Web Forms :: Log Out Button Not Working - Returns Error BC30506
Feb 7, 2011
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 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.

I have an ImageButton which sometimes returns the wrong coordinates when clicked. So far I have seen this problems only on one particular computer but on that system it is consistently out by a factor of about 1.25. The dimensions of the ImageButton are 300 x 450 but clicking in the lower left corner returns 374,562. However, if I raise a button click through code the correct region of the button is accessed and the correct coordinates can be recovered. The browser is IE running under XP SP3. On other computers with the same browser and operating system there is no problem but I don't know how widespread the problem could be. It is not affected by altering the screen resolution. Has anyone encountered this before? Is there a way to test and calibrate an imagebutton (without asking the user to click somewhere special first)?

Like Windows' environment Openfiledialog control, is there any way that I can create a file browse button that will let me select a file and return the path and filename to a variable or a textbox or any other object?
The webform will contain two controls: a regular button that I will use to browse and select a file, and a gridview.that will display a list of the files that I've selected with the file browse button.

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

I searched many posts in this forum and could not find good answer ,I almost tried all the suggestions in this forum for similar issue,So please don't say there are many posts to refer in this forum.Iam trying to fax a pdf document which is auto generated by the ItextSharp tool.Iam using ItextSharp PdfWriter for generating a pdf ,which writes the pdf in a file.Until this point everything is ok,I get the pdf document as expected.What would like to do is to send this pdf via email or fax based on the user input.Iam fine with sending this pdf as an attachment to the user's email.Problem arises is when iam trying to send a fax.I am using the input text value as the Receipent Fax Number(Right now iam concentrating by giving a valid fax number).Iam using the below code for faxing the document and receive the below error.
String number=txtFax.Text.ToString().Trim();

I just created a small site with form authentication with route handling. Without forms authentication, the pages route just fine. With forms, it returns back to the login page as it is not one of my allowed locations specified in my web.config file.
I know I probably need to write a custom route handler. Does anyone have an example I can follow for this?

When I run my website on local server asp.net routing works very well, but when I deploy it on a remote server ( asp 4.0 integrated pipeline ) it always returns with 404 error.
My url route is very simple, a stored procedure gets image's id and then displays it.
Global.asax:

Default.cs:

I think I might be missing something obvious but I'm not sure. The other day I was trying to run throught the windows live ID domain verification process on my asp.net mvc site. Part of the process requires you to download a text file and put it in the root of your site which your domain points to. When I would click the verify button in the windows live app verification process it would fail. In a browser, I could hit the request the text file and get a 200, which puzzle me. I then used this site http://www.internetofficer.com/seo-tool/redirect-check/ to check for any redirection issues. Suprisingly when I enter in the url to check, in my case http://www.whatitcoststobeme.com/741KXPjf42zgZRnV6O1LsO92.txt, it returns a 500 error. I ran this same test against a non-MVC site and the verificaton process passed plus the redirection checker return a 200 ("direct link" on their site). The environment this was tested in was IIS7.
why this is happening with static content on a ASP.NET MVC site? I want to say it's something to do with the url routing handlers.

I have a wcf service that randomly begins to fail when requesting the autogenerated javascript that wcf supports making. But I have no luck tracking down why. The js thing is part of the wcf featureset, so I dont know how it can suddenly begin to fail and be unable to work until IIS is recycled.
The http log gives me:
2010-06-10 09:11:49 W3SVC2095255988 myip GET /path/myservice.svc/js _=1276161113900 80 - ip browser 500 0 0
So its an error 500, and that is about the only thing I can figure out. The event log contains no information.
Requests to /path/myservice.svc works just fine. After recycling IIS it works again, and some days later it begins to fail until I recycle IIS.
<service
name="path.myservice"
behaviorConfiguration="b">
<endpoint
address=""
behaviorConfiguration="eb"
binding="webHttpBinding"
contract="path.Imyservice" />
</service>
...
<endpointBehaviors>
<behavior name="eb">
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="b">
<dataContractSerializer maxItemsInObjectGraph="2147483647" />
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
I dont see any problems in the web.config settings either.
Edit:
Just to make it clear - It is the generation of javascript that fails, my code is never invoked. Calls to the service works just fine.

I'm experiencing a really confusing error. Exactly every other time the page returns
ERROR [23000] [DataDirect][ODBC Progress OpenEdge Wire Protocol driver][OPENEDGE]Integrity constraint violation:uniqueness constraint violation (7518)and else it works nicely.
Here's the SQL:
SELECT SlsOrder.Orderdate, SlsLine.LineNum, CASE WHEN SlsLine.AllDelivered = 1 THEN 'X' ELSE '0' END AS 'AllDelivered', Item.ItemName, Item.TechName, SlsLine.IntDlvDate, SlsLine.OrderNum, SlsLine.ItemCode, SlsLine.Version, CEILING(SlsLine.Qty) AS 'Qty',

I have a webservice (ASMX) which I have tested locally using built-in VS web server. It works fine in the Dev environment, and there was no configuration of anything in IIS for this kind of webservice to work.
Today when I deployed my site on the live server, I got a 500 error when the webservice is being called. The website doesn't work, and unfortunately the client did not test this on staging (same server)
Here's the sample call to my service.
$.ajax({
type: "POST",
url: 'http://www.mydomain.com/services/someservice.asmx/MyMethod',
data: "someid=564",
dataType: "xml",
success: function(msg){
}
In Firebug, http://www.mydomain.com/services/someservice.asmx/MyMethod returns error 500 internal server.
I called the service using jQuery AJAX, the live server is Windows Server 2008 Standard.

