to figure out why I keep getting the run-time error '6' message. I tried declaring the variables as variants instead of doubles to fix the problem, but it didn't seem to work. When I click "debug" the red statement is highlighted.!
Private Sub CommandButton1_Click()

could you tell me, why I get the stack overflow error on this code?
Dim ev As Double = datum.Year * 365 * 24 * 60 * 60
Dim honap As Double = datum.Month * 30 * 24 * 60 * 60
Dim nap As Double = datum.Day * 24 * 60 * 60
Dim masodpercek As Double = ev + honap + nap
The double datatype should be enough.

I have a program that sends out mass emails. My problem is that at the end of the program....I keep getting a "Stack Overflow" error and I cannot figure out where this might be happening. This program is a VB.Net 2005 console application which is ran manually from the command line. The code below that I have posted is what sends the actual email. I don't think it has anything to do with this error but my question is this. Do I need the highlighted line of code? I'm thinking I don't since the mail object is already being disposed...but I'm not positive.
Dim oEmail As New System.Net.Mail.MailMessage()
oEmail.From = New MailAddress(strSender)
oEmail.To.Add(strRecipient)

I have created an application using VB.NET in VS2008. When I run the app in the IDE on my development machine it works fine. It also works fine when I build it and run it as an exe on any machine that also has Visual Studio installed (at least 2005 and 2008 anyway) However, when I try to run the compiled executable on any machine without Visual Studio it throws up an error "[program name] has encountered a problem and will close..."

In our code base there is a function which should return either an object or nothing. The exact code is this : Return NothingThe calling method looks something like thismyObj = theClass.function()if myObj <> nothing then // fails

I am trying to get the selected rows from a listview. To achieve this, I did this:
Dim numsel As Integer
numsel = Me.ListView1.Items.Count
For countme As Integer = 0 To numsel
[Code]....
It does count the selected rows, but it always throws out the error saying "ArgumentOutOfRange Exception", or something along those lines. For example, if I selected a row, it will output the results of that row. But the loop goes on. I tried everything I can but to no avail. I specifically want to select multiple rows, and I can achieve that if someone can assist me with this simple "problem" I have.

I recently upgrade a project from vb 6 to 2008. Most of the code runs fine.I have a webbrowser form control that I use to navigate local files and display them with. (i have a file list box that you click which calls the navigate of the browser control). Most file types i have test work fine and display just as they would in a real browser window. Excel, PDFs, etc... so examples of files that utilize "plugins" like acrobat reader inside the browser work great. Tiff files are the exception. No error is thrown in vb, but the browser throws 2 runtime errors, included at the end here. After the browser errors are ignored the program continues execution but will just not display the file.
i can type the path to the file (eg c: estfielsfilename.tif) in a regular browser window and it displays just like it should, inside IE, using a plugin.Prior to upgrading, depending on what was installed on the computer, navigating to a tif would open the tif with picture and fax viewer, or display it with a tif viewer plugin.

If dgCell = "Delete" Then

[Code]....
Error is thrown at "cmdDelete.ExecuteNonQuery()". Sql query still deletes the record. I have run query against the database itself and I get no error. I am using an as400 db and vb.net 2008. I'm not sure if this is problem with the database or vb. I get this error when I run the delete above, also when I run an insert or an update.

I am new to VB. I was trying to insert a record into access database with data reader. I was getting OVERFLOW error at runtime. My understanding is that overflow error occurs when we assign values that to variables that exceeds the maximum size of the data type.
Following is my code
Private Sub InsertRecord(ByVal CustomerID As Integer)
Dim RowArray() As String = Split(Me.lblRow.Text)
Dim intPrice As Integer
Dim decTotalPrice As Decimal
Dim mySQL As String

The application that I am working on is a Service Desk App. I have a form there that uses a DropDownList that contains employees names coming from the Active Directory. Any employee can make a request and save it. Problem arises when an employee leaves the company and consequently his account is deleted from the Active Directory. When some other employee searches the DB to finds a relevant Service Ticket that could be of his use, when tries to open it an error is thrown that indicates that the name does not exist in the DropDownList items.
UPDATE:I am adding some code so that it can be more clear.

I am attempting to list files within a folder on an FTP site. When I run the debugger, I get a clean run the first time with no problems. Subsequent attempts lead to a 550 error: "The remote server returned an error: (550) File unavailable (e.g., file not found, no access)." However, If I step through the process in debugger, It works fine. I'm thinking this is a timeout issue because there are many files within the folder. Any suggestions?

The application was previously using GlobalMemoryStatus() and MEMORYSTATUS structure to retrieve memory information. But since, the Physical memory of the hardware in which the application runs is more than 2GB, the code was changed to use GlobalMemoryStatusEx() and MEMORYSTATUSEX structure. When this function was implemented and the struture was used its thrown compilation error: "error C2501: 'MEMORYSTATUSEX' : missing storage-class or type specifiers"How to solve this issue???
