C # Call Control Panel options

Control C # is a new development language developed by Microsoft, and it is an emerging development tool based on the Microsoft. NET Framework platform.

Because it was introduced by Microsoft, its compatibility and interoperability with all of Microsoft's products was beyond the programming language developed by other companies. The relationship between the Windows operating system developed by Microsoft and C # is also very close. This enables C # seamless operation of Windows.

Below, let's take a look at the connection between the "C # Action on the options in Windows Control Panel."

In the Windows operating system, the Control Panel file is typically a ". cpl" suffix, and the following table lists the common options and their file names for Windows Control Panel:

-------------------------------------------------------------------------------------------------

Option file name

--------------------------------------------------------------------------------------------------

Internet Options: Inetcpl.cpl

ODBC Data source management: Odbccp32.cpl

Phone and Modem Options: telephon.cpl

Power Options: Powercfg.cpl

Accessibility Options: Access.cpl

Regional and Language Options: intl.cpl

Date and time: timedate.cpl

Sound and Audio Devices: mmsys.cpl

Mouse: main.cpl

Add or Remove Programs: appwiz.cpl

Add Hardware: hdwwiz.cpl

Network connection: Ncpa.cpl

System: Sysdm.cpl

Show: Desk.cpl

User account: Nusrmgr.cpl

Game controller: Joy.cpl

Voice: Sapi.cpl

----------------------------------------------------------------------------------------------------

Font: Fonts

----------------------------------------------------------------------------------------------------

These are the options in the common Control Panel.

Operation:

We can open an operation in C # in the following ways:

A using system.diagnostics;//is called when the namespace is invoked.

In event handling we can use the following methods:

Try

{

Process.Start ("[with full name of the filename above]");

}

catch (Win32Exception Win32ex)

{

MessageBox.Show ("Cause of Error:" +win32ex.) Message, "Error", Messageboxbuttons.ok,messageboxicon.error);

}

Example:

Let's take the Internet option as an example:

Let's revise the above code to read:

Using System.Diagnostics;

ProcessStartInfo info=new ProcessStartInfo ();

Try

{

Info.filename= "Inetcpl.cpl";

Process.Start (Info);

}

catch (Win32Exception Win32ex)

{

MessageBox.Show ("Cause of Error:" +win32ex.) Message, "Error", Messageboxbuttons.ok,messageboxicon.error);

}

The following effects occur after the program is run:



If we do not enter the full file name in the program, an error will occur and the following message appears:
