Multi Send_Message

Michael

Hola all,

Years ago, I read something about a technique to pass multiple Send_Message updates at once, similar to how we send a Set_Property call to set multiple properties. Has anyone done anything with this before?

I have a client who is trying to colorize an edit table, and is executing a Send_Message for nearly every cell in the table. It is Very slow. Looking for an alternative.

Thanks!

I can't say that I am aware of that technique. Have you tried setting the REDRAW property to 0 before the Send_Message calls to see if that reduces the performance lag?

I tried it.. I think it helped a bit, but it's still pretty slow for what we're trying to do.

I remember being able to simulate Send_Message calls with Send_Property, thus allowing multiple Messages to be sent with one call. Will keep digging.

Thanks!

You could "lazily" colour the rows. So catch the scroll event ,and fill in, say, 15 (or how ever many rows are visible) at a time.

Example code for the SRP grid, but you could do the same thing for the OI grid

lazy_load_images: // If the 2 are the same, then the user has stopped scrolling, so we load the images. old_start_row = get_Property(grd_orders$, "OLE.ScrollPos")<2> yield() new_start_row = get_Property(grd_orders$, "OLE.ScrollPos")<2> if old_start_row = new_start_row then nrows = get_Property(grd_orders$, "OLE.Dimension")<2> end_row = min(new_start_row + lazy_load_row_count$,nrows) for i = new_start_row to end_row skn = get_Property(grd_orders$, "OLE.CellText[":sku_col$:"; ":i:"]")[1,6] if get_Property(grd_orders$, "OLE.CellImage[":image_col$:"; ":i:"]") = "0" then Set_Property(grd_orders$, "OLE.CellImage[":image_col$:"; ":i:"]", Itv_Get_Product_Images(skn,"a4")<1>) end Next i end return
