• Loading .sql files from within PHP

  - by Josh Smeaton

  I'm creating an installation script for an application that I'm developing and need to create databases dynamically from within PHP. I've got it to create the database but now I need to load in several .sql files. I had planned to open the file and mysql_query it a line at a time - until I looked at the schema files and realised they aren't just one query per line. So, please.. how do I load an sql file from within PHP? (as phpMyAdmin does with it's import command).

• Access or import an Outlook 2003 .pst file without Outlook

  - by Nobler

  I have a 450 meg .pst file (MS Outlook 2003 backup file) saved from a PC before it crashed. I would like to break it up into its components i.e. Save attachments to folders on my PC Paste text-emails into a word processor, etc. But I don't want to buy MS Office Professional 2003 or later solely for importing the .pst into MS Outlook 2003+. Outlook Express cannot import .pst files, only Outlook “proper” can. Is there some free email client out there, e.g. Thunderbird, that can import .pst files? Or is there some other way to access the 450meg file?

• Fastest reliable way to open the terminal?

  - by meder

  I actually had my SUPER_L ( left windows key ) binded to gnome-terminal, but for whatever reason ever since upgrading to 9.04 Ubuntu from 8.10 Intrepid it seemed to break the key binding. It was very handy because I could throw open the terminal with one key ( sorry but alt-f2 and typing gnome-terminal isn't practical for me ). Or perhaps it reset all the keybindings? I remember using xev and some gui type interface that was akin to Win32 registry editor. Anyway, I'm curious as to what you guys use to open the terminal.

• Powershell equivilent of python's if __name__ == '__main__':

  - by Mark Mascolino

  I am really fond of python's capability to do things like this: if __name__ == '__main__': #setup testing code here #or setup a call a function with parameters and human format the output #etc... This is nice because I can treat a Python script file as something that can be called from the command line but it remains available for me to import its functions and classes into a separate python script file easily without triggering the default "run from the command line behavior". Does Powershell have a similar facility that I could exploit? And if it doesn't how should I be organizing my library of function files so that i can easily execute some of them while I am developing them?

• Nice way to show Powerpoints and Video

  - by kamikatze

  I'm looking for a sleek way to display Powerpoint presentations and video footage in sequence. Embedding video in .ppsx is not something i want to do, reasons are plenty (video footage being VC-1 1080p would be the first). Is there a media player (needs to run on win32) capable of playing both formats? My hackish way of doing this would be a .cmd with powerpnt.exe bobloblaw.ppsx mplayer.exe -fs video.wmv pwoerpnt.exe whitepowerbill.ppsx and so on Of course, this has a lots an lots of drawbacks, including begin really hard to break out of the chain :) Thanks a lot.

• I have my best computer ideas while sitting in church. You? [closed]

  - by Rolnik

  At the risk of posing a subjective question... Where/when are you when you come up with your best ideas? How do you enter that 'zen' state? Yes... necessarily these have to be computer ideas and not new ideas how to make waffles (unless it involves a CPU). Some kinds of ideas include: New software project; better way to organize data; What would look slick on the internet; How to break into the Coka-Cola mainframe and steal the Coke formula (just kidding) How about it. How/when do you get a load of inspiration/insight?

• unsetting application role in classic ASP

  - by user303526

  Hi, I'm trying to unset an application role but have been failing miserably. I was able to get the cookie value after setting (sp_setapprole) the application role. But I haven't been able to use that cookie (type varbinary / byte array) in my query to unset using sp_unsetapprole. If it was any other stored procedure it wouldn't have been a problem. I was able to use Command object and create a parameter which takes data type input of adVarBinary (204) and execute the command line.. but to the Server the query goes as below. exec sp_executesql N'sp_unsetapprole @P1 ',N'@P1 varbinary(36)',0x01000000CD11697F8F0ED3627BC1DAD25FB9CEB3A2EC5B289C658235E510CD9F29230000 Since sp_setapprole and sp_unsetapprole have to be run ad hoc, the sql server is failing to run this line. And I'm finding it hard to append varbinary cookie value to a simple query such as 'sp_unsetapprole ' & varKookie so it runs "directly" on to the server. Any kind of suggestions are welcome. Thanks, Nandagopal

I do see the ... but then my TextView only has a max line of 2, instead of 6. Can you please how can I make the text view of maximum line of 6 and add '...' when it get truncated? Thank you.

• SVN Merge returns nothing...

