• LaTeX: Left aligning without extra space between words in tables

  - by goldfrapp04

  Here is the illustrating code: \documentclass[letterpaper, 10pt]{article} \usepackage[margin=1in]{geometry} \usepackage{array} \usepackage[none]{hyphenat} \begin{document} \begin{center} \begin{tabular}{|m{4.5cm}|m{1.2cm}<{\centering}|m{8cm}|c|} \hline \centering \textbf{Course Name} & \centering \textbf{Date} & \centering \textbf{Textbook} & \centering \textbf{Grade} \tabularnewline \hline C Programming Language \& Lab & 09/2009 - 12/2009 & Brian W.

I'd like to leave only single space between words, without justify align. THANK YOU!

• MySQL : incrementing text id in DB

  - by BarsMonster

  I need to have text IDs in my application. For example, we have acceptable charset azAZ09, and allowed range of IDs [aaa] - [cZ9]. First generated id would be aaa, then aab, aac, aad e.t.c. How one can return ID & increment lower bound in transaction-fashion? (provided that there are hundreds of concurrent requests and all should have correct result) To lower the load I guess it's possible to define say 20 separate ranges, and return id from random range - this should reduce contention, but it's not clear how to do single operation in the first place. Also, please note that number of IDs in range might exceed 2^32. Another idea is having ranges of 64-bit integers, and converting integer-char id in software code, where it could be done asyncroniously. Any ideas?

• How can I compile an autotools project with statically linked dependancies?

  - by flyx

  There's an open source library I want to use. As I want to spread my software as binary package, I do not want the library to have dependancies on other libraries, so I need to link the dependancies statically. Now as the library is open source and there are no binaries provided, I compile it myself. The library uses autotools, and I didn't find any useful documentation on how to link dependancies statically. What I did try is to call the configure script with --enable-static, but this apparently only tells configure to compile a static version of the library - but what I need is a dynamic library that includes all the libraries it depends on. So, I need a way to either tell configure to link against dependancies statically, or a way to post-process the built library to include all dependancies. Can anyone tell me how to do this? Oh, and if it matters: I'm on 64bit Snow Leopard.

• Where can I find soft-multiply and divide algorithms?

  - by srking

  I'm working on a micro-controller without hardware multiply and divide. I need to cook up software algorithms for these basic operations that are a nice balance of compact size and efficiency. My C compiler port will employ these algos, not the the C developers themselves. My google-fu is so far turning up mostly noise on this topic. Can anyone point me to something informative? I can use add/sub and shift instructions. Table lookup based algos might also work for me, but I'm a bit worried about cramming so much into the compiler's back-end...um, so to speak. Thanks!

• Get DataGridView checkbox cell value?

  - by George

  Hello guys. I'm having a strange issue here. I have a 3 column datagrid that is filled by a connection with the database. So far so good. I have an extra column, of checkbox type. I need to get it's value for perfoming a bulk operation on it. Here is the catch: When all cells are selected, it works fine. But when an user selects any cell that its not the first, software gives me a object reference exception. Here is the code public List<String> GetSelected() { List<String> selected = new List<String>(); foreach(DataGridViewRow row in datagrid.rows) { if ((Boolean)row.Cells[wantedCell].Value == true) { selected.Add(row.Cells[anotherCell]); } } } I tracked down the failure to the if-test, throwing a exception, because the value of the cell is read as null. Any thougths? Thanks

• Send mail from a Windows script

  - by Jörgen Lundberg

  I would like to send mail from a script on a Windows Server 2003 Standard Edition. I think the server setup is pretty much out of the box. The mail server is an Exchange one, and when you're on the internal network you can use plain old SMTP. I have done it from my machine with Perl, but unfortunately Perl is not available on the server. Is there an easy way of doing this from a .bat-file or any other way that doesn't require installing some additional software? Edit: Thanks for the quick replies. The "blat" thingie would probably work fine but with wscript I don't have to use a separate binary. I didn't see PhiLho's post the first time I edited and selected an answer. No need for me to duplicate the code here. Just save the script to a file, say sendmail.vbs, and then call it from the command prompt like so: wscript sendmail.vbs

• API For Flex Apps To Interact

  - by dimo414

  I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to allow the app and the widgets to communicate, allowing the app to make changes to the widgets and the the widgets to notify the app when events are triggered, so that user interaction is fluid and continuous. There are a few related questions which indicate it's possible to do this by setting up event triggers and listeners. I am wondering if there is any standardized way to do this (the answers aren't very clear) or if anyone has developed a library or API to make this easier.

