Answer by Seth Spearman for MS Access tabbed form multiple OnCurrent firings

I believe the proper way to do this is to not dynamically change the rowsource of the combobox. Instead, set the rowsource to a query using the query designer and have the query read the value from the "main form" just as is shown in your sample code...Forms![products main form]!ProductNumber.

Then I would trigger the refresh of the combo box using the MAIN FORMs AfterUpdate event. It will be something like MainForm!MySubForm.Form("mycombobox").requery. (I may not have that syntax exactly right...my access syntax is rusty.)

BTW, I don't like my own answer. The reason is that you are hard-coding a dependency between the subform and its parent. That might be fine if you will NEVER use that subform anywhere else. To get around this some Access Developers use a hidden form that has textboxes that you set from the Main Form's After Update event. Then the query is updated to refer to the the hidden form's textbox that you created for this form.

There are other ways to do this, too (public functions for example). But sorry, that is not really what you were asking for. My first method will work. But first time you need to re-use that subform you will need to refactor and the hidden form solution works pretty well.

Does SQL short-circuit the evaluation of an OR in the WHERE CLAUSE?

Looking at other questions here on SO and google seems to indicate MS Sql Server does not guarantee to short circuit the expressions in the WHERE clause.

Does that mean that a WHERE expression like this this one cannot be trusted to work...?

... WHERE (@include_voided = 1 OR mytable.void = 0) AND ... 

I frequently use this kind of expression in my stored procedures. Having researched short-circuiting for another reason I am now wondering if this should be replaced with ...

... WHERE mytable.void = case when @include_voided=1 then mytable.void else 0 END

...as all of the articles seem to indicate that CASE statements are the only ones guaranteed to short-circuit.

I am hoping that the first expression is fine just because it is more readable and easier to type.

How to add an SQL Table to a Microsoft Access application

I was having a weird time getting a new Sql Table to work properly in an Access application.  The problem is that this app has not had a new table added for several years so I kept chasing red herrings.  Ultimately here are the steps that work for me…

 

WHAT TO DO TO ADD AN A TABLE TO Sql

1.  Be sure to NOT forget to set the permissions on the table like this...
    GRANT INSERT, UPDATE, DELETE, SELECT, VIEW DEFINITION ON <NEW_TABLE_NAME> TO MYDB  Ultimately this was the step I forgot.
    
    DO NOT link the table to Access until the permissions have been set.

2.  When adding the table as a new linked table into  the app, use a FILE DSN.  Using a System DSN may have contributed to the issue as well.  Click the Save Password checkbox when linking it in.
   
3.  Remove the dbo_ from the front of the table name in Access.

4.  Your Access app needs a RefreshTableLinks process as described all over the place (just google refresh sql table links in msaccess).  Run that after adding the table.  Here is an example.

Awesome SQL 2005 script for generating Insert statements of your data.

In the past when I needed a way to generate INSERT STATEMENTS for database rows I have looked to the excellent script of Narayana Vyas Kondreddi located at the following URL.  (The INSERT script is one of many fabulous scripts on this page.) http://vyaskn.tripod.com/code.htm#inserts This web page links to the following text page that has the actually script. http://vyaskn.tripod.com/code/generate_inserts_2005.txt However, today when I needed a fresh copy the website was returning a 403 error message.  I was able to find it in the google cache but it was rather a pain.   So, for posterity, I include the script  
SET NOCOUNT ON

Purpose:	To generate INSERT statements from existing data. 
		These INSERTS can be executed to regenerate the data at some other location.
		This procedure is also useful to create a database setup, where in you can 
		script your data along with your table definitions.

NOTE:		This procedure may not work with tables with too many columns.
		Results can be unpredictable with huge text columns or SQL Server 2000's sql_variant data types
		Whenever possible, Use @include_column_list parameter to ommit column list in the INSERT statement, for better results
		IMPORTANT: This procedure is not tested with internation data (Extended characters or Unicode). If needed
		you might want to convert the datatypes of character variables in this procedure to their respective unicode counterparts
		like nchar and nvarchar

		ALSO NOTE THAT THIS PROCEDURE IS NOT UPDATED TO WORK WITH NEW DATA TYPES INTRODUCED IN SQL SERVER 2005 / YUKON
		

Example 1:	To generate INSERT statements for table 'titles':
		
		EXEC sp_generate_inserts 'titles'

