olowing: response.BinaryWrite(myStream.ToArray());response.End();ser gets saving dialog and he can chose to save file or to cancel saving. But, problem is that can't continue to run code if user chooses to cancel download or, if he chooses to save file. I want to call another method afther that to update some tables in database, but I can`t do this.
View 1 RepliesThe required functionality I am aiming for is to pull out RTF content from a database, edit it through a web interface (with a WYSIWYG editor) and then place the modified text back in to the database (in RTF format).
The control that I am using to do this is Telerik RadEditor (we have a license already for these controls). In the most recent version there appears to be functionality to load in RTF content from a string or a stream, but the only method I can see that is exposed for getting RTF back out is exportToRTF(); this method modified the headers and allows you to save a RTF version of the content you have just edited as a file.
The functionality to convert from HTML to RTF must exist somewhere within their library as you can export a RTF file, but I can not find any publicly exposed methods to pass this in to a stream or a string.
Does anybody know of a way that I can convert the HTML back to RTF using the Telerik libraries without saving out to a file?
Is it possible to open a file from a MemoryStream?What is really important is that i do not want to save the file to disk first.
View 3 RepliesI have a function that downloads an image from a DB, saves it to a Temp directory and passes the string back to an app that opens it. Ran fine with .NET 2.0, but throws a variety of exceptions in .NET 4.0. (like System.AccessViolationException was unhandled).It somehow seems to relate to the saved file still being locked.

Im generating a PDF file. Normally I send this to the user using a .ashx file, where the user can directly download it from his browser (see that code below).
Protected Function getfile() As MemoryStream
Dim stream As MemoryStream = New MemoryStream
If document.PageCount > 0 Then
document.Save(stream, False)
'Context.Response.Clear()
'Context.Response.ContentType = "application/pdf"
'Context.Response.AddHeader("Content-disposition", "attachment;filename=TicketEZ_tickets_" + eventname + ".pdf")
'Context.Response.AddHeader("content-length", stream.Length.ToString)
'Context.Response.BinaryWrite(stream.ToArray)
'Context.Response.Flush()
Return stream
stream.Close()

I'm trying to attach a memorystream as an attachment to an email, however the file is always empty. I'm using a streamwriter to write the text in to the memorystream, I then flush the streamwriter and I can see the memorystream has data. However when I attach the memorystream to the email the file is always empty. I can't see what I'm doing wrong. The code is:

I trying to display image in picture box. The application have two part.First part is windows application, and second part is web service (asmx).This is the code for windows application:

PictureBox1.Image = Image.FromStream(p.PictureShow()) [code]....
The problem is that function in web service does not return System.IO.MemoryStream data type so I getting error message can not convert:

I have a file, a.pdf, stored on a SharePoint server behind Windows authentication. I want to make a.pdf available through another Web app with forms authentication. Basically, link is clicked and up pops the open / save as dialog for the pdf (or other document file) I've set up my HTTPWebRequest and passed credentials, getting my data into a stream (file.GetResponseStream).
I've tried converting the stream to a byte array and then using response.write or response.output.write with no luck (stream not seekable) I've tried using a streamreader and doing a response.write(streamreader.readtoend()) and response.write(memorystream.toarray(),0,memorystream.toarray().length) with no luck (the message received from the server could not be parsed).
I have an small ASP.NET application that reads data from a table and sends it out as an excel attachment in an email message. The data is simply HTML table tr td tagged data. The way I am sending the message is by the following code:
byte[] data = GetData(excelData);
MemoryStream memoryStream = new MemoryStream(data);
mm.Attachments.Add(new Attachment(memoryStream, "info.xls", "text/plain"));
This has been working fine in Excel 2003 but for some reason Excel 2007 keeps trying to convert the whole thing to a formula and I get a "Cell Data too Long" error. I've tried searching but couldn't really find anything specific about why this might be happening in 07 or a simple way to fix it. I know 07 probably handles data a little bit different than 03 but I don't have a lot of time to dedicate to reworking this app if possible.

i was able to get it to work, but i think there is a problem havingtwo different datareaders whiles within another. after moving it outof the outer while in a method it works. The Exception from the 1st update was because i didn't closed the reader, so it opened too many tables an JET crashed on the 2048 open tables. So but i'm not very pleased with the result, but at least the data comes out
View 2 RepliesAlthough Enable Edit and Continue is checked on the Web tab of my ASP.Net MVC 2 project, I cannot in fact change the source code while running. For example, if I try to edit a controller while paused in the debugger, I cannot change the file (acts as if read only).
I found a related post Edit and continue in ASP.NET web projects, however
The answers seem to suggest I should be able to at least edit the code, then reload the page to see the result.I don't know what the distinction is between a Web Application and Web Site projects
I am completely stuck here. Basically, I am serving a file to the user by sending it using Respnse.BinaryWrite. I am also sending this on a redirected page so as not to destroy the Response stream of the webpage which fired the filedownload. This works perfect on my development machine, it also works perfect on Firefox.However, if I publish to my test server, on IE 8 (and 7 I presume) a security warning bar appears (does not appear in dev mode on my pc), asking the user to accept or decline the file. Now the not-so-funny thing: If the user accepts, the file is NOT served, I just get back to my main webpage. If the user tries a second time to get the file the security question will NOT pop up again and the file is served.How can I make sure the file is served in the first instance if the user accepts the security warning and wants to download?

HttpContext.Current.Response.ContentType = "application/pdf"
HttpContext.Current.Response.BinaryWrite(myReportData.ToArray)

View 1 RepliesI had written a piece of code in MVC 1.0 and the Response.Redirect worked flawlessly.I now have a new application and I decided to use MVC 2.0 but that same piece of code is now not working. After the Response.Redirect is called, the code STILL continues to execute. I have not seen this in any version of ASP.NET until now. Usually, after Response.Redirect is called, execution of all code is stopped.
Why is this now happening and how do I fix this? this is very frustrating to me and I cannot seem to find a solution.
Right now I have an error if f.ParentID is null:
