[MySQL] Load data from .csv applying regex before insert into table

- by Gabriel L. Oliveira

I know that there is a code to import .csv data into a mysql table, and I'm using this one: LOAD DATA INFILE "file.csv" INTO TABLE foo FIELDS TERMINATED BY "," LINES TERMINATED BY "\\r\\n"; The data inside this .csv are lines like this example: 08/e0/Breast_Cancer_Res_2001_Nov_2_3(1)_55-60.tar.gz Breast Cancer Res. 2001 Nov 2; 3(1):55-60 PMC13900 b0/ac/Breast_Cancer_Res_2001_Nov_9_3(1)_61-65.tar.gz Breast Cancer Res. 2001 Nov 9; 3(1):61-65 PMC13901 I just want the first part (the .tar.gz path), always on the pattern (letter or number)(letter or number) / (letter or number)(letter or number)/... and the part starting by 'PMC', always on the pattern PMC(number...) where 'number' means a number between 0 to 9 and a letter means a letter between a to z (both upper and lower case) So, applying the LOAD DATA, and the regex, and inserting the result entries on my sql table, the result table should be: 1 08/e0/Breast_Cancer_Res_2001_Nov_2_3(1)_55-60.tar.gz PMC13900 2 b0/ac/Breast_Cancer_Res_2001_Nov_9_3(1)_61-65.tar.gz PMC13901 What should be the SQL command to do all this?

How can I prevent infinite recursion when using events to bind UI elements to fields?

- by Billy ONeal

The following seems to be a relatively common pattern (to me, not to the community at large) to bind a string variable to the contents of a TextBox. class MyBackEndClass { public event EventHandler DataChanged; string _Data; public string Data { get { return _Data; } set { _Data = value; //Fire the DataChanged event } } } class SomeForm : // Form stuff { MyBackEndClass mbe; TextBox someTextBox; SomeForm() { someTextBox.TextChanged += HandleTextBox(); mbe.DataChanged += HandleData(); } void HandleTextBox(Object sender, EventArgs e) { mbe.Data = ((TextBox)sender).Text; } void HandleData(Object sender, EventArgs e) { someTextBox.Text = ((MyBackEndClass) sender).Data; } } The problem is that changing the TextBox fires the changes the data value in the backend, which causes the textbox to change, etc. That runs forever. Is there a better design pattern (other than resorting to a nasty boolean flag) that handles this case correctly? EDIT: To be clear, in the real design the backend class is used to synchronize changes between multiple forms. Therefore I can't just use the SomeTextBox.Text property directly. Billy3

Console Application Structure

- by Paul Fox

I've written several .Net Console Applications over the past 6 months and we have many more throughout different projects in our organization. I generally stick to the same standard format/structure for my Console Applications. Unfortunately, many of our console applications do not. I have been looking into ways of standardizing the structure of these Console Applications. I would also like to provide a framework for the basic structure of a Console Application and provide easy access to standard ways of handling things such as argument passing, logging, etc. Can anyone suggest Best Practices for addressing these concerns? I have been reading this MSDN article on Console Applications in .Net which suggests a Design Pattern for Console Apps. The example uses a Template Method pattern to handle some of the concerns I listed earlier. Two negatives of using this approach are listed in the article. Ending up with twice as many classes Having many simple, similar classes Can anyone suggest better, or more standard, ways of handling this? What about listing additional negatives with this approach?

PHP contact form, am I doing it wrong?

