• Do sfSubForm.fForm.RecordSource and Forms(fForm).RecordSource refer to the same object and property?

  - by Raymond Rosalind

  Hi, this has me pretty confused and I can't find the answer anywhere else so thought I'd post here to see if anyone can help! I have a form in an Access 2007 database with a subform (sfSubform) embedded in it. The subform control's SourceObject is set to be another form (fForm). fForm's RecordSource starts out as a table. At one point I want to change the data displayed in the subform to the result of a SQL statement, so I use sfSubform.Form.RecordSource = strSQL. This works fine. However, if I ouput the name of the RecordSource for fForm after making this change, it still gives the name of the table that I orginially set. Does sfSubform.Form.RecordSource not change the source of fForm? Is it a copy of fForm that is embedded in the control? Hope all that makes sense.

• xsl:variable xsl:copy-of select

  - by user1901345

  I have the following XML: Picture 1 Picture 2 Picture 3 While this XSL does what is expected (output the attr of the first picture): It seems to be not possible to do the same inside the variable declaration using xsl:copy-of: Curious: If I just select "$FirstPicture" instead of "$FirstPicture/@attr" in the second example, it outputs the text node of Picture 1 as expected... Before you all suggest me to rewrite the code: This is just a simplified test, my real aim is to use a named template to select a node into the variable FirstPicture and reuse it for further selections. I hope someone could help me to understand the behavior or could suggest me a proper way to select a node with code which could be easily reused (the decission which node is the first one is complex in my real application). Thanks.

• password limitations in SQL Server and MySql

  - by asteroid

  Does MySql 5.1 and SQL Server 2008 (Web edition, Standard) have any functional password limitations other than length limits? Are metacharacters in any form a bad idea to use, like bang, pipe, hash, any slash, carrot, and so on? I know that MySql 5.1 has a password length limitation of 16 characters that is hardcoded, but I was wondering, are any metacharacters (i.e. non alphanumerics) a bad idea to use? And is this true in SQL Server 2008 Web edition, Standard? So specifically: can symbols like: /`~:}{[]^ be used successfully? I would hope it doesn't matter to the database, but I don't understand enough about password storage in enterprise database systems yet to know for sure, and I was looking for confirmation or an explanation.

• iqueryable select/where not working

  - by Steve

  I have two tables Boxer and Prospect. Boxers has general stuff like name and and dob etc and a BoxerId While Prospect contains only one value (at the moment) which is a boxerId. If a boxer is a prospect(up and coming boxer) there Id will be in the prospect table. This works fine but now I want to select all boxers that are prospects public static IQueryable<Boxer> IsProspect(this IQueryable<Boxer> query) { //this does not filter down to only prospects!!! return query.Where(x => x.Prospect != null); } This is the function I call using: var repository = GetRepository<Boxer>(); var boxers = repository.Query().IsProspect(); I would hope this would filter my collection of all boxers down to just boxers that are prospects! Oddly it doesnt filter it but if i hover over my boxers object and look at each boxer during debugging I can see "IsProspect" true or false correctly

• How to create a snapshot or clone of PHP, MySQL page... Inspiration needed

  - by jimbo

  Hi, We have a web application that creates a dynamic PHP page with all the MySQL stored details a user has entered via a number a forms. So far so good, but we want this information stored some how to be refereed to at a later date, as an administrator can make changes to the data, which reflects on calculations that are worked out from this saved data. When going back over this saved data we need to be able to see all the information submitted for that particular calculation, so if that data has changed we will see what is was relating to that calculation. Now we have thought about maybe a snapshot when the calculation is done, pdf of the webpage or something similar would do, but is this simple to do? I hope this makes sense...

• To use an api or store a large dataset in a rails app?

  - by Dave

  Hi all- I am working on a site that has the potential to need a LOT of space. Basically we hope to have every video game every created stored in a database along with an image of the cover. There are some api's out there that might be able to help, like GiantBomb's (www.giantbomb.com). We are trying to decide whether to store the data locally and if so where to find that comprehensive a list, or make calls to the api on demand. The problem with the latter is likely latency and also downtime problems. Assuming we want to store it locally here are the questions: 1) Where can we find this kind of data (yes, I looked on google, and no I couldnt find anything:)) 2) What is the most efficient way to encode and store the images? Thanks!

