2.0 Compilation Error BC30002 Type Is Not Defined

Jul 12, 2010

First of all, let me explain the situation, I know this is a bit complicated.
And I apologize for my poor English.I have created a dll library which contains the classes I created.I tested the library with Console Application and web site created with Visual Studio 2005,everything works fine.So I copied the dll to the "Bin" folder of a running ASP.NET 2.0 web site, added reference to the dll file, imported the namespace, then trying to initiate instances of objects in the dll.

Web Forms :: Error BC30506: Handles Clause Requires A WithEvents Variable Defined In The Containing Type Or One Of Its Base Types

Jan 26, 2011

I put a server side button on the header page. The website is running fine. I use the same source and put it on IIS, it's also working fine but the problem is, i couldn't compile it anymore using my VS studio. It's showing no error so when I go and check the output (after scrolling down a bit and found one line says error). it says

C:InetpubwwwrootAmFraserIntranetheader.master.vb(31,0): error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types.

C:InetpubwwwrootAmFraserIntranetheader.master.vb(32,0): error BC30451: Name 'keyword' is not declared.

keyword is the textbox on the header page. I also played around with AutoEventWireUp (true/false) and defining onclick event on the server tag but it is still not solving the problem.

DataSource Controls :: Entity SQL Error - 'CONVERT' Can't Be Resolved Into Valid Type Or Function

May 19, 2010

I have a SQL which is running good at SQL Server Mgm studio:

"select d.EmployeeID, CONVERT(VARCHAR(10),d.LogTime,111) as Date1, MIN(CONVERT(VARCHAR(8), d.LogTime, 108)) as FirstIn
from LogTable d where d.dwStatus=0 group by d.EmployeeID, CONVERT(VARCHAR(10), d.LogTime,111)"

However, When i put it into my code (Entity SQL):

"select d.EmployeeID, CONVERT(VARCHAR(10),d.LogTime,111) as Date1, MIN(CONVERT(VARCHAR(8), d.LogTime, 108)) as FirstIn
from IGPSiteEntities.AccessLogSet AS d where d.dwStatus=0 group by d.EmployeeID, CONVERT(VARCHAR(10), d.LogTime,111)"

I got error :

'CONVERT' cannot be resolved into a valid type of function. Near simple identifier, line1, column 200.

LogTime is a DateTime format e.g 05/05/2010 14:12:12

I want to select ONLY the Date (e.g 05/05/2010) and select ONLY the time (e.g 14:12:12) so i use CONVERT function.

Can't Convert System / Use Its Own Pre Defined Type?

Jan 14, 2010

So, I've been programming for a number of years. Finding some intricately asinine issues w/ ASP.NET and VB.NET as I learn them. How about this one:

[Code]....

The issue is not Date1
The issue is Date2.

No kidding. I had to String.Format Date1 for some odd reason, even though I'd already validated it. And, yes, I tried to parse and convert Date1 but I kept gettting the typical "Argument 'Date2' cannot be converted to type 'Date'." error. (Did you catch the copy & paste? I didn't edit it from my existing error, but Date2 should be Date1.) Yeah, that's the error I'm getting now with the above ...

"Argument 'Date2' cannot be converted to type 'Date'."

Date2 is a system defined type. Why can't the system convert and/or simply use it's own pre-defined type?

ADO.NET :: Linq To SQL In Web Project / BC30002: Type 'EntityRef' Is Not Defined

Aug 10, 2010

I have an ASP.NET 3.5 solution which has 2 projects in it: class library (data access) and the web project. The project has now changed and requires me to change the design and only have one project and move the class library into the web project. I have successfully moved most of the class library into the App_Code folder I created but continue to get an error when I run the program. The error is in regards to the Linq to SQL classes or dbml file. I continue to get a error:

Compiler Error Message: BC30002: Type 'EntityRef' is not defined.
Line 868: Private _CreateDate As Date
Line 869:
Line 870: Private _Code As EntityRef(Of Code)
Line 871:
Line 872: Private _Lab As EntityRef(Of Lab)

I have changed the dbml file to use the new connection string and modified any code behind by searching all the files in my project. But continue to receive this message. I've removed all the references to my old project and also removed any old .dll's which could have had references to it and continue to have the problem. Is there maybe a reference in my project I am missing or something else simple I have overlooked?

I should also mention when I move the .dbml file outside the App_Code folder (root of the website) and right click the project and select Convert to Web Application it works just fine.
