• macdeployqt and third party libraries

  - by user338170

  I've got an application project that depends on a couple of shared libraries that I have created myself. According to the Qt 4.6 documentation "Deploying an Application on Mac OSX": Note: If you want a 3rd party library to be included in your application bundle, then you must add an excplicit lib entry for that library to your application's .pro file. Otherwise, the macdeployqt tool will not copy the 3rd party .dylib into the bundle. I have added lib entries to my application's .pro file but the libraries that I have written do not get copied into the bundle when I execute macdeployqt. I have the following in my .pro file: LIBS += -L../Libraries -lMyLib Everything builds okay, its just when I try to run from the bundle that I run into problems i.e. "image not found" errors. Is there a bug in macdeployqt or do I have to something more to my .pro file?

So far, I've done the following: Create a new project; an iPhone OS window based app. Go to target info- under packaging, change the wrapper extension from app to framework Go to Action-new build phase - copy headers. Change roles of headers to 'public' From my application, I add the framework to the frameworks group.

• SQL select statement

  - by kwokwai

  Hi all, I got a Table which has two fields: Point, and Level, with some sample data as follows: ----------------------- Point | Level ----------------------- 10 | Level 1 20 | Level 2 30 | Level 3 40 | Level 4 Suppose that there is a user who has 25 points, to find the Level in which this user is in, the Select statement I used was: Select Level from Table where Point < 30 AND Point > 20; But the Select SQL ststament is a hard-copy one where you can see the ponts 30 and 20 are fixed. I want to alter the Select statement so that the new SQL Select statement can be applied to all users with different points, but I don't know how to do it.

• How do I pipe the Java console output to a file?

  - by Ced

  I found a bug in an application that completely freezes the JVM. The produced stacktrace would provide valuable information for the developers and I would like to retrieve it from the Java console. When the JVM crashes, the console is frozen and I cannot copy the contained text anymore. Is there way to pipe the Java console directly to a file or some other means of accessing the console output of a Java application? Update: I forgot to mention, without changing the code. I am a manual tester. Update 2: This is under Windows XP and it's actually a web start application. Piping the output of javaws jnlp-url does not work (empty file).

• Upload a file to SharePoint through the built-in web services

  - by Andy McCluggage

  What is the best way to upload a file to a Document Library on a SharePoint server through the built-in web services that version WSS 3.0 exposes? Following the two initial answers... We definitely need to use the Web Service layer as we will be making these calls from remote client applications. The WebDAV method would work for us, but we would prefer to be consistent with the web service integration method. There is additionally a web service to upload files, painful but works all the time. Are you referring to the “Copy” service? We have been successful with this service’s CopyIntoItems method. Would this be the recommended way to upload a file to Document Libraries using only the WSS web service API? I have posted our code as a suggested answer.

• Avoiding problem of overwriting files which are in use

  - by zaf

  For example on a high traffic web server. To reduce problems when switching a file I usually rename the old file out and then rename in the new file. I was told some time ago that renaming a file does not change the 'inode data' so that processes reading the file can keep doing so without glitches. And, of course, rather than copying in the new file it is faster and safer to rename a temp copy. Is this still best practice and if not what do you do?

• question about frequency of updating access

  - by I__

  i have a table in an access database this access database is used on a regular basis, basically from 9-5 someone else has a copy of this exact table. sometimes records are added, sometimes deleted, and sometimes data within the records is updated. i need to update the access database table with the offsite table every hour or so. what is the best algorithm of updating the data? there are about 5000 records. would it severely lock up the table for a few seconds every hour? i would like to publicly apologize for my rude comment to david fenton

• How to handle packages provided Java using Eclipse P2

  - by ctron

  I got some OSGi bundles in binary form that declare dependencies to bundles like "org.ietf.jgss" which are provided by Java itself. P2 detects these dependencies and when I try to install the product later using the P2 director application the installation fails since no bundle provides these packages. But if I use the P2 product build I get a complete installed product that I can use. My problem is that I don't want to create product files and build for each variation of the application. So tried the approach to copy all P2 repositories in order to install the product on the target system using the P2 director. So how do I handle dependencies to packages provided by Java and how to I "convince" P2 to ignore these packages if they are provided by Java itself. Thanks for helping.

