Not enough memory crash when loading VBA userform

Question

Background:

I have a VBA userform with ~1050 checkboxes, and ~100 labels, all populated from the active Sheet. The labels are taken directly from t

I can't speak to why your Excel is crashing, but you could probably cut down some code by loading some values into an Array, then instead of 6 For v = 0 to 28 loops you could have two nested loops, the inner one iterating through your array:

Dim start As Long, z As Long, arr As Variant

start = 1
arr = Array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "1", "2", "3", "4", "5", "6", "7", "8", "9")

For v = 0 To 28
    For z = 0 To UBound(arr)
        If Len(WorksheetFunction.Substitute(.Cells(r, c + 3 + v), arr(z), "")) < Len(.Cells(r, c + 3 + v)) Then Controls("CheckBox" & start + v).Value = True
        start = start + 30
    Next z
    start = 1
Next
