• SQLITE basic syntax

  - by Doori Bar

  I seem to misunderstand a basic syntax, why this sample works: sqlite3_prepare_v2(db, "insert into test values('boo','boo',0);", strlen(querystring)+1 , &stmt, NULL); if ((rc = sqlite3_step(stmt)) != SQLITE_DONE) fprintf(stderr, "Error: sqlite3_step() %d. Error Message %s;\n",rc,sqlite3_errmsg(db)); But when I try this query: "insert into test(strtest) values('boo');" I get an error: Error: sqlite3_step() 19. Error Message constraint failed; What am I missing? table test is: "create table test (blobtest BLOB(4) NOT NULL, strtest VARCHAR NOT NULL, inttest INTEGER NOT NULL );" Thanks, Doori Bar

• Deleting Duplicates in MySQL

  - by elmaso

  Query was this: CREATE TABLE `query` ( `id` int(11) NOT NULL auto_increment, `searchquery` varchar(255) NOT NULL default '', `datetime` int(11) NOT NULL default '0', PRIMARY KEY (`id`) ) ENGINE=MyISAM first I want to drop the table with: ALTER TABLE `querynew` DROP `id` and then delete the double entries.. I tried it with: INSERT INTO `querynew` SELECT DISTINCT * FROM `query` but with no success.. :( and with ALTER TABLE query ADD UNIQUE ( searchquery ) - is it possible to save the queries only one time?

But for example, if I modify that queue in any way.. like.. assign it to a different queue.. Queue<double> qdub1; Queue<double> qdub2; qdub1.enqueue(0; qdub2 = qdub1; cout << qdub2 << endl; It will give me weird values for 0 like.. 7.86914e-316. Help on this would be much appreciated!

• Threading.Timer invokes asynchronously many methods

  - by Dimitar

  Hi guys! Please help! I call a threading.timer from global.asax which invokes many methods each of which gets data from different services and writes it to files. My question is how do i make the methods to be invoked on a regular basis let's say 5 mins? What i do is: in Global.asax I declare a timer protected void Application_Start() { TimerCallback timerDelegate = new TimerCallback(myMainMethod); Timer mytimer = new Timer(timerDelegate, null, 0, 300000); Application.Add("timer", mytimer); } the declaration of myMainMethod looks like this: public static void myMainMethod(object obj) { MyDelegateType d1 = new MyDelegateType(getandwriteServiceData1); d1.BeginInvoke(null, null); MyDelegateType d2 = new MyDelegateType(getandwriteServiceData2); d2.BeginInvoke(null, null); } this approach works fine but it invokes myMainMethod every 5 mins. What I need is the method to be invoked 5 mins after all the data is retreaved and written to files on the server. How do I do that?

• CakePHP. How can i make a model test in a table with another primary key?

  - by Marcelo

  I have this table CREATE TABLE myexamples.problems ( id INT, name VARCHAR(45) NULL , pk_id INT AUTO_INCREMENT PRIMARY KEY ); But when I try test a model in cakephp, it fails because the table has two autoincrement attributes. The following query CREATE TABLE `test_suite_problems` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(45) DEFAULT NULL, `pk_id` int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (`pk_id`) ) DEFAULT CHARSET=latin1, COLLATE=latin1_swedish_ci, ENGINE=InnoDB; raise this error: "1075: Incorrect table definition; there can be only one auto column and it must be defined as a key" I have in the model class <?php class Problem extends AppModel { var $name = 'Problem'; var $displayField = 'name'; var $primaryKey='problems'; } ?> But I don't know how to make the field ID not having an autoincrement attribute, and I can't change the table structure.

• django: How to make one form from multiple models containing foreignkeys

  - by Tim

  I am trying to make a form on one page that uses multiple models. The models reference each other. I am having trouble getting the form to validate because I cant figure out how to get the id of two of the models used in the form into the form to validate it. I used a hidden key in the template but I cant figure out how to make it work in the views My code is below: views: def the_view(request, a_id,): if request.method == 'POST': b_form= BForm(request.POST) c_form =CForm(request.POST) print "post" if b_form.is_valid() and c_form.is_valid(): print "valid" b_form.save() c_form.save() return HttpResponseRedirect(reverse('myproj.pro.views.this_page')) else: b_form= BForm() c_form = CForm() b_ide = B.objects.get(pk=request.b_id) id_of_a = A.objects.get(pk=a_id) return render_to_response('myproj/a/c.html', {'b_form':b_form, 'c_form':c_form, 'id_of_a':id_of_a, 'b_id':b_ide }) models class A(models.Model): name = models.CharField(max_length=256, null=True, blank=True) classe = models.CharField(max_length=256, null=True, blank=True) def __str__(self): return self.name class B(models.Model): aid = models.ForeignKey(A, null=True, blank=True) number = models.IntegerField(max_length=1000) other_number = models.IntegerField(max_length=1000) class C(models.Model): bid = models.ForeignKey(B, null=False, blank=False) field_name = models.CharField(max_length=15) field_value = models.CharField(max_length=256, null=True, blank=True) forms from mappamundi.mappa.models import A, B, C class BForm(forms.ModelForm): class Meta: model = B exclude = ('aid',) class CForm(forms.ModelForm): class Meta: model = C exclude = ('bid',) B has a foreign key reference to A, C has a foreign key reference to B. Since the models are related, I want to have the forms for them on one page, 1 submit button. Since I need to fill out fields for the forms for B and C & I dont want to select the id of B from a drop down list, I need to somehow get the id of the B form into the form so it will validate. I have a hidden field in the template, I just need to figure how to do it in the views

• Reading in bytes produced by PHP script in Java to create a bitmap

  - by Kareem

  I'm having trouble getting the compressed jpeg image (stored as a blob in my database). here is the snippet of code I use to output the image that I have in my database: if($row = mysql_fetch_array($sql)) { $size = $row['image_size']; $image = $row['image']; if($image == null){ echo "no image!"; } else { header('Content-Type: content/data'); header("Content-length: $size"); echo $image; } } here is the code that I use to read in from the server: URL sizeUrl = new URL(MYURL); URLConnection sizeConn = sizeUrl.openConnection(); // Get The Response BufferedReader sizeRd = new BufferedReader(new InputStreamReader(sizeConn.getInputStream())); String line = ""; while(line.equals("")){ line = sizeRd.readLine(); } int image_size = Integer.parseInt(line); if(image_size == 0){ return null; } URL imageUrl = new URL(MYIMAGEURL); URLConnection imageConn = imageUrl.openConnection(); // Get The Response InputStream imageRd = imageConn.getInputStream(); byte[] bytedata = new byte[image_size]; int read = imageRd.read(bytedata, 0, image_size); Log.e("IMAGEDOWNLOADER", "read "+ read + " amount of bytes"); Log.e("IMAGEDOWNLOADER", "byte data has length " + bytedata.length); Bitmap theImage = BitmapFactory.decodeByteArray(bytedata, 0, image_size); if(theImage == null){ Log.e("IMAGEDOWNLOADER", "the bitmap is null"); } return theImage; My logging shows that everything has the right length, yet theImage is always null. I'm thinking it has to do with my content type. Or maybe the way I'm uploading?

• Strange behaviour with PHP/Pear HTML_Quickform and Firfox 3.6

  - by chessweb

  I am using PHP/Pear HTMLQuickForm and HTMLQuickForm_Controller to do some stuff with HTML-forms. Then I noticed that certain phone numbers would not be displayed even though the data had been loaded correctly. I boiled it down to the following rather strange phenomenons that have me completely baffled: $this->addElement('static', null, 'Telefon:', '04556-8978765'); will just show "Telefon:" in Firefox 3.6. In IE8 I see "Telefon: 04556-8978765" as expected. $this->addElement('static', null, 'Telefon:', '904556-8978765'); displays just "Telefon: 9" in Firefox 3.6 and correctly "Telefon: 904556-8978765" in IE8. On the other hand $this->addElement('static', null, 'Telefon:', '099828-67776554'); shows "Telefon: 099828-67776554" in both browsers. So my question is this: What is so special about the string 04556-8978765 that Firefox 3.6 refuses to render it? And it gets even weirder: The string 0208-23345 and 02232-12345 have the same problem, but when I prefix them with any other character, then unlike 04556-8978765 they are displayed alright. And it is not as if the missing strings are not rendered at all. On page reload I see them for a short time and then they disappear for good. Now try to guess the result of $this->addElement('static', null, 'Telefon:', '04556-8978765'); $this->addElement('static', null, 'Telefon:', '04556-8978765'); Right, it is not Telefon: 04556-8978765 Telefon: 04556-8978765 as expected, but rather Telefon: Telefon: 04556-8978765 Can anybody make any sense of this?

• How to use SMS content provider? Where are the docs?

  - by Mark

  Hi, I'd like to be able to read the system's SMS content provider. Basically I wanted to make an SMS messaging app, but it would only be useful if I could see past threads etc. It seems like there's a content provider for this, but I can't find documentation for it - anyone know where that is? Thanks -------- edit ----------- Ok I found a way to get the sms inbox provider, and I just dumped all the column names in that provider, looks like this: Uri uriSms = Uri.parse("content://sms/inbox"); Cursor c = context.getContentResolver().query(uriSms, null,null,null,null); // column names for above provider: 0: _id 1: thread_id 2: address 3: person 4: date 5: protocol 6: read 7: status 8: type 9: reply_path_present 10: subject 11: body 12: service_center 13: locked I'm just piecing this together from random threads I find around the net, I'm really wondering where this is all documented (if at all)? Thanks again

• c++ dynamic_cast error handling

  - by Nazgob

  Is there any good practice related to dynamic_cast error handling (except not using it when you don't have to)? I'm wondering how should I go about NULL and bad_cast it can throw. Should I check for both? And if I catch bad_cast or detect NULL I probably can't recover anyway... For now, I'm using assert to check if dynamic_cast returned not NULL value. Would you accept this solution on a code review?

• Strategy to structure a search index in a relational database

  - by neilc

  I am interested in suggestions for building an efficient and robust structure for indexing products in a new database I am building (i'm using MySql) When a product is entered through the form there are three parts I am interested in indexing for searching purposes. The product title The product description Tags The most important is title, followed by tags, followed by the description. I was thinking of using the following structure CREATE TABLE `searchindex` ( `id` INT NOT NULL , `word` VARCHAR( 255 ) NOT NULL , `weighting` INT NOT NULL , `product_id` INT NOT NULL , PRIMARY KEY ( `id` ) ) Then each time a product is created I would split apart the title, description and tags (removing common words) and award them a weighting. Then it is trivial to select out the words and corresponding products and order them by weighting. Is there a better way to do this? I would be worried that this strategy would slow down over time and as the database filled up.

• SDL_BlitSurface() not displaying image?

  - by Christian Gonzalez

  So I'm trying to display a simply image with the SDL library, but when I use the function SDL_BlitSurface() nothing happens, and all I get is a black screen. I should also note that I have the .bmp file, the source, and the executable file all in the same directory. //SDL Header #include "SDL/SDL.h" int main(int argc, char* args[]) { //Starts SDL SDL_Init(SDL_INIT_EVERYTHING); //SDL Surfaces are images that are going to be displayed. SDL_Surface* Hello = NULL; SDL_Surface* Screen = NULL; //Sets the size of the window (Length, Height, Color(bits), Sets the Surface in Software Memory) Screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE); //Loads a .bmp image Hello = SDL_LoadBMP("Hello.bmp"); //Applies the loaded image to the screen SDL_BlitSurface(Hello, NULL, Screen, NULL); //Update Screen SDL_Flip(Screen); //Pause SDL_Delay(2000); //Deletes the loaded image from memory SDL_FreeSurface(Hello); //Quits SDL SDL_Quit(); return 0; }

• [Android SDK] Text-To-Speech addSpeech not working properly

  - by arcoraven

  Hi, I'm trying to get my Android app to play a .wav file recording of the word "Spinach Salad" whenever it sees that phrase being spoken by TTS. Here's the relevant code: spinach_salad.wav is located in /res/raw prodName = "Spinach Salad" mTts.addSpeech(prodName, "com.example.textextractor", R.raw.spinach_salad); ...and later in the code: mTts.speak("blah blah blah " + prodName, TextToSpeech.QUEUE_ADD, null); I've also tried: mTts.speak("blah blah blah Spinach Salad", TextToSpeech.QUEUE_ADD, null); and mTts.speak("blah blah blah", TextToSpeech.QUEUE_ADD, null); mTts.speak(productName_str, TextToSpeech.QUEUE_ADD, null); In both cases, I'm just hearing the TTS synthesized audio, rather than my custom .wav file. (On a related note, the last chunk of code sometimes speaks out of order, saying the second line before the first).

• Convert InputStream to String with encoding given in stream data

  - by Quentin

  Hi, My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document. From this InputStream, I want to have all document in a String. To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding. It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error. Any idea, how to do it ? public static String streamToString(final InputStream is) { String result = null; if (is != null) { BufferedInputStream bis = new BufferedInputStream(is); bis.mark(Integer.MAX_VALUE); final StringBuilder stringBuilder = new StringBuilder(); try { // stream reader that handle encoding final InputStreamReader readerForEncoding = new InputStreamReader(bis, "UTF-8"); final BufferedReader bufferedReaderForEncoding = new BufferedReader(readerForEncoding); String encoding = extractEncodingFromStream(bufferedReaderForEncoding); if (encoding == null) { encoding = DEFAULT_ENCODING; } // stream reader that handle encoding bis.reset(); final InputStreamReader readerForContent = new InputStreamReader(bis, encoding); final BufferedReader bufferedReaderForContent = new BufferedReader(readerForContent); String line = bufferedReaderForContent.readLine(); while (line != null) { stringBuilder.append(line); line = bufferedReaderForContent.readLine(); } bufferedReaderForContent.close(); bufferedReaderForEncoding.close(); } catch (IOException e) { // reset string builder stringBuilder.delete(0, stringBuilder.length()); } result = stringBuilder.toString(); }else { result = null; } return result; } Regards, Quentin

• Change ListView background - strage behaviour

  - by Beasly

  Hi again, I have a problem with changing the background of a view in a ListView. What I need: Change the background image of a row onClick() What actually happens: The background gets changed (selected) after pressing e.g. the first entry. But after scrolling down the 8th entry is selected too. Scroll back to the top the first isn't selected anymore. The second entry is selected now. Continue scrolling and it continues jumping... What i'm dong in the Code: I have channels, and onClick() I toggle an attribute of channel boolean selected and then I change the background. I'm doing this only onClick() thats why I don't get why it's actuelly happening on other entries too. One thing I notices is: It seems to be only the "drawing"-part because the item which get selected "by it self" has still the selected value on false I think it seems to have something to do with the reuse of the views in the custom ListAdapters getView(...) Code of onClick() in ListActivity: @Override protected ViewHolder createHolder(View v) { // createHolder will be called only as long, as the ListView is not // filled TextView title = (TextView) v .findViewById(R.id.tv_title_channel_list_adapter); TextView content = (TextView) v .findViewById(R.id.tv_content_channel_list_adapter); ImageView icon = (ImageView) v .findViewById(R.id.icon_channel_list_adapter); if (title == null || content == null || icon == null) { Log.e("ERROR on findViewById", "Couldn't find Title, Content or Icon"); } ViewHolder mvh = new MyViewHolder(title, content, icon); // We make the views become clickable // so, it is not necessary to use the android:clickable attribute in // XML v.setOnClickListener(new ChannelListAdapter.OnClickListener(mvh) { public void onClick(View v, ViewHolder viewHolder) { // we toggle the enabled state and also switch the the // background MyViewHolder mvh = (MyViewHolder) viewHolder; Channel ch = (Channel) mvh.data; ch.setSelected(!ch.getSelected()); // toggle if (ch.getSelected()) { v.setBackgroundResource(R.drawable.row_blue_selected); } else { v.setBackgroundResource(R.drawable.row_blue); } // TESTING Log.d("onClick() Channel", "onClick() Channel: " + ch.getTitle() + " selected: " + ch.getSelected()); } }); return mvh; } Code of getView(...): @Override public View getView(int position, View view, ViewGroup parent) { ViewHolder holder; // When view is not null, we can reuse it directly, there is no need // to reinflate it. // We only inflate a new View when the view supplied by ListView is // null. if (view == null) { view = mInflater.inflate(mViewId, null); // call own implementation holder = createHolder(view); // TEST // we set the holder as tag view.setTag(holder); } else { // get holder back...much faster than inflate holder = (ViewHolder) view.getTag(); } // we must update the object's reference holder.data = getItem(position); // call the own implementation bindHolder(holder); return view; } I really would appreciate any idea how to solve this! :) If more information is needed please tell me. Thanks in advance!

