VC点滴1

过完年了,上了3天的班,感觉还是上班比较充实些,放假回家都不知道干什么了. 这段时间一直沉浸于vc中,感觉到vc真的很麻烦,写个UI太费劲了.不过目前的这个DCOM终于大部分的功能都完成了. 整理下其中使用的一些小的部分,记录以后可能也会用到.
1.获取登陆OS的用户名和域名.
因为这次开发用户都是是用AD进行管理的,所以要获取登陆OS的用户名,然后到DB中捞资料然后登陆分机.
获取方法如下:

#define MAX_SID_SIZE 1024

#define MAX_NAME_STRING 1024

//Get OSUser Name

void XXXXXX()

{

TCHAR errorMessage[1024];

TCHAR userName[MAX_NAME_STRING], domainName[MAX_NAME_STRING];

TCHAR subKeyName[MAX_PATH];

DWORD subKeyNameSize, index;

DWORD userNameSize, domainNameSize;

FILETIME lastWriteTime;

HKEY usersKey;

PSID sid;

SID_NAME_USE sidType;

SID_IDENTIFIER_AUTHORITY authority;

BYTE subAuthorityCount;

DWORD authorityVal, revision;

DWORD subAuthorityVal[8] = { 0, 0, 0, 0, 0, 0, 0, 0 };

// Use RegConnectRegistry so that we work with remote computers

if( RegOpenKey( HKEY_USERS, NULL, &usersKey ) != ERROR_SUCCESS ) {

wprintf( errorMessage, L"Error opening HKEY_USERS" );

GetError();

// PrintWin32Error( errorMessage, GetLastError() );

// return FALSE;

}

// Enumerate keys under HKEY_USERS

index = 0;

subKeyNameSize = sizeof( subKeyName );

while( RegEnumKeyEx( usersKey, index, subKeyName, &subKeyNameSize,

NULL, NULL, NULL, &lastWriteTime ) == ERROR_SUCCESS ) {

// Ignore the default subkey and win2K user class subkeys

if( wcsicmp( subKeyName, L".default" ) &&

!wcsstr( subKeyName, L"Classes")) {

// Convert the textual SID into a binary SID

subAuthorityCount= swscanf( subKeyName, L"S-%d-%x-%lu-%lu-%lu-%lu-%lu-%lu-%lu-%lu",

&revision, &authorityVal,

&subAuthorityVal[0],

&subAuthorityVal[1],

&subAuthorityVal[2],

&subAuthorityVal[3],

&subAuthorityVal[4],

&subAuthorityVal[5],

&subAuthorityVal[6],

&subAuthorityVal[7] );

if( subAuthorityCount >= 3 ) {

subAuthorityCount -= 2;

// Note: we can only deal with authority values

// of 4 bytes in length

authority.Value[5] = *(PBYTE) &authorityVal;

authority.Value[4] = *((PBYTE) &authorityVal+1);

authority.Value[3] = *((PBYTE) &authorityVal+2);

authority.Value[2] = *((PBYTE) &authorityVal+3);

authority.Value[1] = 0;

authority.Value[0] = 0;

// Initialize variables for subsequent operations

sid = NULL;

userNameSize = MAX_NAME_STRING;

domainNameSize = MAX_NAME_STRING;

if( AllocateAndInitializeSid( &authority,

subAuthorityCount,

subAuthorityVal[0],

subAuthorityVal[1],

subAuthorityVal[2],

subAuthorityVal[3],

subAuthorityVal[4],

subAuthorityVal[5],

subAuthorityVal[6],

subAuthorityVal[7],

&sid )) {

// We can finally lookup the account name

if( LookupAccountSid( NULL,

sid,

userName,

&userNameSize,

domainName,

&domainNameSize,

&sidType )) {

// We've successfully looked up the user name

if(wcsicmp( domainName, L"NT AUTHORITY"))

{

m_User = userName;

m_Domain = domainName;

UpdateData(FALSE);

wprintf( L"%s\\%s\n", domainName, userName );

}

if( sid ) FreeSid( sid );

}

subKeyNameSize = sizeof( subKeyName );

index++;

}

RegCloseKey( usersKey );

}

2.改变窗口背景色.

HBRUSH CDialFrm::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

switch (nCtlColor) {
  case CTLCOLOR_STATIC:
  case CTLCOLOR_DLG:
  {
   pDC->SetBkMode(TRANSPARENT);
   HBRUSH b = CreateSolidBrush(RGB(0,0,0));
   return (HBRUSH) b;
  }
}
return hbr;
}

目前还差一个，就是跑马灯的实现，现在写了一个跑马灯的类，但是只能支持左到右的跑，按规格上看，也要支持上下才行。如果有人知道这样的类，告诉俺下，谢谢咯。
