  • How to load image data from resource bitmap file for directshow filter ?

    - by Forrest
    I need put one bitmap image to my directshow filter. Then user can use this bitmap image and do not care where is it. First, I import this bitmap file into resource bundle, and get one IDB_BITMAP1. Then, I need to read this IDB_BITMAP1 using opencv cvLoadImage or some windows image API to load this image into buffer. So question is how to do this ? Or is that possible ? Thanks

  • How can I keep data that a user has entered in my jQuery/Ajax pop-up form?

    - by Lucas McCoy
    I have a form on a website I'm working (you can see it here) on that allows my users to give feedback. It's an jQuery/Ajax popup form: $('.contact_us').click(function(){ var boxy_content; boxy_content += "<div style=\"width:300px; height:300px \"><form id=\"feedbacked\">"; boxy_content += "<p>Subject<br /><input type=\"text\" name=\"subject\" id=\"subject\" size=\"33\" /></p><p>Your E-Mail Address:<br /><input type=\"text\" name=\"your_email\" size=\"33\" /></p><p>Comment:<br /><textarea name=\"comment\" id=\"comment\" cols=\"33\" rows=\"5\"></textarea></p><br /><input type=\"submit\" name=\"submit\" value=\"Send >>\" />"; boxy_content += "</form></div>"; // Other code here... Is there anyway I can save what the user has entered (in case they see our error message when they try to submit)?

  • Processing more than one button click at Android Widget

    - by dive
    Hi, all. I saw this topic and implement IntentService as describes, but what if I want more that one button? How can I distinguish button from each other? I'm trying to setFlags, but cannot read it at onHandleIntent() method: public static class UpdateService extends IntentService { ... @Override public void onHandleIntent(Intent intent) { ComponentName me = new ComponentName(this, ExampleProvider.class); AppWidgetManager manager = AppWidgetManager.getInstance(this); manager.updateAppWidget(me, buildUpdate(this)); } private RemoteViews buildUpdate(Context context) { RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.main_layout); Intent i = new Intent(this, ExampleProvider.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); updateViews.setOnClickPendingIntent(R.id.button_refresh, pi); i = new Intent(this, ExampleProvider.class); pi = PendingIntent.getBroadcast(context, 0, i, 0); updateViews.setOnClickPendingIntent(R.id.button_about, pi); return updateViews; } } At this little piece of code I have two PendingIntent linked with setOnClickPendingIntent, can I distinguish this intent for different actions and processing? Thanks for help

  • javascript: how to delay submitting data when several checkboxes clicked in short time interval?

    - by ~knb
    I have an array of checkboxes in a complex dynamic-html form. Whenever a user clicks one checkbox, a fairly expensive query is generated and submitted to a remote server. I want to delay this submit action depending on the users next action. If the user clicks several checkboxes quickly, all of the first clicks should be discarded, only the last one is processed and eventually submitted after 1 second or so. maybe this is a common problem but I have never worked with timeouts before.

  • How to remove EXIF data without recompressing the JPEG?

    - by Denilson Sá
    I want to remove the EXIF information (including thumbnail, metadata, camera info... everything!) from JPEG files, but I don't want to recompress it, as recompressing the JPEG will degrade the quality, as well as usually increasing the file size. I'm looking for a Unix/Linux solution, even better if using the command-line. If possible, using ImageMagick (convert tool). If that's not possible, a small Python, Perl, PHP (or other common language on Linux) script would be ok. There is a similar question, but related to .net.

  • is it better to test if a function is needed inside or outside of it?

    - by b0x0rz
    what is the best practice? call a function then return if you test for something, or test for something then call? i prefer the test inside of function because it makes an easier viewing of what functions are called. for example: protected void Application_BeginRequest(object sender, EventArgs e) { this.FixURLCosmetics(); } and private void FixURLCosmetics() { HttpContext context = HttpContext.Current; if (!context.Request.HttpMethod.ToString().Equals("GET", StringComparison.OrdinalIgnoreCase)) { // if not a GET method cancel url cosmetics return; }; string url = context.Request.RawUrl.ToString(); bool doRedirect = false; // remove > default.aspx if (url.EndsWith("/default.aspx", StringComparison.OrdinalIgnoreCase)) { url = url.Substring(0, url.Length - 12); doRedirect = true; } // remove > www if (url.Contains("//www")) { url = url.Replace("//www", "//"); doRedirect = true; } // redirect if necessary if (doRedirect) { context.Response.Redirect(url); } } is this good: if (!context.Request.HttpMethod.ToString().Equals("GET", StringComparison.OrdinalIgnoreCase)) { // if not a GET method cancel url cosmetics return; }; or should that test be done in Application_BeginRequest? what is better? thnx

  • How can I handle multiple views of a data object? Which design pattern is acceptable?

    - by tranquil.byte
    I have a person object. class Person { private $name; ... } I need to be able to change how they are displayed on the front-end ( visitors have control ). They can choose list view, grid view, photo view for example. class PersonDisplay { public function displayList() { // Query database // Output html to display in list mode } public function displayPhoto() { // Query database // Output html to display in photo mode } } Is this an acceptable way to handle the presentation of the items on the front-end or is there a specific design pattern I should be researching to help me with this task? Does anyone have any suggestions or ideas where this could go wrong or if this could potentially make maintenance a nightmare? The Person object was just an example very similiar to what I am using.

  • Need a good way to store data in a DB from a table on a webpage that can have N columns.

    - by Abe Miessler
    Users need to be able to add a specific type of column to an otherwise static table on my web page and then save the information they enter in there to the database. I've been told that in reality they will almost never go over 5 columns but I would rather support N. The columns will all be of the same datatype. My first thought was to have an XML column with the values from all added columns in there but I was curious if anyone else had come up with a better solution. Suggestions?

  • Parse filename, insert to SQL

    - by jakesankey
    Thanks to Code Poet, I am now working off of this code to parse all .txt files in a directory and store them in a database. I need a bit more help though... The file names are R303717COMP_148A2075_20100520.txt (the middle section is unique per file). I would like to add something to code so that it can parse out the R303717COMP and put that in the left column of the database such as: (this is not the only R number we have) R303717COMP data data data R303717COMP data data data R303717COMP data data data etc Lastly, I would like to have it store each full file name into another table that gets checked so that it doesn't get processed twice.. Any Help is appreciated. using System; using System.Data; using System.Data.SQLite; using System.IO; namespace CSVImport { internal class Program { private static void Main(string[] args) { using (SQLiteConnection con = new SQLiteConnection("data source=data.db3")) { if (!File.Exists("data.db3")) { con.Open(); using (SQLiteCommand cmd = con.CreateCommand()) { cmd.CommandText = @" CREATE TABLE [Import] ( [RowId] integer PRIMARY KEY AUTOINCREMENT NOT NULL, [FeatType] varchar, [FeatName] varchar, [Value] varchar, [Actual] decimal, [Nominal] decimal, [Dev] decimal, [TolMin] decimal, [TolPlus] decimal, [OutOfTol] decimal, [Comment] nvarchar);"; cmd.ExecuteNonQuery(); } con.Close(); } con.Open(); using (SQLiteCommand insertCommand = con.CreateCommand()) { insertCommand.CommandText = @" INSERT INTO Import (FeatType, FeatName, Value, Actual, Nominal, Dev, TolMin, TolPlus, OutOfTol, Comment) VALUES (@FeatType, @FeatName, @Value, @Actual, @Nominal, @Dev, @TolMin, @TolPlus, @OutOfTol, @Comment);"; insertCommand.Parameters.Add(new SQLiteParameter("@FeatType", DbType.String)); insertCommand.Parameters.Add(new SQLiteParameter("@FeatName", DbType.String)); insertCommand.Parameters.Add(new SQLiteParameter("@Value", DbType.String)); insertCommand.Parameters.Add(new SQLiteParameter("@Actual", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@Nominal", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@Dev", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@TolMin", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@TolPlus", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@OutOfTol", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@Comment", DbType.String)); string[] files = Directory.GetFiles(Environment.CurrentDirectory, "TextFile*.*"); foreach (string file in files) { string[] lines = File.ReadAllLines(file); bool parse = false; foreach (string tmpLine in lines) { string line = tmpLine.Trim(); if (!parse && line.StartsWith("Feat.

