Invalid Column Name 'LastEditDate' - SqlClient Exception?

Nov 16, 2009

I am getting an exception and I don't know how to remedy it. The history is that, in my inexperience, I had asked for the creation of an ODBC data source using a remote SQL Server, and specified caching of certain tables.Then I noticed that this was getting complicated and I tried to not have those tables cached.Columns like 'LastEditDate' had gotten added to those tables.I abandoned using ODBC and went with SqlClient instead. I started getting the error described below re "Invalid column name 'LastEditDate'" even though I never refer to or use such a column. I searched my computer for files containing this string and deleted them. The error kept occurring. I removed all the columns called 'LastEditDate' from the SQL Server database. The error kept occurring. I started my Visual Basic.Net 2008 project over with a different name.The error still keeps occurring.Fragment from a class (form) containing a sub called SyRefresh:

Case "STOCKDATA"
sCell = sData.Split(",")[code].....

dc is a datacontext associated with a SQL Server instance on a server somewhere on the Internet.That remote SQL Server is version 2000. As you can see above, I use Linq.

Invalid Cast Exception On Same Type?

Apr 15, 2012

i know this may seam odd but I'm getting an error navigating through a datagrid of an invalid cast. The trouble is it is of the same types!! I working on customising some Sage code and in the form there is a datagrid that is populated by a series of Sage.Accounting.Stock.TraceableSOPAllocationItems (a batched stock item allocated to an SOP).

I want to give the user some further information on each item so they can decide which batch and bin to use. I want to go through each item in the grid and then go find this extra information for it. the trouble is when I go to navigate through, My VB.Net code throws the error.InvalidCastException was unhandled by user code, Unable to cast object of type 'Sage.Accounting.Stock.TraceableSOPAllocationItem' to type 'Sage.Accounting.Stock.TraceableSOPAllocationItem'.

That type should be of CharacterController which is defined as a child of Behavior so why wouldn't it let me cast that?

Error : Invalid Cast Exception Was Unhandled

Aug 15, 2011

I am getting Invalid Cast Exception was unhandled.Conversion from String 'abc' to type 'Double' is not valid in the following line!

If
((xlBook.Worksheets(2).Cells(iRowIndex, iColumnIndex).Value)) = avFoundKeywordds(iSearchText)
Then

The business intent is that user enters the keyword 'abc' and clicks search button . We have defined different keywords in a xls which has 1600 rows and 16 columns . so when finding abc in any of the cells ,it has to return the value of a column#4 where the name is specified !

VS 2010 - Masked Textbox (Invalid Cast Exception)

Oct 10, 2011

I've got a masked text box that throws an invalid cast exception if I try to put anything in the TextChanged event:
Private Sub mtbZVal_TextChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MaskInputRejectedEventArgs) Handles mtbZVal.TextChanged
MsgBox("OK!")
End Sub

Even more oddly, it throws the exception in a completely different part of the program. The masked textbox is on a form that opens when you press a button, and that's the bit that gives the error:
Private Sub cmdAddLoc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddLoc.Click
If frmLocation.ShowDialog() = DialogResult.OK Then
End If
End Sub
