• asp.net InsertCommand to return latest insert ID

  - by Stijn Van Loo

  Dear all, I'm unable to retrieve the latest inserted id from my SQL Server 2000 db using a typed dataset in asp.NET I have created a tableadapter and I ticked the "Refresh datatable" and "Generate Insert, Update and Delete statements". This auto-generates the Fill and GetData methods, and the Insert, Update, Select and Delete statements. I have tried every possible solution in this thread http://forums.asp.net/t/990365.aspx but I'm still unsuccesfull, it always returns 1(=number of affected rows). I do not want to create a seperate insert method as the auto-generated insertCommand perfectly suits my needs. As suggested in the thread above, I have tried to update the InsertCommand SQL syntax to add SELECT SCOPY_IDENTITY() or something similar, I have tried to add a parameter of type ReturnValue, but all I get is the number of affected rows. Does anyone has a different take on this? Thanks in advance! Stijn

• Should a Parent with Children have a DefaultChild, or should a Child have a Default property?

  - by Stijn

  Which of the following two models makes more sense? I'm leaning towards the first one because there can only be one default child. The examples are in C# but I think it can apply to other languages too. Here DefaultChild holds one of the items in Children. class Parent { int ID { get; set; } Child DefaultChild { get; set; } IEnumerable<Child> Children { get; set; } } class Child { int ID { get; set; } } Here one of the items in Children has Default set to true while the others have it set to false. class Parent { int ID { get; set; } IEnumerable<Child> Children { get; set; } } class Child { int ID { get; set; } bool Default { get; set; } } A concrete situation: a User in our system has one or more Customers attached. When logging in, if said User has a default Customer, they are immediately working under this Customer. If they don't, they have to select a Customer to work under. While logged in, they can switch between Customers.

• Keep only essential packages

  - by Stijn

  In an attempt to learn more about Ubuntu and its packages, I want to remove all non-essential packages, so I can install what I need, when I need them and know what they do. I'm using the commands dpkg --clear-selections and apt-get dselect-upgrade for this. I also slightly modify the selection by setting apt libstdc++6 (due to apt) install-info (due to grep) to install again (somehow dpkg thinks they are not essential, but apt-get complains). Is this ok, or is this bad? If it's ok, what do I do with the large list of packages with "deinstall" status in dpkg? An additional note, I'm doing this on a VPS template so I have no control over the initially installed packages.

• My co-worker has not been doing such a good job for the past decade. What do I do? [closed]

  - by stijn

  Possible Duplicate: How do I approach a coworker about his or her code quality? I started working with him almost a decade ago and back then I had never really programmed before, being a young hardware engineer. Right now however I have made quite some progress in all areas being part of software design and i am much, much more skilled than my co-worker who is 15 years older and has been programming more than twice as long. He is super nice and definitely smart enough, but lately his lack of skill and performance are starting to drag me down because we're more and more working on the same codebase. And soon we are going to do a quite ambitious start from scratch creating a whole new hard/software system. I feel it is time to address all issues now, but i do not know how to start. Here are some of the things that I would like to see him improve on: no consistent usage of style, spaces nor tabs (eg if(something ) a =b ) adds newlines around pieces of code to make it easier to read, then commits those with messages like 'no changes made' overall commit messages are useless and so are most of the comments, if there are any (eg 'remove solves for bug Rik' if Rik reported a bug). There is no function/class documentation. lots of spelling errors, in both English and native language, which sometimes are mixed 6/7/8 level deep deep nesting is no exception, a lot of functions start with one level already like if(ptr!=Null){ even when ptr is the result of allocation via new in the constructor numerous source files have over 10k lines of those lines, a major part is simply a result of copy-pasting functionality instead of using a function. This includes copying comments so we end up with 50 occurrences of var=NULL; //TODO TEST this!!!!!!! another part is hundreds of lines of dead code knows what versioning does, yet comments out old code and places new code underneath it when making changes coding skills are below par, especially for the type of rather high precision applications we do. Yet somehow, after a lot of trying and testing, stuff starts to work. But then breaks again some time later because every change casues a waterfall effect. violates every single item in the C++ FAQ lite, practices every bad practice I can think of still doesn't know how to properly use the debugger, but spends hours inspecting messy logfiles in notepad on a tiny laptop screen. Does not make any adjustments to the settings of the software he uses. Never uses keyboard shortcuts. does not seem to progress or learn new things at all. Work rather slow, mostly due to the lack of planning and incorrect usage of tools. How does one deal with this? For starters, how do I make him aware of all these problems? Should I tell the staff about it? And the next step, how to get him to learn new things and adopt another way of working?

• Of which bad practice is require calling functions in order a sign?

  - by stijn

  Sometimes I find myself writing comments on class methods like this: class A : public Base { public: /** * Sets variable; * should be called before ImplementsInterfaceMtehod(), * else has no effect. */ void SetSomeVariable( var_type value ); virtual void ImplementsInterfaceMethod(); } The callers of Base::ImplementsInterfaceMethod obviously do not know about the variable, and should not. But the users of A should set the variable if they want it to take effect. It is not required to set the variable (else it could be a parameter for the constructor), so I cannot throw exceptions in ImplementsInterfaceMethod if it is not set. Is this a sign of some typical bad practice? Is there a better way than writing a comment as shown to deal with this?

• Are unit tests really used as documentation?

  - by stijn

  I cannot count the number of times I read statements in the vein of 'unit tests are a very important source of documentation of the code under test'. I do not deny they are true. But personally I haven't found myself using them as documentation, ever. For the typical frameworks I use, the method declarations document their behaviour and that's all I need. And I assume the unit tests backup everything stated in that documentation, plus likely some more internal stuff, so on one side it duplicates the ducumentation while on the other it might add some more that is irrelevant. So the question is: when are unit tests used as documentation? When the comments do not cover everything? By developpers extending the source? And what do they expose that can be useful and relevant that the documentation itself cannot expose?

• Criteria for selecting timeout value?

  - by stijn

  Situation: a piece of software reads frames of data from a file in a seperate thread and puts it on a queue, emptied by another thread. That second thread periodically checks on the queue and fails rather gracefully, by showing an error message stating the read timed out, if no data is available within a certain amount of time. Initially this timeout was set to 200mSec. There was no real reasoning behind that constant though, but it worked fine. We measured on a couple of machines and for large data frames, larger than what would be used by customers, a read took like 20mSec whith no other load on the machine. However one customer now gets timeout errors now and then (on the second try all is fine, probably the file is in cache or the virus scanner leaves it alone). The programmers are like 'well, yeah, but that customer's machine is full of cruft, virus scanners, tons of unneeded background processes etc'. Of course the customer is like 'hey this should just work, shouldn't it'? While the programers have a point, since the software is heavy enough to validate the need for a dedicated machine, that does not make the customer happy. Increasing the timeout to 2 seconds, for example, solves the problem. But I'd like to make a proper decision now instead of just randomly pick some magic constant that is probably ok in 99% of cases. What criteria should be used for that? We could just pick a large number, but that feels wrong. (and then we end up with a program that has the horrible bahaviour of hanging when trying to read from a disconnected drive for instance, whereas we'd rather make it show an error right away). Or we could make the timeout value a user setting, but then we need to ducument it clearly and even then not all customers are tech savy enough to really understand what it does. Or we could try and wait until another customer reports timeouts and increase the value again. And again. Until we find something ok for 99.99% of the cases.. Any good practice for this type of situation?

• Is it bad practice to use the same name for arguments and members?

  - by stijn

  Sometimes I write constructor code like class X { public: X( const int numberOfThingsToDo ) : numberOfThingsToDo( numberOfThingsToDo ) { } private: int numberOfThingsToDo; }; or in C# class X { public X( int numberOfThingsToDo ) { this.numberOfThingsToDo = numberOfThingsToDo; } private int numberOfThingsToDo; } I think the main reason is that when I come up with a suitable member name, I see no reason to use a different one for the argument initializing it, and since I'm also no fan of using underscores the easiest is just to pick the same name. After all it's suitable. Is this considered bad practice however? Any drawbacks (apart from shooting yourself in the foot when forgetting the this in C#)?

• Is imposing the same code format for all developers a good idea?

  - by Stijn Geukens

  We are considering to impose a single standard code format in our project (auto format with save actions in Eclipse). The reason is that currently there is a big difference in the code formats used by several (10) developers which makes it harder for one developer to work on the code of another developer. The same Java file sometimes uses 3 different formats. So I believe the advantage is clear (readability = productivity) but would it be a good idea to impose this? And if not, why? UPDATE We all use Eclipse and everyone is aware of the plan. There already is a code format used by most but it is not enforced since some prefer to stick to their own code format. Because of the above reasons some would prefer to enforce it.

• Don&rsquo;t apply for your first job somewhere; apply for an experience at Oracle.

  - by cristian.condurache(at)oracle.com

  Hi! My name is Stijn and I currently work as a Business Development Consultant for Oracle in Dublin since November 2010. I’m originally from Belgium and I graduated last year from the Vlerick Leuven Gent Management School. In many ways you could say I’m living the life I asked for: an international career with global organization. I’m unbelievably grateful however, because opportunities like this don’t come by the dozen. Actually, going through university and business school my dreams of an international career were clouded quite quickly. Following all the ‘right’ steps wasn’t enough. The lack of offers for, and trust in, new starters to take on a challenge like this was a reality check for me and many of my friends. It takes a company that recognizes the opportunity of recruiting talented individuals by offering them something they actually want: a first job based abroad! My job is focused on generating demand for Oracle products over the phone. In only a few months, the amazing things I’ve experienced, the people I’ve talked to, the learning experiences I’ve had in and outside of work are too many to list. From having CEO’s on the phone, to having meetings with 15 different nationalities, to getting settled from scratch in a new country… it’s something that builds you as a person. But don’t be fooled though, it’s on you - where it starts. Although Oracle gives you the best training and resources to do your job and Ireland is a playground for everything else, it’s you that is responsible. You are in control and much is expected. What you get in return however, is beyond incredible.

• DIY a simple .inf on an existing .sys?

  - by Stijn Sanders

  In continuation of attempting to get an old Digi ST-1032 working on a new server, we've downgraded a server to Windows 2000 in an attempt to use the NT4 drivers. And it works, the old software setup works, finds the device on the SCSI bus, and connects the 32 ports to COM3..COM34 or any other set using the port remapper tool. The minor issue that remains is that Plug-and-Play still detects this device over SCSI and tries to wizard you into selecting a driver for it. Which doesn't exists (Digi Intl support confirms this device is so old, a 2000 or XP driver was never made). The exact name displayed is "DigiIntl ST-1032 SCSI Net Device" (Oddly enough, two devices get detected with this name, on two neighbouring LUN's, could one be the built-in terminator?) Is there a way to concoct a simple .inf that would (re-)register the existing sts.sys that appears to get registered by the (old) installer of the driver software?

• Disassemble Asus A2500H

  - by Stijn Sanders

  I have an aged Asus A2500H notebook, with a broken screen and damage to the outside. Since it has a TV-out connection, and is working good otherwise, I have it hooked up to my television as a kind of media-center to play video over LAN. I want to remove the screen as cleanly as possible, but am having trouble opening up the laptop. I've been able to remove the (broken) hinges the screen pivots on. I've also removed any other screws I could spot, but still the casing doesn't come off and seems to be attached by yet more screws I can't access (yet). I've been searching the web for disassemble instructions, I've found some for a number of other brands and models, but not for the Asus A2500H.

• How to reboot a WindowsCE5 device?

