  • Problem with deployment of windows application using setup wizard.

    - by Mike
    I have some xml files, which are used in my application. They are stored in the same folder with application , in subfolder DATA: "C:\MyProject\DATA\". To get the DATA folder path i use this code : static public string GetDataFolderPath() { string s = System.IO.Directory.GetCurrentDirectory().Replace(@"\bin\Debug", ""); int i = s.LastIndexOf(@"\"); s = s.Substring(0, i); i = s.LastIndexOf(@"\"); s= s.Substring(0, i); return s + @"\Data\"; } So when i want to deploy my application, i create a setup project, and add the DATA folder to Application folder. But after i install the program f.e. "C:\Project"(DATA folder- "C:\Project\DATA" i got the error: "folder C:\DATA is not found". What i need to change to make things working after deployment. Why it looks for the DATA folder on 1 level higher?

  • SQL Profiles showing high activity

    - by Wong Chi
    I am running my application locally -- ie. No external traffic and very low number of queries, fully under my control. I see tons of 'Audit Login' and 'Audit Logout' events. What are these and where are they actually stored (ie. Where is this audit log)? Are these a hint of a problem with connections, because I have only a simple connection string within my app and thought that connections would remain active throughout the operation of my app (ie. a single login at launch, and then a single logout when terminating).

  • PHP and MySQL SELECT problem.

    - by R.I.P.coalMINERS
    Trying to check if a name is already stored in the database from the login user. The name is a set of dynamic arrays entered by the user threw a set of dynamic form fields added by the user. Can some show me how to check and see if the name is already entered by the login user? I know my code can't be right. Thanks! MySQL code. SELECT * FROM names WHERE name = '" . $_POST['name'] . "' AND userID = '$userID' Here is the MySQL table. CREATE TABLE names ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, userID INT NOT NULL, name VARCHAR(255) NOT NULL, meaning VARCHAR(255) NOT NULL, PRIMARY KEY (id) );

  • Yes another ON DUPLICATE KEY UPDATE query

    - by Andy Gee
    I've been reading all the questions on here but I still don't get it I have two identical tables of considerable size. I would like to update table packages_sorted with data from packages_sorted_temp without destroying the existing data on packages_sorted Table packages_sorted_temp contains data on only 2 columns db_id and quality_rank Table packages_sorted contains data on all 35 columns but quality_rank is 0 The primary key on each table is db_id and this is what I want to trigger the ON DUPLICATE KEY UPDATE with. In essence how do I merge these two tables by and change packages_sorted.quality_rank of 0 to the quality_rank stored in packages_sorted_temp under the same primary key Here's what's not working INSERT INTO `packages_sorted` ( `db_id` , `quality_rank` ) SELECT `db_id` , `quality_rank` FROM `packages_sorted_temp` ON DUPLICATE KEY UPDATE `packages_sorted`.`db_id` = `packages_sorted`.`db_id`

  • Is it possible to use an incremental value within a variable name whilst declaring it within a loop?

    - by Jack
    Hi, I'm creating function which will read different XML files each time that will contain different amounts of the same nodes. I have already created a loop which stores the ID of each node into an array, and now I want to create variables for each array member which store attributes of the node with each ID. Because the number of nodes will be different for every XML document my function reads, I cannot manually assign variables for the attributes of each node ID not knowing how many to assign, so I have created a loop which runs specific to the number of items I have stored in the array. Inside this loop I was hoping to have something like: for (i=0; i<array.length; i++) { var ID + i + width = exampleheight var ID + i + height = exampleheight } I know this doesn't work, but was trying to outline what I am looking to find out. Is it possible to use some kind of variable or random number when declaring a variable?

  • deleting a large number of rows from a table

    - by Azeem
    We have a requirement to delete rows in the order of millions from multiple tables as a batch job (note that we are not deleting all the rows, we are deleting based on a timestamp stored in an indexed column). Obviously a normal DELETE takes forever (because of logging, referential constraint checking etc.). I know in the LUW world, we have ALTER TABLE NOT LOGGED INITIALLY but I can't seem to find the an equivalent SQL statement for DB2 v8 z/OS. Any one has any ideas on how to do this really fast? Also, any ideas on how to avoid the referential checks when deleting the rows? Please let me know.

  • how to get audio frequency data from a wave file?

