but I always want the first 4 sections (best case) to be the same
No, because that's not how GUIDs are defined. The first 10 bytes are a counter (number of 100ns intervals since some date long in the past, plus some other stuff to account for daylight savings time changes) and the last 6 bytes are the computer's MAC address (or a synthesized number for machines w/o a network card). So you must not change the last 6 bytes on your own or you risk duplicating a GUID made on another machine.
If you can change your requirements so that the first part can be incremented, that's ok. You could then have:
51eb18c0-98a7-11d1-83d1-f46705c10000
51eb18c1-98a7-11d1-83d1-f46705c10000
51eb18c2-98a7-11d1-83d1-f46705c10000
and so on. (This is what the Guidgen util does, BTW.)

Either way (I was going on memory - I thought the first 4 parts were identical from a given machine).
In either case, I can't find UuidCreateSequential *anywhere* in the vs6 or sdk code. I checked the rpcdce.h file but that function prototype (or macro) is not defined.
I've run guidgen, and it generates completely different guid's every time (it uses CoCreateGuid).

According to the July MSDN
Windows NT/2000 or later: Requires Windows 2000 or later.
Windows 95/98/Me: Unsupported.
Header: Declared in Rpcdce.h.
Library: Use Rpct4.lib.
It's on line 1707 of rpcdce.h on my copy of the SDK ( which is always the most recent, unless the CD hasn't come yet ).

I guess I'm stupid - I wandered around for almost 30 minutes on the Microsoft web site and couldn't find a place to download the latest sdk.

I guess I'm gonna have to snag the msdn cd from work. I don't have any activeXcrement/jhava/plugin stuff turned on, so I can't download it.

Well, on the download page, which I posted the link to, there is links to .cab flies that you can download. Just good old plain files, that even Linux knows how to download

I snagged the June 2001 SDK CD from work. I have the correct RPCDCE.H files on my hard drive at work (installed February 2001 SDK a month ago), so I'm assuming that the June 2001 CD will have the same (or better?) files.
Thanks anyway Anders.

Hi..
I'm a newbie and I have a question...
these I do at the creation of X
int X[10] = {10,20,30,40,50,60,70,80,90,100,0};
but how can I Init X later in my program.
For Example:
int X[10];
int main()
{
X[] = {10,20,30,40,50,60,70,80,90,100,0}; // whats wrong with this line?
return 0;
}
|
|
|
|
|
int main()
{
for (i = 0; i < sizeof(x) / sizeof(int); i++)
x[i] = (i+1) * 10;
}
Should do the trick,

 ok so that's what you wanted to know.. i guess i thought too far ahead..
char *p="char *p=%c%s%c;main(){printf(p,34,p,34);}";main(){printf(p,34,p,34);}
Hard work has a future payoff. Laziness pays off now.

I think
int X[10]={10,20...,100,0} could also have been written as
int X[] ={10,20,..,100,0} with the compiler calculating the size of X at compile time..
Now i guess what you are asking is that why doesn't the compiler allow u to init. the way you have shown..right?
hmmm...well the answer is lurking somewhere in my head..just can't seem to put it into words..
Well it's the way the language was defined...but i don't see any harm in having a construct to initialize compound data structures at run time..
Although in your case X[] would refer to the base address of X..so the line defintely won't compile..
char *p="char *p=%c%s%c;main(){printf(p,34,p,34);}";main(){printf(p,34,p,34);}

