  • Android relative layout problem

    - by DixieFlatline
    Hello! I just can't display the button at the bottom of the screen. I have 2 textviews and 2 edittexts set as gone, and they become visible when user clicks checkbox. It's only then that my button gets positioned properly Otherwise it sits on top of the app at launch of my app.(see here: http://www.shrani.si/f/3V/10G/4nnH4DtV/layoutproblem.png) I also tried android:layout_alignParentBottom="true" but that doesnt help either. <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/scrollview" android:layout_width="fill_parent" android:layout_height="wrap_content"> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/txt1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Krajevna skupnost: " android:layout_alignParentTop="true" /> <Spinner android:id="@+id/spinner1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:prompt="@string/ks_prompt" android:layout_below="@id/txt1" /> <TextView android:id="@+id/txt2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Zadeva: " android:layout_below="@id/spinner1" /> <Spinner android:id="@+id/spinner2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:prompt="@string/pod_prompt" android:layout_below="@id/txt2" /> <TextView android:id="@+id/tv1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Zadeva: " android:layout_below="@id/spinner2" /> <EditText android:id="@+id/prvi" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/tv1" /> <TextView android:id="@+id/tv2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/prvi" android:text="Vsebina: " /> <EditText android:id="@+id/drugi" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/tv2" /> <CheckBox android:id="@+id/cek" android:text="Obvešcaj o odgovoru" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/drugi" /> <TextView android:id="@+id/tv3" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/cek" android:text="Email: " android:visibility="gone"/> <EditText android:id="@+id/tretji" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/tv3" android:visibility="gone" /> <TextView android:id="@+id/tv4" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/tretji" android:visibility="gone" android:text="Telefon: " /> <EditText android:id="@+id/cetrti" android:layout_width="fill_parent" android:layout_height="wrap_content" android:visibility="gone" android:layout_below="@id/tv4" /> <Button android:id="@+id/gumb" android:text="Klikni" android:typeface="serif" android:textStyle="bold" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:layout_below="@id/cetrti" /> </RelativeLayout> </ScrollView>

  • Are PackageMaker installations with preinstall scripts broken on Snow Leopard?

    - by Stu Thompson
    Everything worked on 10.5, but now my PackageMaker installation project is broken. I've been fighting a problem for a few days now, and either Snow Leopard (OS X 10.6.1) has broken PackageMaker installations I am lacking a very, very basic tidbit of knowledge To narrow down the problem, I've gotten to this point: Create a new PackageMaker installation Have it install a jpeg image into my home directoy Define a preinstall script that does nothing #/bin/sh exit 0 Run the above...and watch it fail with the below error message like clock work Sep 14 15:09:45 manoa installd[5620]: PackageKit: ----- Begin install ----- Sep 14 15:09:45 manoa installd[5620]: PackageKit: request=PKInstallRequest <1 packages, destination=/> Sep 14 15:09:45 manoa installd[5620]: PackageKit: packages=(\n "PKLeopardPackage <file://localhost/Users/stu/Desktop/asdf.pkg>"\n) Sep 14 15:09:46 manoa installd[5620]: PackageKit: Extracting /Users/stu/Desktop/asdf.pkg (destination=/var/folders/Hb/HbXJFyEpFaupt5QyLN-pTk+++TI/-Tmp-/PKInstallSandbox-tmp/Root/~, uid=501) Sep 14 15:09:46 manoa installd[5620]: PackageKit: Executing script "./preinstall" in /private/tmp/PKInstallSandbox.cmlS2H/Scripts/test.test.5year_header.pkg.PFrHNB Sep 14 15:09:46 manoa installd[5620]: PackageKit: *** launch path not accessible Sep 14 15:09:46 manoa installd[5620]: PackageKit: Install Failed: PKG: pre-install scripts for "test.test.5year_header.pkg"\nError Domain=PKInstallErrorDomain Code=112 UserInfo=0x100149430 "An error occurred while running scripts from the package “asdf”." {\n NSFilePath = "./preinstall";\n NSLocalizedDescription = "An error occurred while running scripts from the package \U201casdf\U201d.";\n NSURL = "file://localhost/Users/stu/Desktop/asdf.pkg";\n PKInstallPackageIdentifier = "test.test.5year_header.pkg";\n} Sep 14 15:09:46 manoa Installer[5614]: install:didFailWithError:Error Domain=PKInstallErrorDomain Code=112 UserInfo=0x1195917c0 "An error occurred while running scripts from the package “asdf”."

There is no file in /private/tmp/PKInstallSandbox.cmlS2H/Scripts/test.test.5year_header.pkg.PFrHNB/, which makes me think the problem is with PackageMaker, and not me. But I'm new to the world of OS X software installation, so doubts remain. So, the question: Is PackageMaker with a preinstall script broken on OS X 10.6? Or is there some requirement regarding preinstall scripts that I do not understand?

  • General advice and guidelines on how to properly override object.GetHashCode()

    - by Svish
    According to MSDN, a hash function must have the following properties: If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare as equal, the GetHashCode methods for the two object do not have to return different values. The GetHashCode method for an object must consistently return the same hash code as long as there is no modification to the object state that determines the return value of the object's Equals method. Note that this is true only for the current execution of an application, and that a different hash code can be returned if the application is run again. For the best performance, a hash function must generate a random distribution for all input. I keep finding myself in the following scenario: I have created a class, implemented IEquatable<T> and overridden object.Equals(object). MSDN states that: Types that override Equals must also override GetHashCode ; otherwise, Hashtable might not work correctly. And then it usually stops up a bit for me. Because, how do you properly override object.GetHashCode()? Never really know where to start, and it seems to be a lot of pitfalls. Here at StackOverflow, there are quite a few questions related to GetHashCode overriding, but most of them seems to be on quite particular cases and specific issues. So, therefore I would like to get a good compilation here. An overview with general advice and guidelines. What to do, what not to do, common pitfalls, where to start, etc. I would like it to be especially directed at C#, but I would think it will work kind of the same way for other .NET languages as well(?). I think maybe the best way is to create one answer per topic with a quick and short answer first (close to one-liner if at all possible), then maybe some more information and end with related questions, discussions, blog posts, etc., if there are any. I can then create one post as the accepted answer (to get it on top) with just a "table of contents". Try to keep it short and concise. And don't just link to other questions and blog posts. Try to take the essence of them and then rather link to source (especially since the source could disappear. Also, please try to edit and improve answers instead of created lots of very similar ones. I am not a very good technical writer, but I will at least try to format answers so they look alike, create the table of contents, etc. I will also try to search up some of the related questions here at SO that answers parts of these and maybe pull out the essence of the ones I can manage. But since I am not very stable on this topic, I will try to stay away for the most part :p

