Hello
I have an procedure downloading data from remote server, but I am running into trouble when the files are to big. I am downloading .jpg and .tif files, and sometimes they can be up to 100 mb. Are there a way to chunk the data before sending it ?
Some of my code, written in delphi (the source of this I found in : http://www.codeproject.com/aspnet/Secure_File_Download.asp)

var
req : WebClient;
myCache: CredentialCache;
minUri: Uri;
nettverk: NetworkCredential;
data: array of byte;
begin
req := WebClient.Create;
MinUri := Uri.Create(strURL);
mycache := CredentialCache.create;
nettverk := NetworkCredential.Create(strUser,strPWD);
mycache.Add(MinUri,'Basic',nettverk);
req.Credentials := mycache;

//Creating an instance of a Response object
// := HttpContext.Current.Response;
response.Clear();
response.ClearContent();
response.ClearHeaders();
response.Charset := 'utf-8';
response.Buffer := true;

data := req.DownloadData(strURL);

response.AddHeader('Content-Disposition',
'attachment;filename=' + strfile );
response.BinaryWrite(data);
end

Thanks in advance for any answers Smile | :)

i can write a subroutine that handles a datagrid's selectedindex.changed to select results from a table in a database, using the datagrid's command column as the search parameter. the problem is that i can only do this with a column that is a numbered datatype. i want to be able to do this with a column that is a string type. can someone assist me on this please. i would rather a vb.net response but iif in c# no problem.

if you have this type of problem like u are trying to get a string value on GridView.SeletedIndexChanged event from a column whish has data type "String" then simply use this property
GridViewDetail.DataKeyNames = "ColumnName";
Now after the firing of GridView.SeletedIndexChanged event u got string value.

Ooh goody. Yet another idiot trying to get people to cheat. Have you thought through the implications of this - that you are effectively complicit in fraud because you are aiding somebody to get something for financial gain through deception. In other words, people with no knowledge getting jobs for which they have absolutely no qualification.

SiteMapPath control uses a XML file, which should be placed on site's root. It's extension will be web.sitemap. Make sure that you have done all these

Do you want to get selected Datalist rows values on SelectedChanged event of dropDownList?

Where is selectedChanged Event of dropDownlist?

FInd dropdownlist control on ItemCreated event of datalist and Create EventHandler event to fire SelectedChanged Event

May be possible that you are binding Datalist on Every postback.
