• Access 2007 DAO VBA Error 3381 causes objects in calling methods to "break".

  - by MT

  ---AFTER FURTHER INVESTIGATION--- "tblABC" in the below example must be a linked table (to another Access database). If "tblABC" is in the same database as the code then the problem does not occur. Hi, We have recently upgraded to Office 2007. We have a method in which we have an open recordset (DAO). We then call another sub (UpdatingSub below) that executes SQL. This method has its own error handler. If error 3381 is encountered then the recordset in the calling method becomes "unset" and we get error 3420 'Object invalid or no longer set'. Other errors in UpdatingSub do not cause the same problem. This code works fine in Access 2003. Private Sub Whatonearth() Dim rs As dao.Recordset set rs = CurrentDb.OpenRecordset("tblLinkedABC") Debug.Print rs.RecordCount UpdatingSub "ALTER TABLE tblTest DROP Column ColumnNotThere" 'Error 3240 occurs on the below line even though err 3381 is trapped in the calling procedure 'This appears to be because error 3381 is encountered when calling UpdatingSub above Debug.Print rs.RecordCount End Sub Private Sub WhatonearthThatWorks() Dim rs As dao.Recordset set rs = CurrentDb.OpenRecordset("tblLinkedABC") Debug.Print rs.RecordCount 'Change the update to generate a different error UpdatingSub "NONSENSE SQL STATEMENT" 'Error is trapped in UpdatingSub. Next line works fine. Debug.Print rs.RecordCount End Sub Private Sub UpdatingSub(strSQL As String) On Error GoTo ErrHandler: CurrentDb.Execute strSQL ErrHandler: 'LogError' End Sub Any thoughts? We are running Office Access 2007 (12.0.6211.1000) SP1 MSO (12.0.6425.1000). Perhaps see if SP2 can be distributed? Sorry about formatting - not sure how to fix that.

• Python: Beginning problems

  - by Blogger

  ok so basically i very new to programming and have no idea how to go about these problems help if you will ^^ Numerologists claim to be able to determine a person’s character traits based on the “numeric value” of a name. The value of a name is determined by summing up the values of the letters of the name, where ‘a’ is 1, ‘b’ is 2, ‘c’ is 3 etc., up to ‘z’ being 26. For example, the name “Zelle” would have the value 26 + 5 + 12 + 12 + 5 = 60 (which happens to be a very suspicious number, by the way). Write a program that calculates the numeric value of a single name provided as input. Word count. A common utility on Unix/Linux systems is a small program called “wc”. This program counts the number of lines, words (strings of characters separated by blanks, tabs, or new lines), and characters in a file. Write your own version of this program. The program should accept a file name as input and then print three numbers showing the count of lines, words, and characters in the file.

• C++ class is not being included properly.

  - by ravloony

  Hello all, I have a problem which is either something I have completely failed to understand, or very strange. It's probably the first one, but I have spent the whole afternoon googling with no success, so here goes... I have a class called Schedule, which has as a member a vector of Room. However, when I compile using cmake, or even by hand, I get the following: In file included from schedule.cpp:1: schedule.h:13: error: ‘Room’ was not declared in this scope schedule.h:13: error: template argument 1 is invalid schedule.h:13: error: template argument 2 is invalid schedule.cpp: In constructor ‘Schedule::Schedule(int, int, int)’: schedule.cpp:12: error: ‘Room’ was not declared in this scope schedule.cpp:12: error: expected ‘;’ before ‘r’ schedule.cpp:13: error: request for member ‘push_back’ in ‘((Schedule*)this)->Schedule::_sched’, which is of non-class type ‘int’ schedule.cpp:13: error: ‘r’ was not declared in this scope Here are the relevant bits of code: #include <vector> #include "room.h" class Schedule { private: std::vector<Room> _sched; //line 13 int _ndays; int _nrooms; int _ntslots; public: Schedule(); ~Schedule(); Schedule(int nrooms, int ndays, int ntslots); }; Schedule::Schedule(int nrooms, int ndays, int ntslots):_ndays(ndays), _nrooms(nrooms),_ntslots(ntslots) { for (int i=0; i<nrooms;i++) { Room r(ndays,ntslots); _sched.push_back(r); } } In theory, g++ should compile a class before the one that includes it. There are no circular dependencies here, it's all straightforward stuff. I am completely stumped on this one, which is what leads me to believe that I must be missing something. :-D