  • Android: manifest targetSdkVersion change resulted in: icon not visible, widget no longer works, and

    - by Casey
    I recently upgraded my Android app to support multiple resolutions. Previously, my Android.manifest file had a line: To support multiple density and resolution devices, I changed this to: <supports-screens android:smallScreens="false" android:normalScreens="true" android:largeScreens="true" android:anyDensity="true" /> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4" /> I then added a couple of new directories, like drawable-hdpi-v4 and drawable-long-hdpi-v4 that includes the high-res versions of the graphics. That's about it. Ever since releasing this update, there have been a decent number of users complaining about various problems: - the app icon doesn't appear (I did not create a high res version of the icon) - the home screen widget no longer works, even if they delete and re-add it (this code did not change with the update). I've had a user send me their error log, which shows: 03-19 20:59:41.617 W/ActivityManager( 1854): Unable to launch app com.alt12.babybump/10078 for broadcast Intent { action=android.appwidget.action.APPWIDGET_UPDATE flags=0x4 comp={com.alt12.babybump/com.alt12.babybump.WidgetGirl} (has extras) }: process is bad There is one questionable section in my existing widget code that may be relevant: @Override public void onReceive(Context context, Intent intent) { // v1.5 fix that doesn't call onDelete Action final String action = intent.getAction(); if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { super.onReceive(context, intent); } } And perhaps most troublesome: the sqlite database is no longer accessible/writeable for some users so their data is no longer available. I did add the WRITE_EXTERNAL_STORAGE permission to the manifest. This is only happening to certain users and it tends to be HTC Eris users. In that error log I see things such as: 03-19 16:00:56.173 E/FlurryAgent( 4791): java.io.FileNotFoundException: /data/data/com.alt12.babybump/files/.flurryagent.-2333f5cb 03-19 16:00:56.173 E/FlurryAgent( 4791): at org.apache.harmony.luni.platform.OSFileSystem.open(OSFileSystem.java:231) 03-19 16:01:09.393 E/Database( 4791): sqlite3_open_v2("/data/data/com.alt12.babybump/databases/uitematmamad.db", &handle, 6, NULL) failed 03-19 16:01:09.393 W/System.err( 4791): android.database.sqlite.SQLiteException: unable to open database file It's as if the update has caused a new process and it can't access the old process's data, or something. Any help appreciated!

  • Clickable widgets in android

    - by Leif Andersen
    The developer documentation has seemed to have failed me here. I can create a static widget without thinking, I can even create a widget like the analogue clock widget that will update itself, however, I can not for the life of me figure out how to create a widget that reacts to when a user clicks on it. Here is the best code sample that the developer documentation gives to what a widget activity should contain (the only other hint being the API demos, which only creates a static widget): public class ExampleAppWidgetProvider extends AppWidgetProvider { public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { final int N = appWidgetIds.length; // Perform this loop procedure for each App Widget that belongs to this provider for (int i=0; i<N; i++) { int appWidgetId = appWidgetIds[i]; // Create an Intent to launch ExampleActivity Intent intent = new Intent(context, ExampleActivity.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); // Get the layout for the App Widget and attach an on-click listener to the button RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider_layout); views.setOnClickPendingIntent(R.id.button, pendingIntent); // Tell the AppWidgetManager to perform an update on the current App Widget appWidgetManager.updateAppWidget(appWidgetId, views); } } } from: The Android Developer Documentation's Widget Page So, it looks like pending intent is called when the widget is clicked, which is based off of an intent (I'm not quite sure what the difference between an intent and a pending intent is), and the intent is for the ExampleActivity class. So I made my sample activity class a simple activity that when created, would create a mediaplayer object, and start it (it wouldn't ever release the object, so it would eventually crash, here is it's code: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.sound); mp.start(); } However, when I added the widget to the home screen, and clicked on it, nothing played, in fact, nothing played when I set the update timer to just a few hundred milliseconds (in the appwidget provider xml file). Furthermore, I set break points and found out that not only was it never reaching the activity, but no break points I set would ever get triggered. (I still haven't figured out why that is), however, logcat seemed to indicate that the activity class file was being run. So, is there anything I can do to get an appwidget to respond to a click? As the onClickPendingIntent() method is the closest I have found to a onClick type of method. Thank you very much.

  • Cannot use standard android color attribute in custom color selector

    - by Manish Gupta
    So, android defines the following in themes.xml: <style name="Theme"> ... <item name="colorPressedHighlight">@color/legacy_pressed_highlight</item> </style> and: <style name="Theme.Holo"> ... <item name="colorPressedHighlight">@color/holo_blue_light</item> </style> I want to use this colorPressedHighlight as the background color for my custom Button when it is pressed. So I defined the following in res/color/app_button_background.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_pressed="true" android:drawable="?android:colorPressedHighlight"/> <item android:drawable="@android:color/transparent" /> </selector> Finally, I define my custom ImageButton style: <style name="App_ImageButtonStyle" parent="@android:style/Widget.ImageButton"> <item name="android:gravity">center</item> <item name="android:background">@color/app_button_background</item> </style> I crash on app launch with the following call stack: 06-27 20:24:41.954: E/AndroidRuntime(532): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.StateListDrawable.inflate(StateListDrawable.java:178) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:867) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXml(Drawable.java:804) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.content.res.Resources.loadDrawable(Resources.java:1920) I know that directly accessing @color/legacy_pressed_highlight or @color/holo_blue_light instead of accessing them through the colorPressedHighlight fixes the crash but it does not solve the problem. Themes can vary, hence I need to access it through the colorPressedHighlight attribute. PS: I had a similar problem to which I haven't found an answer yet. Can someone please help!

