• Windows media player control with .NET

  - by brovar

  What I want to do is to read media files (pics and videos) from a directory and display them one by one using the WMP control (AxWMPLib.AxWindowsMediaPlayer). In its older version it was enough to check the file's duration to distinguish images from videos, the new one randomly shows movies' duration properly or as zero. Does anyone know any other way of finding out what file is being proceeded withouth checking its extension (as a file can have an extension of .abc or so)? I'll be very grateful for any help. (Sorry for my lousy English.)

• Recursion Interview Questions [closed]

  - by halivingston

  Given a string, "ABC", print all permutations Given a dollar bill, fill out possible ways it can summed up using .25, .10, .5, etc. Given a phone number (123-456), print out all it's word counter parters like (ADG-XYZ) A B C D E F G H I J K L M N O P In the above 2D matrix, print all possible words (just literally all words, and sure we could check if it's exists in a dictionary). The base case is I think here is that reaching the same i, j positions. Any others you can think of?

• Catching errors in ANTLR and finding parent

  - by Andreas

  I have found out that I can catch errors during parsing by overwriting displayRecognitionError, but how do I find the parent "node" of this error? ex. if I have the grammar: prog: stat expr; stat: STRING; expr: INTEGER; And give it the input "abc def". Then I will get an error at "def" which should be an integer. At this point I then want to get the parent which is "expr" (since it fails inside the INTEGER part) and it's parent "prog". Kind of like printing stack trace in java. I tried to look at the node from RecognitionException parsed to displayRecognitionError, but it is null, and using CommonErrorNode the parent is null. Should I maybe take a completely different approach?

• How do you get the logical xor of two variables in Python?

  - by Zach Hirsch

  How do you get the logical xor of two variables in Python? For example, I have two variables that I expect to be strings. I want to test that only one of them contains a True value (is not None or the empty string): str1 = raw_input("Enter string one:") str2 = raw_input("Enter string two:") if logical_xor(str1, str2): print "ok" else: print "bad" The ^ operator seems to be bitwise, and not defined on all objects: >>> 1 ^ 1 0 >>> 2 ^ 1 3 >>> "abc" ^ "" Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for ^: 'str' and 'str'

  Hello i have a cpp code wich i'm having trouble reading. a class B is defined now, i understand the first two lines, but the rest isn't clear enough. is the line "B const * pa2 = pa1" defines a const variable of type class B? if so, what does the next line do? B a2(2); B *pa1 = new B(a2); B const * pa2 = pa1; B const * const pa3 = pa2; also, i'm having trouble figuring out the difference between these two: char const *cst = “abc”; const int ci = 15; thank you

• So, I guess I can't use "&&" in the Python if conditional. Any help?

  - by Sergio Tapia

  Here's my code: # F. front_back # Consider dividing a string into two halves. # If the length is even, the front and back halves are the same length. # If the length is odd, we'll say that the extra char goes in the front half. # e.g. 'abcde', the front half is 'abc', the back half 'de'. # Given 2 strings, a and b, return a string of the form # a-front + b-front + a-back + b-back def front_back(a, b): # +++your code here+++ if len(a) % 2 == 0 && len(b) % 2 == 0: return a[:(len(a)/2)] + b[:(len(b)/2)] + a[(len(a)/2):] + b[(len(b)/2):] else: #todo! Not yet done. :P return I'm getting an error in the IF conditional. What am I doing wrong?

• Eclipse call hierarchy skips calls in undefined #ifdef regions

  - by stupakov

  Hi all, The "call hierarchy" and "declaration" features in Eclipse CDT omit results that exist in undefined (greyed out) #ifdef regions. Example: void blah(void) { #ifndef ABC foo(); #else //line is greyed out bar(); //line is greyed out #endif //line is greyed out } The call hierarchy for foo() will list blah() as a caller; the call hierarchy for bar() will not list blah(). I'm not expecting it to do full resolution of which #define blocks will get compiled, I simply would like it to return all calls/declarations of the function I'm searching for, regardless of the #define blocks that surround it. Other IDEs such as SlickEdit are able to do this. Does anyone know of a way to get Eclipse to adopt this behavior? Thanks.

• Prevent Carousel scroll within scrollable Container (Sencha 2)?

  - by TragedyStruck

  I've got a Container with a header, content (Carousel) and a footer. The Container itself is therefor scrollable (vertical) to be able to scroll down to the footer. The Carousel can be swiped horizontally to change active item. I want to lock it to do only two thing: If starting to move vertically, only scroll Container If starting to move horizontally, only scroll Carousel If you now grab the Carousel you are able to scroll both ways at the same time. Example code: Ext.define('MyApp.view.MyContainer', { extend: 'Ext.Container', config: { scrollable: true, items: [ { xtype: 'container', items: [ { xtype: 'label', html: 'abc' } ] }, { xtype: 'carousel', height: 200, scrollable: false, items: [ { xtype: 'label', html: 'x' }, { xtype: 'label', html: 'y<br/>y<br/>y<br/>y<br/>y<br/>y<br/>y<br/>y' } ] }, { xtype: 'container', items: [ { xtype: 'label', html: 'def' } ] } ] } }); Using Sencha Touch 2.

• How does Windows' 'Open with' work?

  - by Frederick

  I was under the impression that when you double click a file (or choose 'Open With' from the right click menu), Windows simply calls the application with the filename as the parameter. Something like this: C: App.exe file.abc However, I just double clicked an .xls file and then checked the PEB of the Excel instance that sprang up. To my surprise the commandline did not contain the filename as a parameter. So that set me wondering. What exactly is mechanism Windows uses to have a file opened by a relevant application? Is there a special API that each application that supports such facility must expose?

• How to facet multiple columns in Google Refine

  I have a data set with 30 columns and multiple rows (some cells have no data). I would like to be able to facet the columns in groups. 1 2 3 4..... Row1 A B C D Row2 E A D F Row3 Q A B H Given the above data I would like the facet to retun the number of instances in a group of columns. For the first three columns I need the facet to return: A - 3 B - 2 C - 1 D - 1 E - 1 Q - 1 I have tried to combine columns when I loaded the data but the individual data was grouped as well. This is not the desired outcome. For example: ABC - 1 EAD - 1 QAB - 1 Thanks in advance.

• Storing XML in SQL 2005 XMLNS issue

  - by Mike Mengell

  I'm trying to store XML in SQL 2005. I have a very simple table with an Id and a XML column. When the XML contains the attribute xmlns my searching doesn't work. This is my XML; insert into XMLTest (ItemXML) values ( '<MessageType> <ItemId id="ABC" xmlns="ss" /> <Subject>sub</Subject> </MessageType> ') And this is my Query; select itemid, ItemXML.query('(/MessageType/ItemId)') from XMLTest order by ItemId desc If I change the attribute xmlns to anything else my query works. I don't think I know enough about XML to understand what SQL is doing with the namespace. But it must be processing it and storing it differently maybe? Anyone had this issue?
