View 1 RepliesIve created a Web App where it is possible to download an xml file from the server to the client. It works just fine except that the Save Dialog recognizes the file being dowloaded as of type .aspx and the name of the file as being the name of the page I' on. The page is called Download.aspx and it contains a button that when clicked executes the following code:
[Code]....
The save dialog appears and says:
Name: Download.aspx
Type: ASP.NET Server Page, 1,16KB
From: 127.0.0.1
If I download the file and open it it contains the correct Xml file content and nothing else, so it is working correctly. It just annoys me that it appears to the user that he is downloading the aspx site (and it shows up as such in windows explorer as well) rather than the xml file which is the actual content.
I have an existing project with a silverlight3 app. First I created SALESservice.svc.This is working fine. Now I added another TARGETservice.svc to my project and rebuilded my entire project but when I am trying to add the service reference in to the silverlight app I get the following error:
There was an error downloading metadata from the address.verify that you have entered a valid address. I didn't write any code in ISALESservice.svc AND ITARGETservice.svc . I have written in SALESservice.svc.cs AND TARGETservice.svc.cs files.Is this causing error? But for SALESservice.svc it is working. I didn't add any code in web.config file.
All the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:
[Code]....
So how can i just return ViewData["SqlError"] message in page.
I want to redirect to Error.aspx page if runtime error occurs.How to acomplish this task.
View 8 RepliesI am generating an aspx page which then I need to convert to png and store it somewhere. A similiar situation with mine was asked before here but got still no response. I tried also the code that the Swapnil Fegade has asked but the code is looping continually making request to loading page and no conversion is actually being done.I found some solutions on the web also but they require WebBrowser control which i understood can be used in windows form but i am building a web project.

View 3 Replies In trying to upload images to a server, I often get the following error "Maximum request length exceeded.".
I have tried to check for the size in codebehind but it appears that the error comes from the service provider or something else because I never even get to debug it since the error appears even before the Page_Init Subroutine in codebehind.
What is the best method of checking for the image size and then resizing it dymamically to a maximum file size as well as length and width size.
I have two files. The first file is called FinalImage.aspx and here is the code for that page:
<html>
<body>
<img src="newpage.aspx" />
</body>
</html>
newpage.aspx has the following code, based on Jason's sample in the comments below:
<%@ Page Language="C#" %>
<script runat="server" language="c#">
protected void Page_Load(object sender, EventArgs e)
{
Response.ContentType = "image/png";
byte[] data = System.IO.File.ReadAllBytes("http://mystatus.skype.com/smallclassic/eric-greenberg");
Response.OutputStream.Write(data, 0, data.Length);
Response.OutputStream.Flush();
Response.End();
}
</script>
If I call FinalImage.aspx I see a broken image.
If I call newpage.aspx directly, I get a "URI Formats are not supported error"
I think its close, though. this solution is needed to get around the fact that skype does not have an https option for its skype buttons which tell the status of the skype user. Creating this proxy page will allow this to work without causing a 'mixed' security alert in the browser.
I am using a custom error page in IIS 6:<customErrors redirectMode="ResponseRedirect" mode="On" defaultRedirect="Error2.aspx"/>I want to disable authentication for the custom error page because the error being raised is related to an authentication module and I don't want to get into an infinite loop and I want to display a clean error page to the user. I have been trying the following configuration to do that.
<location path="Error2.aspx">
<system.web>

I am trying since more than 5 days to retrieve and display an image in a web page, no success so far.1. I have a table named image, with three fields ImageID, Img_data, Img_contenttype .2. I am able to display the ImageID as a link in my page.3. On clicking the link i am going to my viewImage.aspx?img=ImageID .This far it works ok. ImageID is passing in the query string.4. In this page imageID is being captured from query string and stored in ImageIdview int variable. viewImage.aspx has an image tag to display the image as below.

i got following error when downloading ZIP file having size 4GB the error says
The size parameter must be between zero and the maximum Int32 value.
Parameter name: size
Actual value was 2166897372.
In my ASP.Net page, I allow users to download files from the server. If the file is of even a moderate size (does it with a 40 meg file, for example), when downloading, it fails with the error message:
"Insufficient system resources exist to complete the requested service".
I've checked out the server, and it's quiet (CPU, RAM, Hard Drive, Task Manager Processes, etc all very low in their numbers).
I've run the code from several client machines and I'm getting this error message no matter where I run it from.
I have read about the file upload control in asp.net and tried it and works great. But I want to know if I can use it for another purpose. I have a video capture control that can be used for webcam apps or anything else. It has a method called HTTPUpload where it will upload an image file to the server using the HTTP upload protocol. My question is can i use the .net FileUpload control for this? And if so, how can I pass the image file straight to the .aspx page without having to submit a button? Would the file be as a query string variable?
Arguments:
WebServer = web server address
WebPage = name of upload web page
Fields = list of 'fieldname' and 'fieldvalue' values delimited with '|'
Files = list of 'fieldname' and 'file path' values delimited with '|'
Returns TRUE if successful, or FALSE otherwise.
Example
vcx.HTTPUpload "[URL] , "upload.asp",
"field1|value1|field2|value2" ,
"file1|c:foldermypic.jpg|file2|c:foldermyvideo.avi"