  • OCR an RSA key fob (security token)

    - by user130582
    I put together a quick WinForm/embedded IE browser control which logs into our company's bank website each morning and scrapes/exports the desired deposit information (the bank is a smallish regional bank). Since we have a few dozen "pseudoaccounts" that draw from the same master account, this actually takes 10-15 minutes to retrieve. Anyway, the only problem is that our business bank account reuires an RSA security token (http://www.rsa.com/node.aspx?id=1156)--if you are not familiar, it is a small device which shows a random 6 digit number every 15(?) seconds, so I have to prompt for this value before starting. This is on top of the website's login based security model, so even if you create a read-only account that can't do anything, you still have to put the RSA number in. We have 5 of these tokens for different people in the company. From our perspective this is nusiance security. I was joking about using a web camera to OCR the digits from the key fob so they didn't have to type it in -- mainly so that the scraping/export would be done before anyone arrives in the morning. Well, they asked if I could really do it. So now I ask you, how hard (how many hours) do you think it would take to OCR these digits reliably from a JPEG image produced by the camera? I already know I can get the JPEG easily. I think you get 3 tries to log in, so it really needs to hit a 99% accuracy rate. I could work on this on my off time, but they don't want me to put more than a few hours into it, so I want to leverage as much existing code as possible. This is a 7-segment display (like an alarm clock) so it's not exactly text that an OCR package would be used to seeing. Also--there is a countdown timer on the side of the display; typically when it is down to 1 bar, you wait until the next number appears and it starts over at 5 bars (like signal strength on your cell phone). So this would need to be OCRd as well but it is not text. Anyway the more I think about it as I type this, the less convinced I am that I can truly get this right, so maybe I should just work on it in my spare time?

  • How to stop UITableView moveRowAtIndexPath from leaving blank rows upon reordering

    - by coneybeare
    I am having an issue where in reordering my UITableViewCells, the tableView is not scrolling with the cell. Only a blank row appears and any subsequent scrolling gets an Array out of bounds error without any of my code in the Stack Trace. Here is a quick video of the problem. Here is the relevant code: - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return indexPath.section == 1; } - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { BOOL ret = indexPath.section == 1 && indexPath.row < self.count; DebugLog(@"canMoveRowAtIndexPath: %d:%d %@", indexPath.section, indexPath.row, (ret ? @"YES" : @"NO")); return ret; } - (void)delayedUpdateCellBackgroundPositionsForTableView:(UITableView *)tableView { [self performSelectorOnMainThread:@selector(updateCellBackgroundPositionsForTableView:) withObject:tableView waitUntilDone:NO]; } - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath { if (fromIndexPath.row == toIndexPath.row) return; DebugLog(@"Moved audio from %d:%d to %d:%d", fromIndexPath.section, fromIndexPath.row, toIndexPath.section, toIndexPath.row); NSMutableArray *audio = [self.items objectAtIndex:fromIndexPath.section]; [audio exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row]; [self performSelector:@selector(delayedUpdateCellBackgroundPositionsForTableView:) withObject:tableView afterDelay:kDefaultAnimationDuration/3]; } And here is the generated Stack Trace of the crash: Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000002, 0x0000000000000000 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Application Specific Information: iPhone Simulator 3.2 (193.3), iPhone OS 3.0 (7A341) *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray removeObjectsInRange:]: index (6) beyond bounds (6)' Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 CoreFoundation 0x302ac924 ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___ + 4 1 libobjc.A.dylib 0x93cb2509 objc_exception_throw + 56 2 CoreFoundation 0x3028e5fb +[NSException raise:format:arguments:] + 155 3 CoreFoundation 0x3028e55a +[NSException raise:format:] + 58 4 Foundation 0x305684e9 _NSArrayRaiseBoundException + 121 5 Foundation 0x30553a6e -[NSCFArray removeObjectsInRange:] + 142 6 UIKit 0x30950105 -[UITableView(_UITableViewPrivate) _updateVisibleCellsNow] + 862 7 UIKit 0x30947715 -[UITableView layoutSubviews] + 250 8 QuartzCore 0x0090bd94 -[CALayer layoutSublayers] + 78 9 QuartzCore 0x0090bb55 CALayerLayoutIfNeeded + 229 10 QuartzCore 0x0090b3ae CA::Context::commit_transaction(CA::Transaction*) + 302 11 QuartzCore 0x0090b022 CA::Transaction::commit() + 292 12 QuartzCore 0x009132e0 CA::Transaction::observer_callback(__CFRunLoopObserver*, unsigned long, void*) + 84 13 CoreFoundation 0x30245c32 __CFRunLoopDoObservers + 594 14 CoreFoundation 0x3024503f CFRunLoopRunSpecific + 2575 15 CoreFoundation 0x30244628 CFRunLoopRunInMode + 88 16 GraphicsServices 0x32044c31 GSEventRunModal + 217 17 GraphicsServices 0x32044cf6 GSEventRun + 115 18 UIKit 0x309021ee UIApplicationMain + 1157 19 XXXXXXXX 0x0000278a main + 104 (main.m:12) 20 XXXXXXXX 0x000026f6 start + 54 NOte that the array out of bounds length is not the length of my elements (I have 9), but always something smaller.

