  • Can Settings bundle use values from application's Info.plist file?

    - by delirus
    Hi, is it possible to use values from application's Info.plist file as DefaultValue value for items in Settings.bundle? For example CFBundleVersion. I've tried entering it as ${CFBundleVersion} but it didn't work. I've also tried changing DefaultValue type but with no success. Any ideas? The reasons behind are simple: CFBundleVersion is known at compile time, so I won't have to take its value from application's mainBundle and then apply that value to NSUserDefaults. Other reason is that just after installing the app, but before running it, Settings bundle values are not in-sync as the code setting NSUserDefaults did not have a chance to execute itself... so it would be boring to always remember that I have to change my Settings bundle values manually.

  • Question on SQL Grouping

    - by Lijo
    Hi Team, I am trying to achieve the following without using sub query. For a funding, I would like to select the latest Letter created date and the ‘earliest worklist created since letter created’ date for a funding. FundingId Leter (1, 1/1/2009 )(1, 5/5/2009) (1, 8/8/2009) (2, 3/3/2009) FundingId WorkList (1, 5/5/2009 ) (1, 9/9/2009) (1, 10/10/2009) (2, 2/2/2009) Expected Result - FundingId Leter WorkList (1, 8/8/2009, 9/9/2009) I wrote a query as follows. It has a bug. It will omit those FundingId for which the minimum WorkList date is less than latest Letter date (even though it has another worklist with greater than letter created date). CREATE TABLE #Funding( [Funding_ID] [int] IDENTITY(1,1) NOT NULL, [Funding_No] [int] NOT NULL, CONSTRAINT [PK_Center_Center_ID] PRIMARY KEY NONCLUSTERED ([Funding_ID] ASC) ) ON [PRIMARY] CREATE TABLE #Letter( [Letter_ID] [int] IDENTITY(1,1) NOT NULL, [Funding_ID] [int] NOT NULL, [CreatedDt] [SMALLDATETIME], CONSTRAINT [PK_Letter_Letter_ID] PRIMARY KEY NONCLUSTERED ([Letter_ID] ASC) ) ON [PRIMARY] CREATE TABLE #WorkList( [WorkList_ID] [int] IDENTITY(1,1) NOT NULL, [Funding_ID] [int] NOT NULL, [CreatedDt] [SMALLDATETIME], CONSTRAINT [PK_WorkList_WorkList_ID] PRIMARY KEY NONCLUSTERED ([WorkList_ID] ASC) ) ON [PRIMARY] SELECT F.Funding_ID, Funding_No, MAX (L.CreatedDt), MIN(W.CreatedDt) FROM #Funding F INNER JOIN #Letter L ON L.Funding_ID = F.Funding_ID LEFT OUTER JOIN #WorkList W ON W.Funding_ID = F.Funding_ID GROUP BY F.Funding_ID,Funding_No HAVING MIN(W.CreatedDt) MAX (L.CreatedDt) How can I write a correct query without using subquery? Please help Thanks Lijo

  • How do I add a property to a Javascript Object using a variable as the name?

    - by Todd R
    I'm pulling items out of the DOM with JQuery and want to set a property on an object using the id of the DOM element. For example: obj = {}; jQuery(itemsFromDom).each(function() { element = jQuery(this); name = element.attr("id"); value = element.attr("value"); //Here's the problem obj.name = value; }); If "itemsFromDom" includes an element with an id of "myId", I want "obj" to have a property named "myId". The above gives me "name". How, in javascript, do I name a property of an object using a variable?

  • SQL Server, fetching data from multiple joined tables. Why is slow?

    - by user562192
    I have problem with performance when retrieving data from SQL Server. My sql query looks something like this: SELECT table_1.id, table_1.value, table_2.id, table_2.value,..., table_20.id, table_20.value From table_1 INNER JOIN table_2 ON table_1.id = table_2.table_1_id INNER JOIN table_3 ON table_2.id = table_3.table_2_id... WHERE table_1.row_number BETWEEN 1 AND 20 So, I am fetching 20 results. This query takes about 5 seconds to execute. When I select only table_1.id, it returns results instantly. Because of that, I guess that problem is not in JOINs, it is in retrieving data from multiple tables. Any suggestions how I would speed up this query?

