  • How to ellipsize center-aligned textview beside a right-aligned button when screen width is small

    - by simplymoody
    ------------------------------------ | LONG_TITL... |button| | |------------------------------------| | | I have an app header which consists of the app title and a button. The button should be fixed on the right side but I want the title to be in the middle and ellipsize when the screen is too small. Problem is the title just won't ellipsize even though the button is nearly beside it. Here's what I have so far: <RelativeLayout android:id="@+id/headr" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center"> <ImageView android:id="@+id/bar_orange" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:minHeight="40dp" android:scaleType="centerCrop" android:src="@drawable/bar_orange"/> <TextView android:id="@+id/Title" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center" android:text="@string/bcd" android:textColor="#FFFFFF" android:ellipsize="marquee" android:singleLine="true" android:textSize="18sp" android:textStyle="bold"/> <Button android:padding="5dp" android:id="@+id/home" android:textColor="#ffffff" android:layout_marginRight="10dp" android:layout_marginLeft="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:singleLine="true" android:background="@drawable/button_home" android:text="@string/home"/> </RelativeLayout> Is there a way to do this with just RelativeLayout?

  • 2D Ball Collisions with Corners

    - by Aaron
    I'm trying to write a 2D simulation of a ball that bounces off of fixed vertical and horizontal walls. Simulating collisions with the faces of the walls was pretty simple--just negate the X-velocity for a vertical wall or the Y-velocity for a horizontal wall. The problem is that the ball can also collide with the corners of the walls, where a horizontal wall meets with a vertical wall. I have already figured out how to detect when a collision with a corner is occurring. My question is how the ball should react to this collision--that is, how its X and Y velocities will change as a result. Here's a list of what I already know or know how to find: *The X and Y coordinates of the ball's center during the frame when a collision is detected *The X and Y components of the ball's velocity *The X and Y coordinates of the corner *The angle between the ball's center and the corner *The angle in which the ball is traveling just before the collision *The amount that the ball is overlapping the corner when the collision is detected I'm guessing that it's best to pretend that the corner is an infinitely small circle, so I can treat a collision between the ball and that circle as if the ball were colliding with a wall that runs tangent to the circles at the point of collision. It seems to me that all I need to do is rotate the coordinate system to line up with this imaginary wall, reverse the X component of the ball's velocity under this system, and rotate the coordinates back to the original system. The problem is that I have no idea how to program this. By the way, this is an ideal simulation. I'm not taking anything like friction or the ball's rotation into account. I'm using Objective-C, but I'd really just like a general algorithm or some advice. Many thanks if anyone can help!

  • AsyncPostBackTrigger disables buttons...

    - by afsharm
    I've a simple UpdatePanel and a button outside of it. I've introduced the button as an AsyncPostBackTrigger in the UpdatePanel. UpdatePanel itself works fine but the button does not. Whenever the button is clicked, its click handler does not run just like the button is not clicked at all! Why the button is not working and how can it be fixed? UPDATE: here is the markup: <asp:UpdatePanel ID="upGridView" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:GridView ID="grdList" SkinID="SimpleGridView" DataKeyNames="Key" runat="server" AllowPaging="True" PageSize="15" AutoGenerateColumns="False" Caption="<%$ Resources: CommonResources, grdListCaption %>" EmptyDataText="<%$ Resources: CommonResources, grdListEmptyDataText %>" OnRowEditing="grdList_RowEditing" OnPageIndexChanging="grdList_PageIndexChanging" OnRowCreated="grdList_RowCreated"> <Columns> </Columns> </asp:GridView> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnDelete" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="btnNew" EventName="Click" /> <asp:AsyncPostBackTrigger ControlID="btnForward" EventName="Click" /> </Triggers> </asp:UpdatePanel> <asp:Button ID="btnDelete" runat="server" SkinID="Button" Text="<%$ Resources: CommonResources, btnDelete %>" OnClick="btnDelete_Click" /> <asp:Button ID="btnNew" runat="server" SkinID="Button" Text="<%$ Resources: CommonResources, btnNew %>" OnClick="btnNew_Click" /> <asp:Button ID="btnForward" runat="server" SkinID="Button" meta:resourcekey="btnForward" OnClick="btnForward_Click" />

