  • .Net Designer assemblies, C++\C# error

    - by greggorob64
    I'm working on an designer-heavy application (using Visual C++ 2.0, but a C# solution should still be relevant). My setup is this: I have a UserControl named "Host" I'm attempting a UserControl named "Child" Child contains a property to a class whose type is defined in a different dll entirely, named "mytools.dll" Child works just fine in the designer. However, when I go to drag "child" onto "host" from the designer, I get the following error: Failed to create component 'Child'. The error message follows: 'System.io.filenotfoundexception: could not load file or assembly MyTools, Version XXXXXX, Culture=neutral ..... {unhelpful callstack} If I comment out the property in "child" that points to the class in mytools.dll, everything designs just peachy. I have the property marked with "Browsable(false), and DesignerSerializable(hidden), and it does not help. Is there a way for me to explicitly say "Don't load this dll, you won't need it in design time", or some way for me to force a dll to load from the designer programmatically? Thanks!

  • Help with an SQL query on a single (comments) table (screenshot included)

    - by citrus
    Please see screenshot Goal: id like to have comments nested 1 level deep The comments would be arranged so that rating of the parent is in descending order the rating of the children comments is irrelevant The left hand side of the screenshot shows the output that Id like. The RHS shows the table data. All of the comments are held in 1 table. Im a beginner with SQL queries, the best I can do is: SELECT * FROM [Comments] WHERE ([ArticleId] = @ArticleId) ORDER BY [ThreadId] DESC, [DateMade] This somewhat does the job, but it obviously neglects the rating. So the above statement would show output where Bobs Comment and all of the children comments are before Amy's and her childrens comments. How can I run this query correctly?

  • Doxygen comments on declarations or on definitions?

    - by Arkaitz Jimenez
    Just started using Doxygen for documenting my code here and can't decide where to put them. At first look it seems better to put them in the declaration files as it is there where you actually declare what you receive, what you are going to return and stuff like that, apart from that things like data members that are only in the declaration files can obviously only documented there. But often I find handier to comment methods in the implementation files as they are more accessible to me and the declaration file doesn't get cluttered with dozens of lines of comments making it harder to find what you look for when developing. What is your experience with that?

  • How can CSS stop Google Maps loading?

    - by AP257
    I have a page with a Google Maps div: <div id="map_canvas" style="width: 100%; height: 332px;" ></div> If I comment out my CSS, the map loads fine: if I include the CSS, the map controls load, but the map tiles don't load: there's just a grey background. This is the case even if I put the map div just after the <body> tag, not within any styled element at all. No CSS, it loads fine. With CSS, no map. Does anyone know what could be causing this? I don't quite understand what the problem can be if no CSS styles are being applied to any element that contains the map. If more diagnostics are needed, please let me know, and I'll deploy the broken map onto a staging site, so people can look at the source.

  • How do I delete all tables in a database using SqlCommand?

    - by mafutrct
    Unlike the other posts about the task "delete all tables", this question is specifically about using SqlCommand to access the database. A coworker is facing the problem that no matter how it attempts it, he can't delete all tables from a database via SqlCommand. He states that he can't perform such action as long as there is an active connection - the connection by the SqlCommand itself. I believe this should be possible and easy, but I don't have much of a clue about databases so I came here to ask. It would be awesome if you could provide a short code example in C# (or any .NET language, for that matter). If you require additional information, just leave a comment.

  • Build Google App Engine Java source from Eclipse

    - by Robottinosino
    I would like to try to build Google App Engine for Java from source. I have tried this: I don't know how to solve the javac Ant task. I am on Mac OS X 10.6.8. The reason why I am trying to to create a Java Project from the source is that when I try to debug/step-into the sources downloaded from SVN, something is wrong in Eclipse and it does not track execution at the right code line. It seems to be executing "comment lines"? So I don't get an accurate tracking of the code path. I think what I would ideally need is: 1) svn checkout command with matching REV number of latest SDK 2) wget command downloading matching jar

  • session_start() Hangs The Server

    - by Narcissus
    Totally confused by this one... We have a WAMPServer installation set up, running a number of virtual hosts from various document roots. Just recently, one particular domain has started hanging the server. We traced it down to session_start(). If we comment it out, there are no problems (except, of course, for the fact that we can't do anything with the session). With it uncommented, it will hang the page load and, with enough reloads, will hang the entire server. All of the other sites still work perfectly with their sessions. As far as I know, there is nothing different with the way sessions are being worked with. I am looking further into it (in case someone changed something) but right now I'm hoping for some direction :) So, any thoughts?

  • Choosing the right and learning assembler for compiler-writing

    - by X A
    I'm writing a compiler and I have gone through all the steps (tokenizing, parsing, syntax tree structures, etc.) that they show you in all the compiler books. (Please don't comment with the link to the "Resources for writing a compiler" question!). I have chosen to use NASM together with alink as my backend. Now my problem is: I just can't find any good resources for learning NASM and assembly in general. The wikibook (german) on x86 assembly is horrible. They don't even explain the code they write there, I currently can't even get simple things like adding 1 to 2 and outputting the result working. Where can I learn NASM x86 assembly?

  • How to set specific column settings in JTable?

    - by HansDampf
    How can I make my JTable show specific stuff for each column? Can I use an Object for more than one column? I want to have a column showing the date (dd.mm.yyyy) and another to show the time (hh:mm) but as I have it now it only shows the String representation of the Date object as a whole. public class AppointmentTableModel extends AbstractTableModel { ... @Override public Object getValueAt(int rowIndex, int columnIndex) { return appointments.get(rowIndex).getByColumn(columnIndex); } } public class Appointment { ... public Object getByColumn(int columnIndex) { switch (columnIndex) { case 0: return date; case 1: return date; case 2: return sample; case 3: return sample; case 4: return history; case 5: return comment; } return null; } }

  • Why Doesn't This Java Code Skip Lines with #?

    - by Nathan
    I'm trying to allow an external .txt file that is read by a Java script be able to have some comments in the beginning of the file so others can easily edit it and add more to it. But if the file contains # (the sign designated for a line that is a comment) it just returns the error that there is a "Format Error in file" (the IOException - so it is getting past that first "IF"...) Can someone help? Here's the portion of the code that deals with commenting lines out of the .txt file being called earlier in the script: while ((line = br.readLine()) != null) { line = line.trim(); if (line.length() < 1 || line.charAt(0) == '#') { // ignore comments continue; } final String[] parts = line.split("="); if (parts.length != 2) { throw new IOException("Format error in file " + JLanguageTool.getDataBroker().getFromRulesDirAsUrl(getFileName()) + ", line: " + line); }

  • rails contoller defaults to respond with application/xml in production

    - by Dave Paroulek
    I have a standard contacts_controller.rb with index action that responds as follows: respond_to do |format| format.html format.xml { render :xml => @contacts } end In development, it works as intended: when I browse to http://localhost:3000/contacts, I get an html response. But, when I start the app using capistrano on a remote ubuntu server and browse to the same url, I get a xml response? If I go to http://remote_host:8000/contacts.html, then I see the html response. If I comment out the format.xml { render :xml => @contacts }, then I see the desired html response. Pretty sure I'm missing something subtle about difference between rails development and production modes? Any ideas about what I'm overlooking? Thanks, - Dave

  • Can any Texter users answer this question?

    - by Jared
    I have recently started using the excellent Texter. I wanted to set up a shortcut for creating html comments. However that it seems that the exclamation character (!) has special significance in the program, and so does not come out in script mode. This character is of course required for...<!-- html comment here --> Here is the code I tried to create the shortcut... {HOME}<!-- {END}{BS} --> Just wondering if there is a way of getting around this problem??

  • [PHP] md5(uniqid) makes sense for random unique tokens?

    - by Exception e
    I want to create a token generator that generates tokens that cannot be guessed by the user and that are still unique (to be used for password resets and confirmation codes). I often see this code; does it make sense? md5(uniqid(rand(), true)); According to a comment uniqid($prefix, $moreEntopy = true) yields first 8 hex chars = Unixtime, last 5 hex chars = microseconds. I don't know how the $prefix-parameter is handled.. So if you don't set the $moreEntopy flag to true, it gives a predictable outcome. QUESTION: But if we use uniqid with $moreEntopy, what does hashing it with md5 buy us? Is it better than: md5(mt_rand())

  • How to create a 'Hot or Not' website

    - by Casper
    Hi guys, I'd like to create a website with similar concept as 'Hot or Not' where users need to sign up to the website and then upload photos. Each photo can be given a description and some additional fields. Other users may comment and rate the photo entries. On top of that, users may favourite/bookmark (and remove) any photo entries and they're accessible via their profile page That's generally how the website will be. Can't decide on a CMS to use Somehow I'm at a crossroad here. I've done some research and found that Joomla has an extension that is able to pull this website off but the thing is I'm not that comfortable with using Joomla. I work with WordPress most of the time, but I can't seem to figure out how would I build this website with WordPress. Would using BuddyPress make it work? Would hiring a plugin developer to customize some plugins work? What do you guys think?

