how does the code within the <% .... %> brackets write to the output stream of a view?
Where view code that looked like the following would write the HTML for a <table> to the output html of the view.
<%
ToViewOutput( "<table>" ) ;
ToViewOutput( "<tr>" ) ;
ToViewOutput("<td>row1. cell 1.</td>") ;
ToViewOutput("<td>row1. cell 2.</td>") ;
oViewOutput("</tr>") ;
ToViewOutput("</table>") ;
%>
I have an excel file in my Response Output stream. I can Open the stream as a file after a prompt, but it doesn't seem I can save it directly to a specified folder on my client.

I have run into the issue on DataSet.WriteXml method. Apparently, if any row in a column in the DataSet has a null value, the entire column/rows will not write out in the xml file using the method DataSet.WriteXml. So, as terrible as that bug is, I need to send the data another way. Does anyone have any thoughts?
Is there a recommended or good way to stream the output messages asynchonously to a web form so there's some indication of progress? A bit like TeamCity does for build scripts. Should I be polling a webservice? Using the OutputDataReceived event? Turning off buffering?
View 2 RepliesI would like to read all content that's been written to the output stream. I'm attempting to do this using an HTTP module, and it seems like the obvious timing would be when handling the PreSendRequestContent event.
However, if the output stream seems to be set to write-only, as I can't read using a StreamReader. Is there a way I read and re-write the content without writing my own IIS module?
Is there some way to intercept the HTML output stream in asp.net and make modifications? Eg using httpmodules or something? I know this is possible using java servlets and assume there must be an elegant way to do this with asp.net.
My purpose is to combine the many javascript files into one composite script which has been minified/packed, to make the page load faster.Eg, if my page normally outputs the following in the page head:
<script type="text/javascript" src="/scripts/blah.js"></script>
<script type="text/javascript" src="/scripts/yada.js"></script>
I want to replace that with the following:
<script type="text/javascript" src="/scripts/all.js"></script>
(also i realise i'll have to create all.js somehow).
I've got an asp.net application (written in vb.net). I have a results page that spits out some calculations. Ineed to write out that output to MS Word. The catch is, this happens within a folder that is secured (only users that are logged in can generate
the word document).
Here's what I'm using to gen the document. This works ok when running it locally, but not when loaded to GoDaddy hosting.
[Code]....
My code seems works fine locally. However, after loading it to GoDaddy it only works on a non-secured (not subject to ASP Membership), but when trying to use it in a secured folder the page clocks and eventually closes out.

I am using Visual Web Developer Express with VB.net and have a website with 2 pages in them called "Tables.aspx" and "Variables.aspx". On the Tables page the user is required to enter a variable name in to a texbox, which I want then to take the user to the Variables page and have the gridview display the sql result. In behind the search button on the "Tables.aspx" page I have the following code.
Code:
' Search button code
Dim search As Char
Search = CChar(txtSearch.Text)
If Search = "" Then
MsgBox("You cannot leave this field blank.")
[code]....
On the "Variables.aspx" page I had decided to use data readers which brought up only one of the columns however I realised using data readers would mean I would have to individually position each textbox which I am not sure how to do.
Basically what I would like to know is how I do get the result of sql= "SELECT dbo.NILS_tables.Table_ID, dbo.NILS_variables.Variable_Name, dbo.NILS_ variables.Variable_Description FROM dbo.NILS_variables JOIN dbo.NILS_tables ON dbo.NILS_tables.Table_ID = dbo.NILS_variables.Table_ID WHERE dbo.NILS_tables.Table_Name LIKE '%' OR dbo.NILS_tables.Table_Description LIKE '%' " on to a gridview on the "Variables.aspx" page? NB the code for the search button is stored in the code behind file on the "Tables.aspx" page.
Is there a way (except for using JS on the html view) to tell asp.net to run a certain code on client side (instead of server side)?
View 4 RepliesI want to execute a piece of code. Currently it is written in Page_load().
Because of this my application becomes slow.
Is there any other option where can i write the code?
i am doing a webapplication where any asp.net control i am using is not available while i am writing code in code behind. e.g- i am using a DataList but i did not find DataList1 in the pop up to show my data in .cs page. i dont know what is the problem .
i am using Visual Studio 2008 pro SP1.
So here is what I would like to do. Lets say I have a view that can do multiple things, and thus talk to several different controllers. For example, it might create a new group, or change the name of an existing group, or add a user to some group. Now, for the view to display correctly, it would only need the username, a list of groups, and possibly a list of users. Yet for the controllers to work they would need a different set of information, the userid to be added to a group, the name of a new group, or the name and id of a group to edit.
With this setup, there would be a potential of several different models for both input to the view, and output to the different controllers. I like the idea of using the helpers Html.Textboxfor() ect. to create the different submission elements, but I don't so much like the idea of having one giant model (Even if it just a model that inherits or has several sub models) that gets passed around everywhere for this view. It seems...
Perhaps there is a better way to do this (if so, feel free to smacking me around with a few "Your and idiot"s) but is there any way to have a separate input and output model for a view?

View 1 RepliesI'm trying to test the login control without writing any code. According to Murachs book, you can drag and drop the login control onto a Login.aspx form. Use the ASP Configuration Security tool to create user, roles, and access rules for the website. And you should then be prompted for authentication. I created two folders in my website, admin and users. The admin folder has a admin.aspx form and the users folder has a users.aspx form. I also edited the access rules to only allow admin to access the admin.aspx and only allow user to access the users.aspx form.
View 4 RepliesWe have encountered this difference in file creation while using a HttpHandler Versus a Code Behind Aspx page. We are reading a saved jpg/png picture as byte array from a 'Image' field in sql server database and create a physical file in the server. Both the Aspx Page and Httphandler use the same code pasted below.
//Begin
int docID = Convert.ToInt32(Request.QueryString["DocID"]);
var docRow = documentDB.GetDocument(docID);
// Retrieve the physical directory path for the Uploads subdirectory
string destDir = Server.MapPath("../../Uploads").ToString() + "\";
string strFileName = destDir + DateTime.Now.ToFileTime() + "_" + docRow.DocName.ToString();
FileStream fs = new FileStream(strFileName, FileMode.CreateNew, FileAccess.Write);
fs.Write(docRow.DocData, 0, docRow.DocData.Length);
fs.Flush();
fs.Close();
// End
After the file is created, it is viewable as a jpg/png Image only in Aspx Code Behind. While in case of HttpHandler it is not a valid Image.

I'm using a hosting service and I tried putting the default pages (that you get when you make a new website in web developer) onto the hosting service. But they only show up "normally" when I change the extension to html. if it's .aspx it just shows the code.
Question is how can I view the aspx file in the browser from the website normally without using "View in Browser" in that popup menu in Visual Studio Web Developer? And side note I can't use IIS (don't know if that's important but other places talked about it)