  - by Mike

  Here is the scenario: Windows Vista environment. SVN version 1.6.11. I'm on my branch directory. I want to update my branch with a particular change from my trunk. Using command line (using SlikSVN) I enter the following and it returns nothing (returns a blank line and no merge occurs): svn merge -r 11846:11891 http://trunk//AppConstants.java When I do the equivalent using Tortoise SVN, it says "Completed" but nothing gets merged either. When I do a svn diff I clearly see the differences I want to merge in from the trunk to my branch. The diff command I am using is svn diff -r 11846:11891 http://trunk//AppConstants.java. Can anyone figure why no merge occurs? Thanks!!!

• Given two lines on a plane, how to find integer points closest to their interseciton?

  - by Lukasz Lew

  I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach.

• PowerShell script halts execution when Windows XP PC is locked

  - by jshin47

  I have the following script that does a continuous ping and reports failures. It works fine, except the loop apparently "suspends" when the computer is locked. I have confirmed this by starting the script, immediately locking the PC, waiting 10 minutes, and seeing how many pings have occurred. It is nowhere near the expected number. What could be the culprit? Write-Host "Entering monitoring loop..." -Background DarkRed $ping = new-object System.Net.NetworkInformation.Ping $count_up = 0 $count_dn = 0 $count_dd = 0 while ($true) { $result = $ping.send("10.1.1.1") if ($result.Status -eq "Success") { $count_up++ $count_dd = 0 } else { $count_dn++ $count_dd++ $this_date = Get-Date Write-Host "VPN ping failed at time " $this_date -Background Magenta if ($count_dd -gt 3) { Write-Host "***VPN is Down***" `a send_mail_notification("VPN is Down", "") } } if ($Host.UI.RawUI.KeyAvailable -and ("q" -eq $Host.UI.RawUI.ReadKey("IncludeKeyUp,NoEcho").Character)) { Write-Host "Exiting monitoring loop..." -Background DarkRed break; } Start-Sleep -m 250 } $total = $count_up + $count_dn $uptime = 100 * $count_up / $total Write-Host $count_up " out of " $total " pings for a " $uptime "% uptime."

• How to unit test synchronized code

  - by gillJ

  Hi, I am new to Java and junit. I have the following peice of code that I want to test. Would appreciate if you could send your ideas about what's the best way to go about testing it. Basically, the following code is about electing a leader form a Cluster. The leader holds a lock on the shared cache and services of the leader get resumed and disposed if it somehow looses the lock on the cache. How can i make sure that a leader/thread still holds the lock on the cache and that another thread cannot get its services resumed while the first is in execution? public interface ContinuousService { public void resume(); public void pause(); } public abstract class ClusterServiceManager { private volatile boolean leader = false; private volatile boolean electable = true; private List<ContinuousService> services; protected synchronized void onElected() { if (!leader) { for (ContinuousService service : services) { service.resume(); } leader = true; } } protected synchronized void onDeposed() { if (leader) { for (ContinuousService service : services) { service.pause(); } leader = false; } } public void setServices(List<ContinuousService> services) { this.services = services; } @ManagedAttribute public boolean isElectable() { return electable; } @ManagedAttribute public boolean isLeader() { return leader; } public class TangosolLeaderElector extends ClusterServiceManager implements Runnable { private static final Logger log = LoggerFactory.getLogger(TangosolLeaderElector.class); private String election; private long electionWaitTime= 5000L; private NamedCache cache; public void start() { log.info("Starting LeaderElector ({})",election); Thread t = new Thread(this, "LeaderElector ("+election+")"); t.setDaemon(true); t.start(); } public void run() { // Give the connection a chance to start itself up try { Thread.sleep(1000); } catch (InterruptedException e) {} boolean wasElectable = !isElectable(); while (true) { if (isElectable()) { if (!wasElectable) { log.info("Leadership requested on election: {}",election); wasElectable = isElectable(); } boolean elected = false; try { // Try and get the lock on the LeaderElectorCache for the current election if (!cache.lock(election, electionWaitTime)) { // We didn't get the lock. cycle round again. // This code to ensure we check the electable flag every now & then continue; } elected = true; log.info("Leadership taken on election: {}",election); onElected(); // Wait here until the services fail in some way. while (true) { try { Thread.sleep(electionWaitTime); } catch (InterruptedException e) {} if (!cache.lock(election, 0)) { log.warn("Cache lock no longer held for election: {}", election); break; } else if (!isElectable()) { log.warn("Node is no longer electable for election: {}", election); break; } // We're fine - loop round and go back to sleep. } } catch (Exception e) { if (log.isErrorEnabled()) { log.error("Leadership election " + election + " failed (try bfmq logs for details)", e); } } finally { if (elected) { cache.unlock(election); log.info("Leadership resigned on election: {}",election); onDeposed(); } // On deposition, do not try and get re-elected for at least the standard wait time. try { Thread.sleep(electionWaitTime); } catch (InterruptedException e) {} } } else { // Not electable - wait a bit and check again. if (wasElectable) { log.info("Leadership NOT requested on election ({}) - node not electable",election); wasElectable = isElectable(); } try { Thread.sleep(electionWaitTime); } catch (InterruptedException e) {} } } } public void setElection(String election) { this.election = election; } @ManagedAttribute public String getElection() { return election; } public void setNamedCache(NamedCache nc) { this.cache = nc; }

