• Programmatically import CSV data to Access

  - by FrustratedWithFormsDesigner

  I have an Access database and the source of data comes from generated CSV files. I'd like to have an easy way for the users to simply select the data file and import it. Import should append the existing data to the data already in the data table. Is there a way in Access to create a file selector and import using saved CSV import settings that are already in the file?

• Custom iPad keyboard backspace method last character crash

  - by isaaclimdc

  I'm making a custom UI iPad keyboard app, and I'm doing something similar to this post for the backspace method: custom backspace button crashes iPhone app However, the app will always crash when I "backspace" for the last character in the UITextView. I know -substringToIndex won't work for an empty string, but I tried using a temporary mutable string then using -deleteCharactersInRange, and that crashed it too. I'm guessing the crash is due to me manually setting the -selectedRange property for the text view after deleting a character? But even if I do: textView.selectedRange = NSMakeRange(0, 0); the app will crash. Any ideas?

• Override An Existing Property as a Child form of its return type

  - by Jason

  I apologize if that title is confusing. This question may be a result of lack of coffee and/or sleep, but my mind is not working correctly right now. Anyways, I have an inheritance tree like such (I know the architecture isn't ideal): BaseClass GeneralForm : Inherits BaseClass SpecificForm : Inherits GeneralForm And an object like so: MyItem MySpecificItem : Inherits MyItem I have Items As List (Of MyItem) as a property in BaseClass. I would like for SpecificForm to somehow override Items to return type List (Of MySpecificItem). I feel like this is easy to do, but again, my head is spinning and I can't think straight at the moment. Thank you so much in advance.

• Type parameterization in Scala

  - by horatius83

  So I'm learning Scala at the moment, and I'm trying to create an abstract vector class with a vector-space of 3 (x,y,z coordinates). I'm trying to add two of these vectors together with the following code: package math class Vector3[T](ax:T,ay:T,az:T) { def x = ax def y = ay def z = az override def toString = "<"+x+", "+y+", "+z+">" def add(that: Vector3[T]) = new Vector3(x+that.x, y+that.y, z+that.z) } The problem is I keep getting this error: error: type mismatch; found : T required: String def add(that: Vector3[T]) = new Vector3(x+that.x, y+that.y, z+that.z) I've tried commenting out the "toString" method above, but that doesn't seem to have any effect. Can anyone tell me what I'm doing wrong?

• Wanting a type of grid for a pixel editor

  - by wiggles

  Hi, I am currently trying to develop a basic pixel editor application to build up my programming experience with Java. I am designing it so the user has several colour options on, they click on an option and then they can drag over the cells in the grid and they change colour (like a typical image editor, but with a sort of snap on to each grid cell) Any idea of what Java component, if any, is able to implement this type of grid in Java? I had thought of each cell being a JButton, but this seemed terribly inefficient and I don't think it would be possible to change the colour of each cell(button) with out individually clicking on each one. Any help appreciated.

• UITableView - iPad - Property '' Not Found on Object of type UITableViewCell

  - by user1797508

  I have added a UITableView prototype Cell into a UIView for an iPad application using StoryBoard in Xcode (targeting iOS6). The problem I'm having is that the labels are not being recognized in my viewController when I try to reference them. In my implementation, I have: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"dashboardMessage"; UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } int row = [indexPath row]; cell.messageSender.text = [_matches valueForKey:@"from"]; } The last line is causing an error: Property 'messageSender' Not Found on Object of type UITableViewCell In the cell's header file I have: @interface DashboardMessageCell : UITableViewCell @property (strong, nonatomic) IBOutlet UILabel *messageSender; @property (strong, nonatomic) IBOutlet UILabel *messageDescr; and the header file is imported into the viewController. I'm lost as to what can be causing the issue, any help would be greatly appreciated. Thanks.

• How to debug "The type initializer for 'my class' threw an exception"

  - by JFB

  I am getting the exception: The type initializer for 'my class' threw an exception. in my browser after running my web application. Since this seems to be an error message generated from the view (.aspx), there is no way I can see the stack trace or any log for the source of this error. I have read a bit around the net and one solution to debugging is to throw a TypeInitializationException and then looking at the inner exception to find out what was wrong. How can I do this when I don't know where to surround code with a try/catch ?

• Why is Window.open()'s return type void ?

  - by Salvin Francis

  Doing something like this is perfectly permissible in javascript: var newWindow = window.open(...) However, this does not work in the senario of GWT (I am using 1.5 I dont know about later versions), Window window = Window.open("", "", ""); Throws me a compile time error that the open is a method with a return type as void. Why should it be void ? What if i want to close my popup from the main Window ? how do I get its handle ? I will have to resort to native javascript no doubt but i was just curious so as to why this is so...

