  • Is there a config option in PHP to prevent undefined constants from being interpreted as strings?

    - by mrbinky3000
    This is from the php manual: http://us.php.net/manual/en/language.constants.syntax.php If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. I really don't like this behavior. If I have failed to define a required constant, I would rather the script fail so that I am forced define it. Is there any way to force PHP to crash the script if it tries to use an undefined constant? For example. Both of these scripts do the same thing. <?php define('DEBUG',1); if (DEBUG) echo('Yo!'); ?> and <?php if(DEBUG) echo('Yo!'); ?> I would rather the second script DIE and declare that it tried to use an undefined constant DEBUG.

  • wx Menu disappears from frame when shown as a popup

    - by Adam Fraser
    I'm trying to create a wx.Menu that will be shared between a popup (called on right-click), and a sub menu accessible from the frame menubar. The following code demonstrates the problem. If you open the "MENUsubmenu" from the menubar the item "asdf" is visible. If you right click on the frame content area, "asdf" will be visible from there as well... however, returning to the menubar, you will find that "MENUsubmenu" is vacant. Why is this happening and how can I fix it? import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): ''' R-click callback ''' f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) frame_menu = wx.Menu() f.MenuBar.Append(frame_menu, 'MENU') frame_menu.AppendMenu(-1,'submenu', m) f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop() Interestingly, appending the menu to MenuBar works, but is not the behavior I want: import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) f.MenuBar.Append(m, 'MENU') f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop()

  • Casting to generic type in Java doesn't raise ClassCastException?

    - by Kip
    I have come across a strange behavior of Java that seems like a bug. Is it? Casting an Object to a generic type (say, K) does not throw a ClassCastException even if the object is not an instance of K. Here is an example: import java.util.*; public final class Test { private static<K,V> void addToMap(Map<K,V> map, Object ... vals) { for(int i = 0; i < vals.length; i += 2) map.put((K)vals[i], (V)vals[i+1]); //Never throws ClassCastException! } public static void main(String[] args) { Map<String,Integer> m = new HashMap<String,Integer>(); addToMap(m, "hello", "world"); //No exception System.out.println(m.get("hello")); //Prints "world", which is NOT an Integer!! } }

  • How can I embed a PDF in a Word Doc, and access that PDF with VBA?

    - by Austin R
    I have a word doc with some ActiveX buttons on it. When one of these buttons is pressed, a UserForm pops up with a corresponding PDF displayed, like so: This is exactly the behavior I want. However, the problem is that for this to work, the user of the word doc needs to have each of the PDFs saved on their machine as well. Here's the code for one of the buttons: Private Sub AC1Button_Click() DisplayForm.AcroPDF1.LoadFile ("C:\Users\arose\Desktop\Security Control Doc\Sub PDFs\AC1.pdf") DisplayForm.Show End Sub As you can see, the path is hardcoded in. I need to be able to distribute this word doc without needing to distribute a bunch of PDFs along with it, so is there any way to embed PDFs in a word document in such a way that they're accessible by VBA? I've discovered here that it's reasonably easy to embed a PDF in any office doc. And I've tried that: But I can't figure out how to access that PDF object in my VBA code, in order to display it on the UserForm. Any insight is appreciated, thanks!

  • Deserializing a type at the current stream position with protobuf-net

    - by Arne Claassen
    I'm serializing several objects into a single stream, but when i try to read them back, i can't seem to get anything but the last object: ProtoBuf.Serializer.Serialize(stream, postA1); ProtoBuf.Serializer.Serialize(stream, postB2); stream.Position = 0; var postA2 = ProtoBuf.Serializer.Deserialize<Post>(stream); var postB2 = ProtoBuf.Serializer.Deserialize<Post>(stream); The first deserialize moves the stream to the end and postA2 contains the value of postB2, while postB2 is just an uninitialized instance. Is this expected behavior, and if so, how do you deserialize an object from a random position in a stream?

  • Modify EXE to stop launching firefox

    - by Random Joe
    I'm using a wireless modem program from my ISP. This program automatically disconnect when it detects the line is idle. It does so in 2-5 minutes of idle time. Whenever I reconnect, It will automatically fire up my default browser to the ISP portal. I DID NOT pay them to shove their web portal in my face 50 times a day. The ISP provides no options for disabling this behavior. Can someone please show me how to hex edit the EXE program to stop it from annoying the hell out of me?

