  • Method of getting text on a windows form ( unmanaged C++ project )

    - by Donovan
    I'm in the process of learning C++. I've created a boilerplate Win32 app within VC++ 2008. I've studied through the code and am ready do do a bit of experimenting. I thought it would be cool to print all the windows messages received in the message loop to the form created via the boilerplate code. I for the life of me, can't figure out the method of getting text onto that form. I can't seem to identify and named object that I can use to reference that damn form. The best I can figure is I need to use the handle to reference the form somehow. Still, even if I did know how to reference the form, I'm not sure I know how I would create a label to display the text. Anyway, if someone could just point out what methodology I need to learn to make this happen it would be much appreciated. Thanks, Donovan

  • Migrate Data and Schema from MySQL to MSSQL

    - by colithium
    Are there any free solutions for automatically migrating a database from MySQL to MSSQL Server that "just works"? I've been attempting this simple (at least I thought so) task all day now. I've tried: MSSQL Server Management Studio's Import Data feature Create an empty database Tasks - Import Data... .NET Framework Data Provider for Odbc Valid DSN (verified it connects) Copy data from one or more tables or views Check 1 VERY simple table Click Preview Get Error: The preview data could not be retrieved. ADDITIONAL INFORMATION: ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.1.45-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"table_name"' at line 1 (myodbc5.dll) A similar error occurs if I go through the rest of the wizard and perform the operation. The failed step is "Setting Source Connection" the error refers to retrieving column information and then lists the above error. It can retrieve column information just fine when I modify column mappings so I really don't know what the issue is. I've also tried getting various MySql tools to output ddl statements that MSSQL understand but haven't succeeded. I've tried with MySQL v5.1.11 to SQL Server 2005 and with MySQL v5.1.45 to SQL Server 2008 (with ODBC drivers 3.51.27.00 and 5.01.06.00 respectively)

  • What is the maximum number of controls that a VBA form can hold?

    - by Lunatik
    I'm currently building an Excel 2003 app that requires a horribly complex form and am worried about limitations on the number of controls. It currently has 154 controls (counted using Me.Controls.Count - this should be accurate, right?) but is probably only about a third complete. The workflow really fits a single form, but I guess I can split it up if I really have to. I see evidence in a Google search that VB6 (this usually includes VBA) has a hard limit of 254 controls in a form. However, I created a dummy form with well over 1200 controls which still loaded and appeared to work just fine. I did get some 'out of memory' errors when trying to add specific combinations of controls though, say 800 buttons and 150 labels, leading me to think that any limit might be affected by the memory requirements of each type of control. Does anyone have any information that might help ensure that I or, more importantly, other users with differing environments don't run into any memory issues with such a large form?

  • How can I organize many results in a selectbox using php?

    - by zeckdude
    I have a select box that is part of a form. It is currently querying the addresses table and displaying the addresses into the select box. I plan on having up to 100 addresses. I'm looking for a solution where I can show all the states if the user clicks on the select box. Then if the user hovers over a state it will show all the addresses for that specific state. Then if the user clicks on an address, it will show that as the picked option in the select box. This is like a dropdown menu within a select box. Does anyone know where I can find a solution as this?

  • jquery binding multiple events, and pass data

    - by mkoryak
    I know we can have this in 1.4: $("a").bind({ click : clickFn, mouseover: mouseFn }); and that is nice and i would like to use it, but it seems like there is no way to pass extra data to events bound this way, it needs to be done the 'old way': $("a").bind("click", {"some":"data"}, clickFn); Question: how can i pass the extra data to my event call backs and bind multiple events in a single bind at the same time?

  • Which features do html form elements miss

    - by Bakhtiyor
    I just wondered and wanted to gather together in one place all missing features of our beloved html form elements. One example could be missing of horizontal scrollbar in a listbox. But I am sure there are a lot of features we would like to see in our form elements by default. I order to be clear let's only take into account HTML4, because with HTML5 there are a lot of things haven't been finished yet. One missing feature per answer please. Thank you.

  • Rails - Help scoring an online quiz in RoR

    - by ChrisWesAllen
    I'm trying to grade a quiz application I would like to make. I have a questions model with and ask(the actual question), 4 choices(a-d), and a correct answer(string). In the view I have the 4 question being diplayed then the correct answer choice (This is just a test for functionality) and then I created a text_field to accept the users answer choice and a button to refresh the index action which has the scoring logic, for now.. --Do I need to put the text_field within a form_tag? <p>1. <%= h @question.q1 %></p> <p>2. <%= h @question.q2 %></p> <p>3. <%= h @question.q3 %></p> <p>4. <%= h @question.q4 %></p> <p>Answer: <%= h @question.correct %></p> <%= text_field_tag :choice, params[:choice] %> <%= button_to "Grade", {:controller => 'site', :action => "index"} %> <p> <%= @answer %></p> Heres the index controller action def index @question = Question.find(1) if @question.correct == params[:choice] @answer = 'right' else @answer = 'wrong' end end Its not really working. The textfield is supposed to take a letter choice like 'a' or 'c' and compare it with the correct answer in the database. I would love this to work by radiobuttons, but I'm a newbie to rails so I thought I'd take baby steps. So if anyone can help me with how to fix this by string, or preferably by radiobuttons, I'd really appreciate it.

