  • Last matching symbol in Regex

    - by Menda
    I couldn't find a more descriptive title, but here there is an example: import re m = re.search(r"\((?P<remixer>.+) (Remix)\)", "Title (Menda Remix)") m.group("remixer") # returns 'Menda' OK m = re.search(r"\((?P<remixer>.+) (Remix)\)", "Title (Blabla) (Menda Remix)") m.group("remixer") # returns 'Blabla) (Menda' FAIL This regex finds the first parenthesis, and I would like to match the last parenthesis for always getting 'Menda'. I've made a workaround to this using extra functions, but I would like a cleaner and a more consistent way using the same regex. Thanks a lot guys.

  • Django select max id

    - by pistacchio
    Hi, given a standard model (called Image) with an autoset 'id', how do I get the max id? So far I've tried: max_id = Image.objects.all().aggregate(Max('id')) but I get a 'id__max' Key error. Trying max_id = Image.objects.order_by('id')[0].id gives a 'argument 2 to map() must support iteration' exception Any help?

  • Read and write directly from and to compressed files in C

    - by victor
    Hi, in Java I think it is possible to cruise through jar files like they were not compressed. Is there some similar (and portable) thing in C/C++ ? I would like to import binary data into memory from a large (zipped or similar) file without decompressing to disk first and afterwards writing to disk in a compressed way. Maybe some trick with shell pipes and the zip utility?

  • How to change the coordinate origin in Flash's stage with Actionscript?

    - by Petruza
    I think I did this before but can't find the code. Flash as many other graphical frameworks use the top-left corner as the coordinate origin (0,0) because it's how the underlying memory model is by convention. But it would be really simpler for my calculations if the origin was in the center of the stage, because all the game revolves around the center and uses a lot of trigonometry, angles, etc. Is there some built-in method like Stage::setOrigin( uint, uint ); or something like that?

    - by Craig HB

They all import and work except for the one with the Konesans File system Watcher task. I installed in the setup exe for Konesans File system Watcher SQL Server 2008 on my dev pc and the production server, but still get this error: Exception from HRESULT: 0xC0010026 (Microsoft.SqlServer.DTSRuntimeWrap) Any advice?

  • passing multiple vectors to function by reference (using structure)

    - by madman
    Hi StackOverflow, Can someone tell me the correct way of passing multiple vectors to a function that can take only a single argument? (specifically for pthread_create (..) function) I tried the following but it does not seem to work :-( First, I created the following structure struct ip2 { void* obj; int dim; int n_s; vector<vector<vector<double> > > *wlist; vector<int> *nrsv; struct model *pModel; }; The threads that I have created actually needs all these parameters. Since im using pthreads_create I put all this in a structure and then passed the pointer to the structure as an argument to pthread_create (as shown). some_fxn() { //some code struct ip2 ip; ip.obj=(void*) this; ip.n_s=n_s; ip.wlist=&wlist; ip.nrsv=&nrsv; ip.pModel=pModel; ip.dim=dim; pthread_create(&callThd1[lcntr], &attr1, &Cls::Entry, (void*) &ip); } The Entry method looks something like this. void* Cls::Entry(void *ip) { struct ip2 *x; x = (struct ip2 *)ip; (reinterpret_cast<Cls1 *>(x->obj))->Run(x->dim,x->n_s, x->wlist, x->nrsv, x->pModel); } The Run method looks something like this. void Run(int dim, int n_c, vector<vector<vector<double> > > *wlist, vector<int> *nrsv, struct model* pModel ) { //some code for(int k = 0; k < n_c; ++k) { //some code end = index + nrsv[k]; //some code } I get the following error when I try to compile the program. error: no match for ‘operator+’ in ‘index + *(((std::vector<int, std::allocator<int> >*)(((unsigned int)k) * 12u)) + nrsv)’ Can someone tell me how to do it the right way.

    - by Archana R
    Hello, I want to create buttons with images and text inside. For example, i would use different images and text for buttons like 'Browse folders' and 'Import'. One of the options would be to use a template. I had a look at simliar question http://stackoverflow.com/questions/1933127/creating-an-imagetext-button-with-a-control-template But is there any way by which i can bind the source of image without using a dependency property or any other class? Thanks

    - by Ermin
    Let's say I have the following model: Person <AR def name [self.first_name,self.middle_name,self.last_name].select{|n| n.present?}.join(' ') end end How could I do a search on the virtual attribute with searchlogic, something like: Person.search.name_like 'foo' Of courese I could construct a large statement like: Person.search.first_name_like_or_last_name_like_or_... 'argh' but surely there is a more elegant way.

    We are currently hosting an ASP.NET MVC application and we wish to incorporate a turn-key customer feedback system. UserVoice will absolutely meet our needs, but we'd like to consider alternatives before moving forward. GetSatification appears to provide a similiar model. Are there any other service which we should consider as well?

  • Where do I define dependency properties shared by the detail views in a master-detail MVVM WPF scena

    - by absence
    I can think of two ways to implement dependency properties that are shared between the detail views: Store them in the master view model and add data bindings to the detail view models when they are created, and bind to them in the detail view. Don't store them in the view models at all, and use FindAncestor to bind directly to properties of the master view instead. What are the pros and cons of each, and are there other/better options?

  • OperationalError: foreign key mismatch

    - by Niek de Klein
    I have two tables that I'm filling, 'msrun' and 'feature'. 'feature' has a foreign key pointing to the 'msrun_name' column of the 'msrun' table. Inserting in the tables works fine. But when I try to delete from the 'feature' table I get the following error: pysqlite2.dbapi2.OperationalError: foreign key mismatch From the rules of foreign keys in the manual of SQLite: - The parent table does not exist, or - The parent key columns named in the foreign key constraint do not exist, or - The parent key columns named in the foreign key constraint are not the primary key of the parent table and are not subject to a unique constraint using collating sequence specified in the CREATE TABLE, or - The child table references the primary key of the parent without specifying the primary key columns and the number of primary key columns in the parent do not match the number of child key columns. I can see nothing that I'm violating. My create tables look like this: DROP TABLE IF EXISTS `msrun`; -- ----------------------------------------------------- -- Table `msrun` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `msrun` ( `msrun_name` VARCHAR(40) PRIMARY KEY NOT NULL , `description` VARCHAR(500) NOT NULL ); DROP TABLE IF EXISTS `feature`; -- ----------------------------------------------------- -- Table `feature` -- ----------------------------------------------------- CREATE TABLE IF NOT EXISTS `feature` ( `feature_id` VARCHAR(40) PRIMARY KEY NOT NULL , `intensity` DOUBLE NOT NULL , `overallquality` DOUBLE NOT NULL , `charge` INT NOT NULL , `content` VARCHAR(45) NOT NULL , `msrun_msrun_name` VARCHAR(40) NOT NULL , CONSTRAINT `fk_feature_msrun1` FOREIGN KEY (`msrun_msrun_name` ) REFERENCES `msrun` (`msrun_name` ) ON DELETE NO ACTION ON UPDATE NO ACTION); CREATE UNIQUE INDEX `id_UNIQUE` ON `feature` (`feature_id` ASC); CREATE INDEX `fk_feature_msrun1` ON `feature` (`msrun_msrun_name` ASC); As far as I can see the parent table exists, the foreign key is pointing to the right parent key, the parent key is a primary key and the foreign key specifies the primary key column. The script that produces the error: from pysqlite2 import dbapi2 as sqlite import parseFeatureXML connection = sqlite.connect('example.db') cursor = connection.cursor() cursor.execute("PRAGMA foreign_keys=ON") inputValues = ('example', 'description') cursor.execute("INSERT INTO `msrun` VALUES(?, ?)", inputValues) featureXML = parseFeatureXML.Reader('../example_scripts/example_files/input/featureXML_example.featureXML') for feature in featureXML.getSimpleFeatureInfo(): inputValues = (featureXML['id'], featureXML['intensity'], featureXML['overallquality'], featureXML['charge'], featureXML['content'], 'example') # insert the values into msrun using ? for sql injection safety cursor.execute("INSERT INTO `feature` VALUES(?,?,?,?,?,?)", inputValues) connection.commit() for feature in featureXML.getSimpleFeatureInfo(): cursor.execute("DELETE FROM `feature` WHERE feature_id = ?", (str(featureXML['id']),))
