    - by Henry

  • How do VoIP services connect to landlines?

    - by henry
    How do VoIP services, such as Skype and Yahoo, connect to landlines? We have a server connected to a landline using asterisk, so I'm thinking this server will bridge our VoIP conversation and connect it to a landline. But if this is the case, wouldn't Skype need a lot of servers placed around the whole world just to connect to landlines?

  • paypal sadbox IPN

    - by Phil Jackson
    Morning all. I am trying to test a SIMPLE php script to deal with the IPN response from paypal sandbox. <?php // read the post from PayPal system and add 'cmd' $req = 'cmd=_notify-validate'; foreach ($post as $key => $value) { $value = urlencode(stripslashes($value)); $req .= "&$key=$value"; } // post back to PayPal system to validate $header = "POST /cgi-bin/webscr HTTP/1.0\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: " . strlen($req) . "\r\n\r\n"; $fp = fsockopen ('ssl://www.sandbox.paypal.com/', 443, $errno, $errstr, 30); if ( !$fp ) { // HTTP ERROR $fp = fopen('thinbg.txt', 'a'); fwrite($fp, "false !fp - " . implode(" ", $post) ); fclose($fp); } else { fputs ($fp, $header . $req); while (!feof($fp)) { $res = fgets ($fp, 1024); if (strcmp ($res, "VERIFIED") == 0) { // PAYMENT VALIDATED & VERIFIED! $fp2 = fopen('thinbg.txt', 'a'); fwrite($fp2, "true - " . implode(" ", $post) ); fclose($fp2); } else if (strcmp ($res, "INVALID") == 0) { // PAYMENT INVALID & INVESTIGATE MANUALY! $fp2 = fopen('thinbg.txt', 'a'); fwrite($fp2, "false - " . implode(" ", $post) ); fclose($fp2); } } fclose ($fp); } ?> When I click on "send IPN" in the test ac"IPN successfully sent". when I look at the file that I created to check the vars it begins with "false !fp" yet still displays all the vars. Can anyone see whats happening and how I go about fixing. Regards, Phil

  • looping through JSON array

    - by Phil Jackson
    Hi all. I have recently posted another question which straight away users pointed me in the right direction. $.ajax({ type: 'POST', url: './', data: 'token=' + token + '&re=8', cache: false, timeout: 5000, success: function(html){ auth(html); var JSON_array = eval(html); alert(JSON_array[0].username); } }); this returns the data correctly but I want to perform a kind of 'foreach'. the array contains data about multiple incoming and outgoing Instant Messages. So if a user is talking to more than one person at a time i need to loop through. the array's structure is as follows. Array ( [0] => Array ( [username] => Emmalene [contents] => <ul><li class="name">ACTwebDesigns</li><li class="speech">helllllllo</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">sds</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">Sponge</li><li class="speech">dick</li></ul> <ul><li class="name">ACTwebDesigns</li><li class="speech">arghh</li></ul> ) ) any help very much appreciated.

  • how to split a very large database on sql server

    - by ken jackson
    I have a 90 GB SQL Server database that I want to make more manageable. It stores stock data from 50+ different stocks from 2009 and 2010, and each stock is a separate table. Some tables have hundreds of millions of rows, and other have just a few million. What I want to do is somehow split the database, so that I don't have a single database file that is 90 GB. What I want is to be able to somehow magically split all the tables so that I can backup the 2009 data once and not have to keep on including it in the backup every time I backup the entire database, however, I would like the 2009 data to be included whenever I do a query. Is partitioning the database the way to go? Will it do the above for me, or will I need some other solution? I research partitioning, but I wasn't sure if that would solve all my problems. I wasn't able to find anything that would tell me whether or not it would migrate prexisting data, or whether it only worked for newly inserted data. Any help or pointers would be much appreciated. Thanks in advance, Ken

  • Can JNI handle any dll files (Windows)?

