• psqlODBC won't load after installing MS SQL ODBC driver on RHEL 6

  - by Kapil Vyas

  I had the PostgreSQL drivers working on my RHEL 6. But after I installed Microsoft® SQL Server® ODBC Driver 1.0 for Linux I can no longer connect to PosgreSQL data sources. I can connect to SQL Server data sources fine. When I had this same issue a week ago I uninstalled MS SQL Server ODBC driver from Linux and it fixed the issue. I had to copy the psqlodbcw.so files from another machine to replenish the files. I don't want to do the same this time. I want both drivers to work on Linux. This time around the setup files got deleted: /usr/lib64/libodbcpsqlS.so. Replenishing it did not fix the issue. I kept getting the following error in spite of the file being present with rwx permisions: [root@localhost lib64]# isql -v STUDENT dsname pwd12345 [01000][unixODBC][Driver Manager]Can't open lib '/usr/lib64/psqlodbc.so' : file not found [ISQL]ERROR: Could not SQLConnect [root@localhost lib64]# Here is a printout of the file permissions: [root@localhost lib64]# ls -al p*.so lrwxrwxrwx. 1 root root 12 Dec 7 09:15 psqlodbc.so -> psqlodbcw.so -rwxr-xr-x. 1 root root 519496 Dec 7 09:35 psqlodbcw.so and my odbcinst.ini file looks as follows: [PostgreSQL] Description=ODBC for PostgreSQL Driver=/usr/lib/psqlodbc.so Driver64=/usr/lib64/psqlodbc.so Setup=/usr/lib/libodbcpsqlS.so Setup64=/usr/lib64/libodbcpsqlS.so FileUsage=1 UsageCount=4 I also referred to this link: http://mailman.unixodbc.org/pipermail/unixodbc-support/2010-September.txt

• how to synchronize database table and directory with php

  - by twmulloy

  hello, I have a directory with files and a database table with what should be the same files. I would like to be able to synchronize the database table with the directory. What would be the most efficient way to do this? or would I realistically only be able to do this in a brute manner? Here's my approach: 1. retrieve all of the files in the directory as array 2. retrieve all of the filenames in the database table as array 3. loop through the file values in the directory array and use in_array() on the database table array to verify the filename is in that array, and if not then start building an array to insert the missing filenames. run db query to add each missing file row to database table 4. loop through directory array and use in_array() on the directory array and anything not found in the directory array will just be deleted from the table. Is there a better way to go about this? or something better for this in php than in_array()?

• Request size limitation when using MultipartHttpServletRequest of Spring 3.0

  - by Spiderman

  I'd like to know what is the size limitation if I upload list of files in one client's form submition using HTTP multipart content type. On the server side I am using Spring's MultipartHttpServletRequest to handle the request. mM questions: Is there should be different file size limitation and total request size limitation or file size is the only limitation and the request is capable of uploading 100s of files as lonng as they are not too large. Doest the Spring request wrapper read the complete request and store it in the JAVA heap memory or it store temporaray files of it to be able to use big quota. Is the use of reading the httpservlet request in streaming would change the size limitation than using complete http request read at-once by the application server. What is the bottleneck of this process - Java heap size, the quota of the filesystem on which my web-server runs, the maximum allowed BLOB size that the DataBase in which I am gonna save the file alows? or Spring internal limitations? Related threads that still don't have exact answer to this: does-spring-framework-support-streaming-mode-in-mutlipart-requests is-there-a-way-to-get-raw-http-request-stream-from-java-servlet-handler how-to- drop-body-of-a-request-after-checking-headers-in-servlet apache-commons-fileupload-throws-malformedstreamexception

• How do I implement configurations and settings?

  - by Malvolio

  I'm writing a system that is deployed in several places and each site needs its own configurations and settings. A "configuration" is a named value that is necessary to a particular site (e.g., the database URL, S3 bucket name); every configuration is necessary, there is not usually a default, and it's typically string-valued. A setting is a named value but it just tweaks the behavior of the system; it's often numeric or Boolean, and there's usually some default. So far, I've been using property files or thing like them, but it's a terrible solution. Several times, a developer has added a requirement for a configuration but not added the value to file for the live configuration, so the new release passed all the tests, then failed when released to live. Better, of course, for every file to be compiled — so if there's a missing configuration, or one of the wrong type, it won't get past the compiler — and inject the site-specific class into the build for each site. As a bones, a Scala file can easy model more complex values, especially lists, but also maps and tuples. The downside is, the files are sometimes maintained by people who aren't developers, so it has to be pretty self-explanatory, which was the advantage of property files. (Someone explain XML configurations to me: all the complexity of a compilable file but the run-time risk of a property file.) What I'm looking for is an easy pattern for defining a group required names and allowable values. Any suggestions?

  How can I solve "cannot find interface declaration 'someEnumeration', superclass of 'interfaceName'" error? What steps will reproduce the problem? Compiling Wsdl2ObjC Targeting groupwise.wsdl file Fixing non-valid file names of output csource code like ".h" + ".m" and objects inside source files Moving up one of the @interface BEFORE it was used futher in code! What is the expected output? Something working What do you see instead? 33 errors. "Inherited" from only 3 similar Inheritances of a typedef enum object by a class. All errors are typical: typedef enum types_StatusTrackingOptions { types_StatusTrackingOptions_none = 0, types_StatusTrackingOptions_None, types_StatusTrackingOptions_Delivered, types_StatusTrackingOptions_DeliveredAndOpened, types_StatusTrackingOptions_All, } types_StatusTrackingOptions; types_StatusTrackingOptions types_StatusTrackingOptions_enumFromString(NSString *string); NSString * types_StatusTrackingOptions_stringFromEnum(types_StatusTrackingOptions enumValue); @interface types_StatusTracking : types_StatusTrackingOptions { ... and here I'm having error "cannot find interface declaration for 'types_StatusTrackingOptions', superclass of 'types_StatusTracking'".

• Pass a Message From Thread to Update UI

  - by Jay Dee

  Ive created a new thread for a file browser. The thread reads the contents of a directory. What I want to do is update the UI thread to draw a graphical representation of the files and folders. I know I can't update the UI from within a new thread so what I want to do is: whilst the file scanning thread iterates through a directories files and folders pass a file path string back to the UI thread. The handler in the UI thread then draws the graphical representation of the file passed back. public class New_Project extends Activity implements Runnable { private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { Log.d("New Thread","Proccess Complete."); Intent intent = new Intent(); setResult(RESULT_OK, intent); finish(); } }; public void getFiles(){ //if (!XMLEFunctions.canReadExternal(this)) return; pd = ProgressDialog.show(this, "Reading Directory.", "Please Wait...", true, false); Log.d("New Thread","Called"); Thread thread = new Thread(this); thread.start(); } public void run() { Log.d("New Thread","Reading Files"); getFiles(); handler.sendEmptyMessage(0); } public void getFiles() { for (int i=0;i<=allFiles.length-1;i++){ //I WANT TO PASS THE FILE PATH BACK TU A HANDLER IN THE UI //SO IT CAN BE DRAWN. **passFilePathBackToBeDrawn(allFiles[i].toString());** } } }

• Any diff/merge tool that provides a report (metrics) of conflicts?

  - by cad

  CONTEXT: I am preparing a big C# merge using visual studio 2008 and TFS. I need to create a report with the files and the number of collisions (total changes and conflicts) for each file (and in total of course) PROBLEM: I cannot do it for two reasons (first one is solved): 1- Using TFS merge I can have access to the file comparison but I cannot export the list of conflicting files... I can only try to resolve the conflicts. (I have solved problem 1 using beyond compare. It allows me to export the file list) 2- Using TFS merge I can only access manually for each file to get the number of conflicts... but I have more than 800 files (and probably will have to repeat it in the close future so is not an option doing it manually) There are dozens of file comparison tools (http://en.wikipedia.org/wiki/Comparison_of_file_comparison_tools ) but I am not sure which one could (if any) give me these metrics. I have also read several forums and questions here but are more general questions (which diff tool is better) and I am looking for a very specific report. So my questions are: Is Visual Studio 2010 (using still TFS2008) capable of doing such reports/exportation? Is there any tool that provide this kind of metrics (Now I am trying Beyond Compare)

• ASP.NET Web Optimization - confusion about loading order

  - by Ciel

  Using the ASP.NET Web Optimization Framework, I am attempting to load some javascript files up. It works fine, except I am running into a peculiar situation with either the loading order, the loading speed, or its execution. I cannot figure out which. Basically, I am using ace code editor for javascript, and I also want to include its autocompletion package. This requires two files. /ace.js /ext-language_tools.js This isn't an issue, if I load both of these files the normal way (with <script> tags) it works fine. But when I try to use the web optimization bundles, it seems as if something goes wrong. Trying this out... bundles.Add(new ScriptBundle("~/bundles/js") { .Include("~/js/ace.js") .Include("~/js/ext-language_tools.js") }); and then in the view .. @Scripts.Render("~/bundles/js") I get the error ace is not defined This means that the ace.js file hasn't run, or hasn't loaded. Because if I break it apart into two bundles, it starts working. bundles.Add(new ScriptBundle("~/bundles/js") { .Include("~/js/ace.js") }); bundles.Add(new ScriptBundle("~/bundles/js/language_tools") { .Include("~/js/ext-language_tools.js") }); Can anyone explain why this would behave in this fashion?

