Integer Cannot Be Converted To 'System.Data.DataSet'
Mar 19, 2011
I am trying to insert a small message of 150 characters into the "AdvertisingInfo" database into the "QuickPost" column. Right now there is only one row that will have various columns updated by several forms.I just started to teach myself VB10 and it has taken me 6 hours to get this far. I'm tired of trying today and am going to bed, but I need help trying to figure this out. I keep getting the error: Value of type 'Integer' cannot be converted to 'System.Data.DataSet'.[code]

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?

When I try and compile code in vb.net 2008 I get an error that says "value of type 'system.drawing.image' cannot be converted to integer. The error happens at piccolor.image
GetDIBits(Form1.PictureBox1.Handle,
picColor.Image , _
0, Form1.PictureBox1.Height, pixels(1, 1, 1), _
bitmap_info, DIB_RGB_COLORS)
Here's the code that explains what piccolor.image is, it's a picturebox on form1 that has an image
readpic(Form1.PictureBox1)
Public Function readpic(ByVal picColor As PictureBox)
GetDIBits(Form1.PictureBox1.Handle,
picColor.Image , _
0, Form1.PictureBox1.Height, pixels(1, 1, 1), _
[Code] .....
And Imports System.Runtime.InteropServices is on the top of the module, if u need more code then let me know. Also I wonder if there is a way to bitblt directly to a pixel array.

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 tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

I am trying to perform a simple bound connection between an Access database and a text box on a form. This is actually Chapter 18 of the "Microsoft Visual Basic 2008" book.I get the same error message when trying to create my own project "MY ADO Form" or the "ADO Form" project supplied from the DVD provided with the book. I am running the 90 Day Trial Version of Visual Studio 2008 with SP1 and Net 3.5 SP1.
My operating system is the 64 bit Version of Vista with all updates.The error when I try to run the application in the debug mode is:"A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll"and as a result no data shows up in the text box from the database and the data selection bar is grayed out in the form. The underlying database "Students Data Set" appears to be fine as I have seen the correct data for the fields "Instructor" and "PhoneNumber" prior to running the program and when connecting with the database.
