Using Control Panel

Introduction

Sometimes we need to show a control panel applet (control panel page) from our program. That is necessary when users of your program often change some system settings and you want to provide an easy interface for that. This article shows how to open certain control panel applet from your program.

You should be careful because some Pocket PC devices don't support some control panel applets. You can find information about applets support in Creating Shortcuts to Feature Settings article by Steven Perry.

To open a Control Panel Page

You have to run ctlpnl.exe program with "cplmain.cpl,X,Y" argument where X is Id of the control panel applet and Y is an index of a tab page (most applets have several tabs). Here is a sample code that openes a control page with information about alarms.

CString strParam; strParam.Format(_T("cplmain.cpl,%d,%d"), 16, 1); PROCESS_INFORMATION pi; if (!::CreateProcess(_T("\\Windows\\ctlpnl.exe"), strParam, NULL, NULL, FALSE, 0, NULL, NULL, NULL, &pi)) { //Cannot start Control Panel process }

 

STControlPanel

You can also use STControlPanel library that encapsulates working with the control panel. You should create a CSTControlPanel object using control panel applet id and tab page index (the second parameter is optional).

Here is a sample code that openes a control page with information about alarms.

CSTControlPanel cp(ST_CPAPPLET_CLOCK, ST_CPAPPLET_CLOCK_ALARMS); cp.Open();

 

Control Panel Applets

This section enumerates only some control panel applets. Some devices contain more applets then the others, and not all enumerated applets are supported by all devices.
