  • Can a CWinApp be placed in a DLL?

    - by jmucchiello
    I'm updating some legacy apps to Visual Studio 10 and am in linker hell. All of these DLLs derive classes from CWinApp and use AfxGetApp() to get access to the object. When I link the DLLs I get unresolved externals that look like global static objects that would get pulled in by a normal app's main(): Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass const CException::classCException" (?classCException@CException@@2UCRuntimeClass@@B) Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass const CFrameWnd::classCFrameWnd" (?classCFrameWnd@CFrameWnd@@2UCRuntimeClass@@B) Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static class CRect const CFrameWnd::rectDefault" (?rectDefault@CFrameWnd@@2VCRect@@B) My current combination of ignore default libraries and additional libraries (the method you can easily google to find the answer to linker hell) is: msvcprtd.lib,mfc100d.lib,mfcs100d.lib,libcmtd.lib When I add nafxcwd.lib (the mfc library), these three external symbols resolve but I end up with a bunch of other duplicate symbols (requiring the use of /FORCE:MULTIPLE) and in end __argc and __argv become unresolved. So the basic question is: Can you link a DLL containing a CWinApp in VS10? How do you setup the linker to do it?

  • Swapping an image during web development

    - by detly
    I'm trying to see what a certain webpage would look like if I replaced a certain image with another. Rather than upload the image, edit the site, etc, each time I tweak it, I'd like to know if there's a way to change the image in the page to my local version while viewing the remote page. I use Firebug for debugging web development usually, but I'm open to any other tool that might do this. (It is absolutely impossible to search for this and find anything but questions about dynamic image swapping on a deployed website, so sorry if this is a duplicate.)

  • Catching constraint violations in JPA 2.0.

    - by Dennetik
    Consider the following entity class, used with, for example, EclipseLink 2.0.2 - where the link attribute is not the primary key, but unique nontheless. @Entity public class Profile { @Id private Long id; @Column(unique = true) private String link; // Some more attributes and getter and setter methods } When I insert records with a duplicate value for the link attribute, EclipseLink does not throw a EntityExistsException, but throws a DatabaseException, with the message explaining that the unique constraint was violated. This doesn't seem very usefull, as there would not be a simple, database independent, way to catch this exception. What would be the advised way to deal with this? A few things that I have considered are: Checking the error code on the DatabaseException - I fear that this error code, though, is the native error code for the database; Checking the existence of a Profile with the specific value for link beforehand - this obviously would result in an enormous amount of superfluous queries.

  • Compiler/Linking Error: Freedup

    - by nym
    I've been trying to compile a program for hardlinking duplicate files called freedup. I did try to email the author/maintainer of the program, but it's been a long time and I haven't heard anything back from him. I'm trying to compile the program from a cygwin environment using the latest stable versions of gcc (3.4.4-999) and make (3.81-2). I've tried deleting all the object files and running make, but I always get the following error: freedup.o: In function 'main': /home/[user]/freedup-1.5/freedup.c:1791: undefined reference to '_hashed' collect2: ld returned 1 exit status make: * * * [freedup] Error 1 I did take a look at the source code and saw that the "hashed" function is an inline function (which I didn't think had to be declared outside of the source file... but that's just what I gathered from some preliminary googling). If anyone would be kind enough to try compiling this program in a windows environment and has any luck, I'd really appreciate it. Thanks The direct link for the source files is: http://freedup.org/freedup-1.5-3-src.tgz

  • PHP MySQL INSERT fails due to unique constraint

    - by sjw
    On insert I am catching the unique constraint mysql_errno() 1062. This works fine but I want to find the existing row to re-instate or modify it. Is there are method to obtain the row id on insert fail? I tried mysql_insert_id() but realised that would only return the row I'm inserting (or failed to insert) therefore, I get 0. Is there no option but to issue another mysql_query and simply perform a select on the duplicate value? I just want to make sure there is no better, quicker, more economical way to do this.

  • Separating null byte separated UNICODE C string.

    - by Ramblingwood
    First off, this is NOT a duplicate of: http://stackoverflow.com/questions/1911053/turn-a-c-string-with-null-bytes-into-a-char-array , because the given answer doesn't work when the char *'s are Unicode. I think the problem is that because I am trying to use Unicode and thus wchar_t instead of char, the length of each character is different and thus, this doesn't work (it does in non-unicode): char *Buffer; // your null-separated strings char *Current; // Pointer to the current string // [...] for (Current = Buffer; *Current; Current += strlen(Current) + 1) printf("GetOpenFileName returned: %s\n", Current); Does anyone have a similar solution that works on Unicode strings? I have been banging my head on the this for over 4 hours now. C doesn't agree with me.

  • Python command line UI

    - by hdx
    Hey guys/gals I'm writing a python script that fixes some duplicate issues on my database. I would like to display some progress status to the users, currently I just print it like this: print "Merged " + str(idx) + " out of " + str(totalCount); The problem is that it prints that in a new line for every record and that does not look so good :) I'd like to either always print the string above on the same line on the screen or use some smart widget that displays it in some sort of progress bar. I intent to run this on the command line, any suggestions will be much appreciated.

