• How to float a <div> echoed in the footer over a <div> located elsewhere (PHP/jQuery/HTML/CSS)

  - by PlasmaFlux

  Hello All! I'm embarking on a major project, but am stuck on a tiny issue at the very start. I'll try to be as concise as possible. I have a PHP script that will be echoing into the footer of the page (the last stuff before a bunch of s containing visible buttons and s containing hidden dialog boxes. The plan is to have the buttons float in the upper-right corner of corresponding s in the main content area of the page. i.e. - button-1 echoed into the footer will float in the corner of content-box-1, and will be tied to the hidden 'dialog-1'. I'll be using jQuery and jQuery UI Dialog throughout the page(s). I'm not sure if that's particularly relevant to this question, but thought it worth mentioning just in case. So my question, put simply, is how do I echo a Button 1 into the footer with PHP, but have it float in the upper-right corner (with maybe 5px margin) of Content 1 is full of content? A picture says a thousand words: As shown above, I want the little blue gear button things in the corner of content pieces, locked and loaded with hidden s containing dialog boxes. Again, the catch is that all buttons and hidden divs will be the very last items echoed into the page footer. I've found plenty of info on how to float divs on top of divs, but all the examples I saw showed the s in close proximity to each other in the page source; not with a hundred lines of source code between the two s I'm not sure if the solution is pure CSS, pure jQuery/jQueryUI or a combination of the two. Any advice will be much appreciated. Thanks!

• Are there scenarios where the ViewModel needs to invoke methods on the View w.r.t. MVVM in WPF?

  - by Gishu

  As per the pattern, the ViewModel exposes Properties(with change notification) and Commands (to notify the VM of user actions) that the View binds to. The only communication that flows from the VM to the View is the property change notifications (so that the View can refresh itself with updated data). In MVP or PresentationModel form of the pattern (if I'm not mistaken), the View implements a plain vanilla interface (consisting of methods, properties and/or events). With MVVM, it feels methods on the IView have been outlawed (along with IView itself). One scenario I could think of was to set the focus to a certain control in the View. (When the user does ActionX, the focus should immediately be set to FieldY). In MVP, I'd write this as IView.ActivateField(NameConstant), which the presenter or PM would invoke. In MVVM, this seems to be a fringe case that needs a workaround / little bit of code-behind. The VM implements an ActiveField Property, which it sets to NameConstant. The view picks up the change notification event and in a code-behind event handler, activates the Name control. Is the above just an exception to the norm? Or are there other such scenarios, where the VM needs to invoke a method on the View ?

• PHP $_SERVER['HTTP_HOST'] vs. $_SERVER['SERVER_NAME'], am I understanding the man pages correctly?

  - by Jeff

  I did a lot of searching and also read the PHP $_SERVER man page. Do I have this right regarding which to use for my PHP scripts for simple link definitions used throughout my site? $_SERVER['SERVER_NAME'] is based on your web servers' config file (Apache2 in my case), and varies depending on a few directives: (1) VirtualHost, (2) ServerName, (3) UseCanonicalName, etc. $_SERVER['HTTP_HOST'] is based on the request from the client. Therefore, it would seem to me that the proper one to use in order to make my scripts as compatible as possible would be $_SERVER['HTTP_HOST']. Is this assumption correct? Followup comments: I guess I got a little paranoid after reading this article and noting that someone said "they wouldn't trust any of the $_SERVER vars": http://markjaquith.wordpress.com/2009/09/21/php-server-vars-not-safe-in-forms-or-links/ and also: http://www.php.net/manual/en/reserved.variables.server.php (comment: Vladimir Kornea 14-Mar-2009 01:06) Apparently the discussion is mainly about $_SERVER['PHP_SELF'] and why you shouldn't use it in the form action attribute without proper escaping to prevent XSS attacks. My conclusion about my original question above is that it is "safe" to use $_SERVER['HTTP_HOST'] for all links on a site without having to worry about XSS attacks, even when used in forms. Please correct me if I'm wrong.

• How to allow anonymous login in org.apache.ftpserver?