Example 2: 	To ommit the column list in the INSERT statement: (Column list is included by default)
		IMPORTANT: If you have too many columns, you are advised to ommit column list, as shown below,
		to avoid erroneous results
		
		EXEC sp_generate_inserts 'titles', @include_column_list = 0

Example 3:	To generate INSERT statements for 'titlesCopy' table from 'titles' table:

		EXEC sp_generate_inserts 'titles', 'titlesCopy'

Example 4:	To generate INSERT statements for 'titles' table for only those titles 
		which contain the word 'Computer' in them:
		NOTE: Do not complicate the FROM or WHERE clause here. It's assumed that you are good with T-SQL if you are using this parameter

		EXEC sp_generate_inserts 'titles', @from = "from titles where title like '%Computer%'"

Example 5: 	To specify that you want to include TIMESTAMP column's data as well in the INSERT statement:
		(By default TIMESTAMP column's data is not scripted)

		EXEC sp_generate_inserts 'titles', @include_timestamp = 1

Example 6:	To print the debug information:
  
		EXEC sp_generate_inserts 'titles', @debug_mode = 1

Example 7: 	If you are not the owner of the table, use @owner parameter to specify the owner name
		To use this option, you must have SELECT permissions on that table

		EXEC sp_generate_inserts Nickstable, @owner = 'Nick'

Example 8: 	To generate INSERT statements for the rest of the columns excluding images
		When using this otion, DO NOT set @include_column_list parameter to 0.

		EXEC sp_generate_inserts imgtable, @ommit_images = 1

Example 9: 	To generate INSERT statements excluding (ommiting) IDENTITY columns:
		(By default IDENTITY columns are included in the INSERT statement)

		EXEC sp_generate_inserts mytable, @ommit_identity = 1

Example 10: 	To generate INSERT statements for the TOP 10 rows in the table:
		
		EXEC sp_generate_inserts mytable, @top = 10

Example 11: 	To generate INSERT statements with only those columns you want:
		
		EXEC sp_generate_inserts titles, @cols_to_include = "'title','title_id','au_id'"

Example 12: 	To generate INSERT statements by omitting certain columns:
		
		EXEC sp_generate_inserts titles, @cols_to_exclude = "'title','title_id','au_id'"

Example 13:	To avoid checking the foreign key constraints while loading data with INSERT statements:
		
		EXEC sp_generate_inserts titles, @disable_constraints = 1

Example 14: 	To exclude computed columns from the INSERT statement:
		EXEC sp_generate_inserts MyTable, @ommit_computed_cols = 1

Writing store local and sync remote applications with .NET

Found this... Depending on how much "Control" you want to have within your sync, it might be best to use an existing framework that already handles this for you. Some great suggestions would be: Microsoft Sync Framework - http://msdn.microsoft.com/en-us/sync/bb736753.aspx Azure Mobile Services (Offline Sync) - Great video of what is coming soon/in preview: http://channel9.msdn.com/Events/Build/2014/3-623 iFacr - http://ifactr.com/platform/data-sync-engine Bidirectional syncs can be quite tough to make and manage, and in my opinion it's better to let some of these frameworks handle the heavy lifting for you. Azure Mobile Services have some great things on the horizon that are really fun to play with. You can get a small introduction from a blog post I wrote here: http://www.jon-douglas.com/2014/04/to-the-cloud/ I personally prefer having the control on my backend(Web API), and thus I create a ASP.NET Web API for my Azure Mobile Service, and let the data structures that Azure Mobile Services provide to obtain my bidirectional sync. In that video I linked above, he somewhat goes over how that is accomplished and how it works when a device is offline.   Found here... http://forums.xamarin.com/discussion/15900/data-sync-from-sql-db-to-the-application-local-storage

Creating a yeoman generator

  1. Create a directory.  Open a node command prompt to that directory.
  2. Create a node project...
    npm init
  3. Install the base yeoman packages...
    npm install yeoman-generator --save (save adds dependencies to our node project).
  4. Add a folder called "app".
  5. In that folder add a file called "index.js".
  6. put your generator code in the index.js file... like this...
    'use strict'

    var generators = require('yeoman-generator');

    module.exports = generators.Base.extend({
    method1: function(){
    this.log('Hello, World!');
    }
    });

  7. Create a symlink to your current directory for npm using this command...
    npm link (this enables the running of the generator)