  • Single C++/CLI method to wrap many type specific C functions

    - by T33C
    I am wrapping a C library using C++/CLI so that the C library can be used easily from C# in a C#'ish way. Some of the functions in this library are for putting a value into a container. There are no generics in C so there exists a function per type CLIB_SetBool(BOOL value), CLIB_SetInt(int value), CLIB_SetString(char* string) and so on. To make it easier to use from C#, I have created a single Set function which takes a System::Object. I have two related questions: With my method how would you use a switch statement on the type of System::Object to call the correct CLIB_Setxxxx function. [typeid is only for unmanaged code and I can't seem to use GetType.] Is there a better way to wrap these functions like using a Generic? [I started using template specialisation but then realised that C# doesn't see templates.] Thanks.

  • Is there a way to use a dictionary or xml in the Application Settings?

    - by Shimmy
    I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings? Update I found a way, simply by editing the .settings file with the xml editor. I changed it to a custom serializable dictionary, but I get the following error when I try to access the setting-property (I set it to a serialized representation of the default value). The property 'Setting' could not be created from it's default value. Error message: There is an error in XML document (1, 41). Any ideas will be appreciated.

  • Scala's tuple unwrapping nuance

    - by Paul Milovanov
    I've noticed the following behavior in scala when trying to unwrap tuples into vals: scala> val (A, B, C) = (1, 2, 3) <console>:5: error: not found: value A val (A, B, C) = (1, 2, 3) ^ <console>:5: error: not found: value B val (A, B, C) = (1, 2, 3) ^ <console>:5: error: not found: value C val (A, B, C) = (1, 2, 3) ^ scala> val (u, v, w) = (1, 2, 3) u: Int = 1 v: Int = 2 w: Int = 3 Is that because scala's pattern matching mechanism automatically presumes that all identifiers starting with capitals within patterns are constants, or is that due to some other reason? Thanks!

  • Generating random thumbnails with PHP+FFMPEG

    - by MrGhost
    I am trying to generate thumbnails from movies using FFMPEG and the FFMPEG-PHP extension. My script works OK however takes 20 minutes just to generate 5-10 thumbnails! The script works by generating random numbers which are used as frame numbers later. All numbers generated are within the movies frame count. Can you work out why this script is taking 20 mins to finish? <?php //Dont' timeout set_time_limit(0); //Load the file (This can be any file - still takes ages) $mov = new ffmpeg_movie('1486460.mp4'); //Get the total frames within the movie $total_frames = $mov->getFrameCount(); //Loop 5 times to generate random frame times for ($i = 1; $i <= 5; ) { // Generate a number within 200 and the total number of frames. $frame = mt_rand(200,$total_frames); $getframe = $mov->getFrame($frame); // Check if the frame exists within the movie // If it does, place the frame number inside an array and break the current loop if($getframe){ $frames[$frame] = $getframe ; $i++; } } //For each frame found generate a thumbnail foreach ($frames as $key => $getframe) { $gd_image = $getframe->toGDImage(); imagejpeg($gd_image, "images/shot_".$key.'.jpeg'); imagedestroy($gd_image); echo $key.'<br/>'; } ?> The script SHOULD be generating frame numbers which are valid? Anything within START - END should be valid frame numbers? Yet the loop takes ages!

  • Postback of delimited text from javascript and parsing on server side

    - by Alt_Doru
    In my ASP.NET page, I have a Javascript object, like this: var args = new Object(); args.Data1 = document.getElementById("Data1").value; args.Data2 = document.getElementById("Data2").value; args.Data3 = document.getElementById("Data3").value; The object is populated on client side using user input data. I am passing the data to a C# method, through an Ajax request: someObj.AjaxRequest(argsData1 + "|" + argsData2 + "|" + argsData3) Finally, I need to obtain the data in my C# code: string data1 = [JS args.Data1] string data2 = [JS args.Data2] string data3 = [JS args.Data3] My question is what's the best solution for this? As i am concatenating bits of user input, I don't think it's best to use "|" as a delimiter. Also, it's not clear to me how to actually parse the data in my C# code to populate the three variables with the original data.

  • How is this input tag linking to another page?