• count how many days within a date range are within another date range

  - by joko13

  From October 1st to March 31 the fee is $1 (season 1). From April 1st to September 30 the fee is $2 (season 2). How can I calculate the total fee of a given date range (user input) depending on how many days of this date range fall into season 1 and season 2? The following gives me the number of days of the user´s date range, but I have no idea how to test against season 1 or season 2: $user_input_start_date = getdate( $a ); $user_input_end_date = getdate( $b ); $start_date_new = mktime( 12, 0, 0, $user_input_start_date['mon'], $user_input_start_date['mday'], $user_input_start_date['year'] ); $end_date_new = mktime( 12, 0, 0, $user_input_end_date['mon'], $user_input_end_date['mday'], $user_input_end_date['year'] ); return round( abs( $start_date_new - $end_date_new ) / 86400 ); Thanks for your help! EDIT: Given that a date range starts and ends in 2012 or starts in 2012 and ends in 2013 alone gives me 10 different possibilities of in which season a date range can start and where it can end. There must be a better solution than iterating if/else and comparing dates over and over again for the following conditions: Date range is completely within season 1 Date range starts in season 1 and ends in season 2 Date range starts in season 1, spans across season 2 and ends in the second part of season 1 ... and so forth with "Starts in season 2", etc

  i'm creating a windows phone app ,where i've put a button to pin the app to start screen , but when press and hold the app icon on application list screen i find that the pin to start option can be used ShellTile TileToFind = ShellTile.ActiveTiles.FirstOrDefault(x => x.NavigationUri.ToString().Contains("MainPage.xaml")); // Create the Tile if we didn't find that it already exists. if (TileToFind == null) { // Create the Tile object and set some initial properties for the Tile. // The Count value of 12 shows the number 12 on the front of the Tile. Valid values are 1-99. // A Count value of 0 indicates that the Count should not be displayed. StandardTileData NewTileData = new StandardTileData { BackgroundImage = new Uri("300.png", UriKind.Relative), Title = "apptitle", BackTitle = "title", BackContent = "testing ", BackBackgroundImage = null }; // Create the Tile and pin it to Start. This will cause a navigation to Start and a deactivation of our app. ShellTile.Create(new Uri("/MainPage.xaml", UriKind.Relative), NewTileData); } else { MessageBox.Show("Already Pinned"); } how can i disable the user from pinning the application again from application list screen

• querying huge database table takes too much of time in mysql

  - by Vijay

  Hi all, I am running sql queries on a mysql db table that has 110Mn+ unique records for whole day. Problem: Whenever I run any query with "where" clause it takes at least 30-40 mins.

• How can I reorder an mbox file chronologically?

  - by Joshxtothe4

  Hello, I have a single spool mbox file that was created with evolution, containing a selection of emails that I wish to print. My problem is that the emails are not placed into the mbox file chronologically. I would like to know the best way to place order the files from first to last using bash, perl or python. I would like to oder by received for files addressed to me, and sent for files sent by me. Would it perhaps be easier to use maildir files or such? The emails currently exist in the format: From [email protected] Fri Aug 12 09:34:09 2005 Message-ID: <[email protected]> Date: Fri, 12 Aug 2005 09:34:09 +0900 From: me <[email protected]> User-Agent: Mozilla Thunderbird 1.0.6 (Windows/20050716) X-Accept-Language: en-us, en MIME-Version: 1.0 To: someone <[email protected]> Subject: Re: (no subject) References: <[email protected]> In-Reply-To: <[email protected]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit Status: RO X-Status: X-Keywords: X-UID: 371 X-Evolution-Source: imap://[email protected]/ X-Evolution: 00000002-0010 Hey the actual content of the email someone wrote: > lines of quotedtext I am wondering if there is a way to use this information to easily reorganize the file, perhaps with perl or such.

• Python raw strings and trailing back slashes.