  • Circle drawing with SVG's arc path

    - by ????
    The following SVG path can draw 99.99% of a circle: (try it on http://jsfiddle.net/DFhUF/46/ and see if you see 4 arcs or only 2, but note that if it is IE, it is rendered in VML, not SVG, but have the similar issue) M 100 100 a 50 50 0 1 0 0.00001 0 But when it is 99.99999999% of a circle, then nothing will show at all? M 100 800 a 50 50 0 1 0 0.00000001 0 And that's the same with 100% of a circle (it is still an arc, isn't it, just a very complete arc) M 100 800 a 50 50 0 1 0 0 0 How can that be fixed? The reason is I use a function to draw a percentage of an arc, and if I need to "special case" a 99.9999% or 100% arc to use the circle function, that'd be kind of silly. Again, a test case on jsfiddle using RaphaelJS is at http://jsfiddle.net/DFhUF/46/ (and if it is VML on IE 8, even the second circle won't show... you have to change it to 0.01) Update: This is because I am rendering an arc for a score in our system, so 3.3 points get 1/3 of a circle. 0.5 gets half a circle, and 9.9 points get 99% of a circle. But what if there are scores that are 9.99 in our system? Do I have to check whether it is close to 99.999% of a circle, and use an arc function or a circle function accordingly? Then what about a score of 9.9987? Which one to use? It is ridiculous to need to know what kind of scores will map to a "too complete circle" and switch to a circle function, and when it is "a certain 99.9%" of a circle or a 9.9987 score, then use the arc function.

  • UIView coordinate transforms on rotation during keyboard appearance

    - by SG
    iPad app; I'm trying to resize my view when the keyboard appears. It amounts to calling this code at appropriate times: CGRect adjustedFrame = self.frame; adjustedFrame.size.height -= keyboardFrame.size.height; [self setFrame:adjustedFrame]; Using this technique for a view contained in a uisplitview-based app works in all 4 orientations, but I've since discovered that a vanilla uiview-based app does not work. What happens is that apparently the uisplitview is smart enough to convert the coordinates of its subviews (their frame) such that the origin is in the "viewer's top left" regardless of the orientation. However, a uiview is not able to correctly report these coordinates. Though the origin is reported as (0,0) in all orientations, the view's effective origin is always as if the ipad were upright. What is weird about this is that the view correctly rotates and draws, but it always originates in the literal device top left. How can I get the view to correctly make its origin the "top left" to the viewer, not the device's fixed top left? What am I missing? Please, for something so trivial I've spent about 6 hours on this already with every brute force technique and research angle I could think of. This is the original source which doesn't work in this case: http://stackoverflow.com/questions/1951826/move-up-uitoolbar

  • How to avoid "Illegal type in constant pool" using "ldc_w <classname>" in Jasmin?

    - by jazzdev
    I'm writing a compiler that generates Jasmin code and want to invoke a method that takes a Class as a parameter. public class CTest { public static void main(String[] args) throws Exception { java.lang.reflect.Array.newInstance(CTest.class, 0); } } So in Jasmin, I think that should be: .class public CTest2 .super java/lang/Object .method public static main([Ljava/lang/String;)V .limit stack 2 .limit locals 1 ldc_w CTest2 iconst_0 invokestatic java/lang/reflect/Array/newInstance(Ljava/lang/Class;I)Ljava/lang/Object; pop return .end method When I assemble it and run it I get: Exception in thread "main" java.lang.VerifyError: (class: CTest2, method: main signature: ([Ljava/lang/String;)V) Illegal type in constant pool Looking at the disassembled code for both CTest.class (the Java version) and CTest2.class (the Jasmin version) with "javap -c -verbose" they both appear to set up the constant pool the same way: const #2 = class #16; // CTest const #16 = Asciz CTest; 0: ldc_w #2; //class CTest const #14 = Asciz CTest2; const #17 = class #14; // CTest2 0: ldc_w #17; //class CTest2 I've fixed two bugs in Jasmin already, but I can't see what it's doing wrong when putting the class in the constant pool for "ldc_w" it puts classes in the constant pool for other instructions, like "new" and "anewarray" correctly. I've tried looking at the .class files with TraceClassVisitor in ASM, but it doesn't dump the constant pool. Any ideas what I can try next?