• Can't type anything in inputs or textareas

  - by dev reactive.by

  Hello, I have a problem: I've add a Jquery UI drag-n-drop widget to my page, but after that I can't type anything into inputs or textareas. I use jQuery 1.4.2 and jQuery UI 1.8rc3, and tiny_mce for convert textareas into WYSIWUG editor (I've tried to disable tiny_mce). When I put $("input").click( function(){ alert('clicked!'); }); - it's working(I have an alert). When I get focused to any input I even can't refresh page by F5 and go to the next element by Tab key. There's a page: http://cms.reactive.by/test.htm (click to clip2net.com/clip/m7787/1269022358-clip-3kb.png to see that jQuery UI is workong) And yes.. there's no errors in FireBug. I hope You can help me to understand what's wrong with this code.

• Targeting an iFrame once with jQuery

  - by user275074

  Hi, I have a series of frames (4) which are used in a page to create loading of dynamic content through Ajax calls. In each of these frames I target parent level elements and update them with there respective content e.g. $("#loadingGrid1",top.document).show(); $("#frameSkills",top.document).hide(); In jQuery is there a way to instead of targeting specific elements on the parent page multiple times, simply target the page once into a variable e.g. var parentPage=$('#frameSkills',top.document); And then use this variable to apply content like $(parentPage #loadingGrid1).hide() Hope I've explained what I'm after enough. Basically, I'm having to call "top.document" in every jQuery selector I make and it seems like a waste of energy.

• NSMutableArray of Objects misbehaves ...

  - by iFloh

  I hope someone understands what happens to my NSMutableArray. I read records a, b, c, d from a database, load the fields into an object an add the object to an array. To do this I read the records into an instance of that object (tmpEvent) and add the Object to the target array (NSMutableArray myArray). the code looks like: for (condition) { tmpEvent.field1 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 0)]; tmpEvent.field2 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 1)]; tmpEvent.field3 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 2)]; NSLog(@"myArray: adding %@", tmpEvent.field1); [myArray addObject:tmpEvent]; } The NSLog shows myArray: adding a myArray: adding b myArray: adding c myArray: adding d Subsequent I enumerate the array (this can be in the same or a different method): for (myObject *records in myArray) { NSLog(@"iEvents value %@", records.field1); } The NSLog now shows: myArray value d myArray value d myArray value d myArray value d a mystery .... ??? any thoughts?

• Is it possible to *optionally* override a theme in Drupal 6?

  - by David Semeria

  I want to override the theming of only one (custom) menu. I can do this with phptemplate_menu_tree() but - of course - it overrides the rendering of all menus. I've tried returning FALSE (an obvious technique IMO) if the menu is not the specific one I want to override - but this doesn't cause the overridden theme function to be called. My only alternative (when the menu is anything other than the specific one) is to call the overridden function from within phptemplate_menu_tree() - but this seems to defeat the whole point of the override system, since the default rendering function will be hard-coded therein. I hope the explanation is clear, and any help is greatly appreciated - tks.

• How to use .DefaultListCellRenderer

  - by loddn

  First, i'm new at Java-programming and my native lang is not english, but still i hope to get some help from you all. What I try to do is a simple java-interface with a jComboBox and a jList. I want to poplate to jComboBox with Object-names and when the user select one of the names get the object-id which i will use to populate the jList. It's probably simple but i have bin stuck with this problem all day. private void loadComboBox() { biz.Object object = new biz.Object(); try { ArrayList<biz.Object> arrayOfObjects= object.getAllObjects();// ArrayList of objects for (biz.Object o:arrayOfObjects) { if (o != null) cbm.addElement(o); //`toString-method } cb.setModel(cbm); //JComboBox

• MySQL UPDATE WHERE IN for each listed value separately?

