Vb6 current recordset does not support updating
LAA doubles available virtual memory from 2GB to 4GB when using 64-bit Windows, and increases available virtual memory from 2GB to 3GB under 32-bit Windows. And with Tables sometimes it seems best to work with a Range that represents the table rather than directly with List Rows: the syntax is not always obvious to me.
Because Excel internally uses a sparse matrix scheme for the cells in each worksheet (instead of holding a gigantic 16384 by 1048576 array) it has to store information for each cell that has been used. Of the Java Script array methods bench-marked, Reduce and direct processing of the proxy object were slower than direct looping on an array.
So formatted cells are considered used, as well as cells containing values and formulas. Row When using End(xl Up) you want start outside the range in an empty cell, so I used Offset to get to the first row below the range. Using End(xl Down) is simpler for a Range: the code start at the first row in the range and ends at the first of the last visible row in the range that contains data and the last row before an empty cell. ' ' last row in Table using End(xl UP) - Note End(xl Up ) behaves differently for tables - includes hidden rows ' j Last In Table2 = o Sht. Using a worksheet function such as COUNTIFS is considerably faster than looping an array as long as you can avoid transferring the data to VBA or Java Script.
TEXTJOIN and CONCAT let you easily combine text strings from ranges of cells. ' ' last row containing data (using Find in formulas) ' j Last Range Data = o Sht. Find(What:="*", Look In:=xl Formulas, Search Order:=xl By Rows, Search Direction:=xl Previous). This version of Invoke Run loops directly on the proxy object values rather than on an array derived from the proxy object.
These functions can replace the slow VBA UDFs typically used in previous versions. Row So using End(xl Up) starting from the first row after the end of the table returns Row 25 even though that row is hidden. Using Find on Formulas includes hidden rows, whereas using Find on Values excludes hidden rows. Row ' ' last visible row containing data (using Find in values) ' j Last Visible Range Data = o Sht. Find(What:="*", Look In:=xl Values, Search Order:=xl By Rows, Search Direction:=xl Previous). Find(What:="*", Look In:=xl Formulas, Search Order:=xl By Rows, Search Direction:=xl Previous). Find(What:="*", Look In:=xl Values, Search Order:=xl By Rows, Search Direction:=xl Previous). This version of Invoke Run uses Java Script’s REDUCE array method, where you supply an aggregating function to be applied to each row of the array.
Cells remain flagged as used even when all formatting, values and formulas are removed. Row ' ' last visible cell in Named Range using End(xl Down) ' j Last Visible Range2 = o Sht. As an Excel Office Developer many of the Excel based applications I develop depend on reading data from Excel worksheet ranges, processing it and then writing the processed data back to a worksheet.

Row ' ' last visible table row using End(xl Down) ' j Last Visible Table = o Sht. But End(xl Down) works the same way with a table as with a Range, and so returns row row 20 which is indeed the last visible row in the table. Row ' ' last row containing data (using Find in formulas) ' j Last Table Data = o Sht. Row ' ' last visible row containing data (using Find in values) ' j Last Visible Table Data = o Sht. Row Sometimes its simpler to just count the number of rows, add the starting row number and subtract 1. Sub Find XY3() Dim v Arr As Variant Dim j As Long Dim n As Long Dim d Time As Double Dim d Time2 As Double d Time2 = Micro Timer v Arr = Range("a1: B100000").Using VBA to get the last row in Excel can be a surprisingly complex task. ‘ ‘ last cell in Named Range ‘ j Last In Range = o Sht. Value2 d Time = Micro Timer For j = LBound(v Arr) To UBound(v Arr) If v Arr(j, 1) = "X" Then If v Arr(j, 2) = "Y" Then n = n 1 End If End If Next j Debug.
This post discusses some of the features that have been introduced in Excel 2016 that you can use to improve performance with large or complex workbooks.Performance was highly dependent on the count of all rows between the top visible row and the bottom visible row. Of course then when I change rng3 I am also changing rng1 but that does not matter (although probably bad practice) because I am not returning rng1 back to the worksheet.An improvement made to the internal calculation of vertical user interface positions in build 16.0.8431.2058 has made these operations much faster. (rng1 never appears on the left of the = assignment) In a previous post I compared several different ways of processing data with VBA.Update Star includes support for many languages such as English, German, French, Italian, Hungarian, Russian and many more.You can choose your language settings from within the program.LAA has now been enabled for 32-bit versions of Excel 2013 and Excel 2016, and will minimize out of memory error messages. Row – 1 I was really surprised to find that End(xl UP) worked differently for Tables than for Ranges.