UPDATE: More code as requested In my delegate: - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { return UITableViewCellEditingStyleNone; } - (NSIndexPath *)tableView:(UITableView *)tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath { int count = [(UAPlaylistEditDataSource *)self.dataSource count]; if (proposedDestinationIndexPath.section == 0) { return [NSIndexPath indexPathForRow:0 inSection:sourceIndexPath.section]; }else if (proposedDestinationIndexPath.row >= count) { return [NSIndexPath indexPathForRow:count-1 inSection:sourceIndexPath.section]; } return proposedDestinationIndexPath; } …thats about it. I am using the three20 framework and I have not had any issues with reordering till now. The problem is also not in the updateCellBackgroundPositionsForTableView: method as it still crashes when this is commented out.

  • CherryPy sessions for same domain, different port

    - by detly
    Consider the script below. It will launch two subprocesses, each one a CherryPy app (hit Ctrl+C or whatever the KeyboardInterrupt combo is on your system to end them both). If you run it with CP 3.0 (taking care to change the 3.0/3.1 specific lines in "StartServer"), then visit: http://localhost:15002/ ...you see an empty dict. Then visit: http://localhost:15002/set?val=10 http://localhost:15002/ ...and you see the newly populated dict. Then visit: http://localhost:15012/ ...and go back to http://localhost:15002/ ...and nothing has changed. If you try the same thing with CP 3.1 (remember the lines in "StartServer"!), when you get to the last step, the dict is now empty. This happens in Windows and Debian, Python 2.5 and 2.6. You can try all sorts of things: changing to file storage, separating the storage paths... the only difference it makes is that the sessions might get merged instead of erased. I've read another post about this as well, and there's a suggestion there to put the session tools config keys in the app config rather than the global config, but I don't think that's relevant to this usage where the apps run independently. What do I do to get independent CherryPy applications to NOT interfere with each other? Note: I originally asked this on the CherryPy mailing list but haven't had a response yet so I'm trying here. I hope that's okay. import os, os.path, socket, sys import subprocess import cgi import cherrypy HTTP_PORT = 15002 HTTP_HOST = "127.0.0.1" site1conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '1', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} site2conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT + 10, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '2', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} class Home(object) : def __init__(self, key): self.key = key @cherrypy.expose def index(self): return """\ <html> <body>Session: <br>%s </body> </html> """ % cgi.escape(str(dict(cherrypy.session))) @cherrypy.expose def set(self, val): cherrypy.session[self.key.upper()] = val return """\ <html> <body>Set %s to %s</body> </html>""" % (cgi.escape(self.key), cgi.escape(val)) def StartServer(conf, key): cherrypy.config.update(conf) print 'Starting server (%s)' % key cherrypy.tree.mount(Home(key), '/', {}) # Start the web server. #### 3.0 # cherrypy.server.quickstart() # cherrypy.engine.start() #### #### 3.1 cherrypy.engine.start() cherrypy.engine.block() #### def Main(): # Start first webserver proc1 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "1"]) proc2 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "2"]) proc1.wait() proc2.wait() if __name__ == "__main__": print sys.argv if len(sys.argv) == 1: # Master process Main() elif(int(sys.argv[1]) == 1): StartServer(site1conf, 'magic') elif(int(sys.argv[1]) == 2): StartServer(site2conf, 'science') else: sys.exit(1)

  • PHP5.3 is not working with MySQL5.1 IIS7 Times out

    - by Thorn007
    I have set up PHP5.3, MySQL5.1, and IIS7 on Window 7 but php doesn't want to work with MySQL. I'm assuming it is a configuration error or an incomplete install on my part. MySQL5.1 is working PHP5.3 is working, phpinfo() shows info and that i have enabled MySQL IIS is setup and using fastCgiModule to run PHP IIS registers php.ini updates port 3306 is firewall free and open to the world php.ini is configured correctly I have added c:\php to the Windows systems PATH In the past I remember moving a file, libmysql.dll, to System32 but I doesn't look like that come with php5.3.1, as the driver comes built in now http://us3.php.net/manual/en/mysqlnd.install.php.

  • SVN naming convention: repository, branches, tags

    - by LookitsPuck
    Hey all! Just curious what your naming conventions are for the following: Repository name Branches Tags Right now, we're employing the following standards with SVN, but would like to improve on it: Each project has its own repository Each repository has a set of directories: tags, branches, trunk Tags are immutable copies of the the tree (release, beta, rc, etc.) Branches are typically feature branches Trunk is ongoing development (quick additions, bug fixes, etc.) Now, with that said, I'm curious how everyone is not only handling the naming of their repositories, but also their tags and branches. For example, do you employ a camel case structure for the project name? So, if your project is something like Backyard Baseball for Youngins, how do you handle that? backyardBaseballForYoungins backyard_baseball_for_youngins BackyardBaseballForYoungins backyardbaseballforyoungins That seems rather trivial, but it's a question. If you're going with the feature branch paradigm, how do you name your feature branches? After the feature itself in plain English? Some sort of versioning scheme? I.e. say you want to add functionality to the Backyard Baseball app that allows users to add their own statistics. What would you call your branch? {repoName}/branches/user-add-statistics {repoName}/branches/userAddStatistics {repoName}/branches/user_add_statistics etc. Or: {repoName}/branches/1.1.0.1 If you go the version route, how do you correlate the version numbers? It seems that feature branches wouldn't benefit much from a versioning schema, being that 1 developer could be working on the "user add statistics" functionality, and another developer could be working on the "admin add statistics" functionality. How are these do branch versions named? Are they better off being: {repoName}/branches/1.1.0.1 - user add statistics {repoName}/branches/1.1.0.2 - admin add statistics And once they're merged into the trunk, the trunk might increment appropriately? Tags seem like they'd benefit the most from version numbers. With that being said, how are you correlating the versions for your project (whether it be trunk, branch, tag, etc.) with SVN? I.e. how do you, as the developer, know that 1.1.1 has admin add statistics, and user add statistics functionality? How are these descriptive and linked? It'd make sense for tags to have release notes in each tag since they're immutable. But, yeah, what are your SVN policies going forward?