  • TeamCity and pending Git merge branch commit keeps build with failed tests

    - by Vladimir
    We use TeamCity for continuous integration and Git for source control. Generally it works pretty well - convenient, modern and good us quick feedback when tests fails. There is a strange behavior related to Git merge specifics. Here are steps of the case: First developer pulls from master repo. Second developer pulls from master repo. First developer makes commit A locally. Second developer makes commit B locally; Second developer pushes commit B. First developer want to push commit A but unable because he have to pull commit B first. First developer pull's from remote reposity. First developer pushes commit A and generated merge branch commit. The history of commits in master repo is following: B second developer A first developer merge branch first developer. Now let's assume that Second Developer fixed some failing tests in his commit B. What TeamCity will do is following: Commit B arrives - TeamCity makes build #1 with all tests passed Commit A arrives - TeamCity makes build #2 (without commit B) test bar becomes Red! TeamCity thought that Pending "Merge Branch" commit doesn't contain any changes (any new files) - but it actually does contain the merge of commit B, so the TeamCity don't want to make new build here and make tests green. Here are two problems: 1. In our case we have failed tests returning back in second commit (commit A) 2. TeamCity don't want to make a new build and make tests back green. Does anybody know how to fix both of this problems. I consider some reasonable general approach.

  • Google Maps: remember id of marker with open info window

    - by AP257
    I have a Google map that is showing a number of markers. When the user moves the map, the markers are redrawn for the new boundaries, using the code below: GEvent.addListener(map, "moveend", function() { var newBounds = map.getBounds(); for(var i = 0; i < places_json.places.length ; i++) { // if marker is within the new bounds then do... var latlng = new GLatLng(places_json.places[i].lat, places_json.places[i].lon); var html = "blah"; var marker = createMarker(latlng, html); map.addOverlay(marker); } }); My question is simple. If the user has clicked on a marker so that it is showing an open info window, currently when the boundaries are redrawn the info window is closed, because the marker is added again from scratch. How can I prevent this? It is not ideal, because often the boundaries are redrawn when the user clicks on a marker and the map moves to display the info window - so the info window appears and then disappears again :) I guess there are a couple of possible ways: remember which marker has an open info window, and open it again when the markers are redrawn don't actually re-add the marker with an open info window, just leave it there However, both require the marker with an open window to have some kind of ID number, and I don't know that this is actually the case in the Google Maps API. Anyone? ----------UPDATE------------------ I've tried doing it by loading the markers into an initial array, as suggested. This loads OK, but the page crashes after the map is dragged. <script type="text/javascript" src="{{ MEDIA_URL }}js/markerclusterer.js"></script> <script type='text/javascript'> function createMarker(point,html, hideMarker) { //alert('createMarker'); var icon = new GIcon(G_DEFAULT_ICON); icon.image = "http://chart.apis.google.com/chart?cht=mm&chs=24x32&chco=FFFFFF,008CFF,000000&ext=.png"; var tmpMarker = new GMarker(point, {icon: icon, hide: hideMarker}); GEvent.addListener(tmpMarker, "click", function() { tmpMarker.openInfoWindowHtml(html); }); return tmpMarker; } var map = new GMap2(document.getElementById("map_canvas")); map.addControl(new GSmallMapControl()); var mapLatLng = new GLatLng({{ place.lat }}, {{ place.lon }}); map.setCenter(mapLatLng, 12); map.addOverlay(new GMarker(mapLatLng)); // load initial markers from json array var markers = []; var initialBounds = map.getBounds(); for(var i = 0; i < places_json.places.length ; i++) { var latlng = new GLatLng(places_json.places[i].lat, places_json.places[i].lon); var html = "<strong><a href='/place/" + places_json.places[i].placesidx + "/" + places_json.places[i].area + "'>" + places_json.places[i].area + "</a></strong><br/>" + places_json.places[i].county; var hideMarker = true; if((initialBounds.getSouthWest().lat() < places_json.places[i].lat) && (places_json.places[i].lat < initialBounds.getNorthEast().lat()) && (initialBounds.getSouthWest().lng() < places_json.places[i].lon) && (places_json.places[i].lon < initialBounds.getNorthEast().lng()) && (places_json.places[i].placesidx != {{ place.placesidx }})) { hideMarker = false; } var marker = createMarker(latlng, html, hideMarker); markers.push(marker); } var markerCluster = new MarkerClusterer(map, markers, {maxZoom: 11}); </script>

  • SQL Agent Logon - What is going on?

