  • Adding an NSTextField as a subview

    - by Kenny
    I'm trying to add an NSTextField as a subview of a custom view class I have (which subclasses NSView), and then make the text field the first responder. This works fine... the text field shows up and I can start typing in it. However, any mouse events in the text field seem to fall through to its superview. For example, I can't see the mouse cursor when I hover over the text field, and when I click anywhere in the text field, it attempts to resign firstResponder status instead of letting me select text within the text field. I'm not overridding hitTest or anything weird like that, and I only have one window, which is definitely the key window. Any ideas? Thanks in advance! :-)

  • Loading external SWF with masked content - need width/height

    - by AZSL
    I am loading an external swf using the SWFLoader component. The swf that is being loaded is masked so that only a portion is being shown. However, when it's loaded the actual size of the swf (loader.content.width/loader.content.height) is the complete swf including the masked area. Therefore, the loaded swf does not display properly in the itemrenderer Is there a way to to grab the size of the just the masked area as opposed to getting the size of the entire swf's contents? One item to note that is complicating the issue, is that these are swf files that have already been created and there are many of them. In some instances, the size of the stage matches up with the size of the masked area. In other instances, the stage is larger (or possibly smaller) than the masked area movieclip as well as possibly the actual size of the movieclip (w/o the mask). I am currently loading the external swf in using a Loader. Once loaded, I make a copy (screen shot) of the swf by creating a bmp of the loader.content.This is done as I don't want to have any animations being shown on screen at this moment. I am setting the size of the bmp using using loader.content.width & loader.content.height. I then set the SWFLoader.source to the bitmap.

  • How to get a number closest to the average in c++?

    - by Alex Zielinski
    What I'm trying to achieve is to take the average of the numbers stored in the array and find the number which is closest to it. My code compiles, but has an error just after starting. I think it's something to do with the memory handling (I don't feel confident with pointers, etc. yet) Could some nice guy take a look at my code and tell me what's wrong with it? (don't be hard on me, I'm a beginner) #include <iostream> #include <cmath> using namespace std; double* aver(double* arr, size_t size, double& average); int main() { double arr[] = {1,2,3,4,5,7}; size_t size = sizeof(arr)/sizeof(arr[0]); double average = 0; double* p = aver(arr,size,average); cout << *p << " " << average << endl; } double* aver(double* arr, size_t size, double& average){ int i,j,sum; double* m = 0; int tmp[7]; for(i=0;i<size;i++) sum += arr[i]; average = sum/size; for(j=0;j<size;j++){ tmp[j] = arr[j] - average; if(abs(tmp[j])>*m) *m = tmp[j]; } return m; }

  • When writing to the Windows Event Log, is it possible to create a custom link text for URLs?

    - by thomasnguyencom
    I'm just using the vanilla EventLog.WriteEntry method: EventLog.WriteEntry(EVENT_SOURCE, message, EventLogEntryType.Error, id); Here's how the message shows up in the Event Log, with the links in the parenthesis working just fine, but it's ugly: Example 1: Please contact us via email (mailto:[email protected]) or online (http://example.com). Here's how the message shows up in the Event Log, with the HTML "markup", doesn't even handle it: Example 2: Please contact us via <a href="mailto:[email protected]">email</a> or <a href="http://example.com">online</a>. This is how I would like the message to show up, but with "email" and "online" as the link texts: Example 3: Please contact us via email or online. I've tried the <a href>...</a> HTML tags with no success.

  • Java: how to tell if a line in a text file was supposed to be blank?

    - by defn
    I'm working on a project in which I have to read in a Grammar file (breaking it up into my data structure), with the goal of being able to generate a random "DearJohnLetter". My problem is that when reading in the .txt file, I don't know how find out whether the file was supposed to be a completely blank line or not, which is detrimental to the program. Here is an example of part of the file, How do i tell if the next line was supposed to be a blank line? (btw I'm just using a buffered reader) Thanks! <start> I have to break up with you because <reason> . But let's still <disclaimer> . <reason> <dubious-excuse> <dubious-excuse> , and also because <reason> <dubious-excuse> my <person> doesn't like you I'm in love with <another> I haven't told you this before but <harsh> I didn't have the heart to tell you this when we were going out, but <harsh> you never <romantic-with-me> with me any more you don't <romantic> any more my <someone> said you were bad news

  • Programmaticaly grabbing text from a web page that is dynamically generated.

    - by bstullkid
    There is a website I am trying to pull information from in perl, however the section of the page I need is being generated using javascript so all you see in the source is <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it! If anyone is interested, the page is http://downloadcenter.trendmicro.com/index.php?clk=left_nav&clkval=pattern_file&regs=NABU and the info I am trying to get is the row about the ConsumerOPR

  • FIFO dequeueing in python?