  • How can I avoid properties being reset at design-time in tightly bound user controls?

    - by David Anderson
    I have UserControl 'A' with a label, and this property: /// <summary> /// Gets or Sets the text of the control /// </summary> [ Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Category("Appearance") ] public override string Text { get { return uxLabel.Text; } set { uxLabel.Text = value; } } I then have UserControl 'B' which has UserControl 'A' on it, and I set the Text Property to "My Example Label" in the designer. Then, I have my MainForm, which has UserControl 'B' on it. Each time I do a build or run, the Text property of UserControl 'A' is reset to its default value. I suppose this is because since I am doing a rebuild, it rebuilds both UserControl 'A' and 'B', thus causing the problem. How can I go about a better approach to design pattern to avoid this type of behavior when working with tightly bound controls and forms in a application?

  • Hard link not works under MacOS in GUI mode

    - by AntonAL
    Hi, i faced a little strange behavior, while using hard links. From terminal, i create a text file 1.txt and a hard link "to this file" nano 1.txt mkdir dir ln 1.txt ./dir/ I check the resulting hard link and see, that it's contents is the same, as of "original" file. less ./dir/1.txt I change the initial file ... nano 1.txt ... and see, that changes was reflected in hard-link less ./dir/1.txt I change content of hard-link (more correct, of course - file, being referenced with hard-link) ... nano ./dir/1.txt ... and see, that changes are reflected in initial file less 1.txt Until now, all going well... Now, I close terminal and start playing with created files (1.txt and ./dir/1.txt) from Finder. When i change on this two files with TextEdit, changes are not reflected in another file. Just like the hard link was teared off... Whats going on here ?

  • What's the reason for leaving an extra blank line at the end of a code file?

    - by Lord Torgamus
    Eclipse and MyEclipse create new Java files with an extra blank line after the last closing brace by default. I think CodeWarrior did the same thing a few years back, and that some people leave such blank lines in their code either by intention or laziness. So, this seems to be at least a moderately widespread behavior. As a former human language editor -- copy editing newspapers, mostly -- I find that those lines look like sloppiness or accidents, and I can't think of a reason to leave them in source files. I know they don't affect compilation in C-style languages, including Java. Are there benefits to having those lines, and if so, what are they?

  • How to stop .Net HttpWebRequest.GetResponse() raising an exception

    - by James
    Surely, surely, surely there is a way to configure the .Net HttpWebRequest object so that it does not raise an exception when HttpWebRequest.GetResponse() is called and any 300 or 400 status codes are returned? Jon Skeet does not think so, so I almost dare not even ask, but I find it hard to believe there is no way around this. 300 and 400 response codes are valid responses in certain circumstances. Why would we be always forced to incur the overhead of an exception? Perhaps there is some obscure configuration setting that evaded Jon Skeet? Perhaps there is a completely different type of request object that can be used that does not have this behavior? (and yes, I know you can just catch the exception and get the response from that, but I would like to find a way not to have to). Thanks for any help

  • Multiple complete HTTP requests stuck in TCP CLOSE_WAIT state

    - by Sean Owen
    I have a Java and Tomcat-based server application which initiates many outbound HTTP requests to other web sites. We use Jakarta's HTTP Core/Client libraries, very latest versions. The server locks up at some point since all its worker threads are stuck trying to close completed HTTP connections. Using 'lsof' reveals a bunch of sockets stuck in TCP CLOSE_WAIT state. This doesn't happen for all, or even most connections. In fact, I saw it before and resolved it by making sure to set the Connection: Close response header. So that makes me think it may be bad behavior of remote servers. It may have come up again since I moved the app to a totally new service provider -- different OS, network situation. But, I am still at a loss as to what I could do, if anything, to work around this. Some poking around on the internet didn't turn up anything I'm not already doing. Just thought I'd ask if anyone has seen and solved this?

  • Why is SVN better than VSS? [closed]

    - by tsilb
    I've heard soooo many people complain about VSS, and noooo people complaining about SVN. We use SVN on my work project. It's slow, regularly freezes up my IDE, and has wonky behavior like looking for a database server every time I right-click the Solution node in my Solution Explorer. When I used VSS, everything worked beautifully, except for access restrictions which I of course blame on the people who control access. VSS is built by Microsoft and thus has great integration with Visual Studio. SVN is written by pretty much anybody with some free time (right?) and thus kinda works most of the time... And I honestly get the impression they had a dozen different directions in the design instead of one. So why do I keep hearing that SVN is better than VSS?

