how to take clone of an Input Stream. I want to take clone of file uploaded through file upload control. ie clone of fileUpload1.PostedFile.InputStream;
I need to develop a new functionnality for one of our application.
Basically, what i want to develop is a way to let the user draw a semi-transparent rectangle over a static image. The principle could be the same as mspaint. The user click on a button a then, can draw his rectangle over an image.
i have an image button that i draw with its data in the runtime and i want in the event og onclick of it, apopup model appears to confirm delete or update that row. the problem is here that i made alot of searches but all i found was in the design time.
My web page contains a file upload control that is used to select excel file. What my code does; is to read the content of that file and store its content to DB. Right now, I save this file to server and read its content using OLEDB.I want to know is there any way i can read the content without saving it on the server?
I am trying to add row in DataTable CartDT using row[], which is a string array.
DataTable CartDT = new DataTable(); public void DataTableColumn() { CartDT.Columns.Add("Product_Name", typeof(string)); CartDT.Columns.Add("Product_ID", typeof(string)); CartDT.Columns.Add("ItemQTY", typeof(string)); CartDT.Columns.Add("Price", typeof(string)); CartDT.Columns.Add("TotalPrice", typeof(string));
[CODE]..
Now when I execute it, it gives the error that "Input array is longer than the number of columns in this table" The array row[] has exactly 5 elements in it & also DataTable CartDT has also 5 columns. Now i am not able to find exactly where i am wrong.
I've looked everywhere and googled everything and couldn't find anything good. What I need is a class that is able to draw an image (graphics) with rounded corners (different on each corner is a plus) with a border and gradient fill.
All the examples I find have some flaws (like bad quality, missing functionality etc).
I will use this with a ashx that will draw the image and then show it to the user.
in previously asked question answeres said they dont get what i want to do exactly so heres is the full code also i simply want that instead of a TABLESe i rendered an image( of the content ) on the page
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.IO; using System.Text; using System.Data; using System.Drawing; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { System.Web.UI.WebControls.Panel panelmain = new System.Web.UI.WebControls.Panel(); System.Web.UI.WebControls.Literal abc = new System.Web.UI.WebControls.Literal(); abc.Text = "as<br/>dasdas<br/>dasdad"; DataSet ds = new DataSet(); DataTable dt; DataRow dr; DataColumn idCoulumn; DataColumn nameCoulumn; dt = new DataTable(); idCoulumn = new DataColumn("ID", Type.GetType("System.Int32")); nameCoulumn = new DataColumn("Name", Type.GetType("System.String")); dt.Columns.Add(idCoulumn); dt.Columns.Add(nameCoulumn); dr = dt.NewRow(); dr["ID"] = 1; dr["Name"] = "Name1"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["ID"] = 2;.............
Is is possible to update an image on an HTML page using the response stream of an ASP.NET Generic Handler? For example, if I have the following code on a handler: [URL]
How can I call the handler in jQuery, using .ajax, and set an image on the page equal to the image that is returned by the Handler? I am ignoring the query string variable at the moment as I just want to get this working. Secondly, if I can do above, how can I loop through all of DIVs on the page that are of class "content", select a guid out of a hidden field to use as my query string parameter, and update the associated image within the same content DIV tag? A content div tag would look as follows:
I would like to have all the images updated on a periodic interval, so essentially, as a quick recap, I would need to have: A loop through all of my DIVs of class "content", occuring every n. seconds. Extractation the GUID from the hidden field. A call to my ASHX handler to get the updated image. Set the returned image to the corrisponding image on the page. Is this something that would be difficult to achieve? If not, what would I need to do to make this function in the above manner?

I have a folder with png images that are not shared or public (the folder is outside my application folder). Now I want my users to be able to view thoose images only if they are logged in (different users, different images). All images have a name that correspond to the users id. My idea is to stream thoose images into the asp:Image control, is that possible? How do I do that? Other (better) solutions?
Is there a control that you can use? It can be done by fetching a binaryread from an aspx page but why there isn't a simple free image control that you can put in the page and feed it a byte array?
I have a grid with an template column and in that column I have text and icon, on icon mousehover (on mode) and mousehoverout (off mode) I am changing the icon.
Now when the user click on icon it opens a popup and the icon must be in "On" mode but if the user without closing clicks another row's icon then previous must be in off and current should be in on mode.
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
