how to get the sum?????

Welcome to the forums... :wave:

What are you referring with the word 'column' ? An array? ListView column ? FlexGrid column ?

flexgrid

Something like this might work:

VB Code:

Dim index As Integer
Dim mySum As Double
Dim columnToSum as integer
 
mySum = 0
columnToSum = 1
 
For index = 1 To (MSFlexGrid1.Rows - 1)
    mySum = mySum + Val(MSFlexGrid1.TextMatrix(index, columnToSum))
Next index
 
MsgBox mySum

Make the index variable a long if you have more than 32767 rows in your grid.
I started at index = 1 as I assumed you have a header row, if you don't and just have data without a header, change "index = 1 to" to "index = 0 to".

I'm not sure if there is a way to run a sub-sql-query directly on the underlying RecordSet but if not then the above hopefully works for you.

You might want to add some validation in case of NULL values.