  - by ablmf

  I wrote a little code like this to start an ftp server embedded in my application. It's based on apache ftpserver I found that anonymous user could not login. Client keeps get 530. Do I have add a configure file for ftp? I can not find any API to create a User to add to UserManger. private void start_ftp() throws FtpException { FtpServerFactory serverFactory = new FtpServerFactory(); ListenerFactory factory = new ListenerFactory(); // set the port of the listener factory.setPort(DEF_FTP_PORT); // replace the default listener serverFactory.addListener("default", factory.createListener()); Ftplet fl = new MyFtplet(); Map<String, Ftplet> map_ftplest = new LinkedHashMap<String, Ftplet>(); map_ftplest.put("default", fl); serverFactory.setFtplets(map_ftplest); UserManagerFactory u_factory = new PropertiesUserManagerFactory(); UserManager u_manager = u_factory.createUserManager(); //u_manager.

• Is this an example of LINQ-to-SQL?

  - by Edward Tanguay

  I made a little WPF application with a SQL CE database. I built the following code with LINQ to get data out of the database, which was surprisingly easy. So I thought "this must be LINQ-to-SQL". Then I did "add item" and added a "LINQ-to-SQL classes" .dbml file, dragged my table onto the Object Relational Designer but it said, "The selected object uses an unsupported data provider." So then I questioned whether or not the following code actually is LINQ-to-SQL, since it indeed allows me to access data from my SQL CE database file, yet officially "LINQ-to-SQL" seems to be unsupported for SQL CE. So is the following "LINQ-to-SQL" or not? using System.Linq; using System.Data.Linq; using System.Data.Linq.Mapping; using System.Windows; namespace TestLinq22 { public partial class Window1 : Window { public Window1() { InitializeComponent(); MainDB db = new MainDB(@"Data Source=App_Data\Main.sdf"); var customers = from c in db.Customers select new {c.FirstName, c.LastName}; TheListBox.ItemsSource = customers; } } [Database(Name = "MainDB")] public class MainDB : DataContext { public MainDB(string connection) : base(connection) { } public Table<Customers> Customers; } [Table(Name = "Customers")] public class Customers { [Column(DbType = "varchar(100)")] public string FirstName; [Column(DbType = "varchar(100)")] public string LastName; } }

• nhibernate - mapping with contraints

  - by Tobias Müller

  Hello everybody, I am having a Problem with my nhibernate-mapping and I can't find a solution by searching on stackoverflow/google/documentation. The database I am using has (amongst others) two tables. One is unit with the following fields: id enduring_id starts ends damage_enduring_id [...] The other one is damage, which has the following fields: id enduring_id starts ends [...] The units are assigned to a damage and one damage can have zero, one or more units working on it. Every time a unit moves to annother damage, the dataset is copied. The field "ends" of the old record and "starts" of the new record are set to the current time stamp, enduring_id stays the same. So if I want to know which units were working on a damage at a certain time, I do the following select: select * from unit join damage on damage.enduring_id = unit.damage_enduring_id where unit.starts <= 'time' and unit.ends = 'time' (This is not an actualy query from the database, I made it up to make clear what I mean. The the real database is a little more complex) Now I want to map it that way, so I can load all the damages which are valid at one time (starts <= wanted time <= ends) and that each of them has a Bag with all the attached units at that time (again starts <= wanted time <= ends). Is this possible within the mapping? Sorry if this is a stupid question, but I am pretty new to nhibernate and I have no clue how to do it. Thanks a lot for reading my post! Bye, Tobias

• JSF/Seam - new component instance on submit?

  - by purecharger

  And my confusion with JSF continues. This is a continuation of a question asked yesterday, but I feel it warrants a new question. I have a single seam component that expects a URL parameter to be injected for retrieving a List<String> from a method. This works perfectly on the first navigation to the page. The List is used to display many different selectOneRadio groups that populate a <h:form/>. Now on the submit, I cannot get the URL parameter to be injected or otherwise set on the component! Adding <h:inputHidden/> causes FacesExceptions to be thrown. Then I tried setting the List as an instance variable on the object, and when the subsequent call is made on the submit (which I also do not understand why that is done) I check to see if the variable is non-null: if it isn't, return it. Now I found that a new instance of the component is created on submit!!! getList() called this.toString(): .BeanAction@5fd98420 #### This is when submit is clicked getList() called this.toString(): .BeanAction@22aacbce The component has the following annotations: Stateful @Scope(ScopeType.CONVERSATION) @Name("bean") @Restrict("#{identity.loggedIn}") Can someone explain why there is a new instance of the component created? I'm really not quite sure how to go about handling this. I thought the hidden parameter would work, because that is how I would do it with straight HTML, and I'm a little surprised that its not working for JSF/Seam.