  - by Tom

  Hi, I've got the following type of SQL: UPDATE photo AS f LEFT JOIN car AS c ON f.car_id=c.car_id SET f.photo_status=1 , c.photo_count=c.photo_count+1 WHERE f.photo_id IN ($ids) Basically, two tables (car & photo) are related. The list in $ids contains unique photo ids, such as (34, 87, 98, 12). With the query, I'm setting the status of each photo in that list to "1" in the photo table and simultaneously incrementing the photo count in the car table for the car at hand. It works but there's one snag: Because the list can contain multiple photo ids that relate to the same car, the photo count only ever gets incremented once. If the list had 10 photos associated with the same car, photo_count would become 1 .... whereas I'd like to increment it to 10. Is there a way to make the incrementation occur for each photo individually through the join, as opposed to MySQL overthinking it for me? I hope the above makes sense. Thanks.

• Anyone plotting SO via code_swarm?

  - by Tim Post

  Is anyone working on something to render individual questions, or SO as a whole with codeswarm? If so, can you post a link to your work that transforms SO questions into revisions that codeswarm can understand (i.e. svn?) It would be really, really cool to see SO played (as a whole) via codeswarm, so I hope to not only ask if anyone is working it, but see if anyone is interested in trying to accomplish it. Augmenting that, will database dumps be made available? EDIT: Database dumps have since been made available :) Enough with user voice, is anyone doing it? If so, what VCS did you mock?

• MovieClip progress bar width is too small relative to parent container

  - by egyedg

  I am new to ActionScripot and Flash and I am stuck with the following problem: On the stage I have a movieclip (Container, originally 200px width) and inside it with a progressbar movieclip (originally 700px width), scaled with Free Transform Tool to fit the parent container. The width of the container changes run-time while resizing the scene. In ActionScript I have a function which should set the progress bar width according to a calculated percentage value: private function updateProgress(event:TimerEvent):void { var barWidth:int = _container.width; var progress:Number = _stream.time / _stream.duration * barWidth; _progressBar.width = progress; } My problem is that the progressBar even at full time (100%) is only at 1/4 of the parent container. I assume that it comes from the symbols original size. Can I correct this programatically, or I must redesign it with the "designer"? I hope I made clear my problem, as I said, I'm new in Flash. Thanks in advance.

• Why a revert a file in EGit, but the dirty symbol '<' still exist in the project view?

  - by Happier

  I try EGit revert for several days, It's very confuse that when I revert the file following the user guide, and I still got the file dirty symbol in the related file. http://wiki.eclipse.org/EGit/User_Guide#Reverting_Changes I choose 'Replace with' - 'File in Git Index', it works, the content has been revert, but the symbol stays the same, sometimes, the symbol will disappear after a while, but sometimes, it didn't disappear. I'm using eclipse on windows, I'm not sure it's about the '\r\n' character. But I use 'Compare with ' - 'File in Git Index', two files look the same. Hope someone can tell me why, I think it can be a bug? Thank you in advance.

• How online-game clients are able to exchange data through internet so fast?

  - by Kirzilla

  Hello, Let's imagine really simple game... We have a labirinth and two players trying to find out exit in real time through internet. On every move game client should send player's coordinates to server and accept current coordinates of another client. How is it possible to make this exchange so fast (as all modern games do). Ok, we can use memcache or similar technology to reduce data mining operations on server side. We can also use fastest webserver etc., but we still will have problems with timings. So, the questions are... What protocol game clients are usually using for exchanging information with server? What server technologies are coming to solve this problem? What algorithms are applied for fighting with delays during game etc. PS: Sorry for my English and I hope that my question is clear. Thank you.

• Need help in translating code from C or C++ to Java.

  - by Vuntic

  From this article. Here's the code: float InvSqrt(float x){ // line 0 float xhalf = 0.5f * x; int i = *(int*)&x; // store floating-point bits in integer i = 0x5f3759d5 - (i >> 1); // initial guess for Newton's method x = *(float*)&i; // convert new bits into float x = x*(1.5f - xhalf*x*x); // One round of Newton's method return x; } ...I can't even tell if that's C or C++. Could someone translate it to Java for me, please? It's (only, I hope) lines 2 and 4 that are confusing me. I'll edit out the confusion about C/C++ from the tags once somebody tells me which it is.