  • Rails redirect_to jQTouch site does not work as expected

    - by tilthouse
    I have a Rails app with a jQTouch mobile site that is displayed if the user goes to m.blah.com. First, I detect the browser, then to a redirect_to m.blah.com if it's an iphone, etc. All well and good. When I use desktop Safari, this all works exactly right. However, when I use an actual iPhone or the Apple iPhone Simulator, it does not. The mobile site appears to load without the browser actually doing the redirect. The URL in the browser is still www. I am wondering if this behavior is due to Mobile Safari, or if it is somehow jQTouch trying to load the page with AJAX, not a reload (which is odd as jQTouch hasn't been loaded at all before the redirect). Any ideas?

  • Why does TabStop stop working??

    - by Jerry
    I have a project that uses a series of auto-generated user control instances. The user-control itself exists, but I populate a panel with a series of these user controls, one for each item in my collection. Each user control displays a ton of information, but only ONE text field is editable. All of the other fields have TabStop set to false, and are marked as ReadOnly. The tab order of each user control is set at the time it is created so that the tab-key goes from one field to the next (or ... it's supposed to). When I have TWO fields on my user control whose TabStop is set to true, everything works great. But if I only have ONE field whose TabStop is true, the tab key stops working, and I have to physically CLICK on the next user control for it to gain focus. What's up? Has anyone else seen this behavior? Am I doing something stupid as usual?

  • Should I distinguish OpenIDs based on protocol prefix or not? http vs https

    - by Joannes Vermorel
    I have implemented a straightforward OpenID support for my ASP.NET app with DotNetOpenAuth. Yet I recently realized that the implementation was treating http://johndoe.example.com/ as a distinct user compared to https://johndoe.example.com. This lead to quite a few confused users. I am unsure what to do at this point. Is this a bug or a feature? Indeed, I can consider this behavior as a feature: if the user specifies the HTTPS, the user might not want the system to accept HTTP auth in the first place. On the other hand: if the user specifies HTTPS out of sheer cluelessness (the casual web visitor is clueless concerning the purpose of the "S" part), then rejecting it's authentication attempt is confusing. What is considered as the best practice?

  • python, wrapping class returning the average of the wrapped members

    - by João Portela
    The title isn't very clear but I'll try to explain. Having this class: class Wrapped(object): def method_a(self): # do some operations return n def method_b(self): # also do some operations return n I wan't to have a class that performs the same way as this one: class Wrapper(object): def __init__(self): self.ws = [Wrapped(1),Wrapped(2),Wrapped(3)] def method_a(self): results=[Wrapped.method_a(w) for w in self.ws] sum_ = sum(results,0.0) average = sum_/len(self.ws) return average def method_b(self): results=[Wrapped.method_b(w) for w in self.ws] sum_ = sum(results,0.0) average = sum_/len(self.ws) return average obviously this is not the actual problem at hand (it is not only two methods), and this code is also incomplete (only included the minimum to explain the problem). So, what i am looking for is a way to obtain this behavior. Meaning, whichever method is called in the wrapper class, call that method for all the Wrapped class objects and return the average of their results. Can it be done? how? Thanks in advance. ps-didn't know which tags to include...

  • Unable to catch exception from Activator.CreateInstance.

    - by Patrik Hägne
    OK, I admit it this code will just look weird to you, and that's because it is weird. This is just code to reproduce the behavior, not code I want to use. class Program { static void Main(string[] args) { try { Activator.CreateInstance(typeof(Func<int>), new object[] { new object(), IntPtr.Zero }); } catch { Console.WriteLine("This won't print!"); } Console.Write("Actually this will not print either!"); Console.ReadLine(); } } No matter what exception type I try to catch (the actual exception thrown is an ArgumentException as far as I can tell) the code inside the catch block will not execute. Actually execution will just stop at the Activator.CreateInstance-line.

