May 13, 2009I'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
Value Of Type 'System.Linq.IQueryable(Of Integer)' Cannot Be Converted To Integer?
Aug 11, 2011I 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?

Feb 21, 2012I declare my dates as the following in my code:

Here is my exact code. There error is Input string was not in correct format:

View 4 RepliesSet A QUERY Filter
Dec 26, 2010I used the data wizard to create a binding source, and table adapter, etc. I have a form and I have the fields on the form. All is good. The data is loaded via the .FILL method using the DEFAULT FILL,GetData() funtion created by the wizard. All is good. Now I want to filter out some of the records so I created a new FILL method (using the data source editor).
It is called FillByCountry() and the SQL statement looks like this "Select * from StampCollection WHERE Country = "Canada". Simple enough and when I test the query, I get what I expect. Now - suppose on the form I have a button and I when the user presses the button, the filter is enabled. So when the form loads, I have the standard lines to load the data... StampCollectionTableAdapter.Fill(SCDBDataDataSet.StampCollection)

SQL DataBase Query / Filter At Runtime
Oct 28, 2011I'm trying to access the SQL DB I have designed within my project in Visual Basic 2010 (.NET code seems to work for me 99% of the time) at runtime so that a user can select a method by which to filter a DataGridView.I have a fantasy football draft application that fills the DGV from a Table Adapter. The database is named NFLPlayerDataBase.mdf, the dataset used to fill the DGV is TabNFLPlayers11BindingSource1, the table adapter is TabNFLPlayers11Table Adapter1. The DGV is dgvDraft. Idk if that helps at all.If the user wants to look at only RBs while making their draft choice, I want them to be able to select RB from a drop-down and have the DGV be filled with the query that selects only RBs from the table. I have the drop-down already set and am able to fill in the DGV when the form initializes. I just can't get it to fill with the query request for a specified position.The table I'm looking to use from the .mdf is tabNFLPlayers11 and the column header that will be searched through the filter is "Position." Options are QB/RB/WR/TE/K/DST and will be selected by the user from a drop-down.I cannot find a way to even open the connection whenever I change the value of the drop-down.