  • How to construct a flowchart/storyboard in a Func Spec

    - by PeterQ
    Hey I'm a bit embarrassed to write a post on this topic, but I would appreciate the help. At my school, the CS kids (myself included) have created a nice, little program that is built for incoming Chem/Bio students. It consists of several modules that reviews topics they should have a firm grasp on before they start their classes. It's a nice tool since it cuts down on reviewing the material in class but also allows the students to do a quick diagnostic to fix any problems. Now, I'm in charge of constructing a simple interface that reports on the progress of the group and individual students. The interface is pretty simple. It's just a window that pops up, and it has three tabs: the first tab is a "cumulative" report of all of students. The secnod tab has a drop down box that lists the students and once a student is selected, a report for him/her comes up. And the third tab is simply a description of all of the terms used in the 1st and 2nd tabs. Now, I'm trying to be a good CS student and write a func. spec for my interface. My problem comes with the fact that I'd like to insert a little flowchart using Visio. Problem is, and I'm quite embarrassed to admit this, I don't know how to construct the flowchart/storyboard. For instance, I know I start with a "Start/Click Icon" in a rectangle. Then where do I go? Do I draw three arrrows (one going to each tab) and then describing what goes on? In tab one, the only thing that happens is that the user will select a "sort" method in the drop down box. This will sort the list. The End. Similarly, if the user selects the second tab, then he will go to a drop down box with the student names. Selecting a name will bring up student info. And the third tab is just a list of unfamiliar terms coming from the first or second tab. I wanted to storyboard/flowchart what I'm doing, but I'm unclear how to go about it. Any help would be appreciated! (Just to clarify, I'm not having trouble with using Visio, but I don't know how one goes about construct a storyboard or determining the procedure for constructing one)

  • log4net: what am I doing wrong?

    - by Berryl
    Being a log4net newb / boob I just copied lines from an NHibernate example project where I can see the log.txt file is updated. Is there a quick answer why mine isn't creating the file? Cheers, Berryl [assembly: log4net.Config.XmlConfigurator(Watch = true)] I saw another post here saying this should go in AssemblyInfo, but in the example project this is just another line in a static helper class. Not wanting to 'mess with' assemblyInfo I also put this in a static helper, along with the following to actually log in the same static helper class: private static readonly log4net.ILog _log = log4net.LogManager.GetLogger( System.Reflection.MethodBase.GetCurrentMethod().DeclaringType ); And in app.config, I have <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> </configSections> <!-- This section contains the log4net configuration settings --> <log4net> <!-- Define an output appender (where the logs can go) --> <appender name="LogFileAppender" type="log4net.Appender.FileAppender, log4net"> <param name="File" value="log.txt" /> <param name="AppendToFile" value="false" /> <layout type="log4net.Layout.PatternLayout, log4net"> <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] &lt;%X{auth}&gt; - %m%n" /> </layout> </appender> <appender name="LogDebugAppender" type="log4net.Appender.DebugAppender, log4net"> <layout type="log4net.Layout.PatternLayout, log4net"> <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] &lt;%X{auth}&gt; - %m%n"/> </layout> </appender> <!-- Setup the root category, set the default priority level and add the appender(s) (where the logs will go) --> <root> <priority value="ALL" /> <appender-ref ref="LogFileAppender" /> <appender-ref ref="LogDebugAppender"/> </root> <!-- Specify the level for some specific namespaces --> <!-- Level can be : ALL, DEBUG, INFO, WARN, ERROR, FATAL, OFF --> <logger name="NHibernate"> <level value="ALL" /> </logger> </log4net>

  • How to stop event bubbling with jquery live?

    - by chobo2
    Hi I am trying to stop some events but stopPropagation does not work with "live" so I am not sure what to do. I found this on their site. Live events do not bubble in the traditional manner and cannot be stopped using stopPropagation or stopImmediatePropagation. For example, take the case of two click events - one bound to "li" and another "li a". Should a click occur on the inner anchor BOTH events will be triggered. This is because when a $("li").bind("click", fn); is bound you're actually saying "Whenever a click event occurs on an LI element - or inside an LI element - trigger this click event." To stop further processing for a live event, fn must return false It says that fn must return false so what I tried to do $('.MoreAppointments').live('click', function(e) { alert("Hi"); return false; }); but that did not work so I am not sure how to make it return false. Update Here is some more information. I have a table cell and I bind a click event to it. $('#CalendarBody .DateBox').click(function(e) { AddApointment(this); }); So the AddApointment just makes some ui dialog box. Now the live code(MoreAppointments) sits in this table cell and is basically an anchor tag. So when I click on the anchor tag it first goes to the above code(addApointment - so runs that event first) runs that but does not launch my dialog box instead it goes straight to the (MoreAppointment) event and runs that code. Once that code has run it launches the dialog box from "addApointment". Update 2 Here is some of the html. I did not copy the whole table since it is kinda big and all the cells repeat itself with the same data. If needed I will post it. <td id="c_12012009" class="DateBox"> <div class="DateLabel"> 1</div> <div class="appointmentContainer"> <a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a> </div> <div class="appointmentOverflowContainer"> <div> <a class="MoreAppointments">+1 More</a></div> </div> </td>

  • Streaming Video with Blackberry Simulator

    - by Jenny
    So, I wrote a quick little app for the iphone that takes in an http URL, and plays the .mp4 video located at that URL (it does more than that, of course, but that's the meat of it). Naturally, I wanted to have it on more than just a single mobile platform, so I decided to target Blackberry next. However, I'm running into a lot of problems with the Blackberry Environment. First of all, I learn that I can only download 256k files! I learn how to set that variable in my MDS simulator (and learn that this is NOT a production solution, because any end users will have to have their BES or MDS admin change the setting there). Then, I find a video less than 2 MB I can practice with. Going to the browser prompts me to save the video (rather than it playing in the browser like I expected). After saving the video, it refuses to play, saying it's the wrong format. So. I can't find a reference to IF Blackberry can stream with HTTP (i"ve heard it CAN use RTSP, though, and heard some rumors that it can't use HTTP, which would really suck). I also can't find a reference to what format blackberry uses (although I can find a million programs that will convert one file to the 'blackberry' format). Surely SOMEONE must have tried to stream video with the blackberry before. How did they go about doing so? Is it just a hopeless pipedream? Will I have to go with RTSP? Sorry for the lack of a concrete question...I'm just really lost, and I hate how so many tutorials or forum posts seem to assume I know the capabilities of the Blackberry... Edit: I finally found out that the .3gp (which I'd never heard of ) format is what Blackberry uses. Still have no idea how to stream videos off the web, though. I found a tutorial: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 That seemed to be useful, but the code doesn't work if you give it a URL (even though it claims it does).

