I have learned quite a bit browsing through Hidden Features
of C# and was surprised when I couldn't find something
similar for VB.NET.
So what are some of its hidden or lesser known features?
i have something that requires a matrix of values, similar to pokemon:
i have a class object for each of the types, is there a pattern or a good way to implement this, as a middle layer or in the classes?
I am looking for an example which does a file upload with a progress bar, in Django.
I have been trying djangp-uploadify for quiet sometime, but have not been able to get it working.
I have been trying something similar to that given in http://stackoverflow.com/questions/2821612/djangouploadify-dont-working/2887831 and also in http://wiki.github.com/tstone/django-uploadify
Quick Help would be great
Im not sure if this question is appropriate to go in here but after some hard effort in google I had no option but to post this here.
I'm in the process of doing some UIs for a touch screen, but not sure how the template should look like. e.g. how big the buttons/text/labels should be. If anyone has experience in doing s similar stuff, pls share some references you have.
thanks

I have an actionscript 2 application that I'd like to write automated UI testing for.
For example I'd like to simulate a mouse click on a button and validate that a movie-clip is displayed at the right position and in the right color... Basically, UI testing.
What are the best tools available or what is the desired approach?
In JavaScript there is the selenium framework which does a nice job. Any similar tool for flash?
From within Java, I am opening an Excel file with the default file handler (MS Excel, in this case :-) ) using the method described in this stackoverflow question:
Desktop dt = Desktop.getDesktop();
dt.open(new File(filename));
However, the Excel program doesn't get the focus. Is there any easy way to do so?
Edit: There is a related stackoverflow question for C#, but I didn't find any similar Java method.
I tried Xceed datagrid for WPF and liked it, but the problem is that this vendor doesn't have similar control for Silverlight. It seems for me that it's not very convenient to buy it from some another company and have components from different vendors for such close thechnologies as WPF and Silverlight.
Could you share your thoughts and experience on this? What whould you recommend?
I've read like 10 or so "tutorials", and they all involve the same thing:
Pull a count of the data set
Pull the relevant data set (LIMIT, OFFSET)
IE:
SELECT COUNT(*)
FROM table
WHERE something = ?
SELECT *
FROM table
WHERE something =?
LIMIT ? offset ?`
Two very similar queries, no? There has to be a better way to do this, my dataset is 600,000+ rows and already sluggish (results are determined by over 30 where clauses, and vary from user to user, but are properly indexed of course).
Does psycopg2 have a function for escaping the value of a LIKE operand for Postgres?
For example I may want to match strings that start with the string "20% of all", so I want to write something like this:
sql = '... WHERE ... LIKE %(myvalue)s'
cursor.fetchall(sql, { 'myvalue': escape_sql_like('20% of all') + '%' }
Is there an existing escape_sql_like function that I could plug in here?
(Similar question to How to quote a string value explicitly (Python DB API/Psycopg2), but I couldn't find an answer there.)
Dear All,
I would like to automatically generate a flowchart similar to this one ( http://en.wikipedia.org/wiki/File:%281%29_2008-04-07_Information_Management-_Help_Desk.jpg ) with Python.
Do you have any advice regarding the library I should use to draw boxes, arrows (with the shortest path), text and some colors.
Many thanks in advance !
On this site if you do too many clicks or post comments too fast or something like that you get redirected to the "are you a human" screen. Does anybody know how to do something similar?
How can I pass data from client to server?
I have a very simple text editor created on a site and every few minutes or so I would like to send the information that has been typed in back to the server as a text file. I am trying to create an effect similar to the live type of googleWave.
Speed and efficiency isn't all that important at the moment. A quick and dirty way would be suffice.
Does ASP.NET's ScriptManager have any sort of "helper" for binding to HTML control events? This would be similar to jQuery:
$('#foo').bind('click', function() {
alert('User clicked on "foo."');
});
In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example:
mydict = {'a': [3,5,6,43,3,6,3,],
'b': [87,65,3,45,7,8],
'c': [34,57,8,9,9,2],}
for k in mydict.iterkeys():
print k
gives me:
a
c
b
How can I do something similar in Javascript?
I have 2 similar queries
select *
from openquery(powerschool,
'select *
from TEACHERS
where teachernumber is not null
and schoolid=''1050''
and teacherloginid is not null
order by teachernumber')
and
SELECT *
from openquery(powerschool,
'SELECT NVL(teachernumber,'''')
from TEACHERS
where teachernumber is not null
and schoolid=''1050''
and teacherloginid is not null
order by teachernumber')
The first one is giving me 182 rows while the second one gives me 83.
What's wrong with the queries?
I saw this video, and I am really curious how it was performed. Does anyone have any ideas? My intuition is that he scraped pixels from the screen (one per 'box'), and then fed that into some program to determine the next move.
Is scraping pixel-by-pixel the way to do this, or is there a better way? I am looking to do something similar with either Java or Python.
Thanks
My HTML page contains many tables,with numerous tr and td. While rendering in IE8/IE9 the
its very slow but in Firefox its fast. I had read somewhere while drawing tables if the tables are not of fixed width, IE calculates the width every time and renders so usually slow.