I have a progrma now that uses ADO to read/modify/add to and delete records from a database.
My problem is two fold. First of all I want to create the database programatically, so I import ADOX like this:
#import "c:\Program Files\Common Files\System\ADO\msadox.dll" rename ("EOF", "adoxEOF")
Then I do this to create the database
HRESULT hr = S_OK;
ADOX::_CatalogPtr m_pCatalog = NULL;
ADOX::_TablePtr m_pTable = NULL;
try
{
TESTHR(hr = m_pCatalog.CreateInstance(__uuidof(ADOX::Catalog)));
char * pChar = new char[400];
memset(pChar, 0, 400);
sprintf(pChar, "Provider=Microsoft.JET.OLEDB.4.0;data source=%s;", (char*)DatabasePath);
m_pCatalog->Create(pChar);
delete [] pChar;
TESTHR(hr = m_pTable.CreateInstance(__uuidof(ADOX::Table)));
m_pTable->PutName("FileDatabase");
m_pTable->Columns->Append("FileName",ADOX::adVarWChar, 255);
m_pTable->Columns->Append("FilePath",ADOX::adVarWChar,255);
m_pTable->Columns->Append("FileLength",ADOX::adInteger,0);
m_pTable->Columns->Append("TimesDownloaded",ADOX::adInteger,0);
m_pTable->Columns->Append("LastModified",ADOX::adInteger,0);
m_pTable->Columns->Append("Frames",ADOX::adInteger,0);
m_pTable->Columns->Append("Seconds",ADOX::adInteger,0);
m_pTable->Columns->Append("Width",ADOX::adInteger,0);
m_pTable->Columns->Append("Height",ADOX::adInteger,0);
m_pCatalog->Tables->Append(
_variant_t((IDispatch *)m_pTable));
m_pCatalog->Tables->Refresh();
}
catch(_com_error &e)
{
_bstr_t bstrSource(e.Source());
_bstr_t bstrDescription(e.Description());
MessageBox(NULL, bstrDescription, bstrSource, 0);
return E_FAIL;
}
catch (...)
{
MessageBox(NULL, "General Error Creating Database", "Error", 0);
return E_FAIL;
}
return S_OK;
This works up to a point - the point I try to use it. It returns no errors and creates a file but neither my code or Access 2000 can read it. The other problem is if I create an empty table ( using Access ) this fails:
m_Connection.CreateInstance(__uuidof(Connection));
CComBSTR conStr = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=";
conStr.Append(DatabasePath);
bstr_t con(conStr);
HRESULT hr = (m_Connection->Open(con, "", "", adConnectUnspecified));
As soon as I add one dummy record, it succeeds.
So for now I must ship the Access DB with the program, I cannot create it, and the DB programatically ensures a dummy (meaningless) record exists and is hidden from the user. Surely this is not how it is supposed to work, so what am I doing wrong ?
Thanks

I have sorted out my ADO problem - apparently I need to check for a record count of 0 before calling MoveFirst();. Honestly, ADO seems designed to crash.
Anyhow, I'm still stuck on creating the DB from ADOX, and have been for some time, so any suggestions anyone has....

There is a great article located here:
http://codeguru.earthweb.com/controls/multiline_listbox.shtml
It has a simple CListBox with variable row height. Is there
any way of making an arbitrary row from that list viewable,
but unselectable??
Please, please, please, any response any one can give me will
be greatly appreciated.
Sincerely,
Danielle (an overworked graduate student)

Yes, you have to trap the incoming event, check the row and reset the current row if the one selected is an unselectable row.
Something like this should do the trick. You will need to decide what item should be selected if the one clicked is unselectable. You could just set it to the last one.
void CSelectList::OnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
if (IsUnselectable(pNMLIstView->iItem)
{
SetHtItem(iSomeotheritem)
}
*pResult = 0;
}
Ho[e this is of help,
Bill

You must do it in the function named OnItemSelChanging(NM_,
LRESULT *pResult), also, this is a member function of CListCtrl.
In that function, you should decide if the current item is the one you want to unselecting,and set the *pResult to 1.
///
{
if(XXXX)
{
*pResult = 1;
}
}

Okay, so I've got an IActiveDesktop instance, but whenever I call SetWallpaper, it sets a blank desktop instead of the image. But it's also returning S_OK. Any ideas...
Thanks,
- Mike
|
|

|

I just realize that maybe it's related to the Unicode string that SetWallpaper requires? I'm taking a LPSTR and casting it to a LPCWSTR. I can't figure out a way to test the casted string to see if it's right. How can I view a unicode string like that in something like a message box?
- Mike

You have to use a conversion routine to change from an LPSTR to a LPCWSTR see Technical Note 59 for more info
