Changes in the workbook saved, it is automatically backed up
do not use the Save As, thisWorkbook.SaveAs "d: \ data \ 1.xlsx"
so when Save finished, it will automatically open the saved file 1.xlsx, the current file will be changed 1.xlsx is
to ensure that all operations are in the original file, can not affect the user's operation
There is secretly saved events:
edit the workbook file: Workbook - beforeSave
thisWorkbook.savecopyas "d: \ data \ 1.xlsx"
When you click save time, would secretly keep a backup file
"d: \ data \ 1.xlsx "changed to" d:. \ data \ " & format (now ()," yyyymmddhhmmss ") &" xlsx "
If you can not remember, to record a macro, copy the code, you can modify the code
The set of all functions worksheet:
application.WorksheetFunction.CountA (sheet2.range ( "a: a")) Table II a number of non-null columns
WorksheetFunction.CountIf(sheet2.range("f:f"), "男")
WorksheetFunction.VLookup(sheet1.range("d9"), sheet2.range("a:b"), 5, 0)
VBA error occurs, continue:
Error avoidance:
ON error Resume the Next
For text: text digital to digital: val (l)
Text-to-digital: L = L *. 1 (multiplied. 1)
IF vba.Information.IsNumeric (L) = False or L <0 the then
IF the IsNumeric (L) = false or l <0 then
dim i as string
The resulting array is divided: Split (the Range ( "a2"), "-") (0)
自定义公式：
function zmj(str as String, str1 as string, i as Integer)
if str = "男" then...
end function
function jqzf(str as String, str1 as string, i as Integer)
jqzf == split(str,str1)(i-1)
end function
sub cjb(str as string)
...
end sub
sub test()
call cjb(sheet1.range("a1"))
