Visual Basic for Applications articles
In part one, Juan talked about the sequence of events fired when loading a form with a number of subforms in Access and how one can reduce the cascading effects of events being re-fired due to operations performed during the load. We will talk about how we can delay loading the subforms. By putting [...]
We use subforms in Access a lot around here. Sometimes, we may have upwards of 5 or 6 subforms per form. Adding that many can be a real drag on performance if you're not careful. This is part one of two posts on the topic. Ben will talk about disabling the loading of subforms on startup in our next [...]
This is a part one of two-part on how you can make your queries much more powerful. In first part, we look at whether we're in or not. Part two can be found here. The IN clause is a great tool to have in your arsenal, it can allow your forms to be editable or filter forms using . What is the IN clau [...]
Whenever the subject of new web apps introduced with 2013 or web databases introduced with 2010, one common lamentation bought up by people is that they both lack VBA. It is certainly an understandable lamentation; almost all serious Access developers have used VBA and it's VBA that makes it possibl [...]
This is part two of two-parts on maximizing code reuse. Part one focused on assigning more than one event handlers to same object's event or sharing an event handler for several objects. We now turn to looking at how we can write design-time automation to help us save time in coding. If you enjoy lo [...]
Sometimes, we have recurring tasks that we would like to simplify and when those tasks involve interactions with the Access object model, we certainly don't want to miss out on the built-in intellisense. Do you have any intellisense? At IT Impact we frequently open forms in our code with a where cla [...]
A while ago, I wrote about securing the ODBC connections which was published on Access team's blog. Also, Juan recently wrote about the alternate method of deleting/recreating linked tables in a four part article. But what about ADO connections? A typical approach for creating an ADO connection may [...]
Author note: This is part 3 of a series on DSN-less tables in Access. You can review part one here. Part 2 here. Part 4 here. In part three of this series I'm going to give you the code to delete all of your linked tables once the app closes. Deleting your links makes your app secure since both the [...]
Author note: This is part 2 of a series on DSN-less tables in Access. You can review part one here. Part three here. Part four here. In last week's post I talked about using a single table in your SQL Server database to easily manage security, in today's post I'm going to take it one step further an [...]
Many of you know that I'm a big fan of Access with SQL Server, and if you're a frequent blog reader you will also know it's not easy to optimize the relationship between them, it takes work but it's very rewarding when they're working great. Some developers however go to the extreme and use unbound [...]
In one of our client's applications, we built an email template that sometimes may attach files to be sent out. Our client wanted a way to preview the attachment before they actually send the email. This created a dilemma - if they can preview and potentially edit the files, we certainly don't want [...]
