In the Delphi program, call the Control Panel Settings the function of the King Army application, sometimes there is a special requirement for the system environment. For example, in the Delphi database application, you may need to set up BDE (BORLAND DATABASE Engine) or ODBC Data Source Name (DSN: Data Source Name); network configuration settings, modem properties settings or user dialings may be required in the network application Connected account and password settings are saved in the system; in the CTI (Computer-Telephony Integration) application, you may need to perform the settings for telephone dialing properties; in the game program, you may need to set the multimedia or game controller; etc. . At this time, you need to change the environmental settings of the Windows system to accommodate the requirements of the normal operation of the application. When the application cannot be able to set up an environment setting, it may be necessary to participate in and assist completion settings.
Most of WIN9X / NT's system settings are performed in the control panel. We can ask the user to open the control panel to find the corresponding project for settings. At this time, the user is required to be quite familiar with the control panel; or the user can automatically open the control panel to the user and select the corresponding item. At this time, the user is only performed. Set. The latter method is undoubtedly more friendly, which can improve the user's work efficiency.
Most of the control panels, all of which correspond to a CPL file in the system directory of Windows, such as the file corresponding to the "Internet" property, the file corresponding to the INETCPL.CPL, "Multimedia" attribute, is mmsys.cpl, etc.. By calling these files, you can open the appropriate property settings window, even skip to the "Connection" property page of the corresponding property page, such as the Internet property, effectively reducing the steps of software users.
The call format of the CPL file is "rundll32.exe shell32.dll, control_rundll cplfile.cpl, item" (see the default value of HKEY_CLASSES_ROOT / CPLFILE / shell / CPLOPEN / COMMAN) in the registry), where cplfile.cpl is a CPL file, ItemNo is the project number. In the Delphi program, you can use the WINEXEC or CREATEPROCESS function to implement the CPL file call to implement the call to the control panel. If the account number and password setting for dial-up connection To call the "Internet" property "Connection" property page, you can use the statement "WINEXEC ('rundll32.exe shell32.dll, control_rundll inetcpl.cpl, 3', sw_shownormal);" Solve the interpretation of the 2000 issue to call the "Regional Settings" property page for the "Regional Settings" property page, you can use statements: "Rundll32.exe shell32.dll, control_rundll intl.cpl, 4 ', 4', Sw_Shownormal); ". The list of statements corresponding to the corresponding statements corresponding to each item setting call:
