I want to be able to paste clipboard contents with functional hyperlinks to my Winform controls. In order for this to work I tried to check if the Clipboard contains HTML and no RTF and then I could parse the HTML content accordingly. Unfortunately the Internet Explorer generates RTF and HTML in the clipboard content and that way I can't really tell that the content is comming from a browser. Microsoft word for example does the same thing and the only way I found so far to differenciate office products from IE is to check for the namespace xmlns:o"urn:schemas-microsoft-com:office:office" in the HTML content of the clipboard. I can't simply use HTML in all cases, because I prefer the RTF or simply the unicode content from other sources than browsers.
Is there a way to determine that the clipboard content comes from a specific application? In my case from IE? So far I only used Clipboard.Contains(TextDataFormat.HTML) and Clipboard.GetDataObject().GetFormats() but I can't find anything else.
You can use P/Invoke class to get the calling applications window title using http://pinvoke.net/default.aspx/user32/GetWindowText.html. For IE the title is the name of the page and suffixed with - Microsoft Internet Explorer, default title for this IE.
This is sample code how to use GetWindowsText
C# how to use WM_GETTEXT / GetWindowText API

I have a webbrowser control in my application that is used to display pdf files that have been created in iTextSharp and are stored locally on the hard drive.
I would like to be able to navigate the file (next, previous, first, last, toc) from my application rather than using the inbuilt nav of the reader in the browser.
I have seen that you can navigate to specific pages by using
Browser.Navigate("filename.pdf#page=?);
This works the first time but when trying to navigate to a different page, it makes the browser disappear completely with no errors. However, I can reload the file without problem if I don't have the #page=? suffix on the file url though. Any ideas on this?
Alternatively, is there anyway in iTextSharp of adding something to the file to allow for it to be navigated from an external command?
All the official parameters that can be used to navigate through a PDF using parameters in the query string after the ? character are listed in a document published by Adobe: Parameters for Opening PDF Files
You already mentioned the page parameter. Another option could be using named destinations: nameddest=destination. In this case, you need to add the anchor with name destination to the file using iTextSharp.
Note that not all viewers implement these parameters. Adobe supports them in Adobe Reader and in the Adobe Reader plug-in, but there is no guarantee that they will work in pdf.js (Firefox), Pdfium (Google Chrome),... If your browser disappears when using an open parameter, you may have hit a bug in the browser or the viewer plug-in that causes the browser to crash. iTextSharp nor iText can crash a browser ;-)
There are no other ways you can navigate a PDF from an external application. The only thing you can do, is to add JavaScript to the PDF so that it always opens at the same page. This is done using an open action. I don't think this solves your problem as it would mean that you have to change the PDF file every time you want it to open at a different page.
I am using the Aspose PDF tools and have successfully got it to print the pdf which is great, but ideally I want to be able to add a wpf control to display this as well.
I would have assumed that the PdfViewer class would have something, but I can't tell.
So far I have needed to use a different control MoonPdfPanel which is annoying as I would have preferred 1 tool to do both jobs.
Does anyone know of a control I can use to hook into the aspose?
Thanks
We have developed an HTML5 PDF Editor application using Aspose.Pdf for .NET API which you can use in your application as a PDF Viewer as well. You can get the details and complete source code here. You can use the source code to edit the viewer as per your requirement.
P.S. I am working as social media developer at Aspose.
Well, if you are interesting in viewing the PDF file, you may convert the file to HTML and display it using an IFrame in your application. I have developed a sample application which performs different operations including viewing a PDF file in IFrame. Download it and try it at your end. Another option is that you can convert the PDF file to images and display in Imageviewer in your application (Code is available in the above application).

We have a Winforms application which supports dragging and dropping chunks of HTML into Outlook (HTML) mail messages.
Chunks of text are fine.
But how do we proceed with images? Let's assume we don't want to host the images online but instead we want to send them with the email message. Assume also that we do want to see the image inline, not as an attachment (where the recipient's email client supports that, of course).
