  • Python vs all the major professional languages [closed]

    - by Matt
    I've been reading up a lot lately on comparisons between Python and a bunch of the more traditional professional languages - C, C++, Java, etc, mainly trying to find out if its as good as those would be for my own purposes. I can't get this thought out of my head that it isn't good for 'real' programming tasks beyond automation and macros. Anyway, the general idea I got from about two hundred forum threads and blog posts is that for general, non-professional-level progs, scripts, and apps, and as long as it's a single programmer (you) writing it, a given program can be written quicker and more efficiently with Python than it could be with pretty much any other language. But once its big enough to require multiple programmers or more complex than a regular person (read: non-professional) would have any business making, it pretty much becomes instantly inferior to a million other languages. Is this idea more or less accurate? (I'm learning Python for my first language and want to be able to make any small app that I want, but I plan on learning C eventually too, because I want to get into driver writing eventually. So I've been trying to research each ones strengths and weaknesses as much as I can.) Anyway, thanks for any input

  • Android newbie installing Eclipse, having issues....

    - by Jeff
    I am a web developer, new to app development and Java/Android. I am about to follow some tutorials to get started learning but I'm running into a wall. The Android dev site says the recommended way to build Android apps is in Java using the Eclipse plug in. So I downloaded Eclipse Classic and unzipped it on to get this error: "A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: /Users//Desktop/eclipse/Eclipse.app/Contents/MacOS/jre/bin/java java in your current PATH" Any idea what the issue is and how I can fix it? Again, newbie to java, jre, android, so I apologize if this question has already been asked. In my research I've discovered that most of the posts or solutions I've found are tough for me to follow. There's always a few unclear items that are probably prohibiting me from getting the answer I need. So I'm hoping someone can walk me through installing or configuring whatever I need to regarding Java so I can continue installing Eclipse and begin learning. I should probably note that I'm on Mac OSX 10.6.6 Snow Leopard. Please let me know if you need any other info. Thanks so much in advance for any and all help!!!

  • PC to Macbook Pro Transition - Getting (re)started?

    - by Torus Linvald
    I'm in my second computer science course right now. I've enjoyed programming so far, but really have just scraped my way by. I've not done much programming outside of required class work. For similar reasons, I never really invested in downloading/learning software to help me program (IDE's, editors, compilers, etc). I know it sounds tedious, but my current setup is: notepad++ for coding; Filezilla to transfer .cpp & .h files to school's aludra/unix and compiling; unix tells me where my bugs are and I go back to notepad++ to debug; repeat until done. This isn't fun - and I know it could be easier. But I put it off knowing that I was soon going to switch to a Mac. And, tomorrow, I'm switching. So... How should I set up my Macbook for the best programming experience? What IDEs and editors and debuggers and so on should I download? How will Mac programming differ from PC? I'm open to all ideas and comments, even the most basic. (Background - I'm learning/programming in C++ right now. Next semester, my classes switch to Java. I'm also going to take a class in web development, with HTML/CSS/Javascript/PHP. My new laptop will be a late 2009 Macbook Pro with Leopard, or maybe Snow Leopard. Free would be preferrable for all programs.) Thank you all.

  • How can I change the default startup directory for cmd.exe?

    - by Nano HE
    Hi. My Procedure last day as below Click Start, Run and type Regedit.exe Navigate to the following branch: HKEY_CURRENT_USER \ Software \ Microsoft \ Command Processor In the right-pane, double-click Autorun and set the startup folder path as its data, preceded by “CD /d “. If Autorun value is missing, you need to create one, of type REG_EXPAND_SZ or REG_SZ in the above location. Example: To set the startup directory to D:\learning\perl, set the Autorun value data to CD /d D:\learning\perl Then I clicked Start, run and type cmd. It successfully. I could do perl practice more conveniently now. But today, I find when I try to build my Visual Studio 2005 solution which included some Pre-build event Command like this: perl.exe MyAppVersion.pl perl.exe AttrScan.pl It doesn't work. Show error: can't find the path. I check the environment variable setting and find the variable-path and it's value-c:\perl\bin\; still exist. Finially, I try to removed the Regedit.exe configuration "Autorun" value and test again. The issue fixed. I only changed the default startup directory for cmd.exe command. Why the pre-build event perl command was impacted? (I am using winxp and activePerl 5.8)

