Cheers to all the mavens out there on codeproject!

I've banged my head over this one for some time, and I don't understand the reason for this FormatException (log entry) as thrown by Convert.ToInt32 that uses an input value from an ASP .NET 2.0 form *with* validation:

ERROR 16 Jul 2009 09:01:13,970 (Webpage code-behind class name) - Failed conversion of value
System.FormatException: Input string was not in a correct format.
   at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
   at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
   at (name of calling function in ASP.NET code-behind)

The code-behind of the web page is as follows:

try
{
    dataObject.Weight = Convert.ToInt32(txbWeight.Text);
}
catch (Exception e)
{
    log.Error("Failed conversion of value", e);
}

And the web page has the following validation for the txbWeight TextBox control:

<asp:CompareValidator runat="server" ControlToValidate="txbWeight" Type="Integer" 
Operator="GreaterThanEqual" ValueToCompare="0" Text="Positive number only for weight."
Display="Dynamic" />

I don't understand why this exception is thrown, because the validator ensures that an integer is being received from the user (txbWeight also has a RequiredFieldValidator). The odd thing is that dataObject receives the value despite the exception being thrown!? I don't believe I need to call Trim(), and trying this in the past did not fix the issue.

Any ideas?

Always use int.tryparse, not convert.toint32. Do you have text in there, do you need to tell the validator to accept an empty field ?

Thanks for the response Christian. I am indeed using a RequiredFieldValidator for the textbox so it should never recieve an empty input... I can't seem to duplicate this myself in my test environment; it only happens in production so there must be some weird case causing it that I cannot imagine.

Well anyhow, I'll switch over to using Int32.TryParse(...) as you'd suggested; this probably is a better solution and I've had much less frustration on projects by doing the analogous thing with Dictionary<t,t>.TryGet(...).

Hi
I have a treeview on my webpage which is bound to database. On the selected node it should insert a HTML Span Tag with Node value and and Node Text into freetext box using javascript. Like this one

<Span id="NodeValue">Node Text</span>.

As we can not insert HTML into Freetextbox from codebehind therefore I have Used Javascipt funtion for insert HTML.

I have tested javascript function on button click event it is working fine. Remember that I have pass two parameter to javascipt funtion fieldid and field for NodeValue and NodeText respectively.

How I can call javascipt funtion on Node select event in ASP.Net and How I can set values for parameters of this functions.

The HTML Code is

<asp:TreeView ID="TVSectionContentsList" runat="server" Height="200" Width="200" BorderWidth="2">

<SelectedNodeStyle Font-Bold="True" Font-Underline="True" Font-Italic="true" />

</asp:TreeView>

The javascript function is given below

function insertValue(fieldid, field){

FTB_API[ '<%=FreeTextBox1.ClientID%>'].Focus();

FTB_API['<%=FreeTextBox1.ClientID%>'].InsertHtml('<span id=' + fieldid + '>' + field + '</span>');

window.event.returnValue = false;

FTB_API[

'<%=FreeTextBox1.ClientID%>'].Focus();

}

hi,

Is it making Junk in your Company MailBox or in GMail. If you see Gmail, Gmail may check the sender and ignore phishing links provided with the mail.

Check if the IsBodyHtml of the MailMessage object is set to true as well... Smile | :)

And also make proper HTML document always if you set IsBodyHtml to true. Dont put anchor tag inside a plain text email body.

Cannot understand i am attaching my my code 4r ur reference.

try
        {
            string authUser = System.Configuration.ConfigurationSettings.AppSettings["MailServerUserName"].ToString();
            string authPass = System.Configuration.ConfigurationSettings.AppSettings["MailServerPassword"].ToString();
            string domain = System.Configuration.ConfigurationSettings.AppSettings["Domain"].ToString();
            NetworkCredential authenticatedMail;
            if(domain != "")
                authenticatedMail = new NetworkCredential(authUser, authPass,domain);
            else
                authenticatedMail = new NetworkCredential(authUser, authPass);

            string SMTPServer = System.Configuration.ConfigurationSettings.AppSettings["MyMailServer"].ToString();
            SmtpClient client = new SmtpClient();
            client.Host = SMTPServer;
            client.Port = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["MyMailServerPort"]);
            MailAddress from = new MailAddress(fromEmailAddress, fromName);
            MailAddress to = new MailAddress(toAddress, toName);
            MailMessage message = new MailMessage(from, to);
            message.Subject = Subject;
            message.Body = MessageBody;
            message.IsBodyHtml = true;
            message.Priority = MailPriority.High;
            client.UseDefaultCredentials = true;
            client.Credentials = authenticatedMail;
            //client.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
            client.Send(message);
            resultMail = true;
        }

Check how i created body

StringBuilder objMessageBody = new StringBuilder();
                        //objMessageBody.Append("<B> Dear " + txtFirstName.Text + " " + txtLastName.Text);
                        //objMessageBody.Append("</B><br />");
                        objMessageBody.Append("<br />");
                        objMessageBody.Append("Thank you for completing the voter registration for the Industry Personality of the Year.");
                        objMessageBody.Append("<br />");
                        objMessageBody.Append("Please click <a href=" + getConfirmURL(result) + ">here</a> to confirm your vote.");

Is your from address is a real mail address that is declared in exchange?

I am displaying a preview of the Image before uploading it to the server. This works fine with IE6, but not working with newer versions.

The previewing is achieved using an aspx page which has an <asp:image> control. I set the ImageURL property to the "file from the physical location". But in IE7's case, the ImageURL property does not display "file from the physical location".

for instance: <asp:image id ="imgPreview" ImageUrl="file:///D:\image1.jpg">

Kindly provide any help. Thanks in advance.

Regards,
Rijz

Please change the file path from UNC to Virtual. It will then work. Client site should have permission to show the image directly.

Thumbs Up | :thumbsup:

Thanks for your reply Abhishek..

I cannot use a Virtual path here because, this path is obtained from a browse button text field. The user will be selecting file from any physical location on the disc and my program is supposed to preview it. It is working fine with IE6... but not in IE7 Frown | :(

How can I achieve this?

Thanks
Rijesh

I guess it's not working in FF also Smile | :)

This is normal behavior, in IE6 this is security problem. Unless user uploaded something to page, neither JS or ASP should be able to access any information of that file.

All new browsers in FileUpload html element don't anymore show file path, instead only file name.

I think you will have to do it without preview.

ohhh..

Anyway thanks enver for your help...

Hi All,

Hi,

"System.Configuration.ConfigurationManager.AppSettings" I cannot get ConfigurationManager to show up as an option in intelesense. It shows as an error if I try to use it anyway.

Please help me
Thanks

Go to your Solution Explorer and Right click on your Web Project and go to Properties. In the in the Properties Dialog, look for References and Click on add Reference and look for System.Configurations. after that in your application in the usings , add it and everything will be fine.

Then I guess your regex is broken. I suggest you download expresso and/or buy the book 'mastering regular expressions' to learn how they work. You should also break down your regex, removing a part at a time until you work out which bit is broken, and then work out why, or ask a more specific question here that shows you've tried to solve your own problem

Its means user does not have the sufficient permission to access the site.

Just give Anonymous access and Give the folder read access to every body.