    - by James Wiseman
    I have a DTSX package that is called from a SQL Agent Job. The DTSX package references a file at a fixed location (e.g. e:\mssql\myfile.txt). On most machines, this location exists, but on some I have to manually map this (which is not a problem - I know a better solution would be to use package conifgurations to dynamically pull the file location, but this is not an option here - and anyway I'd like to understand what is going on) I have set up the agent service to run as a specific user (e.g. myuser) When I log on as this user and map the directory, then run the dtsx package directly, then all goes well. When I run the package through a SQL Agent Job, the file cannot be found. If I add a command line job step to the agent job to map the drive: net use e: \\svr\location Then all works file also. So what is going on in the backgound? How come the SQL Agent user requries the drive mapping even when I am logged in as this user.

  • Visual Studio 2005 - OleDbConnection throws "Invalid authorization specification" in Form Designer,

    - by Jason Dagit
    I have a form with an OleDbConnection object on it. This form fails to load in the Form Designer with the message: One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes. Invalid authorization specification at ADODB.ConnectionClass.Open(String ConnectionString, String UserID, String Password, Int32 Options) ... (stack trace continues into user code) I've tracked this down to the OleDbConnection string. If I hardcode in the server IP, username/password/dbinstance into the constructor of the GUI form then the form will load in the designer. At run-time it is not an issue because we require the user to provide the login details. The question: Is it possible to use the OleDbConnection and the Form designer without supplying the database credentials in the source code of the form? For example, is there a property of the OleDbConnection or Form that I can set so that it doesn't need to access the database during Form design? My concern is that if we ever move the database server or change the login that the code will stop working in the designer.

  • Android Layout: Display as much ImageViews as possible without scrolling

    - by Toni4780
    I am working on an app which should display several same size images on the screen. But it should only display only so much images as possible without offering scrolling. E.g. On a "big" tablet it could display 10x10 Imageviews (screen is large, so there is much space for pictures) On a "big" phone there might be enough space to display 6x6 ImageViews, so it should only display a 6x6 array of images. On a small phone there is propably only space for 4x4 ImageViews, so it should only display this. How can I make this in Android? I know about "layout-large", ... but if i make a special fixed xml-layout for a "large" device, it would not fit all devices correct. E.g. a Galaxy Nexus is a "normal" device and so is a Nexus One, but there would be at least be space for one or two more imageview rows on a Galaxy Nexus than on a Nexus One. So do I have to measure in code somehow how big the resolution is and display some TableRows accordingly? Or is there a special way how I can manage this?

  • Dynamically created iframe used to download file triggers onload with firebug but not without

    - by justkt
    EDIT: as this problem is now "solved" to the point of working, I am looking to have the information on why. For the fix, see my comment below. I have an web application which repeatedly downloads wav files dynamically (after a timeout or as instructed by the user) into an iframe in order to trigger the a default audio player to play them. The application targets only FF 2 or 3. In order to determine when the file is downloaded completely, I am hoping to use the window.onload handler for the iframe. Based on this stackoverflow.com answer I am creating a new iframe each time. As long as firebug is enabled on the browser using the application, everything works great. Without firebug, the onload never fires. The version of firebug is 1.3.1, while I've tested Firefox 2.0.0.19 and 3.0.7. Any ideas how I can get the onload from the iframe to reliably trigger when the wav file has downloaded? Or is there another way to signal the completion of the download? Here's the pertinent code: HTML (hidden's only attribute is display:none;): <div id="audioContainer" class="hidden"> </div> JavaScript (could also use jQuery, but innerHTML is faster than html() from what I've read): waitingForFile = true; // (declared at the beginning of closure) $("#loading").removeClass("hidden"); var content = "<iframe id='audioPlayer' name='audioPlayer' src='" + /path/to/file.wav + "' onload='notifyLoaded()'></iframe>"; document.getElementById("audioContainer").innerHTML = content; And the content of notifyLoaded: function notifyLoaded() { waitingForFile = false; // (declared at beginning of the closure) $("#loading").addClass("hidden"); } I have also tried creating the iframe via document.createElement, but I found the same behavior. The onload triggered each time with firebug enabled and never without it. EDIT: Fixed the information on how the iframe is being declared and added the callback function code. No, no console.log calls here.

