i am connect to a mysql database using this example:
http://bitdaddys.com/MySQL-ConnectorNet.html
at the top the instruction is to:
Next add reference to: MySql.Data
how do i do that?
NSXMLTypeStore is used when starting Core Data backed application by default because it's good for debugging purposes. But practice dictates that developer should use either NSBinaryStoreType, NSInMemoryStoreType or NSSQLiteStoreType store types in release builds.
How do you manage changes between debug and release builds? I believe that changing store type from NSXMLTypeStore to, say, NSBinaryStoreType in code on each release is kinda cumbersome.
I am sending push notifications from php job application to iphone. I am sending push notifications regarding new jobs. Is this possible that when user click on the view of push notification pop up , then user redirect to the particular job in the device.
I mean I wanted to know can I send any custom data with push notification like jobId,something else....so that Iphone end Can retrieve and show the particular job ?
Thanks.
Is there a common method to encode and decode arbitrary data so the encoded end result consists of numbers only - like base64_encode but without the letters?
Fictitious example:
$encoded = numbers_encode("Mary had a little lamb");
echo $encoded; // outputs e.g. 122384337422394237423 (fictitious result)
$decoded = numbers_decode("122384337422394237423");
echo $decoded; // outputs "Mary had a little lamb"
Hi,
I want to extract some kind of bmp/rgb data from jpeg files.
I had a look at libjpeg, but there seemed not to be any good documentation available.
So my questions are:
Where is documentation on libjpeg?
Can you suggest other c-based jpeg-decompression libraries?
thanks in regard
ps: I am using GNU/Linux, and c/c++
I've been struggling with this problem just like everyone else and I'm quite sure there has been more than enough posts to explain this problem. However in terms of understanding it fully, I wanted to share my thoughts and get more efficient solutions from all the great people in here related to Subset Sum problem.
I've searched it over the Internet and there is actually a lot sources but I'm really willing to re-implement an algorithm or finding my own in order to understand fully.
The key thing I'm struggling with is the efficiency considering the set size will be large. (I do not have a limit, just conceptually large). The two phases I'm trying to implement ideas on is finding two numbers that are equal to given integer T, finding three numbers and eventually K numbers. Some ideas I've though;
For the two integer part I'm thing basically sorting the array O(nlogn) and for each element in the array searching for its negative value. (i.e if the array element is 3 searching for -3). Maybe a hash table inclusion could be better, providing a O(1) indexing the element?
For the three or more integers I've found an amazing blog post;http://www.skorks.com/2011/02/algorithms-a-dropbox-challenge-and-dynamic-programming/. However even the author itself states that it is not applicable for large numbers.
So I was for 2 and 3 and more integers what ideas could be applied for the subset problem. I'm struggling with setting up a dynamic programming method that will be efficient for the large inputs as well.
Hi Guys,
Im trying to sort a column of data in a gtk tree view column non alphabetically. I cant seem to find a function in the GTK libraries that cant do such a thing
Does anyone here know of a way to do this?

I would like to get at the raw image data, as in a pointed to a byte array or something like that, of the image output from a direct3d app without actually rendering it to the monitor.
I need to do this so that I can render direct3d as a directshow source filter

I hava a data window object, in which I am fetching some attributes from the database to show it to the users. I want to make the computed fields read-only, so that the user can not modify them.
How can I make a computed field read-only?
If I need to append data (not insert) into a particular super column, what should I do?
For eg:
Consider a existing record described below
Kespace : test
columFamily: testColum
SuperColumn : testSuper
column_name : email
value : [email protected]
Here if I want to add my phone number to the super column "testSuper". What should I do?
I am trying to write data to an RTF file and set certain characters to a different color. I found out how to do it in a box but I can't figure out how to write it to a file.
i run web application on iis 6 , windows server 2003 , mysql database.
first it was working fine, but when i reconfigured the mysql server with the same password it gave me this message error when i want to enter any page in browser :
"MySql.Data.MySqlClient.MySqlException: There is no 'root'@'%' registered".
i checked the app connection it's the same, as though the app doesn't see the localhost , because "dbforge" sometimes give me this message: "connection localhost cannot be found" but when i doubleclick the connection it opens as root.
any idea to solve this problem
What are your favorite ways to encapsulate LINQ to SQL entity classes and data-context classes into business objects?
What have you found to work in a given situation?
Have you invented or taken to any specific patterns?
If I were to build a newsletter emailing system, I will need to be able to generate reports on how many emails bounced, flagged as spam, unsubscribed, read vs. unread, click through rates etc....
So how do you keep track of user activity after the email has been sent? Am I right in assuming that you CAN NOT embed javascript code into emails to monitor user activity? How else do I gather data for my reports?
I am just learning Core Data on iPhone and the tutorial I am following says to create a new file and select NSManagedObject as the template. However, in Xcode 3.2.2 it seems to be gone. Is there any way to get it back or some kind of workaround?
Thanks in advance!
is it possible to have an html form organized/named in such a way that $foo-fromArray($_POST) would actually save relational data as well?
example:
html_form_fields:
user_name
country_name
db_table_users:
id
user_name
db_table_countries:
id
country_name
update:
forgot to say i'm trying to make this with zend framework forms

