I'm trying to retrieve the Datbase Name, Server Name, and, if Oracle, the Net 8 Name set in an ODBC DSN without first opening the ODBC Connection. The idea is for the user to specify an ODBC DSN and the application will get the information about the DSN to open an ADO Connection. The only way that I've found to retrieve this information is to first open the connection using ODBC. This seems like an very inefficient way to get the information. I know that i can retrieve if from the registry, but that way has already been shot down by my supervisor. Preferabley I need to get it from some kind of Win32 API call. Anybody have any idea how to do this? ...

What unmanaged VC++ ADO objects are there, and what is there header file? JD

I recently switched from VS6 to VS.Net for writing unmanaged C++. I noticed they took away the Wizard to derive a class from a CRecordset and wrap it around a table. I only know how to access database using CDatabase and CRecordset (or a class derived from them). I am guessing that the idea is to get away from ODBC and to start using OLE or ADO. I found an article in a book describing a set of classes CADOConnection and CADORecordset. I cannot find neither of them mentioned on MSDN, so my first questions is does anyone heard of and used these classes and if so is there any documention on them. My Next question is what alternatives does anyone else like to use instead of CRecordset? I know that OLE is faster than ADO, but is that much faster and is ADO that much easier to use? One last question, for anyway using generic CRecordsets, what is the easiest way to tell if a field is null, I know i can do it from a class that is derived and has teh DDX calls, but what about just a CRecordset? JD

Does anyone know how to derive from a DAO Recordset like the wizard in VC6? Does anyone know good places to get an addin like this? slack

Does anyone know where to get an addin that will automatically wrap DaoRecordsets around a Table? I miss this feature in VS.NET. or a better way of getting info from a DAO database? Keep Slacking, slack

why I try to add a resource useing the menu option 'add resource' the Visual Studio .NET IDE looks like its doing something then just dissapears. Has anybody seen this before or know what could be causeing it? I'm using it to write unmanaged VC++ and I added a registry explorer macro that i removed when this started to happen. Anybody got any ideas. I've checked all the knowledge bases i could find and can't find anything like it. Keep Slacking, slack

Does anybody know how to get the number of arguments from a variable length function parameter list? I can't seem to find any documentation anywhere about how to get then number or arguments, without the number of args being a parameter itself.

In Python there is a method called CPickle which will dump data structures into a binary file. that way many executables could share a data structure. It was accomplished using C. Does anyone know how this could be achieved for MFC's template data structures. -JD

Does anyone know of a way (I would guess it would use macro's) to execute a string which represents a line of code I want to execute. example: CString strCode = _T("int nVariable = 3;"); -And now execute it. I know it could be done with interpreted languages like python, but I don't know about C++. -JD