• Visual C++ 2008 doesn't recognize Windows declared types

  - by David Thornley

  I have a program that doesn't seem to recognize declared types in the latest U3D software. There's a line typedef BOOL (WINAPI* GMI)(HMON, LPMONITORINFOEX); which gets the error: Error 1 error C2061: syntax error : identifier 'LPMONITORINFOEX' c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 28 and a line MONITORINFOEX miMon; which gets Error 5 error C2065: 'miMon' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 Error 3 error C2065: 'MONITORINFOEX' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 The program's first non-comment statement is #include <windows.h>, which includes winuser.h, which defines these identifiers. In Visual Studio, I can right-click on them and go to the definition (a typedef) and from the typedef to the struct. WINAPI is defined in WinDef.h, so that seems to be working. There are no redefinitions of LPMONITORINFOEX or MONITORINFOEX in any other file. So, how can this be happening, and what can I do about it?

• How to study for MCTS 70-433 exam (SQL Server 2008 Database Development) and is it worth it?

  - by Mugen

  Hi, I'm working as a QA (Software Tester with 3 years of experience) and was thinking of getting some certifications for my career. I already have the ISTQB certification and was thinking of doing SCJP along with MCTS 70-433 certification (SQL Server 2008 Database Development) as the next move. So my question is this: 1) Who should go for the 70-433 certification and is it worth going for, for a career in QA? 2) What would be a good book to study for this? I'm just looking for a simple book that is written just to the point and not much bloated up such as technical bibles. Not that they aren't good but they just take up too much of time. Maybe something similar to the one written by Kathy Sierra & Bert Bates for SCJP. It is written in a very simple language and is enough to do SCJP. Edit: I'm still searching for answers to this. Thanks.

• Flash content in eLearning: one SWF vs. many?

  - by loucadro

  I am designing a Flash-based language course, and I am not sure which architecture I have to choose. The content won't be uploaded to the Internet, it will be used only locally. Possible architectures: 1) A single SWF with all the data stored internally - it seems a rather clumsy and inefficient way (or it's not?). 2) To make a Flash-based interface, and to keep the data saved in a MySQL database. It presumably allows to organize the content better, avoiding self-repetitions. The problem is that the language teacher (who is not an IT specialist) will have to install additional software to handle MySQL. 3) To make a number of separate SWF files, and to make a simple HTML-file with the index. (and some other solutions I didn't think of) Which is the right architecture, most usable for the teacher and most elegant from the IT point of view?

• How can I make an Access database readable from the web while it is open in MS Access?

  - by djdilicious

  I have a website using ASP with an MS Access DB back-end for storing mainly blog posts. My company has a very long software approval process so I am stuck with what I have (i.e. I must use Access). I use server-side javascript to retrieve posts stored in the database using OLEDB calls. Everything works fine except that I cannot read any tables from the database when it is open in the MS Access program. The page displays an error message about the file being in use. This could lead to significant downtime while I am doing any work within Access. How can I make the file readable by my ASP application while it is open in Access?

• Handover document for complete systems

  - by viraptor

  Hi, I need to create a handover document for a fairly large system consisting of all the stuff you'd expect from a telecom deployment: many servers, database clusters which copy some data between them in specific ways, tons of log files, both off-the-shelf and locally developed software, scripts, network configurations, local know-how, etc. It's really got as many sysadmin-typical elements, as development ones. The target of this document are in the first place sysadmins who take over the day-to-day operation tasks and some problem resolving, and in the second place people who want to learn about the system in general. Is there some place I can learn about how to write something like that? It could just as easily be a 10 page "what's where", as a 500 pages book about "all things telephony". Maybe it should be more than one document really. Please link some useful resources / books I could use for this task. PS: this is intended to be internal only, customer interactions etc. are out of scope here

• Forcing Windows to re-scan for drivers

  - by Martin

  As part of our software's installation, we install drivers for a required 3rd party hardware component. Currently it's up to the user to manually scan for their hardware's drivers once our installation is completed. Is there an easy way to get Windows to automatically look for the drivers we installed? If so, how does it work? Do we need to tell the OS for which hardware device we have drivers, or just that we have drivers in a certain location? Or can we just install the drivers to System32 folder and trigger a driver rescan?