  • Looping through a method without for/foreach/while

    - by RichK
    Is there a way of calling a method/lines of code multiple times not using a for/foreach/while loop? For example, if I were to use to for loop: int numberOfIterations = 6; for(int i = 0; i < numberOfIterations; i++) { DoSomething(); SomeProperty = true; } The lines of code I'm calling don't use 'i' and in my opinion the whole loop declaration hides what I'm trying to do. This is the same for a foreach. I was wondering if there's a looping statement I can use that looks something like: do(6) { DoSomething(); SomeProperty = true; } It's really clear that I just want to execute that code 6 times and there's no noise involving index instantiating and adding 1 to some arbitrary variable. As a learning exercise I have written a static class and method: Do.Multiple(int iterations, Action action) Which works but scores very highly on the pretentious scale and I'm sure my peers wouldn't approve. I'm probably just being picky and a for loop is certainly the most recognisable, but as a learning point I was just wondering if there (cleaner) alternatives. Thanks. (I've had a look at this thread, but it's not quite the same) http://stackoverflow.com/questions/2248985/using-ienumerable-without-foreach-loop

  • Find XmlNode where attribute value is contained in string

    - by bflemi3
    I have an xml file... <?xml version="1.0" encoding="UTF-8"?> <items defaultNode="1"> <default contentPlaceholderName="pageContent" template="" genericContentItemName="" /> <item urlSearchPattern="connections-learning" contentPlaceholderName="pageContent" template="Connections Learning Content Page" genericContentItemName="" /> <item urlSearchPattern="online-high-school" contentPlaceholderName="pageContent" template="" genericContentItemName="" /> </items> I am trying to find the first node where the urlSearchPattern attribute is contained in the string urlSearchPattern. Where I'm having trouble is finding the nodes where the attribute is contained in the string value instead of the string value be contained in the attribute. Here's my attempt so far. This will find the firstOrDefault node where the string value is contained in the attribute (I need the opposite)... string urlSearchPattern = Request.QueryString["aspxerrorpath"]; MissingPageSettingsXmlDocument missingPageSettingsXmlDocument = new MissingPageSettingsXmlDocument(); XmlNode missingPageItem = missingPageSettingsXmlDocument.SelectNodes(ITEM_XML_PATH).Cast<XmlNode>().Where(item => item.Attributes["urlSearchPattern"].ToString().ToLower().Contains(urlSearchPattern)).FirstOrDefault();

  • Listing all objects that share a common variable in Javascript

    - by ntgCleaner
    I'm not exactly sure how to ask this because I am just learning OOP in Javascript, but here it goes: I am trying to be able to make a call (eventually be able to sort) for all objects with the same variable. Here's an example below: function animal(name, numLegs, option2, option3){ this.name = name; this.numLegs = numLegs; this.option2 = option2; this.option3 = option3; } var human = new animal(Human, 2, example1, example2); var horse = new animal(Horse, 4, example1, example2); var dog = new animal(Dog, 4, example1, example2); Using this example, I would like to be able to do a console.log() and show all animal NAMES that have 4 legs. (Should only show Horse and Dog, of course...) I eventually want to be able to make a drop-down list or a filtered search list with this information. I would do this with php and mySQL but I'm doing this for the sake of learning OOP in javascript. I only ask here because I don't exactly know what to ask. Thank you!

  • C vs C++ function questions

    - by james
    I am learning C, and after starting out learning C++ as my first compiled language, I decided to "go back to basics" and learn C. There are two questions that I have concerning the ways each language deals with functions. Firstly, why does C "not care" about the scope that functions are defined in, whereas C++ does? For example, int main() { donothing(); return 0; } void donothing() { } the above will not compile in a C++ compiler, whereas it will compile in a C compiler. Why is this? Isn't C++ mostly just an extension on C, and should be mostly "backward compatible"? Secondly, the book that I found (Link to pdf) does not seem to state a return type for the main function. I check around and found other books and websites and these also commonly do not specify return types for the main function. If I try to compile a program that does not specify a return type for main, it compiles fine (although with some warnings) in a C compiler, but it doesn't compile in a C++ compiler. Again, why is that? Is it better style to always specify the return type as an integer rather than leaving it out? Thanks for any help, and just as a side note, if anyone can suggest a better book that I should buy that would be great!

  • Abstract Design Pattern implementation

    - by Pathachiever11
    I started learning design patterns a while ago (only covered facade and abstract so far, but am enjoying it). I'm looking to apply the Abstract pattern to a problem I have. The problem is: Supporting various Database systems using one abstract class and a set of methods and properties, which then the underlying concrete classes (inheriting from abstract class) would be implementing. I have created a DatabaseWrapper abstract class and have create SqlClientData and MSAccessData concrete class that inherit from the DatabaseWrapper. However, I'm still a bit confused about how the pattern goes as far as implementing these classes on the Client. Would I do the following?: DatabaseWrapper sqlClient = new SqlClientData(connectionString); This is what I saw in an example, but that is not what I'm looking for because I want to encapsulate the concrete classes; I only want the Client to use the abstract class. This is so I can support for more database systems in the future with minimal changes to the Client, and creating a new concrete class for the implementations. I'm still learning, so there might be a lot of things wrong here. Please tell me how I can encapsulate all the concrete classes, and if there is anything wrong with my approach. Many Thanks! PS: I'm very excited to get into software architecture, but still am a beginner, so take it easy on me. :)

  • Xorg server won't start after fresh install of Debian 5.04, screen goes blank (Intel Atom D510(Pinet

    - by Kamil Zadora
    Hello, I have installed Debian 5.04 Lenny on my new Intel D510MO motheboard. I fixed some issues with incorrect drive mapping (for some reason during installation my hdd was on sdb, after a restart it is under sda - fixed in grub), and now I am struggling with getting graphical enviroment up and running, I installed the graphical enviroment using the Debian installer. I am not an linux expert by any means, I assume that I need to edit the xorg.conf file. Any hints appreciated! UPDATE1: No change after dpkg-reconfigure xserver-xorg Here is my current xorg.conf: # xorg.conf (X.Org X Window System server configuration file) # # This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database. # # Edit this file with caution, and see the xorg.conf manual page. # (Type "man xorg.conf" at the shell prompt.) # # This file is automatically updated on xserver-xorg package upgrades *only* # if it has not been modified since the last upgrade of the xserver-xorg # package. # # If you have edited this file but would like it to be automatically updated # again, run the following command: # sudo dpkg-reconfigure -phigh xserver-xorg Section "InputDevice" Identifier "Generic Keyboard" Driver "kbd" Option "XkbRules" "xorg" Option "XkbModel" "pc105" Option "XkbLayout" "pl" EndSection Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" EndSection Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" EndSection UPDATE2: I have installed vnc4server package.

  • Why does my Intel HDA onboard sound card not have a "Mix" device / channel?

    - by Hanno Fietz
    I want to be able to record what my sound card outputs on the speakers / headphones. This question is all over the interwebs again and again, and there seem to be two outcomes: in your selection of audio input devices, there's a device called "Stereo Mix", or similar, which is the "loopback" device for audio. Choose that in your recording tool and you're done. there's no such device and only speculative posts about why that may be. Now, I'm using ALSA and an Intel HDA chipset on my mainboard under Kubuntu Karmic. I have some 5-10 output channels and "Mic", "Front Mic" and "Line" for input. All of those are available in KMix, Audacity and other software. No "loopback" / "Mix" / whatever. Do I have to get some driver / kernel module set up ALSA in some way set up my system configuration in some way use a software solution (such as JACK) I had a look at JACK, and found it rather hard to understand, it's either an expert tool or just clumsy, I couldn't say. At least, I wasn't able to figure out how to achieve what I wanted. One of my problems seems to be that I don't understand where and how the mixing happens. Are there sound cards which just aren't able to do it? Why does the sound card matter at all, since I could in theory grab the data stream at some point before it goes to the hardware, right?

  • How to use Salt Stack with minions all behind NAT (not publicly accessible, default salt ports not open)?

    - by MountainX
    Can Salt Stack minions communicate with the salt master from behind NAT/Firewalls, etc., using standard ports that would be open be default in all consumer NAT routers (and without the minions having a public DNS record or static IP)? I'm working my way through my first salt tutorial, and this is where I'm stuck. I am able to configure iptables on the Ubuntu salt-master. But I have no control over the routers/NAT that the minions will sit behind. So far I tried these settings: /etc/salt/master: publish_port: 465 ret_port: 443 /etc/salt/minion: master_port: 465 That did not work. Background: I have a custom developed application presently running on about 40 Kubuntu laptops (& more planned). Every few months I have to update the application. (Often this just amounts to replacing a .jar file, which requires root permissions.) I also have to run Ubuntu updates and a few other minor things. I've been doing it manually, one by one, using Team Viewer to log into each client. I would like to dramatically improve this process. The two options I'm aware of are either: use reverse ssh tunnels and bash scripts. I tested this and it works. But I don't get any of the reporting, etc., I would get with Salt Stack. use Salt Stack (or similar) management tool. But I need a really simple tool. I can't invest any time in a big learning curve. I looked at Puppet and a bunch of related tools. The only one I found that looked simple enough for me (so far) was Salt Stack. But I'm stuck now because my minion can't reach the salt-master, as stated above. I appreciate suggestions.

  • Replacing DropBox with: Amazon S3 + SSL + GPG/TrueCrypt + Mounting on OSX ??

    - by Matt Rogish
    So, right now we're using DropBox to share various data files around between approximately 10 Mac OS X systems. However, we already have an S3 account and everyone on the lowest DropBox plan of $10/mo seems too expensive. We'd like to avoid any kind of local storage (share a disk on a desktop or something) since we're a geographically distributed team). So, I am contemplating something that would allow us to replace DropBox with our own home-grown solution. We are all fairly technical people and/or smart enough to follow some steps, so if it's not as "user friendly" as DropBox we're all comfortable with that. There are plenty of docs out there that have bits and pieces of what I want but some of the tools don't seem to fit the requirements: Transport security via SSL to the bucket Encryption of bucket contents Bi-directional syncing Most of the scripts I can find on the internet use "duplicity" which appears to fail #1 (it doesn't look like duplicity supports SSL to S3 - the docs don't state but the protocol looks plain old http http://www.nongnu.org/duplicity/duplicity.1.html#sect6 ) Many scripts use gpg to encrypt files. This seems like it could work, however I have to make sure that each OSX client is able to use the same key to encrypt and decrypt files (key management is left to me to manage). FTP and other client-based apps don't seem to support this at all. Finally, most of the scripts use one-way replication, e.g. using Amazon S3 as a simple backup store. As we'd be using Amazon S3 as the "repository" they fail this one. Whew. So, I'd love a single tool that does this but after an exhaustive search I don't think one exists. In my mind, the magical tool would be some combination of TrueCrypt and rsync. I'd be happy just knowing which tools out there can fulfill my 3 requirements, after that I can stitch together the rest. Any thoughts? THANKS!

  • Cant access Dell BMC IPMI Over IP

    - by Bobb
    I have Dell R210 with iDRAC BMC (new name for old BMC). Which is on-board feature with shared NIC (I believe). Server is on colocation and I didnt set it up before sent there... So I asked for the remote hands to setup IPMI Over IP. They enabled it, set the IP and everything. The IP is different than main box IP. Also the box is cabled to NIC1 and the BMC supposed to share it (am I right?) I can see new IP in the Open Server Administrator (installed on the box). I tried Supermicro IPMI tool and I tried Dell ipmish.exe command like this ipmish -ip xxx -u root -p calvin sysinfo gives BMC is not detected What could be wrong? is there a diagnostics tool I can try? It must be something obvious. I just never used things like that before.... P.S. I read something about encryptions key in the Dell docs. But I understand that is for encrypted IPMI 2.0 and ipmish can use IPMI 1.5 without encryption.

  • How to construct SELinux rules for a Glassfish server

    - by tronda
    I'm running Glassfish 3.1 on a CentOS 6 solution and by default SELinux is enabled. I have installed Sun's JDK version 1.6.0_29 on the server and extracted the Glassfish 3.1.1 to /opt/glassfish-3.1.1 with a link /opt/glassfish pointing to the latest Glassfish version. I've also created a system user named glassfish with a home directory /home/glassfish. When running with SELinux enabled I get all sorts of errors. For instance I'm not able to create the domain. I kind of like the concept of SELinux, and would like to be able to have SELinux enabled. I have the following requirements for the Glassfish server: Listening to port 8080 and 8081 Other ports 7676: JMS 8686: JMX monitoring, 4848: Admin console Forwarding from apache to Glassfish through mod_jk and port 8009 Starting OpenMQ as an separate process which listens to 7676 and it's JMX monitoring port 7776 Able to read and write files at a specified area (different from home directory) Able to use /tmp/ for temporary files I am aware of the audit2allow tool when running in permissive mode, but I struggle with understanding the rules that is generated from this tool, and thought that setting up these rule manually the first time would help me understand the SELinux rules better than the simplistic examples that I've seen so far. Can someone with SELinux experience help me form these SELinux rules with comments describing each part of the rules?

