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.

Just knocked up a quick sub site and everything was working great until I put my code in the getquote button and now it shows the below error. Done a bit of searching but everything I find says I need to insert something like: Protected WithEvents {buttonname} As LinkButton

return from c in db.TBLcharacters join o in db.TBLjobs on c.char_job equals o.job_title orderby c.char_lastname descending select c;
The goal is to print out the job title from the seperate table when I list the names of the Employees. So in the final formatting on the view it would be John Doe [Janitor] (or something similiar)
But when I make the build I get the following error:
The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'Join'.
What I find wierd is cjar_job and job_title are both varchars so the type is the same.
have been trying to get to grips with the entity framework using the music store tutorial as a base reworking it to fit an existing application i havei have a database table called AuthorDetail. I also have AuthorDetail.cs Model, and a View AuthorDetail.cshtml strongly-typed to the Model. It's also declared as DBSet in the Entities class :DbContext under the application Models namespace.
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.
I have a log-in panel that when a user is logged in will show a Log Out button. Only problem is when I go to debug I get the error message:
"error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types."
This is my back-end code:
[Code]....
And this is the front-end:
[Code]....
The log-in button works fine and I was just wondering if any of you could spot what is wrong as it looks like it should work perfectly as it is the same as the log in button.
I added a web reference to a web service to my web project. I can add an instance of the web service in my code and everything appears to work fine. But if I try to debug my code I get a complie error stating that the Type is not defined. What am I doing wrong?
Description: An error occurred during the compilation of a resource required to service this request. review the following specific error details and modify your source code appropriately.

Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.
Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.
So, am I doing something wrong or is this a limitation.
I have a base user control (inherited from System.Web.UI.UserControl)
public delegate void MyEventHandler(object sender, MyEventArgs e); public event MyEventHandler ControlLoaded; //Fire the event from here protected override void OnLoad(EventArgs e) { MyEventArgs cmdEventArgs = new MyEventArgs("somearg"); ControlLoaded(this, cmdEventArgs); }
I have several controls that are derived from this base user control.
On the host ASPX page, I need to subscribe to the ControlLoaded event.
protected void Page_Load(object sender, EventArgs e) { //subscribe to the event //This line DOES NOT WORK as I cannot attach event to a base control - It needs an instance of the user control which I don't have BaseUserControl.ControlLoaded += new MyEventHandler(ControlLoaded); } private void ControlLoaded(object sender, MyEventArgs e) { // some control has been loaded }
However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.
I get a message - "Function without an 'As' clause" for HMAC_MD5 and "Variable declaration without an 'As' clause" for Key and Value. But the code works. But the messages still exists. Is there a way to fix this to avoid the messages?
I can select IQueryable<object-type> data fine from a data repository class and push it into a list type MVC view, but how do I do this and group that data - I don't seem to be able to find any examples on this.
to define a variable/property of more than one type. Let's say i want a property TextWebControl that is a WebControl and also implements Web.UI.ITextControl(f.e. like a TextBox or Label). But i don't want to enforce that it is a TextBox or Label, but only one that inherits from WebControl and also implements ITextControl so that it also would work with controls added in future releases of .Net-Framework.
.Net-Framework 4.0
Edit: I have retagged the question and added VB.Net because it's my default language. Normally it's no problem for me to understand C# also, but i must admit that it's difficult to translate generic stuff to VB.Net without experiences and it's also better documentated in C# than in VB. So i would appreciate(and aceept) a working example of a VB.net generic type of ITextControl/WebControl.
From Marc's answer i understand that i need a generic class. But how do i instantiate it in SomeClass? This won't compile:
Class SomeClass Public Property info As InfoControl(Of WebControl, ITextControl) End Class
Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?
I know that the problem is my field having NULL values. However, I don't know how to have it process the code even if the field have nullshere's my code:
I am not able to understand what is the problem with My sql ..as same query is run sucessfully while i use SQL Server 2005 whit out any Exception or error.........
Select Count( Date ) From Attendancemaster Error in SELECT clause: expression near ')'. Unable to parse query text.
