• Oracle Date format - Strange behaviour

  - by Sauron

  I am writing a SQL query to retrive data from a table between two dates. I give two inputs as shown. I convert the Date TO_CHAR(DD/MON/YYYY). 1. StartDate > 01/SEP/2009 EndDate < 01/OCT/2009 2. StartDate > 01/SEP/2009 EndDate < 1/OCT/2009 I dont get any result for the first input. When I change it to second one i get the result. What is the difference between 01/OCT/2009 1/OCT/2009

• Why is memory management so visible in Java?

  - by Emil

  I'm playing around with writing some simple Spring-based web apps and deploying them to Tomcat. Almost immediately, I run into the need to customize the Tomcat's JVM settings with -XX:MaxPermSize (and -Xmx and -Xms); without this, the server easily runs out of PermGen space. Why is this such an issue for Java compared to other garbage collected languages? Comparing counts of "tune X memory usage" for X in Java, Ruby, Perl and Python, shows that Java has easily an order of magnitude more hits in Google than the other languages combined.

• Oracle - pl sql selecting from SYS_REFCURSOR

  - by Einstein

  I have a function that returns a SYS_REFCURSOR that has a single row but multiple columns. What I'm looking to do is to be able to have a SQL query that has nested sub-queries using the column values returned in the SYS_REFCURSOR. Alternative ideas such as types, etc would be appreciated. Code below is me writing on-the-fly and hasn't been validated for syntax. --Oracle function CREATE DummyFunction(dummyValue AS NUMBER) RETURN SYS_REFCURSOR IS RETURN_DATA SYS_REFCURSOR; BEGIN OPEN RETURN_DATA SELECT TO_CHAR(dummyValue) || 'A' AS ColumnA ,TO_CHAR(dummyValue) || 'B' AS ColumnB FROM DUAL; RETURN RETURN_DATA; END; --sample query with sub-queries; does not work SELECT SELECT ColumnA FROM DummyFunction(1) FROM DUAL AS ColumnA ,SELECT ColumnB FROM DummyFunction(1) FROM DUAL AS ColumnB FROM DUAL;

  - by Tprice88

  This is my Working Code DriftMul:=99; WriteProcessMemory(HandleWindow, ptr($4E709C), @DriftMul, 2, Write); I want to Convert it without using a variable but it wont work Below is just an Example of what i want to do.

I am able to program in a few languages and every language i use their is a way to to do this.

• Dropdowns don't work on webOS with PhoneGap?

  - by Steve Nay

  I'm trying to use a dropdown in a PhoneGap app I'm writing. It uses a simple <select>: <select> <option value="1">First</option> <option value="2">Second</option> </select> This works fine on Android and the iPhone (including behaving like a native drop-down would on those systems). However, it doesn't appear to work on webOS (neither the Palm Pre itself nor the emulator). The <select> displays properly on the screen, but when I tap on it, nothing happens--I'm not able to make a selection from the dropdown. Why might this be?

• Design guidelines for cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• Customer provider Password Reset client.

  - by ProfK

  I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.

• PHP export to text file - Only saving first line.

  - by wertz8090

  I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

• Eliminating false dependencies

  - by Klaus

  Hi all, I have a quite general question regarding false dependencies. As the name implies, those or no real dependencies and can be elimianated. I am aware of techniqes called register renaming that eliminate such dependencies at a hardware level. Of course I could eliminate those already at a "higher" level when writing assembler code that avoids false dependencies. But now I am wondering if also the compiler provides support to keep the number of false dependencies low or does it more rely on the hardware to eliminate those? Thanks

• Any good opensource SharePoint components that can abstract you from the inner SharePoint plumbings?

  - by JL

  I am looking for a good reusable set of components that can be used to communicate with SharePoint via web services, preferably open source. I want some abstraction from CAML and WebDav and SharePoint Web Services that could help me speed up my development time. Ideally I want to select, insert, update and delete from lists, manage attachments in list items, download items from sharepoint, retrieve user meta data from owner info. This sort of thing. Does any such abstraction exist for Sharepoint that use SharePoints web service model, obviously the use of the MOSS Component API is out of the question because it will only run on the hosted MOSS server, and I am writing an SOA app. Thank you

• How do you set a cookie to be accessible across the entire domain in Javascript

  - by Tzarkov

  I suppose there should be a way to set a cookie to be accessible from the entire domain nevermind from which directory you are setting the cookie. Say in mypage.com/blue/index.php y set the cookie "colour=blue;" this way: document.cookie = "colour" + "=" + "blue" + "; expires=" + expireDate.toGMTString() + "; path=/"; Using this code, the cookie retrieval function in mypage.com/home.php can't access the content of the cookie. If it was just from first level directories that the cookie needs to be set, we would be ok by doing path=../ instead of path=/ But how do you go about writing generic code that sets a cookie that is accessible from any page in that domain not minding how deep in the file structure is the page the cookie is being set from?

• File.Exists() returns false, but not in debug

  - by Tor Haugen

  I'm being completely confused here folks, My code throws an exception because File.Exists() returns false public override sealed TCargo ReadFile(string fileName) { if (!File.Exists(fileName)) { throw new ArgumentException("Provided file name does not exist", "fileName"); } Visual studio breaks at the throw statement, and I immediately check the value of File.Exists(fileName) in the immediate window. It returns true. When I drag the breakpoint back up to the if statement and execute it again, it throws again. fileName is an absolute path to a file. I'm not creating the file, nor writing to it (it's there all along). If I paste the path into the open dialog in Notepad, it reads the file without problems. The code is executing in a background worker. It's the only complicating factor I can think of. I am positive the file has not been opened already, either in the worker thread or elsewhere. What's going on here?

• Network Communication program in python

  - by lamnep

  Hi all, Basically what I'm trying to achieve is a program which allow users to connect to a each other over a network in, essentially, a chat room. What I'm currently struggling with is writing the code so that the users can connect to each other without knowing the IP-address of the computer that the other users are using or knowing the IP-address of a server. Does anyone know of a way in which I could simply have all of the users scan the IP range of my network in order to find any active 'room' and then give the user a chance to connect to it? Also, the hope is that there will be no need for a central server to run this from, rather every user will simply be connected to all other user, essentially being the server and client at the same time.

• DeferWindowPos and SWP_SHOWWINDOW/SWP_HIDEWINDOW

  - by Tom Bell

  I am writing a virtual desktop application which utilises the DeferWindowPos API functions. The current method I am using is moving the windows off the screen if they're not on the current virtual desktop. However I know wish to also hide the windows that are off-screen so they do not appear on the task bar. I have attempted this by also passing SWP_SHOWWINDOW/SWP_HIDEWINDOW to the DeferWindowPos() calls. I have read a few sites regarding this and one of them suggested that if SWP_SHOWWINDOW/SWP_HIDEWINDOW are passed, then the window will only show or hide, and no reposition. Can anyone confirm this, or am I doing something wrong?

• How can I measure file access performance (and volume) of a (Java) application

  - by stmoebius

  Given an application, how can I measure the amount of data read and written by that application? the time spent reading/writing to disk? The specific application is Java-based (JBoss), and multi-threaded, and running as a service on Windows 7/2008 x64. The overall goal I have is determining whether and why file access is a bottleneck in my application. Therefore, running the application in a defined and repeatable scenario is a given. File access may be local as well as on network shares. Windows performance monitor appears to be too hard to use (unless someone can point me to a helpful explanation). Any ideas?

• Tools for viewing logs of unlimited size

  - by jkff

  It's no secret that application logs can go well beyond the limits of naive log viewers, and the desired viewer functionality (say, filtering the log based on a condition, or highlighting particular message types, or splitting it into sublogs based on a field value, or merging several logs based on a time axis, or bookmarking etc.) is beyond the abilities of large-file text viewers. I wonder: Whether decent specialized applications exist (I haven't found any) What functionality might one expect from such an application? (I'm asking because my student is writing such an application, and the functionality above has already been implemented to a certain extent of usability)

• Command to surround a character with spaces in vim

  - by William Becker

  I am trying to use vim properly - to aid me I've mapped my arrow keys to "" so that I am forced to use {hjlk} to move around. This is causing me a problem when I want to just surround a character with spaces, eg: "2+3" is better formatted "2 + 3" Previously I would have put my cursor over the + and typed: i[space][arrow-right][space][Esc] That's 5 presses. To do this without the arrow I seem to need to put the cursor over the + and go: i[space][Esc]lli[space][Esc] That's 8 presses. I can convert the "li" into an "a" which reduces it to 7 presses: i[space][Esc]la[space][Esc] Short of writing this into a macro is there a better way of doing it? Is there some magic vim command which will allow me to do it in less than even 5 presses - and some way to generalise it so that I can do it to entire words or symbols, eg if I want to convert 3==4 to 3 == 4?

• Android: how do i custom arrange menu items?

  - by mtmurdock

  I would like to arrange the menu items in my app so that one item appears in its own line, and the other 3 items appear below it. I know that this is possible because i have seen apps do it. I tried writing a menu xml with linear layouts to arrange the items, but this doesnt work. I have also tried putting them in different groups, but I had no luck with that either. I know that this is possible: i have seen it done. Anyone have any ideas?

• Which kind of method signature do you prefer and why?

  - by devoured elysium

  Ok, this is probably highly subjective but here it comes: Let's assume I'm writing a method that will take a printscreen of some region of the screen. Which method signature would you prefer and why? Bitmap DoPrintScreen(int x, int y, int width, int height); Bitmap DoPrintScreen(Rectangle rect); Bitmap DoPrintScreen(Point point, Size size); Other Why? I keep seeing myself repeatedly implementing both 1) and 2) (redirecting one of them to the other) but I end up usually just using one of them, so there really is no point in having both. I can't decide which would be better. Maybe I should use the signature that looks the most with the method I'll be calling to make the printscreen?

• How to make sure the value is reset in foreach loop in PHP

  - by kwokwai

  Hi all, I was writing a simple PHP page and a few foreach loops were used. Here are the scripts: $arrs = array("a", "b", "c"); foreach ($arrs as $arr) { if(substr($arr,0,1)=="b") { echo "This is b"; } } // ends of first foreach loop and I didn't use ifelse here And when this foreach ends, I wrote another foreach loop in which all the values in the foreach loop was the same as previous foreach. foreach ($arrs as $arr) { if(substr($arr,0,1)=="c") { echo "This is c"; } } I am not sure if it is a good practice to have two foreach loops with same values and keys. Will the values get overwritten in the first foreach loop?

• Equivalent for Java's System.getProperty("java.io.tmpdir") in C ?

  - by B_

  As the title says, the java.io.tmpdir property in Java is really nice, and I can't find an equivalent for C. I'm writing for Windows and in Visual Studio. I don't want to just use something like C:\Temp because in later versions of windows the appropriate directory could be something like C:\Users\[UserName]\AppData\Local\Temp and a way to retrieve this would be much easier. I want a directory and not just a temp file because I'm downloading and executing a file from the internet. As a side note, if anyone can give me tips about how to better google for C stuff it would be much appreciated :)

• How can I inherit form and access controls from mother form?

  - by kasia

  Hi, I'm in the middle of writing my project and I have this problem: I try to write a library and I want to use it in my application. In library I have a form with menu strip, tool bar, list view, tree view and etc. Everything in library is protected. In my application I have created the form which inherit form the library. I can change and add new functionality to list view and tree view using designer panel in VS 2008 but I don't have access to menu strip and tool bar, even though they are protected. Why is that so? I will be thankful for some advice.

• Pseudorandom Number Generation with Specific Non-Uniform Distributions

  - by carnun

  Hello all, I'm writing a program that simulates various random walks (with differing distributions). At each timestep, I need randomly generated, two dimensional step distances and angles from the distribution of the random walk. I'm hoping someone can check my understanding of how to generate these random numbers. As I understand it I can use Inverse Transform Sampling as follows: If f(x) is the pdf of our random walk that has a non-uniform distribution, and y is a random number from a uniform distribution. Then if we let f(x) = y and solve to find x then we have a random number from the non-uniform distribution. Is this a feasible solution?

• How do i change the address of a New struct in a loop?!

  Hi guys, i'm writing a simple code which is about polynomials using link lists in C#. the problem i have is that whenever it creates a new struct (node) in the for loop it gives it the same address as the previous node was given. so how do i fix it ? here is my struct : struct poly { public int coef; public int pow; public poly* link;} ; and here is the where the problem occurs: for (; i < this.textBox1.Text.Length; i++) { q = new poly(); ...... p->link = &q; } &q remains unchanged !