    - by henry
    I am new to JNI. And have a few questions : Can JNI handle every type dll exists in windows? I wanted to link a library but it gives me error. Is it possible JNI and the dll are not compatible? Excerpt from VB .NET (It works) Private Declare Function ConnectReader Lib "rfidhid.dll" () As Integer Private Declare Function DisconnectReader Lib "rfidhid.dll" () As Integer Private Declare Function SetAntenna Lib "rfidhid.dll" (ByVal mode As Integer) As Integer Full Code From Java public class MainForm { /** * @param args */ public native int ConnectReader(); public static void main(String[] args) { // TODO Auto-generated method stub MainForm mf = new MainForm(); System.out.println(mf.ConnectReader()); } static { System.loadLibrary("rfidhid"); } } Error code shown Exception in thread "main" java.lang.UnsatisfiedLinkError: MainForm.ConnectReader()I at MainForm.ConnectReader(Native Method) at MainForm.main(MainForm.java:13) Can anyone point to me where I might do wrong

  • How to retrieve view of MultiIndex DataFrame

    - by Henry S. Harrison
    This question was inspired by this question. I had the same problem, updating a MultiIndex DataFrame by selection. The drop_level=False solution in Pandas 0.13 will allow me to achieve the same result, but I am still wondering why I cannot get a view from the MultiIndex DataFrame. In other words, why does this not work?: >>> sat = d.xs('sat', level='day', copy=False) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Python27\lib\site-packages\pandas\core\frame.py", line 2248, in xs raise ValueError('Cannot retrieve view (copy=False)') ValueError: Cannot retrieve view (copy=False) Of course it could be only because it is not implemented, but is there a reason? Is it somehow ambiguous or impossible to implement? Returning a view is more intuitive to me than returning a copy then later updating the original. I looked through the source and it seems this situation is checked explicitly to raise an error. Alternatively, is it possible to get the same sort of view from any of the other indexing methods? I've experimented but have not been successful. [edit] Some potential implementations are discussed here. I guess with the last question above I'm wondering what the current best solution is to index into arbitrary multiindex slices and cross-sections.

  • FileSystemWatcher keeping parent directory

    - by Henry Jackson
    I am using FileSystemWatcher to monitor a folder, and it seems to be preventing the folder's parent from being deleted. For example, I have the file structure: C:\Root\FolderToWatch\... with the FileSystemWatcher targeting FolderToWatch. While my program is running, if I go to Windows Explorer and try to delete Root, I get an error "Cannot delete Root: access is denied". However, if I delete FolderToWatch FIRST, I can then delete Root without incident. (Needless to say, if the FileSystemWatcher is not enabled, I have no problem deleting either folder.) What gives? Why does the FileSystemWatcher hang onto it's target's parent like that? How (if possible) can I stop this behavior? I would like the user to be able to freely move or delete directories in Windows Explorer.

  • mysql query - syntax error - cannot find out why

    - by Phil Jackson
    Hi all, im taring my hair out over this one. A query is throwing an error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM, SUBJECT, DATE, READ, MAIL ) VALUES ( 'EJackson', 'dfdf', '1270974101', 'fa' at line 1 I printed out the query to see what could be the problem: INSERT INTO db.tablename ( FROM, SUBJECT, DATE, READ, MAIL ) VALUES ( 'EJackson', 'dfdf', '1270974299', 'false', 'dfdsfdsfd' ) and finaly the structure consists of: CREATE TABLE db.tablename ( `ID` int(12) NOT NULL auto_increment, `FROM` varchar(255) NOT NULL, `SUBJECT` varchar(255) NOT NULL, `DATE` varchar(255) NOT NULL, `READ` varchar(255) NOT NULL, `MAIL` varchar(255) NOT NULL, PRIMARY KEY (`ID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; I cant find anything wrong. Any Help would be much appreciated. ( db.tablename is a replacement for the actual tablename )

  • IEnumerable<T> representing the "rest" of an IEnumerable<T> sequence

    - by Henry Jackson
    If I am walking through an IEnumerable<T>, is there any way to get a new IEnumerable<T> representing the remaining items after the current one. For example, I would like to write an extension method IEnumerator<T>.Remaining(): IEnumerable<int> sequence = ... IEnumerator<int> enumerator = sequence.GetEnumerator(); if (enumerator.MoveNext() && enumerator.MoveNext()) { IEnumerable<int> rest = enumerator.Remaining(); // 'rest' would contain elements in 'sequence' start at the 3rd element } I'm thinking of the collection of a sort of singly-linked list, so there should be a way to represent any remaining elements, right? I don't see any way to do this exposed on either IEnumerable<T> or IEnumerator<T>, so maybe it's incompatible with the notion of a potentially unbounded, nondeterministic sequence of elements.