  • iPhone accelerometer:didAccelerate: seems to not get called while I am running a loop

    - by AJ
    An accelerometer related question. (Sorry the formatting may not look right, its the first time I am using this site). I got the accelerometer working as expected using the standard code UIAccelerometer *accel = [UIAccelerometer sharedAccelerometer]; accel.delegate = self; accel.updateInterval = 0.1; //I also tried other update values I use NSLog to log every time the accelerometer:didAccelerate: method in my class is called. The function gets called as expected and everything works fine till here. However, when I run a loop, the above method doesn't seem to get called. Something like this float firstAccelValue = globalAccel; //this is the x-accel value (stored in a global by the above method) float nextAccelValue = firstAccelValue; while (nextAccelValue == firstAccelValue){ //do something nextAccelValue = globalAccel; // note globalAccel is updated by the accelerometer method } The above loop never exits, expectedly since the accelerometer:didAccelerate: method is not getting called, and hence globalAccel never changes value. If I use a fixed condition to break the while loop, I can see that after the loop ends, the method calls work fine again. Am I missing something obvious here? Or does the accelerometer method not fire when certain processing is being done? Any help would be greatly appreciated! Thanks!

  • Reading email address from contacts fails with weird memory issue - Solved

    - by CapsicumDreams
    Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount > 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on? Solution: It turned out that I wasn't storing the ABRecordRef personDealingWith var correctly. I'm still not sure how to do that properly, but instead of having the functionality in another routine (performed later), I'm now doing the grunt-work in the delegate method, and using the derived results at my leisure. The new (working) routine: - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person { // as soon as they select someone, return personDealingWithFullName = (NSString *)ABRecordCopyCompositeName(person); personDealingWithFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); // construct array of emails [personDealingWithEmails removeAllObjects]; ABMutableMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty); if (ABMultiValueGetCount(multi) > 0) { // collect all emails in array for (CFIndex i = 0; i < ABMultiValueGetCount(multi); i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [personDealingWithEmails addObject:(NSString *)emailRef]; CFRelease(emailRef); } } CFRelease(multi); return NO; }

  • GWT Html Layout Conventions

    - by brad
    I've just started working with GWT and I'm already recognizing the extraordinary power that it possesses. I'm coming from a frontend world so the Java is a big learning curve, but I think that will actually help me build a properly laid out app (html-wise) instead of just relying on the default GWT panels that often end up using tables for layout, or superfluous, absolutely positioned divs. The biggest thing slowing me down right now however is deciding how to properly lay out the design of my site. I've got a pretty standard 2-col header/foot site (fixed width) that I want to design, but I'm not a fan of all the extra divs/styling etc that come with the DockLayoutPanel for instance. I'm thinking that I should just write my own Layout widget extending Composite that has HTMLPanels for the general site layout (I think... still haven't fully figured that out yet, ie. how do I add ID's to these panel divs "#header", "#nav" etc...) then I can add other widgets into this layout But the other thing I'm seeing is that I could write a Layout class extending UiBuilder and have straight up divs in the ui.xml file. I'm just wondering, what is the preferred method for site layout with GWT? This isn't going to be re-used in the sense of other widgets, it will be used once and my controls etc will be placed inside. Any tips or tricks are greatly appreciated! And if I've completely missed the boat on how to do this, let me know