If you look at the HTML source of an Outlook message there are "cid" tags for images (which point to the image as an attachment I guess), but how do we go about generating a cid/contentid?
If a manual step in the process is an option, you can do it like this:
create the HTML automatically or manually as a saved HTML file, with <img> tags that link to locally-saved image files
attach the HTML to an Outlook email using the 'Insert as text' option tucked away under the down-arrow on the "Insert" button when selecting the HTML file as an attachment.
This populates the HTML email with the HTML from the file and embeds all images. I believe this tool uses Base64 encoding to embed the images as described in Sam's email.
Depending on the workflow, this method might be easier than converting images to Base64 yourself.
Note that this method only works in Outlook for Windows, not Outlook for Mac.
You can embed images in a html email using a base64 encoder. Its quite complicated but you basically encode the image as a text string in the email which is then interpreted.
This does not work in all email clients though.
Take a look at this and see if its what your looking for:
http://www.campaignmonitor.com/blog/post/1761/embedding-images-in-email/
EDIT
The updated campaign monitor post on the clients which work with base64 images.
For the last part of your question, "generating a cid/contentid" I know the only way is useing outlook itself (or Word as a text editor of Outlook) to get that.
I had faced this problem when I needed to insert our company logo beside my signature text on the email.
So, open Microsoft Outlook (office 2016 im ny case) go to File > Options > Mail > Compose Messages > Signatures button
or inside the Outlook New Message windows, go Insert > Picture
If you are using html to make your whole email, you can search google for the same image, and put this in there:
<img src="http://www.google.com/intl/en_ALL/images/logos/images_logo_lg.gif" alt="picture1" />
You can also, use photobucket to host images (if you have to). Basically, you HAVE to have a source for the image.
I'm trying to send a PDF file from a WCF to silverlight client. PDF is generated by DevExpress XtraReports (in method XtraReport CreateReport(string reportTypeName, RootGenericReportParameterContainer reportInformation)).
Acually PDF is saved somewhere on clients computer after choosing save path in file save dialog - DevExpress takes care of everything - but I don't have a clue how to open the PDF in new tab in browser.
And here is another problem. Silverlight 4 has no access to local file system right? So information about local PDF location is useless. Maybe it would be better to save the PDF in WCF and send a link to it to the client - but how?
I would first question why you need to send the file to the Silverlight client. Get rid of that requirement and the solution becomes much simpler. Silverlight can provide a link that opens a new browser tab. That link would be handled by the web domain, processing it as an HttpHandler, generating the PDF file for the browser. Your PDF url doesn't have to reference a physical file, you can still generate it on request, handle querystring values, etc... Lots of different ways to do this.
Seems that the question isn't really about DevExpress or Silverlight - you're just looking to open a [document of some kind] in a new tab. Each browser natively handles things differently, and users can change tab handling to whatever they want. And (as you mentioned) once the user has downloaded the file, you no longer control it.
Your best bet (and the way I do it) is probably to have a link pointing to a handler/file using "target='_blank' " in the anchor tag on the webpage. From the server side, you would want to set the "Content-Disposition" header to "Inline" to indicate to the browser that the document should be displayed in place instead of downloaded ("Attachment").
I'm planning to use thw WebBrowser component to display html that is created on the fly. The perfect choice for this is NavigateToString or NavigateToStream methods. There's only one single problem - I need to load images / css styles / js files too. How do I accomplish this while using string/stream?
As an option I'm also considering writing/finding simple http server and running it on some port, but that's an additional work and requirements(open ports) so I'd like to avoid that if it's possible.
You can cast WebBrowser.Document to IPersistMoniker and load a moniker that implements GetDisplayName. Check http://csexwb2.googlecode.com/svn/trunk/cEXWB.cs for example code.
Faced with this same problem I created my own solution. You can see it here:
