  • Display radio buttons in prolog xpce

    - by Ben03
    I created a menu with Radio Buttons in XPCE prolog, but my radio buttons are showing on the same line, and I want to have each one on a separate line. My code is the following: new(D, dialog('title')), send(D, size, size(500,500)), send(D, append, new(Op, menu(options, marked))), send(Op, append, option1), send(Op, append, option2), send(Op, append, option3), send(Op, size, size(300,300)), send(D, display, Op, point(100, 40)), send(D, append(new(B1,button(ok, message(D, return, Op?selection))))), send(D, display, B1, point(100, 100)), send(D, append(button(cancel, message(D, return, @nil)))), send(D, default_button(ok)), get(D, confirm, Rval), free(D). Thanks in advance

  • Help modifying QuartzDemo example application

    - by BittenApple
    Can anyone please, oh sweet pain, please take me out of my misery by writing a simple example on how the heck you pass a number (int value) which gets created in 1 .m file to another .m file. In the apple demo application called QuartzDemo, there is a file called QuartzImages.m This file has the following line of code: [CODE]CGPDFPageRef page = CGPDFDocumentGetPage(pdf, 1);[/CODE] Notice the (pdf, 1) in that line. This number should be replaced with an integer variable. Now, there is also a file called MainViewController.m. In that file, there is a method? called -(void)viewDidLoad In that method, I want to assign a number to the integer variable which would replace the damn "1" with whatever number I want. I have been pulling my hair trying to get this done, reading beginning iPhone 3 Development book, dev documentation and God knows what not, without results. Any help would be greatly appreciated... Sigh.

  • How to specify blob type in MS Access?

    - by Firat
    How to specify blob type in MS Access? I have office 2007 installed. I am using jdbc, but this should not matter for the SQL query I am passing. Tried to pass a length to it, or FILE type, did not help. CREATE TABLE mytable ( [integer] INTEGER not null, [string] VARCHAR (255), [datetime] DATETIME, [boolean] BIT, [char] CHAR, [short] SHORT, [double] DOUBLE, [float] FLOAT, [long] LONG, [blob] BLOB, // does not work Primary Key ([integer]) )

  • Referencing other modules in atexit

    - by Dmitry Risenberg
    I have a function that is responsible for killing a child process when the program ends: class MySingleton: def __init__(self): import atexit atexit.register(self.stop) def stop(self): os.kill(self.sel_server_pid, signal.SIGTERM) However I get an error message when this function is called: Traceback (most recent call last): File "/usr/lib/python2.5/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/home/commando/Development/Diploma/streaminatr/stream/selenium_tests.py", line 66, in stop os.kill(self.sel_server_pid, signal.SIGTERM) AttributeError: 'NoneType' object has no attribute 'kill' Looks like the os and signal modules get unloaded before atexit is called. Re-importing them solves the problem, but this behaviour seems weird to me - these modules are imported before I register my handler, so why are they unloaded before my own exit handler runs?

  • Compilation hangs for a class with field double d = 2.2250738585072012e-308

    - by 01es
    I have come across an interesting situation. A coworker committed some changes, which would not compile on my machine neither from the IDE (Eclipse) nor from a command line (Maven). The problem manifested in the compilation process taking 100% CPU and only killing the process would help to stop it. After some analysis the cause of the problem was located and resolved. It turned out be a line "double d = 2.2250738585072012e-308" (without semicolon at the end) in one of the interfaces. The following snipped duplicates it. public class WeirdCompilationIssue { double d = 2.2250738585072012e-308 } Why would compiler hang? A language edge case?

  • BASH: Checking for environment variables

    - by Hamza
    Hi folks, I am trying to check the value of an environment variable and depending on the value do certain things and it works fine as long as the variable is set. When it isn't though I get a whole bunch of errors (as BASH is trying to compare the string I specify with an undefined variable, I guess) I tried implementing an extra check to prevent it happening but no luck. The block of code I am using is: #!/bin/bash if [ -n $TESTVAR ] then if [ $TESTVAR == "x" ] then echo "foo" exit elif [ $TESTVAR == "y" ] then echo "bar" exit else echo "baz" exit fi else echo -e "TESTVAR not set\n" fi And this the output: $ export TESTVAR=x $ ./testenv.sh foo $ export TESTVAR=y $ ./testenv.sh bar $ export TESTVAR=q $ ./testenv.sh baz $ unset TESTVAR $ ./testenv.sh ./testenv.sh: line 5: [: ==: unary operator expected ./testenv.sh: line 9: [: ==: unary operator expected baz My question is, shouldn't 'unset TESTVAR' nullify it? It doesn't seem to be the case... Thanks.

  • Objective-c pointer assignment and reassignment dilema

    - by moshe
    Hi, If I do this: 1 NSMutableArray *near = [[NSMutableArray alloc] init]; 2 NSMutableArray *all = [[NSMutableArray alloc] init]; 3 NSMutableArray *current = near; 4 current = all; What happens to near? At line 3, am I setting current to point to the same address as near so that I now have two variables pointing to the same place in memory, or am I setting current to point to the location of near in memory such that I now have this structure: current - near - NSMutableArray The obvious difference would be the value of near at line 4. If the former is happening, near is untouched and still points to its initial place in memory. If the latter is happening,

  • Region or ItemsSource for large data set in ListBox

    - by Ryan
    I'm having trouble figuring out what the best solution is given the following situation. I'm using Prism 4.1, MEF, and .Net 4.0. I have an object Project that could have a large number (~1000) of Line objects. I'm deciding whether it is better to expose an ObservableCollection<LineViewModel> from my ProjectViewModel and manually create the Line viewmodels there OR set the ListBox as it's own region and activate views that way. I'd still want my LineViewModel to have Prism's shared services (IEventAggregator, etc.) injected, but I don't know how to do that when I manually create the LineViewModel. Any suggestions or thoughts?

  • Transferring binary file from web server to client

    - by Yan Cheng CHEOK
    Usually, when I want to transfer a web server text file to client, here is what I did import cgi print "Content-Type: text/plain" print "Content-Disposition: attachment; filename=TEST.txt" print filename = "C:\\TEST.TXT" f = open(filename, 'r') for line in f: print line Works very fine for ANSI file. However, say, I have a binary file a.exe (This file is in web server secret path, and user shall not have direct access to that directory path). I wish to use the similar method to transfer. How I can do so? What content-type I should use? Using print seems to have corrupted content received at client side. What is the correct method?

  • How do I determine if a property was overriden?

    - by Benjamin
    Hello I am doing a project that where I need to register all the properties, because of the system being so huge it would require a lot of work to register all the properties that i want to be dependent for the purpose of Xaml. The goal is to find all properties that are on the top of the tree. so basically public class A{ public int Property1 { get; set; } } public class B : A{ public int Property2 { get; set; } public virtual int Property3 { get; set; } } public class C : B{ public override int Property3 { get; set; } public int Property4 { get; set; } public int Property5 { get; set; } } The end result would be something like this A.Prorperty1 B.Property2 B.Property3 C.Property4 C.Property5 If you notice I don't want to accept overridden properties because of the way I search for the properties if I do something like this C.Property3 for example and it cannot find it it will check C's basetype and there it will find it. This is what I have so far. public static void RegisterType( Type type ) { PropertyInfo[] properties = type.GetProperties( BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly | BindingFlags.GetProperty | BindingFlags.SetProperty ); if ( properties != null && properties.Length > 0 ) { foreach ( PropertyInfo property in properties ) { // if the property is an indexers then we ignore them if ( property.Name == "Item" && property.GetIndexParameters().Length > 0 ) continue; // We don't want Arrays or Generic Property Types if ( (property.PropertyType.IsArray || property.PropertyType.IsGenericType) ) continue; // Register Property } } } What I want are the following: Public properties, that are not overridden, not static, not private Either get and set properties are allowed They are not an array or a generic type They are the top of the tree ie C class in the example is the highest (The property list example is exactly what I am looking for) They are not an indexer property ( this[index] ) Any help will be much appreciated =).

  • How to unset an ajax loading.

    - by metacortex
    Hi, I have this script which loads external content: <script type="text/javascript"> var http_request = false; function makePOSTRequest(url, parameters) { http_request = false; if (window.XMLHttpRequest) { http_request = new XMLHttpRequest(); if (http_request.overrideMimeType) { http_request.overrideMimeType('text/html'); } } else if (window.ActiveXObject) { try { http_request = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { http_request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} } } if (!http_request) { alert('Cannot create XMLHTTP instance'); return false; } http_request.onreadystatechange = alertContents; http_request.open('POST', url, true); http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http_request.setRequestHeader("Content-length", parameters.length); http_request.setRequestHeader("Connection", "close"); http_request.send(parameters); } function alertContents() { if (http_request.readyState == 4) { if (http_request.status == 200) { result = http_request.responseText; document.getElementById('opciones').innerHTML = result; } else { alert('Hubo un problema con la operación.'); } } } function get(obj) { var poststr = "port_post=" + encodeURI( document.getElementById("port-post").value ); makePOSTRequest('http://www.site.com/inc/metaform.php?opcion='+ encodeURI( document.getElementById("port-post").value ), poststr); } </script> This is the select that retrieves the content: <select name="port_post" id="port-post" onchange="get(this.parentNode);"> <option value="1">Select one...</option> <option value="2">Pear</option> <option value="3">Pineapple</option> </select> And this is the container div: <div id="opciones">Default content</div> All I whish to know is how I can unset the ajax loading when I change the selection to "Select one...". I wish to say, how restoring the Default content once the "Select one..." option is selected.

  • Using JavaScript to render HTML; nothing appearing but values will alert

    - by Jack Roscoe
    Hi, I'm taking some information from some variables I have already defined outside this function to create a html svg text box. Here is the function which is causing me trouble: RenderTextBox:function() { alert('this.x: ' + this.x); alert('this.y: ' + this.y); this.textBox = paper.text(this.x, this.y, this.htmlTextBox); } The alerts works prefectly, and prompt me with the values expected. However, the final line which is supposed to create the text box puts them nowhere to be seen. Does anybody know why? If I replace 'this.x, this.y..' with numerical values in the final line of the function, the text box is placed correctly. It's only when I use the 'this.x' and 'this.y' that I have issues.

  • IEnumerable not null but calling Count() results in Exception

    - by Draak
    I have code that's working beautifully on my development machine, but when deployed to the server is throwing null reference exception. So, I can't step through the code, but I've pinned down the culprit. But now I am puzzled. Here's the code. The question is below. Dim certs = From p In persons _ Select New Certificate( _ p.Value, _ New CertificateData.Seminar(thisEvent.Seminar.Name, _ thisEvent.StartDate.Value, _ thisEvent.EndDate.Value, _ thisEvent.Venue.City, _ thisEvent.Venue.State, _ New CertificateData.Instructor( _ staffMember.Name, _ staffMember.Titles, _ instrSignatPath))) _ With {.CertificateId = p.Key} lblMessage.Text = CStr(certs Is Nothing) lblMessage.Text = lblMessage.Text + "<br />" + CStr(certs.Count()) In the code above persons is a dictionary of custom class, and certs is of IEnumerable type. Now here's the quandary.. The first line that sets the label returns False, so certs is not null. But the second line throws an null reference exception. How is this possible?

  • SQLiteOpenHelper getWritableDatabse() fails with no Exception

    - by Michal K
    I have a very strange problem. It only shows from time to time, on several devices. Can't seem to reproduce it when I want, but had it so many times, that I think I know where I get it. So I have a Loader which connects to sqlite through a singleton SQLiteOpenHelper: try{ Log.i(TAG, "Get details offline / db helper: "+DatabaseHelper.getInstance(getContext())); SQLiteDatabase db=DatabaseHelper.getInstance(this.getContext()).getWritableDatabase(); Log.i(TAG, "Get details offline / db: "+db); //doing some work on the db //... } catch(SQLiteException e){ e.printStackTrace(); return null; } catch(Exception e){ e.printStackTrace(); return null; //trying everything to grab some exception or whatever } My SQLIteOpenHelper looks something like this: public class DatabaseHelper extends SQLiteOpenHelper { private static DatabaseHelper mInstance = null; private static Context mCxt; public static DatabaseHelper getInstance(Context cxt) { //using app context ass suggested by CommonsWare Log.i("DBHELPER1", "cxt"+mCxt+" / instance: "+mInstance); if (mInstance == null) { mInstance = new DatabaseHelper(cxt.getApplicationContext()); } Log.i("DBHELPER2", "cxt"+mCxt+" / instance: "+mInstance); mCxt = cxt; return mInstance; } //private constructor private DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); this.mCxt = context; } @Override public void onCreate(SQLiteDatabase db) { //some tables created here } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { //upgrade code here } It really works great in most cases. But from time to time I get a log similar to this: 06-10 23:49:59.621: I/DBHELPER1(26499): cxtcom.bananout.Bananout@407152c8 / instance: com.bananout.helpers.DatabaseHelper@40827560 06-10 23:49:59.631: I/DBHELPER2(26499): cxtcom.bananout.Bananout@407152c8 / instance: com.bananout.helpers.DatabaseHelper@40827560 06-10 23:49:59.631: I/DetailsLoader(26499): Get event details offline / db helper: com.bananout.helpers.DatabaseHelper@40827560 06-10 23:49:59.631: I/DBHELPER1(26499): cxtcom.bananout.Bananout@407152c8 / instance: com.bananout.helpers.DatabaseHelper@40827560 06-10 23:49:59.651: I/DBHELPER2(26499): cxtcom.bananout.Bananout@407152c8 / instance: com.bananout.helpers.DatabaseHelper@40827560 This line Log.i(TAG, "Get details offline / db: "+db); never gets called! No Exceptions, silence. Plus, the thread with the Loader is not running anymore. So nothing past this line SQLiteDatabase db=DatabaseHelper.getInstance(this.getContext()).getWritableDatabase(); gets executed. What can possibly go wrong on this line?

  • Why use buffers to read/write Streams

    - by James Hay
    Following reading various questions on reading and writing Streams, all the various answers define something like this as the correct way to do it: private void CopyStream(Stream input, Stream output) { byte[] buffer = new byte[16 * 1024]; int read; while ((read = input.Read(buffer, 0, buffer.Length)) > 0) { output.Write(buffer, 0, read); } } Two questions: Why read and write in these smaller chunks? What is the significance of the buffer size used?

  • What is the best way to do Bit Field manipulation in Python?

    - by ZebZiggle
    I'm reading some MPEG Transport Stream protocol over UDP and it has some funky bitfields in it (length 13 for example). I'm using the "struct" library to do the broad unpacking, but is there a simple way to say "Grab the next 13 bits" rather than have to hand-tweak the bit manipulation? I'd like something like the way C does bit fields (without having to revert to C). Suggestions?
