Excel VBA代码运行时错误求助：Run Time Error 1004对象错误

Hey there, let's work through why that lC4 = Cells(155, Columns.Count).End(xlToLeft).Column line is throwing a 1004 error. Here are the most common issues and straightforward fixes:

• You're not targeting the correct worksheet
  The Cells and Columns objects automatically use whichever sheet is active when your code runs. If the sheet with row 155 isn't the active one, this can trigger the error. Fix it by explicitly naming your worksheet to avoid ambiguity:

  Dim targetSheet As Worksheet
  Set targetSheet = ThisWorkbook.Sheets("YourSheetName") ' Replace with your actual sheet name
  lC4 = targetSheet.Cells(155, targetSheet.Columns.Count).End(xlToLeft).Column
  

• The worksheet is protected
  If the sheet holding row 155 is protected (even without a password), your code can't access cell properties. Temporarily unprotect the sheet before running this line, then re-protect it if needed:

  targetSheet.Unprotect ' Add your password in quotes if required: targetSheet.Unprotect "YourPassword"
  lC4 = targetSheet.Cells(155, targetSheet.Columns.Count).End(xlToLeft).Column
  targetSheet.Protect ' Re-apply protection with your original settings if needed
  

• Row 155 is completely empty
  If every cell in row 155 is blank, End(xlToLeft) from the last column will land on A155, but in some edge cases (like odd sheet formatting), this can still trigger an error. Add a check to handle empty rows gracefully:

  If WorksheetFunction.CountA(targetSheet.Rows(155)) = 0 Then
      lC4 = 0 ' Or set a default value that fits your code's logic
  Else
      lC4 = targetSheet.Cells(155, targetSheet.Columns.Count).End(xlToLeft).Column
  End If
  

• Merged cells are disrupting the range
  Merged cells in row 155 can break the End(xlToLeft) behavior. If possible, unmerge cells in that row—this is usually the cleanest fix. If you can't unmerge, you'll need to adjust your code to account for merged ranges (though that gets more complex).
