MSCHART

[selimsl]

Hi!

I have a problem with mschart.I didn't know whether there is a solution about this problem.

For i = 1 To 30
        MSChart1.Column = 1
        MSChart1.Row = i
        MSChart1.Data = fifo(i)
Next i

Yes,it works,but when new values are transfered to data property of mschart,mschart control flashs.
Can we prevent this?

Only way I know is to use an API call to lock the hWnd of the chart until it's done populating data.

Declare Function LockWindowUpdate Lib "user32" Alias "LockWindowUpdate" (ByVal hwndLock As Long) As Long

r = LockwindowUpdate(MSChart.hWnd)
<code to fill chart>
r = LockWindowUpdate(0)

Thanks for your reply

Declare Function LockWindowUpdate Lib "user32" (ByVal hwndLock As Long) As Long

I write this code,but when I compile my project
a compile error appears
Where should I write this code

You normally put them in a separate code module (Project|Add Module) which is saved as a .bas file

Whether it's in a module or in the form itself, it goes in the declaration area, same place you put your constants, globals, etc.
Sorry, didn't make that clear in my little code example.

Unfortunately ,mschart control still flashs .
