Otto,

It is going to be continuously updating if it takes more than one second to redisplay the entire browse (especially if you are doing this over the internet).

Consider instead, just adding a Refresh button.

... don't know how to do it with three fields? For a single field, you just use a GET with an ON CHANGE clause. For each change you do a seek, then redisplay the browse. When you have more than one GET, then things can get really complicated. They could each work independently, or all three at once. ...

Cool

Not that I'm aware of.

Enrico, James,

Thanks!

So do we need to modify something in FWH regarding this ?

Enrico,

Thanks for finding that.

James, from the MSDN, GetWindowRect() function: In conformance with conventions for the RECT structure, the bottom-right coordinates of the returned rectangle are exclusive. In other words, the pixel at (right, bottom) lies immediately outside the rectangle. So, the +1 has been already taken into ac...

Enrico, OK, I have done some tests and if you add 1 to the width and height, each time you save and restore it, the values grow by one. Try the test code below. Although 101-100 = 1 and the true width is 2 pixels, it seems that Windows (or FW, or (x)Harbour) draws it correctly when you specify the w...

Enrico,

Ok, I see what you're saying, but my example seems to be working. I'll do more tests.

James,

no!

Size of 100, 101 is 2 pixels (100 and 101) not 1 pixel.

EMG

Enrico,

I guess you are confirming my point?

The +1 in not needed, at least in this instance.

James

James,

aCoord := {100,100,101,101}

width = 101 - 100 = 1

or

width = 101 - 100 + 1 = 2

?



EMG

Sorry, I don't understand. The coordinates are aCoord := {100,100,300,500}, so the dimensions are:

width:= 500 - 100 = 400
height:= 300 - 100 = 200

James,

it is just a guess. To properly calculate a dimension we need to use +1.

If +1 is not needed then somewhere there is a wrong code...

Antonio,

Are you saying there is a bug in the Windows class, or in my example, or elsewhere?