I'm trying to make a page using data from the discogs.com (XML)-API. i've been parsing it with simpleXML and it's working pretty well but there is some things i'm not sure how to do.
Here is part of the XML:
<releases>
<release id="1468764" status="Accepted" type="Main">
<title>Versions</title>
<format>12", EP</format>
<label>Not On Label</label>
<year>1999</year>
</release>
<release id="72246" status="Accepted" type="Main">
<title>The M.O.F Blend</title>
<format>LP</format>
<label>Blenda Records</label>
<year>2002</year>
</release>
<release id="890064" status="Accepted" type="Main">
<title>The M.O.F Blend</title>
<format>CD</format>
<label>Blenda Records</label>
<year>2002</year>
</release>
<release id="1563561" status="Accepted" type="TrackAppearance">
<title>Ännu En Gång Vol. 3</title>
<trackinfo>Backtrack</trackinfo>
<format>Cass, Comp, Mix</format>
<label>Hemmalaget</label>
<year>2001</year>
</release>
</releases>
What i want to achieve is something similair to how discogs presents the releases: http://www.discogs.com/artist/Mics+Of+Fury where diferent versions of the same release are sorted together. (see. The M.O.F Blend in my link) This is done on discogs with having a master release that features the other releases. unfortunately this information isn't present in the API data, so i want to do the same thing by grouping the <release>-nodes with the same <title>-tags, or add a flag to the <releases> that don't have a unique <title>? any good ideas on the best way of doing this?
i also like to know if it's possible to count the <release>-nodes (child of releases) that have the same type-attribute? like in this example count the releases with the type "Main"?
maybe it's better to do this things with XMLReader or XPath?
First of all, to clarify my goal: There exist two programs written in C in our laboratory. I am working on a Proxy Server (bidirectional) for them (which will also mainpulate the data). And I want to write that proxy server in Python. It is important to know that I know close to nothing about these two programs, I only know the definition file of the packets.
Now: assuming a packet definition in one of the C++ programs reads like this:
unsigned char Packet[0x32]; // Packet[Length]
int z=0;
Packet[0]=0x00; // Spare
Packet[1]=0x32; // Length
Packet[2]=0x01; // Source
Packet[3]=0x02; // Destination
Packet[4]=0x01; // ID
Packet[5]=0x00; // Spare
for(z=0;z<=24;z+=8)
{
Packet[9-z/8]=((int)(720000+armcontrolpacket->dof0_rot*1000)/(int)pow((double)2,(double)z));
Packet[13-z/8]=((int)(720000+armcontrolpacket->dof0_speed*1000)/(int)pow((double)2,(double)z));
Packet[17-z/8]=((int)(720000+armcontrolpacket->dof1_rot*1000)/(int)pow((double)2,(double)z));
Packet[21-z/8]=((int)(720000+armcontrolpacket->dof1_speed*1000)/(int)pow((double)2,(double)z));
Packet[25-z/8]=((int)(720000+armcontrolpacket->dof2_rot*1000)/(int)pow((double)2,(double)z));
Packet[29-z/8]=((int)(720000+armcontrolpacket->dof2_speed*1000)/(int)pow((double)2,(double)z));
Packet[33-z/8]=((int)(720000+armcontrolpacket->dof3_rot*1000)/(int)pow((double)2,(double)z));
Packet[37-z/8]=((int)(720000+armcontrolpacket->dof3_speed*1000)/(int)pow((double)2,(double)z));
Packet[41-z/8]=((int)(720000+armcontrolpacket->dof4_rot*1000)/(int)pow((double)2,(double)z));
Packet[45-z/8]=((int)(720000+armcontrolpacket->dof4_speed*1000)/(int)pow((double)2,(double)z));
Packet[49-z/8]=((int)armcontrolpacket->timestamp/(int)pow(2.0,(double)z));
}
if(SendPacket(sock,(char*)&Packet,sizeof(Packet)))
return 1;
return 0;
What would be the easiest way to receive that data, convert it into a readable python format, manipulate them and send them forward to the receiver?
Hello,
I am just studying the code of Sacha Barbers MVVM framework Chinch and I saw this in the xxxViewModel.cs file:
DataService.FetchAllOrders(CurrentCustomer.CustomerId.DataValue);
DataService is a Static class. Being a junior dev I am only used to Interfaces with Data services. Why is that class static?
Or do you think he made it just for the example?
So is that a good approach?