    - by potlee
    I want to build a speech recognition engine in ruby. I know i'll never get there, doing it just for fun. I need to get data for the frequencies of the sound stored in a wav file to compare with data i already have of different sounds that i want to recognize. I will write the code in ruby but i dont think there are any libraries for this written in ruby, they would be too slow if there were any anyway. The good thing about ruby is I'll be able to use libraries for .net via IronRuby or Java via Jruby. How can i get the frequency data?

  • How to detect image orientation (text)

    - by Maciej
    My program is working with fax documents stored as separate bitmaps I wonder if there is a way to detect automatically page orientation (vertical or horizontal) to show image preview for user in right order (meant rotate if neccesary) Any advices much appreciated! EDIT: Clarification: When Faxmachine receives multi-page document it saves each page as separate TIFF file. My app has built-in viewer displaying those files. All files are scaled to A4 format and saved in TIFF (so there is no change to detect orientation by height/width parameters) My viewer displays images in portrait mode by default What I'd like to do is automagically detect situation when org document was printed in landscape mode (eg wide Excel tables) then I'd like to show rotated preview for end user to speed up preview process Obviously there are 4 possible fax orientation portrait / landscape x 2 kind of rotations. I'm even interested simplified solution detecting when org doc was landscape or portrait (I've noticed most of landscape docs needs to be rotated clockwise)

  • Perl - Reading .txt files line-by-line and using compare function (printing non-matches only once)

    - by Kurt W
    I am really struggling and have spent about two full days on this banging my head against receiving the same result every time I run this perl script. I have a Perl script that connects to a vendor tool and stores data for ~26 different elements within @data. There is a foreach loop for @data that breaks the 26 elements into $e-{'element1'), $e-{'element2'), $e-{'element3'), $e-{'element4'), etc. etc. etc. I am also reading from the .txt files within a directory (line-by-line) and comparing the server names that exist within the text files with what exists in $e-{'element4'}. The Problem: Matches are working perfectly and only printing one line for each of the 26 elements when there is a match, however non-matches are producing one line for every entry within the .txt files (37 in all). So if there are 100 entries (each entry having 26 elements) stored within @data, then there are 100 x 37 entries being printed. So for every non-match in the: if ($e-{'element4'} eq '6' && $_ =~ /$e-{element7}/i) statement below, I am receiving a print out saying that there is not a match. 37 entries for the same identical 26 elements (because there are 37 total entries in all of the .txt files). The Goal: I need to print out only 1 line for each unique entry (a unique entry being $e-{element1} thru $e-{element26}). It is already printing one 1 line for matches, but it is printing out 37 entries when there is not a match. I need to treat matches and non-matches differently. Code: foreach my $e (@data) { # Open the .txt files stored within $basePath and use for comparison: opendir(DIRC, $basePath . "/") || die ("cannot open directory"); my @files=(readdir(DIRC)); my @MPG_assets = grep(/(.*?).txt/, @files); # Loop through each system name found and compare it with the data in SC for a match: foreach(@MPG_assets) { $filename = $_; open (MPGFILES, $basePath . "/" . $filename) || die "canot open the file"; while(<MPGFILES>) { if ($e->{'element4'} eq '6' && $_ =~ /$e->{'element7'}/i) { ## THIS SECTION WORKS PERFECTLY AND ONLY PRINTS MATCHES WHERE $_ ## (which contains the servernames (1 per line) in the .txt files) ## EQUALS $e->{'element7'}. print $e->{'element1'} . "\n"; print $e->{'element2'} . "\n"; print $e->{'element3'} . "\n"; print $e->{'element4'} . "\n"; print $e->{'element5'} . "\n"; # ... print $e->{'element26'} . "\n"; } else { ## **THIS SECTION DOES NOT WORK**. FOR EVERY NON-MATCH, THERE IS A ## LINE PRINTED WITH 26 IDENTICAL ELEMENTS BECAUSE ITS LOOPING THRU ## THE 37 LINES IN THE *.TXT FILES. print $e->{'element1'} . "\n"; print $e->{'element2'} . "\n"; print $e->{'element3'} . "\n"; print $e->{'element4'} . "\n"; print $e->{'element5'} . "\n"; # ... print $e->{'element26'} . "\n"; } # End of 'if ($e->{'element4'} eq..' statement } # End of while loop } # End of 'foreach(@MPG_assets)' } # End of 'foreach my $e (@data)' I think I need something to identical unique elements and define what fields make up a unique element but honestly I have tried everything I know. If you would be so kind to provide actual code fixes, that would be wonderful because I am headed to production with this script quite soon. Also. I am looking for code (ideally) that is very human-readable because I will need to document it so others can understand. Please let me know if you need additional information.

