I am looking for a free or commercial programme which will let me open up TIFF files in .NET.
Ideally it would open up in a new window, with 2 restrictions 1) That user isnt able to save the file 2) That there is no print button available.
I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too.
Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive.
The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats.
For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window.
The problem:
As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem.

Is this problem easier than I think or is it as nasty as I am expecting?
I may be forced into using a tiff image on a webpage.
Do most modern browsers handle tiffs. Are there any gotchas?
When I upload small sized tiff file(approx. 800KB) in my website folder on local system through fileupload control in asp.net. It uploads the file successfully. But when I upload 5MB or more in size tiff file. It can't upload file and display the following message.Internet Explorer cannot display the webpage.Here is my code:
if (FileUpload1.HasFile)
{
string filename = FileUpload1.PostedFile.FileName.ToString();
[code]...
[Code]....
That's my C# code but i the "ReportViewer1.LocalReport.Render("PDF", null, out mimeType, out encoding, out filenameExtension, out streamids, out warnings);" came in error everytime i try to generate the report. Can you show me the way so i can view the pdf from the browser or save the pdf from the browser?
How to display tiff, png images in ASP.NET or windows application in IE browser.
View 1 RepliesI've got a ASP.NET site that's located on a local server (MY_SERVER). And one of the things it does is pull up tiff files which are located on another server (ANOTHER_SERVER). The location of each of these files is stored in SQL. I pull up each of these images and am supposed to display them. The problem is:
the files are not named with a tiff extension (does it matter?) they aren't displaying at all.
I am using an Image control to display these images, and I'm not sure if it matters that the extension is not set (does the image control know the difference between an jpg and a tiff without the extension?)
I am guessing the images aren't displaying because they are not on the same server MY_SERVER that the images are located (ANOTHER_SERVER).
edit: actually displaying the tiff files were amazingly simple:
protected void Page_Load(object sender, EventArgs e)
Response.ContentType = "image/png";
new Bitmap(Request.QueryString["ImagePath"]).Save(Response.OutputStream, ImageFormat.Gif);
}
but because the images are located on ANOTHER_SERVER I still can't access them. I may just do a hack where I copy them to a local directory on MY_SERVER but there's gotta be a simple way to fix this. Anyone?
I am using alternatiff plugin to view tiff in web browser. But my main aim is to disable saving the copy of tiff file in temp internet files folder. and the second is to view some specific 2-3 pages from the entire tiff files. (SECURITY IS THE MAJOR CONCERN) or is there anything alternative which can help me out from thes.
I am working on this from last two days but couldnt get to the solution for this.
My website provides a facility to upload images, using the ASP.NET FileUpload control. We accept both jpeg and tiff formats but I have just decided that all tiffs should be converted to jpegs at the time of upload. If possible, I want to avoid saving the original tiff to disk. I would any sample coding for achieving this conversion prior to saving (ideally in VB.NET, though I could always run C# code through a converter).

when i convert tiff file to pdf in debug mode it converted successfully but when i host it on localhost it didn't convert and throw an exception:
Cann't make pdf files. Try again.System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {71DBCBF1-587B-42E4-9B30-74B80F4AA70F} failed.
I need to send an image (as a downloadable file) from an ASP web page. It is working correctly in every browser except for IE (all versions).
Here is the server side code:
bool export = Request.QueryString["Export"] != null;
if (export)
{
byte[] allBytes = File.ReadAllBytes(@"C:MyImage.tif");
Response.ContentType = "image/tiff";
Response.AddHeader("content-disposition", "attachment; filename="MyImage.tif"");
Response.OutputStream.Write(allBytes, 0, allBytes.Length);
Response.OutputStream.Flush();
Response.End();
return;
}
And here is the JavaScript:
$('#ExportFrame').attr('src', 'Default.aspx?Export=true'); // ExportFrame is an iframe
In IE, I keep getting an error saying "Internet Explorer cannot download Default.aspx from localhost". I thought it might be an issue with loading it in an iframe element, but redirecting to the URL is not working either. The really odd thing is that going to the URL (/Default.aspx?Export=true) does not work the first time, but works every time after that. Again, this works in every browser I've tried except IE.
Update:
The aspx page has the following code to keep the page from getting cached:
// Never cache this page
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
Response.Expires = -1;
Removing the first 2 lines and leaving only Response.Expires = -1 resolved the issue.
I have a asp.net app that writes a pdf to file. Then, later that file is opened into a window (standard acrobat reader) for viewing. No problems there.The weird part.The entire document loads as it should, but the Reader initially shows the last page in the document on the screen. The user must then scroll up to the first page. It doesn't happen all the time (about 50%) and occurs across several test computers. Is there a switch in the code I'm suppose to use in creating the file or displaying the file to tell the reader to "start displaying the document on the first page?"
[code]...
I'm looking for a web component which may be free or paid anything which can be used to view the doc, pdf and image file online without having any of those software i.e. MS Word, Acrobat Reader installed. Can u please suggest me such components. I want all of the above formats to be supported. This would be used in viewing the attachments uploaded by user.

Never worked with Sharepoint, but need to add a WebPart to display a PDF document. How does this work? There is currently some code to add a ReportViewer (SSRS) WebPart, but I need to replace it to display a PDF file (from disk). The PDF file is from a local/network path that is not served publicly. I need to get the PDF content streamed in a web part, setting the content-type along the way. If it helps any, my thoughts are to respond on a different URL (page in the same site), that simply takes some token (get params?) and streams a byte[] and sets the content-type as application/pdf - I could well be completely off the mark. You will need to be quite specific with steps and code/sample/links in the answer.
View 2 RepliesI had some problems with Visual Web Developer Express 2008 recently, so I decided to reinstall it.Since then I have not been able to get ReportViewer to work again.When I try top open an rdlc file in the VWD environment, it opens in source view not design view. So I can not edit it, the way I normally would.I cannot add a new report. However the reports I have already created still work when I run the application.have tried unistalling and reinstalling everything, SQL Server Express 2008 (SP1), Visual Web Developer 2008 and Microsoft Reprt Viewer Redistributable 2008.I can not seem to get the environment back to how it was before.

View 1 RepliesI have a ssrs report which in run time having a prob in scroll bar.
In runtime both the vertical and horizontal scroll bar is appearing but it is not getting scrolled even with scroll bars.
<td><input type="text" name="textfield" class="cntct_frm_on1"/></td>
This I have to change to text box and I have to get the complete design there while using the asp .net
As we all know, the report viewer control has an export to pdf option. But whenever the report is exported to pdf,the format gets disturbed. If my report has about 3 colums like empID,name,phone etc.... then empid and name come in 1st page of pdf and phone comes in next page of pdf. That means the columns are getting divided into pages. Where as, in general, the no of rows/data may come in several pages but columns should fit into one page.
