So here’s a new post on something I’ve been using for years. A simple actionlist that has grown to a tool I use very often. Maybe ‘tool’ sounds complicated, but it really isn’t, I guess thats part of why I like it so much. So what is it? In its essence its a way of working to get your project meetings done efficiently. As a side effect I created a spreadsheet with several tabs for listing actions, issues, risks and the like for a project. Over the years it changed to reflect my way of working, so maybe its better to elaborate on that before explaining the sheet. Continue reading
This is a similar piece of code as the ExcelSettingsStack posted earlier.
It does pretty much the same thing, but has some differences due to Excel settings being read/write and Access settings mostly being write-only. It provides the same two base functions; Push and Pop. The Push function stores the provided settings (or current settings for all optionals left blank) and sets them. Upon Pop, the previous settings on the stack are restored. If settings are write-only, the previous value on the stack is used as the current setting. The current setttings can be retrieved through the Last property.
Often if procedures are called from existing code they change these settings, which makes it hard to track the current settings when a call returns. This code provides a stack to be used for Excel Application based settings, it provides two base functions; Push and Pop. The Push function stores the provided settings (or current settings for all optionals left blank) and sets them. Upon Pop, the previous settings on the stack are restored.
Modulo 11 is a method to calculate checksums or verification digits to numeric data. Its used extensively throughout the world in cases such as bankaccount numbers, creditcard numbers, ISBN numbers and the like. The basic idea is not as much encryption or something similar, but more a protection against human errors. By calculating and verifying the checksum you can quickly detect cases like changing a single digit, switching digits, missing a digit, etc. By verifying a number as early as possible, you can decrease the amount of rubish entering a business process, and hence ease operations.
Here’s some code that I’m pretty proud of, its a nifty piece of code that allows to store any kind of data in a simple textbased container. It uses a custom Base64 encoding to store integers, floats, strings, booleans or blobs in a text block and adds some CRC checks and even some repair capabilities.
In VBA you may occasionally want to store some settings outside of the document. The registry is one way, but I often try to keep it in INI files as automated documents get spread through email easily, but usually do not get ‘uninstalled’ hence the settings will never be cleaned up. I’d rather leave an orphaned file than polute the registry. Other advantages are that its easier to support because a user can email them, or its easier to edit by a user.
Here’s another post of something I created long ago, yet never got to post. Just trying to catch up here 🙂
While looking for a control myself to achieve this, I couldn’t find any. Some VB6 controls we’re available, yet when distributing spreadsheets or databases I just don’t like to create to much dependencies on external controls. Quite often the support required goes through the roof when external dependencies are used.
Often if you create an Excel workbook with some automation features, you want to make sure that users enable macros to be sure the workbook behaves as designed. You can built in as many verification features as you want, but if the macros are disabled, they just won’t work.
If you’ve ever opened a VBA code file with a text editor, you’ve probably noticed the “attribute” statements at the start of the file. Even though you cannot modify these in the VBA editor, they allow you to add some spice to your VBA code. Continue reading
I found events in microsoft outlook to be unreliable. If a modal dialog box is open (eg. MsgBox or InputBox) or a piece of code takes to long to complete, events in the background will be cancelled. This class tries to catch the Add and Change events of a folder but will also check, after handling an item, if additional changes have occured and will then handle those subsequentially.