  - by dash-tom-bang

  I ran across something once upon a time and wondered if it was a Python "bug" or at least a misfeature. I'm curious if anyone knows of any justifications for this behavior. I thought of it just now reading "Code Like a Pythonista," which has been enjoyable so far. I'm only familiar with the 2.x line of Python. Raw strings are strings that are prefixed with an r. This is great because I can use backslashes in regular expressions and I don't need to double everything everywhere. It's also handy for writing throwaway scripts on Windows, so I can use backslashes there also. (I know I can also use forward slashes, but throwaway scripts often contain content cut&pasted from elsewhere in Windows.) So great! Unless, of course, you really want your string to end with a backslash. There's no way to do that in a 'raw' string. In [9]: r'\n' Out[9]: '\\n' In [10]: r'abc\n' Out[10]: 'abc\\n' In [11]: r'abc\' ------------------------------------------------ File "<ipython console>", line 1 r'abc\' ^ SyntaxError: EOL while scanning string literal In [12]: r'abc\\' Out[12]: 'abc\\\\' So one slash before the closing quote is an error, but two slashes gives you two slashes! Certainly I'm not the only one that is bothered by this? Thoughts on why 'raw' strings are 'raw, except for slash-quote'? I mean, if I wanted to embed a single quote in there I'd just use double quotes around the string, and vice versa. If I wanted both, I'd just triple quote. If I really wanted three quotes in a row in a raw string, well, I guess I'd have to deal, but is this considered "proper behavior"?

• Sampling Duplicates

  - by user3640982

  I have a dataset from which I need to sample. It is set up with an ID field and a year field. I want every record from the most current year and then I want the most current ID's but sampled from every 3rd year going back. The data is ordered by year. For example ID<-rep(1:3, 5) Year<-rep(c(1,2,3,4,5),each=3) df<-data.frame(ID,Year) ID Year 1 1 1 2 2 1 3 3 1 4 1 2 5 2 2 6 3 2 7 1 3 8 2 3 9 3 3 10 1 4 11 2 4 12 3 4 13 1 5 14 2 5 15 3 5 So from this example, I would want to return ID Year 1 1 1 2 2 1 3 3 1 4 1 4 5 2 4 6 3 4 I'm thinking that some combination of duplicated() and which() should get what I want, but the problem is duplicated() just tells if it has been repeated; it doesn't say which record is being repeated. which(duplicated(df$ID)) [1] 4 5 6 7 8 9 10 11 12 13 14 15 This a problem since not every ID exists in every year. Any help would be appreciated. Thanks, Eric

• Parsing data with Clojure, interval problem.

  - by Andrea Di Persio

  Hello! I'm writing a little parser in clojure for learning purpose. basically is a TSV file parser that need to be put in a database, but I added a complication. The complication itself is that in the same file there are more intervals. The file look like this: ###andreadipersio 2010-03-19 16:10:00### USER COMM PID PPID %CPU %MEM TIME root launchd 1 0 0.0 0.0 2:46.97 root DirectoryService 11 1 0.0 0.2 0:34.59 root notifyd 12 1 0.0 0.0 0:20.83 root diskarbitrationd 13 1 0.0 0.0 0:02.84` .... ###andreadipersio 2010-03-19 16:20:00### USER COMM PID PPID %CPU %MEM TIME root launchd 1 0 0.0 0.0 2:46.97 root DirectoryService 11 1 0.0 0.2 0:34.59 root notifyd 12 1 0.0 0.0 0:20.83 root diskarbitrationd 13 1 0.0 0.0 0:02.84 I ended up with this code: (defn is-header? "Return true if a line is header" [line] (> (count (re-find #"^\#{3}" line)) 0)) (defn extract-fields "Return regex matches" [line pattern] (rest (re-find pattern line))) (defn process-lines [lines] (map process-line lines)) (defn process-line [line] (if (is-header? line) (extract-fields line header-pattern)) (extract-fields line data-pattern)) My idea is that in 'process-line' interval need to be merged with data so I have something like this: ('andreadipersio', '2010-03-19', '16:10:00', 'root', 'launchd', 1, 0, 0.0, 0.0, '2:46.97') for every row till the next interval, but I can't figure how to make this happen. I tried with something like this: (def process-line [line] (if is-header? line) (def header-data (extract-fields line header-pattern))) (cons header-data (extract-fields line data-pattern))) But this doesn't work as excepted. Any hints? Thanks!

• How many custom tabs can I add to a Facebook page?

