  • Mysql: ROLLBACK for multiple queries

    - by Raj
    Hi I have more than three MySql queiries in a PHP script triggered by scheduled task. If a query catch an error, script throw an exception and rollback that Mysql query. It works fine. However if first query works fine, but not 2nd query, throw an exception, it rollback 2nd one but not 1st query. I am using begin_trans(), commit and rollback() for individual queries because Sometimes i need to rollback one query, sometimes all queries. Is there any way to rollback one query or all queries? Thanks in advance UPDATE: I got it working, there was no problem with in begin_trans(), commit and rollback(), the database connection config was different for one query from other queries, crazy code without any comments!!!

  • IE not triggering keyboard event on a form with ONE FIELD

    - by raj
    I'm seeing my Friend's code here... <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> </form> </BODY> </HTML> and when he tried entering a value in the textbox and pressed enter, it did not call the detectEvent(). I said, it'll always call onSubmit on enter button..... and he surprised me, <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> <p> Field1 <input type="text" id="text2"/> </p> </form> </BODY> </HTML> Now press enter, The function gets called..... Why so!? Why onKeyUp not called on forms with just one field.!!! am i missing something?

  • Parse usable Street Address, City, State, Zip from a string

    - by Rob Allen
    Problem: I have an address field from an Access database which has been converted to Sql Server 2005. This field has everything all in one field. I need to parse out the individual sections of the address into their appropriate fields in a normalized table. I need to do this for approximately 4,000 records and it needs to be repeatable. Here are the rules for this exercise: 1 - no whining about how this should have been separate fields in the first place, we are often confronted with less than ideal situations and have to make the best of them 2- for this post, use any language you want 3- feel free to play code golf 4 - Assume an address in the US (for now) 5 - assume that the input string will sometimes contain an addressee (the person being addressed) and/or a second street address (i.e. Suite B) 6 - states may be abbreviated 7 - zip code could be standard 5 digit or zip+4 8 - there are typos in some instances UPDATE: In response to the questions posed, standards were not universally followed, I need need to store the individual values, not just geocode and errors means typo (corrected above) Sample Data: A. P. Croll & Son 2299 Lewes-Georgetown Hwy, Georgetown, DE 19947 11522 Shawnee Road, Greenwood DE 19950 144 Kings Highway, S.W. Dover, DE 19901 Intergrated Const.

  • HSM - cryptoki - opening sessions overhead

    - by Raj
    I am having a query regarding sessions with HSM. I am aware that there is an overhead if you initialise and finalise the cryptoki api for every file you want to encrypt/decrypt. My queries are, Is there an overhead in opening and closing individual sessions for every file, you want to encrypt/decrypt.(C_Initialize/C_Finalize) How many maximum number of sessions can i have for a HSM simultaneously, with out affecting the performance? Is opening and closing the session for processing individual files the best approach or opening a session and processing multiple files and then closing the session the best approach? Thanks

  • specifying multiple URLs with cURL/PHP using square brackets

    - by Raj Gundu
    I have a large array of URLS similar to this: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); The cURL manual states here (http://curl.haxx.se/docs/manpage.html) that i can use square brackets '[]' to specify multiple urls. Used in the above example this would be similar to this: 'http://www.example.com/product.php?page=[1-3]&sortOn=sellprice' So far i have been unable to reference this correctly. This is the complete code segment I'm currently trying to utilize this with: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); $node_count = count($nodes); $curl_arr = array(); $master = curl_multi_init(); for($i = 0; $i < $node_count; $i++) { $url =$nodes[$i]; $curl_arr[$i] = curl_init($url); curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, true); curl_multi_add_handle($master, $curl_arr[$i]); } do { curl_multi_exec($master,$running); } while($running > 0); echo "results: "; for($i = 0; $i < $node_count; $i++) { $results = curl_multi_getcontent ( $curl_arr[$i] ); echo( $i . "\n" . $results . "\n"); echo 'done'; I can't seem to find any more documentation on this. Thanks in advance.

  • How do I manually log a user in with a MembershipProvider?

    - by Allen
    I'm experimenting with writing my own custom MembershipProvider in asp.net and I want to roll my own login page. We do some fairly special stuff at login time so we can't use the default login control so I need a way to manually log a user in. So far I haven't found anything on how to write your own login control so I'm here, wondering how I can manually log a user in via a MembershipProvider. I've tried Membership.ValidateUser("user", "pass"); and while that does call ValidateUser() on my custom MembershipProvider, and it does return true, it doesn't actually log me in. Btw I'm fairly new to the whole MembershipProvider stuff so if I'm not even on the right wavelength, feel free to let me know.

  • Running out of memory but not seeing excessive object allocation in Instruments

    - by Scotty Allen
    I have an iPad app that's crashing due to low memory. However, Instruments doesn't show any significant amount of memory allocated using ObjectAlloc - it stays under 1MB for the lifetime of the application. Leaks shows less than 1kB leaked over the course of the run. Memory monitor shows the free memory on the devices drop significantly with use, eventually dropping to the point that it's out of memory. Here's a screenshot from Instruments: I'm totally stumped. As far as I can tell, this basically says that as far as my app is concerned, I'm never using more than about 750kB, but that the device is still running out of physical memory, which is causing my app to crash/force exit. I'm new to debugging memory issues with XCode. Am I measuring this wrong? Is there another way to see where this memory is going?

  • Per-process CPU usage on Win95 / Win98 / WinME

    - by Hugh Allen
    How can you programmatically measure per-process (or better, per-thread) CPU usage under windows 95, windows 98 and windows ME? If it requires the DDK, where can you obtain that? Please note the Win9x requirement. It's easy on NT. EDIT: I tried installing the Win95/98 version of WMI, but Win32_Process.KernelModeTime and Win32_Process.UserModeTime return Null (as do most Win32_Process properties under win9x).

  • Ruby - calling constructor without arguments & removal of new line characters

    - by Raj
    I am a newbie at Ruby, I have written down a sample program. I dont understand the following: Why constructor without any arguments are not called in Ruby? How do we access the class variable outside the class' definition? Why does it always append newline characters at the end of the string? How do we strip it? Code: class Employee attr_reader :empid attr_writer :empid attr_writer :name def name return @name.upcase end attr_accessor :salary @@employeeCount = 0 def initiaze() @@employeeCount += 1 puts ("Initialize called!") end def getCount return @@employeeCount end end anEmp = Employee.new print ("Enter new employee name: ") anEmp.name = gets() print ("Enter #{anEmp.name}'s employee ID: ") anEmp.empid = gets() print ("Enter salary for #{anEmp.name}: ") anEmp.salary = gets() theEmpName = anEmp.name.split.join("\n") theEmpID = anEmp.empid.split.join("\n") theEmpSalary = anEmp.salary.split.join("\n") anEmp = Employee.new() anEmp = Employee.new() theCount = anEmp.getCount puts ("New employee #{theEmpName} with employee ID #{theEmpID} has been enrolled, welcome to hell! You have been paid as low as $ #{theEmpSalary}") puts ("Total number of employees created = #{theCount}") Output: Enter new employee name: Lionel Messi Enter LIONEL MESSI 's employee ID: 10 Enter salary for LIONEL MESSI : 10000000 New employee LIONEL MESSI with employee ID 10 has been enrolled, welcome to hell! You have been paid as low as $ 10000000 Total number of employees created = 0 Thanks