  • History tables pros, cons and gotchas - using triggers, sproc or at application level.

    - by Nathan W
    I am currently playing around with the idea of having history tables for some of my tables in my database. Basically I have the main table and a copy of that table with a modified date and an action column to store what action was preformed eg Update,Delete and Insert. So far I can think of three different places that you can do the history table work. Triggers on the main table for update, insert and delete. (Database) Stored procedures. (Database) Application layer. (Application) My main question is, what are the pros, cons and gotchas of doing the work in each of these layers. One advantage I can think of by using the triggers way is that integrity is always maintained no matter what program is implmentated on top of the database.

  • Python - Is it possible to get the name of the chained function?

    - by user1326876
    I'm working on a class that basically allows for method chaining, for setting some attrbutes for different dictionaries stored. The syntax is as follows: d = Test() d.connect().setAttrbutes(Message=Blah, Circle=True, Key=True) But there can also be other instances, so, for example: d = Test() d.initialise().setAttrbutes(Message=Blah) Now I believe that I can overwrite the "setattrbutes" function; I just don't want to create a function for each of the dictionary. Instead I want to capture the name of the previous chained function. So in the example above I would then be given "connect" and "initialise" so I know which dictionary to store these inside. I hope this makes sense. Any ideas would be greatly appreciated :)

  • Storing PDFs in MS Access Database using Forms

    - by Matthew Jones
    I need to store PDF files in an Access database on a shared drive using a form. I figured out how to do this in tables (using the OLE Object field, then just drag-and-drop) but I would like to do this on a Form that has a Save button. Clicking the save button would store the file (not just a link) in the database. Any ideas on how to do this? EDIT: I am using Access 2003, and the DB will be stored on a share drive, so I'm not sure linking to the files will solve the problem.

  • A better understanding of the relations beetween database tables

    - by Nistor Alexandru
    Hi I am trying to get a better understanding of relational databases and there is something that I keep bumping into and don't understand.Let's take this two tables: In this case Login.ID is the primary key with auto_increment set and Profile.ID_LOGIN is the Foreign KEY.When a user is created and it's username and password is stored in the login database does the ID coresponding to the curesnt username and password get automaticly added into ID_LOGIN or do I have to create an SQL statement to do this? If I have to create a SQL statement how should I aproach adding the ID_LOGIN to make sure I am adding it corectly?

  • Architecture for analysing search result impressions/clicks to improve future searches

    - by Hais
    We have a large database of items (10m+) stored in MySQL and intend to implement search on metadata on these items, taking advantage of something like Sphinx. The dataset will be changing slightly on a daily basis so Sphinx will be re-indexing daily. However we want the algorithm to self-learn and improve search results by analysing impression and click data so that we provide better results for our customers on that search term, and possibly other similar search terms too. I've been reading up on Hadoop and it seems like it has the potential to crunch all this data, although I'm still unsure how to approach it. Amazon has tutorials for compiling impression vs click data using MapReduce but I can't see how to get this data in a useable format. My idea is that when a search term comes in I query Sphinx to get all the matching items from the dataset, then query the analytics (compiled on an hourly basis or similar) so that we know the most popular items for that search term, then cache the final results using something like Memcached, Membase or similar. Am I along the right lines here?

  • Server RAID 5 failed...all I have left is my compiled website

    - by David Murdoch
    Yesterday, 2 of the 3 drives in my dev server's RAID 5 decided to die on me (with no warning). I've come to grips with the fact that my data is most likely lost unless I shell out some major bucks for professional data-resortoration. People, don't be an idiot like me and treat your RAID as a data backup! Luckily I published the site about 4 hours before my files went bye-bye. Is there any way to run some [magical] program to restore my compiled site to their original files? Also: I develop on one machine with the files stored on the server...is there some visual studio 2010 web cache on my local machine (the one that didn't crash) that I may be able to use?