• How can I add a "Loading...Please wait..." feature?

  - by Rob

  I have a very simple table on my website, that displays different URL's. I have an input field where I can type in a URL and click 'Submit' to add additional URL's. However, I want to add an MD5 grabbing feature to this, using @md5_file(); to grab the MD5 of the URL and check to make sure it's the MD5 it should be, before adding it to the database. However it may take a few seconds for it to grab the MD5 and compare it, so I would like to add a little bit of text, like "Processing...Please wait..." while it does the comparing, and then once it's compared I want that text to go away. I've never done this before, or even though about doing it so I have no idea where to start. I'll go ahead and put javascript as a tag for this, since I'm guessing it would be done with javascript, but I really have no idea. I don't think it's possible with PHP, but again, I have no idea. Any suggestions?

• How to access device settings on a Sony Ericsson mobile phone?

  - by TheRHCP

  Edited on April 29th Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks. EDIT: It seems that I was totally wrong concerning my phone. This not based on any Symbian OS at all. This is pure Sony Ericsson so the only solution would be to look if Sony Ericsson extended J2ME functionality in their own JVM. I am gonna investigate on this.

• Converting FoxPro Date type to SQL Server 2005 DateTime using SSIS

  - by Avrom

  Hi, When using SSIS in SQL Server 2005 to convert a FoxPro database to a SQL Server database, if the given FoxPro database has a date type, SSIS assumes it is an integer type. The only way to convert it to a dateTime type is to manually select this type. However, that is not practical to do for over 100 tables. Thus, I have been using a workaround in which I use DTS on SQL Server 2000 which converts it to a smallDateTime, then make a backup, then a restore into SQL Server 2005. This workaround is starting to be a little annoying. So, my question is: Is there anyway to setup SSIS so that whenever it encounters a date type to automatically assume it should be converted to a dateTime in SQL Server and apply that rule across the board? Update To be specific, if I use the import/export wizard in SSIS, I get the following error: Column information for the source and the destination data could not be retrieved, or the data types of source columns were not mapped correctly to those available on the destination provider. Followed by a list of a given table's date columns. If I manually set each one to a dateTime, it imports fine. But I do not wish to do this for a hundred tables.

• Entity Framework 4 / POCO - Where to start?

  - by Basiclife

  Hi, I've been programming for a while and have used LINQ-To-SQL and LINQ-To-Entities before (although when using entities it has been on a Entity/Table 1-1 relationship - ie not much different than L2SQL) I've been doing a lot of reading about Inversion of Control, Unit of Work, POCO and repository patterns and would like to use this methodology in my new applications. Where I'm struggling is finding a clear, concise beginners guide for EF4 which doesn't assume knowledge of EF1. The specific questions I need answered are: Code first / model first? Pros/cons in regards to EF4 (ie what happens if I do code first, change the code at a later date and need to regenerate my DB model - Does the data get preserved and transformed or dropped?) Assuming I'm going code-first (I'd like to see how EF4 converts that to a DB schema) how do I actually get started? Quite often I've seen articles with entity diagrams stating "So this is my entity model, now I'm going to ..." - Unfortunately, I'm unclear if they're created the model in the designer, saved it to generate code then stopped any further auto-code generation -or- They've coded (POCO)? classes and the somehow imported them into the deisgner view? I suppose what I really need is an understanding of where the "magic" comes from and how to add it myself if I'm not just generating an EF model directly from a DB. I'm aware the question is a little vague but I don't know what I don't know - So any input / correction / clarification appreciated. Needless to say, I don't expect anyone to sit here and teach me EF - I'd just like some good tutorials/forums/blogs/etc. for complete entity newbies Many thanks in advance

• How to detect when video is buffering?

