  • VBA Access Import Specification strange error

    - by captonssj
    I am trying to import a text file into Access using a saved "Import Specification" in my access database using VBA.

  • Upside down question mark issue

    - by Madhumita
    We have a very strange problem in out application, all of a sudden we started noticing upside down question marks being saved along with other text typed in to the fields on the screen. These upside down question marks were not originally entered by the users and it is unclear where they come from. We are using Oracle 10g with java. And this is happening, even when no data is copied from Microsoft Word

  • What are the differences between these?

    - by Amit Ranjan
    What are the differences between the two queries? SELECT CountryMaster.Id FROM Districts INNER JOIN CountryMaster ON Districts.CountryId = CountryMaster.Id SELECT CountryMaster.Id FROM CountryMaster INNER JOIN Districts ON Districts.CountryId = CountryMaster.Id Please mind the i) Table positions and second ii) On Fields As I know, output will be same. But I want to know, is there any drastic effects of the same if I neglect positions of tables and columns in complex queries or tables having tons of data like thousands and lakhs of rows...

  • Nesting forms in CakePHP

    - by Erik
    I am wondering if there's a way in CakePHP to nest multiple models in a form? What I'm trying to accomplish is to make a form for creating Posts that will also contain fields for adding Images (separate model) that will automatically be connected to the created post. Something similar to Ruby on Rails ** accept_nested_attributes_for**.

  • Splitting tables by field to optimize MySQL?

    - by AK
    Do splitting fields into multiple tables ever yield faster queries? Consider the following two scenarios: Table1 ----------- int PersonID text Value1 float Value2 or Table1 ----------- int PersonID text Value1 Table2 ----------- int PersonID float Value2 If Value1 and Value2 are always being displayed together, I imagine Table1 is always faster because the second schema would require two SELECT statements. But are there any situations where you would choose the second? If the number of records were expected to be really large?

  • Linking two models in a multi-model form

    - by Elliot
    Hey Guys, I have a nested multimodel form right now, using Users and Profiles. Users has_one profile, and Profile belongs_to Users. When the form is submitted, a new user is created, and a new profile is created, but they are not linked (this is the first obvious issue). The user's model has a profile_id row, and the profile's model has a user_id row. Here is the code for the form: <%= form_for(@user, :url => teams_path) do |f| %> <p><%= f.label :email %><br /> <%= f.text_field :email %></p> <p><%= f.label :password %><br /> <%= f.password_field :password %></p> <p><%= f.label :password_confirmation %><br /> <%= f.password_field :password_confirmation %></p> <%= f.hidden_field :role_id, :value => @role.id %></p> <%= f.hidden_field :company_id, :value => current_user.company_id %></p> <%= fields_for @user.profile do |profile_fields| %> <div class="field"> <%= profile_fields.label :first_name %><br /> <%= profile_fields.text_field :first_name %> </div> <div class="field"> <%= profile_fields.label :last_name %><br /> <%= profile_fields.text_field :last_name %> </div> <% end %> <p><%= f.submit "Sign up" %></p> <% end %> A second issue, is even though the username, and password are successfully created through the form for the user model, the hidden fields (role_id & company_id - which are also links to other models) are not created (even though they are part of the model) - the values are successfully shown in the HTML for those fields however. Any help would be great!

  • Changing the highlight color of text in Flash with ActionScript 2.

    - by Zachary Lewis
    I've got several input text fields, and my design requirement is to have gold text on a black background that, when highlighted, is black text on a gold background; however, Flash's default selected text highlight color scheme is white text on a black background and there is no way to change this. Does anyone have any workarounds that are easy to implement and don't require additional classes (the design requests minimal outside classes).

    - by Ed Woodcock
    Ok, I've got a lightbox with a small form (2 fields) in it, inside an UpdatePanel, and I want to close this lightbox (must be done via javascript) when the 'Save' button is pressed. However, there is a need to have a server-side CustomValidator on the page, and I only want to close the lightbox if this returns as valid. Does anyone know a way to trigger javascript (or jQuery) code from a server-side validator?

  • How to access a field's value in an object using reflection

    - by kentcdodds
    My Question: How to overcome an IllegalAccessException to access the value of a an object's field using reflection. Expansion: I'm trying to learn about reflection to make some of my projects more generic. I'm running into an IllegalAccessException when trying to call field.getValue(object) to get the value of that field in that object. I can get the name and type just fine. If I change the declaration from private to public then this works fine. But in an effort to follow the "rules" of encapsulation I don't want to do this. Any help would be greatly appreciated! Thanks! My Code: package main; import java.lang.reflect.Field; public class Tester { public static void main(String args[]) throws Exception { new Tester().reflectionTest(); } public void reflectionTest() throws Exception { Person person = new Person("John Doe", "555-123-4567", "Rover"); Field[] fields = person.getClass().getDeclaredFields(); for (Field field : fields) { System.out.println("Field Name: " + field.getName()); System.out.println("Field Type: " + field.getType()); System.out.println("Field Value: " + field.get(person)); //The line above throws: Exception in thread "main" java.lang.IllegalAccessException: Class main.Tester can not access a member of class main.Tester$Person with modifiers "private final" } } public class Person { private final String name; private final String phoneNumber; private final String dogsName; public Person(String name, String phoneNumber, String dogsName) { this.name = name; this.phoneNumber = phoneNumber; this.dogsName = dogsName; } } } The Output: run: Field Name: name Field Type: class java.lang.String Exception in thread "main" java.lang.IllegalAccessException: Class main.Tester can not access a member of class main.Tester$Person with modifiers "private final" at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:95) at java.lang.reflect.AccessibleObject.slowCheckMemberAccess(AccessibleObject.java:261) at java.lang.reflect.AccessibleObject.checkAccess(AccessibleObject.java:253) at java.lang.reflect.Field.doSecurityCheck(Field.java:983) at java.lang.reflect.Field.getFieldAccessor(Field.java:927) at java.lang.reflect.Field.get(Field.java:372) at main.Tester.reflectionTest(Tester.java:17) at main.Tester.main(Tester.java:8) Java Result: 1 BUILD SUCCESSFUL (total time: 0 seconds)
