Web Form Email Job Problem

I have a web form that pulls data entered by the user, and then sends out an email to the user and an email group based on the category selected by the user. The groups used for the categories are stored within an XML doc. I'm able to parse the XML doc without a problem. I know this because I assigned the email variable to a label on the page, and I can see the result after the form is submitted.

But when I try to apply that same email address variable from that XML parse into the email job within the code file, I receive the following error:
The specified string is not in the form required for an e-mail address.

I've included my code below. If anyone could let me know what steps I'm missing, that would be great. Thanks.

What is in the string strContactsEmail when you create the mail_group MailMessage? If it is a semi-colon delimited list, I think that may be your problem, I think that constructor to MailMessage can take only one email address in a string. If you want more than one create a new MailAddress and use the .Add method to add each of them to the MailMessage.

6/23/2008 9:10:46 PM

Yes, that's exactly it. That variable contains 2 email addresses separated by a semicolon. So could you forward me an example using the code I submitted? I'd like to test it out, but I'm not sure how to proceed. Thanks.

6/23/2008 9:17:10 PM

Try this (this is untested, but I think it should work)


Dim mail_group As New System.Net.Mail.MailMessage()
mail_group.From = New System.Net.Mail.MailAddress(email_form)
mail_group.Subject = "Feeback Form"
mail_group.Body = "<font face='arial' size='2'>The following feedback was submitted to your department:<br /><br/ ><strong>Category: </strong>" & category_form & "<br /><strong>Comments: </strong>" & comments_form & "</font>"
Dim addresses As String() = strContactsEmail.Split(New Char() {";"})

For Each address As String In addresses
    mail_group.To.Add(New MailAddress(address))

After some research, I just found another easier solution. When I changed the semicolon's to comma's, it worked great. But I'm going to also give your solution a try to see how it works. Thanks so much for your help:)

How to Make Web Forms from other Web Forms
In putting together an ASP.NET application for a biz application, we have come to the point where there are three different types of basic forms which have, for the most part, been perfected. Now its is a matter of cloning those forms for various uses and modifying or adding code to suit the particular need. Copy and paste works OK, but there is a lot of changing of certain words, etc. Is there a way in ASP.NET to take these basic forms, turn them into classes or templates, create forms from them, then add or overwrite code? ?

calling a web form from another web form
I would like to know what is the best way to open a web form from another web form. I would like to call it from a button control. Thanks Well, if I've grasped your question right, there are many methods to do that: 1)Response.Redirect > To navigate to another page from code and is equal to clicking a hyperlink. I suggest this as I think it's closer to your question. 2)Server.Transfer > This ends the current web form and begins a new web form. It's usable when you want to pass some variables i.e (Label1.Text) to the next immediate page. It's not safe though and not used to send p...
