Win32API SystemParametersInfo in VB.NET

[Shamil Salakhetdinov]

Hi All,

I did try by myself and I did search on google but I can't find any info on
how to use SystemParametersInfo Win32API in VB.NET

Any useful samples, hints, tips & tricks will be greatly appreciated!

TIA,
Shamil

how to use SystemParametersInfo Win32API in VB.NET

First, I suggest to take a look at 'SystemInformation'. In addition to
that, you can p/invoke 'SystemParametersInfo'
(<URL:http://www.pinvoke.net/default.aspx/user32.SystemParametersInfo>).

Thank you, Herfried!

I did check the URL you posted in your answer.
Looks OK but my task is more complicated I think.
I wanted to use SystemInformation API to get NONCLIENTMETRICS and logical
fonts information like in VB6 sample here:
http://www.activevb.de/tipps/vb6tipps/tipp0211.html

The problem is that I can't make marchaling working OK with NONCLIENTMETRICS
class/structure.
Marchal.SizeOf(...) returns wrong size of this structure - 200 instead of
340 and MarchalStructureToPtr(...) doesn't work well either with
NONCLIENTMETRICS class/structure I think (I can be wrong)

So, I may need more advanced samples/hints..
System.Windows.Forms.SystemInformation misses some info from
NONCLIENTMETRICS structure....

I did find two solutions: the first one doesn't use marchaling, the second
one does use it.
Solutions are simple - they are published here:
