In my application when i debug in catch block this error is showing,given below
"[System.Threading.ThreadAbortException] = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}"
The code was executing fine but now an exception is generated: "exc = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}"

i'm having a serious problem when i' trying to use "HttpContext.Current".
What i' trying to do is to get a querystring value by:
"HttpContext.Current.Request.QueryString["..."]" (in my page base class)
But i got this error:
"Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack"
What could be causing this problem?
[code]....
I am using asp.net 2.0 with c#.
" myReportDocument.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, Response, false, rptName);"
As soon as compiler execute this statement i get error
" [System.Threading.ThreadAbortException] = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.} "
What will be the possible reasons for the error.
Although it throws execption but it will allow to convert report when i deployed my site using http but when i deployed my site using https then it will shows error .

I want to export the data to pdf in which table has 150 columns.Â
When i save the file in directory , the file is opening. whereas when open it directly some box type is displaying.Â
And also am getting exception in Response.End() method which is given below
"Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack."Â
I have a class...see code below
[Code]....
and I am calling the class using this syntax....
DataExporter.ExportToXLS(gvtemp,
string.Format("{0}.xls",
DateTime.Now.ToString("ddhhmmss")));
however, i am getting the exception, unable to evaluate expression because the code is optimized and usually, you fix it by adding a false to your response.redirect.
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
View 1 RepliesI 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.
I am preparing string expression to use it to insert statement like
str="insert into franchise (xx,yyy,xxxxx) values (" + rblxx.SelectedIndex + 1 .............
when I do so it simply concats the thing like value of rblxx.SelectedIndex "0" and 1 makes 01 and not 1.suggest some function and trick to add the numeric values not concat. I tried using System.Convert.ToInt32 but not worked for me.

When I added Regular Expression validator on FileUpload Control, Page.IsValid returns false & Data is not Saved. I had used Regular Expression Validator like this:
asp:RegularExpressionValidator
ID="REVFileType"
runat="server"
ErrorMessage="*Invalid File(.bmp)"
ControlToValidate="FileUpload1"
Font-Bold="True"
SetFocusOnError="True"
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.jpg|.JPG|.gif)$"></asp:RegularExpressionValidator>.
I had used it to check if uploaded file is of extension .jpg|.JPG|.gif
I get a error on this line

I am getting an Identifier expected error under the closing tag of this expression but the code seems to be ok.

View 15 RepliesI have written some vb code that inserts whatever has been written on my page into an Access database. Only problem is VWD throws up an error saying that the syntax of my SQL statement is wrong. I am 95% sure that this statement is correct because when I saw the statement in Text Visualizer and tried that statement in MYSQL the data went in perfectly.
I have pasted the code below:
strSQL = "INSERT INTO User (UserID, FirstName, LastName, Password) VALUES "
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.
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+)*

I'm new to c# and I seem to be having a problem with an error message. If my textbox is left empty my code will throw a format exception and display the message in a label. If I then add a number to the textbox it runs correctly but the error message remains.

I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
