Simply put, I'd like someone to be able to click a link, and get a one-time-use pdf. We have the library to create PDF files, so that's not an issue.
We could generate a link to an aspx page, have that page generate the pdf, save the pdf to the filesystem, and then Response.Redirect to the saved pdf. Then we'd somehow have to keep track of and clean up the PDF file.
Since we don't ever need to keep this data, what I'd like to do instead, if possible, is to have the aspx page generate the pdf, and serve it directly back as a response to the original request. Is this possible?
(In our case, we're using C#, and we want to serve a pdf back, but it seems like any solution would probably work for various .NET languages and returned filetypes.)
I have a requirement to build a simple ASP.NET web page which sends some parameters to a web service, and then displays the string which was returned. I'm a complete .NET newby and the only examples I can find seem really really complex. I just need something mega simple, but which an handle parameters being sent to the web service. Can anyone point me in the direction of a simple bit of C# which will do this with no frills or fuss?
im working on a MVC 3 webapp where i want to post to a controller function using jQuery ajax. However, every time i post to the server i get a 400 Bad Request response and i can't figure out where this comes from as the site runs fine with the VS2010 devserver.
See the function im using to send the ajax post below:
I am trying to the following to return xml response from an http request
Code: Try Dim id As String = Request.QueryString("id") Dim xmlOut As String = "" cn.ConnectionString = "Data Source=192.168.1.2;Initial Catalog=db;Persist Security Info=True;User ID=sa;Password=pass" dad = New SqlDataAdapter("select * from tbl where id = '" & id & "'", cn) ds.Clear()
[Code] ...
Is there some other way to do this without having to resort to writing the xml to a temp file on C drive and reading it again to display the output ?
Reporting system has list of available reports on a web page. When user clicks on a report new browser window opens, server starts to prepare report (winword document) and then sends it back after 2-10 seconds.
We just moved an ASP.net application to a new server and are now getting this error when we try to return to a page: Http/1.1 Service Unavailable
In testing, I find that the address of the page does not include the SSL designator. It is trying to use http:// instead of https://. This value is coming from the Context.Request.Url property of the page.
why Context.Request.Url would not return the "https" for a page under SSL?
i am experiencing this error when i try to browse one of the application.The same app is working fine in the morning but when i tried to debug the app i am facing the error .Now i removed the debugger but still am facing this error.
When user requests http://localhost/WebApp1/Default.aspx, txtApplicationPath.Text should be assigned "/WebApp1", while txtAbsolutePath.Text should be assigned "http://localhost/WebApp1/Default.aspx", but instead both textboxes display empty strings.
I created a httpHandler that successfully implements IHttpHandler for handling file uploads. It works perfectly fine. You send the file with the form, the class receives it and will save it to hard disk. It reads chunks of file with ReadEntityBody function of HttpWorkerRequest class.
Here is the situation i'm faced with.If at any stage before trying to read the file with ReadEntityBody, I try to access Request object (even Request.InputStream.Length!) ReadEntityBody would return 0 means it won't read from file stream.
After further testing I found out the reason behind it. Accessing to Context.Current.Request object will trigger some sort of functionality that will cause asp.net to handle file uploads at that moment by it's own! I believe this is a bug.
for example exactly after this line of code, asp.net will upload the file completely, and so there will be no stream for ReadEntityBody to read from later.
int FileSize = context.Request.InputStream.Length;
I have the following code where the function codeaddress geocodes the text feild value and returns geocoded value , geocoded value is stored in variable example ,how will i return the variable v2 to the function call and post to asmx webservice.
I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
Can my WebMethod return an XmlDocument as return type?
When I try to consume the web service I'm still not getting XML. It appears as though a reference to the method is being returned rather than say a string containing XML.
<WebMethod()> _ Public Function CustomerSearch(ByVal lastName As String, ByVal firstName As String, ByVal companyName As String, ByVal city As String, ByVal state As String, ByVal email As String) As XmlDocument ' Create XML doc Dim doc As XmlDocument = New XmlDocument() ' some more code Return doc End Function
I have a webservice which works 100% fine on my developer machine. Where Web Service is installed on LOCALHOST on my developer machine,Then i went to my servers, I installed webservice on one server and map it with the server where the website is hosted, Then i tried accessing this service using BROWSER from my web server, it worked fine, That means the mapping was done perfect.Then i run my program on web server (website). It worked fine on page1, then on page2, but when i did the same and call same function on page3, It popped me any error of
Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.
when i browse the page with firefox and click on the input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is statisfied.
When i browse the same page with internet explorer 8 and click on the same input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is not satisfied. When i used the watch i saw that there is no key by the name of "btnshoppingCart" in either Request.Form or Request.Params if input is clicked from internet explorer. However when it is clicked from firefox there is value "shoppingCart" inside Request.Form and Request.Params against "btnshoppingCart" key. One more strange thing that i observed was that are two keys "btnshoppingCart.x" and "btnshoppingCart.y" inside both Request.Form and Request.Params whenver clicking is done from both internet explorer and firefox. This is happening against all inputs of type image irrespective if the input is present inside a html form or not. Forms are created like this
<% using (Html.BeginForm("Action", "Controller", FormMethod.Post)){%>
The version of internet explorer is 8.0 and firefox is 3.6.6
I there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) { context.AuthenticateRequest += new EventHandler(AuthenticateRequest); } protected void AuthenticateRequest(object sender, EventArgs e) { app = sender as HttpApplication; if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) { // a few requests do not enter here, but my webservice class still executing // ... } } I have disabled HTTP POST and HTTP GET for webservices in my web.config file. <webServices> <protocols> <remove name="HttpGet" /> <remove name="HttpPost" /> <add name="AnyHttpSoap" /> </protocols> </webServices> Looking at ContentType for soap+xml only partially solves my problem. For example, Cache-Control: no-cache Connection: Keep-Alive Content-Length: 1131 Content-Type: text/xml Accept: */* Accept-Encoding: gzip, deflate Accept-Language: ro Host: localhost mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).
I develop an asmx web service (i.e. ASP.NET 2.0). There's a piece of code that may read the contents of the HTTP request (via HttpContext.Current.Request.InputStream) while processing it. I realise that InputStream may only be read once for a request, and I make sure I never try to read it more than once.
The problem seems to be that if InputStream happens to be read during the early stages of the application's lifecycle (e.g. after pskill w3wp, during Application_Start), the HTTP request fails with a HTTP 400 - Bad Request error, with no explanation given, no exception thrown and no entry in the httperr log. If it is read later (e.g. within the web method itself), requests run fine whether InputStream is read or not. Application_Start runs fine if InputStream isn't read.
Is this some sort of ASP.NET bug? IIS bug? Or am I doing something wrong by daring to read InputStream? And if so, is there another way to get a look at the "raw" contents of the request without disturbing the inner workings of IIS/ASP.NET? In short, adding this code within Application_Start is enough to reproduce this error: using (StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream))reader.ReadToEnd();
I am trying to use curl to access 3rd party webservice, I used the following code which works well if I try it on my own linux server, the data is being sent ok, but the IIS on the 3rd party server returns an error.
$longdata is a long string of data, maybe over 1000 characters long the 3rd party has many working clients with various implementations so the problem is on my side. what do I need to add to the request in order to get this through ?
How to get asp.net return drop down list to return value as int
I want to pass the value to a stored procedure as an integer. But the default appears to be as a string which is not what the store procedure is expecting.
Is there a good way to return the list values as ints?
I suspect I can you set the value on the change selection event, is there another way?
