  • How can I use PHP Mail() function within PHP-FPM? On Nginx?

    - by TheBlackBenzKid
    I have searched everywhere for this and I really want to resolve this. In the past I just end up using an SMTP service like SendGrid for PHP and a mailing plugin like SwiftMailer. However I want to use PHP. Basically my setup (I am new to server setup, and this is my personal setup following a tutorial) Nginx Rackspace Cloud PHP 5.3 PHP-FPM Ubuntu 11.04 My phpinfo() returns this about the Mail entries: mail.log no value mail.add_x_header On mail.force_extra_parameters no value sendmail_from no value sendmail_path /usr/sbin/sendmail -t -i SMTP localhost smtp_port 25 Can someone help me to as why Mail() will not work - my script is working on all other sites, it is a normal mail command. Do I need to setup logs or enable some PHP port on the server? My Sample script <? # FORMS VARS // $to = $customers_email; // $to = $customers_email; $to = $_GET["customerEmailFromForm"]; $subject = "Thank you for contacting Real-Domain.com"; $message = " <html> <head> </head> <body> Thanks, your message was sent and our team will be in touch shortly. <img src='http://cdn.com/emails/thank_you.jpg' /> </body> </html> "; $headers = "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n"; $headers .= 'From: <[email protected]>' . "\r\n"; // SEND MAIL mail($to,$subject,$message,$headers); ?> Thanks

  • Converting a pointer for a base class into an inherited class

    - by Shawn B
    Hey, I'm working on a small roguelike game, and for any object/"thing" that is not a part of the map is based off an XEntity class. There are several classes that depend on it, such as XPlayer, XItem, and XMonster. My problem is, that I want to convert a pointer from XEntity to XItem when I know that an object is in item. The sample code I am using to pick up an item is this, it is when a different entity picks up an item it is standing over. void XEntity::PickupItem() { XEntity *Ent = MapList; // Start of a linked list while(true) { if(Ent == NULL) { break; } if(Ent->Flags & ENT_ITEM) { Ent->RemoveEntity(); // Unlink from the map's linked list XItem *Item = Ent // Problem is here, type-safety // Code to link into inventory is here break; } Ent = Ent->MapList; } } My first thought was to create a method in XEntity that returns itself as an XItem pointer, but it creates circular dependencies that are unresolvable. I'm pretty stumped about this one. Any help is greatly appreciated.

  • UITextField inside of UITableViewCell will not activate on iPad but works on iPhone

    - by cfihelp
    I have a UITextField inside a UITableViewCell. It will not activate on the iPad (but it works fine on the iPhone) no matter what I try. Tapping on it and telling it to become the firstResponder both fail. The odd thing is that if I take the exact same code and move it to another view controller in my app it executes just fine. This makes it seem as if there is likely a problem in the parent UITableViewController but I can't find anything obvious. I'm hoping that someone out there has experienced a similar problem and can point me in the right direction. Below is the sample code that works fine when I move it to a new project or put it in a new view controller launched immediately by my app delegate: // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } if (indexPath.row == 0) { UITextField *nameText = [[UITextField alloc] initWithFrame:CGRectMake(5, 5, cell.contentView.frame.size.width, cell.contentView.frame.size.height)]; nameText.delegate = self; nameText.backgroundColor = [UIColor redColor]; [cell.contentView addSubview:nameText]; [nameText becomeFirstResponder]; [nameText release]; } // Configure the cell... return cell; } Help!

  • CSS Hover on parent list Item only

    - by Daniel O'Connor
    Hey Everyone, So I have some nested lists (only one level deep) and I'm running into trouble with the CSS :hover feature. I only want the hover to apply to the parent class, but I can't figure that one out. Here's my CSS <style type="text/css" media="screen"> .listblock li img { visibility: hidden; } .listblock li:hover img { visibility: visible; } </style> And here is a sample of one of the lists. <ul> <li>One <a href="#"><img src="img/basket.png" height="16" width="16" alt="Buy" class="buy" onClick="pageTracker._trackEvent('Outbound Links', 'Amazon');"/></a></li> <li>Two <a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a> <ul> <li>Uno<a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a></li> <li>Dos <a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a></li> </ul> </li> <li>Three <a href="#"><img src="img/basket.png" height="16" width="16" alt="Buy" class="buy" onClick="pageTracker._trackEvent('Outbound Links', 'Amazon');"/></a></li> </ul> The problem is that the image in the Uno and Dos list items also hovers. :( Help please! Thanks a lot

  • Triangle numbers problem....show within 4 seconds

    - by Daredevil
    The sequence of triangle numbers is generated by adding the natural numbers. So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28. The first ten terms would be: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ... Let us list the factors of the first seven triangle numbers: 1: 1 3: 1,3 6: 1,2,3,6 10: 1,2,5,10 15: 1,3,5,15 21: 1,3,7,21 28: 1,2,4,7,14,28 We can see that 28 is the first triangle number to have over five divisors. Given an integer n, display the first triangle number having at least n divisors. Sample Input: 5 Output 28 Input Constraints: 1<=n<=320 I was obviously able to do this question, but I used a naive algorithm: Get n. Find triangle numbers and check their number of factors using the mod operator. But the challenge was to show the output within 4 seconds of input. On high inputs like 190 and above it took almost 15-16 seconds. Then I tried to put the triangle numbers and their number of factors in a 2d array first and then get the input from the user and search the array. But somehow I couldn't do it: I got a lot of processor faults. Please try doing it with this method and paste the code. Or if there are any better ways, please tell me.

  • Images not responsive although in responsive container

    - by Darren Sweeney
    I have the following: <div id="hp_imgs"> <img src="/images/hp/1.jpg"> <img src="/images/hp/2.jpg"> <img src="/images/hp/3.jpg"> <img src="/images/hp/4.jpg"> <img src="/images/hp/5.jpg"> <img src="/images/hp/6.jpg"> <img src="/images/hp/7.jpg"> <img src="/images/hp/8.jpg"> </div> The images were sized when created to form a grid of sorts, so need to be in the order where they are. Consequently, when/if the page is resized I want the images to resize and stay where they are. Here's what I'm trying but images are simply staying the same size and not resizing: #hp_imgs { width:66%; float:left; } #hp_imgs img { float:left; margin:2px; border-radius:4px; display: block; max-width:100%; height:100%; } Is there a better/different way to achieve this?

  • How to identify HTML elements (in javascript) in a browser agnostic fashion

    - by gatapia
    Hi All, I need to identify all html elements on a page in a browser agnostic fashion. What I am basically doing is using mouse events to record clicks on the page. I need to record which element was clicked. So I add a mouse down listener to the document.body element. And on mouse down I get the element under the mouse. Lets say its a div. I then use the index of that div inside the document.getElementsByTagName('*') nodelist and the nodeName ('div') to identify that div. A sample element id would be div45 which means its a div and its the 45th element in the '*' nodelist. This is all fine and good until I use IE which gives me different indexes. So div45 in FireFox may be div47 in IE. Anyone have any ideas? I just need the id of all elements on the page to be the same in any browser, perhaps indexing is not good enough but I really don't have any more ideas. Thanks Guido