• Deploy maven generated site on Google Code svn?

  - by xamde

  Using a google code svn as a basic maven repository is easy. However, using mvn site:deploy efficiently on google code seems hard. So far, I found only these solutions: * Deploy to a local file:/// and use a PERL script to delete the old and copy the new * Use wagen-svn to deploy. This is very slow (hours!) and does not delete old files * Plus all mime-types are wrong I am looking for a solution that allows new developers in my projects to check out the current source and just use it, without requiring to install PERL or learn weird steps to perform or wait hours.

• How do I backup my C++ Builder component installation?

  - by Gary Benade

  Hi I finally have my c++ Builder 2010 installation the way I want it, with all my components upgraded and installed. (touch wood) I have been working with c++builder since version 1 and I know from countless previous traumatic experiences that this state of affairs could change in an instant. I would like to backup the installation and component set. Is there a way to do this? A tool perhaps? A menu command that I have maybe missed all these years? I don't want to have to reinstall all the components from the bpl source again. I make nightly backup images of my entire drive, I would like to do this for c++builder only if possible. If it's a matter of simply copying files, which files would I need to copy? Are there entries in the registry that would need to be restored? Thanks in advance for any thoughts and suggestions

• How can I send an automated reply to the sender and all recipients with Procmail?

  - by jchong

  I'd like to create a procmail recipe or Perl or shell script that will send an auto response to the original sender as well as anybody that was copied (either To: or cc:) on the original email. Example: [email protected] writes an email to [email protected] and [email protected] (in the To: field). Copies are sent via cc: to [email protected] and [email protected]. I'd like the script to send an auto response to the original sender ([email protected]) and everybody else that was sent a copy of the email ([email protected], [email protected], [email protected] and [email protected]). Thanks

• Addressing "Access Denied" Exception with WMI Calls

  - by Joe

  I'm getting an exception with a message of "Access Denied" when executing against a WMI request. Some WMI requests appear to require higher security privileges than others. Ultimately my goal is to monitor process launches within the system and log. Regardless if there is a better approach, its now become a vendetta in getting this WMI approach to work. I've attempted the code at Security Tools - WMI Programming Using C#.Net and still receive the exception. If you copy the code found in the blog entry you can reproduce my issue. Another post on a similar topic can be found at link text but again, try the code and you'll the see the same security exception. How do I permit my code to execute these WMI requests? I'm running on Windows 7 Pro and VS 2010 in a new C# command line project.

• Is using GET with a tokenID for security a good idea?

  - by acidzombie24

  I was thinking about this and it appears POST only a little less vulnerable and somewhat harder (do to requiring the user to click something). I read about token ids and double submitted cookies and i am not sure what the difference is http://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29_Prevention_Cheat_Sheet#Disclosure_of_Token_in_URL http://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29_Prevention_Cheat_Sheet#Double_Submit_Cookies Right now i have the user id (PK in my table) and a session id so you cant simply change your cookie ID and act like someone else. Now it seems like i put the session id as a token in each of my forms and check them bc attackers cant guess these tokens. However i dislike the idea of putting the session id into the page for ppl to see. But really, is there a problem with that? short of having the user copy/pasting the html is there any attacks that can happen due to the session id being in plain view in html?

• How do I troubleshoot an IPsec tunnel (from a cellular router to a public server)?

