I'm using ASP classic and CDO to send email with CreateMHTMLBody method. I have couple of images in my email which some of them are static and would not change but some of them will change based on email content. Some of the mail softwares like iCloud showing the pictures as attachment even though I have them all with full path url address. I've used AddRelatedBodyPart but right now they show the images in the place that thy have to be but still they show the images in attachment as well. I want the picture just show in body of email not in attachment. Does any one know how to fix this? Here is the example of my code:
Set myMail=CreateObject("CDO.Message")
myMail.Subject= "Subject of Email"
myMail.From= "from#site.com"
myMail.To= "to#site.com"
myMail.CreateMHTMLBody "http://www.mysite.com/email.html"
strImagePath = Server.MapPath("\") & "\images\mypic1.jpg"
myMail.AddRelatedBodyPart strImagePath, "my_pic_1", 0
strImagePath = Server.MapPath("\") & "\images\mypic2.jpg"
myMail.AddRelatedBodyPart strImagePath, "my_pic_2", 0
myMail.Send
set myMail=nothing
Thanks in advance for your time and help.
In order to have images in emails, you have to use inline IMG tags in the body of the message with the fully-qualified path to the image (http://...). DO NOT treat them as attachments.
The CreateMHTMLBody is not what you need. This method will create a multipart message fetching the URL and post processing the HTML returned. It fetches the resource for every img src it finds, encodes the returned resource as a body part and updates the HTML img src to point at the body part.
Also CreateMHTMLBody is not a good thing to use in ASP code since it uses the WinINET Http stack to fetch resources, WinINET should not be used from ASP code.
What you really need is to use something like WinHTTP to fetch the HTML resource and then assign that to the Message's HTMLBody property.
I know this question is old but maybe you (or someone else) is still looking for the answer:
myMail.Configuration.Fields("urn:schemas:httpmail:content-disposition-type")="inline"
myMail.Configuration.Fields.Update
This should cause most mail clients to not render images as attachments.
true;
strImagePath = Server.MapPath("\") & "\images\mypic1.jpg"
response.write strImagePath ' try
myMail.AddRelatedBodyPart strImagePath, "mypic1.jpg", 0

I am using asp.net 3.5 and C#.
I have a image which I want user can download.
Like, there would be a download button or link. When user click on this link he will be prompted with a pop up to save that image to his desktop.
I have tried with
<a href ="path" > </a>
but it is opening the image in other page, I want user to be prompted to either save or view the image,
please help
Thanks in advance
You need to write an IHttpHandler that serves the image along with a Content-Disposition header.
For example:
Response.AppendHeader("Content-Disposition", "attachment; filename=\"MyImage.png\"");
Response.TransmitFile(path);
You would probably pass the image name on the query-string.
If so, make sure it doesn't contain / or \, or attackers will be able to read arbitrary files.
You need to have another page or, better yet, an HttpHandler, that takes the image path as part of the query string or as a post parameter that will send the response with Content-Disposition set to attachment. Setting the content disposition this way will cause the browser to display the file download dialog. A slightly easier way, though it depends on the user doing something extra is simply to have the link open the image in a new page and let the user right-click on it and do a "Save As".
Download
or
<a href="/path/to/image" target="_blank">
Load Image in New Window then Use Save As</a>
I have written a ASP.NET program for a customer, I want to add a message similar to "Preview version, ABD Consulting" on the master.master page, I had thought to use Response.write but it messes up the look of the page as it seems to move page elemets. If I use a label the customer can remove it from the Master.master file, any suggestions? The customer is in a different country so I want to ensure I'm paid.
Many thanks
Serve it on your own server. If it's a preview, they shouldn't have access to the code anyway.
There is nothing you can do unless you host it or control the web server it runs on. Nothing you do in code will matter if they are smart enough. They can write their on HTTP Handlers and replace anything they want.
If you programmatically write out the label during the OnPrerender or Render of the page then the client will not be able to remove it. If you then randomize the ID given to the element, they will find it incredibly hard to apply any javascript functions or CSS styles to it, especially if you directly add the styles to it.
Something like this (pseudo code):
HtmlGenericControl label = new HtmlGenericControl("div");
label.ID = Guid.NewGuid().ToString();
label.InnerText = "My copyright or ownership text";
label.Style.Add(HtmlTextWriterStyle.Height, "50px");
label.Style.Add(HtmlTextWriterStyle.Width, "100px");
if you then absolutely position it, it should always show up. Note that it isn't totally untouchable and fool proof, but you want to just make it hard enough that the client doesn't try to remove it.
Obfuscate it in a dll and use the Current Context to write a pretty div like the one that StackOverflow.com uses on top.
I'm with George and Rick - don't let them have the source and serve it up from a server you control. In addition, I'd created a background image that says "Demo". This will remind that they need to pay up.
i have an action that return a file content. i added:
Response.AddHeader("Content-Disposition", "attactment; filename:\"" + survey.File + "\"");
so that the image would be opened in another tab/page, gets opened in the current tab/page.
whats wrong with the header?