Right now i am adding Table style="table-layout:fixed" which made me feel its faster.
Are there any similar styles that can be added to tr and td as well.Also
suggest if there any other attribtes that can be added to a table
I want to make a table that displays on a webpage, but one requirement is to make it easy to copy and paste into a spreadsheet. Normal HTML tables selection behavior is obviously different from how a spreadsheet like Excel selects -- when you select multiple rows it wraps around instead of selecting a rectangular area. Is there any way to make HTML table behave like a spreadsheet in this regard, or is the only way to resort to a Flash table or something similar?
Hi all,
I would like to dynamically create a PHP object, and parameters would be optional.
For example, instead of doing this:
$test = new Obj($param);
I would like to do something like this (create new ob is fictional):
$test = create_new_obj('Obj', $param);
Is there such function in php? Something similar to call_user_func_array, but for object instead.
I'm trying to define a class (or set of classes which implement the same interface) that will behave as a loosely typed object (like JavaScript). They can hold any sort of data and operations on them depend on the underlying type.
I have it working in three different ways but none seem ideal. These test versions only allow strings and integers and the only operation is add. Adding integers results in the sum of the integer values, adding strings concatenates the strings and adding an integer to a string converts the integer to a string and concatenates it with the string. The final version will have more types (Doubles, Arrays, JavaScript-like objects where new properties can be added dynamically) and more operations.
Way 1:
public interface DynObject1 {
@Override public String toString();
public DynObject1 add(DynObject1 d);
public DynObject1 addTo(DynInteger1 d);
public DynObject1 addTo(DynString1 d);
}
public class DynInteger1 implements DynObject1 {
private int value;
public DynInteger1(int v) {
value = v;
}
@Override
public String toString() {
return Integer.toString(value);
}
public DynObject1 add(DynObject1 d) {
return d.addTo(this);
}
public DynObject1 addTo(DynInteger1 d) {
return new DynInteger1(d.value + value);
}
public DynObject1 addTo(DynString1 d)
{
return new DynString1(d.toString()+Integer.toString(value));
}
}
...and similar for DynString1
Way 2:
public interface DynObject2 {
@Override public String toString();
public DynObject2 add(DynObject2 d);
}
public class DynInteger2 implements DynObject2 {
private int value;
public DynInteger2(int v) {
value = v;
}
@Override
public String toString() {
return Integer.toString(value);
}
public DynObject2 add(DynObject2 d) {
Class c = d.getClass();
if(c==DynInteger2.class)
{
return new DynInteger2(value + ((DynInteger2)d).value);
}
else
{
return new DynString2(toString() + d.toString());
}
}
}
...and similar for DynString2
Way 3:
public class DynObject3 {
private enum ObjectType {
Integer,
String
};
Object value;
ObjectType type;
public DynObject3(Integer v) {
value = v;
type = ObjectType.Integer;
}
public DynObject3(String v) {
value = v;
type = ObjectType.String;
}
@Override
public String toString() {
return value.toString();
}
public DynObject3 add(DynObject3 d)
{
if(type==ObjectType.Integer && d.type==ObjectType.Integer)
{
return new DynObject3(Integer.valueOf(((Integer)value).intValue()+((Integer)value).intValue()));
}
else
{
return new DynObject3(value.toString()+d.value.toString());
}
}
}
With the if-else logic I could use value.getClass()==Integer.class instead of storing the type but with more types I'd change this to use a switch statement and Java doesn't allow switch to use Classes.
Anyway... My question is what is the best way to go about something thike this?
Is there a similar logic for logout using this login code:
// login account
def autht = new AuthToken(username, password)
def authtoken = daoAuthenticationProvider.authenticate(autht)
SecurityContextHolder.context.authentication = authtoken
I checked LogoutController and this is the only logic for logout:
redirect(uri: '/j_spring_security_logout')
Any idea? Thanks
I would like to obtain the list of controls under a given point.
There is a method on System.Windows.Form to obtain a control under a point(GetChildAtPoint) but not point(GetChildsAtPoint).
Is there something similar for the list of controls (if borders intersect one other):
I need this because I select the objects when user clicks on the panel(I use Microsoft.VisualBasic.PowerPacks.RectangleShape as label bellow). In case if labels are superposed, user should be asked what object to select.
Hi,
Is it possible to get a list of all applications installed in a Blackberry, similar to the applications list when you go into your settings.
I can get a list of all visible applications using the following but I was wondering if it's possible to get a list of apps that aren't necessarily running but are installed,
ApplicationDescriptor[] descriptors =
ApplicationManager.getApplicationManager().getVisibleApplications();
Hi,
Does anyone know of a way to obtain the phone service state (IN_SERVICE, OUT_OF_SERVICE, EMERGENCY_ONLY, POWER_OFF) in android.
I was hoping there would be a broadcastreciever to identify the changes, but I can't find anything. I know there's a listener but I'm not sure how I would use that from my app as it runs as a service using a WakefulIntentService (by thecommonsguy).
With something like battery level (ie BATTERY_LOW, BATTERY_OKAY) it's quite easy, but I just can't work out a similar things for phone service changes.
