and also tried....
public ActionResult Edit(UpdateUser model)
{


try
{

UserDTO user = new UserDTO();
user.UserName = model.UserName;
int User_Id = user.UserID;
//new UserHandler().Update(user,int.Parse(User_Id));
new UserHandler().Update(user, User_Id);


return RedirectToAction("Details", new RouteValueDictionary (new { id = user.UserID}));
}
catch
{
return View();
}
}

now i tried this but the same error is arising ...
public ActionResult Edit(UpdateUser model, string User_Id)
{
try
{

UserDTO user = new UserDTO();
user.UserName = model.UserName;

new UserHandler().Update(user,int.Parse(User_Id));

return RedirectToAction("Details", new RouteValueDictionary (new { id = user.UserID}));
}
catch
{
return View();
}
}

public ActionResult Edit(int id)
{
UserDTO user = new UserDTO();
//USER user = database.USERS.Find(id);
//return View(user);
user.UserID = id;
SetViewBagData(id);
return View(user);

}

// POST: User/Edit/5
[HttpPost]

public ActionResult Edit(UpdateUser model, int user_Id)
{

try
{
UserDTO user = new UserDTO();
user.UserName = model.UserName;

new UserHandler().Update(user, user_Id);

return RedirectToAction("Details", new RouteValueDictionary (new { id = user.UserID}));
}
catch
{
return View();
}
}

i change id in edit action to user_id...
and its giving me exception here

its giving me exception over this line....Value cannot be null
ViewBag.RoleId = new SelectList(r.Role.OrderBy(p => p.RoleName), "RoleID", "RoleName");

how can i save image data in the database?????????

That error has been removed....
now when i call the GetPrivilige() function it gives me error....
Cannot implicitly convert type 'System.Collections.Generic.ICollection<DTO.RoleDTO>' to 'System.Collections.Generic.ICollection<DTO.PriviligeDTO>'. An explicit conversion exists (are you missing a cast?)
here is what i am trying....

public ICollection<roledto> GetPriviliges()
{
var query = (
from p in db.PRIVILIGES
from r in p.ROLES
select new
{
Priviliges = p.Description
}
).ToList() as ICollection<roledto>;

return query.ToList();
}
here is code where i am calling GetPrivilige function....
public List<roledto> GetData()
{
var query = from r in db.ROLES
select new RoleDTO
{
ID = r.ID,
RoleName = r.RoleName,
Description = r.Description,
Priviliges = GetPriviliges()
return query.ToList();
}

public ICollection<roledto> GetPriviliges()
{
var query = from p in db.PRIVILIGES
from r in p.ROLES
select new
{
Description = p.Description
};
return query.ToList();
}

I am doing this to get the priviliges associated with the role but this error is coming....

Cannot implicitly convert type 'System.Collections.Generic.List<anonymoustype#1>' to 'System.Collections.Generic.ICollection<DTO.RoleDTO>'. An explicit conversion exists (are you missing a cast?)

How can i do that

i don't have any idea of how to add OUTCURSOR

how gave you this assignment???????????

yep

me using oracle 11g

now this is giving error at line 2 when i write @seq_name varchar2,
SP2-0310: unable to open file "seq_name.sql"

then how else i can do this????? please help.....

but for checking to play with computer the withComputer() i have made payerone and only computer two true then why its doing this.

evaluation does not proceed... it gives the exception
Unable to cast object of type 'System.Char' to type 'System.String'.

the exception is coming at this point
if (((String)realtokens[j] == "dint" || (String)realtokens[j] == "dig" || (String)realtokens[j] == "chart") && ident((String)realtokens[j + 1]) == true && (String)realtokens[j + 2] == ":")

the same thing

i tried....
still its not working......

it only displays when in '' there is a single word but there are many words it didn't work

i have tried that but still its not working

i don't know how to use Regex.......

'this is my string'
this is the input i am giving and it should be displayed as that it is a string literal but its ignoring white spaces and does not display anything.
but when i use only single word like 'this' without any space it displays it is a string literal...

bool startSym = ss.StartsWith("'");
bool endSym = ss.EndsWith("'");
string strr = ss.Substring(1);
bool strliteral = strr.Any(char.IsLetterOrDigit) || strr.Any(char.IsPunctuation) || strr.Any(char.IsSymbol);
// bool invalid_str = strr.StartsWith("'") && startSym && strliteral && endSym;
// string strspace = ss;
bool areThereAnyLetterOrDigitsInStrrAtAll = strr.Any(c => char.IsLetterOrDigit(c));
//bool space = strspace;
//&& strr.Any(char.IsSeparator)
if (startSym && strliteral && endSym)
{
//if (invalid_str)
if(areThereAnyLetterOrDigitsInStrrAtAll)
{
MessageBox.Show("Error: Line num " + linecount + " Invalid String Literal b/c of multiple starting symbol");
errorcount++;
break;
}
// if (ss.Length > 2) //valid string literal
else
{
MessageBox.Show("this is a String Literal");
break;
}
}

not working still.........

thanx its working.....

okay going to try it

then can you tell me how to do it....

it diplays that the number is real number either it has one or two dots.