  • Updating nested attributes causes duplicate entries

    - by params_noob
    I have a has_many and belongs_to relationship between Job and Address. When I try to update Job and Address in the same form, it updates job but creates a duplicate entry for Address. Am I missing something here? The Edit and Update Actions from Jobs: def edit @job = Job.find(params[:id]) end def update @job = Job.find(params[:id]) if @job.update_attributes(job_params) flash[:success] = "Job Updated" redirect_to current_user else render 'edit' end end The edit form: <h1>Edit Job Information</h1> <div class="row"> <div class="span6 offset3"> <%= form_for(@job) do |f| %> <%= render 'shared/error_messages' %> <%= f.label :recipient %> <%= f.text_field :recipient %> <%= f.label :age %> <%= f.text_field :age %> <%= f.label :gender %> <%= f.text_field :gender %> <%= f.label :ethnicity %> <%= f.text_field :ethnicity %> <%= f.label :height %> <%= f.text_field :height %> <%= f.label :weight %> <%= f.text_field :weight %> <%= f.label :hair %> <%= f.text_field :hair %> <%= f.label :eyes %> <%= f.text_field :eyes %> <%= f.label :other_info %> <%= f.text_field :other_info %> <h3> Address Information </h3> <%= f.fields_for :addresses do |address| %> <%= address.label :label, "Label" %> <%= address.text_field :label %> <%= address.label :addy, "Address" %> <%= address.text_field :addy %> <%= address.label :apt, "Apt/Suite/etc" %> <%= address.text_field :apt %> <%= address.label :city, "City" %> <%= address.text_field :city %> <%= address.label :state, "State" %> <%= address.text_field :state %> <%= address.label :zip, "Zip code" %> <%= address.text_field :zip %> <% end %> <%= f.label :instructions, "Service Instructions" %> <%= f.text_field :instructions %> <%= check_box_tag(:rush) %> <%= label_tag(:rush, "Rush?") %> <%= f.submit "Update Job", class: "btn btn-large btn-primary" %> <% end %> </div> </div>

  • Arbitrary Form Processing with Drupal

    - by Aaron
    I am writing a module for my organization to cache XML feeds to static files to an arbitrary place on our webserver. I am new at Drupal development, and would like to know if I am approaching this the right way. Basically I: Expose a url via the menu hook, where a user can enter in a an output directory on the webserver and press the "dump" button and then have PHP go to drupal and get the feed xml. I don't need help with that functionality, because I actually have a prototype working in Python (outside of Drupal).. Provide a callback for the form where I can do my logic, using the form parameters. Here's the menu hook: function ncbi_cache_files_menu() { $items = array(); $items['admin/content/ncbi_cache_files'] = array( 'title' => 'NCBI Cache File Module', 'description' => 'Cache Guide static content to files', 'page callback' => 'drupal_get_form', 'page arguments' => array( 'ncbi_cache_files_show_submit'), 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } I generate the form in: function ncbi_cache_files_show_submit() { $DEFAULT_OUT = 'http://myorg/foo'; $form[ 'ncbi_cache_files' ] = array( '#type' => 'textfield', '#title' => t('Output Directory'), '#description' => t('Where you want the static files to be dumped. This should be a directory that www has write access to, and should be accessible from the foo server'), '#default_value' => t( $DEFAULT_OUT ), '#size' => strlen( $DEFAULT_OUT ) + 5, ); $form['dump'] = array( '#type' => 'submit', '#value' => 'Dump', '#submit' => array( 'ncbi_cache_files_dump'), ); return system_settings_form( $form ); } Then the functionality is in the callback: function ncbi_cache_files_dump( $p, $q) { //dpm( get_defined_vars() ); $outdir = $p['ncbi_cache_files']['#post']['ncbi_cache_files']; drupal_set_message('outdir: ' . $outdir ); } The question: Is this a decent way of processing an arbitrary form in Drupal? I not really need to listen for any drupal hooks, because I am basically just doing some URL and file processing. What are those arguments that I'm getting in the callback ($q)? That's the form array I guess, with the post values? Is this the best way to get the form parameters to work on? Thanks for any advice.

  • IE6 and IE7 Input padding CSS

    - by Podlsk
    I have input boxes with a height of 25 pixels. In Firefox, Safari and IE8 automatically vertically align the text of it in the middle correctly. However in IE6 and IE7 the text is aligned to the top. How may I resolve this? Adding padding-top increased the total height of the input as I have explicitly declared its height. I don't wish to use browser specific CSS. Thanks.

