  • keep image inside a frame

    - by Mick
    Hi can anyone help me with a problem please. I am not looking for anybody to write code for me but just give me a few pointers. I want to to put a frame or border around an image in actionscript3. I want to use an image that is considerably bigger than the border. the effect would be that the image would move around but only show what is inside the border. similar to looking through a keyhole ?? my best effort was to do a reverse mask, where the mask did not move but without success. If anyone has any idea's I would be very grateful Thanks

  • Default program not choosing on Windows 7

    - by Trollolz
    this is my first time posting and i need some help. I have a file named .kv6 format. I used slab6 (the correct and only program) to edit this file. I had it chosen as default program to open it upon double click. But today it stopped using that and reset to an unknown file. So I tried to set it again and when I hit "Browse" and select slab6 again it acts like it chooses it but doesn't actually show up as the default program or Other Programs. I can choose whatever other program and it will show up as a new Default Program but won't work to open it =\ Any help you be appreciated, thanks.

  • Network location is not on the Domain

    - by Kyle Brandt
    I have a computer joined to the domain, but it doesn't view the network "location" as being part of the domain. I have tried removing and rejoining the domain and this doesn't help: Other computers in the same network don't have this problem. I have also tried several different icons, including both the train and the airplane which doesn't seem to make a difference. At least using nslookup, the server seems to have connectivity with the DCs in the same site. There also seem to be some errors that suggest a NULL domain: Computer: OR-WEB05.ds.stackexchange.com Description: NtpClient was unable to set a domain peer to use as a time source because of failure in establishing a trust relationship between this computer and the '' domain in order to securely synchronize time. NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: The trust relationship between this workstation and the primary domain failed. (0x800706FD)

  • Data structure name: combination array/linked list

    - by me_and
    I have come up with a data structure that combines some of the advantages of linked lists with some of the advantages of fixed-size arrays. It seems very obvious to me, and so I'd expect someone to have thought of it and named it already. Does anyone know what this is called: Take a small fixed-size array. If the number of elements you want to put in your array is greater than the size of the array, add a new array and whatever pointers you like between the old and the new. Thus you have: Static array ————————————————————————— |1|2|3|4|5|6|7|8|9|a|b|c| ————————————————————————— Linked list ———— ———— ———— ———— ———— |1|*->|2|*->|3|*->|4|*->|5|*->NULL ———— ———— ———— ———— ———— My thing: ———————————— ———————————— |1|2|3|4|5|*->|6|7|8|9|a|*->NULL ———————————— ————————————

  • Some printers are merged into control panel on Windows 7

    - by Bertrand SCHITS
    I install the same printer several times to allow easy selection for users. They just choose the desired printer to have the corresponding functionnality (instead of going to printer properties and change them back and forth): one with double-sided printing, one for draft quality, one for upper tray, etc. On Windows 7, when I install a printer several times, the control panel's printers icons are merged. I then have only one icon for two or three identical printers. I can right-clic on the icon to display the usual menu, and some items of the menu have an arrow to access each printer. This is very missleading for users and admins. I have this behaviour on some computers, when others don't exhibit this. I didn't found what is the difference between computers with and without the problem. Anyone know how to prevent this ?

  • How to to dump JS array... (boommarklet?)

    - by Soulhuntre
    A page on a site I use is holding some of my data hostage. Once I have logged into the site and navigated to the right page, the data I need is in the array eeData[] - it is 720 elements long (once every 2 minutes of a given day). Rather than simulate the requests to the underlying stuff json supplier and since its only once a day, I am happy to simply develop a bookmarklet to grab the data - preferably as a XML or CSV file. Any pointers to sample code or hints would help. I found a bookmarklet here that is based on this script that does part of this - but I am not up to speed on any potential JS file IO to see if it is possible to induce a file "download" of the data, or pop it opn in a new window I can copy / paste.

  • Released object crashes app

    - by John Smith
    I am using objective-C++ (+Boost) for iPhone development. I am in a rather tight loop and need to allocate and release a certain object. The code is something like this. for (int i=0;i<100;i++) { opt = [[FObj alloc] init]; //do stuff with opt [opt release]; } The FObj object is something like @interface FObj MyCPPObj * cppobj; @end In the implementation of FObj there is a dealloc method: -(void) dealloc { delete cppobj; //previously allocated with 'new' [super dealloc]; } I am afraid that if i don't release then the 'MyCPPObj's will just pile up. But releasing makes the app crash after the first loop. What am I doing wrong? Or perhaps should I make cppobj and boost::shared_ptr? (do boost shared pointers automatically release their objects when an objective-C++ object is deleted?)