• Can you write to a file (on a disk) in JavaScript?

  - by asdfqwer

  I don't wanna come across as a troll, so please excuse my question's demeanor, but I am a novice-intermediate programmer taking a stab at AJAX. While reading up on JavaScript I found it curious that most of the examples I've been drawing on use PHP for such an operation. I know many of you may argue that 'I'm doing it wrong' or 'JavaScript is a client-side language' etc. but the question stands. . .can you write a file in only JavaScript? EDIT: Sorry, just read faq, failed to mention this my first post on Stackoverflow while I hope I'm not sounding argumentative, pompous, or subjective.

• SP: Random Records, Fave Record, Plus Known Record, NO repetition.

  - by Munklefish

  Hi, Thanks to help from a lot of you guys ive been given the following code which works great. However ive realised ive missed an important bit of info out of the question and so have reposted here (with updated code) to clarify. The following code gets 5 random records from a table plus a further single record based on the users favourite as identified in a second table: CREATE PROCEDURE web.getRandomCharities ( @tmp_ID bigint --members ID ) AS BEGIN WITH q AS ( SELECT TOP 5 * FROM TBL_CHARITIES WHERE cha_Active = 'TRUE' AND cha_Key != '1' ORDER BY NEWID() ) SELECT * FROM q UNION ALL SELECT TOP 1 * FROM ( SELECT * FROM TBL_CHARITIES WHERE TBL_CHARITIES.cha_Key IN ( SELECT members_Favourite FROM TBL_MEMBERS WHERE members_Id = @tmp_ID ) EXCEPT SELECT * FROM q ) tc END However, i realised i also need to include the record where "cha_Key == '1'" if it isnt the same as the record returned in the second SELECT statement in the code shown above. HOpe that makes sense? THANKS!!!

• Hibernate HQL to basic SQL (no joins)

  - by CC

  Hello everybody, I working on a project with Hibernate and we need to replace Hibernate with some "home made persistence" stuff. The idea is that the project is big enough, and we have many HQL queries. The problem is with the queries like select a,b from table1, table2 on t1.table1=t2.table2 Basically all joins are not supported by our "hand made persistence" stuff. What I would need, is to be able to do some sort of transcoder, which will take as a input the HQL queries and output some SQL, but SQL without joins I hope you get the idea. My persistence layer does not supports joins. Does anybody has any idea about something like that? Some framework, or something? Thanks alot everybody. C.C.

• SQL - logical AND among multiple rows

  - by potrnd

  Hello, First of all sorry that I could not think of a more descriptive title. What I want to do is the following using only SQL: I have some lists of strings, list1, list2 and list3. I have a dataset that contains two interesting columns, A and B. Column A contains a TransactionID and column B contains an ItemID. Naturally, there can be multiple rows that share the same TransactionIDs. I need to catch those transactions that have at least one item ID that exists whithin each list (list1, list2 AND list3). I also need to count how many times does that happen for each transaction. I hope that makes enough sense, perhaps I will be able to explain it better with a clear head. Thanks in advance

• Strange macro declaration in C

  - by Andrey Atapin

  Exploring libusb-1.0.9 source code, I have found such line (./os/poll_windows.c:78): #define CHECK_INIT_POLLING do {if(!is_polling_set) init_polling();} while(0) As for me this is the same like: #define CHECK_INIT_POLLING if(!is_polling_set) init_polling(); Is there any reason to loop that expression? UPDATE: I couldn't still realize what'd be wrong after the answers, and the following example helped: #include <stdio.h> #define TEST if(test) foo(); #define TEST_DO do { if(test) foo(); } while(0) int test = 1; void foo() { printf("%s", "Foo called"); } int main(int argc, char** argv) { if(argc > 1) TEST_DO; /* LINE 12 */ else printf("%s", "skipping..."); return 0; } If you put TEST at line 12, a compiler will give an error "error: ‘else’ without a previous ‘if’". Hope, this will help someone.
