Does anyone out there who's familiar with Scala know how I could use scala.collection.immutable.Set from Java? I can vaguely read the scaladoc, but am not sure how to call scala methods like "-" from java (I assume that I just need to include some scala .jar file in my classpath...?)
I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this. If not, how do I handle serializing a RSS feed to an object in ASP.NET?
In psql we have PL/Perl to communicate with external program when the new row is inserted into our table. Like that is there any way (procedural language ) to communicate with external program in Oracle . For achieving this things, what should I do.....?
Can any one help me out of this problem.....
I'm creating a database access layer in native C++, and I'm looking at ways to support NULL values. Here is what I have so far:
class CNullValue
{
public:
static CNullValue Null()
{
static CNullValue nv;
return nv;
}
};
template<class T>
class CNullableT
{
public:
CNullableT(CNullValue &v) : m_Value(T()), m_IsNull(true)
{
}
CNullableT(T value) : m_Value(value), m_IsNull(false)
{
}
bool IsNull()
{
return m_IsNull;
}
T GetValue()
{
return m_Value;
}
private:
T m_Value;
bool m_IsNull;
};
This is how I'll have to define functions:
void StoredProc(int i, CNullableT<int> j)
{
...connect to database
...if j.IsNull pass null to database etc
}
And I call it like this:
sp.StoredProc(1, 2);
or
sp.StoredProc(3, CNullValue::Null());
I was just wondering if there was a better way than this. In particular I don't like the singleton-like object of CNullValue with the statics.
I'd prefer to just do
sp.StoredProc(3, CNullValue);
or something similar. How do others solve this problem?
Hi,
I have an object model whose structure is
Dashboard List of panels
List of containers
List of widgets
If i get whole dashboard, with panels + containers + widgets, from Database then multiple I/O requires
I want to get it in one I/O .For this i prepared a query which gives me this resultset.
DASHBOARDID PANELID CONTAINERID WIDGETID

Using list datastructure this model is able to be filled but it takes time i want to efficiently fill this resultset in above object model. is there nay way ?
$("p").bind("click", function(event){
// code goes here
});
This is quite understandable. But what is the way to use a non-inline function and pass the event as an argument? That is:
$("p").bind("click", myFunction(event));
function myFunction(event) {
// code goes here
}
Thank you!
Hi,
I am new to iphone programming designs. I have hundreds of plists on my server. On the first launch i will be downloading all these plists into my application and storing it here. What are all the best ways to save and retrieve these plists in my application ? What are the iPhone libraries that should be used to get the best and memory efficient iphone application ?
Recently a software application we utilize upgraded from ASP to ASP.NET. In the process they abandoned the old web-based product and rewrote the entire UI, using new DB tables. The old DB tables still exist in the database and contain legacy files in binary or blob formats. I'm wondering if there is an easy way to export all these legacy files from the database to the filesystem (NTFS)? Then we could delete these old unused tables and save a few GB of space in the DB backups, etc.
I can think of a number of ways to do this in PHP or even JavaScript, but I'm wondering if there's a SQL-based technique I'm overlooking.
I have a database table, let's say 20 fields X 10 rows. I want to display the entire table on an web page, so I'd do something like SELCT * FROM data_table;, and then format the result set using HTML table tags.
However, I'd also like to highlight values in the table based on whether they are the maximum or minimum value in their column. For example, I'd add bold tags around the max in each column. A resulting table might look something like this, with bold tags shown:
id | field1 | field2 | field3 | ...
0 | 5 | 2 | <b>7</b> | ...
1 | 3 | <b>8</b> | 6 | ...
2 | <b>9</b> | 5 | 1 | ...
...
I could do a separate SELECT with an ORDER BY for each field and then interpret the results, but that seems like a lot of extra DB access.
My alternative right now is to just fetch the whole table, and then sort/search for the highlight values using PHP.
Is there a better way?
There is an image capturing device which gives its output in wmf. This output is stored in the database directly. We have cases where at times some of these images do not appear on a web page in IE. But if we right click on the page we are able to save the image on to the hard disk; meaning the image does exist on the page, but does not appear visible. I think this is because of some file corruption issue, but I don't know how to resolve it. We are however able to view such files using MS Picture Viewer (desktop app). Is there anyway we can detect such problematic files?
i want to read a file which consists of 1's and 0's in each line, how do can i store a false in any bool variable after reading 0 from the file.

I'm trying to cut a row that has the specified cell blank and then paste it into another sheet in the same workbook. My coding works fine to delete the row but everything I've tried to cut and paste keeps giving me errors. Here's the working code that deletes the rows:
Sub Remove()
'Remove No Denovo &/or No Peak Seq
Dim n As Long
Dim nLastRow As Long
Dim nFirstRow As Long
Dim lastRow As Integer
ActiveSheet.UsedRange
Set r = ActiveSheet.UsedRange
nLastRow = r.rows.Count + r.Row - 1
nFirstRow = r.Row
For n = nLastRow To nFirstRow Step -1
If Cells(n, "G") = "" Then Cells(n, "G").EntireRow.Delete
Next n
End Sub
Thanks for any help!
By best I mean most efficient.
So don't go on about subjectiveness.
I have a list of websites and I want to store the list on the iphone locally, there must be an URL, title and a small image (like 32x32 max image size). I don't think I should be using CoreData for this. Should I be using a plist?
From the docs:
You usually access to-many
relationships using
mutableSetValueForKey:, which returns
a proxy object that both mutates the
relationship and sends appropriate
key-value observing notifications for
you.
So this returns an "intelligent" NSMutableSet which automatically lets the context delete objects when they get deleted from the set, and reverse? Is that a proxy object?
I've been trying to estimate the size of an Access table with a certain number of records.
It has 4 Longs (4 bytes each), and a Currency (8 bytes).
In theory: 1 Record = 24 bytes, 500,000 = ~11.5MB
However, the accdb file (even after compacting) increases by almost 30MB (~61 bytes per record). A few extra bytes for padding wouldn't be so bad, but 2.5X seems a bit excessive - even for Microsoft bloat.
What's with the discrepancy? The four longs are compound keys, would that matter?
`public void SeparateData()
{
//read file
StreamReader sr = new StreamReader("myTextFile.txt");
//string to hold line
string myline;
myline = sr.ReadLine();
while ((myline = sr.ReadLine()) != null)
{
string[] lines = Regex.Split(myline, " ");
foreach (string s in lines)
{
using (StreamWriter sw = new StreamWriter("myTextFile.txt"))
sw.WriteLine(lines);
}
}
} `
This is what I'm doing right now:
Execute a query and check if the date
to be inserted already exists in a
table.
If date doesn't exist:
Another query will insert the date into the table.
How can these two query be combined?
I have a datamodel with to-many to-many relations. Using the example of employee database let say the entity division is related to department which in turn is related to employee. The employee has an attribute salary. How best to have a attribute at the level of division which is derived from the salary attribute. For example average salary or maximum salary.
I would need those attributes to sort the list of departments.
