with hibernate tools, i'm new to hibernate in Eclipse, so i learn how configure the hibernate and generate the POJO's with annotations (which i think is better than .xml).
So after generate my POJO's and DAO's i try to make a insertion, but launch a 'null point exception' to my entity manager, this is how hibernate tools is generating the dao classes:
Trying to use the DAO generated:

user.setEmail("[email protected]");
user.setPassword("123456");

I can see the image and I can zoom in and out correctly.
Now, I want to see scroll bars if the image is too big to show when I zoom in.
I've used the UI. I placed a **QScrollArea**. Inside, the **QLabel**.
The *verticalScrollBarPolicy* is *ScrollBarAsNeeded*.
The *horizontalScrollBarPolicy* is *ScrollBarAsNeeded*.
The problem is: it doesn't work. I zoom in, but no scrollbar appears.
Second try: using a layout inside the QScrollArea.
============================
So now there's a **QWidget** between the QScrollArea and the QLabel: a horizontal layout.
Opened the same image, now I can see a vertical scroll bar on the right. The image is streched from left to right. When I zoom the image gets its correct proportion.
BUT... I zoom out and the scroll bar is the same, even if I can see the whole image. The horizontal scroll bar never appears.
Resizing the QLabel doesn't seem to affect. But if I resize the QScrollArea (resizing the main window) the horizontal scroll bar appears.
I've been checking some numbers:
===============================
In the QScrollArea
------------------
- Its size changes: below 599 width (why this number? I can't see it anywhere) the horizontal bar appears.
- *sizeHint()* always returns the same values: 33x41
In the QLabel
-------------
- The dimensions change, but that doesn't affect.
- *sizeHint()* always returns the same values: 560x1558
What am I missing? Thank you. | image | qt | scrollbar | qlabel | qscrollarea | null | open | QLabel showing an image inside a QScrollArea

I have created a template page called new-member.php that calls in the content from another page so that when I add a new member, it is fast and easy. The path I use now is: #1) I add a new page with the company name as the title. #2 I choose the new member template. #3 I Click publish. This creates a "new member coming soon" page that is up in seconds. Perfect!
But I would like to take it to a higher level and have a php function replace "New Member" with the page title (The company name) so that when I add a new page, not only does it have the new members url, but instead of saying "New Member coming soon" it says "XYZ Company Coming Soon!" which is a temporary page until the official one is built.
Could someone please show me the correct code and where to place that code? I am using wordpress. I have no clue how to write this code. Does the code go into the new member.php template? The header? I have no idea but want to learn!

A majority of the work we do is very CMS orientated; although we've been told not to use third-party CMS' (mainly because of user's find them hard to use, and other issues), I've found that I can code a very simple CMS using Cake, CodeIgniter or one of the other PHP frameworks.
And yet, I'm getting increasingly frustrated with the amount of coding I need to do just to get something up and running, and I've been told that Django is a good Python framework to use. It also seems to get a lot of buzz from reddit.
I have some concerns and queries about moving from XAMPP to Django.
1) Security
Any web app should be coded defensively. Over the past few years we've seen a movement towards protecting against XSS, SQL injections, Cross site forgeries, session fixation, session hi-jacking, cookie hi-jacking; the amount of security one needs can be overwhelming.
What things does Django do to prevent/limit XSS, SQL injections, Javascript injections, and santizing input; one normally associates with securing PHP web apps? Is it something I need to worry about, or does Django do all this stuff out of the box.
2) What goes in the /www/ public folder?
In a manual I read it said not to put manage.py or the other .py stuff in the main webroot, so this means I put everything outside of the webroot; so what goes in there?
Do I put the /templates/ directory inside the webroot? How does the server know what to run?
3) Can I still use .htaccess on Django projects? I am familiar with Apache and often use it to do routing, or blocking off bad bots, but will using .htaccess still work?
4) Cronjobs
Do cronjobs still work with Python/Django projects?
5) Running Third party perl/other scripts
In PHP you can use other libraries such as the curl library, ffmpeg, ImageMagik as well as many others; can I still use these libraries with Python/Django?
6) Admin screen
Django gives you an out-of-the-box admin screen; is this only for development purposes or can it put live? I am concerned about any the security of the admin screen.
7) Integration with Discuss, Facebook, Twitter, OpenID, captcha, etc.
There are libraries in PHP that help integrate DisQuss, Facebook, Twitter; but is it relatively easy to do an integration with these and other third party apps?
8) E-commerce, SSL
Are there many e-commerce sites that use Django? I've seen a lot of CMS/Blog type software but not many e-commerce sites. By which I mean, shopping card, Protx/Paypal or Worldpay integration.
That's another thing; there are sandboxes for Protx, Paypal, Worldpay etc for PHP -- but are there any for Django?
9) Is it worth it?
Is it worth moving to Django from an XAMPP background? Will it really make things faster, or is that just marketing hype?