I have a routine that submits a SOAP request using HttpWebRequest and WebResponse. If the SOAP Request fails the server sends back HTTP/1.1 500 Internal Server Error. When I trap the error I have yet to find a way to view the body of the reply which contains the fault code. Is there a way to retrieve the message body when the server returns a 500 internal Server Error? In body of the reply which I am not able to retrieve.
faultstring xml:lang="en-US" Specified argument was out of the range of valid values.

In my asp.net web site I have custom error pages defined as following in my web.config file.
<customErrors mode="On" defaultRedirect="~/defaulterror.htm" >
<error statusCode="404" redirect="~/404.htm" />
When file is not found it correctly display 404.htm page but the issue is when I do Fiddler trace it returns 302 as HTTP status code.This is a big issue for search engine page indexing due to this lot of broken links still have been indexed recently because of this in my web site. how can I prevent returning 302 as HTTP status code for file not found errors and return 404 for file not found errors.I am using asp.net 3.5.

I have an ASP.NET page (using ASP.NET AJAX and the Telerik RAD components) that provides a data table and an option to download data in CSV format.I have a requirement that a single button allow the user to download a data set. I have a system set up that's nearly working for me based off the solution in
http://stackoverflow.com/questions/104601/asp-net-response-redirect-to-new-window
<asp:Button ID="ExportCsvButton" runat="server" Text="Download to CSV/Excel"
byte[] csvBytes = someLongOperation();
Session[EXPORTED_SESSION_KEY] = csvBytes;
Response.Redirect("myexportpage.aspx", true);
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.AppendHeader("content-disposition", "attachment; filename=" + "file.csv");
Response.ContentType = "text/csv";
Response.AddHeader("Pragma", "public");
Response.BinaryWrite(Session[OtherPage.EXPORTED_SESSION_KEY] as byte[]);
Response.Flush();
Response.End();
}
This actually works quite well. When I click the 'Export to CSV' button, the page's UpdateProgress kicks in and my loading overlay appears (it's a CSS div that covers the window when visible). This can take some time depending on the data set (potentially several minutes), at which point I'm getting a window popup with my file.

I am using a web form in vs2010 and in my form am having a gridview with button on footer. I have written the code to create a new row while click the button. If I click the button i got the following error
"unable to cast object of type 'system.web.ui.webcontrols.textbox' to type 'mysite.textbox"....
Below is the button click code.
private void AddNewRow() {
int rowIndex = 0;
if (ViewState["CurrentTable"] != null) {
dtCurrentTable = (DataTable)ViewState["CurrentTable"];
DataRow drCurrentRow = null;

Hoping someone can point me to a solution, haven't been able to find one yet.
I'm using the standard way for send HttpWebRequest
[Code]....
As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.
Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.
Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.

In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.
I used below code for above:
C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
[Code]....
problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:
Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"

OK, I'm sorry if the tile of the question was unclear, and if you understand what I mean, please don't hesitate to help me think of a better one.
Anyway, I have a <input type="submit"> element for my form, and I want it to return the same URL as the URL of the page the element is on.
Currently, if I click the button, it takes me from /Calculate/Quadratic to /Calculate/QuadraticForm
In my controller for this view, I have the following code:
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Quadratic()
{
ViewData["Root1"] = "";
ViewData["Root2"] = "";
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ViewResult Quadratic(QuadCalc boss)
{
ViewData["Root1"] = x1;
ViewData["Root2"] = x2;
return View();
}
And here is the markup and code for my Quadratic view page, which includes the form which includes the submit button I've been referring to:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Quadratic</h2>
<% using(Html.BeginForm("QuadraticForm", "Calculate")) %>
<% { %>
<div>
a: <%= Html.TextBox("quadraticAValue") %>
<br />
b: <%= Html.TextBox("quadraticBValue") %>
<br />
c: <%= Html.TextBox("quadraticCValue") %>
<br />
<input type="submit" id="quadraticSubmitButton" value="Calculate!" />
<br />
<p><%= ViewData["Root1"] %></p>
<p><%= ViewData["Root2"] %></p>
</div>
<% } %>
</asp:Content>
Therefore, all I really want is to have the submit button return the same page, but the HTTP post will aid the application in passing new ViewData. Unless I'm interpreting this all wrong.

well it returns error no overloading method for select (P.S. same code work fine for insert)