  • Delphi Shell IExtractIcon usage and result

    - by Roy M Klever
    What I do: Try to extract thumbnail using IExtractImage if that fail I try to extract icons using IExtractIcon, to get maximum iconsize, but IExtractIcon gives strange results. Problem is I tried to use a methode that extracts icons from an imagelist but if there is no large icon (256x256) it will render the smaller icon at the topleft position of the icon and that does not look good. That is why I am trying to use the IExtractIcon instead. But icons that show up as 256x256 icons in my imagelist extraction methode reports icon sizes as 33 large and 16 small. So how do I check if a large (256x256) icon exists? If you need more info I can provide som sample code. if PThumb.Image = nil then begin OleCheck(ShellFolder.ParseDisplayName(0, nil, StringToOleStr(PThumb.Name), Eaten, PIDL, Atribute)); ShellFolder.GetUIObjectOf(0, 1, PIDL, IExtractIcon, nil, XtractIcon); CoTaskMemFree(PIDL); bool:= False; if Assigned(XtractIcon) then begin GetLocationRes := XtractIcon.GetIconLocation(GIL_FORSHELL, @Buf, sizeof(Buf), IIdx, IFlags); if (GetLocationRes = NOERROR) or (GetLocationRes = E_PENDING) then begin Bmp := TBitmap.Create; try OleCheck(XtractIcon.Extract(@Buf, IIdx, LIcon, SIcon, 32 + (16 shl 16))); Done:= False; Roy M Klever

  • Trying to 'Make' CUDA SDK, ld cannot find library, ldconfig says it can.

    I know there are many other questions similar to this one, but none of the solutions posited there are working for me Basically, making the SDK sample files, i get /usr/bin/ld: cannot find -lcuda which would be an easy enough 'find the library and throw it to ldconfig', except ldconfig already says it has it... $ sudo ldconfig -v | grep cuda /usr/local/cuda/lib64: libcudartemu.so.3 -> libcudartemu.so.3.0.14 libcudart.so.3 -> libcudart.so.3.0.14 /usr/local/cuda/lib: libcudartemu.so.3 -> libcudartemu.so.3.0.14 libcudart.so.3 -> libcudart.so.3.0.14 libcuda.so.1 -> libcuda.so.195.36.15 libcuda.so.1 -> libcuda.so.195.36.15 libicudata.so.42 -> libicudata.so.42.1 And I checked, there is a symlink libcuda.so -> libcuda.so.1 but I'm still confused as to why libcuda.so -> ... doesnt show up I must be missing something really obvious. Any ideas?

  • Table valued function only returns CLR error

    - by Anthony
    I have read-only access to a database that was set up for a third-party, closed-source app. Once group of (hopefully) useful table functions only returns the error: Failed to initialize the Common Language Runtime (CLR) v2.0.50727 with HRESULT 0x80131522. You need to restart SQL server to use CLR integration features. (severity 16) But in theory, the third-party app should be able to use the function (either directly or indirectly), so I'm convinced I'm not setting things up right. I'm very new to SQL Server, so I could be missing something obvious. Or I could be missing something really slight, I have no idea. Here is an example of a query that returns the above error: SELECT * FROM dbo.UncompressDataDateRange(4,'Apr 24 2010 12:00AM','Apr 30 2010 12:00AM') Where the function takes three parameters: The Data Set (int) -- basically the data has 6 classifications, and the giant table this should be pulling from has a column to indicate which is which. startDate (smalldatetime) endDate (smalldatetime) There are other, similar functions that expand on the same idea, all returning the same error. Quick Note: I'm not sure if this is relevant, but I was able to connect to the database via SQL Studio (but without the privs to script the functions as code), and a checked the dependency for the above sample function. It turns out that it is a dependent of a view that I have gotten to work, and that view is dependent of the larger, much-hairier data-table. This makes me think I should somehow be pointing the function at the results of the view, but I'm not seeing any documentation that shows how that is done.

  • Crashing when pushing a XIB based view controller onto navigation controller stack

    - by Michael
    I was attempting to clean up the implementation for a sub-panel on a navigation controller stack, so that the navigation bar could be customized in the XIB instead of doing it manually in the viewDidLoad method. The original (working) setup had the XIB set up with the "File's Owner" class set to the view controller class, and then the view at the top level. This works fine. In the "Interface Builder User Guide", p. 71, it describes the recommended way to build the XIBs for sub-panels ("additional navigation levels"). This approach leaves the "File's Owner" class as NSObject, but adds a UIViewController at the top level, and nests the view (and navigation item) underneath it. The UIViewController's view automatically gets connected to the contained view. When I try to push the controller init'd with this new XIB, the app crashes because of a missing view: SettingsViewController *controller = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; 2010-04-23 11:17:37.135 xxxx[1173:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsTestView" nib but the view outlet was not set.' I've double checked everything, and tried building a clean XIB from scratch, but get the same result. I looked through a number of the code sample projects, and NONE of them use the documented/recommended approach--they all use the File's Owner class and manually set up the navigation bar in viewDidLoad like I originally had it. Is it possible to get it working the "recommended" way? Thanks! Michael