  • When is ¦ not equal to ¦?

    - by Trey Jackson
    Background. I'm working with netlists, and in general, people specify different hierarchies by using /. However, it's not illegal to actually use a / as a part of an instance name. For example, X1/X2/X3/X4 might refer to instance X4 inside another instance named X1/X2/X3. Or it might refer an instance named X3/X4 inside an instance named X2 inside an instance named X1. Got it? There's really no "regular" character that cannot be used as a part of an instance name, so you resort to a non-printable one, or ... perhaps one outside of the standard 0..127 ASCII chars. I thought I'd try (decimal) 166, because for me it shows up as the pipe: ¦. So... I've got some C++ code which constructs the path name using ¦ as the hierarchical separator, so the path above looks like X1¦X2/X3¦X4. Now the GUI is written in Tcl/Tk, and to properly translate this into human readable terms I need to do something like the following: set path [getPathFromC++] ;# returns X1¦X2/X3¦X4 set humanreadable [join [split $path ¦] /] Basically, replace the ¦ with / (I could also accomplish this with [string map]). Now, the problem is, the ¦ in the string I get from C++ doesn't match the ¦ I can create in Tcl. i.e. This fails: set path [getPathFromC++] ;# returns X1¦X2/X3¦X4 string match $path [format X1%cX2/X3%cX4 166 166] Visually, the two strings look identical, but string match fails. I even tried using scan to see if I'd mixed up the bit values. But set path [getPathFromC++] ;# returns X1¦X2/X3¦X4 set path2 [format X1%cX2/X3%cX4 166 166] for {set i 0} {$i < [string length $path]} {incr i} { set p [string range $path $i $i] set p2 [string range $path2 $i $i] scan %c $p c scan %c $p2 c2 puts [list $p $c :::: $p2 $c2 equal? [string equal $c $c2]] } Produces output which looks like everything should match, except the [string equal] fails for the ¦ characters with a print line: ¦ 166 :::: ¦ 166 equal? 0 For what it's worth, the character in C++ is defined as: const char SEPARATOR = 166; Any ideas why a character outside the regular ASCII range would fail like this? When I changed the separator to (decimal) 28 (^\), things worked fine. I just don't want to get bit by a similar problem on a different platform. (I'm currently using Redhat Linux).

  • How can I run Ruby specs and/or tests in MacVim without locking up MacVim?

    - by Henry
    About 6 months ago I switched from TextMate to MacVim for all of my development work, which primarily consists of coding in Ruby, Ruby on Rails and JavaScript. With TextMate, whenever I needed to run a spec or a test, I could just command+R on the test or spec file and another window would open and the results would be displayed with the 'pretty' format applied. If the spec or test was a lengthy one, I could just continue working with the codebase since the test/spec was running in a separate process/window. After the test ran, I could click through the results directly to the corresponding line in the spec file. Tim Pope's excellent rails.vim plugin comes very close to emulating this behavior within the MacVim environment. Running :Rake when the current buffer is a test or spec runs the file then splits the buffer to display the results. You can navigate through the results and key through to the corresponding spot in the file. The problem with the rails.vim approach is that it locks up the MacVim window while the test runs. This can be an issue with big apps that might have a lot of setup/teardown built into the tests. Also, the visual red/green html results that TextMate displays (via --format pretty, I'm assuming) is a bit easier to scan than the split window. This guy came close about 18 mos ago: http://cassiomarques.wordpress.com/2009/01/09/running-rspec-files-from-vim-showing-the-results-in-firefox/ The script he has worked with a bit of hacking, but the tests still ran within MacVim and locked up the current window. Any ideas on how to fully replicate the TextMate behavior described above in MacVim? Thanks!

  • VB.net Need Text Box to Only Accept Numbers

    - by Rico Jackson
    I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems. Thanks again to anyone who can help. If TxtBox.Text > 10 Then MessageBox.Show("Please Enter a Number from 1 to 10") TxtBox.Focus() ElseIf TxtBox.Text < 10 Then MessageBox.Show("Thank You, your rating was " & TxtBox.Text) Total = Total + 1 ElseIf IsNumeric(TxtBox.Text) Then MessageBox.Show("Thank you, your rating was " & ValueTxtBox.Text) End If ValueTxtBox.Clear() ValueTxtBox.Focus()
