GetCurrentHwProfile
[New - Windows NT]
The GetCurrentHwProfile function retrieves information about the current hardware profile for the
local computer.
BOOL GetCurrentHwProfile(
LPHW_PROFILE_INFO lpHwProfileInfo
| // receives the hardware profile information
| );
|
|
Parameters
lpHwProfileInfo
Pointer to an HW_PROFILE_INFO structure in which the function returns information about the current
hardware profile.
Return Values
If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The GetCurrentHwProfile function retrieves the display name and globally unique identifier (GUID)
string for the hardware profile. The function also retrieves the reported docking
state for portable computers with docking stations.
The system generates a GUID for each hardware profile and stores it as a
string in the registry. You can use GetCurrentHwProfile to retrieve the GUID string to use as a registry subkey under your
application's configuration settings key in HKEY_CURRENT_USER. This enables you to store each user's settings for each hardware profile.
For example, the Colors control panel application could use the subkey to store
each user's color preferences for different hardware profiles, such as profiles
for the docked and undocked states. Applications that use this functionality
can check the current hardware profile when they start up, and update their
settings accordingly.
Windows 95: Applications can also update their settings when a system device message, such
as DBT_CONFIGCHANGED, indicates that the hardware profile has changed.
Example
#include <windows.h>
#include <stdio.h>
#include <tchar.h>
HW_PROFILE_INFO HwProfInfo;
if (!GetCurrentHwProfile(&HwProfInfo)) {
_tprintf(TEXT("GetCurrentHwProfile failed with error %lx\n"),
GetLastError());
return;
}
_tprintf(TEXT("DockInfo = %d\n"), HwProfInfo.dwDockInfo);
_tprintf(TEXT("Profile Guid = %s\n"), HwProfInfo.szHwProfileGuid);
_tprintf(TEXT("Friendly Name = %s\n"), HwProfInfo.szHwProfileName);
} // main

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