  - by Hanno Fietz

  I'm new to IPsec and struggling with a setup that might soon be widely used in our operations (provided I do understand it, eventually...). A cellular router (blackbox by netModule, from its log messages it seems to be running Linux and OpenSwan) connects a sensor network on customers' sites with our public server. We need to be able to connect into the local network, so I had the cell provider give me a public IP (a dynamic one). The way their setup works, the public IPs only allow IPsec traffic. I set up OpenSwan on our Ubuntu server (running Jaunty). This is my connection config from /etc/ipsec.conf: conn gprs-field-devices left=my.pub.lic.ip [email protected] #leftsubnet=192.168.1.129/25 right=%any [email protected] #rightsubnet=192.168.1.1/25 #rightnexthop=%defaultroute auto=add On the router, all I have is the Web UI, in which I made the following settings: "Remote endpoint": public IP of server, same as "left" above "Local Network Address": 192.168.1.1 "Local Network Mask": 255.255.255.128 "Remote Network Address": 192.168.1.129 "Remote Network Mask": 255.255.255.128 The pluto process on the server is listening for connections on port 500. It can't open a tunnel, obviously, because it doesn't know at which IP the client is. I set up a passphrase as PSK for @field.econemon.com in /etc/ipsec.secrets and also configured it in the router (which doesn't seem to support certificates). My problem is, nothing happens. The router just says, IPsec is "down". When I copy-paste the IP into ipsec.conf (for "right="), and ask the server to ipsec auto --up gprs-field-devices, it just hangs until I press Ctrl-C. Is there anything wrong with my setup? How can I debug this further? My router gives the following loglines that seem related, but don't tell me anything: Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.d/hostkey.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.d/netbox0.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: "netbox00" #1: initiating Main Mode Feb 21 23:08:20 Netbox daemon.err ipsec__plutorun: 104 "netbox00" #1: STATE_MAIN_I1: initiate Feb 21 23:08:20 Netbox daemon.err ipsec__plutorun: ...could not start conn "netbox00" Feb 21 23:08:22 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: ignoring informational payload, type NO_PROPOSAL_CHOSEN Feb 21 23:08:22 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: received and ignored informational message Feb 21 23:08:28 Netbox user.warn parrot.system_controller[762]: IPSECCTRLR: Tunnel 0 is down for 0 seconds Feb 21 23:08:40 Netbox user.warn parrot.system_controller[762]: IPSECCTRLR: Tunnel 0 is down for 10 seconds Feb 21 23:08:52 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: ignoring informational payload, type NO_PROPOSAL_CHOSEN

• Trying to create text boxes dynammically and remove them

• SQL Server 2008 - Script Data as Insert Statements from SSIS Package

  - by Brandon King

  SQL Server 2008 provides the ability to script data as Insert statements using the Generate Scripts option in Management Studio. Is it possible to access the same functionality from within a SSIS package? Here's what I'm trying to accomplish... I have a scheduled job that nightly scripts out all the schema and data for a SQL Server 2008 database and then uses the script to create a "mirror copy" SQLCE 3.5 database. I've been using Narayana Vyas Kondreddi's sp_generate_inserts stored procedure to accomplish this, but it has problems with some datatypes and greater-than-4K columns (holdovers from SQL Server 2000 days). The Script Data function looks like it could solve my problems, if only I could automate it. Any suggestions?

• Modify Emdeded String in C# compiled exe

  - by nitefrog

  I have an issue where I need to be able to have a compiled exe ( .net 3.5 c# ) that I will make copies of to distribute that will need to change a key for example before the exe is sent out. I cannot compile each time a new exe is needed. This is a thin client that will be used as part of a registration process. Is it possible to add a entry to a resource file with a blank value then when a request comes in have another application grab the blank default thin client, copy it, populate the blank value with the data needed. If yes how? If no do you have any ideas? I have been scratching my head for a few days now and the limitation as due to the boundaries I am required to work in. The other idea I has was to inject the value into a method, which I have no idea how I would even attempt that. Thanks.

• when does a software become "proprietary" ?

  - by wefwgeweg

  say a company is using Open source libraries, or programs, and packaging it into a proprietary solution. or perhaps, the engineers have copy pasted certain section of those open source libraries and have compiled it now, into a very useful "proprietary" software suite. what legal troubles will this company face if any ? are you allowed to do this ? i mean the customer doesn't see the source codes, only runs the binary files on their computer. for example, i find an excellent NLP library in python, and decide to use it in my program that i am selling for $4000 USD (i write like 10 lines of code and let the library do the work). could i get into trouble ? would i need to write the NLP library myself from scratch to be considered "proprietary" ? danke

• Can documents indexed with Solr on JDK6 be retrieved using only lucene api on JDK1.4?