  • Invalid iPhone Application Binary

    - by Kristopher Johnson
    I'm trying to upload an application to the iPhone App Store, but I get this error message from iTunes Connect: The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certificate. My guess is that it is not properly signed. I have downloaded my App Store distribution certficate, but I can't figure out how to "sign" my application with it. The SDK's documentation about code signing is not very helpful. (FWIW, I can install the app on my iPhone just fine using the development provisioning profile.) However, it is possible that I screwed things up on a more basic level. Here's what I did to try to prepare it for upload: In Xcode, select the Device|Release target Select the target and click the Info button. Change "Code Signing Identity" to "iPhone Distribution", and change "Code Signing Provisioning Profile" to my App Store distribution profile. Build Go to the directory where the built MyApp.app bundle is, control-click and choose "Compress" to create MyApp.zip Upload MyApp.zip to the App Store via iTunes Connect (which resulted in the above error message). Can anybody give me any hints? Edit: Found someone with the same problem. Unfortunately, he won't tell us how he fixed it. http://www.rhonabwy.com/wp/2008/07/18/seattlebus-diary-ongoing-update-saga/#comments http://www.rhonabwy.com/wp/2008/07/22/seattlebus-diary-update-is-pending-review/ (Note: For general information on submitting iPhone applications to the App Store, see Steps to upload an iPhone application to the AppStore.)

  • LocalAlloc and LocalRealloc usage

    - by PaulH
    I have a Visual Studio 2008 C++ Windows Mobile 6 application where I'm using a FindFirst() / FindNext() style API to get a collection of items. I do not know how many items will be in the list ahead of time. So, I would like to dynamically allocate an array for these items. Normally, I would use a std::vector<>, but, for other reasons, that's not an option for this application. So, I'm using LocalAlloc() and LocalReAlloc(). What I'm not clear on is if this memory should be marked fixed or moveable. The application runs fine either way. I'm just wondering what's 'correct'. int count = 0; INFO_STRUCT* info = ( INFO_STRUCT* )LocalAlloc( LHND, sizeof( INFO_STRUCT ) ); while( S_OK == GetInfo( &info[ count ] ) { ++count; info = ( INFO_STRUCT* )LocalRealloc( info, sizeof( INFO_STRUCT ) * ( count + 1 ), LHND ); } if( count > 0 ) { // use the data in some interesting way... } LocalFree( info ); Thanks, PaulH

  • [ActionScript 3] Array subclasses cannot be deserialized, Error #1034

    I've just found a strange error when deserializing from a ByteArray, where Vectors cannot contain types that extend Array: there is a TypeError when they are deserialized.

    I've recently started tinkering with ASP.NET MVC, but this question should apply to classic ASP.NET as well. For what it's worth, I don't know very much about forms authentication and membership providers either. I'm trying to write my own MembershipProvider which will be connected to my own custom user table in my database. My user table contains all of the basic user information such as usernames, passwords, password salts, e-mail addresses and so on, but also information such as first name, last name and country of residence. As far as I understand, the standard way of doing this in ASP.NET is to create a user table without the extra information and then a "profile" table with the extra information. However, this doesn't sound very good to me, because whenever I need to access that extra information I would have to make one extra database query to get it. I read in the book "Pro ASP.NET 3.5 in C# 2008" that having a separate table for the profiles is not a very good idea if you need to access the profile table a lot and have many different pages in your website. Now for the problem at hand... As I said, I'm writing my own custom MembershipProvider subclass and it's going pretty well so far, but now I've come to realize that the CreateUser doesn't allow me to create users in the way I'd like. The method only takes a fixed number of arguments and first name, last name and country of residence are not part of them. So how would I create an entry for the new user in my custom table without this information at hand in CreateUser of my MembershipProvider?

  • Optimizing mathematics on arrays of floats in Ada 95 with GNATC

    - by mat_geek
    Consider the bellow code. This code is supposed to be processing data at a fixed rate, in one second batches, It is part of an overal system and can't take up too much time. When running over 100 lots of 1 seconds worth of data the program takes 35 seconds; or 35%. How do I improce the code to get the processing time down to a minimum? The code will be running on an Intel Pentium-M which is a P3 with SSE2. package FF is new Ada.Numerics.Generic_Elementary_Functions(Float); N : constant Integer := 820; type A is array(1 .. N) of Float; type A3 is array(1 .. 3) of A; procedure F(state : in out A3; result : out A3; l : in A; r : in A) is s : Float; t : Float; begin for i in 1 .. N loop t := l(i) + r(i); t := t / 2.0; state(1)(i) := t; state(2)(i) := t * 0.25 + state(2)(i) * 0.75; state(3)(i) := t * 1.0 /64.0 + state(2)(i) * 63.0 /64.0; for r in 1 .. 3 loop s := state(r)(i); t := FF."**"(s, 6.0) + 14.0; if t > MAX then t := MAX; elsif t < MIN then t := MIN; end if; result(r)(i) := FF.Log(t, 2.0); end loop; end loop; end;

  • HTML Element doesn't display when served with php5, restart server with php4 and Element displays.