  - by Leon

  Hi guys, my question today deals with Flash AS3 video buffering. (Streaming or Progressive) I want to be able to detect when the video is being buffered, so I can display some sort of animation letting the user know to wait just a little longer. Currently my video will start up, hold on frame 1 for 3-4 secs then play. Kinda giving the impression that the video is paused or broken :( Update Thanks to iandisme I believe I'm faced in the right direction now. NetStatusEvent from livedocs. It seems to me that the key status to be working in is "NetStream.Buffer.Empty" so I added some code in there to see if this would trigger my animation or a trace statement. No luck yet, however when the Buffer is full it will trigger my code :/ Maybe my video is always somewhere between Buffer.Empty and Buffer.Full that's why it won't trigger any code when I test case for Buffer.Empty? Current Code public function netStatusHandler(event:NetStatusEvent):void { // handles net status events switch (event.info.code) { case "NetStream.Buffer.Empty": trace("¤¤¤ Buffering!"); //<- never traces addChild(bufferLoop); //<- doesn't execute break; case "NetStream.Buffer.Full": trace("¤¤¤ FULL!"); //<- trace works here removeChild(bufferLoop); //<- so does any other code break; case "NetStream.Buffer.Flush": trace("¤¤¤ FLUSH!"); //Not sure if this is important break } }

• Python template engine

  - by jturo

  Hello there, Could it be possible if somebody could help me get started in writing a python template engine? I'm new to python and as I learn the language I've managed to write a little MVC framework running in its own light-weight-WSGI-like server. I've managed to write a script that finds and replaces keys for values: (Obviously this is not how my script is structured or implemented. this is just an example) from string import Template html = '<html>\n' html += ' <head>\n' html += ' <title>This is so Cool : In Controller HTML</title>\n' html += ' </head>\n' html += ' <body>\n' html += ' Home | <a href="/hi">Hi ${name}</a>\n' html += ' </body>\n' html += '<html>' Template(html).safe_substitute(dict(name = 'Arturo')) My next goal is to implement custom statements, modifiers, functions, etc (like 'for' loop) but i don't really know if i should use another module that i don't know about. I thought of regular expressions but i kind feel like that wouldn't be an efficient way of doing it Any help is appreciated, and i'm sure this will be of use to other people too. Thank you

• how do I paste text to a line by line text filter like awk, without having stdin echo to the screen?

  - by Barton Chittenden

  I have a text in an email on a windows box that looks something like this: 100 some random text 101 some more random text 102 lots of random text, all different 103 lots of random text, all the same I want to extract the numbers, i.e. the first word on each line. I've got a terminal running bash open on my Linux box... If these were in a text file, I would do this: awk '{print $1}' mytextfile.txt I would like to paste these in, and get my numbers out, without creating a temp file. my naive first attempt looked like this: $ awk '{print $1}' 100 some random text 100 101 some more random text 101 102 lots of random text, all different 103 lots of random text, all the same 102 103 The buffering of stdin and stdout make a hash of this. I wouldn't mind if stdin all printed first, followed by all of stdout; this is what would happen if I were to paste into 'sort' for example, but awk and sed are a different story. a little more thought gave me this: open two terminals. Create a fifo file. Read from the fifo on one terminal, write to it on another. This does in fact work, but I'm lazy. I don't want to open a second terminal. Is there a way in the shell that I can hide the text echoed to the screen when I'm passing it in to a pipe, so that I paste this: 100 some random text 101 some more random text 102 lots of random text, all different 103 lots of random text, all the same but see this? $ awk '{print $1}' 100 101 102 103

• jQuery .attr() crashing Internet Explorer

  - by Sunyatasattva

  Hello everyone, This is my first time posting a question here, as I usually try to find solutions myself. This one, though, being an IE issue, just drives me crazy. I use jQuery cycle plug-in on a website I made and, to populate a caption div, I use a little function that is called after the image is loaded, which uses the "alt" attribute of the image. This seems to exasperate Internet Explorer, which, doesn't have the time to fulfill this apparently so-complicated task, and, as the slideshow cycles, it enters in an infinite loop and eventually crashes – the newer the version, the worse the crash: the older IEs just display an error message saying “The webpage cannot be displayed”, while the newer (7 and 8) completely crash the system. I have no idea on how to solve or work around this. Here is the problematic code. function changeCaption() { var caption = $("img", this).attr("alt"); $('#caption').fadeIn("slow").html(caption); } Thanks in advance for any pointer: I am amazed as how something so simple and globally recognized (didn't encounter any other browser who had problem with this), can cause a problem so big. I also read somewhere that being able to crash a browser remotely is a serious issue :) Lucio

• Using WCF to expose underlying process

  - by Steven

  I think I must be a little dull because I'm having so much difficulty with this. I use WCF for pretty much everything in-house, it's the most appropriate technology. I have a new Silverlight 3 app that is connecting to the WCF service and that's working fine. Where the problem begins is: Because of the expense in creating the objects within this service and the high correlation of individual objects being shared between clients I want to have a console application that basically gathers/calculates/caches all the data for the service 24/7 and the service basically connects to the console app (or whatever it is) and gets the pre-processed data. eg, think of it in terms of a stock reporting app (which it is). Person A has a portfolio of x, y z Person B has a portfolio of x, q, z, r The service needs to provide updated metrics on how their portfolio is performing. So instead of every 1 second processing person A, then person B, the app independently gathers the stock price and persons position information into memory and the service just queries the in memory result. Thanks for your help, I really am feeling dumb right now.

• Office 2003 interop problems, interface, method not found.

  - by Snake

  This problem is making me crazy. Actually I have multiple problems. First one: Why on earth are is there a _Worksheet and a Worksheetinterface in the Excel interop. They both look the same, except for some attributes on the methods. It's confusing! Second of all: my job today is making a VB.NET file more strict, by settings Option Strict On and Option Explicit On While it works for most files, I'm bumping into a problem. Here's a little code piece: Private _pivotTable As Excel.PivotTable With _pivotTable pvf = .AddDataField(pvc) End With PivotTable.AddDataField is defined on the MSDN page: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.pivottable.adddatafield(office.11).aspx When I check my local Interop dll w/ Reflector that method is NOT there. When I run the application, and step through it, the method just works. When I try to step INTO the method, I get an LateBound Exception. WTF? So the question is: why are the interfaces defined more than once (twice sometimes?). 2nd question. AddDataField trouble

• What's your most controversial programming opinion?

  - by Jon Skeet

  This is definitely subjective, but I'd like to try to avoid it becoming argumentative. I think it could be an interesting question if people treat it appropriately. The idea for this question came from the comment thread from my answer to the "What are five things you hate about your favorite language?" question. I contended that classes in C# should be sealed by default - I won't put my reasoning in the question, but I might write a fuller explanation as an answer to this question. I was surprised at the heat of the discussion in the comments (25 comments currently). So, what contentious opinions do you hold? I'd rather avoid the kind of thing which ends up being pretty religious with relatively little basis (e.g. brace placing) but examples might include things like "unit testing isn't actually terribly helpful" or "public fields are okay really". The important thing (to me, anyway) is that you've got reasons behind your opinions. Please present your opinion and reasoning - I would encourage people to vote for opinions which are well-argued and interesting, whether or not you happen to agree with them.

• Images in database vs file system

  - by Jesse

  We have a project coming up where we will be building a whole backend CMS system that will power our entire extranet and intranet with one package. The question I have been trying to find an answer to is which is better: storing images in the database (SQL Server 2005) so we may have integrity, single replication plan, etc OR storing on the file system? One issue we have is that we have multiple servers load balanced that require to have the same data at all times. As of now we have SQL replication taking care of that but file replication seems to be a little tougher. Another concern we have is that we would like to have multiple resolutions of the same image, we are not sure if creating and storing each version on the file system would be best or maybe dynamically pulling and creating the resolution image we would like upon request. Our concerns are the with the following: Data integrity Data replication Multiple resolutions Speed of database vs file system Overhead load of database vs file system Data management and backup Does anyone have a similar situation or have any input on what would be recommended? Thanks in advance for the help!

• Usability for content editors: Drupal or PHP framework?

  - by Jim

  Greetings: I am going to develop a basic Web site that supports some custom content types, is multilingual, and has content moderation workflow for a restricted group of content editors. This seems like an obvious choice for Drupal, except... the content editors will have little computer experience. In my opinion, that is a show-stopper for Drupal. For example, placing arbitrary inline images in content is a task that WordPress does well. I find Drupal's alternatives (IMCE, img_assist, etc.) clunky and not well integrated, and that will be a problem for this group of content editors. Also, none of the Drupal content workflow modules I tried seemed well-integrated; they all had a "tacked on" feel to them. As an admin I can understand why an "Accessible content" menu item (via Module Grants module) is necessary to view draft content (fixed in D7 but I can't wait for all the modules to be ported), but I'm pretty sure it'll confuse the content editors. An alternative is to use a PHP framework. I've read a few threads suggesting that it will take roughly the same amount of time using a good framework as it will to bend Drupal to my willing... maybe wishful thinking? I'm looking at Symfony, which gives me a basic auto-generated back-end, but which I believe I can customize to my heart's content. How do you make Drupal accessible to non-savvy content editors? If you recommend a PHP framework, which one? TIA!

• How to gray out HTML form inputs?

  - by typoknig

  What is the best way to gray out text inputs on an HTML form? I need the inputs to be grayed out when a user checks a check box. Do I have to use JavaScript for this (not very familiar with JScript) or can I use PHP (which I am more familiar with)? EDIT: After some reading I have got a little bit of code, but it is giving me problems. For some reason I cannot get my script to work based on the state of the form input (enabled or disabled) or the state of my checkbox (checked or unchecked), but my script works fine when I base it on the values of the form inputs. I have written my code exactly like several examples online (mainly this one) but to no avail. None of the stuff that is commented out will work. What am I doing wrong here? <label>Mailing address same as residental address</label> <input name="checkbox" onclick="disable_enable() "type="checkbox" style="width:15px"/><br/><br/> <script type="text/javascript"> function disable_enable(){ if (document.form.mail_street_address.value==1) document.form.mail_street_address.value=0; //document.form.mail_street_address.disabled=true; //document.form.mail_city.disabled=true; //document.form.mail_state.disabled=true; //document.form.mail_zip.disabled=true; else document.form.mail_street_address.value=1; //document.form.mail_street.disabled=false; //document.form.mail_city.disabled=false; //document.form.mail_state.disabled=false; //document.form.mail_zip.disabled=false; } </script>

• NSMenu doesn't start tracking

  - by Measunny

  Hey, I have a little cocoa app which usually operates in the background (as agent). Sometimes I'd like to be able to popup a contextmenu (no window or s.th. visible at this time). As I'm only targetting Snow Leopard I tried this: if (windows) { NSMenu *theMenu = [[[NSMenu alloc] initWithTitle:@"test"] autorelease]; [theMenu setShowsStateColumn:NO]; [theMenu setAutoenablesItems:NO]; for (id item in windows) { NSString *labelText = @"some text"; NSMenuItem *theMenuItem = [[[NSMenuItem alloc] initWithTitle:labelText action:@selector(menuItemSelected:) keyEquivalent:@""] autorelease]; [theMenuItem setTarget:self]; [theMenuItem setRepresentedObject:item]; [theMenuItem setEnabled:YES]; [theMenuItem setImage:icon]; [theMenu addItem:theMenuItem]; } [theMenu popUpMenuPositioningItem:nil atLocation:[NSEvent mouseLocation] inView:nil]; } The menu popsup perfectly but if I hover the items with the mouse cursor they don't highlight and I can't click them. The menuItemSelected: method looks just like this: -(IBAction)menuItemSelected:(id)sender { } Any idea what I'm doing wrong?

• C# DllImport with c++ const char* not working correctly

  - by Shammah

  I have the following function in a C++ DLL extern "C" __declspec(dllexport) bool Exist(const char* name) { //if (g_Queues.find(name) != g_Queues.end()) // return true; //else // return false; return false; } Inside my C# class I have the following: [DllImport("Whisper.dll", EntryPoint="Exist", CallingConvention=CallingConvention.Cdecl)] public static extern bool Exist(string name); Yet, whenever I call my function it ALWAYS returns true, even when I commented out my little function and made it return false. I have the feeling there is something wrong with my calling convention or any other issue with P/Invoking my DLL, probably corresponding with the string and const char*, but for now I am completely clueless. What am I doing wrong? Why does it return true instead of false? EDIT: I have figured out this has nothing to do with the const char* or string, because the problem persists with an empty function. I've tried changing the calling convention between Cdecl and StdCall and neither work correctly. I've also managed to debug my DLL and it's being called correctly and does indeed return false, but once back into C# it somehow is true. Changing the CharSet also had no effect. I've made sure I've supplied my C# program with the latest and correct version of my DLL each time, so that shouldn't be an issue aswell. Again, I am completely clueless on why the result is true when I'm in fact returning false. EDIT2: SOReader provided me with a suggestion which fixes another important issue, see my comment. Sadly, it does not fix the return issue.