  • Stopping Windows Mobile 6.5 tab reordering

    - by PaulH
    I have a C++ Visual Studio 2008 Windows Mobile 6.5 application that uses a tab control. I've noticed that depending on how careful you are with the stylus, when using the tab control you can accidentally re-order the tabs. It's difficult to do deliberately, but it's very easy to do when you're not trying. I assume this is a new "feature" of Windows Mobile 6.5 as it doesn't happen in Windows Mobile 6.1 with the same code. Is there a window style or something I can set that will lock the tab order such that people don't accidentally re-arrange them? Also, is there an MSDN page that describes this behavior and how it is supposed to work? I've looked, but have come up empty. Thanks, PaulH

  • What's the best way to detect web applications attacks ?

    - by paulgreg
    What is the best way to survey and detect bad users behavior or attacks like deny of services or exploits on my web app ? I know server's statistics (like Awstats) are very useful for that kind of purpose, specially to see 3XX, 4XX and 5XX errors (here's an Awstats example page) which are often bots or bad intentioned users that try well-known bad or malformed URLs. Is there others (and betters) ways to analyze and detect that kind of attack tentative ? Note : I'm speaking about URL based attacks, not attacks on server's component (like database or TCP/IP).

Registry.GetValue(...); But, I'm facing a curious behavior : Every time, the returned value is the correct one, but sometimes, it is followed by an unexpected "?" When I check the Registry, (regedit), the "?" doesn't exist. I really don't understand from where this question mark come from. Could someone help me please ? Info : - C# - 3.5 framework - windows 7 64 bits (and i want my application to work on both 32 and 64 bits systems) Thank you in advance, Wilhelm

  • Does C99 guarantee that arrays are contiguous ?

    - by kriss
    Following an hot comment thread in another question, I came to debate of what is and what is not defined in C99 standard about C arrays. Basically when I define a 2D array like int a[5][5], does the standard C99 garantee or not that it will be a contiguous block of ints, can I cast it to (int *)a and be sure I will have a valid 1D array of 25 ints. As I understand the standard the above property is implicit in the sizeof definition and in pointer arithmetic, but others seems to disagree and says casting to (int*) the above structure give an undefined behavior (even if they agree that all existing implementations actually allocate contiguous values). More specifically, if we think an implementation that would instrument arrays to check array boundaries for all dimensions and return some kind of error when accessing 1D array, or does not give correct access to elements above 1st row. Could such implementation be standard compilant ? And in this case what parts of the C99 standard are relevant.

  • Objective C - Constants with behaviour

    - by Akshay
    Hi, I'm new to Objective C. I am trying to define Constants which have behavior associated with them. So far I have done - @interface Direction : NSObject { NSString *displayName; } -(id)initWithDisplayName:(NSString *)aName; -(id)left; // returns West when North -(id)right; // return East when North @end @implementation Direction -(id)initWithDisplayName:(NSString *)aName { if(self = [super init]) { displayName = aName; } return self; } -(id)left {}; -(id)right {}; @end Direction* North = [Direction initWithDisplayName:@"North"]; // error - initializer element is not constant. This approach results in the indicated error. Is there a better way of doing this in Objective C.

  • Implementing a configurable factory

    - by Decko
    I'm having difficulties finding out how to implement a 'configurable' behavior in a factory class in PHP. I've got at class, which takes another class as an argument in its constructor. The argument class could take a number of arguments in its constructor. An instance of my main class could look something like this $instance = new MyClass(new OtherClass(20, true)); $instance2 = new MyClass(new DifferentClass('test')); This is rather clumsy and has a number of problems and therefore I would like to move this into a factory class. The problem is that this factory somehow needs to know how to instantiate the argument class, as this class can have any number of arguments in the constructor. Preferably I would like to be able to do something like this $instance = Factory::build('OtherClass'); $instance2 = Factory::build('DifferentClass'); And let the factory retrieve the arguments from a configuration array or similar. Is there a proper solution to this problem?

  • How can I render a custom view in a UIScrollView at varying zoom levels without distorting the view?

    - by eczarny
    The scenario: I have a custom view (a subclass of UIView) that draws a game board. To enable the ability to zoom into, and pan around, the board I added my view as a subview of UIScrollView. This kind of works, but the game board is being rendered incorrectly. Everything is kind of fuzzy, and nothing looks right. The question: How can I force my view to be redrawn correctly ay varying scales? I'm providing my view with the current scale and sending it a setNeedsDisplay message after the scroll view is done zooming in/out, but the game board is still being rendered incorrectly. My view should be redrawing the game board depending on the zoom level, but this isn't happening. Does the scroll view perform a generic transformation on subviews? Is there a way to disable this behavior?