  • NSMutableObject from existing custom class

    - by A.S.
    Hello there. I have an existing class that has methods to deserialise from XML in my code. Now I need to create correct CoreData model from that class. It's objects will be created not only from CoreData storage but also by deserializing XML (somehow like instance->title = [[NSString stringWithUTF8String: (const char *)subNode->children->content] retain; ) without saving to CoreData, and sometimes I need to save it. What is the correct steps to modify existing class to do that except of adding CoreData framework and making my class an NSManagedObject instead of NSObject? Class sample: @interface TSTSong : NSManagedObject<NTSerializableObject> { NSString *identifier; NSString *title; float length; NSURL *previewURL; NSString *author; NSURL *coverURL; NSString *appStoreId; BOOL isPurchased; NSURL *bannerURL; NSDecimalNumber *priceValue; NSLocale *priceLocale; } P.S. I'm noob, so I'f I'm doing smth. wrong - please let me know. Sorry for my english.

  • SQL Server: Output an XML field as tabular data using a stored procedure

    - by Pawan
    I am using a table with an XML data field to store the audit trails of all other tables in the database. That means the same XML field has various XML information. For example my table has two records with XML data like this: 1st record: <client> <name>xyz</name> <ssn>432-54-4231</ssn> </client> 2nd record: <emp> <name>abc</name> <sal>5000</sal> </emp> These are the two sample formats and just two records. The table actually has many more XML formats in the same field and many records in each format. Now my problem is that upon query I need these XML formats to be converted into tabular result sets. What are the options for me? It would be a regular task to query this table and generate reports from it. I want to create a stored procedure to which I can pass that I need to query "<emp>" or "<client>", then my stored procedure should return tabular data.

  • Python: deleting rows in a text file

    - by Jenny
    A sample of the following text file i have is: > 1 -4.6 -4.6 -7.6 > > 2 -1.7 -3.8 -3.1 > > 3 -1.6 -1.6 -3.1 the data is separated by tabs in the text file and the first column indicates the position. I need to iterate through every value in the text file apart from column 0 and find the lowest value. once the lowest value has been found that value needs to be written to a new text file along with the column name and position. Column 0 has the name "position" Column 1 "fifteen", column 2 "sixteen" and column 3 "seventeen" for example the lowest value in the above data is "-7.6" and is in column 3 which has the name "seventeen". Therefore "7.6", "seventeen" and its position value which in this case is 1 need to be written to the new text file. I then need a number of rows deleted from the above text file. E.G. the lowest value above is "-7.6" and is found at position "1" and is found in column 3 which as the name "seventeen". I therefore need seventeen rows deleted from the text file starting from and including position 1 so the the column in which the lowest value is found denotes the amount of rows that needs to be deleted and the position it is found at states the start point of the deletion

  • Reading a large file into Perl array of arrays and manipulating the output for different purposes

    - by Brian D.
    Hello, I am relatively new to Perl and have only used it for converting small files into different formats and feeding data between programs. Now, I need to step it up a little. I have a file of DNA data that is 5,905 lines long, with 32 fields per line. The fields are not delimited by anything and vary in length within the line, but each field is the same size on all 5905 lines. I need each line fed into a separate array from the file, and each field within the line stored as its own variable. I am having no problems storing one line, but I am having difficulties storing each line successively through the entire file. This is how I separate the first line of the full array into individual variables: my $SampleID = substr("@HorseArray", 0, 7); my $PopulationID = substr("@HorseArray", 9, 4); my $Allele1A = substr("@HorseArray", 14, 3); my $Allele1B = substr("@HorseArray", 17, 3); my $Allele2A = substr("@HorseArray", 21, 3); my $Allele2B = substr("@HorseArray", 24, 3); ...etc. My issues are: 1) I need to store each of the 5905 lines as a separate array. 2) I need to be able to reference each line based on the sample ID, or a group of lines based on population ID and sort them. I can sort and manipulate the data fine once it is defined in variables, I am just having trouble constructing a multidimensional array with each of these fields so I can reference each line at will. Any help or direction is much appreciated. I've poured over the Q&A sections on here, but have not found the answer to my questions yet. Thanks!! -Brian

  • Multhreading in Java

    - by Vijay Selvaraj
    I'm working with core java and IBM Websphere MQ 6.0. We have a standalone module say DBcomponent that hits the database and fetches a resultset based on the runtime query. The query is passed to the application via MQ messaging medium. We have a trigger configured for the queue which invokes the DBComponent whenever a message is available in the queue. The DBComponent consumes the message, constructs the query and returns the resultset to another queue. In this overall process we use log4j to log statements on a log file for auditing. The connection is pooled to the database using Apache pool. I am trying to check whether the log messages are logged correctly using a sample program. The program places the input message to the queue and checks for the logs in the log file. Its expected for the trigger method invocation to complete before i try to check for the message in log file, but every time my program to check for log message gets executed first leading my check to failure. Even if i introduce a Thread.sleep(time) doesn't solves the case. How can i make it to keep my method execution waiting until the trigger operation completes? Any suggestion will be helpful.

  • does anyone know of good delphi docking components?

    - by X-Ray
    we'd like to add movable panels to an application. presently we've used DevExpress docking library but have found them to be disappointingly quirky & difficult to work with. it also has some limitations that aren't so great. auto-hide, pinning, and moving of pages by drag-and-drop are all features we'd like to use. the built-in delphi docking doesn't seem to be full-featured enough to do the things we need (also see sample below). perhaps i should dig deeper into delphi's docking abilities...my initial impression is that they seem very toolbar-oriented rather than something i can drop a frame into. i'm not experienced at docking topics. my only experience has been with the DevExpress docking library where i needed to programmatically create & dock panels. is it my imagination or are DevExpress's products unduly difficult to use/learn? the DevExpress Ribbon Bar component compared to the d2009 Ribbon Bar was certainly a useful experience. i will migrate to the d2009 Ribbon Bar as soon as convenient to do so. it was refreshingly straight-forward to learn and use. a sharp contrast compared to the DevExpress equivalent. if it takes 4x as longer to make it using the DevExpress equivalent, it's time to change direction. what would you suggest in regard to the docking library? thank you for your suggestions/comments!

  • Textually diffing JSON

    - by Richard Levasseur
    As part of my release processes, I have to compare some JSON configuration data used by my application. As a first attempt, I just pretty-printed the JSON and diff'ed them (using kdiff3 or just diff). As that data has grown, however, kdiff3 confuses different parts in the output, making additions look like giant modifies, odd deletions, etc. It makes it really hard to figure out what is different. I've tried other diff tools, too (meld, kompare, diff, a few others), but they all have the same problem. Despite my best efforts, I can't seem to format the JSON in a way that the diff tools can understand. Example data: [ { "name": "date", "type": "date", "nullable": true, "state": "enabled" }, { "name": "owner", "type": "string", "nullable": false, "state": "enabled", } ...lots more... ] The above probably wouldn't cause the problem (the problem occurs when there begin to be hundreds of lines), but thats the gist of what is being compared. Thats just a sample; the full objects are 4-5 attributes, and some attributes have 4-5 attributes in them. The attribute names are pretty uniform, but their values pretty varied. In general, it seems like all the diff tools confuse the closing "}" with the next objects closing "}". I can't seem to break them of this habit. I've tried adding whitespace, changing indentation, and adding some "BEGIN" and "END" strings before and after the respective objects, but the tool still get confused.

