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.}"
[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 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

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.
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.
how can i optimized this code? i dont like to have case statement, is there a way i can improve this code?
protected void ddlFilterResultBy_SelectedIndexChanged(object sender, EventArgs e)
{tring selVal = ddlFilterResultBy.SelectedValue.ToString().ToLower();
itch (selVal)
{
case "date":
[code]...
is there a way i can optimized this code and make this extensions on web.config settings so i can read from there and in future if i need to add or remove i should be able to do easily?

I'm getting the above error message in my C# code on my asp backend pages.
here is the line:

The error message occurs on every line that uses this ?: expression format, but MSDN says it's legit.
how to code the following regular expression
ABC[1 digit Number b/w 1-4]1A[7 digit number 0-9]-5[5 digit character]

At my current place of employment, a university, we are going to take a stab at making a mobile browser-oriented section of our web site. I was wondering if anyone could direct me to some good resources that they know of for such a thing. Primarily, names of books would be nice, but any kind of resource at this point would be extremely helpful. We are approaching this as more of an HTML project at the moment, so the resources don't need to be Asp.Net based, but such things would be great too.
View 4 RepliesI have a webservice I need to call via a link. The webservice returns a pdf document and takes a document Id as a input parameter.Under normal circumstances I could have the link call some code in the code behind which in turn calls the webservice.
However the difficult part about it is I can't add code to the code behind. The reason is it is for some CMS users who want to know what links to add to the page which will download the pdfs. I can only add the link to the aspx page.
I am trying to match an email, however when put the same expression in the code behind, vs the aspx, I seem to be getting different matches for email address. The aspx regex validator seems to be working correctly, however I need to validate for my webservice as well.
Regex regExEmail = new Regex(@"w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*");
if (!regExEmail.IsMatch(contact.emailAddress))
{
//do something
}
