  • WPF Standard Commands - Where's Exit?

    - by Andrew Shepherd
    I'm creating a standard menu in my WPF application. I know that I can create custom commands, but I know there are also a bunch of standard commands to bind to. For example, to open a file I should bind to ApplicationCommands.Open, to close a file I should bind to ApplicationCommands.Close. There's also a large number of EditCommands, ComponentCommands or NavigationCommands. There doesn't seem to be an "Exit" command. I would have expected there to be ApplicationCommands.Exit. What should I bind to the "Exit" menu item? To create a custom command for something this generic just seems wrong.

  • Is there a way to get different sizes of the Windows system icons in .NET?

    - by Andrew Watt
    In particular I'd like to be able to get the small (16 x 16) icons at runtime. I tried this: new Icon(SystemIcons.Error, SystemInformation.SmallIconSize) Which supposedly "attempts to find a version of the icon that matches the requested size", but it's still giving me a 32 x 32 icon. I also tried: Size iconSize = SystemInformation.SmallIconSize; Bitmap bitmap = new Bitmap(iconSize.Width, iconSize.Height); using (Graphics g = Graphics.FromImage(bitmap)) { g.DrawIcon(SystemIcons.Error, new Rectangle(Point.Empty, iconSize)); } But that just scales the 32 x 32 icon down into an ugly 16 x 16. I've considered just pulling icons out of the VS Image Library, but I really want them to vary dynamically with the OS (XP icons on XP, Vista icons on Vista, etc.). I'm willing to P/Invoke if that's what it takes.

  • How do I keep existing values from shifting to the right when entering keypresses into a jQuery Mask

    - by Andrew
    I have a text box I'm using as a timer display "hh:mm:ss" When I select the box and press a number, it inserts the number at the cursor location, but instead of replacing the value at that position, it shifts all existing values over. For example, the timer text box reads "01:00:35" and I replace the first minute position with 1, the timer text box will then read "01:10:03." Anybody know how to force the text box to replace, instead of insert, at the cursor position? I've tried intercepting onKeyPress, doing the replace manually, rewriting the entire timer text, and then returning false. But, that doesn't worked with a jQuery masked input, because my function runs first.

  • When to use CouchDB vs RDBMS

    - by Andrew Whitehouse
    I am looking at CouchDB, which has a number of appealing features over relational databases including: intuitive REST/HTTP interface easy replication data stored as documents, rather than normalised tables I appreciate that this is not a mature product so should be adopted with caution, but am wondering whether it is actually a viable replacement for an RDBMS (in spite of the intro page saying otherwise - http://couchdb.apache.org/docs/intro.html). Under what circumstances would CouchDB be a better choice of database than an RDBMS (e.g. MySQL), e.g. in terms of scalability, design + development time, reliability and maintenance. Are there still cases where an RDBMS is still clearly the right choice? Is this an either-or choice, or is a hybrid solution more likely to emerge as best practice?

  • Trouble with detecting gestures over ListView

    - by Andrew
    I have an Activity that contains a ViewFlipper. The ViewFlipper includes 2 layouts, both of which are essentially just ListViews. So the idea here is that I have two lists and to navigate from one to the other I would use a horizontal swipe. I have that working. However, what ever list item your finger is on when the swipe begins executing, that item will also be long-clicked. Here is the relevant code I have: public class MyActivity extends Activity implements OnItemClickListener, OnClickListener { private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_MAX_OFF_PATH = 250; private static final int SWIPE_THRESHOLD_VELOCITY = 200; private GestureDetector mGestureDetector; View.OnTouchListener mGestureListener; class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) return false; // right to left swipe if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { if (mCurrentScreen != SCREEN_SECONDLIST) { mCurrentScreen = SCREEN_SECONDLIST; mFlipper.setInAnimation(inFromRightAnimation()); mFlipper.setOutAnimation(outToLeftAnimation()); mFlipper.showNext(); updateNavigationBar(); } } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { if (mCurrentScreen != SCREEN_FIRSTLIST) { mCurrentScreen = SCREEN_FIRSTLIST; mFlipper.setInAnimation(inFromLeftAnimation()); mFlipper.setOutAnimation(outToRightAnimation()); mFlipper.showPrevious(); updateNavigationBar(); } } } catch (Exception e) { // nothing } return true; } } @Override public boolean onTouchEvent(MotionEvent event) { if (mGestureDetector.onTouchEvent(event)) return true; else return false; } ViewFlipper mFlipper; private int mCurrentScreen = SCREEN_FIRSTLIST; private ListView mList1; private ListView mList2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.layout_flipper); mFlipper = (ViewFlipper) findViewById(R.id.flipper); mGestureDetector = new GestureDetector(new MyGestureDetector()); mGestureListener = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (mGestureDetector.onTouchEvent(event)) { return true; } return false; } }; // set up List1 screen mList1List = (ListView)findViewById(R.id.list1); mList1List.setOnItemClickListener(this); mList1List.setOnTouchListener(mGestureListener); // set up List2 screen mList2List = (ListView)findViewById(R.id.list2); mList2List.setOnItemClickListener(this); mList2List.setOnTouchListener(mGestureListener); } … } If I change the "return true;" statement from the GestureDetector to "return false;", I do not get long-clicks. Unfortunately, I get regular clicks. Does anyone know how I can get around this?