  - by Stijn Sanders

  Is there a way to force a device running Windows CE 5.0 to reboot? I remember Ctrl+Alt+Del from the old days on PC's, but I don't know if there's a keyboard-combination I could use on this Datalogic BlackJet, and I can't seem to find a reset pin-hole. I tried taking the battery out, and waiting a few hours, but that totally reset the device from ROM, undoing all setup I'd done.

• Laptop wakes from sleep, once, due to audio controller (Windows 7)

  The laptop is a recent Dell XPS 15z and the problem is as follows (reproducible about 90% of tries): put laptop to sleep using either Start-Sleep or closing the lid laptop goes to sleep after about 5 seconds, but instantly wakes again showing a black screen (touching the keyboard or moving the mouse shows the login screen one normally gets after wake) login again, put laptop to sleep latop stays in sleep mode output of powercfg -lastwake after the first instant wake shows the audio controller is responsible. Why would that be, why only the first try, and how to fix this?

• Wii game bought in US, will it work on a PAL console in Europe?

  - by Stijn Sanders

  I can't seem to find a European online outlet that offers this Wii game I'm looking for. If I would buy it from a web-shop in the US, could I end up with a game that doesn't work well with my console? I'm worried because all games I have for the Wii so far have a prominent mention of "PAL" on the cover. I didn't notice "NTSC" on the photo's of the cover online, but I'm worried none the less. (And thought I'd ask it here first...) Also, does anyone happen to know if Belgian customs would add tax to shipments like this coming in from the US?

• Alternative software for Pinnacle PCTV 100e

  - by Stijn Sanders

  I have a Pinnacle PCTV 100e external USB cable television receiver. I've been using Pinnacle's software that came with the card (TVCenter Pro) to record things at given times. Things I don't like is an extremely high CPU load, and that it doesn't seem to halt the screensaver from running when watching in full screen. Also, I was away the last two weeks, and the schedules went terribly bust. Some items were recorded hours before or after the actual scheduled time (and now I missed some shows), and some recurring schedules weren't converted into the next occurrence correctly! Is there good alternative software that would work with my PCTV 100e? (Preferalby cheap or free) I've tried VLC Player, which gets video, but no audio. I've tried MediaPortal, which crashes when trying to scan for channels. When I select a channel manually, the stored mpg has big errors in encoding and is also missing audio. There's VirtualDub, but that doesn't have ready-made scheduled-recording options. This I can conjure some scheduled scripts for, but I've noticed the sync gets awfully wrong after some time. I've tried Windows Media Center, but it doesn't seem to support the PCTV 100e.

• Windows 7 resizes desktop when I switch of a monitor

  - by Stijn Sanders

  I have a workstation with two monitors and the desktop extended over them. I have a lot of applications open (generally maximized), and I have a personal preference which application is on which monitor (let's say editors on the right, data retrieval and display on the left). I have recently upgraded to a workstation with Windows 7 and when I power off a monitor (typically when going home at the end of the day), the desktop-expand-over-monitors disables and all applications are switched to the main monitor. (Also the taskbar I keep on the left resizes to about one icon's width.) This is highly annoying, since I now spend the first minutes of work each day switching the applications back that were on the monitor on the right. Is there a way to prevent this? (It says no here.) Is there software I could install that can prevent this?

• Free MPEG cutting/cropping/editing tool

  - by Stijn Sanders

  I'm looking for a free tool to cut MPEG's that are created by recording from a USB cable receiver. There are a number of applications that do this, and some are free, but most of them take the video and audio decoded and pass them into a codec again to write the final output. I already have the MPEG's encoded the way I like, so what I need is a tool that can strip the beginning and the ending of the recording before and optionally commercial breaks, by rearranging the data within the file, not re-encoding it. Now I'm using some old software that came with the cable-receiver, but this actually re-encodes the video when exporting. I've tried VirtualDub but had major trouble getting the audio and video streams to stay in sync (and this was also re-encoding)... I found this which comes pretty close, but doesn't allow much accuracy in selecting cut positions.

• XP shared folders not accessible after BIOS changed

  - by stijn

  Here's what worked for over a year: PC A runs Windows 7, PC B runs Windows XP. Both are on the same subnet behind a router. A uses user account X, but logs in to PC B using the Administrator account. PC B is a Dell Precision 470. A known problem with these is that sometimes when plugging in their power cable they somehow loses all BIOS settings. This happened yesterday. After this happens Windows won't boot, because the default BIOS setting is 'RAID ON' while there is no RAID configured. No problem though, changing the BIOS settings to 'RAID OFF' makes it boot without problems. Note that in the meantime, nothing config-related was changed on machine A. It wasn't even on. Indeed after doing this, everything is fine. Everything includes all normal operations, remote desktop from PC A to PC B, running Synergy between A and B, accessing shared folders from B to A. But accessing the shared folders on B from A does not work any more. I tried pretty much everything I found via Google (fiddling with policies/registry kes/...) but no avail. > ping -a 192.168.2.2 Pinging A [192.168.2.2] with 32 bytes of data: Reply from 192.168.2.2: bytes=32 time<1ms TTL=128 > net view \\192.168.2.2 System error 5 has occurred. Access is denied. > net use /persistent:no K: \\A\myshare /user:A\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:192.168.2.2\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:USERNAME PASSWORD System error 86 has occurred. The specified network password is not correct. A solution to this would be great: I haven't been able to do any work since yesterday ;] update after taking the hard drive out of B and putting it in another Precision 470 with almost exactly the same hardware (at first sight, only the video card differs) the shared folders work.. Putting the disk back into A, same problem remains. Why does this depend on hardware, and more important, on which hardware?

• apache adress based access control

  - by stijn

  I have an apache instance serving different locations, eg https://host.com/jira https://host.com/svn https://host.com/websvn https://host.com/phpmyadmin Each of these has access control rules based on ip adres/hostname. Some of them use the same configuration though, so I have to repeat the same rules each time: Order Deny,Allow Deny from All Allow from 10.35 myhome.com mycollegueshome.com Is there a way to make these reusable so that I don't have to change each instance everytime something changes? Ie, can I write this once, then use it for a couple of locations? Using SetEnvIf maybe? It would be nice if I could do something like this pseudo-config: <myaccessrule> Order Deny,Allow Deny from All Allow from 10.35 myhome.com mycollegueshome.com </myaccessrule> <Proxy /jira*> AccessRule = myaccessrule </Proxy> <Location /svn> AccessRule = myaccessrule </Location> <Directory /websvn> AccessRule = myaccessrule </Directory>

  I'm using the following commands from the manual to install GIT $ tar -zxf git-1.7.2.2.tar.gz $ cd git-1.7.2.2 $ make prefix=/usr/local all $ sudo make prefix=/usr/local install but I'm receiving the following exceptions ... cache.h: At top level: cache.h:746: error: expected declaration specifiers or â...â before âtime_tâ cache.h:889: warning: âstruct timevalâ declared inside parameter list cache.h:895: warning: âstruct timevalâ declared inside parameter list cache.h:970: error: expected specifier-qualifier-list before âoff_tâ cache.h:979: error: expected specifier-qualifier-list before âoff_tâ cache.h:997: error: expected specifier-qualifier-list before âoff_tâ cache.h:1057: error: expected declaration specifiers or â...â before âoff_tâ cache.h:1063: error: expected declaration specifiers or â...â before âuint32_tâ cache.h:1064: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before ânt h_packed_object_offsetâ cache.h:1065: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âfi nd_pack_entry_oneâ cache.h:1067: error: expected declaration specifiers or â...â before âoff_tâ cache.h:1069: error: expected declaration specifiers or â...â before âoff_tâ cache.h:1070: error: expected declaration specifiers or â...â before âoff_tâ cache.h:1094: error: expected specifier-qualifier-list before âoff_tâ cache.h:1168: error: expected â)â before â*â token cache.h:1177: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âre ad_in_fullâ cache.h:1178: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âwr ite_in_fullâ cache.h:1179: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âwr ite_str_in_fullâ cache.h:1252: error: expected declaration specifiers or â...â before âFILEâ In file included from credential-store.c:2: credential.h:28: error: expected declaration specifiers or â...â before âFILEâ credential.h:29: error: expected declaration specifiers or â...â before âFILEâ In file included from credential-store.c:4: parse-options.h:115: error: expected specifier-qualifier-list before âintptr_tâ credential-store.c: In function âparse_credential_fileâ: credential-store.c:13: error: âFILEâ undeclared (first use in this function) credential-store.c:13: error: âfhâ undeclared (first use in this function) credential-store.c:17: warning: implicit declaration of function âfopenâ credential-store.c:19: error: âerrnoâ undeclared (first use in this function) credential-store.c:19: error: âENOENTâ undeclared (first use in this function) credential-store.c:24: error: too many arguments to function âstrbuf_getlineâ credential-store.c:24: error: âEOFâ undeclared (first use in this function) credential-store.c:39: warning: implicit declaration of function âfcloseâ credential-store.c: In function âprint_entryâ: credential-store.c:44: warning: implicit declaration of function âprintfâ credential-store.c:44: warning: incompatible implicit declaration of built-in fu nction âprintfâ credential-store.c: In function âmainâ: credential-store.c:132: warning: implicit declaration of function âumaskâ credential-store.c:144: error: âstdinâ undeclared (first use in this function) credential-store.c:144: error: too many arguments to function âcredential_readâ credential-store.c:147: warning: implicit declaration of function âstrcmpâ Is this because I didn't install the dependencies? apt-get install libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev How do I install them offline?

• windows 7 taskbar pin custom shortcuts to jumplist

  - by stijn

  For example I have TightVNC Viewer pinned to taskbar, it does not allow a jumplist (pinning multiple items or storing recent items). However I have a couple of shortcuts to vncviewer.exe that take arguments. Is there a way to get these in a jumplist for the vncviewer taskbar icon anyway? Found jumplist launcher already, but it's not exactly what I'm after + it's buggy (cannot add arguments to the exe)

• Windows 7 access denied to executables.. by what?

  - by stijn

  Ever since I started using Windows 7 this problem has been bothering me. From time to time I see similar questions popping up on misc forums, but never did I see an answer. Here are two scenarios that nearly always reproduce it: the explorer way with explorer, navigate to a directory containing at least one exe file go one directory up immediately delete the directory just navigated to yields Folder Acces Denied dialog stating You need permission to perform this action You require permission from Administrators to make changes to this folder, with the buttons try Again and Cancel hitting Try Again never works immediately. Waiting a minute or so and then clickig it again does work note: if in step 2 and waiting a minute or more before going up one directory, the problem does not occur and the folder can be deleted the visual studio way build a project producing an exe file run the executable then close it immediately build the project again (by changing a single character in a source file for example) yields fatal error LNK1168: cannot open /path/to/the.exe for writing note: if in step 2 and waiting a minute or more before building again, the problem does not occur some specs happens both on Windows 7 32 and 64 bit, with VS2008/2010/2011 happens on 3 different machines I do not have a virusscanner of any kind I do have a bunch of services disabled, but nothing that prevents Windows from running normally, UAC is disabled as well happens on any type of disc I always use a user account that is in the Administrators group Obviously both scenarios are very similar and extremely reproducable. So I figured some process must have the file open for some reason, and release it again later. However, using systinternal's handle -a the exe file in question never shows up. (that is the correct way to use handle, right?) So while explorer/VS are reporting they cannot access the file, handle.exe says it's not in use anywhere. This leaves me rather clueless, so I'm wondering if someone can come up with a solution: why does this happen, and how to solve it?