  • iPhone: Create a single UIView from multiple clicks

    - by Cuzog
    I'm making a partial overlay modal in my app with the code from “Semi-Modal (Transparent) Dialogs on the iPhone” at ramin.firoozye.com. In doing so, the button that calls the modal is still visible and clickable. I will hide this button when the modal spawns, but I want to be sure if the user clicks very quickly twice, a new modal doesn't come up for each click. What is the best way to check that the modal doesn't already exist when calling it from the button click? You can download the test project here. For those that don't have xcode, the relevant functions are below: I call forth the modal on button click with this: - (IBAction)displayModal:(id)sender { ModalViewController *modalController = [[ModalViewController alloc] initWithNibName:@"ModalViewController" bundle:nil]; modalController.view.frame = CGRectOffset(modalController.view.frame, 0, 230); [self showModal:modalController.view]; } Then use this function to animate the custom modal over the current view: - (void)showModal:(UIView*) modalView { UIWindow* mainWindow = (((TestAppDelegate*) [UIApplication sharedApplication].delegate).window); CGPoint middleCenter = modalView.center; CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); modalView.center = offScreenCenter; // we start off-screen [mainWindow addSubview:modalView]; // Show it with a transition effect [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; // animation duration in seconds modalView.center = middleCenter; [UIView commitAnimations]; } Then I dismiss the modal on button click with this: - (IBAction)dismissModal:(id)sender { [self hideModal:self.view]; } And then use these functions to animate the modal offscreen and clean itself up: - (void)hideModal:(UIView*) modalView { CGSize offSize = [UIScreen mainScreen].bounds.size; CGPoint offScreenCenter = CGPointMake(offSize.width / 2.0, offSize.height * 1.5); [UIView beginAnimations:nil context:modalView]; [UIView setAnimationDuration:0.7]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(hideModalEnded:finished:context:)]; modalView.center = offScreenCenter; [UIView commitAnimations]; } - (void)hideModalEnded:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { UIView* modalView = (UIView *)context; [modalView removeFromSuperview]; [self release]; } Any help is greatly appreciated!

  • Passing an array of data to a private function in CodeIgniter/PHP? [facepalm]

    - by Jack Webb-Heller
    So I thought this should be easy, but, I'm n00bing out here and failing epicly (as they say on teh interwebz). So here's my code: function xy() { $array['var1'] = x; $array['var2'] = y; echo $this->_z; } function _z($array) { $xy = $x.$y; return $xy; } So, why doesn't that seemingly simple code work? I know with views you can pass arrays and the variables are accessible in the views with just their array title, but, why doesn't it work in this case? Jack

  • Codebase for making a Flash-based interactive map with SVG vector data?

    - by Mike
    I'm looking for a way to take SVG path info (basically a string of coordinates) and dynamically draw it with Actionscript. Icing on the cake would be if those shapes could detect mouse events to trigger JS and dynamically change their appearance (fill, stroke, etc...). I'm currently trying something similar to this (http://raphaeljs.com/australia.html) using SVG but it's just too slow in IE. I've also tried Google's SVG Web (http://code.google.com/p/svgweb/) which basically does exactly what I'm looking for (it converts SVG to Flash in IE) but again, it's sloooooow - which is why I'm considering doing the whole shebang in Flash. Anyone know of some links to point me in the right direction?