    - by togglemedia
    Get this...I start the server in php5 and a specific HTML element ('a' element with a background image) is nowhere to be seen, I reboot the server in php4 and the HTML element is displaying properly. I boot back and forth between php5 and php4 with absolute consistent results, not displaying in php5 and displaying in php4. The thing that blows my mind is that: the HTML is consistent between boots of php5/4, so both scenarios have the necessary HTML elements the CSS is consistent between boots of php5/4, so both scenarios have the necessary CSS definitions there is an identically styled sibling element, with different class name that displays properly the problem is reproducible between browsers, between platforms. I've tested it on every possible config, Mac/Windows, IE6,7,8, FireFox, Safari etc... When the server is booted in php5 there is one HTML element that just doesn't display/render. A stab in the dark, I turned on PHP error reporting in php5 (to see if there would be any clues there) and low and behold the HTML element is now rendering in php5. I turn off PHP error reporting, and restart php5 and the HTML element is still rendering in php5, and the problem has been fixed...and I can't get the problem to reproduce. This is why my curiosity has brought me here. I just spent about four hours scratching my head trying to figure out how this could be. And now, I ask any php web dev gurus out there...what the heck was this all about?

  • How can I get Firefox to update background-color on a:hover *before* a javascript routine is run?

    - by Rob
    I'm having a Firefox-specific issue with a script I wrote to create 3d layouts. The correct behavior is that the script pulls the background-color from an element and then uses that color to draw on the canvas. When a user mouses over a link and the background-color changes to the :hover rule, the color being drawn changes on the canvas changes as well. When the user mouses out, the color should revert back to non-hover color. This works as expected in Webkit browsers and Opera, but it seems like Firefox doesn't update the background-color in CSS immediately after a mouseout event occurs, so the current background-color doesn't get drawn if a mouseout occurs and it isn't followed up by another event that calls the draw() routine. It works just fine in Opera, Chrome, and Safari. How can I get Firefox to cooperate? I'm including the code that I believe is most relevant to my problem. Any advice on how I fix this problem and get a consistent effect would be very helpful. function drawFace(coord, mid, popColor,gs,x1,x2,side) { /*Gradients in our case run either up/down or left right. We have two algorithms depending on whether or not it's a sideways facing piece. Rather than parse the "rgb(r,g,b)" string(popColor) retrieved from elsewhere, it is simply offset with the gs variable to give the illusion that it starts at a darker color.*/ var canvas = document.getElementById('depth'); //This is for excanvas.js var G_vmlCanvasManager; if (G_vmlCanvasManager != undefined) { // ie IE G_vmlCanvasManager.initElement(canvas); } //Init canvas if (canvas.getContext) { var ctx = canvas.getContext('2d'); if (side) var lineargradient=ctx.createLinearGradient(coord[x1][0]+gs,mid[1],mid[0],mid[1]); else var lineargradient=ctx.createLinearGradient(coord[0][0],coord[2][1]+gs,coord[0][0],mid[1]); lineargradient.addColorStop(0,popColor); lineargradient.addColorStop(1,'black'); ctx.fillStyle=lineargradient; ctx.beginPath(); //Draw from one corner to the midpoint, then to the other corner, //and apply a stroke and a fill. ctx.moveTo(coord[x1][0],coord[x1][1]); ctx.lineTo(mid[0],mid[1]); ctx.lineTo(coord[x2][0],coord[x2][1]); ctx.stroke(); ctx.fill(); } } function draw(e) { var arr = new Array() var i = 0; var mid = new Array(2); $(".pop").each(function() { mid[0]=Math.round($(document).width()/2); mid[1]=Math.round($(document).height()/2); arr[arr.length++]=new getElemProperties(this,mid); i++; }); arr.sort(sortByDistance); clearCanvas(); for (a=0;a<i;a++) { /*In the following conditional statements, we're testing to see which direction faces should be drawn, based on a 1-point perspective drawn from the midpoint. In the first statement, we're testing to see if the lower-left hand corner coord[3] is higher on the screen than the midpoint. If so, we set it's gradient starting position to start at a point in space 60pixels higher(-60) than the actual side, and we also declare which corners make up our face, in this case the lower two corners, coord[3], and coord[2].*/ if (arr[a].bottomFace) drawFace(arr[a].coord,mid,arr[a].popColor,-60,3,2); if (arr[a].topFace) drawFace(arr[a].coord,mid,arr[a].popColor,60,0,1); if (arr[a].leftFace) drawFace(arr[a].coord,mid,arr[a].popColor,60,0,3,true); if (arr[a].rightFace) drawFace(arr[a].coord,mid,arr[a].popColor,-60,1,2,true); } } $("a.pop").bind("mouseenter mouseleave focusin focusout",draw); If you need to see the effect in action, or if you want the full javascript code, you can check it out here: http://www.robnixondesigns.com/strangematter/