  • DBMS for POS software

    - by Andrew Smith
    Hello, I want to develop a POS application in .NET (C#) that would be used to rent items. I have a good idea of what will be done and the famous question that I have is about the DBMS that I should use. I would like to use MySQL database. The question is: If some places use only one computer (no network, no internet connection), can I use a MySQL database in local? Do I need to install MySQL server on all thoses computers to be able to use such a database? I know SQLite but I'm not sure if the limitations can cause problems in the future... I also looked at SQLServer Express versions. (I must consider that other point of sales are using multiple computers and more transactions so there I can't put sqlexpress or sqlite) So can anybody suggest me what I should do in that situation? Thanks

  • 10035 error on a blocking socket

    - by Andrew
    Does anyone have any idea what could cause a 10035 error (EWOULDBLOCK) when reading on a blocking socket with a timeout? This is under Windows XP using the .NET framework version 3.5 socket library. I've never managed to get this myself, but one of my colleagues is getting it all the time. He's sending reasonably large amounts of data to a much slower device and then waiting for a response, which often gives a 10035 error. I'm wondering if there could be issues with TCP buffers filling up, but in that case I would expect the read to wait or timeount. The socket is definitely blocking, not non-blocking.

    Hi, I've got a query below. I want to add a condition that if the parameter of @IsPrestigeFeatured = 0 then update all of the other rows < PropertyId in the IsprestigeFeatured column to 0 and if @IsPrestigeFeatured = 1 then IsprestigeFeatured = 1 where propertyId = PropertyId.

  • Change Tweetmeme button colour under wordpress

    - by Andrew Bolster
    I've had a poke around in the TweetMeme plugin code and IANA JS Guru, but I cant find any sensible way to make specific styling changes; you can add div-specific CSS characteristics, but I'm talking about changing the resting colour and the hover colour of the button. I've googled around and noone seems to have asked it on here so I thought I should.

  • Oracle Hash Cluster Overflow Blocks

    - by Andrew
    When inserting a large number of rows into a single table hash cluster in Oracle, it will fill up the block with any values that hash to that hash-value and then start using overflow blocks. These overflow blocks are listed as chained off the main block, but I can not find detailed information on the way in which they are allocated or chained. When an overflow block is allocated for a hash value, is that block exclusively allocated to that hash value, or are the overflow blocks used as a pool and different hash values can then start using the same overflow block. How is the free space of the chain monitored - in that, as data is continued to be inserted, does it have to traverse the entire chain to find out if it has some free space in the current overflow chain, and then if it finds none, it then chooses to allocate a new block?

  • Positioning DIV's with Javascript

    - by Andrew P.
    I have two divs that I need to position horizontally dependent on the width of the user's screen. I've styled their vertical position in CSS, and I am trying to position them horizontally using Javascript. My divs: <div id="tl"> blah blah </div> <div id="bl"> blah blah </div> My CSS: #tl { position: absolute; top: -14px; right: 0; } #bl { position: absolute; bottom: 1px; right: 0; } My Javascript: var tl = document.getElementById('tl'); var bl = document.getElementById('bl'); var wide = parseInt(screen.width); var nudge = wide*.86; nudge = nudge+21; tl = tl.style; tl.right = ( parseInt(tl.right) + nudge ); bl = bl.style; bl.right = ( parseInt(bl.right) + nudge ); However... nothing happens. No errors, and definitely no movement from my divs. What am I doing wrong? Can anyone help?

  • Singleton Issues in iOS http client

    - by Andrew Lauer Barinov
    I implemented an HTTP client is iOS that is meant to be a singleton. It is a subclass of AFNetworking's excellent AFHTTPClient My access method is pretty standard: + (LBHTTPClient*) sharedHTTPClient { static dispatch_once_t once = 0; static LBHTTPClient *sharedHTTPClient = nil; dispatch_once(&once, ^{ sharedHTTPClient = [[LBHTTPClient alloc] initHTTPClient]; }); return sharedHTTPClient; } // my init method - (id) initHTTPClient { self = [super initWithBaseURL:[NSURL URLWithString:kBaseURL]]; if (self) { // Sub class specific initializations } return self; } Super's init method is very long, and can be found here However the problem I experience is when the dispatch_once queue is run, the app locks and become unresponsive. When I step through code, I notice that it locks on dispatch_once and then remains frozen. Is this something to do with the main thread locking down? How come it stays locked like that? Also, none of the HTTP client methods fire. Stepping through the code some more, I find this line in dispatch/once.h is where the app locks down: DISPATCH_INLINE DISPATCH_ALWAYS_INLINE DISPATCH_NONNULL_ALL DISPATCH_NOTHROW void _dispatch_once(dispatch_once_t *predicate, dispatch_block_t block) { if (DISPATCH_EXPECT(*predicate, ~0l) != ~0l) { dispatch_once(predicate, block); // App locks here } }

  • MySQL SET and ENUM types in CakePHP framework

    - by Andrew Bashtannik
    Hi! I need to use SET and ENUM types in my CakePHP 1.3 project. I found some advices, but all them are too old (2004-2006) and full of crazy methods, like modifying cake's core files. Also, CakePHP developers said that SET and ENUM types are not supported. Example: I have SET('alpha','beta') field, and I need to use this data as checkboxes in add & edit actions. Is there any way to add normal support (Form helpers etc.) of SET and ENUM fields?

