AutoScrollBar width...

[Thorbjørn Jørgensen]

Hi
I know that I have posted this question before, but sine no one did reply I
might not have explanind my self well enough, so I will try once more...
I have created a UserControl which inherits from Forms.UserControl. On the
usercontrol I am painting some lines and stringsswith GDI. I need to place a
string at the right edge, this is done by calculating the placement of the
string box from the width of the usercontrol. But since I in some cases need
to scroll to show all of the usercontorl I have set AutoSroll=trus, and set
the AutoScrollSize. But since I calculate the placement of the string from
the width of usercontrol I need to know the width of the scrollbar when it
is present. Hos do i find the properties of the AutoScroll bar, or solve
this problem in some other way?

Regards
Thorbjørn

Thorbjørn,

Sorry I didn't respond the other day, I wasn't sure of the answer and
assumed someone more knowledgeable than me would respond!

Anyway, I have just done a little research and it looks like what you need
to do is check the difference between the Bounds property and the
DisplayRectangle property.

Bounds shows the overall position & size of the control relative to the form.
DisplayRectangle shows the position & size of the content area of the
control (which I am pretty sure excludes the scrollbars) relative to the top
left of the Bounds rectangle.

Good luck,
Chris.

You are not obligated to answer my questions. The only reason that I
reposted, was that I thought that I had explained my self badly...

Bounds shows the overall position & size of the control relative to the

top

Great... It works... That did the job, thank you very much...

In addition to the solution Chris gave you, you can discover the width or
height of scrollbars in the SystemInformation class.