  • Looking for an array (vs linked list) hashtable implementation in C

    - by kingusiu
    hi, I'm looking for a hashtable implementation in C that stores its objects in (twodimensional) arrays rather than linked lists. i.e. if a collision happens, the object that is causing the collision will be stored in the next free row index rather than pushed to the head and first element of a linked list. plus, the objects themselves must be copied to the hashtable, rather than referenced by pointers. (the objects do not live for the whole lifetime of the program but the table does). I know that such an implementation might have serious efficiency drawbacks and is not the "standard way of hashing" but as I work on a very special system-architecture i need those characteristics. thanks

  • Styled Javascript Popup that Connects to Database

    - by user269799
    I want to create a javascript popup box that contains text fields. I want to be able to style this box - using CSS - and I want the textfield entries to be Inserted into a MySQL database. Is this possible? I would be familiar with doing this through web forms and server side scripting but I need it to be a bit more client side this time to make things seem a bit faster. I am thinking I may need to learn some AJAX but any pointers would be a help. GF

  • How to pass and set a CGFloat by reference?

    - by mystify
    I want to make an method which takes an CGFloat by reference. Could I do something like this? - (void)doStuff:(CGFloat*)floatPointer I guess this must look different than other object pointers which have two of those stars. Also I'm not sure if I must do something like: - (void)doStuff:(const CGFloat*)floatPointer And of course, no idea how to assign an CGFloat value to that floatPointer. Maybe &floatPointer = 5.0f; ? Could someone give some examples and explain these? Would be great!

  • How Do I Map a Drive Network Share Using the Linux Terminal?

    - by nicorellius
    Still getting used to Linux, and the GUI is great. I have Ubuntu 10 and I can go to Network and see the Windows network. Then double clicking this gets me to the drives that are shared. Then when I go back to the terminal and use: cd ~/.gvfs I can see the mapped drives. But it would be nice if I could this without all the mouse clicking. So how do I map network drives in the terminal, something akin to net use for Windows.

  • Multiple dropdowns, combination check and filter

    - by Tom
    Using Javascript / jQuery, I'm trying to build a "combination checker" that will take the values of three (but can be more) dropdown lists and filter the options based on a supplied list of allowed combinations. For example: DROPDOWNS Field 1: - value_1 - value_2 Field 2: - value_3 Field 3: - value_4 - value_5 COMBINATIONS - value_1, value_3, value_5 - value_1, value_3, value_4 - value_2, value_3, value_5 When a user selects Field 3 - value_4, the unavailable options will be disabled - ie, Field 1 - value_2 (there is no combination that allows value_2 and value_4 to be selected together). It would be really great if someone could provide some pointers on how this can be achieved or just provide a fresh perspective - I'm going round in circles on this one!

  • update portlet without refreshing portal page

    - by mike
    I'm trying to create a simple agena portlet. Now I've developed a basic one using spring-portlet-mvc, it allows you to navigate to the next and previous month with thusly named links that invoke a previousMonth or nextMonth function in my controller. Now the problem I'm having is that this navigation causes my whole page to refresh. Now I was wondering what the best way to fix this was. I've been looking around a bit and it looks like jquery/ajax will do the trick, but since I don't have any experience yet with that technology I was wondering if anyone had any pointers/better ideas to solve my problem.

  • any simple jquery <table> paginators

    - by Mike
    I'm looking for a jquery plugin so I can paginate my html tables (the content of which is generated by a jsp c:forEach). But so far I haven't found anything that worked. The plugin doesn't need to be fancy, in fact something like the first example on http://dl.dropbox.com/u/4151695/html/pajinate-0.2/examples/example1.html would do fine. I'm still very new to jquery so I don't have the knowledge yet to write one myself. So does anyone have any pointers where I could find one?

  • Class Members Over Exports

    - by VirusEcks
    When Using DLLs or Code-injecting to be Specific this is an example class only intended for explaining class test { int newint1; char newchararray[512]; void (*newfunction1)( int newarg1 ); int newfunction2( bool newarg1, char newarg2 ) { return newint1; } } mynewclass1; that covers most common elements that's included in classes now when exporting this function to another DLL or application and missed an element of those, either data member or function member, private or public what happens or changed their order ? and if each function is assigned it's value when Code-Injecting like mynewclass1.newfunction1 = (void *)(newexportedfunction); what's the happens in this case, if members of the class are pointers that are assigned after class construction and then missed one member or changed their order ?