  • database vs flat file, which is a faster structure for regex matching with many simultaneous request

    - by Jamex
    Hi, which structure returns faster result and/or less taxing on the host server, flat file or database (mysql)? Assume many users (100 users) are simultaneously query the file/db. Searches involve pattern matching using regex against a static file/db. File has 50,000 unique lines (same data type). There could be many matches. There is no writing to the file/db, just read. Is it possible to have a duplicate the file/db and write a logic switch to use the backup file/db if the main file is in use? Which language is best for the type of structure? Perl for flat and PHP for db? TIA

  • Left with extra UITableViewCell after re-ordering

    - by Mark F
    After going into Edit mode, moving a cell, and leaving edit mode, i am left with one extra cell sitting on top of its duplicate cell while still in edit mode. The problem has to be somewhere in here: - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath { NSMutableArray *array = [[fetchedResultsController fetchedObjects] mutableCopy]; id objectToMove = [[array objectAtIndex:sourceIndexPath.row] retain]; [array removeObjectAtIndex:sourceIndexPath.row]; [array insertObject:objectToMove atIndex:destinationIndexPath.row]; [objectToMove release]; for (int i=0; i<[array count]; i++) { [(NSManagedObject *)[array objectAtIndex:i] setValue:[NSNumber numberWithInt:i] forKey:@"userOrder"]; } [array release]; } Any guidance greatly appreciated!

  • Problem with assigning elements of a class array to individual variables in MATLAB

    - by Marc
    This is a bit of a duplicate of this question, this question, and this question, however those solutions don't work, so I'm asking mine. I've got an array of locally defined classes and I'd like to assign it to multiple, individual variables. This pattern doesn't work: %a is 2x1 of MyClass temp = mat2cell(a); [x,y] = temp{:}; %throws: ??? Insufficient number of outputs from right hand side of equal sign to satisfy assignment. Because temp is a single cell, with my 2x1 array in one cell, rather than a 2x1 cell array with one element of each of my original array in one cell. Any ideas?

  • Using a Cross Thread Boolean to Abort Thread

    - by Jon
    Possible Duplicate: Can a C# thread really cache a value and ignore changes to that value on other threads? Lets say we have this code: bool KeepGoing = true; DataInThread = new Thread(new ThreadStart(DataInThreadMethod)); DataInThread.Start(); //bla bla time goes on KeepGoing = false; private void DataInThreadMethod() { while (KeepGoing) { //Do stuff } } } Now the idea is that using the boolean is a safe way to terminate the thread however because that boolean exists on the calling thread does that cause any issue? That boolean is only used on the calling thread to stop the thread so its not like its being used elsewhere

  • MySQL INSERT data does not get stored in proper db, only temporary?

    - by greye
    I'm having trouble with MySQL or Python and can't seem to isolate the problem. INSERTs only seem to last the run of the script and are not stored in the database. I have this script: import MySQLdb db = MySQLdb.connect(host="localhost", user="user", passwd="password", db="example") dbcursor = db.cursor() dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'before: '+str(temp) dbcursor.execute('INSERT INTO tablename (data1, data2, data3) VALUES ("1", "a", "b")') dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'after: '+str(temp) The first time I run it I get the expected output: >>> before: () after: ((1L, 'a', 'b'),) The problem is that if I run it again, the before comes out empty when it should already have the entry in it and the after doesn't break (data 1 is primary key). >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) If I try running the insert command twice in the same script it will break ("Duplicate entry for PRIMARY KEY") Any idea what might be happening here?

  • If you delete a DOM element, do any events that started with that element continue to bubble?

    - by Matt
    What behavior should I expect if I delete a DOM element that was used to start an event bubble, or whose child started the event bubble - will it continue to bubble if the element is removed? For example - lets say you have a table, and want to detect click events on the table cells. Another piece of JS has executed an AJAX request that will eventually replace the table, in full, once the request is complete. What happens if I click the table, and immediately after the table gets replaced by a successful completion of an AJAX request? I ask because I am seeing some behavior where the click events don't seem to be bubbling - but it is hard to duplicate. I am watching the event on a parent element of the table (instead of attaching the event to every TD), and it just doesn't seem to reach it sometimes.

  • Flex 3 / ColdFusion Session Issue?

    - by dcolumbus
    Alright so this is an odd one... I have an application built in ColdFusion with a lot of the interactivity done with Flex. When a user logs in, there are session variables, as well as the client session that is evoked. When you browse to any given Flex Application, the variables are read in a used accordingly... however, on Windows (it seems XP and maybe others) for some reason session information like USER are randomly undefined... Could this be an issue with the session timing out? Even if I force a logout and log back in, it doesn't really seem to fix the issue... mind you, I cannot duplicate the bug myself, but it constantly happens on PCs.

