Unable To Evaluate Expression Because Code Is Optimized Or Native Frame Is On Top Of Stack?

Feb 16, 2010

I understand that if you put a Response.Redirect inside a try-catch that you're going to get this error unless you specify the 2nd param of the redirect as false.But even looking at this article (PRB: ThreadAbortException Occurs If You Use Response.End, Response.Redirect, or Server.Transfer) I still don't understand why I have to set this to false for this particular line of code...we've always had true for that param until I wrapped that in a try-catc

DataSource Controls :: Cannot Evaluate Expression Error After Converting VS 2003 Web Application To VS 2008?

Jul 8, 2010

I recently converted a web application of ours to VS 2008 so that we could upgrade to .net 3.51 framework.

I have been making some changes to the layout, to take advantage of ajax and minimize the amout of data needing to be loaded and the number of postbacks processed.

The problem I am having is when I try to save the data.

The page postback calls a local Sub which reads the form data into local variables and then passes these variables to our assembly.

The primary assembly has 70 parameters which are used to populate one of the tables in our database.

So I have 70 local variables just for this call plus a variable reference to the output of the assembly which contains a property for each of the columns in the associated database record.

There are some additional assemblies called to update other tables so, in all there are 121 locally defined variables in this sub.

Bear in mind that this sub is called from the page load event which has 93 of it's own locally declared variables.

Here is what is happening, when I run the code I am using cdate() to convert the value of a text box to datetime and pass it to my assembly. When doing so it throws a conversion error.

So I created a local datetime variable and converted the value of the control to the datetime and passed the variable to the assembly.

No more error, but the proc did not save the data as it was supposed to.

What I noticed in debugging, on the locals tab, is that every local datetime variable displayed the following message:

Cannot evaluate expression because we are stopped in a place where garbage collection is impossible, possibly because the code of the current method may be optimized

I also noticed that on the watch window the same message would display if I attempted to reference any of the datetime controls on the form.

There are only 3 variables and 3 datetime controls that appear to be affected. the controls are all html input boxes. Every other variable and control on the form behaves normally and I can see their values while debugging, it is just these six that are exhibiting the problem, whats more is that they are not new controls to the form.

Asp - SmtpClient.Send Exception - Unable To Connect To Remote Server

Mar 6, 2011

My site sends confirmation emails from a purchase. 95% of the time, it works. The other 5% after clicking the 'Confirm' button that runs the payment and should send the email, i get the following exception:

Details:
Exception: Failure sending mail.

Inner Exception: Unable to connect to the remote server

Inner Exception(2): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 72.167.234.197:25

The code to send the email is this:

Dim smtpClientPayPalSuccess As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient()
smtpClientPayPalSuccess.Host = "relay-hosting.secureserver.net"
smtpClientPayPalSuccess.Send(mailMessagePayPalSuccess)

FYI: I have confirmed with the hosting that I don't need any credentials, or a different port number than 25. This is also running over https. why this would be happening only a small percentage of the time?

Visual Studio :: Unable To Debug VB Web Projects On Local Machine / Security Exception Error

Dec 21, 2010

Basically what I am trying to do is have my webpage project folder located directly on my local machine (ex. Local #1). Our database is located on a server (ex. Server #1) . I am building my web applications on my local machine and then trying to debug them in Visual Studio 2008. Only every single time I click to debug my project I get a "Security Exception" error that looks something like the following...

"Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

I'm somewhat leaning towards the fact that I need to connect to the database to pull information from it and I don't have the proper permissions is the reason why this is happening but I've also read that it can be something that deals with improper configuration of my Web.Config file (i.e. I do not have something enabled).

Note #1: A co-worker of mine is having the same problem if he tries to put the project locally and then debug it. He has full administrative access to the DB and everything else.

Evaluate Null Sql Output Paramaters?

Jan 4, 2010

How do you evalute a null sql output paramater. I've tied several ways but can find one that works. I always get an error code of Conversion from type 'DBNull' to type 'String' is not valid.

I've tried both IsDbNull and if the value = nothing - both return the same error.

Code:
If IsDBNull(e.Command.Parameters("@JobCount")) Then
Me.lblInternalJobCount.Text = 0
Else
Me.lblInternalJobCount.Text = e.Command.Parameters("@JobCount").Value
End If
'I have also tried checking for nothing and that doesn't work either

VS 2008 - How To Evaluate A Gridview / Form On Change

Dec 6, 2010

I have a form with 4 independent gridviews and I want to make some other controls, like the form's update button, visible when the gridviews have been corectly completed. I believe I should be doing this Client side so I have written Javascript that successfully evaluates the gridview controls for presence and correct data. Now I need to get the form to run this function, preferably in something like the gridview's onchange event, something that doesn't exist.

Web Forms :: Inline Expression Or Binding Expression In The Server Head Section?

Aug 25, 2010

I write inline expression and binding expression in the server head section:

[Code]....

[Code]....

But both kinds of expression aren't parsed or executed except the ResovleUrl menthod. The html renders like this:

<head><link rel="stylesheet" type="text/css" href="<%= Request.ApplicationPath %>themes/style1.css" /><link rel="stylesheet" type="text/css" href="<%# Request.ApplicationPath %>themes/style2.css" />
<link rel="stylesheet" type="text/css" href="/themes/style3.css" />
<script type="text/javascript" src="/js/jwork.js"></script>
</head>

As I know, the inline expression in the attributes of server control can't be parsed but the binding expression should if we invoke the DataBind method. But the above case breaks the rule.

Web Forms :: Regular Expression Validator / Add Wording To Current Expression:  W+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*?

Feb 16, 2010

I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.

How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*
