Source : Load Unload Device Driver

很對不起,這個code是base on http://www.ucancode.net/Visual_C_Codes/Loading-DLLs-LoadLibrary-GetProcAddress-FreeLibrary-VC-Example.htm
的 load dll function 寫的,竟然沒有提到,真是抱歉。

我猜原 po 應該是在 Bruce Eitman 的 WINCE Blog:

Windows CE: Loading a Driver with ActivateDeviceEx



這個code是以 load unload driver : SST
cpp

#include "stdafx.h"

#include "resource.h"

#define SST_REG_KEY (TEXT("Drivers\\Builtin\\SST"))

typedef struct {
TCHAR *ValueName;
DWORD Type;
DWORD DwordValue;
TCHAR *StringValue;
} RegEntry;

RegEntry RegEntries[]={

{TEXT("Prefix"),REG_SZ, 0,TEXT("SST")},
{TEXT("Order"), REG_DWORD,4,NULL},
{TEXT("Index"), REG_DWORD,1,NULL},
{NULL,NULL,NULL,NULL}
};

void AddDriverSSTToRegistry()
{
HKEY hTargetKey;
DWORD dwDisposition;
DWORD RetVal;
DWORD Index=0;
BYTE *Value;
DWORD uSize;

SST_REG_KEY,
0,
NULL,

KEY_ALL_ACCESS,

&hTargetKey,

);
if(RetVal == ERROR_SUCCESS)
{
while(RegEntries[Index].ValueName!=NULL)
{
if(RegEntries[Index].Type == REG_DWORD)
{
RegSetValueEx(hTargetKey,
RegEntries[Index].ValueName,
0,
REG_DWORD,
(const BYTE*)&RegEntries[Index].DwordValue,
sizeof(DWORD));
}
else
{
Value = (BYTE *)RegEntries[Index].StringValue;
uSize = (wcslen(RegEntries[Index].StringValue)+1)*sizeof(TCHAR);

RegSetValueEx(hTargetKey,
RegEntries[Index].ValueName,
0,
REG_SZ,
(const BYTE*)RegEntries[Index].StringValue,
(wcslen(RegEntries[Index].StringValue)+1) * sizeof(TCHAR));

}
Index++;
}
}
}

HANDLE hDriverSST=INVALID_HANDLE_VALUE;

BOOL LoadDriverSST(void)
{
BOOL RetVal = NULL;

if(hDriverSST == INVALID_HANDLE_VALUE)
{
hDriverSST = ActivateDeviceEx( SST_REG_KEY,
NULL,
0,
NULL);
if(hDriverSST != INVALID_HANDLE_VALUE && hDriverSST != 0)
RetVal = TRUE;
else
{
RETAILMSG(1,(TEXT("Fail to load Driver SST\n")));
}
}
return RetVal;
}

void UnloadDriverSST(void)
{
if(hDriverSST!= INVALID_HANDLE_VALUE)
{
DeactivateDevice(hDriverSST);
hDriverSST=INVALID_HANDLE_VALUE;
}
}

printf("UNLOAD");
return TRUE;
case IDC_RESISTRY:

return TRUE;
}
break;
default:
return FALSE;
}
}

int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,

{

Could at least give me credit if you are going to use one of my functions in your blog?

Yes, Yes, sorry, This post is a sequal of my previous post - http://realchecko.blogspot.com/2009/09/getprocaddresses-one-time-dll.html ,
So I forget to give the link in this post, I've modified this post.

Sorry for my mistake.

Beside that, I've write http://realchecko.blogspot.com/2009/10/shame-on-me.html on my blog to apology to you.

Checko:

I too am sorry. I did not mean to sound harsh. I should have written "please" with that. I am very pleased by what you have done with my code.

You have a very nice blog - I only wish that I could read Chinese. I must rely on a friend to assist me.

Please use my code in the future in this way.

Thank you very much.

You are a kind person, I got lots of benefits from your codes and blogs.

And thank you for forgiving my ignorance and my poor english.
