U can create COM Object only if it is successfully Registered.
If u r debugging in this way u cannot find out the installation problem.
u need to debug the DLL while registering it.

may be this is because infinite loop, deadlock in the registration path

Please read CPallini's reply again. He said:
The above is unusual. Could you debug your DLLRegisterServer function?
If your DLL isn't registering properly, then of course CreateInstance won;t work!
Regedit is also your friend - you can see if the keys you need for registration are being created.

if u don't know how to debug the DLLRegisterServer, following may be useful,
1) put a breakpoint in your DLLRegisterServer function
2) Set your COM DLL project as Startup project
3) IN your COM DLL project Settings set the values such that regsvr32.exe is started,
vsproperty->Debugging->Command = C:\WINDOWS\system32\regsvr32.exe
vsproperty->Debugging->Command Arguments = "$(TargetPath)" // path to COM DLL
4) start debugging

Hi,
its possible by using ado. In order to do let it work, you must preform some setup tasks.
1. Import the Library
place the following line in the stdafx.h file. the msado15.dll file should be located in the project directory.
#import "msado15.dll" no_namespace rename ("EOF", "adoEOF")
2. Initialize the ole lib
Ado works with oledb.
if(OleInitialize(NULL) != S_OK)
{
}
3. Connect to the database
Replace USER_ID, PASSWORD, SQLSERVERNAME, DATABASE_NAME with the correct values
CString strConnectionString;
strConnectionString.Format("uid=USER_ID;pwd=PASSWORD;driver={SQL Server};server=SQLSERVERNAME;database=DATABASE_NAME");
_ConnectionPtr ptrDbCon;
ptrDbCon.CreateInstance(__uuidof(Connection));
ptrDbCon->Open((_bstr_t)strConnectionString, "", "", -1);
<code></code>
You sould connect to the master database in order to create another database.
Just execute the queries to create an database as you need.

Have you tried using the CREATE DATABASE command?

But the error message you received mentioned 'myatble'.

If you are a beginner and really are willing to learn, then you should read some good books. Windows programming has a steep learning curve. I'd suggest you the following books:
Programming Windows (fifth edition) by Charles Petzold[^]
If you'd like to do some MFC, then Programming Windows with MFC (second edition) by Jeff Prosise[^]
There are other libraries like ATL, WTL and frameworks (including non-microsoft ones, like VCF, WxWidgets, etc,.). But then you'll have to decide what you want to learn.
Trying to learn any of the above will require you to have good understanding of OOP and working knowledge in C++.

I guess he want to uses of Win32 not MFC,maybe.

It is good you're helping out, but the tutorials are a little bit outdated. Also, I think starting from Visual studio 4 now is not a very good idea.