- by decimal

I'm learning PHP and I'm trying to write a simple email script. I have a function (checkEmpty) to check if all the forms are filled in and if the email adress is valid (isEmailValid). I'm not sure how to return true checkEmpty funciton. Here's my code: When the submit button is clicked: if (isset($_POST['submit'])) { //INSERT FORM VALUES INTO AN ARRAY $field = array ('name' => $_POST['name'], 'email' => $_POST['email'], 'message' => $_POST['message']); //CONVERT ARRAY KEYS TO VARIABLE NAMES extract ($field); checkEmpty($name, $email, $message); function checkEmpty($name, $email, $message) { global $name_error; global $mail_error; global $message_error; //CHECK IF NAME FIELD IS EMPTY if (isset($name) === true && empty($name) === true) { $name_error = "<span class='error_text'>* Please enter your name</span>"; } //CHECK IF EMAIL IS EMPTY if (isset($email) === true && empty($email) === true) { $mail_error = "<span class='error_text'>* Please enter your email address</span>"; //AND IF IT ISN'T EMPTY CHECK IF IT IS A VALID ONE } elseif (!isValidEmail($email)) { $mail_error = "<span class='error_text'> * Please enter a valid email</span>"; } //CHECK IF MESSAGE IS EMPTY if (isset($message) === true && empty($message) === true) { $message_error = "<span class='error_text'>* Please enter your message</span>"; } } // This function tests whether the email address is valid function isValidEmail($email){ $pattern = "^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$"; if (eregi($pattern, $email)) { return true; } else { return false; } } I know I shouldn't be using globals in the function, I don't know an alternative. The error messages are display beside each form element.

Setting up App Engine to receive email addresses with ids in the address

- by Mark M

I am writing an App Engine app that is supposed to receive emails in this form: [email protected] (someID is an alphanumeric ID that I generate). I have this in my web.xml thinking it would catch emails that start with 'addcontact.': <servlet> <servlet-name>addNewContactServlet</servlet-name> <servlet-class>com.mycompany.server.AddNewContactServlet</servlet- class> </servlet> <servlet-mapping> <servlet-name>addNewContactServlet</servlet-name> <url-pattern>/_ah/mail/addcontact.*</url-pattern> </servlet-mapping> However, both on my dev machine and on google's servers email is not received. On the dev machine I get this message (I get a similar error in the deployed log) Message send failure HTTP ERROR 404 Problem accessing /_ah/mail/ [email protected]. Reason: NOT_FOUND I can receive email at fully specified addresses or when I use /_ah/mail/* The google documentation made me believe it was possible to include partial email addresses in web.xml. Am I not using the wildcard correctly? Does the period have something to do with it? Can this be done somehow?

capture text, including tags from string, and then reorder tags with text

- by Brian

I have the following text: abcdef<CONVERSION>abcabcabcabc<2007-01-12><name1><2007-01-12>abcabcabcabc<name2><2007-01-11>abcabcabcabc<name3><2007-02-12>abcabcabcabc<name4>abcabcabcabc<2007-03-12><name5><date>abcabcabcabc<name6> I need to use regular expressions in order to clean the above text: The basic extraction rule is: <2007-01-12>abcabcabcabc<name2> I have no problem extracting this pattern. My issue is that within th text I have malformed sequences: If the text doesn't start with a date, and end with a name my extraction fails. For example, the text above may have several mal formed sequences, such as: abcabcabcabc<2007-01-12><name1> Should be: <2007-01-12>abcabcabcabc<name1> Is it possible to have a regular expression that would clean the above, prior to extracting my consistent pattern. In short, i need to find all mal formed patterns, and then take the date tag and put it in front of it, as provided in the example above. Thanks.

DCI: How to implement Context with Dependency Injection?

- by ciscoheat

Most examples of a DCI Context are implemented as a Command pattern. When using Dependency Injection though, it's useful to have the dependencies injected in the constructor and send the parameters into the executing method. Compare the Command pattern class: public class SomeContext { private readonly SomeRole _someRole; private readonly IRepository<User> _userRepository; // Everything goes into the constructor for a true encapsuled command. public SomeContext(SomeRole someRole, IRepository<User> userRepository) { _someRole = someRole; _userRepository = userRepository; } public void Execute() { _someRole.DoStuff(_userRepository); } } With the Dependency injected class: public class SomeContext { private readonly IRepository<User> _userRepository; // Only what can be injected using the DI provider. public SomeContext(IRepository<User> userRepository) { _userRepository = userRepository; } // Parameters from the executing method public void Execute(SomeRole someRole) { someRole.DoStuff(_userRepository); } } The last one seems a bit nicer, but I've never seen it implemented like this so I'm curious if there are any things to consider.

