To close an application just write
PostQuitMessage(0);

I have written my own strlen() function called my_strlen(). I works quite well.
int my_strlen(const char *source)
{
int len = 0;
while(*source)
{
len++;
*source++;
}
return len;
}
Now my question is:
Which function ist faster, my version, or the asm-version of the original strlen?
thanks

The original one is faster...
You could also make your own faster like this:
int my_strlen(const char *source)
{
char *old = source;
while(*(source++) != '\0');
return source - old;
}

What is the proper way for my VC++ app to read entries from the outlook address book, if there is one on the system?
Do I have to use office-type COM objects or is there a better way to do it?
Thanks

Which version of Outlook? Outlook Express? Outlook 97/98/2000 or XP. Are the entries stored on Exchange or in a .PST.
With Outlook 97/98/2000 you can use extended MAPI. I think with 2000 you can use CDO but have not tried it yet. As for XP, don't know - not got it yet.
I'm not sure if the office COM objects will be much use in XP or 2000, I think the security patches stop external apps from reading the address book. Or at least it will pop up a message asking for a users authorisation to access the address book.

Hi,
I am using the CHtmlView->InsertAdjacentHTML to add DHTML to the body of the document im displaying and I have three problems
1) Im adding anchors with OnMouseOver events attached to the links, these are not being displayed on the inserted HTML.
(I need to make the IE engine re-parse the document)
2) Although new HTML has been added to the page it is not displayed unless I move the mouse over the window.
(but the first insert displays immediately, subsequent ones need mouse event)
3) Often when I scroll the window whilst HTML is being added by a background thread, the text/gfx seem become lost and a page refresh produces a blank screen but input-boxs are still visible?.
(i am using GetBusy() to wait before inserts)
Hope someone can help

I have read with interest the article CODBCRecordset for reading data from
an excel spreadsheet.
My problem is that this appears to work intermitenly. I have a spread sheet with formats of general but sometimes it will read in a others times it won't.
If I force the data types of the columns that doesn't appear to work.
Has anybody encountered such a problem before ? Any ideas

Does anyone know how I can find out what NT groups a user belongs to.
Given a domain and account name, I can get the user's SID but I would like to find out (recursively) what groups he belongs to. I need this so that I can walk a DACL to see if he has access to a given file. I would like to use GetEffectiveRightsFromAcl() but it appears to be totally broken (MSDN sez that it fails under NT4 SP4 and SP6; my testing shows that it has problems under W2K as well). My code works fine for user SID's but obviously I need to take into account group memberships as well.
As an aside, I also tried getting a token (via LogonUser()) and calling AccessCheck() which works fine for files that have no security assigned. When I try to assign an ACE (via Explorer), AccessCheck() fails with ERROR_INVALID_SECURITY_DESCR ("The security descriptor structure is invalid").
HANDLE hToken ;
DWORD rc = LogonUser( pUserName , pDomain , pPassword , LOGON32_LOGON_NETWORK , LOGON32_PROVIDER_DEFAULT , &hToken ) ;
assert( rc ) ;
HANDLE hFile = CreateFile( "d:/tmp/junk" , GENERIC_READ , 0 , NULL , OPEN_EXISTING , FILE_ATTRIBUTE_NORMAL , NULL ) ;
assert( hFile != INVALID_HANDLE_VALUE ) ;
SECURITY_DESCRIPTOR* pSD ;
ACL* pACL ;
rc = GetSecurityInfo( hFile , SE_FILE_OBJECT , DACL_SECURITY_INFORMATION , NULL , NULL , &pACL , NULL , (void**)&pSD ) ;
CloseHandle( hFile ) ;
assert( rc == ERROR_SUCCESS ) ;
DWORD desiredAccess = FILE_READ_ATTRIBUTES ;
GENERIC_MAPPING genericMapping ;
PRIVILEGE_SET privilegeSet ;
DWORD privilegeSetLen = sizeof(privilegeSet) ;
DWORD grantedAccess ;
BOOL accessStatus ;
rc = AccessCheck( pSD , hToken , desiredAccess , &genericMapping ,
&privilegeSet , &privilegeSetLen , &grantedAccess , &accessStatus
) ;
assert( rc ) ;
cout << "AccessStatus=" << accessStatus << endl ;

Kinda. They return the group names, not SID's and are a total pain in the ass to work with; you have to everything twice, once for networked groups and once for local and they only work with Unicode strings. I was hoping for some function that I could just call and it would return a list of SID's.

What about GetTokenInformation with TokenGroups as TokenInformationClass?

Hi All,
I have a problem with disconnected recordsets.I have a component.One if it's function will get the selected Records in a Database.I am passing the Recordset pointer from the server to the Client.I am using disconnected
recordsets for this.
I can see that at the server side I am getting the Recordset
pointer.But, I could not get this pointer on the client side.
the function has the protoype
STDMETHODIMP GetSpecificElements( [out] IUnknown **ppRecordset);
I could get the Recordset pointer at the server side, but could not pass it to client.I am using Client side cursor(adUseClient) and standard
Marshaling.I am using some user defined classes inside this function to Open Database and get the Recordset Pointer .I could get the Recordset Pointer inside these classes , but failed to get
this pointer from this function to client .Does the Disconnected Recordsets vary between ADO and ADOX ?
what could be the problem ?
Thanx in advance for the help.
Regards,
yamini

Hi! I'm trying to write a multi-lingual dictionary program in MFC. It's my first *real* Windows program and I'm sorta stuck on a problem. I was wondering if anyone could tell me how to get a CDocument pointer from inside a dialog class. If anyone could help I'd really appreciate it if you could e-mail me at Taluesin3@juno.com. TIA

Hi,
Is it possible to use a tree control in a dialog to get the following comportment:
when I select an item, the dialog changes his controls a similar way of a Tab control or property page ?
Thanks,

Yes, it's possible. Handle the TVN_SELCHANGED notification and change the contents of the dialog.
