Microsoft has formally introduced a multi-phase plan to deprecate VBScript in Home windows, a transfer that indicators a major shift for builders, significantly these working with Visible Fundamental for Functions (VBA).
The change, first detailed in Could 2024, will regularly section out the legacy scripting language, requiring builders to adapt their tasks to make sure future compatibility.
This choice primarily impacts VBA functions that depend on VBScript for functionalities like executing exterior scripts or using reference libraries, such because the broadly used VBScript.RegExp for dealing with common expressions.
As Home windows evolves, builders are being urged to organize for a future with out VBScript.
The Three-Part Deprecation Timeline
Microsoft has outlined a transparent, three-stage course of for retiring VBScript. The primary section, presently energetic and anticipated to final till at the very least 2026, treats VBScript as a “Characteristic on Demand” (FOD), which means it stays enabled by default, and current VBA tasks will proceed to perform with out interruption.
Within the second section, projected to start round 2027, the VBScript FOD will probably be disabled by default. Whereas directors will nonetheless have the choice to re-enable it, this marks a essential level the place un-updated functions could start to fail.
The ultimate section, with a yet-to-be-determined date, will see VBScript fully faraway from all future Home windows releases, making any remaining dependencies out of date.
The deprecation will have an effect on VBA tasks in two main methods. First, any code that calls and executes exterior .vbs information will not be supported as soon as VBScript is disabled or eliminated.
Second, and extra critically for a lot of, references to the VBScript kind library for normal expressions will break.
This has been a typical methodology for builders to implement sample matching and textual content manipulation inside Workplace functions like Excel, Phrase, and Entry.
With out proactive modifications, these important features will stop to function in newer Home windows environments, probably crippling advanced macros and automatic workflows that depend upon them.
Future-Proofing With Built-in RegExp
To handle this, Microsoft has built-in RegExp lessons instantly into the VBA runtime library, beginning with Microsoft 365 Model 2508 (Construct 19127.20154).
This replace permits builders to make use of common expressions natively with out referencing the exterior vbscript.dll.
The brand new implementation helps each early binding (Dim regEx As RegExp) and late binding (CreateObject(“VBScript.RegExp”)), guaranteeing that up to date Workplace variations can run scripts seamlessly, even on future Home windows variations the place VBScript is absent.
Microsoft strongly recommends that builders improve to the newest Workplace construct, start utilizing the brand new built-in RegExp lessons of their macros, and completely take a look at current tasks to determine and resolve any lingering VBScript dependencies.
