• bufferTime on OSMF

  - by Ronnie

  I am having an issue with OSMF. I have an MP4 that is 40MB. It is being progressively loaded. My issue is the video wont begin playing until the video has fully loaded. I am testing this on a web server. Any idea what's going on or what I am not doing? var mps:MediaPlayerSprite = new MediaPlayerSprite(); mps.x = 159; mps.y = 53; mps.width = 512; mps.height = 288; mps.resource = new URLResource("resources/video/3.4.1.mp4"); addChild(mps); I've even tried adding mps.mediaPlayer.bufferTime = 1; but no luck. I've even tried 0.

This need arised while talking to a friend about management and he brought up management terms that I wasn't aware of (eg. KPI, ...)

• How to use OptionParse to allow only one flag

  - by dorelal

  There are only three ways to invoke install.sh ./install.sh ./install.sh --force ./install.sh -f I can write it easily. However I am trying to make use of OptionParse. This is what I have so far. def self.parse option = {} optparse = OptionParser.new do |opts| opts.banner = "Usage: ./install.sh [--force]" opts.on('-f', '--force', '') do |dir| option[:force] = true end end begin optparse.parse! rescue OptionParser::InvalidOption => e puts e end end How do I provide feedback to user in case user provides something other than -f or --force.

• Passing an array of data as an input parameter to an Oracle procedure

  - by Sathya

  I'm trying to pass an array of (varchar) data into an Oracle procedure. The Oracle procedure would be either called from SQL*Plus or from another PL/SQL procedure like so: BEGIN pr_perform_task('1','2','3','4'); END; pr_perform_task will read each of the input parameters and perform the tasks. I'm not sure as to how I can achieve this. My first thought was to use an input parameter of type varray but I'm getting Error: PLS-00201: identifier 'VARRAY' must be declared error, when the procedure definiton looks like this: CREATE OR REPLACE PROCEDURE PR_DELETE_RECORD_VARRAY(P_ID VARRAY) IS To summarize, how can I pass the data as an array, let the SP loop through each of the parameters and perform the task ? I'm using Oracle 10gR2 as my database.

• Implement the Combine function using templates

  - by gkid123

  any idea on how to do it for template? thanks Implement the Combine function using templates. The Combine fn applies a function of two arguments cumulatively to the items of an STL container, from begin() to end(), so as to reduce the sequence to a single value. For example, Combine(<list containing 6,3,1,9,7>, std::plus<int>()) should calculate ((((6+3)+1)+9)+7). class NotEnoughElements {}; template <typename Container, typename Function> typename Container::value_type Combine(const Container& c, Function fn) throw (NotEnoughElements) { your code goes here }

• ShellExecute not working from IDE but works otherwise.

  - by Altar

  I want to create and then open a txt file using the ShellExecute command. I have used this code for years with Delphi 7 and it worked: function Executa(CONST ExeName, Parameters: string): Boolean; begin if Parameters= '' then Result:= ShellExecute(0, 'open', PChar(ExeName), NIL , nil, SW_SHOWNORMAL)> 32 else Result:= ShellExecute(0, 'open', PChar(ExeName), PChar(Parameters), nil, SW_SHOWNORMAL)> 32; end; Now, I switch to Windows 7 (don't like it; they stuck it on my throat with my new laptop) 64 bit and the code is not working anymore when it runs from IDE. Delhi shows the CPU window with the caption "CPU-Process unknown (2352)". I close the CU windows and everything works fine until I close the application, when Delphi shows the CPU window one more time. If I run the app from outside IDE, it works fine. Looks like the debugger has something to say to me, but I don't know what.

• Adding a calculated field to a Query at run time.

  - by JamesB

  I'm getting data using a query in Delphi, and would like to add a calculated field to the query before it runs. The calculated field is using values in code as well as the query so I can't just calculate it in SQL. I know I can attach an OnCalcFields Event to actually make the calculation, but the problem is after adding the calculated field there are no other fields in the query... I did some digging and found that all of the field defs are created but the actual fields are only created if DefaultFields then CreateFields Default Fields is specified procedure TDataSet.DoInternalOpen; begin FDefaultFields := FieldCount = 0; ... end; Which would indicate that if you add fields you only get the fields you added. I would like all the fields in the query AS WELL AS the ones I Add. Is this possible or do I have to add all the fields I'm using as well?

• Excel VBA to check autofilter for data

  - by cav719

  I need help checking for autofiltered rows not including the header. I want it to give a message box "No records found." then exit sub or continue with copy paste if there are rows beyond the header row. I know I need an If/Else entry after the filter to check for data but I'm having trouble figuring how to check. This code is being done from a UserForm I created. Here is my script: Private Sub Searchbycompanyfield_Click() If CompanyComboBox1.Value = "" Then MsgBox "Please enter a Company to begin search." Exit Sub End If ActiveSheet.Range("$A:$H").AutoFilter Field:=1, Criteria1:=EQDataEntry.CompanyComboBox1.Value, Operator:=xlOr Cells.Select Selection.Copy Sheets("Sheet2").Select Range("A5").Select ActiveSheet.Paste Call MessageBoxYesOrNoMsgBox End Sub Any help would be greatly appreciated.

• Stored Procedure with ALTER TABLE

  - by psayre23

  I have a need to sync auto_increment fields between two tables in different databases on the same MySQL server. The hope was to create a stored procedure where the permissions of the admin would let the web user run ALTER TABLE [db1].[table] AUTO_INCREMENT = [num]; without giving it permissions (That just smells of SQL injection). My problem is I'm receiving errors when creating the store procedure. Is this something that is not allowed by MySQL? DROP PROCEDURE IF EXISTS sync_auto_increment; CREATE PROCEDURE set_auto_increment (tableName VARCHAR(64), inc INT) BEGIN ALTER TABLE tableName AUTO_INCREMENT = inc; END;

• How can you tell the source of the data when using the Stream.BeginRead Method?

  - by xarzu

  When using the Stream.BeginRead Method, and you are reading from a stream into a memory, how is it determined where you are reading the data from? See: http://msdn.microsoft.com/en-us/library/system.io.stream.beginread.aspx In the list of parameters, I do not see one that tells where the data is being read from: Parameters buffer Type: System.Byte[] The buffer to read the data into. offset Type: System.Int32 The byte offset in buffer at which to begin writing data read from the stream. count Type: System.Int32 The maximum number of bytes to read. callback Type: System.AsyncCallback An optional asynchronous callback, to be called when the read is complete. state Type: System.Object A user-provided object that distinguishes this particular asynchronous read request from other requests.

• Pull image of rendered HTML from a specific browser

  - by Geo Ego

  I am working on an app that will be able to pull an image of rendered HTML from a specific browser. I would like the user to be able to select a specific browser to render an HTML file in, and capture the rendered output in an image file. I am starting with IE8, and I'm not sure where to begin to get the actual rendered output. I can easily open the file in that browser with Process.Start(), but I don't know how to return the rendered output. I have looked a little bit at sinking events, but I don't understand how that works or if that's the right way to go. I would just like some direction, and perhaps some resources to send me on the right path.

• SSIS Handling Extenal Issues

  - by durilai

  I have an SSIS package that works fine. The package runs every night and takes about 4 hours to complete. I have am a newb to SSIS, so I want to see what my options are. I am not finding anything on the web about these two issues, so any advice is greatly appreciated. What to do when I have an external issue such as a power failure/accidental restart. Is there a way to alert someone or have the package begin again on restart. A couple weeks ago there was a process that got hung and locked table, making the process not execute. How is the best way to handle ensuring I have the proper access before starting and if not, get the access. I am ok with killing the processes etc. Looking for best practice info. Thanks

• Why does my UIScrollView change it's original content offset when I scroll?

  - by Tony

  Before I scroll, my UIScrollView is laid out perfectly. See here However if I scroll up, the view bounces as I go out of bounds and then resets too high. See here I am going to guess this has to do with a hack that I did earlier to get the view to originally show like in the first screen shot. For some reason, to get my view to look like the second screen shot, I do: [scrollView setContentOffset:CGPointMake(0,-50) animated:YES]; in viewDidLoad But if I set the content offset to 0,0 in viewDidLoad, I get something that looks like the second screen shot when the view loads. This doesn't make much sense to me because if the content offset is 0,0 I would think the content should begin in the upper right corner of the screen. Does anyone know what could be going on here? Thanks!

• java question: Is it a method?

  - by Stefan

  Hello, I'm no Java guy, so I ask myself what this means: public Button(Light light) { this.light = light; } Is Button a method? I ask myself, because it takes an input parameter light. But if it was a method, why would it begin with a capital letter and has no return data type? Here comes the full example: public class Button { private Light light; public Button(Light light) { this.light = light; } public void press() { light.turnOn(); } } I know, this question is really trivial. However, I have nothing to do with Java and haven't found a description for the Button thing above. I'm just interested.

• log4j: Change format of loggers configured in another library.

  - by Ignacio Thayer

  Using clojure, I've been able to successfully setup log4j very simply by using this log4j.properties file, and including log4j in my classpath. # BEGIN log4j.properties log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout log4j.appender.STDOUT.layout.ConversionPattern=%d{MMdd HHmmss SSS} %5p %c [%t] %m\n log4j.rootLogger=DEBUG, STDOUT Then after :use'ing clojure.contrib.logging, I'm able to print a statement with the desired formatting as expected like so: (info "About to print this") (debug "This is debug-level") My question is how to achieve a consistent formatting for logging statements made from loggers configured in other libraries. I thought I could find existing loggers using org.apache.log4j.LogManager.getCurrentLoggers() and change the PatternLayouts there, but I'm not able to iterate over that enumeration in clojure, as I get the following error: Dont know how to create ISeq from: java.util.Vector$1 I assume this is possible somehow, and probably very simply. How? Thanks much.

• Linq to SQL EntitySet Records causing duplicate insertion

  - by Savvas Sopiadis

  In a WPF application i'm using Linq to SQL in a multi tier application. (This is an archailogy photo filing application), so every excavation has its corresponding Pictures, thus a one-to-many relationship. This relationship is correctly created by SQLMetal (which i'm using to create the POCOs). So here is the situation i 'm having trouble with: Saving changes (either of new or altered objects) is done through UnitOfWork() pattern this way: using (IUnitOfWork unitOfWork = UnitOfWork.Begin()) { //if this is a new record if (SelectedExcavation.excavation.ExcavationId == 0) { IsNewRecord = true; excavService.Add(SelectedExcavation.excavation); } //send the actual changes to the dbms unitOfWork.Commit(); } Everything works fine! BUTTTT!!! Whenever a record gets updated which has (already at least one ) corresponding Picture Record: 1) a new Excavation Record is inserted 2) the current Excavation Record gets updated 3) the previous Picture Record gets its Id changed to the newly created ExcavationId What is going on under the hood? Does Linq to SQL not handle such simple update scenarios? Thanks in advance

• Text box added using javascript doesnot respond as expected to the js attached to it.

  - by Mallika Iyer

  Hello, I am adding a text box using javascript: This is what is generated: <dd id="text3-element" style="width: 350px;"> <input type="text" size="50" id="text3" name="text3" onblur="return getFieldValue(this.id);" value=""> </dd> This is what is present in the getFieldValue function: function getFieldValue(id){ var elem = document.getElementById(id); alert(elem.value); return false; } I'm trying to get the value of the field added using javascript when the value of the filed changes. However, I keep getting the value as 'undefined', in spite of entering text into the newly added text box. This does not happen if the form already has a text box to begin with - i.e., if a text box is not being added via a js function. Anything missing / look wrong here? Thanks!

• I want to create an Android App that checks a website like Woot

  - by tim

  Im new to android and thought it would be fun to develop an app that goes out and checks woot.com. The idea I came up with is for the app to be a widget that refresh woot.com once a day and displays a picture of the item and price. If the widget is clicked on it would open the browser to woot.com. In theory this seems like it would be easy but Im having trouble figuring out where to begin. Any help would be appreciated. Thanks Tim

• Can I get a PTypeInfo from a string?

  - by Mason Wheeler

  This is probably going to be a "no", but is there any way I can use Delphi's RTTI, either old-school or the 2010 extended RTTI, to pass in a string containing the name of a type, specifically the name of an enumerated type, and have it give me the PTypeInfo for that type? I've looked through RTTI.pas and TypInfo.pas and I don't see any function that would do that, but I might have missed something. What I'm looking for: var info: PTypeInfo; begin info := GetTypeInfoFromName('TComponentStyle'); end; Or something like that. Thing is, the name of the enumerated type would be passed in; it wouldn't be known at compile time.

• Conseqences of assigning self

  - by Vegar

  Hi, Found a piece of code today, that I find a little smelly... TMyObject.LoadFromFile(const filename: String); begin if fileExists(filename) then self := TSomeObjectStreamer.ReadObjectFromFile(filename); end; If this code works, it will atleast leak some memory, but does it work? Is OK to assign to self in this manner? What if the streamed object is of a different subclass then the original self? What if the streamed object is of a different class with no common ancestore to the original self?

• DotNetOpenAuth: Webforms, Getting Started

  - by CccTrash

  I am trying to figure out how to get DotNetOpenAuth(http://www.dotnetopenauth.net/) working in my webforms app I don't understand where to begin. I have an OpenIDSelector on my Login.aspx that lets you choose google or Yahoo. You can choose one, then a popup comes up, and lets you login. Once you login the program hangs because it is trying to do something with a database??? Can't I just use some control(like the OpenIDSelector) and get back that the user was authenticated, get their ClaimedID and handle the rest myself? EDIT: Trying to get started with OpenID in Webforms? Go Here... http://www.dotnetopenauth.net/developers/code-snippets/programmatic-openid-relying-party/

• Fermat factorization method limit

  - by Fakrudeen

  I am trying to implement Fermat's factorization [Algorithm C in Art of computer programming Vol. 2]. Unfortunately in my edition [ISBN 81-7758-335-2], this algorithm is printed incorrectly. what should be the condition on factor-inner loop below? I am running the loop till y <= n [passed in as limit]. (if (< limit y) 0 (factor-inner x (+ y 2) (- r y) limit)) Is there anyway to avoid this condition altogether, as it will double the speed of loop? (define (factor n) (let ( ( square-root (inexact->exact (floor (sqrt n))) ) ) (factor-inner (+ (* 2 square-root) 1) 1 (- (* square-root square-root) n) n) ) ) (define (factor-inner x y r limit) (if (= r 0) (/ (- x y) 2) (begin (display x)(display " ")(display y)(display " ")(display r)(newline) ;(sleep-current-thread 1) (if (< r 0) (factor-inner (+ x 2) y (+ r x) limit) (if (< limit y) 0 (factor-inner x (+ y 2) (- r y) limit)) ) ) ) )