• rails not recognizing project

• What happens to existing workspaces after upgrading to TFS 2010

  - by e-mre

  Hi, I was looking for some insight about what happens to existing workspaces and files that are already checked-out on people, after an upgrade to TFS2010. Surprisingly enough I can not find any satisfactory information on this. (I am talking about upgrading on new hardware by the way. Fresh TFS instance, upgraded databases) I've checked TFS Installation guide, I searched through the web, all I could find is upgrade scenarios for the server side. Nobody even mentions what happens to source control clients. I've created a virtual machine to test the upgrade process, The upgrade was successful and all my files and workspaces exist in the new server too. The problem is: The new TFS installation has a new instanceID. When I redirected on the clients to the new server, the client seemed unable to match files and file states in the workspace with the ones on the new server. This makes me wonder if it will be possible to keep working after the production upgrade. As I mentioned above I can not find anything on this, it would be great if anyone could point me to some paper or blog post about this. Thanks in advance...

• Regular Expression to replace a pattern at runtime(C#3.0)

  - by deepak.kumar.goyal

  I have a requirement. I have some files in a folder among which some file names looks like say **EUDataFiles20100503.txt, MigrateFiles20101006.txt.** Basically these are the files that I need to work upon. Now I have a config file where it is mentioned as the file pattern type as EUDataFilesYYYYMMDD, MigrateFilesYYYYMMDD. Basically the idea is that, the user can configure the file pattern and based on the pattern mentioned, I need to search for those files that are present in the folder. i.e. at runtime the YYYYMMDD will get replaced by the Year Month and Date Values. It does not matter what dates will be there(but not with time stamp ; only dates)). And the EUDataFiles or MigrateFiles names will be there.(they are fixed) i.e. If the folder has a file name as EUDataFile20100504.txt(i.e. Year 2010, Month 05, Day 04) , I should ignore this file as it is not EUDataFiles20100504.txt (kindly note that the name is plural - File(s) and not file for which the system will ignore the file). Similarly, if the Pattern given as EUDataFilesYYYYMMDD and if the file present is of type EUDataFilesYYYYDDMM then also the system should ignore. How can I solve this problem? Is it doable using regular expression(Replacing the pattern at runtime)? If so can anyone be good enough in helping me out? I am using C#3.0 and dotnet framework 3.5. Thanks

• getting CS1502 compiler error on dev environment but not production.

  - by nw

  When I try to run my ASP.NET app from my development environment I get the following error message: Compiler Error Message: CS1502: The best overloaded method match for 'mmars.Printing.printFunctions.SetPrintSummaryProperties(mmars.contextInfo, ref mmars.Printing.printObjSummary)' has some invalid arguments. When I publish and run on our production server I don't get this error. It seems to compile fine when I build from the build menu (in fact if I change the second argument of the bolded function call below, i get a compiler error in visual studio), but now i've suddenly started getting this error message at runtime. So another question I have in addition to getting rid of the error is why is the .NET development server even trying to do JIT compilation on my project if it is already compiled into a DLL? Printing.printObjSummary myPrintObj = new Printing.printObjSummary(); Printing.printFunctions.SetPrintSummaryProperties(ci, ref myPrintObj); printObjects.Add(myPrintObj); This seems to have just suddenly appeared from nowhere today and it's extremely frustrating. Also, though there are no warnings at compile-time, when I get redirected to the page with that first compilation error there are many warnings like the following: Warning: CS0436: The type 'mmars.MMARSSummaryDataItem' in 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\3dad423c\40569048\App_Code.b0rgpkzr.4.cs' conflicts with the imported type 'mmars.MMARSSummaryDataItem' in 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\3dad423c\40569048\assembly\dl3\7179c19a\345f948c_ece7ca01\mmars.DLL'. Using the type defined in 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\3dad423c\40569048\App_Code.b0rgpkzr.4.cs'. What's the deal with that? Is the webserver complaining about name conflicts in the source file and dll resulting from the source file?

• Is XSLT worth investing time in and are there any actual alternatives?

  - by Keeno

  I realize this has been a few other questions on this topic, and people are saying use your language of choice to manipulate the XML etc etc however, not quite fit my question exactly. Firstly, the scope of the project: We want to develop platform independent e-learning, currently, its a bunch of HTML pages but as they grow and develop they become hard to maintain. The idea: Generate up an XML file + Schema, then produce some XSLT files that process the XML into the eLearning modiles. XML to HTML via XSLT. Why: We would like the flexibilty to be able to easy reformat the content (I realize CSS is a viable alternative here) If we decide to alter the pages layout or functionality in anyway, im guessing altering the "shared" XSLT files would be easier than updating the HTML files. So far, we have about 30 modules, with up to 10-30 pages each Depending on some "parameters" we could output drastically different page layouts/structures, above and beyond what CSS can do Now, all this has to be platform independent, and to be able to run "offline" i.e. without a server powering the HTML Negatives I've read so far for XSLT: Overhead? Not exactly sure why...is it the compute power need to convert to HTML? Difficult to learn Better alternatives Now, what I would like to know exactly is: are there actually any viable alternatives for this "offline"? Am I going about it in the correct manner, do you guys have any advice or alternatives. Thanks!

• How can I embed images within my application and use them in HTML control?

  - by Atara

  Is there any way I can embed the images within my exe (as resource?) and use it in generated HTML ? Here are the requirements: A. I want to show dynamic HTML content (e.g. using webBrowser control, VS 2008, VB .Net, winForm desktop application) B. I want to generate the HTML on-the-fly using XML and XSL (file1.xml or file2.xml transformed by my.xsl) C. The HTML may contain IMG tags (file1.gif and or file2.gif according to the xml+xsl transformation) and here comes the complicated one: D. All these files (file1.xml, file2.xml, my.xsl, file1.gif, file2.gif) should be embedded in one exe file. I guess the XML and XSL can be embedded resources, and I can read them as stream, but what ways do I have to reference the image within the HTML ? <IMG src="???" /> I do not want to use absolute path and external files. If the image files are resources, can I use relative path? Relative to what? (I can use BASE tag, and then what?) Can I use stream as in email messages? If so, where can I find the format I need to use? http://www.websiteoptimization.com/speed/tweak/inline-images/ are browser dependent. What is the browser used by webBrowser control? IE? what version? Does it matter if I use GIF or JPG or BMP (or any other image format) for the images? Does it matter if I use mshtml library and not the regular webBrowser control? (currently I use http://www.itwriting.com/htmleditor/index.php ) Does it matter if I upgrade to VS 2010 ? Thanks, Atara

• Load PEM encoded private RSA key in Crypto++

  - by 01100110

  Often times, user will have PEM encoded RSA private keys. Crypto++ requires that these keys be in DER format to load. I've been asking people to manually convert their PEM files to DER beforehand using openssl like this: openssl pkcs8 -in in_file.pem -out out_file.der -topk8 -nocrypt -outform der That works fine, but some people don't understand how to do that nor do they want to. So I would like to convert PEM files to DER files automatically within the program. Is it as simple as striping the "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" from the PEM or is some other transformation required as well? I've been told that between those markers that it's just b64 encoded DER. Here's some code that demonstrates the issue: // load the private key CryptoPP::RSA::PrivateKey PK; CryptoPP::ByteQueue bytes; try { CryptoPP::FileSource File( rsa.c_str(), true, new CryptoPP::Base64Decoder() ); File.TransferTo( bytes ); bytes.MessageEnd(); // This line Causes BERDecodeError when a PEM encoded file is used PK.Load( bytes ); } catch ( CryptoPP::BERDecodeErr ) { // Convert PEM to DER and try to load the key again } I'd like to avoid making system calls to openssl and do the transformation entirely in Crypto++ so that users can provide either format and things "just work". Thanks for any advice.

• AppDomain.Unload doesn't release the assembly I loaded up with Reflection

  Hi All, I am struggling with an issue while loading an assembly up in a temporary AppDomain to read its GetUsedReferences property. Once I do that, I call AppDomain.Unload(tempDomain) and then I try to clean up my mess by deleting the files. That fails because the file is locked. I Unloaded the temporary domain though! Any thoughts or suggestions would be greately appreciated. Here is some of my code: //I already have btyes for the .dll and the .pdb from the actual files AppDomainSetup domainSetup = new AppDomainSetup(); domainSetup.ApplicationBase = Environment.CurrentDirectory; domainSetup.ShadowCopyFiles = "true"; domainSetup.CachePath = Environment.CurrentDirectory; AppDomain tempAppDomain = AppDomain.CreateDomain("TempAppDomain", AppDomain.CurrentDomain.Evidence, domainSetup); //Load up the temp assembly and do stuff Assembly projectAssembly = tempAppDomain.Load(assemblyFileBuffer, symbolsFileBuffer); //Then I'm trying to clean up AppDomain.Unload(tempAppDomain); tempAppDomain = null; File.Delete(tempAssemblyFile); //I even try to force GC File.Delete(tempSymbolsFile); Anyway, the Deletes fail because the files are locked still. Shouldn't they be released because I Unloaded the temporary AppDomain?!?!?! Thanks in advance, Dan

