I would like to add a button or a menu pick to Excel asking it to refresh all
cells which referances a user defined function in an Add-in.

For example:

Cells
a1
=ExternalData("source1")

a2
=ExternalData("source2")
....

After button click ExternalData should refresh its data.

Any help would be great!

Thanks

Roland

Press Ctrl + A followed by F9 to refresh all cells with UDF

or, programatically, for an individual cell, say E5,

Range("E5").Activate
Calculate

I have come up with two ways good or bad.

if I put Application.Volatile in the function it does get call each time.

function ExternalData(dataSource)
Application.Volatile
....
end function


The other way
placed a button on the sheet

sub buttonClick()
me.Range("cellChange").value = "change"
end sub

This cause the function to fire also

function ExternalData(dataSource,cellChange)
....
end function