How to set up WebLogic 10.3.3. security for JAX_WS web services?

- by Roman Kagan

I have quite simple task to accomplish - I have to set up the security for web services ( basic authentication with hardcoded in WLES user id and password). I set the web.xml (see code fragment below) but I have tough time configuring WebLogic. I added IdentityAssertionAuthenticator Authentication Provider, set it as Required, modified DefaultAuthenticator as Optional and I went to deployed application's security and set the role to "thisIsUser" and at some point it worked, but not anymore (I redeployed war file and set web service security the same way but no avail.) I'd greatly appreciate for all your help. <security-constraint> <display-name>SecurityConstraint</display-name> <web-resource-collection> <web-resource-name>ABC</web-resource-name> <url-pattern>/ABC</url-pattern> </web-resource-collection> <auth-constraint> <role-name>thisIsUser</role-name> </auth-constraint> </security-constraint>

Using placeholders/variables in a sed command

- by jesse_galley

I want to store a specific part of a matched result as a variable to be used for replacement later. I would like to keep this in a one liner instead of finding the variable I need before hand. when configuring apache, and use mod_rewrite, you can specificy specific parts of patterns to be used as variables,like this: RewriteRule ^www.example.com/page/(.*)$ http://www.example.com/page.php?page=$1 [R=301,L] the part of the pattern match that's contained inside the parenthesis is stored as $1 for use later. So if the url was www.example.com/page/home, it would be replaced with www.example.com/page.php?page=home. So the "home" part of the match was saved in $1 because it was the part of the pattern inside the parenthesis. I want something like this functionality with a sed command, I need to automatically replace many strings in a SQL dump file, to add drop table if exist commands before each create table, but I need to know the table name to do this, so if the dump file contains something like: ... CREATE TABLE `orders` ... I need to run something like: cat dump.sql | sed "s/CREATE TABLE `(.*)`/DROP TABLE IF EXISTS $1\N CREATE TABLE `$1`/g" to get the result of: ... DROP TABLE IF EXISTS `orders` CREATE TABLE `orders` ... I'm using the mod_rewrite syntax in the sed command as a logical example of what I'm trying to do. Any suggestions?

CSS file in a Spring WAR returns a 404

- by Rachel G.

I have a J2EE application that I am building with Spring and Maven. It has the usual project structure. Here is a bit of the hierarchy. MyApplication src main webapp WEB-INF layout header.jsp styles main.css I want to include that CSS file in my JSP. I have the following tag in place. <c:url var="styleSheetUrl" value="/styles/main.css" /> <link rel="stylesheet" href="${styleSheetUrl}"> When I deploy the application, the CSS page isn't being located. When I view the page source, the href is /MyApplication/styles/main.css. Looking inside the WAR, there is a /styles/main.css. However, I get a 404 when I try to access the CSS file directly in the browser. I discovered that the reason for the issue was the Dispatcher Servlet mapping. The mapping looks as follows. <servlet-mapping> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> I imagine the Dispatcher Servlet doesn't know how to handle the CSS request. What is the best way to handle this issue? I would rather not have to change all of my request mappings.

Java: I've created a list of word objects to include the name and the frequency, but having trouble

- by adam08

Hi Everyone, I'm working on a project which has a dictionary of words and I'm extracting them and adding them to an ArrayList as word objects. I have a class called Word as below. What I'm wondering is how do I access these word objects to update the frequency? As part of this project, I need to only have one unique word, and increase the frequency of that word by the number of occurrences in the dictionary. Word(String word) { this.word = word; this.freq = 0; } public String getWord() { return word; } public int getFreq() { return freq; } public void setFreq() { freq = freq + 1; } This is how I am adding the word objects to the ArrayList...I think it's ok? String pattern = "[^a-zA-Z\\s]"; String strippedString = line.replaceAll(pattern, ""); line = strippedString.toLowerCase(); StringTokenizer st = new StringTokenizer(line); while (st.hasMoreTokens()) { String newWord = st.nextToken(); word.add(new Word(newWord)); count++; }

Parsing an XML string containing " " (which must be preserved)

- by Zoodor

I have code that is passed a string containing XML. This XML may contain one or more instances of   (an entity reference for the blank space character). I have a requirement that these references should not be resolved (i.e. they should not be replaced with an actual space character). Is there any way for me to achieve this? Basically, given a string containing the XML: <pattern value="[A-Z0-9 ]" /> I do not want it to be converted to: <pattern value="[A-Z0-9 ]" /> (What I am actually trying to achieve is to simply take an XML string and write it to a "pretty-printed" file. This is having the side-effect of resolving occurrences of   in the string to a single space character, which need to be preserved. The reason for this requirement is that the written XML document must conform to an externally-defined specification.) I have tried creating a sub-class of XmlTextReader to read from the XML string and overriding the ResolveEntity() method, but this isn't called. I have also tried assigning a custom XmlResolver.

Java / Spring MVC 3 validation of an email address

- by Tim

I have a Java backend with Spring MVC and I am using validation in this way on my domain object for an email address: import javax.validation.constraints.NotNull; import javax.validation.constraints.Pattern; import javax.validation.constraints.Size; ... @NotNull @Size(min = 1, max = 100) @Pattern(regexp="^([a-zA-Z0-9\\-\\.\\_]+)'+'(\\@)([a-zA-Z0-9\\-\\.]+)'+'(\\.)([a-zA-Z]{2,4})$") private String email; But all I get with these lines of code Set<ConstraintViolation<Person>> failures = validator.validate(personObject); ... Map<String, String> failureMessages = new HashMap<String, String>(); for (ConstraintViolation<Person> failure : failures) { failureMessages.put(failure.getPropertyPath().toString(), failure.getMessage()); System.out.println(failure.getPropertyPath().toString()+" - "+failure.getMessage()) } I get this on the console: email - must match "^([a-zA-Z0-9\\-\\.\\_]+)'+'(\\@)([a-zA-Z0-9\\-\\.]+)'+'(\\.)([a-zA-Z]{2,4})$" but I have as email address [email protected], so the regexp does not match. So I have two prolems: What's wrong here? And how can I define a error message on my own, because display this to the user, that is not a good thing :-) Thank you in advance for your help and Best Regards.

matching images inside a link in regex

- by user225269

What is wrong with regex pattern that I created: $link_image_pattern = '/\<a\shref="([^"]*)"\>\<img\s.+\><\/a\>/'; preg_match_all($link_image_pattern, $str, $link_images); What I'm trying to do is to match all the links which has images inside of them. But when I try to output $link_images it contains everything inside the first index: <pre> <?php print_r($link_images); ?> </pre> The markup looks something like this: Array ( [0] = Array ([0] = " <p> </p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p> But when outputting the contents of the matches, it simply returns the first string that matches the pattern plus all the other markup in the page like this: <a href="{$image_url}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url}" width="568" height="347"></a></p> <p> </p> <p><strong><a href="url">Title</a></strong></p> <p>Desc</p> <p><a href="{$image_url2}"><img style="background-image:none;padding-left:0;padding-right:0;display:inline;padding-top:0;border-width:0;" title="image" border="0" alt="image" src="{$image_url2}" width="569" height="409"></a></p>")

How to keep jquery from descending too far?

- by Earlz

Hello, I am having a problem with jquery going a bit too far on pattern matching of CSS classes and IDs. I have some markup that looks like this: <div id="blah"> <div class="level2"> <input type="text" /> </div> <div class="levelA"> <div class="level2"> <input type="text" value="foo"/> </div> </div> </div> <input type="text" value="bar" /> I want for the 3 inputs to say Hello Foo Bar so I have this line of jquery: $('#blah .level2 input').val('hello'); the problem now is that jquery is a bit too liberal in it's pattern matches and matches both the first and second. How can I prevent this kind of thing from happening? A live example is at http://jsbin.com/opelo3/4

Fastest method to define whether a number is a triangular number

- by psihodelia

A triangular number is the sum of the n natural numbers from 1 to n. What is the fastest method to find whether a given positive integer number is a triangular one? I suppose, there must be a hidden pattern in a binary representation of such numbers (like if you need to find whether a number is even/odd you check its least significant bit). Here is a cut of the first 1200th up to 1300th triangular numbers, you can easily see a bit-pattern here (if not, try to zoom out): (720600, '10101111111011011000') (721801, '10110000001110001001') (723003, '10110000100000111011') (724206, '10110000110011101110') (725410, '10110001000110100010') (726615, '10110001011001010111') (727821, '10110001101100001101') (729028, '10110001111111000100') (730236, '10110010010001111100') (731445, '10110010100100110101') (732655, '10110010110111101111') (733866, '10110011001010101010') (735078, '10110011011101100110') (736291, '10110011110000100011') (737505, '10110100000011100001') (738720, '10110100010110100000') (739936, '10110100101001100000') (741153, '10110100111100100001') (742371, '10110101001111100011') (743590, '10110101100010100110') (744810, '10110101110101101010') (746031, '10110110001000101111') (747253, '10110110011011110101') (748476, '10110110101110111100') (749700, '10110111000010000100') (750925, '10110111010101001101') (752151, '10110111101000010111') (753378, '10110111111011100010') (754606, '10111000001110101110') (755835, '10111000100001111011') (757065, '10111000110101001001') (758296, '10111001001000011000') (759528, '10111001011011101000') (760761, '10111001101110111001') (761995, '10111010000010001011') (763230, '10111010010101011110') (764466, '10111010101000110010') (765703, '10111010111100000111') (766941, '10111011001111011101') (768180, '10111011100010110100') (769420, '10111011110110001100') (770661, '10111100001001100101') (771903, '10111100011100111111') (773146, '10111100110000011010') (774390, '10111101000011110110') (775635, '10111101010111010011') (776881, '10111101101010110001') (778128, '10111101111110010000') (779376, '10111110010001110000') (780625, '10111110100101010001') (781875, '10111110111000110011') (783126, '10111111001100010110') (784378, '10111111011111111010') (785631, '10111111110011011111') (786885, '11000000000111000101') (788140, '11000000011010101100') (789396, '11000000101110010100') (790653, '11000001000001111101') (791911, '11000001010101100111') (793170, '11000001101001010010') (794430, '11000001111100111110') (795691, '11000010010000101011') (796953, '11000010100100011001') (798216, '11000010111000001000') (799480, '11000011001011111000') (800745, '11000011011111101001') (802011, '11000011110011011011') (803278, '11000100000111001110') (804546, '11000100011011000010') (805815, '11000100101110110111') (807085, '11000101000010101101') (808356, '11000101010110100100') (809628, '11000101101010011100') (810901, '11000101111110010101') (812175, '11000110010010001111') (813450, '11000110100110001010') (814726, '11000110111010000110') (816003, '11000111001110000011') (817281, '11000111100010000001') (818560, '11000111110110000000') (819840, '11001000001010000000') (821121, '11001000011110000001') (822403, '11001000110010000011') (823686, '11001001000110000110') (824970, '11001001011010001010') (826255, '11001001101110001111') (827541, '11001010000010010101') (828828, '11001010010110011100') (830116, '11001010101010100100') (831405, '11001010111110101101') (832695, '11001011010010110111') (833986, '11001011100111000010') (835278, '11001011111011001110') (836571, '11001100001111011011') (837865, '11001100100011101001') (839160, '11001100110111111000') (840456, '11001101001100001000') (841753, '11001101100000011001') (843051, '11001101110100101011') (844350, '11001110001000111110') For example, can you also see a rotated normal distribution curve, represented by zeros between 807085 and 831405?

Simple syntax question

- by stabby

Hey everyone, First off, sorry for my noob-ness. Believe me when i say ive been rtfm'ing. Im not lazy, im just dumb (apparently). On the bright side, this could earn someone some easy points here. I'm trying to do a match/replace with a pattern that contains special characters, and running into syntax errors in a Flex 3 app. I just want the following regex to compile... (while also replacing html tags with "") value.replace(/</?\w+((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)/?>/g, ""); On a side note, the pattern /<.*?/g wouldn't work in cases where there are html entities between tags, like so: <TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0"><one</FONT> </P> </TEXTFORMAT><TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0">two</FONT> </P> </TEXTFORMAT> The first regex would get both "<one" and "two", but the second would only get "hi" Thanks!

What does this SAP error mean? recv104 NiIReadrecv nixxi.cp5087

- by Techboy

I have an SAP BI Portal system and an SAP BW system. In the Visual Administrator of the BI Portal, section 'JCo RFC Provider' I have created some RFC listeners. In the SAP BW system (in transaction SM59), I have created, tested and activated the relevant RFC connections. When I start a JCo RFC Provider in the BI Portal the BW system that it communicates with produces these errors (displayed from SAP transaction SM21): Operating system call recv failed (error no. 104 ) Module nam Line Error text Caller.... Reason/cal nixxi.cp 5087 recv104 NiIRead recv Documentation for system log message Q0 I : The specified operating system call was returned with an error. For communication calls (receive, send, etc) often the cause of errors are network problems. It could also be a configuration problem at operating system level.

Additional specifications for error number 104 Name for errno number E_UNKNOWN_NO The meaning of the value stored in 'errno' is platform-dependent.

Word 2010 Crashing

- by Flymo

We have an office with all users using the same spec'ed PCs with the same Image deployed to them, so that the software and configuration is identical. I have one user whos keeps having the install of MS Word 2010 crash intermittently. First i reinstalled Office 2010 Suite, but will have the crashes. The PC has been replaced with a clean install of Windows and Office but we are still having the issues with Word crashing. We have had the user to log onto another PC which we know to be working fine, but again, Word keeps crashing. Below is the Error from EventViewer: Faulting application name: WINWORD.EXE, version: 14.0.6024.1000, time stamp: 0x4d83e310 Faulting module name: MSVCR90.dll, version: 9.0.30729.6161, time stamp: 0x4dace5b9 Exception code: 0xc0000417 Fault offset: 0x000320f0 Faulting process id: 0xc34 Faulting application start time: 0x01cd1881ea917c33 Faulting application path: C:\Program Files\Microsoft Office\Office14\WINWORD.EXE Faulting module path: C:\Windows\WinSxS\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.6161_none_50934f2ebcb7eb57\MSVCR90.dll Report Id: edd97602-8477-11e1-aa13-001111db42bf The PC is running Windows 7 Professional and Office 2010 We have tried everything we can think of. If anyone could enlighten us, it would be very much appretiated. Cheers

DriveImage XML fails with a Windows Volume Shadow Service Error

- by Ssvarc

I'm trying to image a SATA laptop hard drive, using DriveImageXML, that is attached to my computer via a USB adapter. I'm running Win7 Ultimate 64 bit. DriveXML is returning: Could not initialize Windows Volume Shadow Service (VSS). ERROR C:\Program Files (x86)\Runtime Software\Drivelmage XML\vss64.exe failed to start. ERROR TIMEOUT Make sure VSSVC.EXE is running in your task manager. Click Help for more information. VSSVC.EXE is running in Task Manager, as is VSS64.exe. Looking at the FAQ on the Runtime webpage this turned up: Please verify in Settings-Control Panel-Administrative Tools-Services that the following services are enabled: MS Software Shadow Copy Provider Volume Shadow Copy Also make sure you are able to stop and start these services. Possible reasons for VSS failures: For VSS to work, at least one volume in your computer must be NTFS. If you use only FAT drives, VSS will not function. The required NTFS volume does not need to be identical with the volume you want to image. You should make sure that VSSVC.EXE is running in your task manager. If the problems persist, registering "oleaut.dll" and "oleaut32.dll" using "regsvr32" might help. Both of those services are running and can be started and stopped without issue. Using "regsvr32" to register ""oleaut32.dll" returns successful, but "oleaut.dll" returns: The module "oleaut.dll" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found. Some other information that might be relevant. Browsing to the drive is successful, but accessing certain folders returns an "access" error. Windows runs a permissions adder that adds the current user profile to the NFTS permissions. Could this be the cause of the issue? DriveImage XML is running as Administrator. Thoughts?