  • Django: CharField with fixed length, how?

    - by Giovanni Di Milia
    Hi everybody, I wold like to have in my model a CharField with fixed length. In other words I want that only a specified length is valid. I tried to do something like volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me an error (it seems that I can use both max_length and min_length at the same time). Is there another quick way? Thanks EDIT: Following the suggestions of some people I will be a bit more specific: My model is this: class Volume(models.Model): vid = models.AutoField(primary_key=True) jid = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal") volumenumber = models.CharField('Volume Number') date_publication = models.CharField('Date of Publication', max_length=6, blank=True) class Meta: db_table = u'volume' verbose_name = "Volume" ordering = ['jid', 'volumenumber'] unique_together = ('jid', 'volumenumber') def __unicode__(self): return (str(self.jid) + ' - ' + str(self.volumenumber)) What I want is that the volumenumber must be exactly 4 characters. I.E. if someone insert '4b' django gives an error because it expects a string of 4 characters. So I tried with volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me this error: Validating models... Unhandled exception in thread started by <function inner_run at 0x70feb0> Traceback (most recent call last): File "/Library/Python/2.5/site-packages/django/core/management/commands/runserver.py", line 48, in inner_run self.validate(display_num_errors=True) File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 249, in validate num_errors = get_validation_errors(s, app) File "/Library/Python/2.5/site-packages/django/core/management/validation.py", line 28, in get_validation_errors for (app_name, error) in get_app_errors().items(): File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 131, in get_app_errors self._populate() File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 58, in _populate self.load_app(app_name, True) File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 74, in load_app models = import_module('.models', app_name) File "/Library/Python/2.5/site-packages/django/utils/importlib.py", line 35, in import_module __import__(name) File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 120, in <module> class Volume(models.Model): File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 123, in Volume volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) TypeError: __init__() got an unexpected keyword argument 'min_length' That obviously doesn't appear if I use only "max_length" OR "min_length". I read the documentation on the django web site and it seems that I'm right (I cannot use both together) so I'm asking if there is another way to solve the problem. Thanks again

  • Animating custom-drawn UITableViewCell when entering edit mode

    - by Adam Alexander
    Background First of all, much gratitude to atebits for their very informative blog post Fast Scrolling in Tweetie with UITableView. The post explains in detail how the developers were able to squeeze as much scrolling performance as possible out of the UITableViews in Tweetie. Goals Beginning with the source code linked from the blog post (original) (my github repo): Allow a UITableView using these custom cells to switch to edit mode, exposing the UI for deleting an item from the table. (github commit) Move the cell's text aside as the deletion control slides in from the left. This is complete, although the text jumps back and forth without animation. (github commit) Apply animation to the text movement in goal 2 above for a smooth user experience. This is the step where I became stuck. The Question What is the best way to introduce this animation to complete goal 3? It would be nice if this could be done in a manner that keeps the logic from my last commit because I would love the option to move the conflicting part of the view only, while any non-conflicting portions (such as right-justified text) stay in the same place or move a different number of pixels. If the above is not possible then undoing my last commit and replacing it with an option that slides the entire view to the right would be a workable solution also. I appreciate any help anyone can provide, from quick pointers and ideas all the way to code snippets or github commits. Of course you are welcome to fork my repo if you would like. I will be staying involved with this question to make sure any successful resolution is committed to github and fully documented here. Thanks very much for your time! Updated thoughts I have been thinking about this a lot since my first post and realized that moving some text items relative to others in the view could undo some of the original performance goals solved in the original blog post. So at this point I am thinking a solution where the entire single subview is animated to its new postion may be the best one. Second, if it is done in this way there may be an instance where the subview has a custom color or gradient background. Hopefully this can be done in a way that in its normal position the background extends unseen off to the left enough so that when the view is slid to the right the custom background is still visible across the entire cell.

  • jquery - establishing truths when loading inline javascript via AJAX

    - by yaya3
    I have thrown together a quick prototype to try and establish a few very basic truths regarding what inline JavaScript can do when it is loaded with AJAX: index.html <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> </head> <body> <script type="text/javascript"> $('p').css('color','white'); alert($('p').css('color')); // DISPLAYS FIRST but is "undefined" $(document).ready(function(){ $('#ajax-loaded-content-wrapper').load('loaded-by-ajax.html', function(){ $('p').css('color','grey'); alert($('p').css('color')); // DISPLAYS LAST (as expected) }); $('p').css('color','purple'); alert($('p').css('color')); // DISPLAYS SECOND }); </script> <p>Content not loaded by ajax</p> <div id="ajax-loaded-content-wrapper"> </div> </body> </html> loaded-by-ajax.html <p>Some content loaded by ajax</p> <script type="text/javascript"> $('p').css('color','yellow'); alert($('p').css('color')); // DISPLAYS THIRD $(document).ready(function(){ $('p').css('color','pink'); alert($('p').css('color')); // DISPLAYS FOURTH }); </script> <p>Some content loaded by ajax</p> <script type="text/javascript"> $(document).ready(function(){ $('p').css('color','blue'); alert($('p').css('color')); // DISPLAYS FIFTH }); $('p').css('color','green'); alert($('p').css('color')); // DISPLAYS SIX </script> <p>Some content loaded by ajax</p> Notes: a) All of the above (except the first) successfully change the colour of all the paragraphs (in firefox 3.6.3). b) I've used alert instead of console.log as console is undefined when called in the 'loaded' HTML. Truths(?): $(document).ready() does not treat the 'loaded' HTML as a new document, or reread the entire DOM tree including the loaded HTML JavaScript that is contained inside 'loaded' HTML can effect the style of existing DOM nodes One can successfully use the jQuery library inside 'loaded' HTML to effect the style of existing DOM nodes One can not use the firebug inside 'loaded' HTML can effect the existing DOM (proven by Note a) Am I correct in deriving these 'truths' from my tests (test validity)? If not, how would you test for these?

