VB Integer Into SQL Server 2008?
Feb 13, 2012
I am trying to write two integers into an SQL Server 2008 database.
QuizID and Answer have their data type in SQL set as 'int' and Question is 'varchar'. ReadQuizID and FinalAnswer are integers. When I run this code to write to the server I get an error saying "Conversion from string "Insert Into Questions(QuizId,Que" to
type 'Double' is not valid.".
myCommandWrite.CommandText = "Insert Into Questions(QuizID,Question,Answer) Values('" + ReadQuizID + "','" + FinalQuestionString + "','" + FinalAnswer + "')"
If I replace the string with:

ive got some simple problem i cant understand how to solve.
str(1) is an array and integer(or double, tried both)
a(1) is an array and integer (or double, tried both)
a(1) = a(1) + 1
Label1.Text = str(1) + a
the big part is where i get: operator '+' is not defined for types 'integer' and '1-dimensional array of integer'.why do i get that message and what does it mean? how do i make the code do what i want?

I faced an error when upgrading VB6 code to VB.NET. The error occurs at AddressOf WindowProc
AddressOf expression cannot be converted to 'Integer' because 'Integer' is not a delegate type
My declaration for SetWindowLong is:
Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA"(
ByVal hWnd As Integer,
ByVal nIndex As Integer,[code]....
What is the reason for the error I get?

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
Do While Not item Is Nothing
item = item.NextItem
Loop

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.
After the conversion, the code look like this:
Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer
[Code]...
Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

I have a LINQ2Entity problem, I want to get the value, string, from a database, so I select FProducts.Serial_number, and to end the query, I do .ToDictionary. The problem is, it tells me that it doesn't have sufficient parameters, to convert ToDictionary. So I need something like select FProducts.Serial_number, Nothing). ToDictionary. Also FProducts.Serial_number, 0).ToDictionary doesn't work.
Sub GetStatistics(ByVal ProductNumbers As List(Of String), ByRef Passed As Integer, ByRef FailedProducts As List(Of String))
Passed = 0
FailedProducts = Nothing

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:
Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)
[Code]...
I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

This is giving me a headache. I have this link query here that grabs an ID
Dim mclassID = From x In db.SchoolClasses Where x.VisitDateID = _visitdateID Select x.ClassID And then later on I have this linq query
ViewData("Staff") = From t In db.Staffs Where t.ClassID = mclassID Select t
I've tried quite a few things but to no avail. I've attempted casting, converting, Is operand, etc.

I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.

I'm just writing a bit of code to compare an id of integer with an id of integer? for example:
Dim id As Integer = 1
Dim nullId As Integer? = Nothing
Dim areEqual As Boolean
areEqual = nullId = id
When I try to compile the code I get a compiler error: Option Strict On disallows implicit conversions from 'Boolean?' to 'Boolean'. Whilst it's very simple for me to work around this, I was hoping that someone might be able to explain what's going in the compiler to give this warning.

I am making a simple timer but I seem to be having some troubles formatting the time. What I have done is split up the hours, minutes, and seconds into integers. The problem is, I do not want my minutes and seconds to be 1:1 for 1 minute and 1 second. Instead I would like it to be formatted mm:ss.What command is used to format and integer to add a preceding 0 or not?

We are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.