    - by Matt
    Response.Write("<div><input type='submit' name='submit' value='Update Cart' /></div>") Response.Write("<div><input type='submit' name='submit' value='Shop More' /></div>") Response.Write("<div><input type='submit' name='submit' value='Checkout' /></div>") that is some example code from my teacher, but he hasn't answered my email in a couple days so I need some help. When you click the Update Cart button it just updates the cart page it's on, but when you click the Shop More button it links to Shop.aspx a different page, and the Checkout links to another page as well. I can't figure out how it is linking just from that code, anybody have any insights?

  • WPF/XAML - compare the "SelectedIndex" of two comboboxes (DataTrigger?)

    - by Luaca
    hello, i've got two comboboxes with the same content. the user should not be allowed to choose the same item twice. therefore the comboboxes' contents (= selectedindex?) should never be equal. my first attempt was to comapare the selectedindex with a datatrigger to show/hide a button: <DataTrigger Binding="{Binding ElementName=comboBox1, Path=SelectedIndex}" Value="{Binding ElementName=comboBox2, Path=SelectedIndex}"> <Setter Property="Visibility" Value="Hidden" /> </DataTrigger> it seems that it is not possible to use Value={Binding}. is there any other way (if possible without using a converter)? thanks in advance!

  • In Xlib, How can I animate until an event occurs?

    - by Animateur
    Hi, I've been trying to animate in a C program using Xlib and I wanna do something when an event occurs, otherwise I wanna keep animating. Here's an example code snippet of what I am doing currently: while( 1 ) { // If an event occurs, stop and do whatever is needed. // If no event occurs, skip this if statement. if ( XEventsQueued( display, QueuedAlready ) > 0 ) { XNextEvent( display, &event ) switch ( event.type ) { // Don't do anything case Expose: while ( event.xexpose.count != 0 ) break; // Do something, when a button is pressed case ButtonPress: ... break; // Do something, when a key is pressed case KeyPress: ... break; } } animate(); // Do animation step i.e. change any drawings... repaint(); // Paint again with the new changes from animation... } So basically, I wanna keep looping if the user hasn't clicked the mouse OR pressed a key in the keyboard yet. When the user presses a key OR clicks the mouse, I wanna stop and do a specific action. The problem in my above code is that, it doesnt stop whenever I do an action. If I remove the if statement, the animation blocks until an event occurs, however I do not want this. It's a simple problem, but I'm kinda new to Xlib/animations so any help would be highly appreciated. Thanks.

  • User HasOne ActiveToken, HasMany Tokens, how to setup in Rails?

    - by viatropos
    I have two simple models: class User < ActiveRecord::Base has_many :tokens # has_one doesn't work, because Token already stores # foreign id to user... # has_one :active_token, :class_name => "Token" # belongs_to doesn't work because Token belongs to # User already, and they both can't belong to each other # belongs_to :active_token, :class_name => "Token" end class Token < ActiveRecord::Base belongs_to :user end I want to say "User has_one :active_token, :class_name => 'Token'", but I can't because Token already belongs_to User. What I did instead was just manually add similar functionality to the user like so: class User < ActiveRecord::Base has_many :tokens attr_accessor :active_token after_create :save_active_token before_destroy :destroy_active_token # it belongs_to, but you can't have both belongs_to each other... def active_token return nil unless self.active_token_id @active_token ||= Token.find(self.active_token_id) end def active_token=(value) self.active_token_id = value.id @active_token = value end def save_active_token self.active_token.user = self self.active_token.save end def destroy_active_token self.active_token.destroy if self.active_token end end Is there a better way?

  • Correct CSS inheritance behavior for properties that aren't inherited?

    - by Chris
    So say we you have a CSS property that is not inherited by default. We'll call it "foo" and its default value is "black". Then we make the following html. <div id="div1" style="foo: red;"> <div id="div2"> <div id="div3" style="foo: inherit;"> </div> </div> </div> Since this property does not inherit by default, you'd think that in div2, "foo" must be "black" - the default value because it does not inherit by default. But ... in div3 should the value for "foo" inherit "black" from its parent that did not inherit foo, or should it inherit "red" from its grandparent because its parent did not specify foo? I need to know because I'm trying to implement something exactly to the spec.