• How do you get Windows Mobile Device Center to detect a Windows Phone 7 Series emulator?

  - by sweeney

  Hello, I'm running some tests and need to be able to get Windows Phone 7 Series emulator synced with an exchange account or local Outlook account via the Device Center. I'm using the unlocked version of the emulator so that i actually have a reasonable set of software on the phone to work with. When the emulator launches i expect the Device Center to detect it and start syncing (or prompt me for settings). This does not happen. I've tried adjusting the Connection Settings (COM2 and DMA) in the Device Center with no luck. Is this possible? Has anyone done it? Thanks in advance!

• How to reduce the number of points in (x,y) data

  - by Gowtham

  I have a set of data points: (x1, y1) (x2, y2) (x3, y3) ... (xn, yn) The number of sample points can be thousands. I want to represent the same curve as accurately as possible with minimal (lets suppose 30) set of points. I want to capture as many inflection points as possible. However, I have a hard limit on the number of allowed points to represent the data. What is the best algorithm to achieve the same? Is there any free software library that can help? PS: I have tried to implement relative slope difference based point elimination, but this does not always result in the best possible data representation. Thanks for your time. -Gowtham

• Dynamically setting WCF endpoint

  - by Matt

  Ive just started using WCF with silverlight and its working fine. But one thing that is bugging me is the address of the .svc. Why is it statically set in the .config? Would it be possible to set it when creating an instance of the proxy class? And if so, is there a way to set it to the current address? Our software will be deployed on many different domain and we cant change the config every time. The svc will always be in the same domain as the silverlight page. Thanks.

• Is it me or is developing web based data entry GUIs a big pain?

  - by GregH

  Maybe it's me or maybe it isn't. I don't have a huge amount of experience of developing web based data entry software but do have some. I used to do it quite a bit years ago. Used to use Oracle Forms, Visual Studio, various 4th generation languages, and performing the user interface layout used to be a snap. Now doing the user interface for developing web applications seems to be a huge pain in the rear. Just trying to get text entry fields and widgets to go where they are supposed to go on the screen is a total pain. You have to know Javascript, CSS, JQuery, HTML, etc. There must be an easier way to develop data entry forms that produce the needed underlying code for a web page. Maybe I'm just not looking in the right place. There must be some WYSIWYG GUI development tools for the web for developing data entry forms out there. Anybody know of any?

• How do I create an ant builder file (build.xml) for an existing Java project?

  - by Amir Rachum

  Hi all, I am working on an Java assignment for a software design course in my university. It's not really complicated and it includes some classes, interfaces and jUnit test cases. We we're now told we should supply a build.xml file as an input for an ant builder. I have never heard of or used ant before. I also saw Eclipse supports it. My question is - What does build.xml does? How does Eclipse builds my project and why not do the same instead of using ant? And most important - how to create this file with Eclipse? Thanks.

• I need to debug my BrowserHelperObject (BHO) (in C++) after a internet explorer 8 crash in Release m

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• Does normalization really hurt performance in high traffic sites?

  - by Luke101

  I am designing a database and I would like to normalize the database. I one query I will joining about 30-40 tables. Will this hurt the website performance if it ever becomes extremely popular? This will be the main query and it will be getting called 50% of the time. The other queries I will be joining about 2 tables. I have a choice right now to normalize or not to normalize but if the normalization becomes a problem in the future i may have to rewrite 40% of the software and it may take me a long time. Does normalization really hurt in this case? Should I denormalize now while I have the time?

• C# VS 2008 Build Configurations - using different classes for different builds

  - by evan

  I'm writing an application which has two classes that provide basically the same functionality but for different situations. I'd like to have three versions of the software - one where the user can change an ini file to configure the program to use one of the two classes, and then one version that only uses one of the two classes. Right now I have it working via an ini file, but I'd like to be able to build versions that don't include the code for the unneeded class at all. What is the best way to go about this? My current line of thinking is that since both classes derive from a common interface I'll just add a compile time conditional that looks at the active build configuration and decides whether to compile that class. What is the syntax to do that? Thanks in advance for your help and input!
