Hi Everybody,

I have an array full of numbers that I plot on the screen.

For easy reference, lets say my array holds 100,000 numbers and I display 1000 at a time. My user can page forward and back through all this data.

I would like to show some kind of "you are here" type bar so they have an idea of where in the data they are.

Can anyone please give me some ideas as to how I would do this?

Thanks,

Jeff Barnes

Hello Jeff,

I am working on a new datepicker. I would like to select the duration of an appointment with the mouse. The position of the mouse shows a tooltip with the date of the mouseposition.
As I use an array to hold the days of the year I thought maybe this could be of use
for you. Depending on the length of the numbers I see no problem to show 1000 on a screen.
As I use oWnd:say to show the “cells” I don’t have problems with handles and memory.
If this could be of help I send you the sources.
Regrads,
Otto

The idea to such a type of datepicker is from Timm ( Easyreport).
He resolved the task with a browser I try to do the same with
an array.

Thanks Otto.

But I think what I need is something like a scrollbar that you see in a browse but horizontal.

Do you know if there is a scrollbar control?

Thanks,

Jeff, could you post some of the numbers to see how you would like to plot them.
Regards,

Jeff, if you define the Window with

DEFINE WINDOW oWndPlan TITLE "Kalender" ;
HSCROLL ;
FROM 5, 5 TO 24, 98
you have the scrollbar.

Then you can use these methods:
oWindPlan:oHScroll():SetRange(1,oWindPlan:nHorzRes())
oWindPlan:oHScroll():SetPos(oWindPlan:nHorzRes()/2)

oWindPlan:oHScroll():SetPos(nPos:=nPos+7));
here you can use 100 or 1000 ...

Regards,
Otto

Otto,

Here is a screen shot. I already have the data plotted ... I just need a way to let the user know where they are in the record (array).

Thanks Otto.

Using your suggestions I am almost there.

Is it possible to have the scrollbar somewhere else on the screen (other than at the bottom)?

Thanks,