  • Any strategies for assessing the trade-off between CPU loss and memory gain from compression of data

    - by indiehacker
    Are very large TextProperties a burden? Should they be compressed? Say I have a information stored in 2 attributes of type TextProperty in my datastore entities. The strings are always the same length of 65,000 characters and have lots of repeating integers, a sample appearing as follows: entity.pixel_idx = 0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1,5,5,5,5,5,5,5,5,5,5,5,5....etc. entity.pixel_color = 2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,1,1,1,1,1,1,1,1,1,1,1,1,...etc. So these above could also be represented using much less storage memory by compressing say using only each integer and the length of its series ( '0,8' for '0,0,0,0,0,0,0,0') but then its takes time and CPU to compress and decompress? Any general ideas? Are there some tricks for testing different attempts to the problem?

Examples of other tables in the database: Articles, Products, Supplies Here is an example of my code to view an Article Table from the database: //USING LINQ-SQL CONTEXT DATABASE public ActionResult ArticlePage() { tinypeas_db_contextDataContext context = HttpContext.Application["context"] as tinypeas_db_contextDataContext; try { return View(context.Articles); } catch { return Json(false, JsonRequestBehavior.AllowGet); } } How would I modify this method to dynamically pass any table to the view? Or should I be using something else other than Linq-to-SQL

  • MySQL query puzzle - finding what WOULD have been the most recent date

    - by Hank
    I've looked all over and haven't yet found an intelligent way to handle this, though I feel sure one is possible: One table of historical data has quarterly information: CREATE TABLE Quarterly ( unique_ID INT UNSIGNED NOT NULL, date_posted DATE NOT NULL, datasource TINYINT UNSIGNED NOT NULL, data FLOAT NOT NULL, PRIMARY KEY (unique_ID)); Another table of historical data (which is very large) contains daily information: CREATE TABLE Daily ( unique_ID INT UNSIGNED NOT NULL, date_posted DATE NOT NULL, datasource TINYINT UNSIGNED NOT NULL, data FLOAT NOT NULL, qtr_ID INT UNSIGNED, PRIMARY KEY (unique_ID)); The qtr_ID field is not part of the feed of daily data that populated the database - instead, I need to retroactively populate the qtr_ID field in the Daily table with the Quarterly.unique_ID row ID, using what would have been the most recent quarterly data on that Daily.date_posted for that data source. For example, if the quarterly data is 101 2009-03-31 1 4.5 102 2009-06-30 1 4.4 103 2009-03-31 2 7.6 104 2009-06-30 2 7.7 105 2009-09-30 1 4.7 and the daily data is 1001 2009-07-14 1 3.5 ?? 1002 2009-07-15 1 3.4 && 1003 2009-07-14 2 2.3 ^^ then we would want the ?? qtr_ID field to be assigned '102' as the most recent quarter for that data source on that date, and && would also be '102', and ^^ would be '104'. The challenges include that both tables (particularly the daily table) are actually very large, they can't be normalized to get rid of the repetitive dates or otherwise optimized, and for certain daily entries there is no preceding quarterly entry. I have tried a variety of joins, using datediff (where the challenge is finding the minimum value of datediff greater than zero), and other attempts but nothing is working for me - usually my syntax is breaking somewhere. Any ideas welcome - I'll execute any basic ideas or concepts and report back.

  • XML and .NET: How to replace specific node with many other ones loaded from raw xml data

    - by Entrase
    Let's suppose we have an element like this one in the main xml file: <group name="gr1" filename="groups/gr1.xml"/>. The second file gr1.xml contains something like this: <item name="i1">Item one</item> <item name="i2">Item two</item> <item name="i3">Item three</item> Note that there is no XML declaration in gr1.xml, just plain items without single parent node. So… Which is the best way to replace <group/> with its <item/>s? I have already tried some things like manual enclosing of gr1.xml content into a single node with XML declaration and loading it into XmlDocument, but it doesn't look like a good solution.
