Save BinaryWrite to Server Path

Save BinaryWrite to Server Path

I am saving files to SQL Server on remote hosted server. I can upload
them. But I need to download a file to the remote servers path. The code
below extracts the file but saves it to the client.
I tried replacing Response.BinaryWrite(bytes) to Response.TransmitFile(
Server.MapPath("~/App_Data/DS/sailbig.jpg") but I get an error file not
found.
I simply want to extract the file I stored in sql and place it a the
directory on the server so I can use it in code later, but I cannot figure
it out. Any help is appreciated, this is a hobby for me.
Dim filePath As String =
HttpContext.Current.Server.MapPath("~/App_Data/DS/")
Dim bytes() As Byte = CType(dt.Rows(0)("Data"), Byte())
response.Buffer = True
response.Charset = ""
response.Cache.SetCacheability(HttpCacheability.NoCache)
response.ContentType = dt.Rows(0)("ContentType").ToString()
Response.AddHeader("content-disposition", "attachment;filename=" &
dt.Rows(0)("FileName").ToString())
Response.BinaryWrite(bytes)
Response.Flush()
Response.End()

Servlet-Applet communication

Servlet-Applet communication

I have an applet successfully signed and deployed in my application.
I have a index.html which loads the applet correctly if I make a call like
/myApp
However,if I try to forward to index.html from a servlet, I´m getting a
ClassNotFoundException.
Here are the code that loads the applet.All these jars are in the
WebContent folder.
index.html
<applet code="com.griaule.grFingerSample.FormMain"

What am I doing wrong?

iOS Core Data: How do I add subsequent records to the 'many' of 1:many relationships?

iOS Core Data: How do I add subsequent records to the 'many' of 1:many
relationships?

I am writing an GPS running app that I want to store multiple locations
per 'Path' or run. I am having a little trouble understanding the new
concepts of ORM style DBs. (I know Core Data uses SQLLite as the
underlying mechanism and isn't a true ORM, but that aside..,) I have two
entities setup, 'Path' and 'Location', with a 'To-Many' relationship going
from Path>>Location with Cascade Deletion, and an inverse that just has
nullify for Delete.

I am doing:
//SEND TO CORE DATA
bdAppDelegate *appDelegate =
[[UIApplication sharedApplication] delegate];
NSManagedObjectContext *context =
[appDelegate managedObjectContext];
// get GPS lat/lng
double lat = newLocation.coordinate.latitude;
double lng = newLocation.coordinate.longitude;
// insert Path
Path *currentPathInfo = [NSEntityDescription
insertNewObjectForEntityForName:@"Path"
inManagedObjectContext:context];
currentPathInfo.name = currentPathName;
currentPathInfo.createddate =[NSDate date];
// insert location/GPS point
Location *currentPathLocation = [NSEntityDescription
insertNewObjectForEntityForName:@"Location"
inManagedObjectContext:context];
currentPathLocation.lat = [NSNumber numberWithDouble:lat];
currentPathLocation.lng = [NSNumber numberWithDouble:lng];
// insert 'Location' relationship to 'Path'
[currentPathInfo addLocationsObject:currentPathLocation];
NSError *error;
if (![context save:&error]) {
NSLog(@"Whoops, couldn't save: %@", [error
localizedDescription]);
}
This is on initial startup (button press) but then how do I continue to
add more 'Locations' that relate to the initial 'Path' without continuing
to add more 'Path's as a result of repeating the above code?
In SQL, I'd have a PathID integer (identity) that I'd use for a foreign
key in a 'Locations' table to insert locations... I'm having a
disconnect...

setting css styles usign jQuery

setting css styles usign jQuery

I need to set the css styles to the following elements as follows using
jQuery
#hdr-nav-wrapper ul li:hover a{
background-color:#0294ca;
}
#hdr-nav-wrapper ul a:hover{
background-color:#00aeff;
}
Except that the actual color will have to be dynamic based on whatever the
background color of a div with id of "TestDiv". This site has a theme
engine where users can change colors using a color theme palette. I am
appending a nav bar to the top of the site but I want to have the
background of the nav bar as the same as whatever "TestDiv" currently has.
How do I convert the above css to jQuery with that dynamic logic?

Please help identify on which partition I have ubuntu installed

I need to reinstall my GRUB since I cannot boot windows 8 anymore
(something happened with my installation of Ubuntu). I want to follow this
advice - Boot error > no such device: grub rescue in order to re-install
the grub but I made the stupid mistake of allocating half of the size of
the partition to windows and half to Ubuntu lol. So now I need to know on
which partition I have Linux could someone help me out ? Thanks. Here is
the partition list
