to do some line drawing , so it's very usefull to me ....

Thanks once again,

Hi Esgici,

I have started using your idea but when drawing many lines and erasing them, I found that everytime all the lines are drawn and then erased. Can't we avoid that?

I want a few play with lines (ah, these gold days of DOS ) and me too, I'm wondering answer of this question

My opinion is: this is no erasing but drawing issue, because erasing by this way actually is drawing.

Maybe author of DRAW commands will explain this situation.

Hi Rathi

If version you are using include line :
could you try without it ?

I will check and tell you.

I have a dirty way of erasing the things.

All the draw commands are stored in _HMG_SYSDATA [ 102 ] ( i being the form index as I have mentioned in the first post in this thread).

They are in the order of our commands. So, if I want to erase the draw command that I have drawn first,

I use,

i := getformindex( cFormName )
adel( _HMG_SYSDATA [ 102 ] [ i ], 1 )
asize( _HMG_SYSDATA [ 102 ] [ i ], len( _HMG_SYSDATA [ 102 ] [ i ] ) - 1 )

that's all. Next time the window is painted, the first draw command is not drawn.

Sorry, I can't achieve this method; it work (no causing any problem, error etc), but I can't see the result ( erasing drawn object )

Could you give an example please ?

This point also is obscure for me

I don't know what is "time the window (re) painted"

If this is an "automatic" event made by system, when or under which conditions it occurs

Thanks in advance

Best regards

Hi Esgici,

I will post an example tomorrow.

Window will be automatically repainted whenever it is moved, restored, minimized or movement of mouse over.