  - by Maxi Ferreira

  I'm building a web application to create custom tabs and add them to the user's Facebook fanpages. I know how the process of "installing" FB apps into FB pages so they show up as Page Tabs works, but the problem is the client wants to allow the user to create unlimited Page Tabs for a single FB Page. So I have basically two questions. 1 - Can I resue a single FB App to be included into the same page several times? If so, is there a way to know what is the "id" of that Page Tab? So, if I have my FB App to look for the Tab content in http://www.mywebapp.com/tab/, I know I get a signed_request with the App ID and the Page ID, but if that same App is installed several times into the same Page, I don't know what's the Tab the user have cliked on. I know it's a little big messy, and I don't think there's a way to do this. So my next question is probably more accurate. 2 - Is there a limit on how many Tabs can I add to a single Facebook page? This way, if there's a limit of, say, 12 Tabs, I can create 12 FB Tab Apps, store the ID's and then I know which Tab of which Page the user is currently viewing. Thanks in advice! Maxi

• Add less than integer variable to string search

  - by user1691832

  I'm scanning a text document for certain installed programs on a computer and looking for an easy way to include a greater or less than variable in the string I'm scanning for. Here is a very ugly and cumbersome example of what I'm using currently and while it works as a temporary fix, isn't practical or sustainable. If CheckBox2.Checked Then sReader.Close() If text.Contains("Adobe Flash Player 11 Plugin") And text.Contains("Adobe Flash Player 11 ActiveX") Then Else If text.Contains("Adobe Flash Player 12 Plugin") And text.Contains("Adobe Flash Player 12 ActiveX") Then Else If text.Contains("Adobe Flash Player 13 Plugin") And text.Contains("Adobe Flash Player 13 ActiveX") Then Else '(Goes ahead and does a silent install of the missing or outdated program) So far I've run into this problem with both Adobe Flash and Java RTE and am certain to run into it with future programs. Essentially I need to scan for "Adobe Flash Player (Any number less than 11) Plugin" , "Adobe Flash Player (Any number less than 11) ActiveX" , "Java (number less than 9) Update (any number)". I'm sure whatever solution is offered can likely be adapted to similar programs I'm likely to encounter later. Thanks ----- Edit ----- I've since tried the following code but it always returns the "Found" messagebox, even when no version of adobe flash is present in the file it is scanning. If CheckBox2.Checked Then sReader.Close() Dim options As RegexOptions = RegexOptions.None Dim regex As Regex = New Regex("Adobe Flash Player (?<version>\d+) (Plugin|ActiveX)", options) Dim input As String = "Adobe Flash Player 11 Plugin" ' Get match Dim match As Match = regex.Match(input) Dim version As String = match.Groups("version").Value If (match.Success) Then MessageBox.Show("Version 11 or higher found, skipping install") Else MessageBox.Show("Version 11 or higher not found, installing Version 11")

• Better way to summarize data about stop times?

  - by Vimvq1987

  This question is close to this: http://stackoverflow.com/questions/2947963/find-the-period-of-over-speed Here's my table: Longtitude Latitude Velocity Time 102 401 40 2010-06-01 10:22:34.000 103 403 50 2010-06-01 10:40:00.000 104 405 0 2010-06-01 11:00:03.000 104 405 0 2010-06-01 11:10:05.000 105 406 35 2010-06-01 11:15:30.000 106 403 60 2010-06-01 11:20:00.000 108 404 70 2010-06-01 11:30:05.000 109 405 0 2010-06-01 11:35:00.000 109 405 0 2010-06-01 11:40:00.000 105 407 40 2010-06-01 11:50:00.000 104 406 30 2010-06-01 12:00:00.000 101 409 50 2010-06-01 12:05:30.000 104 405 0 2010-06-01 11:05:30.000 I want to summarize times when vehicle had stopped (velocity = 0), include: it had stopped since "when" to "when" in how much minutes, how many times it stopped and how much time it stopped. I wrote this query to do it: select longtitude, latitude, MIN(time), MAX(time), DATEDIFF(minute, MIN(Time), MAX(time)) as Timespan from table_1 where velocity = 0 group by longtitude,latitude select DATEDIFF(minute, MIN(Time), MAX(time)) as minute into #temp3 from table_1 where velocity = 0 group by longtitude,latitude select COUNT(*) as [number]from #temp select SUM(minute) as [totaltime] from #temp3 drop table #temp This query return: longtitude latitude (No column name) (No column name) Timespan 104 405 2010-06-01 11:00:03.000 2010-06-01 11:10:05.000 10 109 405 2010-06-01 11:35:00.000 2010-06-01 11:40:00.000 5 number 2 totaltime 15 You can see, it works fine, but I really don't like the #temp table. Is there anyway to query this without use a temp table? Thank you.

• How does mercurial's bisect work when the range includes branching?