  • How do I simulate "Is In" using Linq2Sql

    - by flipdoubt
    I often find myself with a list of disconnected Linq2Sql objects or keys that I need to re-select from a Linq2Sql data-context to update or delete in the database. If this were SQL, I would use IS IN in the SQL WHERE clause, but I am stuck with what to do in Linq2Sql. Here is a sample of what I would like to write: public void MarkValidated(IList<int> idsToValidate) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate).ToList(); foreach(var item in items) item.Validated = DateTime.Now; _Db.SubmitChanges(); } // Disposes of DataContext } Or: public void DeleteItems(IList<int> idsToDelete) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate); _Db.Items.DeleteAllOnSubmit(items); _Db.SubmitChanges(); } // Disposes of DataContext } Can I get this done in one trip to the database? If so, how? Is it possible to send all those ints to the database as a list of parameters and is that more efficient than doing a foreach over the list to select each item one at a time?

  • CascadingDropDown taking two parameters...

    - by WeeShian
    I have a page with 3 dropdownlist, 2nd and 3rd dropdownlist are added with CascadingDropDown. 3rd dropdownlist will take parameters from 1st and 2nd dropdownlist. So, in current example for CascadingDropDown i have found from google, they are only passing one parameter to the WebService method. How can pass two parameters to the service method, so that my 3rd dropdownlist will based on the SelectedValue of 1st and 2nd dropdownlist? <WebMethod()> _ Public Function GetTeams(ByVal knownCategoryValues As String, ByVal category As String) As CascadingDropDownNameValue() Dim strConnection As String = ConfigurationManager.ConnectionStrings("nerdlinessConnection").ConnectionString Dim sqlConn As SqlConnection = New SqlConnection(strConnection) Dim strTeamQuery As String = "SELECT * FROM TEAM WHERE conf_id = @confid" Dim cmdFetchTeam As SqlCommand = New SqlCommand(strTeamQuery, sqlConn) Dim dtrTeam As SqlDataReader Dim kvTeam As StringDictionary = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues) Dim intConfId As Integer If Not kvTeam.ContainsKey("Conference") Or Not Int32.TryParse(kvTeam("Conference"), intConfId) Then Return Nothing End If cmdFetchTeam.Parameters.AddWithValue("@confid", intConfId) Dim myTeams As New List(Of CascadingDropDownNameValue) sqlConn.Open() dtrTeam = cmdFetchTeam.ExecuteReader While dtrTeam.Read() Dim strTeamName As String = dtrTeam("team_name").ToString Dim strTeamId As String = dtrTeam("team_id").ToString myTeams.Add(New CascadingDropDownNameValue(strTeamName, strTeamId)) End While Return myTeams.ToArray End Function This is the sample code i found! As you can see in the code, '@confid' will be passed from 2nd dropdownlist! So, hw do i modify this code to get the selected value from 1st dropdownlist as well??

  • LINQ query code for complex merging of data.

    - by Stacey
    I've posted this before, but I worded it poorly. I'm trying again with a more well thought out structure. Re-writing this a bit to make it more clear. I have the following code and I am trying to figure out the shorter linq expression to do it 'inline'. Please examine the "Run()" method near the bottom. I am attempting to understand how to join two dictionaries together based on a matching identifier in one of the objects - so that I can use the query in this sort of syntax. var selected = from a in items.List() // etc. etc. select a; This is my class structure. The Run() method is what I am trying to simplify. I basically need to do this conversion inline in a couple of places, and I wanted to simplify it a great deal so that I can define it more 'cleanly'. class TModel { public Guid Id { get; set; } } class TModels : List<TModel> { } class TValue { } class TStorage { public Dictionary<Guid, TValue> Items { get; set; } } class TArranged { public Dictionary<TModel, TValue> Items { get; set; } } static class Repository { static public TItem Single<TItem, TCollection>(Predicate<TItem> expression) { return default(TItem); // access logic. } } class Sample { public void Run() { TStorage tStorage = new TStorage(); // access tStorage logic here.