  • Does this popup view violate HIGS?

    - by brettr
    Will using a popup view to present a comment submission form violate the HIGS? I may have one popup with selections that goes to the final popup. Two popups back to back. This is more similar to a modal type of view than an alert or action sheet as described by the HIGS: http://developer.apple.com/iphone/library/documentation/UserExperience/Conceptual/MobileHIG/ModalViews/ModalViews.html#//apple_ref/doc/uid/TP40006556-CH11-SW1 under the section 'Using Modal Views'. Basically the type of view I'm shooting for is a combination of an alert with a custom view. It's sort of a mini view since it will be centered in the middle of the screen but not take up all of the viewing area. I'm fairly sure that is a violation however, but I'm looking for a few opinions on it. I believe what needs to happen is use a modal view, which will cover the entire view.

  • Android -- How to post app rating/comments to Market from within app?

    - by borg17of20
    Hello all, This is a simple question. Is there a way to allow users to enter in a comment and or rating for my app from directly within my app and have that data posted back to the Android Market? If so, what would the code for that look like if I used an EditText view to allow user input? If not, then is my only other option directly linking to my app in the Market (i.e. the user clicks the link in my app, or a button, and the Market app launches with my app page displayed)? For example: view.setOnClickListener( new OnClickListener(){ public void onClick(View v) { startActivity( new Intent( Intent.ACTION_VIEW, Uri.parse("market://details?id=packagename") ) ); } } *where "packagename" is replaced by my app's package name from the manifest. Thanks.

  • Stagger increments in C# NumericUpDown control

    - by mihe
    Hi cloud of wisdom :-) I am facing some trouble trying to configure a particular configuration for a NumericUpDown control in c#. Basically, I have seen that I can set the Increment interval, but I would like to manage the Increment interval depending on which arrow is clicked (up or down). I have checked the events of the control, but I do not find an event for each arrow. Basically, I want to achieve a control where, at different values, the increment is different. from 0.00 to 5.00 increments of 0.01, from 5.00 to 20.00 increments of 0.04, and so on Is this possible ? Note: It would be useful also an historic value in the control for the last value when the valuechanged event is trigger. Does this exist? Thanks in advance for any comment or suggestion!!!

  • what is the best and valid way for cross browser min-height?

    - by metal-gear-solid
    for #main-content I don't want to give any fix height because content can be long and short but if content is short then it should take minimum height 500px. i need compatibility in all browser. Is thery any w3c valid and cross browser way without using !important because i read !important should not be used In conclusion, don’t use the !important declaration unless you’ve tried everything else first, and keep in mind any drawbacks. If you do use it, it would probably make sense, if possible, to put a comment in your CSS next to any styles that are being overridden, to ensure better code maintainability. I tried to cover everything significant in relation to use of the !important declaration, so please offer comments if you think there’s anything I’ve missed, or if I’ve misstated anything, and I’ll be happy to make any needed corrections. http://www.impressivewebs.com/everything-you-need-to-know-about-the-important-css-declaration/

  • Most efficient way to fetch and output Content with 2-Level Comments?

    - by awegawef
    I have some content with up to 2-levels of replies. I am wondering what the most efficient way to fetch and output the replies. I should note that I am planning on storing the comments with fields content_id and reply_to, where reply_to refers to which comment it is in reply to (if any). Any criticism on this design is welcome. In pseudo-code (ish), my first attempt would be: # in outputting content CONTENT_ID all_comments = fetch all comments where content_id == CONTENT_ID root_comments = filter all_comments with reply_to == None children_comments = filter all_comments with reply_to != None output_comments = list() for each root_comment children = filter children_comments, reply_to == root_comment.id output_coments.append( (root_comment, children) ) send output_comments to template Is this the best way to do this? Thanks in advance. Edit: On second thought, I'll want to preserve date-order on the comments, so I'll have to do this a bit differently, or at least just sort the comments afterward.

  • How to have type hinting in PHP that specifies variable scope inside of a template? (specifically PhpStorm)

    I'm looking for a doc comment that would define the scope/context of the current php template. (similar to @var) Example View Class: <?php class ExampleView { protected $pageTitle; public function __construct($title) { $this->pageTitle = $title; } public function render() { require_once 'template.php'; } } -- <?php // template.php /** @var $this ExampleView */ echo $this->pageTitle; PHPStorm gives an inspection error because the access on $pageTitle is protected. Is there a hint to give scope? Something like: <?php // template.php /** @scope ExampleView */ // <---???? /** @var $this ExampleView */ echo $this->pageTitle;
