Hi,
I am created a web application such a type that user can upload the image by drag image from window explorer and drop in web page. Obviously drop image should be on one animation control only. user can see dropped thumbnail images over web page. and then by single click user can upload the images.
Means in single line Drag and Drop and Upload.
Note:Image path retriving from listbox.These path generated when user is dropped the image.
Here we have not using any html inputFile control.
So my problem is,I can not uploading images on server from client machine.But it is working fine on Local PC.
Can any one give me solution for this?
Thanks in Advance!!!!![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

FileUpload has SaveAs method to save file on server.
But as per ur requirement u have to download image from server and save to server
are every images on server?
If yes try this code
MemoryStream stream = new MemoryStream();<br />
System.Net.WebClient wc = new System.Net.WebClient();<br />
byte[] image;<br />
string path="ImagePath";<br />
image = wc.DownloadData(path);<br />
int indx = path.LastIndexOf("/");<br />
path = path.Substring(indx + 1);<br />
stream.Write(image, 0, image.Length);<br />
Bitmap bmp = new Bitmap(stream);<br />
bmp.Save(Server.MapPath(path));
Hope this will be helpful
Best Regard

Because in Local PC your ASP.NET account will have Read/Write permissions. But in your client machine, it don't have permissions.
Is your application working on Intranet ? Then you can permit ASP.NET account to access files contained in the specified folder.But if it is working internet, I think that you need to get HTTPPostedFile class object to perform uploading. But getting this from ListBox seems to be impossible.

Hi,
On the close event of the window, I want to call a button click event which is present on the server side. so in the body tag in the onload() i am calling the button click event as follows:
<body bottomMargin="0" onunload="formclose();">
function formclose()
{
var res
res = confirm("Do you want to draft this mail, attachments will not be saved.")
if(res == false){
window.opener = self;
window.close();
}
if(res == true)
{
alert(res);

I suspect the form is closing before your method call can do anything. A click involves a postback. A postback involves the page reloading. The page can't close, and reload.

You need to Encode the url. Use Server.URLEncode

ASP.NET has no built in support for Flash. However, it's just an HTML engine, you can embedd any HTML you like. Assuming that the thing you need to buy lives entirely on the server, it must just be sending HTML, it's question of working out what script you need to write.

Hi,
I have this webpage that displays rows of data (using asp:repeater) and has a checkbox on the status column.
I also have a drop down list box of various status (e.g. started, completed, on hold, etc) and a button.
I need to user to check the data that he/she wants the status to be updated, choose the status (from the list box) and then update the database when they click on the button and the page refreshes
How can I go about doing this, within the same page? I tried doing it the ASP way (go through the names of the checkboxes and update accordingly) but it seem it doesn't work (not surprised there). It seems that the asp repeater gives the check boxes ids like ct100_content_output_ct101_cb.
Any help is greatly appreciated.

Hi Pathan,
Thanks for the reply, but I don't get your "looping of Repeater.Items.Count", doesn't this just count the number of items that have been selected?
My page is like this.
<br />
ID Name Status<br />
1 name1 [checkbox] Started<br />
2 name2 [checkbox] Completed<br />
3 name3 [checkbox] Started<br />
4 name4 [checkbox] On hold<br />
<br />
[drop-down listbox] [submit]<br />
It means the user can check anyone of the boxes to change the status, I just can't see how counting the checkboxs would help.
I'm sorry if this is a redundant question but I'm really confused about asp.net.
Thanks.
Desmond

Hi, I get the exeception Value of 'Byte' cannot be converted to '1-dimensional array of Byte' when I run the following code.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim connect As String = "Data Source=localhost\sqlexpress;Initial Catalog=pubs;Integrated Security=True"
Dim sqlconnect As New System.Data.SqlClient.SqlConnection(connect)
Dim sqlcommand As New System.Data.SqlClient.SqlCommand("select * from Doc")
sqlcommand.Connection = sqlconnect
Dim dr As System.Data.SqlClient.SqlDataReader
sqlconnect.Open()
dr = sqlcommand.ExecuteReader()
While dr.Read()
Dim filename As String = dr("Title").ToString()
Dim contentType As String = dr("DocType").ToString()
Response.Clear()
Response.ContentType = contentType
Response.AddHeader("Content-Disposition", "attachment;filename=" + filename)
Response.BinaryWrite(CByte(dr("ContentDoc")))
Response.[End]()
End While
sqlconnect.Close()
End Sub
The line that is causing that problem is Response.BinaryWrite(CByte(dr("ContentDoc"))). Please help me fix this problem, thank you in advance for your help.
