  • What’s wrong with this code

    - by Arlen Beiler
    I get this error for the code below, what does it mean? [Fri Apr 23 10:57:42 2010] [error] [client 10.0.0.1] PHP Fatal error: Cannot re-assign $this in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\abp\fol\test.php on line 27, referer: http://abp.bhc.com/fol/ <?php $voiceboxes = array( '141133' => array( 'title' => 'Title', '1' => array( 'Title' => 'Title2', 'Link' => 'http://...', ), '12' => array( 'Title' => 'Title3', 'Link' => 'http://...', ) ), '1070453' => array( 'title' => 'Title4', '1' => array( 'Title' => 'Title5', 'Link' => 'http://...', ) ) ); $last = 0; //$this = 0; echo "<ol>\n"; foreach ($voiceboxes as $key => $value) { $last = 0; $this = null; //Error is thrown here, Line 27 //$voiceboxes[$key]['title'] echo "<ol>\n"; foreach ($value as $key2 => $value2) { if ($key2 == 'title') { echo "<li>$value2</li>\n"; } else { $this = (int) $key2; if ($this == $last + 1) { echo '<li>'; } else { '<li value="' . $key2 .

  • Query Months help

    - by StealthRT
    Hey all i am in need of some helpful tips/advice on how to go about my problem. I have a database that houses a "signup" table. The date for this table is formated as such: 2010-04-03 00:00:00 Now suppose i have 10 records in this database: 2010-04-03 00:00:00 2010-01-01 00:00:00 2010-06-22 00:00:00 2010-02-08 00:00:00 2010-02-05 00:00:00 2010-03-08 00:00:00 2010-09-29 00:00:00 2010-11-16 00:00:00 2010-04-09 00:00:00 2010-05-21 00:00:00 And i wanted to get each months total registers... so following the example above: Jan = 1 Feb = 2 Mar = 1 Apr = 2 May = 1 Jun = 1 Jul = 0 Aug = 0 Sep = 1 Oct = 0 Nov = 1 Dec = 0 Now how can i use a query to do that but not have to use a query like: WHERE left(date, 7) = '2010-01' and keep doing that 12 times? I would like it to be a single query call and just have it place the months visits into a array like so: do until EOF theMonthArray[0] = "total for jan" theMonthArray[1] = "total for feb" theMonthArray[2] = "total for mar" theMonthArray[3] = "total for apr" ...etc loop I just can not think of a way to do that other than the example i posted with the 12 query called-one for each month. This is my query as of right now. Again, this only populates for one month where i am trying to populate all 12 months all at once. SELECT count(idNumber) as numVisits, theAccount, signUpDate, theActive from userinfo WHERE theActive = 'YES' AND idNumber = '0203' AND theAccount = 'SUB' AND left(signUpDate, 7) = '2010-04' GROUP BY idNumber ORDER BY numVisits; The example query above outputs this: numVisits | theAccount | signUpDate | theActive 2 SUB 2010-04-16 00:00:00 YES Which is correct because i have 2 records within the month of April. But again, i am trying to do all 12 months at one time (in a single query) so i do not tax the database server as much when compared to doing 12 different query's... UPDATE I'm looking to do something like along these lines: if NOT rst.EOF if left(rst("signUpDate"), 7) = "2010-01" then theMonthArray[0] = rst("numVisits") end if if left(rst("signUpDate"), 7) = "2010-02" then theMonthArray[1] = rst("numVisits") end if etc etc.... end if Any help would be great! :) David

  • SDL_image/C++ OpenGL Program: IMG_Load() produces fuzzy images

    - by Kami
    I'm trying to load an image file and use it as a texture for a cube. I'm using SDL_image to do that. I used this image because I've found it in various file formats (tga, tif, jpg, png, bmp) The code : SDL_Surface * texture; //load an image to an SDL surface (i.e. a buffer) texture = IMG_Load("/Users/Foo/Code/xcode/test/lena.bmp"); if(texture == NULL){ printf("bad image\n"); exit(1); } //create an OpenGL texture object glGenTextures(1, &textureObjOpenGLlogo); //select the texture object you need glBindTexture(GL_TEXTURE_2D, textureObjOpenGLlogo); //define the parameters of that texture object //how the texture should wrap in s direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); //how the texture should wrap in t direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); //how the texture lookup should be interpolated when the face is smaller than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); //how the texture lookup should be interpolated when the face is bigger than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //send the texture image to the graphic card glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture->w, texture->h, 0, GL_RGB, GL_UNSIGNED_BYTE, texture-> pixels); //clean the SDL surface SDL_FreeSurface(texture); The code compiles without errors or warnings ! I've tired all the files formats but this always produces that ugly result : I'm using : SDL_image 1.2.9 & SDL 1.2.14 with XCode 3.2 under 10.6.2 Does anyone knows how to fix this ?

  • Issues in Convergence of Sequential minimal optimization for SVM

    - by Amol Joshi
    I have been working on Support Vector Machine for about 2 months now. I have coded SVM myself and for the optimization problem of SVM, I have used Sequential Minimal Optimization(SMO) by Mr. John Platt. Right now I am in the phase where I am going to grid search to find optimal C value for my dataset. ( Please find details of my project application and dataset details here http://stackoverflow.com/questions/2284059/svm-classification-minimum-number-of-input-sets-for-each-class) I have successfully checked my custom implemented SVM`s accuracy for C values ranging from 2^0 to 2^6. But now I am having some issues regarding the convergence of the SMO for C 128. Like I have tried to find the alpha values for C=128 and it is taking long time before it actually converges and successfully gives alpha values. Time taken for the SMO to converge is about 5 hours for C=100. This huge I think ( because SMO is supposed to be fast. ) though I`m getting good accuracy? I am screwed right not because I can not test the accuracy for higher values of C. I am actually displaying number of alphas changed in every pass of SMO and getting 10, 13, 8... alphas changing continuously. The KKT conditions assures convergence so what is so weird happening here? Please note that my implementation is working fine for C<=100 with good accuracy though the execution time is long. Please give me inputs on this issue. Thank You and Cheers.

  • Troubleshooting a COM+ application deadlock

    - by Chris Karcher
    I'm trying to troubleshoot a COM+ application that deadlocks intermittently. The last time it locked up, I was able to take a usermode dump of the dllhost process and analyze it using WinDbg. After inspecting all the threads and locks, it all boils down to a critical section owned by this thread: ChildEBP RetAddr Args to Child 0deefd00 7c822114 77e6bb08 000004d4 00000000 ntdll!KiFastSystemCallRet 0deefd04 77e6bb08 000004d4 00000000 0deefd48 ntdll!ZwWaitForSingleObject+0xc 0deefd74 77e6ba72 000004d4 00002710 00000000 kernel32!WaitForSingleObjectEx+0xac 0deefd88 75bb22b9 000004d4 00002710 00000000 kernel32!WaitForSingleObject+0x12 0deeffb8 77e660b9 000a5cc0 00000000 00000000 comsvcs!PingThread+0xf6 0deeffec 00000000 75bb21f1 000a5cc0 00000000 kernel32!BaseThreadStart+0x34 The object it's waiting on is an event: 0:016> !handle 4d4 f Handle 000004d4 Type Event Attributes 0 GrantedAccess 0x1f0003: Delete,ReadControl,WriteDac,WriteOwner,Synch QueryState,ModifyState HandleCount 2 PointerCount 4 Name <none> No object specific information available As far as I can tell, the event never gets signaled, causing the thread to hang and hold up several other threads in the process. Does anyone have any suggestions for next steps in figuring out what's going on? Now, seeing as the method is called PingThread, is it possible that it's trying to ping another thread in the process that's already deadlocked? UPDATE This actually turned out to be a bug in the Oracle 10.2.0.1 client. Although, I'm still interested in ideas on how I could have figured this out without finding the bug in Oracle's bug database.

  • How could I make this display for listbox?

    - by baron
    Hello everyone, I have a databound listbox which is actually displaying two columns of data. It is displayed as follows: <UserControl.Resources> <DataTemplate x:Key="AlignedPairs"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="10" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <TextBlock Text="{Binding Fruits}" Grid.Column="0" /> <TextBlock Text="->" TextAlignment="Center" Grid.Column="1" /> <TextBlock Text="{Binding Colors}" Grid.Column="3" /> </Grid> </DataTemplate> </UserControl.Resources> <ListBox Name="lbStuff" Grid.ColumnSpan="2" Grid.Row="1" ItemTemplate="{StaticResource AlignedPairs}"> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalContentAlignment" Value="Stretch" /> </Style> </ListBox.ItemContainerStyle> </ListBox> Then Itemsource set in codebehind. Based on some logic however, I would like to set either a line or a item in one of the columns, e.g. a fruit to red, or the line to bold. I have code to work out which Fruit or Color I would like to differentiate (by color/bold) in the code behind, but I can't figure out, especially given the custom listbox display, how I could go about setting a particular item to a different color/bold. Does anyone have any ideas? Let me know if any further code is required. Cheers.

  • FileReference.load() does not as excepted

    - by Yang Bo
    I used Flash player 10, and Flex SDK 3.4. The code as followings: // Following comes callbacks function imageLoadOpenCallback(evt:Event):void { trace("in--open"); } function imageLoadCompleteCallback(evt:Event):void { trace("in--load"); var fr:FileReference = evt.target as FileReference; trace(fr.data); } function imageLoadErrorCallback(evt:IOErrorEvent):void { trace("in--ioerror"); } function imageSelectCancelCallback(evt:Event):void { trace("in cancel"); } function imageSelectCallback(evt:Event):void { trace("in -- select"); for (var i:int=0; i<frl.fileList.length; i++) { frl.fileList[i].addEventListener(Event.OPEN, imageLoadOpenCallback); frl.fileList[i].addEventListener(Event.COMPLETE, imageLoadCompleteCallback); frl.fileList[i].addEventListener(IOErrorEvent.IO_ERROR, imageLoadErrorCallback); frl.fileList[i].load(); trace(frl.fileList[i]); trace(frl.fileList[i].creationDate); trace(frl.fileList[i].creator); trace(frl.fileList[i].data); trace(frl.fileList[i].name); } } // Following comes UI handlers function onAddPictures():void { var imageFilter:FileFilter = new FileFilter("Images", "*.jpg;*.png"); frl.addEventListener(Event.SELECT, imageSelectCallback); frl.addEventListener(Event.CANCEL, imageSelectCancelCallback); frl.browse([imageFilter]); } Only the imageSelectCancelCallback handler get called when I select some files in the dialog. But no load/open/io_error handler get called at all. I have Google some code example, in which it used FileReference instead of FileReferenceList. I don't know the reason, could you please help me?

  • XML RPC c# Call returns array of strings and int

    - by chillconsulting
    I'm doing an XML RPC call in ASP.net with c# and the call returns an Array called userinfo with strings and integers in it and I can't seem to figure out how to parse the data and put it into string and int objects... The only thing that compiles is if I make it an Object in the struct. The int returns fines and is referenced easily. Any help would be appreciated - this is what I got. public Page_Load(object sender, EventArgs e){ IValidateSSO proxy = XmlRpcProxyGen.Create<IValidateSSO>(); UserInfoSSOValue ret2 = proxy.UserInfoSSO(ssoAuth, ssoValue); int i = ret2.isonid; } public struct UserInfoSSOValue { public Object userinfo; public int isonid; } [XmlRpcUrl("host")] public interface IValidateSSO : IXmlRpcProxy { [XmlRpcMethod("sso.session_userinfo")] UserInfoSSOValue UserInfoSSO(string ssoauth, string sid); } Here is what the xml rpc calls returns (I know it's in php... I'm trying to implement in c#): sso.session_userinfo(string $ssoauth, string $sid) string $ssoauth - authentication string (assigned by ONID support) string $sid - sid to get info on Returns: Array ( [userinfo] => Array ( [lastname] => College [expire_time] => 1118688011 [osuuid] => 12345678901 [sid_length] => 3600 [ip] => 10.0.0.1 [sid] => WiT7ppAEUKS3rJ2lNz3Ue64sGPxnnLL0 [username] => collegej [firstname] => Joe [fullname] => College, Joe Student [email] => [email protected] [create_time] => 1118684410 ) [isonid] => 1 ) array userinfo - array containing basic user information

  • How to write text(using CGContextShowTextAtPoint) dynamically near graph x and y-axis intervals?

  • How to map IDictionary<string, object> in Fluent NHibernate?

    - by user298221
    I am looking to persist user preferences into a collection of name value pairs, where the value may be an int, bool, or string. There are a few ways to skin this cat, but the most convenient method I can think of is something like this: public class User { public virtual IDictionary<string, object> Preferences { get; set; } } with its usage as: user.Preferences["preference1"] = "some value"; user.Preferences["preference2"] = 10; user.Preferences["preference3"] = true; var pref = (int)user.Preferences["preference2"]; I'm not sure how to map this in Fluent NHibernate, though I do think it is possible. Generally, you would map a simpler Dictionary<string, string> as: HasMany(x => x.Preferences) .Table("Preferences") .AsMap("preferenceName") .Element("preferenceValue"); But with a type of 'object', NHibernate doesn't know how to deal with it. I imagine a custom UserType could be created that breaks an 'object' down to a string representing its Type and a string representing the value. We would have a table that looks kind of like this: Table Preferences userId (int) preferenceName (varchar) preferenceValue (varchar) preferenceValueType (varchar) and the hibernate mapping would like this: <map name="Preferences" table="Preferences"> <key column="userId"></key> <index column="preferenceName" type="String" /> <element type="ObjectAsStringUserType, Assembly"> <column name="preferenceValue" /> <column name="preferenceValueType"/> </element> </map> I'm not sure how you would map this in Fluent NHibernate. Maybe there's a better way to do this, or maybe I should just suck it up and use IDictionary<string, string>. Any ideas?

  • How does lucene index documents?

    - by Mehdi Amrollahi
    Hello, I read some document about Lucene; also I read the document in this link (http://lucene.sourceforge.net/talks/pisa). I don't really understand how Lucene indexes documents and don't understand which algorithms Lucene uses for indexing? On the above link, it says Lucene uses this algorithm for indexing: incremental algorithm: maintain a stack of segment indices create index for each incoming document push new indexes onto the stack let b=10 be the merge factor; M=8 for (size = 1; size < M; size *= b) { if (there are b indexes with size docs on top of the stack) { pop them off the stack; merge them into a single index; push the merged index onto the stack; } else { break; } } How does this algorithm provide optimized indexing? Does Lucene use B-tree algorithm or any other algorithm like that for indexing - or does it have a particular algorithm? Thank you for reading my post.

  • Incorrect rendering in dojox charting stacked column?

    - by FokeyJoe
    Hiya, I seem to be having a problem with my dojo stackedcolumn whereby the scale of some of the bars is correct for some x-axis points, but not others.

    i just loved the fullcalendar and wanted to implement it in a small application, everythin worked OK. i am able to get the events from my database through json to the front end. but all events are being listed as "ALL-DAY" events itself. not able to figure out why.. here is the screenshot for the same. any ideas what is going wrong..? i am using asp.net and c#. i have already tried sending the start and end dates in the ToString(), ToShortDateString(), ToString("s"), ToLongDateString(), ToUniversalTime(). nothing seems to working for me at the moment. i tried hard coding and sendin the data too. sample json of my data [{ "id": "2", "title": "Event2", "start": "1274171700", "end": "1274175600" }, { "id": "1", "title": "Event1", "start": "5/18/2010 16:30:00", "end": "5/18/2010 19:30:00" }, { "id": "3", "title": "Event3", "start": "5/18/2010 2:05:00 PM", "end": "5/18/2010 3:10:00 PM" }, { "id": "4", "title": "Event4", "start": "5/18/2010", "end": "5/18/2010" }, { "id": "5", "title": "Event5", "start": "2010-05-18T14:05:00", "end": "2010-05-18T15:10:00" }] all data above has different formats of dates, and at the moment nothing seems to be working. fullcalender accepts the day part fine, but not the time part. not sure why. can anybody help?

  • Working around MySQL error "Deadlock found when trying to get lock; try restarting transaction"

    - by Anon Guy
    Hi all: I have a MySQL table with about 5,000,000 rows that are being constantly updated in small ways by parallel Perl processes connecting via DBI. The table has about 10 columns and several indexes. One fairly common operation gives rise to the following error sometimes: DBD::mysql::st execute failed: Deadlock found when trying to get lock; try restarting transaction at Db.pm line 276. The SQL statement that triggers the error is something like this: UPDATE file_table SET a_lock = 'process-1234' WHERE param1 = 'X' AND param2 = 'Y' AND param3 = 'Z' LIMIT 47 The error is triggered only sometimes. I'd estimate in 1% of calls or less. However, it never happened with a small table and has become more common as the database has grown. Note that I am using the a_lock field in file_table to ensure that the four near-identical processes I am running do not try and work on the same row. The limit is designed to break their work into small chunks. I haven't done much tuning on MySQL or DBD::mysql. MySQL is a standard Solaris deployment, and the database connection is set up as follows: my $dsn = "DBI:mysql:database=" . $DbConfig::database . ";host=${DbConfig::hostname};port=${DbConfig::port}"; my $dbh = DBI->connect($dsn, $DbConfig::username, $DbConfig::password, { RaiseError => 1, AutoCommit => 1 }) or die $DBI::errstr; I have seen online that several other people have reported similar errors and that this may be a genuine deadlock situation. I have two questions: What exactly about my situation is causing the error above? Is there a simple way to work around it or lessen its frequency? For example, how exactly do I go about "restarting transaction at Db.pm line 276"? Thanks in advance.

To put space after each letter in such word. Then it is necessary to conclude this word in a tag with a class "spaced". The word is considered "long" if the quantity of letters in this word is more 10 (for example. It is possible to set any value). How to solve this problem means xslt?

  • Why can't I debug from Visual Studio 2005 after installing IE8?

    - by tjrobinson
    I've just installed IE8 (final) and restarted. I can no longer debug Web Application Projects using Visual Studio 2005 on Windows Server 2003 Enterprise R2. I get the message "Internet Explorer cannot display the webpage" and then WebDev.WebServer.exe quits with no visible error message and nothing in the Event Viewer. Does anyone have any ideas? Things that haven't helped: Adding localhost to trusted sites Changing the port to 8080 or 80 Checking my hosts file (it's just got 127.0.0.1 localhost in it) Things that have helped a bit: Running (not debugging) with CTRL-F5, which works fine (unless you need to debug) Changing the default Visual Studio browser to Firefox, which allows me to debug My hosts file contains: # Copyright (c) 1993-1999 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost

  • FasterCSV Parsing issue?

    - by Schroedinger
    G'day guys, I'm currently using fastercsv to construct ActiveRecord elements and I can't for the life of me see this bug (tired), but for some reason when it creates, if in the rake file i output the column I want to save as the element value, it puts out correctly, as either a Trade or a Quote but when I try to save it into the activerecord, it won't work. FasterCSV.foreach("input.csv", :headers => true) do |row| d = DateTime.parse(row[1]+" "+row[2]) offset = Rational(row[3].to_i,24) o = d.new_offset(offset) t = Trade.create( :name => row[0], :type => row[4], :time => o, :price => row[6].to_f, :volume => row[7].to_i, :bidprice => row[10].to_f, :bidsize => row[11].to_i, :askprice => row[14].to_f, :asksize => row[15].to_i ) end Ideas? Name and Type are both strings, every other value works except for type. Have I missed something really simple?

  • SIGABRT error when running MonoTouch application

    - by hambonious
    I'm new to MonoTouch and 9 times out of 10, when I try to run my MonoTouch app on the iPhone simulator (debug mode and regular), I receive a long error output that begins with the following message: Error connecting stdout and stderr (127.0.0.1:10001) Couldn't register com.yourcompany.[appnamehere] with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger.Stacktrace: at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at MonoTouch.UIKit.UIApplication.Main (string[],string,string) <0x00089 at MonoTouch.UIKit.UIApplication.Main (string[]) <0x00014 at PodcastManager.Application.Main (string[]) <0x00010 at (wrapper runtime-invoke) .runtime_invoke_void_object (object,intptr,intptr,intptr) <0x00043 And ends with: ================================================================= Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= The weird thing is it will work some of the time. Once, a reboot of my machine did it. Others, just restarting MonoDevelop and/or the simulator. I can provide the entire error output if you think that may help. Any ideas?

  • Bitwise Interval Arithmetic

    - by KennyTM
    I've recently read an interesting thread on the D newsgroup, which basically asks, Given two signed integers a ∈ [amin, amax], b ∈ [bmin, bmax], what is the tightest interval of a | b? I'm think if interval arithmetics can be applied on general bitwise operators (assuming infinite bits). The bitwise-NOT and shifts are trivial since they just corresponds to -1 − x and 2n x. But bitwise-AND/OR are a lot trickier, due to the mix of bitwise and arithmetic properties. Is there a polynomial-time algorithm to compute the intervals of bitwise-AND/OR? Note: Assume all bitwise operations run in linear time (of number of bits), and test/set a bit is constant time. The brute-force algorithm runs in exponential time. Because ~(a | b) = ~a & ~b and a ^ b = (a | b) & ~(a & b), solving the bitwise-AND and -NOT problem implies bitwise-OR and -XOR are done. Although the content of that thread suggests min{a | b} = max(amin, bmin), it is not the tightest bound. Just consider [2, 3] | [8, 9] = [10, 11].)

  • JACOB (Java/COM/ActiveX) - How to troubleshoot event handling?

    - by Youval Bronicki
    I'm trying to use JACOB to interact with a COM object. I was able to invoke an initialization method on the object (and to get its properties), but am not getting any events back. The code is quoted below. I have a sample HTML+Javascript page (running in IE) that successfully receives events from the same object. I'm considering the following options, but would appreciate any concrete troubleshooting ideas ... Send my Java program to the team who developed the COM object, and have them look for anything suspicious on their side (does the object have a way on knowing whether there's a client listening to its events, and whether they were successfully delivered?) Get into the native parts of JACOB and try to debug on that side. That's a little scary given that my C++ is rusty and that I've never programmed for Windows. public static void main(String[] args) { try { ActiveXComponent c = new ActiveXComponent( "CLSID:{********-****-****-****-************}"); // My object's clsid if (c != null) { System.out.println("Version:"+c.getProperty("Version")); InvocationProxy proxy = new InvocationProxy() { @Override public Variant invoke(String methodName, Variant[] targetParameters) { System.out.println("*** Event ***: " + methodName); return null; } }; DispatchEvents de = new DispatchEvents((Dispatch) c.getObject(), proxy); c.invoke("Init", new Variant[] { new Variant(10), //param1 new Variant(2), //param2 }); System.out.println("Wating for events ..."); Thread.sleep(60000); // 60 seconds is long enough System.out.println("Cleaning up ..."); c.safeRelease(); } } catch (Exception e) { e.printStackTrace(); } finally { ComThread.Release(); } }

    Hello, I have been told that I should add a sidebar to one page of this .net project, but the master page don't include a sidebar. How can I add a sidebar to one page only ? This is the code for the Master Template, can anyone suggest or help me out here?
