The problem
Using itextSharp to convert an html file to pdf and emailing it, I am unable to successfully parse an html file on the web server backend even when doing "absolute" or "relative" image referencing itextSharp fails and says "unable to find file c:\my_image.jpg" this is crazy didn’t specify c:\my_image.jpg as a path !!!
The madness of all this is it works well on my local file system, when the html file is located on asp.net using an IIS webserver i get the above described error.
Here is my code.
<html xmlns="http://www.w3.org/1999/xhtml"><br />
<head><br />
<title></title><br />
</head><br />
<body><br />
<table width="100%" border="0" cellpadding="1" cellspacing="5" style="font-size:10pt font-family:Arial, Tahoma"><br />
<tr><br />
<td colspan="2" align="right"><br />
<img src="logo.gif" /><br />
</td><br />
</tr><br />
</table><br />
</body><br />
</html><br />
<br />
<br />
asp.net code behind <br />
<br />
private void SendEmail(string attachmentName, string pdfDocumentHtml, <br />
string mailSubject, string mailBody, MailAddress fromEmailAddress, <br />
List<mailaddress> toMailAddressCollection)<br />
{<br />
Document doc = null;<br />
XmlTextReader reader = null;<br />
MemoryStream ms = null;<br />
MemoryStream msPdf = null;<br />
MemoryStream msHtml = null;<br />
try<br />
{<br />
<br />
doc = new Document(PageSize.A4, 10, 10, 10, 10);<br />
<br />
msPdf = new MemoryStream();<br />
PdfWriter.GetInstance(doc, msPdf); <br />
msHtml = new MemoryStream(new ASCIIEncoding().GetBytes(pdfDocumentHtml)); <br />
<br />
reader = new XmlTextReader(msHtml);<br />
reader.WhitespaceHandling = WhitespaceHandling.None;<br />
HtmlParser.Parse(doc, reader);<br />
ms = new MemoryStream(msPdf.ToArray());<br />
<br />
<br />
var attachment = new Attachment(ms, new ContentType("application/pdf"));<br />
attachment.Name = attachmentName;<br />
attachment.NameEncoding = Encoding.UTF8;<br />
MailMessage email = new MailMessage();<br />
email.From = fromEmailAddress;<br />
<br />
foreach (MailAddress address in toMailAddressCollection)<br />
{<br />
email.To.Add(address);<br />
}<br />
<br />
email.Attachments.Add(attachment); <br />
email.Subject = mailSubject;<br />
email.Body = mailBody;<br />
email.IsBodyHtml = true;<br />
SmtpClient client = new SmtpClient();<br />
client.Send(email);<br />
}<br />
finally<br />
{<br />
<br />
if (reader != null)<br />
reader.Close();<br />
if (ms != null)<br />
ms.Close();<br />
if (msPdf != null)<br />
msPdf.Close();<br />
if (msHtml != null)<br />
msHtml.Close();<br />
}<br />
}<br />
</mailaddress>
Thanks in advance

What does it code do? Can give me an example
String str;
str.TrimEnd(new char[0])
Thanks.
|
|
|
|
|
it will remove the \0 character from the string.
|
|
|
|
|
what do 'new' and 'char[0]' means?
Thanks
|
|
|
|
|
new is a keyword used to instantiate an instance of something
char[0] is an array of chars with zero elements.
This basic stuff is usually covered in the first few chapters of any beginner book on programming.

Really, if you need to know this I suggest you start a basic programming course.

It was really a good one. And the citation suited very well to what Ashfield noticed

Hello Everybody,
All I am trying to do is to call the wcf service which is hosted using windows service in another machine. The server certificate I have is generated using the makecert following the article http://www.codeplex.com/WCFSecurity/Wiki/View.aspx?title=How%20To%20-%20Create%20and%20Install%20Temporary%20Certificates%20in%20WCF%20for%20Message%20Security%20During%20Development&referringTitle=How%20To%20-%20Use%20Certificate%20Authentication%20and%20Message%20Security%20in%20WCF%20calling%20from%20Windows%20Forms
I installed this certificate in trusted publishers rather than in Personal. I am able to call the service in the same(where the service is hosted) machine. When I copy the client to another machine and try calling this service, it returns this exception.
{"The remote server returned an unexpected response: (407) Proxy Authentication Required."}
this is how i referenced the webservice:
ServiceReference1.ServiceClient GetTablesSVC = new ServiceClient();
this is where it throws the exception
ds = GetTablesSVC.GetTablesToBeUpdated();
Any quick help is greatly appreciated

Yes, its considered rude.

Then pay for support rather than getting it free from volunteers.

Yes it does. Let me explain.
People here only read the forums they know stuff about. If you post in multiple forums, 2 different people may answer your question. This means one of those people has wasted their time giving you an answer, because someone else had already answered it but they didn't realise. Or if they do notice you've posted in multiple places, they have to waste their time like Pete has linking your posts together.
People here answer questions for free, so you should do your utmost not to waste their time. It is polite to post your question in just 1 forum.
The fact that your desperate and your problem is urgent doesn't make any difference. If you need an answer urgently you should phone MS tech support and pay for it. If you want an answer freely, bide your time and let someone answer it at their own pace when it's convenient for them.

Yes, because it irritates people.

Then, you have one option, start looking for a different line of work.

Hi Guys,
I've got an windows forms application developed with c#.
My admin just rang me up, as he installed the application testwise on one of our client pc's, that he explicitly has to give the user the permission to write into the application directory.
the application is installed under c:\progam files\applicationDirectory. The application is using a xml-file to read and save application data.
my question is - what can I do to set the permissions correctly on pc's where the user is not neccessarily an administrator. (and I would like to leave the data xml within the applications directory, if possible...)
any suggestions are very welcome
thanks