  • What is Apache Synapse?

    - by Aren B
    My website keeps getting hit by odd requests with the following user-agent string: Mozilla/4.0 (compatible; Synapse) Using our friendly tool Google I was able to determine this is the hallmark calling-card of our friendly neighborhood Apache Synapse. A 'Lightweight ESB (Enterprise Service Bus)'. Now, based on this information I was able to gather, I still have no clue what this tool is used for. All I can tell is that is has something to do with Web-Services, and supports a variety of protocols. The Info page only leads me to conclude it has something to do with proxies, and web-services. The problem I've run into is that while normally I wouldn't care, we're getting hit quite a bit by Russian IPs (not that russian's are bad, but our site is pretty regionally specific), and when they do they're shoving wierd (not xss/malicious at least not yet) values into our query string parameters. Things like &PageNum=-1 or &Brand=25/5/2010 9:04:52 PM. Before I go ahead and block these ips/useragent from our site, I'd like some help understanding just what is going on. Any help would be greatly appreciated :)

    First of all my setup is a VPS running Windows 2003 Server with multiple domains on it IIS 6, Plesk IsapiRewrite4.ini RewriteLogLevel 3 RewriteCond %{HTTP_HOST} ^mydomain.com$ RewriteRule ^/(.*)$ http://www.mydomain.com/$1 [R] This is one of their basic examples. Ionic is installed and setup proper because if I use another rule (a simpler one ... like the one following) it works instant # IsapiRewrite4.ini # RewriteLogLevel 3 # # This ini file illustrates the use of a redirect rule. # Any incoming URL that starts with an uppercase W # will be redirected to the specified server. RewriteRule ^/(W.*)$ http://server.dyndns.org:7070/$1 [R] This one works in the TestDriver tool and none of them gives any error or warnings in TestParse tool, but it doesn't do a thing on the webserver... The fact that one rule works means that the isapi module works. I am using the last version.

  • Verification of files on backup media - after the backup

    - by Greg Sansom
    I have a system in place where I back up my work files daily to a portable hard drive. I actually have two portable hard drives - one is stored off-site and I swap them regularly. I also keep my family photos and other historical files backed up, but I only back the photos up occasionally (ie when I have new photos). The backup media is for backup only, and it is unlikely I will ever read the files from the backup media unless a disaster occurs and I lose the master. It worries me that my backed up files could become corrupt without me knowing it. It is also feasible that my master files could become corrupt, and eventually the corrupt files would be replicated to the backup media. I'm currently using Cobian Backup, but I'm open to alternatives. Is there a tool I can use to confirm that the backed up files are identical to the files that were first copied? I know it would be possible to generate a checksum and periodically validate the backup files against the original checksum, but I'm looking for a tool which will do this automatically.

  • How do I easily repair a single unreadable block on a Linux disk?

    - by Nelson
    My Linux system has started throwing SMART errors in the syslog. I tracked it down and believe the problem is a single block on the disk. How do I go about easily getting the disk to reallocate that one block? I'd like to know what file got destroyed in the process. (I'm aware that if one block fails on a disk others are likely to follow; I have a good ongoing backup and just want to try to keep this disk working.) Searching the web leads to the Bad block HOWTO, which describes a manual process on an unmounted disk. It seems complicated and error-prone. Is there a tool to automate this process in Linux? My only other option is the manufacturer's diagnostic tool, but I presume that'll clobber the bad block without any reporting on what got destroyed. Worst case, it might be filesystem metadata. The disk in question is the primary system partition. Using ext3fs and LVM. Here's the error log from syslog and the relevant bit from smartctl. smartd[5226]: Device: /dev/hda, 1 Currently unreadable (pending) sectors Error 1 occurred at disk power-on lifetime: 17449 hours (727 days + 1 hours) ...