• Custom Parser for JQuery Tablesorter

  - by Tim

  I'm using the jQuery Tablesorter and have an issue with the order in which parsers are applied against table columns. I'm adding a custom parser to handle currency of the form $-3.33. $.tablesorter.addParser({ id: "fancyCurrency", is: function(s) { return /^\$[\-]?[0-9,\.]*$/.test(s); }, format: function(s) { s = s.replace(/[$,]/g,''); return $.tablesorter.formatFloat( s ); }, type: "numeric" }); The problem seems to be that the built-in currency parser takes precedence over my custom parser. I could put the parser in the tablesorter code itself (before the currency parser) and it works properly, but this isn't very maintainable. I can't specify the sorter manually using something like: headers: { 3: { sorter: "fancyNumber" }, 11: { sorter: "fancyCurrency" } } since the table columns are generated dynamically from user inputs. I guess one option would be to specify the sorter to use as a css class and use some JQuery to explicitly specify a sorter like this question suggests, but I'd prefer to stick with dynamic detection if possible.

• PHP is not returning me a number type

  - by Tristan

• Custom session state provider needed for DB storage?

  - by subt13

  I know this question is related to many others, but please bear with me. I am trying an experiment to store all information in database tables instead of the ASP.NET session. In ASP.NET 4 one can create a custom provider for session. So, again should I implement a Custom Session-State Provider or should I just disable session (in Web.config)? Thanks! From the comments my question can be misunderstood. Hopefully this tidbit will help clarify: I don't want to store the session in the database. I want to store information in the database that you would typically store in the session. One reason why: I don't want to carry around a session on every page, especially if that page doesn't care about 90 percent of the information in the session

• iphone screen - type of view to use

  - by Fiona

  Hi There everyone... looking for some advice on what type of view can be used to build a screen with the following elements: 2 labels followed by 2 buttons. Then a small table view with 3 rows. Should a UIView be used or a UITableView? I've attempted using a UITableView - however I couldn't add the labels or buttons. So I've now built the view using a UIView. I added the labels and buttons and then a UITableView from the library. However I have no idea how to populate the rows in the table? Any ideas? Regards, Fiona

• Custom URL Schema and UTI

  - by user573259

  I define a Custom URL Schema for my iPhone App http://iphonedevelopertips.com/cocoa/lau…url-scheme.html or a custom UTI (Uniform type identifier) developer.apple.com/library/ios/#documentation/FileManagement/Conceptual/understanding_utis/understand_utis_declare/understand_utis_declare.html%23//apple_ref/doc/uid/TP40001319-CH204-SW1 -- Where is this information stored on the iphone? (I do not mean the Info.plist of the app - here must be a central file for such settings like keychain-2.db for passes and stuff) I got some very confusing behavior of an app that was compiled installed with different settings in the Info.plist for the file type (UTI) association and I would like to check if there is some trash (old settings) left from previous versions.

• Custom DataSource Extender

  - by Brian

  I dream of creating a control which works something like this: <asp:SqlDataSource id="dsFoo" runat="server" ConnectionString="<%$ ConnectionStrings:conn %>" SelectCommandType="StoredProcedure" SelectCommand="cmd_foo"> </asp:SqlDataSource> <Custom:DataViewSource id="dvFoo" runat="server" rowfilter="colid &gt; 10" datasourceid="dsFoo"> </Custom:DataViewSource> I can accomplish the same thing in the code behind by executing cmd_foo, loading the results into a DataTable, then loading them into a DataView with a RowFilter. The goal would be to have multiple DataViews for one DataSource with whatever special filters I wish to apply to the select portion of the DataSource. I could imagine extending this to be more powerful. I tried peaking at this and this but am a bit confused on a few points. Currently, my main issue is being unsure where to grab the output data of the DataSource so I can stick it into a DataTable.