ADODB DB2 DSN using IBMDADB2 provider

- by Eli Sand

I have a very bizarre issue with trying to establish a working connection to an IBM DB2 server from Classic ASP using ADODB. On my development server I am running IIS and have a local instance of DB2 running. When I create a system DSN on this server and try to connect to it with ADODB, I have to specify Provider=IBMDADB2; in my connection along with the DSN name - failure to include the provider and my connection won't work. On my production server(s), I have one running IIS and a second system running an instance of DB2. When I create a system DSN on the production IIS server and try to connect to it with ADODB, I cannot specify the provider, otherwise it throws an uncatchable error in an external module (I assume it's referring to the DB2 module) if I try to do anything past get a connection (oddly, opening the connection itself doesn't throw an error - but if I run a query it does). If I remove the Provider=IBMDADB2; from the connection string (thus I just have DSN=some_name), it works fine. On both systems I can verify through the ODBC connection manager that the DSN's work and can connect to the databases, and on both systems I have made sure to set the correct (only) instance of DB2 as the default. Can anyone tell me why I have to have different connection strings for the development and production servers? I would like to be able to use the same connection string for both environments if at all possible. If that means either specifying a provider for both, or for neither I don't care which - I would just like to know what's going on and how to fix it.

Mac OS X 10.6 Setup for Apache/MySQL/Perl

- by Russell C.

I just got a new Mac and have been trying to setup a local development environment for my perl applications for a few days now with no luck. I'm getting no where fast so I hope someone else who has done this successfully could help. I started by installing MAMP which I thought would take care of everything for me but unfortunately it doesn't take care of some important perl modules. I used CPAN to install all our required modules except that it seems DBD::mysql doesn't install correctly through CPAN. After reading a lot online, lots of people reported problems with this and recommended using MacPorts to install the module which I have tried doing with no luck using the following command: sudo port install p5-dbd-mysql After what seems like a successful install of DBD::mysql, Apache continues to report the following error when trying to run any of our Perl scripts: [Fri Apr 30 18:51:07 2010] [error] [client 127.0.0.1] install_driver(mysql) failed: Can't locate DBD/mysql.pm in @INC (@INC contains: /Library/Perl/Updates/5.10.0/darwin-thread-multi-2level /Library/Perl/Updates/5.10.0 /System/Library/Perl/5.10.0/darwin-thread-multi-2level /System/Library/Perl/5.10.0 /Library/Perl/5.10.0/darwin-thread-multi-2level /Library/Perl/5.10.0 /Network/Library/Perl/5.10.0/darwin-thread-multi-2level /Network/Library/Perl/5.10.0 /Network/Library/Perl /System/Library/Perl/Extras/5.10.0/darwin-thread-multi-2level /System/Library/Perl/Extras/5.10.0 .) at (eval 1835) line 3. [Fri Apr 30 18:51:07 2010] [error] [client 127.0.0.1] Perhaps the DBD::mysql perl module hasn't been fully installed, [Fri Apr 30 18:51:07 2010] [error] [client 127.0.0.1] or perhaps the capitalisation of 'mysql' isn't right. [Fri Apr 30 18:51:07 2010] [error] [client 127.0.0.1] Available drivers: DBM, ExampleP, File, Gofer, Proxy, SQLite, Sponge. I'm not sure where to go from here but my Mac isn't much of a development environment if Perl isn't able to talk to the database. I'd really appreciate any help and advice you might be able to provide in getting my system setup successfully. Thanks in advance!