• Why the different coarse threaded screws?

  - by Luke

  I'm seeing more and more of these screws (pictured below), which are almost triangular. I find I can only put them into Power Supplies and PCI(e) cards in cases, but they will break/strip away if I put them into a hard drive or a standoff for a motherboard Notice the triangular shape on it? On the Root Access chat, I started asking, but no concrete answer yet. I don't assume it's a production flaw, as I've seen hundreds and replaced them with the "proper" round screws. It is coarse-threaded, not fine-threaded (i.e. for a DVD drive or floppy drive). What are they for, and why do we need them instead of the regular round ones?

• ASP.Net Checkbox Doesn't Allow Setting Visible to True

  - by Shawn Steward

  I'm working on an old web application in Visual Studio .Net 2003 (yeeich) and I'm having an issue with a Checkbox that will not set the Visibility to True. It's declared as such: Protected WithEvents chkTraining As System.Web.UI.WebControls.CheckBox and <asp:CheckBox id="chkTraining" runat="server" Visible="False"></asp:CheckBox> When I am debugging through the line that has: chkTraining.Visible = True it goes past it fine, but as I check this value on the very next line, chkTraining.Visible = False. What could possibly be going on here? There's no events firing off or anything else going on... this really is throwing me for a loop. Thanks for your help.

• Same Activity called twice... Issue with Multiple AsyncTasks?

  - by stormin986

  I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. Could this be from both onPostExecute()s executing simultaneously and both checking the flags each other set at the exact same time? This seems extremely unlikely since two processes would have to be running line-by-line in parallel... *EDIT* A lot removed from this question since I was way off in what I thought was wrong. Nonetheless I found the answer here quite useful, so I have edited the question to reflect the useful parts.

• How to extract a Sub-Matrix from a Matrix ?

  - by ZaZu

  Hello, I have a matrix in a txt file and I want to load the matrix based on my input of number of rows and columns For example, I have a 5 by 5 matrix in the file. I want to extract a 3 by 3 matrix, how can I do that ? I created a nested loop using : FILE *sample sample=fopen("randomfile.txt","r"); for(i=0;i<rows;i++){ for(j=0;j<cols;j++){ fscanf(sample,"%f",&matrix[i][j]); } fscanf(sample,"\n",&matrix[i][j]); } fclose(sample); Sadly the code does not work .. If I have this matrix : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 3.00 4.00 23.00 5.00 2.00 352.00 6.00 And inputting 3 for rows and 3 for columns, I get : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 Which is obviously wrong , its reading line by line rather than skipping the unmentioned column ... What am I doing wrong ? Thanks !

• Python and sqlite3 - importing and exporting databases

  - by JPC

  I'm trying to write a script to import a database file. I wrote the script to export the file like so: import sqlite3 con = sqlite3.connect('../sqlite.db') with open('../dump.sql', 'w') as f: for line in con.iterdump(): f.write('%s\n' % line) Now I want to be able to import that database. I tried: import sqlite3 con = sqlite3.connect('../sqlite.db') f = open('../dump.sql','r') str = f.read() con.execute(str) but I'm not allowed to execute more than one statement. Is there a way to get it to run a .sql script directly?

• DataGridView: how to focus the whole row instead of a single cell?

  - by Tomas Sedovic

  I'd like to use the DataGridView control as a list with columns. Sort of like ListView in Details mode but I want to keep the DataGridView flexibility. ListView (with Details view and FullRowSelect enabled) highlights the whole line and shows the focus mark around the whole line: DataGridView (with SelectionMode = FullRowSelect) displays focus mark only around a single cell: So, does anyone know of some (ideally) easy way to make the DataGridView row selection look like the ListView one? I'm not looking for a changed behaviour of the control - I only want it to look the same. Ideally, without messing up with the methods that do the actual painting.
