MS Access : Migrating “hidden” indexes on fields with Foreign Key constraints, Part 2
In this video, the 2nd of 2, I explore in more detail, what these indexes appear to me to be, why they are on fields involved in a relationship with Referential Integrity enforced, and why SSMA doesn't, and shouldn't, migrate them as indexes.

MS Access : Identify “hidden” indexes on fields with Foreign Key constraints, Part 1
Did you know that Access creates indexes on fields designated as Foreign Keys whether you ask for those indexes or not? You probably didn't know about them because those indexes do not appear in the Index property sheet for tables. In this video, you'll learn how to expose hidden indexes on a table and why you might want to do that.

My (somewhat belated) Return to Classic Client Server Design for PowerApps applications
PowerApps offers a lot of tools to filter, search and sort records, some of which are not natively available in Access. It turns out, however, that good design is the same in both environments. Ignore that at your own peril. Let my experience be a lesson.

The Most Important PowerApps Flow for Access Developers to Know
Access developers have always had the power of reusable VBA Functions and Subroutines in their database applications. Adding PowerApps to our toolkits can seem like a step backwards when we learn that reusability is not quite so easy. On the other hand, Access developers who use SQL Server know that SQL Server has its own powerful tools: Stored Procedures and Functions. The brilliant part is that one simple pattern for PowerApps flows can bring all of that SQL Server processing strength into our Power Apps applications. I'll show you how. ERRATA: I noticed that around the 8 minute mark, I referred to "creating a view". I should have referred to , "creating a flow" to invoke the Stored Procedure. The error survived both recording and editing of the video. 😳 Link to Shane Young's Video on creating PowerApps flows. https://youtu.be/vpjf5mD-COs?list=TLPQMDIwMTIwMjRHlyqQyynJ9A

Reusable PowerApps Code-- Maybe Not Your Typical VBA Function, but It Works!
Access developers have always had the power of reusable VBA Functions and Subroutines in their database applications. Adding PowerApps to our toolkits can seem like a step backwards when we learn that reusability is not quite so easy. However, there is a way to create reusable code which has at least some of the advantages that offers. This video shows you how.

Wanna Feed Your Need for Speed? Named Formulas instead of Collections for PowerApps
How fast does your PowerApps application load and start? Not fast enough? Try replacing an overloaded StartUp with Named Formulas where possible. You'll be glad you did. In PowerApps, app level Formulas perform most of those same roles and enhance a PowerApps application in the same ways. I show you how it works, including tips on off-loading filtering and sorting to the database behind the app. There are trade-offs, such as flirting with the Delegation limit for large record sources. Overall, the benefits outweigh the risks. And the whole app is easier to manage into the bargain. Link to Shane Young's video that inspired this revision: https://youtu.be/jc2DquMS7qM

Can I load 300,000 Records into a PowerApps Application? Yes! But check out what happened next!
PowerApps has a delegation limit of 500 to 2000 records at a time. What happens, then, if your record source contains 10s of thousands or even 100s of thousands of records? Can you put them in a collection and avoid that limit? Let's find out. Links to downloads: https://www.gpcdata.com/downloads/Employees2K7.zip https://www.gpcdata.com/downloads/Employeesbacpac.zip

Should I use Collections, Named Formulas or Tables for Gallery Items? Here's My Choice, and Why
After comparing speed and usability, I came to a conclusion. In this video I offer some guidelines to help you choose between Collections, Named Formulas and Tables for Gallery Items. Let me know in the comments if you agree or disagree. This is a companion video to "Load 300,000 Records into a PowerApps Application?"

Let users know how many records are in the fully populated gallery without scrolling to the end.
Let your users know how many total records are going to be loaded into a gallery by querying the underlying record source. By default, galleries load records in groups of 100, so the user is left wondering, "Is that everything?" When Delegation Limits also come into play, the problem can be even more difficult. I solved the dilemma, except for one minor detail, with a PowerApps flow and a Stored Procedure in SQL Server. Here's the SQL from the Stored Proc. The rest of the code is in the video. USE [NameOfYourDatabaseGoesHere] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE OR ALTER PROCEDURE [dbo].[RecordCount] @SearchTerm varchar(10) = '' AS BEGIN DECLARE @Recordcount int SELECT @Recordcount = count(*) FROM dbo.Employees WHERE LastName like '%' + @SearchTerm + '%' OR FirstName like '%' + @SearchTerm + '%' RETURN @Recordcount END GO

App Variables and Application Bias
App variables, or Global variables, make it possible to pass data between screens in a multi-screen application. There are good ways to do that, and better ways to do that. In part 8, you learn how to do it more efficiently. Application Bias is the subconscious belief that once you've mastered one development environment, those skills automatically enable you to work in a new environment. While there are significant similarities, it's wise to be alert to the subtle differences as well. I explain how I fell into that bias and how I learned to overcome it.
Video Run Time: 12:57 Date Published: 2023-10-23

Context Variables or App Variables
A good naming convention helps keep variables sorted out. In PowerApps, variables can have App-wide, or global scope, or they can have screen level, or context scope. Using them correctly requires understanding the difference and when to use each. UpdateContext() creates local, or screen level variables. Set() creates App-wide, or global variables. My new naming convention helps me keep that straight. In Part 7 you learn the difference between the two and see an example of why it matters.