• how to monitor the program code execution? (file creation and modification by code lines etc)

  - by infant programmer

  My program is about triggering XSL transformation, Its fact that this code for carrying out the transformation, creates some dll and tmp files and deletes them pretty soon after the transformation is completed. It is almost untraceable for me to monitor the creation and deletion of files manually, so I want to include some chunk of codelines to display "which codeline has created/modified which tmp and dll files" in console window.

• import csv file/excel into sql database asp.net

  - by kiev

  Hi everyone! I am starting a project with asp.net visual studio 2008 / SQL 2000 (2005 in future) using c#. The tricky part for me is that the existing DB schema changes often and the import files columns will all have to me matched up with the existing db schema since they may not be one to one match on column names. (There is a lookup table that provides the tables schema with column names I will use) I am exploring different ways to approach this, and need some expert advice. Is there any existing controls or frameworks that I can leverage to do any of this? So far I explored FileUpload .NET control, as well as some 3rd party upload controls to accomplish the upload such as SlickUpload but the files uploaded should be < 500mb Next part is reading of my csv /excel and parsing it for display to the user so they can match it with our db schema. I saw CSVReader and others but for excel its more difficult since I will need to support different versions. Essentially The user performing this import will insert and/or update several tables from this import file. There are other more advance requirements like record matching but and preview of the import records, but I wish to get through understanding how to do this first. Update: I ended up using csvReader with LumenWorks.Framework for uploading the csv files.

• How can I accelerate the generation of the an MD5 Checksum within vb.net?

  - by Richard

  I'm working with some very large files residing on P2 (Panasonic) cards. Part of the process we employ is to first generate a checksum of the file we are going to copy, then copy the file, then run a checksum on the file to confirm that it copied OK. The problem is, is that files are large (70 GB+) and take a long time to complete. It's an issue since we will eventually be dealing with thousands of these files. I would like to find a faster way to generate the checksum other than using the System.Security.Cryptography.MD5CryptoServiceProvider I don't care if this means using a specialized hardware card, provided it works and is not to ungodly expensive. I would prefer to have a method of encoding that provided some feedback as to how far the process has gone along so I can display it like I do now. The application is written in vb.net. I would prefer to be able to use it as component, library, reference within my application, but I'm willing to call an outside application if there is enough improvement in the speed of generating the checksum. Needless to say, the checksum must be consistent and correct. :-) Thank you in advance for your time and efforts, Richard

• Reasonably faster way to traverse a directory tree in Python?

  - by Sridhar Ratnakumar

  Assuming that the given directory tree is of reasonable size: say an open source project like Twisted or Python, what is the fastest way to traverse and iterate over the absolute path of all files/directories inside that directory? I want to do this from within Python (subprocess is allowed). os.path.walk is slow. So I tried ls -lR and tree -fi. For a project with about 8337 files (including tmp, pyc, test, .svn files): $ time tree -fi > /dev/null real 0m0.170s user 0m0.044s sys 0m0.123s $ time ls -lR > /dev/null real 0m0.292s user 0m0.138s sys 0m0.152s $ time find . > /dev/null real 0m0.074s user 0m0.017s sys 0m0.056s $ tree appears to be faster than ls -lR (though ls -R is faster than tree, but it does not give full paths). find is the fastest. Can anyone think of a faster and/or better approach? On Windows, I may simply ship a 32-bit binary tree.exe or ls.exe if necessary. Update 1: Added find

• Fixing merge conflicts?

  - by user291701

  I have two remote branches, "grape" and "master". I'm currently on "grape". Now I switch to "master": git checkout master Now I want to pull all changes from "grape" into "master" - is this the way to do it?: git merge origin grape It's my understanding that git will then pull all the current state of the remote branch "grape" into my local copy of "master". It will try to auto-merge for me. If there are conflicts, the files in conflict will have some conflict text actually injected into the file. I then have to go into those files, and delete the chunk I don't want (essentially telling git how to merge these files). For each file in conflict, do I add and commit the changes again?: git add problemfile1.txt git commit -m "Fixed merge conflict." git add problemfile2.txt git commit -m "Fixed another merge conflict." ... after I've fixed all the merge conflicts like above, do I just push to "master" again to finish up the process?: git push origin master or is there something else we need to do when we get into this conflict state? Thank you