  - by huynhjl

  My runtime environment is still on JDK1.4 but I like the Solr features related to how documents are ingested and indexed. Would I be able to index my documents using Solr offline on a recent version of the JDK, copy the index over and use it in my runtime environment with an older version of the JDK? Version wise, Solr 1.4.0 uses Apache Lucene 2.9.1 which is JDK1.4 compatible. (but Solr itself requires JDK5). Assuming what I'm trying to do is even possible, what features would I lose if I search Solr indices only with the Lucene API?

• Developing Qt applications in Unix systems using Qt Creator

  - by Jake Petroules

  I'm developing a Qt application in Linux using Qt Creator (2.1 RC). I've created 2 projects, and used the wizard to add the library project to the application project. However when I run it, I receive the error: /home/jakepetroules/silverlock/silverlock-build-desktop/desktop/silverlock: error while loading shared libraries: libsilverlocklib.so.1: cannot open shared object file: No such file or directory Is there some qmake variable I can set so that Qt Creator will set up the environment properly to run? It's quite annoying to have to copy all the files to another directory with a launcher script just to be able to test the build. On Windows it works perfectly - Qt Creator automatically adds the directories containing the DLLs to the PATH when it runs your application (where running it from Explorer would say DLL not found). Mac OS X is even worse, having to run install_name_tool on everything... So how can I set up my qmake files so everything works right from the run button in Qt Creator? Kind of hard to debug without this ability, too.

• Comparing 2 mysql tables and updating only records that have changed

  - by Roland

  I have the following. Two mysql tables. I want to copy info that has changed from table a to b. For example if row 1 column 2 has changed in table a I want to only update that column in table b. Table b is not the same as a but has same columns that also exist in a. The other solution I have is to just clear table b and replace it with the contents from table a, the problem with this could be that the script will take longer to execute, since there are more than 10000 records. Any advise for which method would work the best will be highly appreciated

• Python: Remove items from a list while iterating in Python

  - by xApple

  My problem is simple: I have a long list of elements that I want to iterate through and check every element against a condition. Depending on the outcome of the condition I would like to delete the current element of the list, and continue iterating over it as usual. I have read a few other threads on this matter. Two solutions seam to be proposed. Either make a dictionary out of the list (which implies making a copy of all the data that is already filling all the RAM in my case). Either walk the list in reverse (which breaks the concept of the alogrithm I want to implement). Is there any better or more elegant way than this to do it ? def walk_list(list_of_g): g_index = 0 while g_index < len(list_of_g): g_current = list_of_g[g_index] if subtle_condition(g_current): list_of_g.pop(g_index) else: g_index = g_index + 1

• Typed Arrays in Gecko 2: Float32Array concatenation and expansion.

  - by janesconference

  Hi all, I'm a bit confused with Javascript Typed Arrays. What I have several *Float32Array*s, that have no concat method. I'd like to concatenate them all inside another Float32Array, but: as I said before, there is no concatenation method if I try to write past the array length, the array is not expanded (aka this won't work - please note that event.frameBuffer and buffer are both Float32Array and that I don't know what the final length of my buffer will be): var length_now = buffer.length; for (var i = 0; i < event.frameBuffer.length; i += 1) { buffer [length_now + i] = event.frameBuffer[i]; } The only solution I found is to copy the Float32Array in a regular array, that's definitely not what I want. How would you do, stackoverflowers?

• How should I move my code from dev to production?

  - by Teddy

  I have created a PHP web-application. I have 3 environments: DEV, TEST, PROD. What's a good tool / business practice for me to move my PHP web-application code from DEV to TEST to the PROD environment? Realizing that my TEST environment still only connects to my TEST database; whereas, I need to PROD environment to connect to my PROD database. So the code is mostly the same, except that I need to change my TEST code once moved into PROD to connect to the PROD database and not TEST database. I've heard of people taking down Apache in such away that it doesn't allow new connections and once all the existing connections are idle it simply brings down the web server. Then people manually copy the code and then manually update the config files of the PHP application to also point to the PROD instance. That seems terribly dangerous. Does a best practice exists?
