give make every entry point routine a Sub and every non-entry point routine a Function. If you're doing your error handling in the way described in this book, then you should be fine.īasically Bovey et al. Ideas, please? It wouldn't be too elegant to let every hook always deal with the Application.EnableEvents = True cleanup - it should only be concerned with it's own, feature-specific error handling. Here, Module is an Object that holds the VBComponent, and hook_WorksheetChange() is an actual Sub defined in a module. My question: Is there a way to invoke a specifically named function inside an unkown module without Application.Run, so my errors bubble up to the dispatcher? I tried this: Call Module.hook_WorksheetChange()īut it didn't compile (I wasn't holding my breath over its success, but I hoped.). This will also leave the application events set to False, which is bad (remember that I'm setting them to False just before I invoke the hook).

Sounds like a good idea, but because I use Application.Run(), the whole error-handling mechanism gets broken in the middle, so the dispatcher won't receive any error that happens inside a hook that is invoked like that. My problem: I'd like to make a general error handler above all hooks, so that if one hook screws something up, I could catch the error inside my top dispatcher and re-enable events. Even better, different people will work on different features inside different hook modules (BIG BONUS).Īs I said, this works, but I must also call Application.EnableEvents = False before these invocations, and Application.EnableEvents = True after the invocations, so I don't end up in infinite invocation loops.

This means I allow any number of modules to act upon, say, Workbook_SheetChange, without polluting the code in ThisWorkbook. Not very original, I know, but if I loop over all the modules and invoke hooks for all Workbook events, it's beginning to smell a little like AOP. Here's what I've done: a dispatcher module, which basically loops over all the modules in my project, and tests whether they start with a specific prefix (a hint that they're hook modules), and when it finds one, it does this: Call Application.Run(Module.Name & ".hook_" & HookName) I've done it, it works nicely, but I have a little shortcoming. The reason of my endeavour is that I've found no other way of properly dividing the work across a team, so with this mechanism I hope to bring a little of Drupal's tried-and-true hook invocation system. These methods help us get a particular cell data or to set a particular cell data, etc.I'm trying to improvise a Drupal-like hook mechanism in VBA (go ahead and criticise, I know it sounds stupid). Step 3 − Let us create generic methods to access the Excel file using the imported JARs. Step 2 − Execute all the percent calculator functions for all the specified parameters. Step 1 − We will parameterize all the inputs required for percent calculator using Excel. Apart from that, add 'WebDriver' related JAR's Parameterizationįor demonstration, we will parameterize the percent calculator test. Step 9 − The Package Explorer is displayed as shown below. Step 8 − The Added JAR is displayed as shown below.

Step 7 − Now add all the 'External JARs' under the 'lib' folder. Step 6 − Now add all the 'External JARs' under the 'ooxml-lib' folder. Step 5 − Now create a new project and add all the 'External JARs' under 'poi-3.10.FINAL' folder. Step 4 − Unzipped contents would be displayed as shown below.

Step 2 − Click on the Mirror Link to download the JAR's.

Step 1 − Navigate to the URL - and download the ZIP format. We will make use of Apache POI - Excel JAR's to achieve the same. While designing a test, parameterizing the tests is inevitable.
