The device manager uses the SetupDixxx APIs to enumerate all classes of devices installed on the system.

CComboBox: button access, list problem

Hi Jonathan,

i tried to use your logic in my application. I have a VC6.0 Win32 console based applicaion, in which i need to enumerate the serial ports. But the CLSIDFromString(wBuf, &Guid) function always fills Guid with zeroes. Do you have any idea what could be the problem.

NB:- guiddef.h header file is not there in my installation, i commented this header inclusion and the code compiles.
Also, your console based demo application works fine in my PC, and list out all ports perfectly.

The API is for Windows CE and Windows Mobile.
You cannot use it for Win32 or x64.

Dear Mr/Ms

Now I have one problem. Pls help me.

I create one process(Temp.exe) and set affinity is CPU 0, in this process, can I create other thread with affinity is CPU 1?

(I already using SetThreadAffinityMask but error raised ERROR_INVALID_PARAMETER)

(OS :WinXP, Core 2 Duo CPUs)

This is my code:
pls help me.

//Create Process with CPU 2 (all thread of this process run in CPU 2)
BOOL result = CreateProcess(NULL,_T("C:\\CPU.exe"),NULL,NULL,FALSE,NORMAL_PRIORITY_CLASS,NULL,NULL,&si,&pi);
SetProcessAffinityMask (pi.hProcess,2L);

in CPU.exe when press button [Check]

HANDLE hThread;
DWORD dum;
hThread = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)threadFunction,NULL,0,&dum);
// but i want this thread run in CPU1 not CPU2
DWORD dWord = SetThreadAffinityMask (hThread,1L); // threadFunction run in CPU 1

// dWord = 0 : raise error, canot set affinity for this thread
Pls help me more information about it.

Thread affinity can only be a subset of the process affinity.
You would probably be able do do this if you set the process affinity to 3.