    It appears that UAC is broken cant move/delete some file/folders, when asked to use administrative right (and say yes) it shows the loading bar and then nothings gets moved/deleted, no error whatsoever opened control panel, user account and when i click on any option with the Shield (administrative rights) the mouse changes to loading and thengo back to normal, not opening any menu or showing any error Already done a sfc /scannow , no errors found Already used Microsoft's Fix it, reclycle bin broken and repaired, still the same error Used microsoftaccounts tool , this are the errors i got: Problem with microsoft account policy... <- this is the problem (didint fix) Trust this PC <- loop of redirections, cant get to trust this pc (only one with w8) Problems witht sytem registration : i think it is because of the soft system reset Some setting have sync turned off : i never configured anything to sync Rootcauses found and created logs : would like to know where the logs are saved... had to use a ".reg" file to change uac setting to never notify, thinking it would fix this, no, it stoped asking though, i can still open a cmd with Administrative rights, but cant access to UAC settings Accesed Administrator account (net user administrator /active:yes)and even with that account could change any settings so there it is, dont know what else to do in the moment (this pc broke with 8.1 update and was restored to factory configuration, it broke several drivers and kept most of the registry entries, i cant find the cause of this problem. other info: i tried to delete a file in a program folder and couldnt, downloaded unlocker to check first if it was permissions but no, it showed me a msg telling me that there wasnt any error, and if i would like to delete it, clicked on yes, and it did delete it, what amuses me is that i cant without this tool, not even using the feature that takes over ownership Edit: wow, in a not crappy pc chkdsk is fast, completed with no errors found : /

  • Atlassian Crucible very slow on large repository

    - by Mitch Lindgren
    Hi everyone, My company has been running a trial of Atlassian Crucible for some months now. For repositories where it's working properly, users have given very positive feedback about the tool. The problem I'm having is that we have several different projects, each with its own repository, and some of those repositories are very large. One repository in particular has a large number of branches and probably around 9,000 files per branch. Browsing that repository in Crucible is extremely slow. Crucible is running on a CentOS VM. The VM has 4GB of RAM, and I've set Crucible's maximum at 3GB, of which it is currently using 2GB. I've brought this up in a support ticket with Atlassian, and they suggested the following: In particular because you have a rather large SVN repository you will likely find that Fisheye will be creating a large index file on disk. To help improve performance a few things you can try are: Increasing the available memory available to Fisheye (see the document above). Migrating to an external database: confluence.atlassian.com/display/FISHEYE/Migrating+to+an+External+Database Excluding files and directories from your index that aren't needed: confluence.atlassian.com/display/FISHEYE/Allow+(Process) (Sorry for not hyperlinking; don't have the rep.) I've tried all of these things to an extent, but so far none have helped greatly. I was originally running Crucible on a Windows box with 2GB of RAM using the built in HSQL DB. Moving to MySQL on CentOS saw a performance increase for some repositories, and made Crucible much more stable, but did not seem to help much with our biggest repository. There are only so many files/branches I can exclude from indexing while maintaining the tool's usefulness. That being the case, does anyone have any tips on how to speed up Crucible on large repositories, without investing in insanely powerful hardware? Thanks! Edit: To clarify, since I didn't mention it explicitly above, I am using FishEye.

  • How to connect to local instance of SQL Server 2008 Express

    - by Billy Logan
    I just installed SQL Server 2008 Express on my windows 7 machine. I previously had 2005 on here and used it just fine with the old SQL Server Management Studio Express. I was able to connect with no problems to my PC-NAME\SQLEXPRESS instance. I uninstalled 2005 and SQL Server Management Studio Express. I then installed SQL Server 2008 Express on my machine and elected to have it install SQL Server Management Studio. Now, when I try to connect to PC-NAME\SQLEXPRESS (with Windows Authentication, like I always did), I get the following message: Cannot connect to PC-NAME\SQLEXPRESS. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=-1&LinkId=20476 When I went to the help link it mentions, the help page suggests the following: * Make sure that the SQL Server Browser service is started on the server. * Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections. I did try starting the SQL Server Browser, but don't see that the Surface Area Configuration is installed with this express version. I had seen another user with an almost exact same issue that was missing the database engine on install. If that were the case how could i test for that and where would i go to download that install. Thanks in advance, Billy