  • Nested Select in Rails

    - by James
    I am working on a Rails application which uses categories for items. My category model is self-joined so that categories can be nested: class Category < ActiveRecord::Base has_many :items # Self Join (categories can have subcategories) has_many :subcategories, :class_name => "Category", :foreign_key => "parent_id" belongs_to :parent, :class_name => "Category" ... end I have a form which allows a user to create an item which currently lists all categories in a select, but they are all listed together: <%= f.label :category_id %> <%= select :item, :category_id, Category.all.collect {|c| [ c.title, c.id ]} %> So the select looks something like this: Category1 Category2 Category3BelongsTo2 Category4BelongsTo1 But what I want is: Category1 - Category4BelongsTo1 Category2 - Category3BelongsTo2 Is there a helper for this (which would be awesome!)? If not, how could I accomplish this? Thanks!

  • Is a "Confirm Email" input good practice when user changes email address?

    - by dibson
    My organization has a form to allow users to update their email address with us. It's suggested that we have two input boxes for email: the second as an email confirmation. I always copy/paste my email address when faced with the confirmation. I'm assuming most of our users are not so savvy. Regardless, is this considered a good practice? I can't stand it personally, but I also realize it probably isn't meant for me. If someone screws up their email, they can't login, and they must call to sort things out.

  • RAII: Initializing data member in const method

    - by Thomas Matthews
    In RAII, resources are not initialized until they are accessed. However, many access methods are declared constant. I need to call a mutable (non-const) function to initialize a data member. Example: Loading from a data base struct MyClass { int get_value(void) const; private: void load_from_database(void); // Loads the data member from database. int m_value; }; int MyClass :: get_value(void) const { static bool value_initialized(false); if (!value_initialized) { // The compiler complains about this call because // the method is non-const and called from a const // method. load_from_database(); } return m_value; } My primitive solution is to declare the data member as mutable. I would rather not do this, because it suggests that other methods can change the member. How would I cast the load_from_database() statement to get rid of the compiler errors?

  • Problem Passing Variable to Submit Form in Firefox

    - by George
    In the following example, I have a link that sends a variable to a function which checks if the variable is true and, if so, submits a form on the page. This has been tested and works in IE, Safari, and Chrome, but not Firefox. Trying to figure out what's wrong in Firefox. The function which checks 'action' and then submits form 'login' : function submit(action) { if (action == "submit") { document.login.submit(); } } Link to pass action variable and submit form: <a href="javascript:submit('submit');">SEND FORM</a> When I remove the check and just have the following, it works fine in Firefox: function submit() { document.login.submit(); } <a href="javascript:submit();">SEND FORM</a>

  • Benefit of outputting JSON as opposed to plain HTML

    - by Franco
    Hey guys, Just wondering which is best here. I want to output data from a table in my DB then put a lot of this data into a html table on the fly on my page. Im working with Java on the server side. Basically I pull the results form the DB and have the raw data..just what next? There is a chance I may want to take data from multiple tables in order to combine it into one table for my site. I retrieve the results of the query from the DB, now do i create a text from it in the form of json which i can parse as json using jquery upon the return of the object to my browser?(kind of a sub question of this question: Is just using a stringbuilder the correct way to make a json object to output?) Or.. Should i build the HTML as a string and output that to the browser instead? Which is better and why? Thanks in advance!

  • How to prepare data for display on a silverlight chart using WCF RIA Services + Entity Framework

    - by Banford
    I've used WCF RIA services with Entity Framework to build a simple application which can display and updates data about school courses. This was done by following the Microsoft tutorials. Now I would like to have a chart which shows a count for how many courses are on a key stage. Example: Key Stage 3 - 20 courses Key Stage 4 - 32 courses Key Stage 5 - 12 courses Displayed on any form of chart. I have no problem binding data to the chart in XAML. My problem is that I do not know how to correct way of getting the data into that format. The generated CRUD methods are basic. I have a few thoughts about possible ways, but don't know which is correct, they are: Create a View in SQL server and map this to a separate Entity in the Entity Data Model. Generating new CRUD methods for this automatically. Customise the read method in the existing DomainService using .Select() .Distinct() etc. Don't know this syntax very well labda expressions/LINQ??? what is it? Any good quickstarts on it? Create a new class to store only the data required and create a read method for it. Tried this but didn't know how to make it work without a matching entity in the entity model. Something I am not aware of. I'm very new to this and struggling with the concepts so if there are useful blogs or documentation I've missed feel free to point me towards them. But I'm unsure of the terminology to use in my searches at the moment.

  • Sharing [config] data across modules,functions

    - by williamstw
    I have some configuration data in a config file that I read off disk when the app starts. I need to make that configuration data available to other functions/modules in the application. I started down the path of looking into ets/mnesia to store the data on startup to make it shared among all processes, but then my inner voice cautioned me that there must be a more functional, erlang-y way to do this. The only alternate approach I've come up with so far is setting up a module that has an actor loop that reads the data on startup and responds to messages like {Key, From} and responds by From ! {ok,Value}. Then, I gave up and decided to ask... Thanks, --tim