  • newline in Rackspace Cron Job email

    - by senloe
    I'm running backups against multiple databases hosted at Rackspace. This is working fine. The problem I'm running into is with the results email. I'm using Response.Write to write a message to the web page which is used for logging and is also consumed by the results mail sent out by the job. The problem is I can't seem to get newlines to appear between log messages. The logfile stored on the server is correct, but only the first newline shows up in the email. The mail is in Plain Text format so I tried using "\n" and System.Environment.Newline and neither work. I also tried using <br/> with no luck. Does anybody have any ideas?

  • Where do I put constants file for Codeigniter (PHP)?

    - by wag2639
    I have a list of constants (I'm using them as an enum), some are define statements, and some are just global variables. Where am I suppose to put them in the MVC framework so I can use them for both my model and my controller that needs to reference it? I'd rather not stick it into config/constants.php since they shouldn't be called except for by this model and the controllers that use it. Edit 1: Clarification To be more specific, I have my message_model model and it has a bunch of constants that I need that are stored in message_model_constants.php. Where should I put message_model_constants.php and is there a way to have it automatically included by the controller that loads message_model when message_model is not (and I don't want it to be) auto-loaded. Edit 2: I really don't want to have the constants auto-loaded except for when I use the model

  • Manually Building a Tree in CakePHP

    - by mabwi
    I'm currently working on building an application in CakePHP. There's a quite extensive existing data set that's conceptually a tree, but wasn't previously stored as one. What I mean by that, is there's no real relationship defined in the data. The problem I'm having is getting it to work correctly with the CakePHP tree behaviour. Because I have to set all the values on existing data - as opposed to Cake setting up the structure as elements are inserted - I need to understand how the lft/rght values work. So, I guess the question is: How does the structure data work, specifically the lft/rght values? How do I set it up so that the data comes out rationally, without inserting them one at a time? It's a 2 level tree, with Sections and sub-sections. Thanks for the help

  • How to make this jpeg compression faster

    - by Richard Knop
    I am using OpenCV to compress binary images from a camera: vector<int> p; p.push_back(CV_IMWRITE_JPEG_QUALITY); p.push_back(75); // JPG quality vector<unsigned char> jpegBuf; cv::imencode(".jpg", fIplImageHeader, jpegBuf, p); The code above compresses a binary RGB image stored in fIplImageHeader to a JPEG image. For a 640*480 image it takes about 0.25 seconds to execute the five lines above. Is there any way I could make it faster? I really need to repeat the compression more than 4 times a second.

  • is it possible to write data to a collection in wpf?

    - by randyc
    Hello. In looking through samples I have seen a number of examples where it is possible to present data within a wpf applicaiton by binding to collections. However I was wondering is it possible to write to a collection from an applicaiton. Say for example i have 2 or more fields such as names and I wanted to have hte ability to add up to three names in my application ( all stored in memory). Will collections serve this purpose. In the past with asp.net I have done this by creating data tables and storing values on the fly or during the session. I am trying to learn WPF and I was wondering if collections work in the same fashion? If so could you please post an example or point me to references that show examples of this? Thank you in advance.

  • Windows Phone: Updating backend datastore (via web service) while keeping UI very responsive

    - by will
    I am developing a Windows Phone app where users can update a list. Each update, delete, add etc need to be stored in a database that sits behind a web service. As well as ensuring all the operations made on the phone end up in the cloud, I need to make sure the app is really responsive and the user doesn’t feel any lag time whatsoever. What’s the best design to use here? Each check box change, each text box edit fires a new thread to contact the web service? Locally store a list of things that need to be updated then send to the server in batch every so often (what about the back button)? Am I missing another even easier implementation? Thanks in advance,

  • Rails: Best practice to store user settings?

    - by ole_berlin
    Hi, I'm wondering what the best way is to store user settings? For a web 2.0 app I want users to be able to select certain settings. At the moment is it only when to receive email notifications. The easiest way would be to just create a Model "Settings" and have a column for every setting and then have a 1-1 relationship with users. But is there a pattern to solve this better? Is it maybe better to store the info in the user table itself? Or should I use a table with "settings_name" and "settings_value" to be completely open about the type of settings stored there (without having to run any migrations when adding options)? What is your opinion? Thanks