The content-disposition header instructs the user agent how it should present the data, and it is usually used when serving up binary data (as opposed to plain text). When set to "attachment", the display of the content is contingent upon further action of the user. In other words, the user should receive a prompt and must decide what to do with the content (usually given an "Open" or "Save" option).
You can not programmatically force a hyperlink to open up in a new tab. Even if you could, you should not. This behavior should be controlled by the user agent. As a user, when I want to open something in a new tab, I use the mouse-wheel-click because that is how my browser is configured.
You cannot control browser's tab behaviour by using HTTP headers - there is nothing in your code that affects this.
What might help you is changing HTML code that points to your download - if you are using tag you can set its target attribute to _tab or _blank and it will work in many browsers.
My controller, in a nutshell is this:
chart1.SeriesCollection.Add(SC);
using (MemoryStream ms = chart1.GetChartStream())
{
return File(ms.ToArray(), "image/png");
}
My view is this:
$('#targetDiv').load("Home/GetImage");
And I'm getting garbled characters when rendered. Any ideas?
thanks,
rodchar
You need to use an img tag:
<img src="Home/GetImage" alt="" />
When you write $('#targetDiv').load("Home/GetImage"); you are basically saying: send a GET requets to Home/GetImage using Ajax and if the request succeeds update the contents of #targetDiv with the result. As your controller action sends binary data, this binary data will be injected into the div.
You should set the content type of your response to accommodate the fact you're sending back an image. If you don't your binary stream will be interpreted as text, hence the garbled stuff you get.
There's a related question here: Can an ASP.NET MVC controller return an Image?
Try adding this to your code, before you read the file and send it back
this.Response.Clear();
this.Response.ContentType = "image/png";
on the markup side instead of putting the content into a div you need to put it into an image tag.
I've got an ASP.NET ashx class that retrieves data from a database, creates a PDF file using iTextSharp, and streams the PDF to the browser. The browser (IE and Firefox at least) is launching Acrobat Reader as a separate window to open the file. I'd like for it to display inline within the browser.
Is that something I can completely control from the server side? I'm already setting the Content-Type header to application/pdf, and I've tried setting Content-Disposition and Content-Length. Nothing so far has worked.
Is there another header I'm missing? Is there something in the PDF itself that tells the browser how to display it? Any other ideas?
Setting the content-disposition and content-type headers should do it, but you might also need to call Response.ClearHeaders() to clear other headers that have been set.
Also, try using Fiddler to see the actual headers and content from the response and compare them to those from a site that works like you want.
If you are using an ashx (web handler) try this:-
context.Response.AddHeader("content-disposition", "inline; filename=Something.pdf")
OK, turns out it was a stupid question, but I'm glad I asked it because I had never heard of Fiddler (which led me to the answer, which is why I'm accepting tspauld's answer). The PDF is generated by a web service that serves the file to a couple of different front-end sites. I was setting the content disposition to inline in the service, but that didn't matter, because the browser never got that header; it got the header from the front-end site (which was attachment). I changed it in the front-end site and that fixed it.
So the answer is that you have to have Content-Type=application/pdf and Content-Disposition=inline; filename=Something.pdf, as others have said.
Try generating them into your page using html OBJECT.
<OBJECT WIDTH=640 HEIGHT=480>
<PARAM NAME="SRC" VALUE="<%=filePath%>">
<EMBED SRC=<%=filename.pdf%> WIDTH=1000 HEIGHT=680>
<NOEMBED> PDF should have displayed here!</NOEMBED>
</EMBED>
</OBJECT>
If you need to stream the response with an ashx instead of being able to return an aspx, I think you may be out of luck.
Otherwise, I believe the settings to show in browser or not, is completely client driven and out of your hands.
So, I have a sample in one of my works that is what you need:
<cc1:ShowPdf ID="ShowPdf1" runat="server" BorderStyle="None" BorderWidth="0px"
Height="750px" Style="z-index: 103; "
Width="750px"/>
and in server side :
ShowPdf1.FilePath = String.Format("~/Handlers/Pdf.ashx?id={0}#view=FitH&page=1&pagemode=none&navpanes=1", myPublicationId);
I place here also some code from my PDF Handler :
Response.ContentType = "application/pdf";
byte[] bytes = YourBinaryContent;
using (BinaryWriter writer = new BinaryWriter(context.Response.OutputStream))
{
writer.Write(bytes, 0, bytes.Length);
}
Anyway If my post doesn't seem clear to you, have a look at this sample How to Display PDF documents with ASP.NET
I think this header will do what you want
Content-type: application/pdf
Since you say that is not working, then I suspect it is a configuration setting on the client side.
Check your installed version of Adobe Acrobat. There is a setting in preferences for "Internet" and a checkbox that says "Display PDF in Browser".

Here is an article on using the embed tag to do it:http://blogs.adobe.com/pdfdevjunkie/2007/08/using_the_html_embed_tag_to_di.html
If you have the budget, my company sells a set of products that includes an AJAX based image viewer that will let you view the PDF pages in line without Acrobat at all. In its simplest form, it is just a viewer, but you can layer in interactivity as you need.