  • How to disable Safari Reader in a web page

    - by michael
    I'm curious to know more about what triggers the Reader option in Safari and what does not. I wouldn't plan to implement anything that would disable it, but curious as a technical exercise. Here is what I've learned so far with some basic playing around: You need at least one H tag It does not go by character count alone but by the number of P tags and length Probably looks for sentence breaks '.' and other criteria Safari will provide the 'Reader' if, with a H tag, and the following: 1 P tag, 2417 chars 4 P tags, 1527 chars 5 P tags, 1150 chars 6 P tags, 862 chars If you subtract 1 character from any of the above, the 'Reader' option is not available. I should note that the character count of the H tag plays a part but sadly did not realize this when I determined the results above. Assume 20+ characters for H tag and fixed throughout the results above. Some other interesting things: Setting <p style="display:none;"> for P tags removes them from the count Setting display to none, and then showing them 230ms later with Javascript avoided the Reader option too I'd be interested if anyone can determine this in full.

  • Disabling redraw in WinForms app

    - by Ryan
    I'm working on a C#.Net application which has a somewhat annoying bug in it. The main window has a number of tabs, each of which has a grid on it. When switching from one tab to another, or selecting a different row in a grid, it does some background processing, and during this the menu flickers as it's redrawn (File, Help, etc menu items as well as window icon and title). I tried disabling the redraw on the window while switching tabs/rows (WM_SETREDRAW message) at first. In one case, it works perfectly. In the other, it solves the immediate bug (title/menu flicker), but between disabling the redraw and enabling it again, the window is "transparent" to mouse clicks - there's a small window (<1 sec) in which I can click and it will, say, highlight an icon on my desktop, as if the app wasn't there at all. If I have something else running in the background (Firefox, say) it will actually get focus when clicked (and draw part of the browser, say the address bar.) Here's code I added. m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)0; //disable redraw m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); <snip - Application ignores clicks while in this section (in one case) m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)1; //enable m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); System.Windows.Forms.Application.OpenForms[0].Refresh(); Does anyone know if a) there's a way to fix the transparent-application problem here, or b) if I'm doing it wrong in the first place and this should be fixed some other way?

  • Rails 2.3.11 Server Crashing After 4 Requests

    - by Taka
    I have a Rails 2.3.11 application running on my local Windows machine using InstantRails. I cd to my application directory, run ruby script/server to start the server running, and point my browser to localhost:3000. I get the page I expect, and am able to click a few links to other pages (all of them are static). The problem starts when I load the 4th page or so. My server crashes, with this message: Processing HomeController#index (for 127.0.0.1 at 2012-06-23 15:48:40) [GET] Rendering template within layouts/application Rendering home/index Completed in 11ms (View: 9, DB: 1) | 200 OK [http://localhost/index] C:/rails/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.11/lib/active_support/memoizable.rb:46: [BUG] Segmentation fault ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-mingw32] This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. I've uninstalled this gem and reinstalled it, which didn't help. It doesn't seem to be the gem though, because the segmentation fault sometimes occurs in C:/rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/lib/mongrel.rb:114 or C:/rails/ruby/lib/ruby/1.8/benchmark.rb:306 Versions: >ruby -v ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-mingw32] >rails -v Rails 2.3.11 I'd like to get this fixed so while I'm developing I don't have to keep restarting my server. Any suggestions?