  • What are the pros & cons of these MySQL engines for OLTP -- XtraDB, PBXT, or TokuDB?

    - by Continuation
    I'm working on a social website with an approximate read/write split of 90/10. Trying to decide on a MySQL engine. The ones I'm interested in are: XtraDB PBXT TokuDB What are the pros and cons of them for my use case? A few specific questions: PBXT uses log-based structure that avoids double-writes. It sounds very elegant, but the benchmark I've seen doesn't show any/much advantages over XtraDB. Do you have any experience with PBXT/XtraDB you can share? TokuDB sounds VERY interesting. But all the benchmarks I've seen are about single-threaded bulk inserts - inserting 100M rows for example. that's not very relevant for OLTP. What about its performance with large number of concurrent threads writing and reading at the same time? Anyone has tried that?

  • SQL Server column level security

    - by user46372
    I think I need some pointers on security in SQL Server. I'm trying to restrict some of our end users from getting access to certain columns (i.e. SSN) on a table. I thought I could just use column level security to restrict access to the columns. That successfully prevented users from accessing the table directly, but I was surprised that they could still get to those columns through a view that accessed that table. I followed the tips here: http://www.mssqltips.com/sqlservertip/2124/filtering-sql-server-columns-using-column-level-permissions/ Those were very helpful, but when I created a view at the end, the intern was able to access that column by default I've read that views are the best way to accomplish this, but I really don't want to go through and change all of the views and the legacy front-end application. I would rather just restrict it once on the table and if a view tries to access that column it would just fail. Is that possible or am I misunderstanding how security works in SQL Server?

  • C++ Vector at/[] operator speed

    - by sub
    In order to give functions the option to modify the vector I can't do curr = myvec.at( i ); doThis( curr ); doThat( curr ); doStuffWith( curr ); But I have to do: doThis( myvec.at( i ) ); doThat( myvec.at( i ) ); doStuffWith( myvec.at( i ) ); (as the answers of my other question pointed out) I'm going to make a hell lot of calls to myvec.at() then. How fast is it, compared to the first example using a variable to store the result? Is there a different option for me? Can I somehow use pointers? When it's getting serious there will be thousands of calls to myvec.at() per second. So every little performance-eater is important.

  • PING through batch file (looping problem)

    - by pradeetp
    I created a .BAT file in Windows 7 that has the following lines: PING XXX.XXX.XXX.XXX -t (XXX replaces the actual IP number). However, when I double click on this batch file, I can see the PING command repeatedly being executed in a loop. I even tried to rename the .BAT to .CMD but the result is the same. I want to avoid writing PING command through the Command Prompt, which is why I created the batch file. I don't know why the PING command is being continuously called when the same statement is put in a batch file.

  • iPhone app getting XML then refreshing it at intervals...

    - by user157733
    I have an app which gets some data from the web via an XML document. I have this working fine and have followed apples SeismicXML example (uses NSURLRequest etc). I am very new to this so I have to admit that I do not totally understand all the code that gets the XML - but it is working. My problem is that my app may be running for some time so I want to be able to refresh the XML every now and again and check to see if it is different. If it is different I need to update my contents. Basically this means my questions are.... Is there a standard way of doing this? I was thinking of creating a timer to call the function which parses the XML but I can't figure out which function to call. If anyone can give me any pointers or even better examples of this it would be fab. Thanks

  • How to maintain GridPane's fixed-size after adding elemnts dynamically

    - by Eviatar G.
    I need to create board game that can be dynamically change. Its size can be 5x5, 6x6, 7x7 or 8x8. I am jusing JavaFX with NetBeans and Scene builder for the GUI. When the user choose board size greater than 5x5 this is what happens: This is the template on the scene builder before adding cells dynamically: To every cell in the GridPane I am adding StackPane + label of the cell number: @FXML GridPane boardGame; public void CreateBoard() { int boardSize = m_Engine.GetBoard().GetBoardSize(); int num = boardSize * boardSize; int maxColumns = m_Engine.GetNumOfCols(); int maxRows = m_Engine.GetNumOfRows(); for(int row = 0; row < maxRows ; row++) { for(int col = maxColumns - 1; col >= 0 ; col--) { StackPane stackPane = new StackPane(); stackPane.setPrefSize(150.0, 200.0); stackPane.getChildren().add(new Label(String.valueOf(num))); boardGame.add(stackPane, col, row); num--; } } boardGame.setGridLinesVisible(true); boardGame.autosize(); } The problem is the stack panes's size on the GridPane are getting smaller. I tried to set them equal minimum and maximum size but it didn't help they are still getting smaller. I searched on the web but didn't realy find same problem as mine. The only similar problem to mine was found here: Dynamically add elements to a fixed-size GridPane in JavaFX But his suggestion is to use TilePane and I need to use GridPane because this is a board game and it more easier to use GridPane when I need to do tasks such as getting to cell on row = 1 and column = 2 for example. EDIT: I removed the GridPane from the FXML and created it manually on the Controller but now it print a blank board: @FXML GridPane boardGame; public void CreateBoard() { int boardSize = m_Engine.GetBoard().GetBoardSize(); int num = boardSize * boardSize; int maxColumns = m_Engine.GetNumOfCols(); int maxRows = m_Engine.GetNumOfRows(); boardGame = new GridPane(); boardGame.setAlignment(Pos.CENTER); Collection<StackPane> stackPanes = new ArrayList<StackPane>(); for(int row = 0; row < maxRows ; row++) { for(int col = maxColumns - 1; col >= 0 ; col--) { StackPane stackPane = new StackPane(); stackPane.setPrefSize(150.0, 200.0); stackPane.getChildren().add(new Label(String.valueOf(num))); boardGame.add(stackPane, col, row); stackPanes.add(stackPane); num--; } } this.buildGridPane(boardSize); boardGame.setGridLinesVisible(true); boardGame.autosize(); boardGamePane.getChildren().addAll(stackPanes); } public void buildGridPane(int i_NumOfRowsAndColumns) { RowConstraints rowConstraint; ColumnConstraints columnConstraint; for(int index = 0 ; index < i_NumOfRowsAndColumns; index++) { rowConstraint = new RowConstraints(3, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, VPos.CENTER, true); boardGame.getRowConstraints().add(rowConstraint); columnConstraint = new ColumnConstraints(3, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, HPos.CENTER, true); boardGame.getColumnConstraints().add(columnConstraint); } }

  • Fast comparison of char arrays?

    - by StackedCrooked
    I'm currently working in a codebase where IPv4 addresses are represented as pointers to u_int8. The equality operator is implemented like this: bool Ipv4Address::operator==(const u_int8 * inAddress) const { return (*(u_int32*) this->myBytes == *(u_int32*) inAddress); } This is probably the fasted solution, but it causes the GCC compiler warning: ipv4address.cpp:65: warning: dereferencing type-punned pointer will break strict-aliasing rules How can I rewrite the comparison correctly without breaking strict-aliasing rules and without losing performance points? I have considered using either memcmp or this macro: #define IS_EQUAL(a, b) \ (a[0] == b[0] && a[1] == b[1] && a[2] == b[2] && a[3] == b[3]) I'm thinking that the macro is the fastest solution. What do you recommend?

  • Guidelines for solution source code organisation(OO/DDD)

    - by fearofawhackplanet
    I'm starting on my first business project (.NET) and am trying to follow DDD principles. Are there any guidelines or common patterns for orgaining source code and namespaces? For example, do your domain objects go in a namespace MyProject.Domain or whatever? Would you separate the concrete implementations and the interfaces? In different namespaces? Different folders? Different solutions? I know a lot of this is subjective and dependent on project size, but a few pointers or suggestions to get started on a relatively small but extensible n-tier project would be useful.

  • StringListProperty limited to 500 char strings (Google App Engine / Python)

    - by MarcoB
    It seems that StringListProperty can only contain strings up to 500 chars each, just like StringProperty... Is there a way to store longer strings than that? I don't need them to be indexed or anything. What I would need would be something like a "TextListProperty", where each string in the list can be any length and not limited to 500 chars. Can I create a property like that? Or can you experts suggest a different approach? Perhaps I should use a plain list and pickle/unpickle it in a Blob field, or something like that? I'm a bit new to Python and GAE and I would greatly appreciate some pointers instead of spending days on trial and error...thanks!

  • Giving users a "reputation system" - Should I... ?

    - by RadiantHex
    Hi folks, I'm thinking of adding a reputation system to a web application, the site is already being used so I'm trying to be careful about my choices. I'm developing in Django/Python, thought this would be important. Reputation is generated in all actions that contribute to the site, similar to Stackoverflow's system. I know there are literally millions of ways of implementing this, and this is why I feel quite lost. Two alternatives I am not sure about are: Keep track of reasons why reputation was incremented Ignore reasons in order to reduce complexity of the site and overhead Would be happy with a few pointers, and directions. Would be very much appreciated!
