Does any one know of an example on how to store an image in a SQL Server CE database?
What data type should the column be? (I am guessing binary.)
I use Linq-To-Datasets. Is it possible using that to put the image into the database and pull it out again later?
Thanks for any advice.
For a custom made IE toolbar, can I simply call SetRedraw() from onDocumentComplete() ?
Does it allowable? or will it work if I put some Sendmessage inside SetRedraw()?
component A (in C++) - is blocked waiting for alarm signals (not relevant) and IO signals (1 udp socket). has one handler for each of these.
component B (java) - has to receive the same information the component A udp socket receives. periodicaly gives instructions that should be sent through component A udp socket.
How to join both components?
it is strongly desirable that:
the changes to attach component B to component A are minimal (its not my code and it is not very pleasent to mess with).
the time taken by the new operations (usually communicating with component B) interfere very little with the usual processing time of component A - this means that if the operations are going to take a "some" time I would rather use a thread or something to do them.
note: since component A receives udp packets more frequently that it has component B instructions to forward, if necessary, it can only forward the instructions (when available) from the IO handler.
my initial ideia was to develop a component C (in C++) that would sit inside the component A code (is this called an adapter?) that when instanciated starts the java process and makes the necessary connections (that not so little overhead in the initialization is not a problem).
It would have 2 stacks, one for the data to give component B (lets call it Bstack) and for the data to give component A (lets call it Astack). It would sit on its thread (lets call it new-thread) waiting for data to be available in Bstack to send it over udp, and listen on the udp socket to put data on the Astack. This means that the changes to component A are only: when it receives a new UDP packet put it on the Bstack, and if there is something on the Astack sent it over its UDP socket (I decided for this because this socket would only be used in the main thread).
One of the problems is that I don't know how to wait for both of these events at the same time using only one thread.
so my questions are:
Do I really need to use the main thread to send the data over component A socket or can I do it from the new-thread? (I think the answer is no, but I'm not sure about race conditions on sockets)
how to I wait for both events?
boost::condition_variable or something similar seems the solution in the case of the stack and boost::asio::io_service io_service.run() seems like the thing to use for the socket.
Is there any other alternative solution for this problem that I'm not aware of?
Thanks for reading this long text but I really wanted you to understand the problem.
We use self signed certificates on our intranet. What do I need to do to get IE8 to accept them without showing an error message to the user? What we did for IE7 apparently isn't working.
EDIT: IE7 wouldn't show any errors if I put the certificate into trusted root certification authorities. IE8 seems to show errors even with the certificate there.
Hi,
I am trying to change the default style of a DataGridCell (within a WPF Toolkit DataGrid) when there is a validation error. The default is a red border. How can I put my own template?
Thanks.
Hi Everyone,
I'm specifically using the Google Contacts API at the moment, but this could be true of other scinarios as well.
I have the following code:
Contact newContact = new Contact();
When I let the code run without any breakpoints, I get a NullReferenceException on all of the properties of this object. However, if I put a breakpoint just after this line, I can see all of the properties have been initialises and the rest of my code executes fine.
Any idea's would be greatly appreciated
Hey Guys,
I have a asp.net website and I am accessing that web service from my iPhone app to get data.
The WCF web service produces data as JSON.
I want to put some kind of authentication on the WCF. What you you guys recommend?
Thanks
I am using the Mac OS X Apple Script Editor and (while debugging) instead of writing a lot of display dialog statements, I'd like to write the results of some calculation in the window below, called "Result" (I have the German UI here, so the translation is a guess). So is there a write/print statement that I can use for putting messages in the "standard out" window? I am not asking to put the messages in a logfile on the file system, it is purely temporary.
I'm looking for a decent open source salon management system to recommend to a friend. I've considered writing a new system in .Net but the website aspect is already covered. What's really required at this stage is an decent reservation and stock management application that I could put in place for them.
If there are recommendations for commericial pacakages which are reasonably priced I would also like to hear them.
Thanks.
when i put ajax on my code I send a group of variable via post but when i received the data it is in a obj.responseText ie TEXT format.
say i have two files "form.php" and "index.php"
ajax is implemented in form.php while index.php returns the text.
but my problem is index.php also generates a variable named "tarriff_count"
i want to catch systematically and separately this variable,
Is there any systematic way to catch variable.also keep in mind "obj.responseText" is very complicated to get a variable from "preg_match" ?