  • Why does filter: blur(0) still cause text to blur under Webkit?

    - by johnkavanagh
    I've come across a bug today that's taken far longer than I would like to admit to identify. Essentially: setting a filter: blur(0) (or the vendor-specific -webkit-filter) on an element should - I believe - mean that no form of blur is applied. However, having tested this today, it would appear that Webkit based browsers still blur the text within any element with either blur(0) or blur(0px) assigned to it. I've knocked together a quick Fiddle here: http://jsfiddle.net/f9rBE/ These are three identical dixs containing text (no custom fonts): This has absolutely nothing assigned Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aliquam facilisis orci in quam venenatis, in tempus ipsum sagittis. Suspendisse potenti. Donec ullamcorper lacus vel odio accumsan, vel aliquam libero tempor. Praesent nec libero venenatis, ultrices arcu non, luctus quam. Morbi scelerisque sit amet turpis sit amet tincidunt. Praesent semper erat non purus pretium consequat. Aenean et iaculis turpis. Curabitur diam tellus, consectetur non massa et, commodo venenatis metus. One has no styles at all assigned, the other two have blur(0) and blur(0px): .no-blur{} .zero-px-blur{ -webkit-filter: blur(0px); -moz-filter: blur(0px); -o-filter: blur(0px); -ms-filter: blur(0px); filter: blur(0px); } .zero-blur{ -webkit-filter: blur(0); -moz-filter: blur(0); -o-filter: blur(0); -ms-filter: blur(0); filter: blur(0); } If you preview this under Chrome/Safari you'll see that the text in the second two are still blurred: A few things worth noting: This unintentional blurring occurs in Safari on iOS7 devices (both iPhones and iPads); It also occurs on Chrome and Safari under OSX; It doesn't happen under FireFox in OSX. Of course, this isn't supported at all in Firefox just yet so it's hard to tell whether the behaviour I'm seeing is intentional/expected behaviour, or whether this is a bug in Webkit? Is it possible that this is only prevalent in higher-density resolution devices (ie: retina MacBook/iPhone/iPad)? With this in mind, how do you actually overwrite an item that has blur applied to it to set it back to non-blurred?

  • iPad: Tables in Popover Views do not Scroll to Show Selected Row

    - by mahboudz
    I am having two problems with viewcontrollerss in landscape orientation on the iPad. (1) I have two popups which hold tables. The tables should scroll to a specific row to reflect a selection in the main view. Instead, the tables do scroll down some but the actual selected row remains off screen. (2) All my action sheets come up with a width of 320. In Interface Builder, all my views are created in landscape orientation. Only the main Window is not, but I don't see a way to change that. My Configuration: Upon launch, I get the following coordinates for my main window and the main viewcontroller view: Window frame {{0, 0}, {768, 1024}} mainView frame {{0, 0}, {748, 1024}} All other views after that show these coordinates when summoned (when loaded but before being presented): frame of keysig {{0, 0}, {1024, 768}} frame of instrumentSelect {{20, 0}, {1024, 768}} frame of settings {{0, 0}, {467, 300}} In all my viewControllers, i respond to shouldAutorotateToInterfaceOrientation with: return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight)); Everything (almost) functions as expected. The app launches into one of the two landscape modes. The views (and viewcontrollers) display everything where it belongs and taps work all across the screen as expected. However, I still have the two problems. Problem 1: I have two popups containing tables long enough to run off screen. The tables should scroll to a selected row. They do scroll i.e. they don't start visually at row 1 but they don't scroll enough to actually show the selected row. It almost seems like a UITable internal rect gets created with the wrong number and stays that way but I've checked both of the UITableView's scrollView content coordinates and they seemed reasonable. Problem 2: I think this is related to problem 1 because my actionsheets come up with a width of 320. I can only assume that the iPad allows actionSheets in only 320 or 480 widths and since it somehow thinks that the screen is oriented in portrait mode, it uses the narrower width. There you have it. I can't believe I am still getting hung up on orientation issues. I swear Apple doesn't make it easy to have a landscape app. Any ideas?

  • iPhone MailComposer class UIViewController dismissModalViewControllerAnimated issues

    - by Scott Pendleton
    I created a class to launch the MailComposer so that my iPhone app would only have one place to go when generating various kinds of e-mail: some with attachments, some not. Some with pre-filled addresses, some not. I didn't want my class implement UIViewController, but it has to so it can be the delegate for the MailComposer. Otherwise, the view controllers that call my class would themselves have to be delegates for the MailComposer, which defeats the purpose. The downside of having my class be a view controller is that it has to load to the screen before it can modally bring up the MailComposer. Unfortunately, view controllers can't be transparent. The effect is, whatever is on screen gets covered by a solid white view controller for a moment before the MailComposer appears. I could maybe live with that, but not this: after the MailComposer goes away, I'm left with my blank view controller occupying the screen. I ought to be able to get rid of it from within itself by calling this: [self.parentViewController dismissModalViewControllerAnimated:NO]; But that dies a horrible death: "Loading 43365 stack frames..." Has my class -- a UIViewController that pre-fills and then launches a MailComposer -- lost track of its parentViewController? It isn't nil, because I've tested for that. As launched from within the current view controller... // My class is called Email. Email *oEmail = [[[Email alloc] init] retain]; // Red, to remind myself that I'd like to someday learn to make it transparent. oEmail.view.backgroundColor = [UIColor redColor]; // Pre-fill whatever fields you want, and specify attachments. oEmail.EmailSubject = @"I am truly stumped"; // This has to go on screen first. [self presentModalViewController:oEmail animated:NO]; // Then this can happen, which brings up the MailComposer. [oEmail f_SendEmail]; // Commenting out the next line didn't help, so I turned it back on. [oEmail release]; Inside the class, you need the mailComposeController:didFinishWithResult:error: method to make the MailComposer go away, and for that to happen, the class has to be the MFMailComposeViewControllerDelegate. Here's what happens in there: // This gets rid of the mail composer. [self dismissModalViewControllerAnimated:YES]; // This never fails to get rid of other modal view controllers when called // from within those controllers, but boy does it not work here. [self.parentViewController dismissModalViewControllerAnimated:NO]; If you can help me, I will be truly thankful!