  - by Joshua Goldberg

  If the bisect range includes multiple branches, how does hg bisect's search work. Does it effectively bisect each sub-branch (I would think that would be inefficient)? For instance, borrowing, with gratitude, a diagram from an answer to this related question, what if the bisect got to changeset 7 on the "good" right-side branch first. @ 12:8ae1fff407c8:bad6 | o 11:27edd4ba0a78:bad5 | o 10:312ba3d6eb29:bad4 |\ | o 9:68ae20ea0c02:good33 | | | o 8:916e977fa594:good32 | | | o 7:b9d00094223f:good31 | | o | 6:a7cab1800465:bad3 | | o | 5:a84e45045a29:bad2 | | o | 4:d0a381a67072:bad1 | | o | 3:54349a6276cc:good4 |/ o 2:4588e394e325:good3 | o 1:de79725cb39a:good2 | o 0:2641cc78ce7a:good1 Will it then look only between 7 and 12, missing the real first-bad that we care about? (thus using "dumb" numerical order) or is it smart enough to use the full topography and to know that the first bad could be below 7 on the right-side branch, or could still be anywhere on the left-side branch. The purpose of my question is both (a) just to understand the algorithm better, and (b) to understand whether I can liberally extend my initial bisect range without thinking hard about what branch I go to. I've been in high-branching bisect situations where it kept asking me after every test to extend beyond the next merge, so that the whole procedure was essentially O(n). I'm wondering if I can just throw the first "good" marker way back past some nest of merges without thinking about it much, and whether that would save time and give correct results.

• How to make placeholder varablies in jquery validate 1.7?

  - by chobo2

  Hi I am using jquery 1.4.2 and jquery validate 1.7(http://bassistance.de/jquery-plugins/jquery-plugin-validation/) Say I have this example that I just grabbed off some random site(http://www.webreference.com/programming/javascript/jquery/form_validation/) 8 <script type="text/javascript"> 9 $(document).ready(function() { 10 $("#form1").validate({ 11 rules: { 12 name: "required",// simple rule, converted to {required:true} 13 email: {// compound rule 14 required: true, 15 email: true 16 }, 17 url: { 18 url: true 19 }, 20 comment: { 21 required: true 22 } 23 }, 24 messages: { 25 comment: "Please enter a comment." 26 } 27 }); 28 }); 29 </script> now is it possible to do something like this 10 $("#form1").validate({ var NameHolder = "name" 11 rules: { 12 NameHolder: "required",// simple rule, converted to {required:true} 13 email: {// compound rule 14 required: true, 15 email: true So basically I want to make sort of a global variable to hold theses rule names( what correspond to the names on that html control). My concern is the names of html controls can change and it kinda sucks that I will have to go around and change it in many places of my code to make it work again. So basically I am wondering is there away to make a global variable to store this name. So if I need to change the name I only have to change it in one spot in my javascript file sort of the way stopping magic numbers ?

• JQuery set img src depending on where you click

  - by Anna

  Hello ! I used javascript for loading a picture on my website depending on which "small" photos in ul you clicked... I had something like that : <script type="text/javascript"> function viewImage(src, legende) { document.getElementById("imageBig").src = "images/photos/"+src; document.getElementById("legend").innerHTML = legende; } </script> and in html simply : things like that : <li><a href="#centre" onclick="javascript:viewImage('flute.jpg','La Reine de la Nuit au Comedia')"><img src="images/photos/carre-09.jpg" alt="" /></a> <a href="#centre" onclick="javascript:viewImage('perichole.jpg','Manuelita - <em>La P&eacute;richole</em> &agrave; l&#8217;Op&eacute;ra Comique')"><img src="images/photos/carre-03.jpg" alt="" /></a></li> <li><a href="#centre" onclick="javascript:viewImage('12.png','R&eacute;cital &agrave; Carnac, septembre 2008')"><img src="images/photos/carre-12.jpg" alt="Marion Baglan Carnac R&eacute;" /></a> <a href="#centre" onclick="javascript:viewImage('01.jpg','')"><img src="images/photos/carre-01.jpg" alt="" /></a></li> so you see, I could, depending on which small photos in the unordered list you clicked, load some particular photos, by passing the src string in argument... but I decided to use Jquery to get some fade-in effect. But I can't find a way to pass an argument that would tell my JQuery function which photo to load depending on where I clicked... stuck here : $(document).ready(function(){ $('#ulPhotos').click(function() { var newSrc= $('#imageBig').attr("src", "images/photos/11.jpg"); }); }); I don't want the 11.jpg to be hardcoded, I need to pass it through argument when I click on a special li element in my ul element of id #ulPhotos... I hope I'm clear enough sorry !