I need to customize my jTable. All I need, is to put a custom Swing object (like jButon, jPanel, etc.) into the table cell. Is it possible? I'm trying:
jTable.getModel.setValueAt(jPanel1,0,0)
and
jTable.getModel.setValueAt(jPanel1.getUI(),0,0)
But the result is only a some kind of string, representing the object... Any ideas?
I get an "unrecognized HTTP method" when trying to do a REPORT request using httplib and gae. Is there a workaround available? An httplib patch for gae? Do you I have to find another host in order to do this natively?

I'm using the net.sf.json.JSONObject to create some data to be sent to a front end application, and I don't like the ways ts adding quotation marks to every field name.
For example:
myString = new JSONObject().put("JSON", "Hello, World!").toString();
produces the string {"JSON": "Hello, World"}.
What I want it to return is {JSON: "Hello, World"} - without quotes around "JSON". What do I have to do to make that happen?
I just realized that you can't just use an if statement on a function, for example this doesn't work:
function sayHello()
{
echo "Hello World";
}
if(sayHello())
echo "Function Worked";
else
echo "Function Failed";
I also saw that a function can't be put as the value of a variable. So how can I do an if statement to check if a function has executed properly and display it to the browser?
We are using VB.NET and ASPx for our project. we would like to separate the aspx pages and put them on the IIS server (web server) on one m/c and the business logic and DAL layer on another IIS server (application server) on a different m/c .The database is on another m/c. Is such a configuration possible ? If so how can it be implemented?
Suppose user enter this string at terminal

How do I scan these three (could be more) numbers in different variables in python
Could be something like this:
for i in range(1,n)
m[i]=#WHAT FUNCTION SHOULD I PUT HERE
In c++ we can easily use cin>>m[i] inside above loop to scan the variables.
If i use input() or raw_input() , they would scan whole line in single variable.
I want to get the ID of an element I click on.
I put the function in the onclick element, like this:
<a id="myid" class="first active" onclick="markActiveLink();" href="#home">Home</a>
And this is in the function:
function markActiveLink() {
alert($(this).attr("id"));
}
This doesn't work, as it says it isn't defined.
Does it really forget about the ID, do I have to type it in the onclick?
Looking for some [freeware/opensource] tool in order to make it easy to profile a big php project on win32 platform. Need to find out which part of code is most time consuming.
It's hard to manually put timing function for each function, loop...
Hi,
how do I set the value of a field element after a form has been submitted but has failed validation? e.g.
if form.is_valid():
form.save()
else:
form.data['my_field'] = 'some different data'
I don't really want to put it in the view though and would rather have it as part of the form class.
Thanks
I am working on a Geocoding app where I put the address in the URL and retreive the XML. I need the complete XML response for this project. Is there any other class for downloading the XML from a website that may be faster than using WebClient or HttpWebRequest? Can the XMLReader be used to get the full XML without string manipulation and would that be faster and/or more efficient?
I have a controller method with the following signature:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult UpdateValues(int id, MyViewModel[] array)
{
}
The id is normally picked up as part of the Url on other GET controller methods (I have a working route that does this)
I am successfully passing the array1 from the form in my view to the controller method, but how do I also put the id onto my Url so that when the user clicks the Submit button, the controller method will pick up the ID?
What do you think is the best way to develop iphone apps on windows? What are the pros / cons of your method, and why do you use it over other options? How complex is your method in relation to other options?