  • Correct use of setEmtpyView in AdapterView

    - by Sebi
    I'm really having trouble using the setEmptyView method. I tried it to implement it in GridView and ListView, but both of them didnt work. Here a sample codeblock: networkGames = (GridView) baseLayer.findViewById(R.id.all_game_grid_network); networkGames.setBackgroundResource(R.drawable.game_border); networkGames.setSelector(R.drawable.game_active_border); networkGames.setOnItemClickListener(new NetworkGameListener()); networkGames.setEmptyView(View.inflate(baseLayer, R.drawable.no_network_games, null)); networkGames.setAdapter(new NetworkAdapter()); The network adapter contains no items: private class NetworkAdapter extends BaseAdapter { /* (non-Javadoc) * @see android.widget.Adapter#getCount() */ @Override public int getCount() { return 0; } /* (non-Javadoc) * @see android.widget.Adapter#getItem(int) */ @Override public Object getItem(int position) { return null; } /* (non-Javadoc) * @see android.widget.Adapter#getItemId(int) */ @Override public long getItemId(int position) { return 0; } /* (non-Javadoc) * @see android.widget.Adapter#getView(int, android.view.View, android.view.ViewGroup) */ @Override public View getView(int position, View convertView, ViewGroup parent) { return null; } } I also tried to call networkGames.setAdapter(null), but this doesnt work either. My emtpyView looks like this: <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <TextView android:text="There are currently no network games available. Start a new one." android:id="@+id/TextView01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center"> </TextView> </LinearLayout> I really don't know what I'm doing wrong. I also read various tutorials, but none of them metnioned any problems.

  • Detecting a Dispose() from an exception inside using block

    - by Augusto Radtke
    I have the following code in my application: using (var database = new Database()) { var poll = // Some database query code. foreach (Question question in poll.Questions) { foreach (Answer answer in question.Answers) { database.Remove(answer); } // This is a sample line that simulate an error. throw new Exception("deu pau"); database.Remove(question); } database.Remove(poll); } This code triggers the Database class Dispose() method as usual, and this method automatically commits the transaction to the database, but this leaves my database in an inconsistent state as the answers are erased but the question and the poll are not. There is any way that I can detect in the Dispose() method that it being called because of an exception instead of regular end of the closing block, so I can automate the rollback? I don´t want to manually add a try ... catch block, my objective is to use the using block as a logical safe transaction manager, so it commits to the database if the execution was clean or rollbacks if any exception occured. Do you have some thoughts on that?

  • m2crypto aes-256-cbc not working against encoded openssl files.

    - by Gary
    $ echo 'this is text' > text.1 $ openssl enc -aes-256-cbc -a -k "thisisapassword" -in text.1 -out text.enc $ openssl enc -d -aes-256-cbc -a -k "thisisapassword" -in text.enc -out text.2 $ cat text.2 this is text I can do this with openssl. Now, how do I do the same in m2crypto. Documentation is lacking this. I looked at the snv test cases, still nothing there. I found one sample, http://passingcuriosity.com/2009/aes-encryption-in-python-with-m2crypto/ (changed to aes_256_cbc), and it will encrypted/descrypt it's own strings, but it cannot decrypt anything made with openssl, and anything it encrypts isn't decryptable from openssl. I need to be able enc/dec with aes-256-cbc as have many files already encrypted with this and we have many other systems in place that also handle the aes-256-cbc output just fine. We use password phrases only, with no IV. So setting the IV to \0 * 16 makes sense, but I'm not sure if this is also part of the problem. Anyone have any working samples of doing AES 256 that is compatible with m2crypto? I will also be trying some additional libraries and seeing if they work any better.
