Im tying to write an exception message using javascript in code behind, using
catch (Exception ex)
{
string err = ex.Message;
string script = "alert('" + err + "');";
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "Msg", script, true);
}
But sometimes the message doesnt get dislayed and the whole application freezes, i have noticed that its caused by the content of ex.Message
eg "Unable to cast object of type 'System.DBNull' to type 'System.String'." - gives a problem. The easiest thing to do is to replace the ' signs and it works fine, but this is applies to this error message only, is there a generic solution for this problem.
Thank you.

response.write("<script>'alert(' + ex.Message + ');'</script>");
this wont work if you have ' in the exception message
think we have to write a method which replaces all special characters (ex: ' with \' and " with \")

You can try
Response.write("alert('" + err + "');");
You can also try placing a label on the page then assign text to label as
message.Text = "");

You haven't got the concept of this site. Read this[^] especially point2 and point9.

You'll probably want to create an LDAP query against your active directory. There are a number of examples online - just bear in mind that your asp.net process will need to have sufficient authorisation to make these queries.

Hi coders,
I want to display one HTML file contents in my aspx page. I am using for that. what I have written is:
aspx page:
<iframe frameborder="no" id="htmlAboutUs" style="width:100%; height:500px;" runat="server" scrolling="no">
cs file:
htmlAboutUs.Attributes["src"] = Server.MapPath(FolderName + "/styles/About-Us.html");
where FolderName is comming from session.
Its not working but. its showing blank page in result(not even "Page Not Found").
Then I tried another one:
FileStream fs = new FileStream(Server.MapPath(FolderName
+ "/styles/About-Us.html"), FileMode.Open);
byte[] data = new byte[fs.Length];
fs.Read(data, 0, (int)fs.Length);
fs.Close();
string dataString = Encoding.UTF8.GetString(data);
htmlAboutUs.InnerText = dataString;
It is also not working. I have checked that its bringing correct data in dataString but not displaying. mean my file contents are properly read but its not assigned to iframe. Please give some gidence.
Thanks for any help.

That is because you are using MapPath to return the Physical path as seen internally on the server. The browser does not have access to that. You must use a URL (http://domain/folder/styles/About-Us.html)

I am using localhost anyways. and i think, on web server also, MapPath should work properly.
Thanks.

No. MapPath will give the physical path to the file. That physical path is not accessible from browser. So you need to render path like www.yourdomain.com/folder/filename.html

It should do. You may have to change some settings in the web.config to match your new environment. Database connection strings for example, you'll want to turn debugging off, etc.

There may be IIS settings that you need to change that require admin rights, if it isn't already set up for you.

Publish the website, copy the PrecompiledWeb folder that was created in the publish operation to the server and put it in the correct place.

Heard about viewstate? ASP.NET will not maintain viewstate for controls created on page_load. Read about ASP.NET page life cycle.

Reposting the same question so soon only irritates people.

Hi I am new in programming. Currently I involved in developing a website for a company. I use microsoft visual studio 2008 to create my website. I wish to add modules to ease my job to track the bug and store the exception in a text pad. As I know for window based application and web application are able to create a module and use in page. Is it possible to do in a website?
i add a class in my App_Code, when i want to call the method in the class, it show the blue line under my text. When i mouse over my text, it show "Reference to a non-shared member requires an object reference."
Need help

Hi,
i'm just guessing but are you trying to access your code without an instance of the class? If you want to do so, you have to options. Create an instance using the new-keyword or declare all methods in your class static so that you don't need an instance.
Please be so kind to post your code (the underlined one, and the one you are trying to access). This will help us to solve your problem.
Regards
Sebastian
