VBA: How to prevent 'Object variable or With block variable not set' scenarios when using Workbook_Open event?
I've hit a wall trying to I'm working with an scenario with the `Workbook_Open` event in my VBA project for Excel 2016. The idea is to execute some initialization code when the workbook opens, but I'm getting an 'Object variable or With block variable not set' behavior when trying to access a specific sheet that I know exists. Here's the code I have: ```vba Private Sub Workbook_Open() Dim ws As Worksheet Set ws = ThisWorkbook.Sheets("DataSheet") ws.Range("A1").Value = "Initialized" End Sub ``` I've verified multiple times that the sheet named "DataSheet" is indeed in the workbook. However, the behavior occurs, and I suspect it's because the `Workbook_Open` event might be firing before Excel has fully initialized the workbook's object model. I've tried adding a delay using `Application.Wait`, but that doesn't seem to help. Is there a better approach to ensure the sheet is fully accessible, or am I missing something else? Also, I've checked that there are no typos in the sheet name, and I confirmed that it is not hidden or protected. Any suggestions or best practices for using the `Workbook_Open` event effectively would be greatly appreciated! For reference, this is a production service. Any feedback is welcome!