  • Jpa subclass mapping

    - by Roy Chan
    I am making a POS like system. I wonder how to map subclass using JPA (this is for my DAO). Product class has product details and OrderProduct class has information about the Product and details about the order. @Entity @Table(name="products") public class Product implements Serializable{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO public int getId(){ return id;} /** Other get/set methods */ } @Entity @Table(name="order_products") public class OrderProduct extends Product{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO) public int getId(){ return id;} /** Other get/set methods */ } I got complain about duplicate @Id. But OrderProduct class really need another id than the product one. How should I map this? DB is something like this Table products id int name varchar(32) Table order_product id int quantity int productid int fk referencing product table Would @IdClass or @AttributeOverride help?

  • problem with parsing string from excel file

    - by ohana
    hi, i have ruby code to parse data in excel file using Parseexcel gem. I need to save 2 columns in that file into a Hash, here is my code: worksheet.each { |row| if row != nil key = row.at(1).to_s.strip value = row.at(0).to_s.strip if !parts.has_key?(key) and key.length 0 parts[key] = value end end } however it still save duplicate keys into the hash: "020098-10". I checked the excel file at the specified row and found the difference are " 020098-10" and "020098-10". the first one has a leading space while the second doesn't. I dont' understand is it true that .strip function already remove all leading and trailing white space? also when i tried to print out key.length, it gave me these weird number: 020098-10 length 18 020098-10 length 17 which should be 9....

  • Why Is my UISlider Thumb Image Being Shown Multiple Times and Not Disappearing As They Should?

    - by Gorgando
    This slider is possessed: When I move the slider thumb left or right, it leaves the original image there (creating an extra image). This doesn't happen every time and the only consistency i've noticed is that it's inconsistent. When the table is in "Editing mode" it is more likely to create a duplicate thumb image, but it also does so in regular mode. This is the code that I use to create the slider: CGRect frame = CGRectMake(20, 42.0, 280.0, 22); self.slider = [[UISlider alloc] initWithFrame:frame]; [self.slider addTarget:self action:@selector(sliderAction:) forControlEvents:UIControlEventValueChanged]; self.slider.continuous = YES; self.slider.minimumValue = 0.0; self.slider.maximumValue = 5.0; self.slider.value = 0.0; [sliderCell addSubview:self.slider]; Appreciate any thoughts you might have!

  • Need an alternative to two left joins.

    - by Scarface
    Hey guys quick question, I always use left join, but when I left join twice I always get funny results, usually duplicates. I am currently working on a query that Left Joins twice to retrieve the necessary information needed but I was wondering if it were possible to build another select statement in so then I do not need two left joins or two queries or if there were a better way. For example, if I could select the topic.creator in table.topic first AS something, then I could select that variable in users and left join table.scrusersonline. Thanks in advance for any advice. SELECT * FROM scrusersonline LEFT JOIN users ON users.id = scrusersonline.id LEFT JOIN topic ON users.username = topic.creator WHERE scrusersonline.topic_id = '$topic_id' The whole point of this query is to check if the topic.creator is online by retrieving his name from table.topic and matching his id in table.users, then checking if he is in table.scrusersonline. It produces duplicate entries unfortunately and is thus inaccurate in my mind.

  • Best C++ Linux IDE [closed]

    - by Idan
    Possible Duplicate: Best unix/linux C++ debuger/IDE ? Hey, I've been searcing and reading about a good Linux C++ IDE, and couldn't set my mind on the right one. I've been using Eclipse with the C++ pluging , for C development, for the last couple months, but I found it not very useful, especially the debugging process that was quite annoying. I love Vistal Studio, so I'm looking for something really close to it. I need an IDE that will provide me, among other things: - rich debugging options - easy to use graphical designer - underscores error/warning (before I compile - like eclipse has) - Intellisense and more... Any suggestion? Maybe NetBeans?

  • Visual Studio: What approach do you use to 'template' plumbing for similiar projects?

    - by Sosh
    When building ASP.NET projects there is a certain amount of boilerplate, or plumbing that needs to be done, which is often identical across projects. This is especially the case with MVC and ALT.NET approaches. [I'm thinking of things such as: IoC, ORM, Solution structure (projects), Session Management, User Management, I18n etc.] I would like to know what approach you find best for 'reusing' this plumbing accross projects? Have a 'master solution' which you duplicate and rename somehow? (I'm using a this to a degree at the moment, but it's fairly messy. Would be interested how people do this 'better') Mainly rely on Shared Library projects? (I find this appropriate for some things, but too restrictive for things that have to be customised) Code generation tools, such as T4? (Similar to the approach used by SharpArchitecture - have not tried this myself) Something else? Thanks for sharing your experiences!

  • Django - Tips to avoid repeating code in views

    - by D Roddis
    I'm moving from a PHP background into Django development via python, mostly for the sake of tackling a MVC (or MVT) that I feel makes the most sense, although in this pattern I've started to notice a lot of repeated code in my views. For example, when logged in I have information regarding the user that I would like to appear on every page, although when using render_to_response and in every view this is required I have to grab the information and pass it to the render_to_response function. I'm wondering what would be the most efficient way to cut down on the duplicate code which would in essence be required in all views in a particular app. Thanks in advance.
