We 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.

View 1 RepliesI have three values that are being generated dynamically in the code-behind of my web form. These three values will be shown to the user. While this may sound odd, I do NOT want the user to be able to copy and paste these values. Because of this, I would like to write out the values via an image that is build dynamically.
My question is, is there a way to dynamically create an image and write it out to the response? I would prefer not to create an image, save it to the server, and then pass a url back to the page. I would really like to write out the binary content along with the response.
I want to write a discount amount which is coming from a Database onto an image. I have taken an image like:

View 5 RepliesI 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.
i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

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.
I've created 2 web user controls. A = User control that displays an image, and B is the user control that hosts A. I'm trying to stream an array of bytes to A, but it seems like the Response.BinaryWrite method completely overwrites any heirachial controls (I can't see any of B's other controls besides the image).
How do I get A to just display the image from the byte stream? It doesn't come from a database, it's an image I created on the fly.
A's code:

View 6 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.
