ashx

问题 I have employee images stored in my EMPPhotos table on SQL Server 2008 R2 in an image datatype. I created a generic handler to get the image from the table and send it to the page. It does not work. I have tested the query itself and I am getting data. The handler: <%@ WebHandler Language="VB" Class="EmpImageHandler" %> Imports System Imports System.Web Imports System.Drawing Imports System.Drawing.Imaging Imports System.IO Imports System.Data Imports System.Data.SqlClient Public Class

问题 I have a handler, like this, using IRequiresSessionState: public class MyHandler : IHttpHandler, IRequiresSessionState { // code } In the code, I am able to read and set Session values. I also check ensure that the caller is logged in. That all works fine. The web site uses forms authentication, so in the web.config, I have this: <authentication mode="Forms"> <forms loginUrl="Login.aspx" timeout="10" slidingExpiration="true"></forms> </authentication> The problem is that AJAX calls from the

问题 I have an ashx file which returns a localised message. This is called from an Ajax request. I need to access the Asp.net ResourceManager in the ashx file. 回答1: Following code worked for me. HttpContext.GetGlobalResourceObject("classKey", "resourceKey") as string; 回答2: Any resources in the app should be accessible under the Resources namespace. For a resource file called LocalMessages.en.resx: ReturnMsg = Resources.LocalMessages.MyAjaxMessage; For intellisense to work, make sure app has been

问题 We have a lot of files, saved as binary in our SQL Server database. I have made an .ashx file, that delivers these files, to the users. Unfortunately, when the files become rather large, it will fail, with the following error: Overflow or underflow in the arithmetic operation I assume it runs out of memory, as I load the binary into a byte[]. So, my question is, how can I make this functionality, read in chunks (maybe?), when it is from a database table? It also seems like Response

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . I plan on building a simple, yet high usage webapp and need to settle on an architecture. basic server side logic / dynamic db driven content about half a dozen to a dozen pages serving up all said content no need for URL rewriting, pretty simple page flow/routing The

问题 We are providing downloads of our application setups through an ASHX handler in ASP.NET. A customer told us he uses some third party download manager application and that our way of providing the files currently does not support the "resume" feature of his download manager application. My questions are: What are the basic ideas behind resuming a download? Is there a certain HTTP GET request that tells me the offset to start at? 回答1: Resuming a download usually works through the HTTP Range

问题 I have an ashx handler which takes the 'html' property from the request, then returns that back to whatever called it. I also have the Content-Disposition set as attachment. Calling the page directly works as expected, forcing a download with a save as dialog. What I'm stuck on is this: I need to do this from javascript (jQuery). I'll be posting the content of a div and do some further processing. Could someone give me some pointers on how this is done? Many thanks. 回答1: I would (in fact, do

问题 I'm not sure of the best way to approach this, but here is my scenario. Let's say I have an ashx handler that feeds out some data to an ajax request from the client. Something simple like: public class Handler : IHttpHandler { private List<MyObject> data; public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { data = GetData(); string result; switch (context.Request.QueryString["requestType"]) { case "case": result = Foo.Bar(data).GetJSON(); break; //

问题 I've been using the past few hours attempting to figure out why the Paypal Sandbox IPN Simulator isn't detecting a Content-type on my request back. I didn't modify any of the code where the request back is made, so it's odd that it's not going through correctly. There was a similar question back in March, though the answer he marked didn't seem to do the trick for me. Does anyone have any idea on why this is happening? Has this happened to anyone else recently? public class PaypalIPN :