Currently doing it all in Excel, but it just isnt intelligent enough... any product suggestions?
Needs to handle multiple employees time over weeks and months... to schedule in work short-term and long-term, allow me to see possible resourcing issues etc etc.
Its an easy question answer when you work only on projects, but at my agency we work on projects and day-to-day retainer type things that can come in at any time and are usually of the "drop everything and do this now" type.
If it were just projects, then any one of the online Project Management tools (GoPlan, Copper Project, MS Project) would suffice (but definately not Basecamp, I find this ok for very small projects and small teams, but anything larger and I think it falls down completely as a PM tool)
The only thing that came close to doing all that I wanted was Workschedule - http://www.workschedule.net/
Its browser based, low-cost and has a zillion options that really allowed me to plan resource levels for the agency.

normal_limit charfield
caution_limit charfield

Now,
The below code will generate the table for oils, which has following fields.

---------
fields = ('Test Name', 'Value', 'Unit', 'Method',
'Normal Limit', 'Caution Limit')
all_oils = [(test.chemical_name, test.value, test.unit, test.method,
test.normal_limit, test.caution_limit)

('FONTSIZE', (0, 0), (-1, -1), 8),
('FONTNAME',(1,1),(1,-1),'Times-Bold')]))
Now how can I provide dynamic color for each column. Suppose my TestResult model is having field for color (I,e color=red)
In report i want dynamic color for second column which comes from model objects
How can I achieve this?

I have to take the code below and replace what the swprintf is doing and I have no idea how. My experience with low level byte manipulation sucks. Can someone please help me with this?
Please keep in mind I can't go crazy and re-write swprintf but get the basic functionality to format the pwszString correctly from the data in pBuffer. This is c++ using the Microsoft vc6.0 compiler but through CXX so it's limited as well.
The wszSep is just a delimeter, either "" or "-" for readabilty when printing.
HRESULT BufferHelper::Buff2StrASCII(
/*[in]*/ const unsigned char * pBuffer,
/*[in]*/ int iSize,
/*[in]*/ LPWSTR wszSep,
/*[out]*/ LPWSTR* pwszString )
{
// Check args
if (! pwszString) return E_POINTER;
// Allocate memory
int iSep = (int)wcslen(wszSep);
*pwszString = new WCHAR [ (((iSize * ( 2 + iSep )) + 1 ) - iSep ) ];
if (! pwszString) return E_OUTOFMEMORY;
// Loop
int i = 0;
for (i=0; i< iSize; i++)
{
swprintf( (*pwszString)+(i*(2+iSep)), L"%02X%s", pBuffer[i], (i!=(iSize-1)) ? wszSep : L"" );
}
return S_OK;
}
This takes whats in the pBuffer and encodes the wide buffer with ascii. I use typedef const unsigned short* LPCWSTR; because that type does not exist in the nutcracker.
I can post more if you need to see more code.
Thanks.

This makes the visitor logon automatically with their DOMAIN\username login which they used to logon to Windows. (Right?)

My tile server accesses a database with thousands of gps coordinates (lat,lng), and for every (lat,lng) point, checks if the point is inside the geographical bounds of the tile; if it does, coordinates conversion (WGS84 -> Mercator -> X,Y offset inside the tile) and paints the corresponding pixel inside the tile, using the GoogleMapsUtility Library.
In terms of code, I do the following:
$point = GoogleMapUtility::getOffsetPixelCoords((float)$row['lat'], (float)$row['lng'], $zoom, $X, $Y);
which calls the `getOffsetPixelCoords` function (and in turn the functions below) from the library:
public static function getOffsetPixelCoords($lat,$lng,$zoom, $X, $Y)
{
$pixelCoords = GoogleMapUtility::getPixelCoords($lat, $lng, $zoom);
return new Point(
$pixelCoords->x - $X * GoogleMapUtility::TILE_SIZE,
$pixelCoords->y - $Y * GoogleMapUtility::TILE_SIZE
);
}
public static function getPixelCoords($lat, $lng, $zoom)
{
$normalised = GoogleMapUtility::_toNormalisedMercatorCoords(GoogleMapUtility::_toMercatorCoords($lat, $lng));
$scale = (1 << ($zoom)) * GoogleMapUtility::TILE_SIZE;
return new Point(
(int)($normalised->x * $scale),
(int)($normalised->y * $scale)
);
}
private static function _toNormalisedMercatorCoords($point)
{
$point->x += 0.5;
$point->y = abs($point->y-0.5);
return $point;
}
Ok, now the results. For a zoom level<13 it works great, below is an example of a tile in Zoom level 11:
[Image1][1]
However, for a tile in zoom level >13, the following happens:
[Image2][2]
Which is so strange... the pixels seem to be perfectly aligned ? At first I thought it is a decimal resolution problem, but the resolution of the data is quite good (stored as double in a mysql database, for example, 35.6185989379883, 139.731994628906, and in php floats and doubles are the same thing...)
Could someone help me on how to fix this problem?
Thanks in advance...

