Tiff - How To Display Image That Is Located On Another Server On The Network
Apr 13, 2010
I'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:
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 trying to post data from vb.net application to web service asmx that is located on server! For posting data from vb.net application I am using this code:
Public Function Post(ByVal url As String, ByVal data As String) As String Dim vystup As String = Nothing Try 'Our postvars Dim buffer As Byte() = Encoding.ASCII.GetBytes(data) 'Initialisation, we use localhost, change if appliable Dim WebReq As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest) 'Our method is post, otherwise the buffer (postvars) would be useless WebReq.Method = "POST" 'We use form contentType, for the postvars. WebReq.ContentType = "application/x-www-form-urlencoded" 'The length of the buffer (postvars) is used as contentlength. WebReq.ContentLength = buffer.Length 'We open a stream for writing the postvars Dim PostData As Stream = WebReq.GetRequestStream() 'Now we write, and afterwards, we close. Closing is always important! PostData.Write(buffer, 0, buffer.Length) PostData.Close() 'Get the response handle, we have no true response yet! Dim WebResp As HttpWebResponse = DirectCast(WebReq.GetResponse(), HttpWebResponse) 'Let's show some information about the response Console.WriteLine(WebResp.StatusCode) Console.WriteLine(WebResp.Server) 'Now, we read the response (the string), and output it. Dim Answer As Stream = WebResp.GetResponseStream() Dim _Answer As New StreamReader(Answer) 'Congratulations, you just requested your first POST page, you 'can now start logging into most login forms, with your application 'Or other examples. vystup = _Answer.ReadToEnd() Catch ex As Exception MessageBox.Show(ex.Message) End Try Return vystup.Trim() & vbLf End Function
I inherited a web site that has a web page that displays images of properties for an online property/tax info. Using VB code, it searches for a main image then creates and saves smaller images for use as thumbnails. Currently it gets the images from a directory on the web server. The images are copied to the web server via a job from another server on our network. I am trying to code the page to get the images directly from the original server and having trouble doing it. Here's the code. Point of failure is indicated:
[Code]....
The server error: "Parameter is not valid." How can I get this to work?
$('#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 gridview which displays thumbnails in the first column and details in the other columns. The thumbnail URL is being retrieved using the following:
[Code]....
However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).
To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?
I wish to add a sub to vb file that changes the display value of several asp:panels located in a Formview Item Template. My only question is what is the proper event to run this in. (databound, item created etc...) If it matters this formview appears in a Gridview Item Template.
I have a silverlight client that i want to get and write data to a DB located on the server . now this is what i did :
1. created the silverlight projecte hosted in asp site project, with wcf enabled . 2. created a DB with some tables in it. 3. created linq to sql classes, and wcf service with operation to fetch data from the DB, added the project the referance .
result:
when i debug it locally on localhost, it workes perfectly, but when i upload all the content to the server i get an error, my guess is that the service is not finding the DB . after I uploaded the content, all i did was change the connection string in my web.config file to the one provided to me by the hosting server. exception:

I want to show .nfo file to user.That nfo file is located on server and i am giving it's path in crystal report.
So, when user click on that path of nfo file in crystal report, i want to show that file to user.
I cannot open nfo file in browser.I got this error,

I want to grant access to some ressources located on server only for specified web pages, how could I do this?
For example I have an image www.mysite.com/images/image.jpg and something like <img src="www.mysite.com/images/image.jpg" /> should only work on site asp.net.
Is it possible with web.config or maybe with some C# code?
I have a project that must illustrate that connection to the database is not locally, so I have install VirtualBox and I intend to install SQL Server on it. So any one have the idea of how can I connect from the Host Machine to the SQL Server located on the Virtual Machine
I have a code which creates an image in application server and that image has been referred in mail html. After sending mail, image will be deleted in application server. When i open the mail , image is not getting display in the mail.
The reason i guess is , my code is deleting the image before it copied to mail server. I have checked by deleting the image manually.
First i opened the mail(this time image get copied to mail server) and then deleted the image in pplication server. When i open the mail 2nd time, image get display(because image is in mail server i guess)
Again i ran the code, this time before opening mail first time, i deleted the image in application server and opened the mail. Image is not displaying(because image not getting copied to mail server).
