Hello,
I load some data from file:
GInputStream* input_stream;
GFile *file = g_file_new_for_path(file_path);
input_stream = g_file_read(file,generator_cancellable ,NULL);
g_input_stream_read(input_stream, buffer, sizeof (buffer),generator_cancellable,error);
How can i load g_input_stream_read function result to the GdkPixbufLoader object?
Thank you.
Am about to do a homework, and i need to store quite a lot of information (Dictionary) in a data structure of my choice. I heard people in my classroom saying hash-tables are the way to go. How come?
We have a database setup that consists of two parts: a static structure, and dynamic additions. For each database, the dynamic can be different, and sometimes we don't have data for all the dynamic fields. Rigt now, we check for empties by looking at the total count of records in the entire table, but we want to move to a more refined method of checking for empties if possible. Is it possible to quickly check through several hundred fields and see which ones are empty and which ones are populated?
i will need to store 3 tables of data
instead of implementing an entire database backend, i just want to store the record for these tables in application.settings
has anyone done this before?
i dont care about security
is it advisable to do it with application settings? how else would you do it?
perhaps storing a matrix in application.settings would be OK?
I'm working on a web based form builder that uses a mix of Jquery and PHP server side interaction. While the user is building the form I'm trying to determine the best method to store each of one of the form items before all the data is sent to the server. I've looked at the following methods
Javascript arrays
XML document
Send each form item to the server side to be stored in a session
I want to send the below data to default.ctp, I want to display menus in all the pages, I'm using Auth, The problem is if I'm logged in I get the Menus correctly, but if I logout, I'm getting error saying variable'$topMenu' not found.
The MenuController can be accessed only if logged in.
$this->loadModel('Menu');
$this->set('topMenu',$this->Menu->find('all'));
Any help on how to solve this?
None of the scribe examples I've seen actually mention the best way to take logs/logfiles and send them to scribe. I could configure a logrotate script that has a postrotate section that "cats" the rotated file to scribe (but then I get minutes latency at best).
The other option is to keep a "tail -f= | my_scribe_sender" and hope that the process never gets killed. However then you really can't guarantee that you're not missing/duplicating data.
I think the question is clear enough. Some of the columns in my datawarehouse table could have a relationship to a primary key. But is it good practice? It is denormalized, so it should never be deleted again (data in datawarehouse). Hope question is somewhat clear enough.
I'm searching files and returning lines that include the search text, and I'm not really sure the best way to display the information I get. Every time I get a match, I want to show, in some sort of control, the File it came from, and the whole text line. (aka streamreader.ReadLine() result). First I tried just putting it all in a read-only text box, but it doesn't have a scroll bar.
What is the best form control to help me display this data neatly?
Hi I need some sample MS SQL Employee database with data such as id, surname, name, age, adress etc. It must be quite big, I search with google, but I don't find any good sample.
Can any body help ?
Hi, is it possible to handle two data sources in the UIPickerView?
I have here a segmented control that would control the display of the picker view.
So, for example, when first segment is clicked, the picker will display person's name. Then, when second segment is clicked, picker will display place's name.
Thanks
The Core Data Programming Guide talks a lot about what not to overwrite. So the question is: What is good to overwrite?
Like I see it, I can't overwrite -init or -initWithEntity:insertIntoManagedObjectContext:
So where else would be a good overwrite point to set up some basic stuff? Or is it generally not needed to do custom initialization? Does the whole thing rely only on accessing properties which then start to do fancy things? So no custom initializations?
I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2).
I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S
Here's the code for the delegate :
- (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex
{
if ([[aTableColumn identifier] isEqualToString:@"value2"])
{
[dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]];
}
}
Any idea ?
Hi all,
I've a scenario where my java program has to continuously communicate with the database table, example my java program has to get the data of my table when new rows are added to it at runtime. There should be continuous communication between my program and database.
if the table has 10 rows initially and 2 rows are added by the user, it must detect this and return the rows.
My program shouldn't use AJAX and timers.
Please Help.

I am building a simple particle system and want to use a single array buffer of structs to manage my particles. That said, I can't find a C function that allows me to malloc() and free() from an arbitrary buffer. Here is some pseudocode to show my intent:
Particle* particles = (Particle*) malloc( sizeof(Particle) * numParticles );
Particle* firstParticle = <buffer_alloc>( particles );
initialize_particle( firstParticle );
// ... Some more stuff
if (firstParticle->life < 0)
<buffer_free>( firstParticle );
// @ program's end
free(particles);
Where <buffer_alloc> and <buffer_free> are functions that allocate and free memory chunks from arbitrary pointers (possibly with additional metadata such as buffer length, etc.). Do such functions exist and/or is there a better way to do this? Thank you!
I am doing a project on Calculix Data Visualiser. It is a civil based project. I need to show the structure of beams before applying force and the structure after the force is applied.
I need to change the color of the beams to RED where more force is applied. But i am just able to change the color for lines and not for the phase as a whole. SO pls help me out.
Hi, I'm wondering what type of threshold would work well for distinguishing features that are very small (small in the xy sense) in comparison with the full spread, if that makes sense. The graythresh() function in Matlab that uses the Otsu method doesn't work too well for my data. Otsu is a clustering method where I think the # of pixels should be similar in each class, which is not the case for me so when I employ it I get a threshold that is way too small and falls well within a lot of the background noise that remains even after filtering.
Is there any existing Python library that can validate data in Excel format? Or what kind of keyword should I use to search such an open source project? Thanks.
What are the advantages of using C++ based Classes/Objects over using legacy C Structures for managing standard Data Structures like Linked List, Stack, Tree, Queue ..etc? Let me know if the question is not clear.
I am populating data using
<select name="test">
<option value='<%=session.getAttribute("tList")%>'><%=session.getAttribute("tList") %></option>
</select>
but the values are getting display in a single row in the combo box not row wise,where i am going wrong ?
How to create a new data type which to can check/validate its schema when is created a new variable (of that type)?
By example, to validate if a string has 20 characters, I tried:
{{{
// Format: 2006-01-12T06:06:06Z
func date(str string) {
if len(str) != 20 {
fmt.Println("error")
}
}
var Date = date()
type Account struct {
domain string
username string
created Date
}
}}}
but it faills because Date is not a type.
