Is is possible to write to the http response stream from a dynamically created bitmap using the Response.Write/WriteFile without saving the image to the hard drive?
1. after user click on one of the buttons another ones doesn't response
2. I need to execute some code after user received file (delete copy of it from the server)
I suppose I need to open another window and call SaveFile dialog from it. But how can exactly do this? I've found example code of opening window or starting SaveFile dialog but not two of them together and I can't figure out how to put them together...
I've just installed VS 2010 RC and IIS7 with .NET framework 4.0 on a Windows 7 laptop (and I'm very new to this).
I'm trying to use Response.WriteFile to add a menu to an .aspx page, and it works but it also adds two square/unknown characters before the inserted text. Also, when I view the source of the displayed webpage in IE8, the source gets up to the point of the two squares, then shows an opening angle bracket (<) and then stops, although the rest of the webpage displays fine.
It doesn't matter whether the included file has any text in it or not, or whether it is an .html or .aspx file.
Response.Write doesn't have the problem.
(In FF and Opera, the inserted text is displayed as html code with a space (opera) or unknown character (FF) between each normal character. I'm not worried about those browsers as I'm developing soley for IE8)
I have a button that calls a click event to download a picture. In my click event I have some code to change my display as the Save dialog pops up. The issue I am having is that when the dialog comes up it stops the previous line of code from executing. How can I check to see that my code has executed before calling the function?
which shows a prompt to download the file and the prompt by default has "Open", "Save" and "Cancel" buttons with "Cancel" selected by default.Is it possible for me to hide the "Open" button and force users to eitehr save or cancel?
I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)
i am calling a function which is inside Homescroll.ascx.cs from Homescroll.ascx so i wrote on Homescroll.ascx as <% Response.Write(scroll()); %> but all this is in update panel,and i am getting errors. so is their any other way to call function from homescroll.ascx to homescroll.ascx.cs,instead of response.write();
Response.Write("<script id=""mycountry3"" language=""Javascript"" src=""http://www.ip2phrase.com/ip2phrase.asp?template=You are from Country: <COUNTRY> ""></script>")
in showfile.aspx, I send the file using Response.OutputStream.Write method. now I get some problem when somebody put this webpage in an IFrame and open in IE, as I checked the code, showfile.aspx is requested twice when clicks the link, and in the second time the cookies of authorization and session Id are missing. I tried to add the p3p header but not working.my question is, is this how the IE designed with iframe? is there anyway to work around?
The variable id is declared and it's value set eralier in the method.When the new window opens it displays the image properly, but the existing page suddenly loses all of it's styling. The links double in size and change font family. Does anyone know a way to retain styling on the calling page?
I want to use response.write to generate a table. but I have a question, the result of table must display on the top of web page. How can I control the location of table? e.g. at the middle or end of web page or starting from number of line.
i am posting some data from my application to an external website i.e for a credit card payment
so i am using a response.write object.how to display the reposnse.write in a new window
this is my code
Dim sb As New StringBuilder() sb.AppendFormat("runat=server") sb.Append("<html>") sb.AppendFormat("<body onload='document.forms[""form""].submit()'>") sb.AppendFormat("<form name='form' action='{0}' method='post'>", postbackUrl)
There are files stored in sql server (datatype of column is varbinary in the database).
each record is in one record in that table (FILE_TABLE).
And there is another table (PATH_TABLE) to store the files paths.
for example,
when the user download the folder A (select an item on the tree and click a button on the client side),
there is one sub-folder B and two files A-1 and A-2.
in folder B, there is two files B-1 and B-2.
then, at the code behind (server), the server will get the files from the database and convert them (including the files and subfolders) to a .zip file (or other compressed files)
and then write a response (using the method HttpResponse.BinaryWrite(Byte[] xxx) )
to client side and let the user download.
after the download, the user can extract the compressed file and the structure of the folders and files keep unchanged.
Let me explain better than what the question state. I dynamically generate a KML file from an aspx page and use routing to change the url so I can access myapp.com/mykml.kml and the download starts. I use Response.write() in the aspx page to send the data and it work flawlessly. But there is a zipped version for KML files which is KMZ and I am wondering if I can still use my aspx page to serve a KMZ instead of a KML. Since I do not use a file I cannot "zip" it. Is there a way to zip the stream and output it in the Response.Write()?