Is it even possible?

  • Can anyone give me a sample DSP script in C/C++

    - by Andrew
    Im working on a (Audio) DSP project and just wondering if there are any sample (Open source) DSP example that are written in c or c++, for my MSP430 Chip. I just want something as a guideline so i can program my own script using the ACD and DCA on my board for sampling. http://focus.ti.com/docs/toolsw/folders/print/msp-exp430f5438.html Thats my board, MSP430F5438 Experimenter Board, from what i herd it can run dsp script via the USB connection with the computer. Im using CCS ( From TI, code composer studio) and Octave/Matlab. Just any DSP example scripts or sites that will help me create my own would be appreciated. What im tying to do, Partial audio (sampled) track -- Nyquist rate sampling -- over- and undersampling -- reconstruction of the audio track.

  • Issue Implementing Colorbox Correctly in IE (all versions)

    - by Andrew
    I've been pulling my hair out (and going way over allotted hours) to try and figure out why Colorbox isn't working properly on the following page: http://www.fiberforge.com I've set up a Colorbox test link on the very bottom right that says "Web Design By All Web Cafe", which should open up a small logo image. In Firefox, Safari, etc the modal behaves as it should, opening center center above all of the existing on-page content. In IE, not only is the modal not centered, but it appears as though it's not obeying absolute positioning and pushing all of the existing on-page content down below. Add to that the fact that it's not opening to the correct size and creating scrollbars next to the modal image, and we have ourselves one ugly modal. The scrollbars I can live with (by just resizing the min-height of the modal), but I can't figure out why it won't center. Let me say that I did not code this site initially and it was completed quite a few years ago, so there are quite probably numerous CSS hacks to get things to display properly, any number of which may be causing this problem. By contrast, Thickbox is also set up on this site (if you click on the "Play Video" callout in the dark blue area) and behaves correctly, though suffers from some weird sizing/padding issues, hence the desire to replace it with something a bit more modern and extensible. I can verify that there is no conflict having both of these modal scripts/CSS files concurrently as the problem still occurs with Colorbox even when Thickbox is removed entirely. Any thoughts or suggestions would be greatly appreciated.

  • Getting started in Mac Development; No Mac.... What Do?!

    - by Andrew Bolster
    Hi folks, With all the RDF et al around King Jobs' newest glass beermat, I'm getting the feeling that its a good time to add the 'iphone/ipad developer' string to my bow. One problem (two if you count not being in a financial position to slap down $1000+ for a mac) ; I am a PC head, specifically a Linux-head, and have no regular access to a Mac platform to develop on. I cannot see any way of getting my hands on iSDK without being on a Mac, (but have been known to be wrong) How hopeless is my plight and where can I go from here?

  • How to store a public key in a machine-level RSA key container

    - by Andrew Kimball
    I'm having a problem using a machine level RSA key container when storing only the public key of a public/private key pair. The following code creates a public/private pair and extracts the public key from that pair. The pair and the public key are stored in separate key containers. The keys are then obtained from those key containers at which point they should be the same as the keys going into the containers. The code works when CspProviderFlags.UseDefaultKeyContainer is specified for CspParameters.Flags (i.e. the key read back out from the PublicKey container is the same), but when CspProviderFlags.UseMachineKeyStore is specified for CspParameters.Flags the key read back from PublicKey is different. Why is the behaviour different, and what do I need to do differently to retrieve the public key from a machine-level RSA key container? var publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true, }; var publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true }; //Export the key. publicRsa.ImportParameters(publicPrivateRsa.ExportParameters(false)); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); //Dispose those two CSPs. using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); } publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); }

  • How do I make the left and right gutters different colors with 960.gs?

    - by Andrew Arrow
    How do I make the left and right gutters different colors with 960.gs? When I try something simple like: <div style="background-color: green"> <div class="container_16"> <div class="grid_16"> test </div> </div> </div> <div style="background-color: cyan"> <div class="container_16"> <div class="grid_16"> test </div> </div> </div> The green and cyan colors are ignored. Seems like the "grid_16" class removes the color for some reason? My goal is being able to have different sections of the page in different colors all the way across the page, even past 960 pixels. So if someone makes their browser 1200px the left and right sides have the right color and the rest of the grid system is all contained within the 960 pixels in the middle. I could add a background color to 'body' to do this for just 1 color, but I want multiple colors in the page. Like different colored horizontal stripes. Thanks.
