得到显示器分辨率

本文相关代码如下：
dim x as short = system.windows.forms.screen.primaryscreen.bounds.width
dim y as short = system.windows.forms.screen.primaryscreen.bounds.height
msgbox("您的显示器分辨率是：" & x & " x " & y)

得到特殊文件夹的路径

本文相关代码如下：
'"desktop"桌面文件夹路径
msgbox(environment.getfolderpath(environment.specialfolder.desktopdirectory))
'"favorites"收藏夹路径
msgbox(environment.getfolderpath(environment.specialfolder.favorites))
'"application data"路径
msgbox(environment.getfolderpath(environment.specialfolder.applicationdata))
'通用写法
'dim spec as string = environment.getfolderpath(environment.specialfolder.xxxxxxx)
'xxxxxxx是特殊文件夹的名字

得到操作系统版本信息

本文相关代码如下：
msgbox(environment.osversion.tostring)

得到当前登录的用户名

本文相关代码如下：
msgbox(environment.username)

得到当前应用程序的路径

本文相关代码如下：
msgbox(environment.currentdirectory)

打开和关闭cd-rom

本文相关代码如下：
'先新建模块
module mciapimodule
declare function mcisendstring lib "winmm.dll" alias "mcisendstringa" _
(byval lpstrcommand as string, byval lpstrreturnstring as string, _
byval ureturnlength as integer, byval hwndcallback as integer) as integer
end module
'打开cd-rom
dim lret as long
lret = mcisendstring("set cdaudio door open", 0&, 0, 0)
'关闭cd-rom
dim lret as long
lret = mcisendstring("set cdaudio door closed", 0&, 0, 0)
'更多请参见
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/mmcmdstr_8eyc.asp

得到计算机ip和计算机全名

本文相关代码如下：
dim myip as system.net.iphostentry = system.net.dns.gethostbyname(system.net.dns.gethostname)
msgbox("您的ip地址：" & (myip.addresslist.getvalue(0).tostring))
msgbox("您的计算机全名：" & (myip.hostname.tostring))

使用win32_operatingsystem (wmi class)得到计算机信息

本文相关代码如下：
'添加listbox在form1_load事件里，并引用system.managment
dim opsearch as new managementobjectsearcher("select * from win32_operatingsystem")
dim opinfo as managementobject
for each opinfo in opsearch.get()
listbox1.items.add("name: " & opinfo("name").tostring())
listbox1.items.add("version: " & opinfo("version").tostring())
listbox1.items.add("manufacturer: " & opinfo("manufacturer").tostring())
listbox1.items.add("computer name: " & opinfo("csname").tostring())
listbox1.items.add("windows directory: " & opinfo("windowsdirectory").tostring())
next

列出计算机安装的全部字体，并添加到listbox

本文相关代码如下：
'新建form并添加listbox和button
private sub button1_click(byval sender as system.object, byval e as system.eventargs) handles button1.click
dim fntcollection as installedfontcollection = new installedfontcollection()
dim fntfamily() as fontfamily
fntfamily = fntcollection.families
listbox1.items.clear()
dim i as integer = 0
for i = 0 to fntfamily.length - 1
listbox1.items.add(fntfamily(i).name)
next
end sub

使用win32_processor列出处理器的信息

   本文相关代码如下：
imports system.management
public class form1
inherits system.windows.forms.form
#region " windows 窗体设计器生成的代码 "
public sub new()
mybase.new()
'该调用是 windows 窗体设计器所必需的。
initializecomponent()
'在 initializecomponent() 调用之后添加任何初始化
end sub
'窗体重写 dispose 以清理组件列表。
protected overloads overrides sub dispose(byval disposing as boolean)
if disposing then
    if not (components is nothing) then
      components.dispose()
    end if
end if
mybase.dispose(disposing)
end sub
'windows 窗体设计器所必需的
private components as system.componentmodel.icontainer
'注意: 以下过程是 windows 窗体设计器所必需的
'可以使用 windows 窗体设计器修改此过程。
'不要使用代码编辑器修改它。