Patch Records in the source table - Lessons from unbound Access forms
Bound or unbound interface objects in PowerApps? It's axiomatic that bound forms are the most effective way to manage data in Access. Is that also true in PowerApps? I argue that it's not. In Part 6 you review the Patch command, which allows you to append or update records in the underlying data source in a powerful, flexible way that I find preferable to trying to use Forms.
Video Run Time: 11:27 Date Published: 2023-10-18

Appropriate Roles for List and Detail Views in the PowerApps Interface
Deploy a smart interface: separate roles for List and Detail views. In Part 5 you review the most effective and performant way to display data to users and also offer them a way to edit that data as required. The initial list of records, or items, is read-only and formatted for presentation. To modify one of those items, a good interface also provides a detail screen in which all data points are open for edits. Compare this interface in a browser-based app to those you've created in Access. List views are read-only for quicker display. Detail views are editable.

Leverage the Power of SQL Server Views to streamline data logic problems
Leveraging the greater power of the SQL Server database engine In Part 4 you learn how to use the greater data logic and data manipulation power of the SQL Server engine to shape data for display in an interface. Although this example is relatively simple, it illustrates the principle that you should try to use the SQL Server (or other database engine) to perform data logic tasks whenever possible. Save the interface resources for tasks related to displaying the information. I explain the design of the view which is used to populate a collection in the PowerApps application and explain why it's a better solution than doing the data lookup and concatenation directly in the interface.

Display Many-to-Many Relationships in PowerApps Galleries: Books and their Authors
Displaying related records in a gallery and sub-galleries In Part 3, you learn how to recognize many-to-many relationships in a relational database. You also learn how to display the related records in the PowerApps interface. The records in one table populate a gallery. The records in the related table populate embedded sub-galleries in that main gallery. I show you how to set up the sub-galleries and return the records needed to populate them. I also show you how to create in-memory, temporary tables, or Collections, in PowerApps to minimize the number of times your application has to ask the database for those records. This technique is especially valuable for recordsets larger than the delegation limit in PowerApps.

PowerApps 4 Access Devs --10, 000 Records -- 2nd Look
In a second look at the process of loading 10,000 records into a PowerApps application, we consider the positive impact on performance increasing data row limits from 500 to 2,000 records and the negative impact on performance of the presence of Lookup fields in a gallery. We introduce the Patch() function to add add new records to a table. We look at the use of the PowerApps StartUp event to set the value of global variables. A list of resources used for this application is available in the description of the initial video.

PowerApps 4 Access Devs 10,000 Records -- Oops!
I identified and corrected a logic bug (wrong math approach) which appeared during repeated testing. Funny how that works, eh? I also changed the workflow for the application after reconsidering the impact on performance that comes from repeatedly (and probably unnecessarily) re-populating a large collection. Note: On my smart phone, startup takes as little as two or three seconds. I think the difference is partly due to the heavy processing load in the development environment which is also competing with recording software for resources.

PowerApps 4 Access Devs - Load 10,000 Records
10,000 Records in a Database Application? Really? Access developers work with large recordsets, sometimes hundreds of thousands of records, so the idea of being limited to 500 (or even 2,000) seems unworkable. Fear not, there is a way to load thousands and thousands of records into your PowerApps application. This video shows you how. It also shows you why that's actually not a good idea.

Reconciling Business Rules and Normalization
Normalization, or or the rules for creating a set of relational tables, is only part of the process. You also need to reconcile good table design with the business requirements that govern your database application. There may be more than one way to go, and determining which way will best support the business rules is a big part of doing a good job.

One-to-Many or Many-to-Many -- and Why Part II
Microsft Access Relational Databases capture information about relationships between two or more entities: People and Email Addresses, Classes and Students, Invoices and Line Items on the Invoices, Meals and Food Items in the Meals. Some of those relationships are one-to-many. Some of those relationships are many-to-many. In this video, you'll learn about both types, and you'll see how to create appropriate related tables for each type

GPC's Fully Functional Sample Access Database Applications

"Contains" Search in Multiple Fields

*New -- May, 10, 2020
A frequent request in Access forums is a search function that works like the "contains" searches common in web sites. Instead of an exact match, or a match beginning with the first letter of a word, a "contains" search returns all instances of a field where the search term occurs anywhere in the string.
For example, a "contains" search for "gus" would return names containing those three letters: First names like "Augustus" or "Gustav" as well as Last names like "Anthrogus" and so on.
I achieve this result by using TempVars to filter on multiple fields. This demo shows you how to implement the query and set the tempvars.
*This version supports both 32 bit and 64 bit Access.*

Animated GIF for "Please Wait" Message

*New -- May, 12, 2020

Sometimes I learn something while trying to answer questions on an online Access forum. This was one such occasion. I really appreciate the poster's persistence in pushing me to a solution.
The original request was to display an animated GIF on a form in Access. My first thought was, unfortunately, "That's a bad idea." However, after an exchange of ideas with the original poster, I realized this could be a pretty good idea and one worth pursuing. The result is this demo.
An animated GIF can be displayed in a web browswer control. That means the image file must be stored in a location to which all copies of the Access Front End accdb have permissions. Or copies of it can be saved to the same folder where that Access FE accdb resides on each user's computer. Either way, the animated GIF can be displayed at the beginning of a long-running process and hidden again when that process completes.
I will leave it to you to try out other approaches to implementing this feature, such as dynamically loading different animated GIFs for different processes, or changing the size and location of the web browser control to maximize use of form spacing.
*This version supports both 32 bit and 64 bit Access.*

Cancel Report on No Data without Error Message

*New --May 2, 2020
*Validated for 64 bit version of MS Access --May 4, 2020
When a report opens without data, you can use the On No Data event to cancel the report and issue custom messages or responses.
However that cancellation will send error 2501 back to the event which called the "Report Open" event. That means you must also handle that returned error from the calling procedure in the calling form as well.
This demo illustrates how to handle it.

Calls & Meetings--Contact Manager Database

*Updated -- April 14 2020

Contact Manager is a completely revised and updated version of an application I built for a client several years ago. It tracks:

  • Companies with whom you have contacts.
  • Individual Contacts at those companies, with contact information.
  • Calls to your contacts.
  • Meetings with your contacts.
  • In this version, many outdated methods were replaced with more flexible methods, primarily based on TempVars and IIF() functions to eliminate the need for dynamic sql or hard-coded forms references. Also, some unnecessary restrictions on data entry were modified or removed.
    You might use this basic version as a "starter" for your own purposes. Like all of my demos, it can be expanded. Feel free to make any changes needed to suit your situation. However, note that I can't be responsible for any use you make of the application.
    Reports were improved and simplified.
    **Compatible with 32 bit and 64 bit Access.

    Create a Dynamic Menu

    *Updated -- March 18, 2021
    A Proof of Concept I created in 2004 for an article in the old Smart Access magazine. The Splash form re-creates a set of command buttons on the main menu form each time the mdb or accdb is opened. Like the Ribbon that was introduced a few years later, the menu items are stored in a table from which the menu is re-built.
    *Added accdb compatible with 32 bit Access and 64 bit Access. Updated some code.

    Create a Membership Directory with images of each person

    *New -- February, 2021
    Including images in forms and reports in Access requires very little design and programming beyond adding image control(s) and binding the appropriate image to them. This can be done either by making the location of the image file the value in a field in a table, or by calling the images up dynamically. This demo illustrates the latter approach.
    Although Access does support storing images internally, that causes file bloat. Therefore, storing images externally and linking to them is highly recommended. Therefore, this demo uses a subfolder to store images selected and used for one or more members.
    Originally designed from a "rescue" project I completed for a friend, I recently dusted it off and cleaned it up for this demo.
    Download and unZIP the sample files. Make sure the images subfolder is created during that process.

    GPC's Work Tracking Demo

    *Updated -- October 29, 2016
    Download the full, working accdb or mdb version of GPC's Work Tracking Demo, with the VBA that makes it work. I originally built this tool for myself, to track time and efforts on projects for my clients. Over time I expanded it to include some rudimentary Project Management features,such as defining the deliverables for a project, scheduling major milestones, and prioritizing tasks. It's a little more than a timesheet and a little less than a project management tool. You may either use Work Tracking as-is or modify it to suit your needs.The current backend DB for my working version in on SQL Azure, but this one still works well as a starter.
    NOTE: The "accdb" version is tested and works in Access 2007 through Access 2016, both 32 bit and 64 bit version.
    I recent added code to track and record all changes to data in this version.

    It creates an audit of data changes by user who made the change and the date and time on which the change was made.
    Please report any bugs in this newest version, so I can fix them.
    The change history function is NOT included in the mdb version.
    Like all of my samples and demos, this one is offered "As Is" with no guarantees of fitness for any particular purpose. Use it or modify at your own risk and with your own effort.
    This ZIP file contains both mdb (tested in A2003) and accdb (tested in A2007 through A2016 and A2016 64 bit) versions. Only the accdb version contains the Change History Function.

    GPC Curated Links to Normalization Articles
    I believe it's important that you understand what relational database applications are and how they work. The most important principal is that Relational Databases are NOT just super-charged spreadsheets. While there are many good references on the web to choose from, I've limited the list to these favorites.