Basically all the work I do involve XML in oneway of another so I thought it would be good to learn the serialization and deserialization part of the game.
My work mostly involves the 'Deserialization' part of it. Almost every time I have an XML file which has to be used by the application that I write.
An object form of the XML is the best way to use.
Now initially the XML was very straight forward, just a couple of tags which would translate into a class very easily using XSD.exe tool.
Things grew a bit complex with nesting of tags and I found Xsd2Code gen tool work fine. During this whole process I have been able to do my work with a lot of help from Stackoverflow community, thanks for that, but I think I have missed the forest for the trees.
I need to know how Deserialization works in .NET
Fundamentally, I would like to know what happens behind the scenes in taking a XML and converting it into a usable object. Code samples have helped me in the past, and as mentioned earlier the problem get's solved but the learning does not happen.
So, if anyone can guide to resources that can get me started on the Deserialization part of the game, I would be thankful to them.
Regards.

1. I need to be able to generate a picture for my space-time coordinates (not very far away from the Earth).
2. I'm hoping that this program will have a dependency NEITHER on a large/online database of images, NOR on a live satellite feed, and would instead be able to work off of an in-memory (or on-disk) colored map of Earth with projection and day-/night-highlighting calculations for creating the desired image.
3. The program should be able to run on Linux. Could be in Java, C, or any other portable/cross-platform language.
4. The program should (ideally) be able to run in offline mode... without using the Internet, that is.

When I click the ImageManager icon in the Xinha, it loads the dialog box as usual, and allows me to upload an image. Within the editor, it shows that my image is uploaded, yet when I look directly at the directory using FTP it isn't there. Also, as the image is being inserted with the text, the reference to the image appears, but the image itself doesn't.
The dialog box shows the correct directory, and (according to my web host) the security on the folders is correct. (It's a Linux based server, and the permissions on the folder are 755. I've been told not to use 777 and the files should upload ok anyway).
So, any ideas? There's no actual code to show, as it's done through the Xinha plugin, though I can copy the PHP config files if that'll help.

Actually I'm missing two concepts:

Hello I'd like to set up a web application that will use paypal as payment method.
I want that my application works as reseller. I will post on my website goods of third parties and sell them to consumers.
I'd like only to keep a fee on the transaction and just forward the money to the companyowner of the good.
Actually I'm missing two concepts:
- how these kind of transaction are performed: if the money are sent to the reseller account then on every transaction the amount-fee% will be forward to the seller. Or if the money are sent directly to the seller and he will payback my company the fee.

I have a windows service which has a very intensive process that is always running, I have put this process onto a separate thread so that the main thread of my service can handle operational tasks - i.e., service audit cycles, handling configuration changes, etc, etc.
I'm starting the thread via the typical ThreadStart to a method which kicks the process off - call it workerthread.
On this workerthread I am sending data to another server, as is expected the server reboots every now and again and connection is lost and I need to re-establish the connection (I am notified by the lost of connection via an event). From here I do my reconnect logic and I am back in and running, however what I easily started to notice to happen was that I was creating this worker thread over and over again each time (not what I want).
Now I could kill the workerthread when I lose the connection and start a new one but this seems like a waste of resources.
What I really want to do, is marshal the call (i.e., my thread start method) back to the thread that is still in memory although not doing anything.
Please post any examples or docs you have that would be of use.

Apart from dimensions both sport similar configuration but a unique point about the QF+ is the presence of a unit **PLX 8647**.
Google shows that it is a PCIe switch. Now how will the PCI lanes differ in these two motherboards. How does the switch kick into action. The OEM says that it 48 lanes supporting full length 3 x16 slots. Doesn't with 2 Intel 5520 IOHs the lane count double from 36 to 72?
Suggestions please

When we make a click, for example, on the top layer inner_child_2, the event will propagate to all event handlers registered to inner_child_2 and its parent outer_container. Not to inner_child_1 despite it is directly below inner_child_2. This is by specification. All modern browsers do it.
My question is this:
How to make an event pass through inner_child_2 and reach inner_child_1, besides making inner_child_1 not visible or change its z-index?
(Or transparent, but this will only work in IE8)
I thought about triggering an event myself in some handler code registered to inner_child_2. But in the real usage case, I don't know where to dispatch the event, as below inner_child_2, there are multiple elements laid out in unpredictable fashion and I want each one to receive events as if inner_child_2 was not there. Ideally, I want to be able to selectively let some events pass while keeping others out.

And there are plenty of alike methods you can define (`__eq__`, `__str__`, `__repr__` etc.).

On Step 1, I have a drop-down list that uses a Javascript function to reconfigure some of the fields in the same Panel via "onchange". Obviously, since the client-side script is only affecting the DOM, when I go to Step 2 and then back up to Step 1, the fields in Step 1 are back to their orignal configuration even though the same drop-down choice is selected.
What is a good method for storing the visual state of the Panels between steps? I considered calling the drop-down's onchange function on page load, but that seemed clunky. Thanks! | c# | panel | state | null | null | null | open | Good way to maintain ASP.NET Panel states?