  • CSS Background-Images Loading after HTML Images (Involves Javascript)

    - by Kevin C.
    I threw together a quick little microsite that you can see at http://monterraauction.com. If you don't have a super-fast connection (and nothing's cached), the very last items to load are the background-images that are used for CSS image-text replacement (primarily, that h1#head at the top, with a 7kb background image). Nothing debilitating, but it looks slightly awkward. And I'm asking this question as a matter of curiosity more than anything else ;) Also, please note that this occurs in Firefox, but not Chrome. Now, underneath the h1#head I have a jquery.cycle.lite-powered slideshow in div#photo. In the HTML markup there are a total of 13, heavy image files that make up each of the slides. If I remove all but the first slide, then the problem goes away! So the CSS background-images are loading after...those HTML images are done? But here's what's confusing: I check it out in YSlow...the CSS background-images have a much lower response time than all of the slides in #photo. Right after all the JS files finish loading, in fact. So why aren't they showing up first? I tried $('#photo img:last-child').load(function() { alert('Locked and Loaded!')});, but the background-images pop up a while before the alert does, so I'm assuming it's not waiting until the last slide has loaded (admittedly I'm a bit of JS noob so maybe I'm just making a wrong assumption). I also tried commenting out all the jquery.cycle.lite stuff, so that I knew I didn't have any JS manipulating the DOM elements in #photo, but that wasn't the problem. I tried putting all the JS at the bottom of the document, right before </body>, but that didn't work. Lastly, I tried turning off javascript, and of course the css background-image loads way before the images in #photo, so it's definitely a JS thing (amirite?) I guess the obvious solution here is to mark the slides up as LINKS rather than IMGs, and have Javascript insert those 12 extra slideshow images after the DOM is ready--users without javascript shouldn't need to download the extra images anyways. But again, I'm curious: Why does removing the extra HTML images from within #photo solve the problem? And why are the CSS background-images showing up after the HTML images have loaded, even though YSlow says the css background-images loaded first? Seeing as how it happens in FF but not Chrome, is it simply a browser issue? I appreciate any insight you guys could give me!

  • Run word on server for COM to work??

    - by chupinette
    I got this from php.net website. This is related to the problem I am having with tho code below. Can anyone explain me what the following does. I am using Vista. What does running Word on server implies? In order to get the Word example running, do the following on the server side. Worked for me... 1. Click START--RUN and enter "dcomcnfg" 2. In the "Applications" tab, go down to "Microsoft Word Document" 3. Click PROPERTIES button 4. Go to the "Security" Tab 5. Click "Use custom access permissions", and then click EDIT 6. Click ADD and then click SHOW USERS 7. Highlight the IIS anonymous user account (usually IUSR_), click ADD 8. Go back to the "Security" tab by hitting OK 9. Click "Use custom launch permissions", and the click EDIT 10. Click ADD and then click SHOW USERS 11. Highlight the IIS anonymous user account (usually IUSR_), click ADD 12. Hit OK, and then hit APPLY. Also, you should look at the "Identity" tab in the Microsoft Word Document PROPERTIES and see that it is set to "Interactive User" ALSO, log into the machine AS the IUSR_ account, start word, and make sure to click through the dialog boxes that Word shows the first time it is run for a certain user. In other words, make sure Word opens cleanly for the IUSR_ user. <?php // starting word $word = new COM("word.application") or die("Unable to instantiate Word"); echo "Loaded Word, version {$word->Version}\n"; //bring it to front $word->Visible = 1; //open an empty document $word->Documents->Add(); //do some weird stuff $word->Selection->TypeText("This is a test..."); $word->Documents[1]->SaveAs("Useless test.doc"); //closing word $word->Quit(); //free the object $word = null; ?>

  • Accessible semantic jQuery tabs plugin

    - by user249950
    Hello, Just a quick question to see if anyone knows of any jquery tabs plugins that run based on a similar structure to: <div class="tabs"> <div> <h4>Tab one</h4> <p>Lorem Ipsum</p> </div> <div> <h4>Tab two</h4> <p>Lorem Ipsum</p> </div> </div> Where the plugin grabs the title of the tabs from the h4s? I can only seem to find plugins that use the structure: <div id="tabs"> <ul> <li><a href="#tabs-1">Nunc tincidunt</a></li> <li><a href="#tabs-2">Proin dolor</a></li> <li><a href="#tabs-3">Aenean lacinia</a></li> </ul> <div id="tabs-1"> <p>Tab 1 content</p> </div> <div id="tabs-2"> <p>Tab 2 content</p> </div> <div id="tabs-3"> <p>Tab 3 content</p> </div> </div> I assume the only other way to use these plugins would be to grab the titles, remove them, add them into a list at the top of the html and then run the plugin based on that? I just ask as I am quite new to jQuery so I'm not sure how I would go about it and just wondered if there was a plugin already in existence that anyone knew of. If not, not to worry, I'll have to get busy with the docs and give it a go! Cheers
