Hi,
Consider a custom control, say, MyControl that's being derived from
Control.
1. How am I supposed to set the initial size of MyControl? Am I
supposed to override the DefaultSize property?
2. If so, the VisibleClipBoun ds of the control is not actually what
I've asked in the DefaultSize property, if the BorderStyle of
MyControl is set to FixedSingle or Fixed3D. i.e., if the DefaultSize
is set to "300, 100"; the actual size of the VisibleClipBoun ds in the
OnPaint method will be "296,96" which is obviously 4 pixels lower than
expected.
Any help would be highly appreciated,
Thanks.

Usually, the initial size of your control would be set in the Designer
when you drag it onto another form. But yes, if you want your control to
inherently have some specific default size, overriding DefaultSize is the
way to do that.

I've asked in the DefaultSize property, if the BorderStyle of

I haven't done much with custom bordered controls, but it seems pretty
clear to me that when the border is drawn within the boundary of the
control (as opposed to a window/form where the border is draw in the
"non-client" area), that the border will occupy part of the client area.
If you want your client area to be a full 300x100, you need to set the
size of the control a little larger to account for the border.

I have a program that prints 2 different reports and I have 2 different
printers (hp 9000, hp9050). The first report prints perfectly on both
printers. The second only prints pefectly on the 9000. On the 9050, I only
get a small square's worth in the upper left corner.
I've narrowed the problem down to the VisibleClipBounds(VCB) property of the
Graphic object I'm using to do the drawing. For some reason, on the second
report the VCB...

Has anyone else experienced this? A3 paper size seems to exacerbate the

I can't believe it because the same code is executed with the same exact

0 (l:0, t:0, r:0, b:0) then it prints fine (ok, not quite because 0,0 is
inside the none printable area but I corrected for that by checking...

Hi,
Ok I am doing a print app, what I am trying to do is get the EXACT
boundaries of the page, I want to print to the top left, 0,0, which is fine,
but bottom right is a problem.
When I use ".VisibleClipBounds.Width" I get the correct with the first time,
for the default printer, that is set to A4.
If I select another printer from the list, it gets a bit hairy.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