• Rails Habtm with a field

  - by moshimoshi

  Hello, Is that possible to have a field in a has and belongs to many table? Just like favorite: create_table :messages_users, :id => false, :force => true do |t| t.integer :message_id, :null => false t.integer :user_id, :null => false t.boolean :favorite, :null => false t.timestamps end I saw timestamps works well, thanks to ActiveRecord. But when I try to add favorite into the table and then I try: Message.first.users << User.first Then I get this error message: ActiveRecord::StatementInvalid: SQLite3::SQLException: messages_users.favorite may not be NULL: INSERT INTO "messages_users" ("created_at", "message_id", "updated_at", "user_id") VALUES ('''2010-05-27 06:07 :50.721512''', 1, '''2010-05-27 06:07:50.721512''', 1) I would like to use a habtm, I don't like has_many foo though bar association :) Is that possible? Thanks a lot.

• getline() sets failbit and skips last line

  - by Thanatos

  I'm using std::getline() to enumerate through the lines in a file, and it's mostly working. It's left me curious however - std::getline() is skipping the very last line in my file, but only if it's blank. Using this minimal example: #include <iostream> #include <string> int main() { std::string line; while(std::getline(std::cin, line)) std::cout << "Line: “" << line << "”\n"; return 0; } If I feed it this: Line A Line B Line C I get those lines back at me. But this: Line A Line B Line C [* line is present but blank, ie, the file end is: "...B\nLine C\n" *] (I unfortunately can't have a blank line in SO's little code box thing...) So, first file has three lines ( ["Line A", "Line B", "Line C"] ), second file has four ( ["Line A", "Line B", "Line C", ""] ) This to me seems wrong - I have a four line file, and enumerating it with getline() leaves me with 3. What's really got me scratching my head is that this is exactly what the standard says it should do. (21.3.7.9) Even Python has similar behaviour (but it gives me the newlines too - C++ chops them off.) Is this some weird thing where C++ is expected lines to be terminated, and not separated by '\n', and I'm feeding it differently? Edit Clearly, I need to expand a bit here. I've met up with two philosophies of determining what a "line" in a file is: Lines are terminated by newlines - Dominant in systems such as Linux, and editors like vim. Possible to have a slightly "odd" file by not having a final '\n' (a "noeol" in vim). Impossible to have a blank line at the end of a file. Lines are separated by newlines - Dominant in just about every Windows editor I've ever come across. Every file is valid, and it's possible to have the last line be blank. Of course, YMMV as to what a newline is. I've always treated these as two completely different schools of thought. One earlier point I tried to make was to ask if the C++ standard was explicitly or merely implicitly following the first. (Curiously, where is Mac? terminated or separated?)