    - by Aaron Ramsey
    hello again everybody— I'm looking to make a functional (not necessarily optimally efficient, as I'm very new to programming) FIFO queue, and am having trouble with my dequeueing. My code looks like this: class QueueNode: def __init__(self, data): self.data = data self.next = None def __str__(self): return str(self.data) class Queue: def__init__(self): self.front = None self.rear = None self.size = 0 def enqueue(self, item) newnode = QueueNode(item) newnode.next = None if self.size == 0: self.front = self.rear = newnode else: self.rear = newnode self.rear.next = newnode.next self.size = self.size+1 def dequeue(self) dequeued = self.front.data del self.front self.size = self.size-1 if self.size == 0: self.rear = None print self.front #for testing if I do this, and dequeue an item, I get the error "AttributeError: Queue instance has no attribute 'front'." I guess my function doesn't properly assign the new front of the queue? I'm not sure how to fix it though. I don't really want to start from scratch, so if there's a tweak to my code that would work, I'd prefer that—I'm not trying to minimize runtime so much as just get a feel for classes and things of that nature. Thanks in advance for any help, you guys are the best.

  • How to preserve whitespace indentation of text enclosed in HTML <pre> tags excluding the current indentation level of the <pre> tag in the document?

    - by Michael Barton
    I'm trying to display my code on a website but I'm having problems preserving the whitespace indentation correctly. For instance given the following snippet: <html> <body> Here is my code: <pre> def some_funtion return 'Hello, World!' end </pre> <body> </html> This is displayed in the browser as: Here is my code: def some_funtion return 'Hello, World!' end When I would like it displayed as: Here is my code: def some_funtion return 'Hello, World!' end The difference is that that current indentation level of the HTML pre tag is being added to the indentation of the code. I'm using nanoc as a static website generator and I'm using google prettify to also add syntax highlighting. Can anyone offer any suggestions?

Mostly I want to remove few 'fixed' lines which are always present in email body. Do I need to run some sort of PHP process to do it? Is it possible to do it on email server itself? EDIT I have got cpanel access.

  • Is using a FSM a good design for general text parsing?

    - by eSKay
    I am reading a file that is filled with hex numbers. I have to identify a particular pattern, say "aaad" (without quotes) from it. Every time I see the pattern, I generate some data to some other file. This would be a very common case in designing programs - parsing and looking for a particular pattern. I have designed it as a Finite State Machine and structured structured it in C using switch-case to change states. This was the first implementation that occured to me. DESIGN: Are there some better designs possible? IMPLEMENTATION: Do you see some problems with using a switch case as I mentioned?

  • VB.NET - ASP.NET - MS-Access - SQL Statement

    - by Brian
    I have a button which when pressed, sets the user's rights in the db. (If Administrator UserTypeID is set to '2' and if Customer it is set to '1'). However when I run the below code, everything remains the same. I think it's from the SQL statement but I;m not sure. Can anyone help please?

  • Why is this if statement failing?

    - by Rawling
    I'm working on an existing class that is two steps derived from System.Windows.Forms.Combo box. The class overrides the Text property thus: public override string Text { get { return this.AccessibilityObject.Value; } set { if (base.Text != value) { base.Text = value; } } } The reason given for that "get" is this MS bug: http://support.microsoft.com/kb/814346 However, I'm more interested in the fact that the "if" doesn't work. There are times where "base.Text != value" is true and yet pressing F10 steps straight to the closing } of the "set" and the Text property is not changed. I've seen this both by just checking values in the debugger, and putting a conditional breakpoint on that only breaks when the "if" statement's predicate is true. How on earth can "if" go wrong? The class between this and ComboBox doesn't touch the Text property. The bug above shouldn't really be affecting anything - it says it's fixed in VS2005. Is the debugger showing different values than the program itself sees?

  • UI suggestions on how to display suggested tags for a given text to a user?

    - by Danny
    I am writing a web-app that uses a tagging system to organize the user's submitted reports. Part of it uses ajax to get suggestions for tags to present to the user based on the content of their report. I am looking for suggestions on how to present this information for the user. I'm not quite certain what a friendly way to do this would be. Edit: Well, most of the responses here seem to be focused on the user typing in keywords. The idea I'm trying to define here is more towards presenting the user a set of suggested keywords that they may accept or decline without having to type a tag in manually. (That option is of course still available to them) --------------------------- # say they can checkoff or select tags they like. | o[tag2] x[foo] o[moo] | | x[tag1] o[bar] | ---------------------------