• what is the right 'rails' way to add a link_to a new custom method

  - by jpwynn

  We're adding a new method 'delete_stuff' to the WidgetsController of a scaffolded app. in routes we added match 'widget/delete_stuff/:id' = 'widgets#delete_stuff' I CAN manually create html (GET) links like <a href="/widget/delete_stuff/<% widget.id %>">My Custom Delete Stuff</a> But that's bad on so many levels (uses GET instead of DELETE, doesn't permit a CONFIRM dialog, isnt DRY, etc) Problem is I can't figure out how to use the url helpers for a custom method... trying to do something like this: <% link_to 'DeleteStuff', @widget, :confirm => 'Are you sure?', :method => :delete %> But that just gets ignored when the html is rendered. I'm clearly missing something fundamental on how to use link_to, any help will be appreciated! Cheers, JP

• Unrecognized authentication type when doing an Auth to Exchange from Rails

  - by blakeage

  I'm getting this error when trying to authenticate with Exchange Server from Ruby on Rails: 504 5.7.4 Unrecognized authentication type config.action_mailer.raise_delivery_errors = true config.action_mailer.perform_deliveries = true config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { :address => "x.x.x.x", :port => 25, :user_name => "xxdomain\xxuser", :password => "xxxxxx", :authentication => :login, :enable_starttls_auto => true } I've tried all sorts of combinations of configuration settings, including changing the settings to use "plain" authentication, adding the domain, setting enable_starttls_auto to true, false, and removing it entirely, removing the port. Nothing has worked. Any ideas?

• Performance of: if (OBJECT_INSTANCE is TYPE)

  - by Axonn

  I am working both in C# and ActionScript 3. Both language are type-aware, so you can do verifications such as: if (some_object_instance is SomeClassName_ThatIs_SomeType) I'm doing these kind of verifications in a few places. Might be a dumb question, but I will ask it anyway, and I want answers from both camps, C# and ActionScript: What goes on behind the scenes? Is it Reflection? If is, isn't this a long verification which might degrade performance if done in thousands of loops? And by "degrade performance" I mean, is it more intensive than say if (Math.sqrt(8) > Math.sin(10))

• How do I get my custom requiredif attribute to prevent other attributes from firing

  - by user1757804

  I'm working on an MVC application. I've decorated a property with EqualTo found here: http://dataannotationsextensions.org/EqualTo/Create As well as a custom RequiredIf attribute as suggested here: http://blogs.msdn.com/b/simonince/archive/2011/02/04/conditional-validation-in-asp-net-mvc-3.aspx My issue is that even when the field is supposed to be required and isn't the EqualTo logic is firing. So I get error messages saying the field is required but also that the field doesn't match. If I replace the Requiredif with a regular Required only the Required message will show. What I'm trying to figure out is how the EqualTo logic is prevented when combined with the Required attribute but not prevented when combined with my custom RequiredIf. Any suggestions would be most appreciated, I've been racking my brain most of the day trying to figure out the mvc internals around Required.

• Me As Child Type In General Function

  - by Steven

  I have a MustInherit Parent class with two Child classes which Inherit from the Parent. How can I use (or Cast) Me in a Parent function as the the child type of that instance? EDIT: My actual goal is to be able to serialize (BinaryFormatter.Serialize(Stream, Object)) either of my child classes. However, "repeating the code" in each child "seems" wrong. EDIT2: This is my Serialize function. Where should I implement this function? Copying and pasting to each child doesn't seem right, but casting the parent to a child doesn't seem right either. Public Function Serialize() As Byte() Dim bFmt As New BinaryFormatter() Dim mStr As New MemoryStream() bFmt.Serialize(mStr, Me) Return mStr.ToArray() End Function

• Returning new base class when the parent class shared pointer is the return type

  - by Ben Dol

  Can you have a parent class shared pointer return type of a function and then return a new child class without it being a shared pointer? I'm not sure how shared pointers work in these situations, do they act like a regular pointer? Here is my example: BaseEventPtr Actions::getEvent(const std::string& nodeName) { if(asLowerCaseString(nodeName) == "action") return new ActionEvent(&m_interface); return nullptr; } ActionEvent is the subclass of BaseEvent in this situation. Cheers!

• Searching custom nodes' by field in Drupal?

  - by Airjoe

  Hello- Using Drupal on a project which I made custom node types in using the CCK. I want to be able to search the specific node based on a custom field the node has. So let's say I have this node type Article which has a field "myfield", I want to be able to search for Articles based on the myfield field. I understand the default search module allows for searching of node types using the type:MyNodeType in the search, but I did not see any way to limit which fields are searched. Any tips? Is this something that is going to get crazy? Appreciate the help.

• C++: Template functor cannot deduce reference type

  - by maciekp

  I've got a functor f, which takes a function func and a parameter t of the same type as func. I cannot pass g to f because of compilation error (no matching function for call to f(int&, void (&)(int&)) ). If g would take non-reference parameter g(int s), compilation finishes. Or if I manually specify template parameter f(i, g), compilation also finishes. template<typename T> void f(T t, void (*func)(T)) {} void g(int& s) {} int main(int, char*[]) { int i = 7; f(i, g); // compilation error here return 0; } How can I get deduction to work?
