Does this work?

CDatabase *pDatabase = new CDatabase();
pDatabase->SetQueryTimeout(30);

test m_test(pDatabase);
m_test.m_strFilter="Select Field1, Field2 from Table";
m_test.Open();

delete pDatabase;

Well, that was simple enough. I was looking to change it for the whole structure. Guess I was over-complicating it. Thanks much!

How the hell did you figure that one out! Dude that is like a puzzle inside a box inside a trunk inside a shark inside a whale inside a theme park located on the internet that you can't find on Google because you can't figure out the keywords to use!

It wasn't quite as easy as I made it look Poke tongue | ;-P

I had to look at the source code, since the docs[^] make it seem like
one can use the CRecordset::m_pDatabase variable to do this.
Problem is, this variable isn't initialized/created until
a query is performed, so that code seemed simpler than messing with
a CRecordset derived class.

I've personally never used the NULL CDatabase method - it's
more efficient (and easier to control) a manually created CDatabase
object and pass it in to CRecordset.

So when the user clicks on it they can't expand the tree to see the child nodes? Then what's the point of even having the Tree Control?

Which is what I showed. If, however, you need the dialog to be otherwise visible, see here, and here (about 3/4 way down).

In the future, please explain all of your requirements up front so that we do not provide you with less-than-helpful suggestions.

You make your main application window a child window of a hidden parent window.

stdcall_api & troubles

Hello,

Being a very noob at c++, i managed to screw it up completely with this little piece of code

#define stdcall_api __stdcall

Now, at the time, i did not know this would hurt me in so many ways that would make the Spanish Inquisition proud, but apparently this had the effect of generating me 272 errors , all located in winnt.h and winbase.h, in all my Visual c++ 2008 projects that i have and need to build.
My question is: can i get my projects building again?
Thank you very very much,
A noob @ c++

just a guess, in what order are you #including your headers, and where do you #define you stdcall_api ?

You probably meant the other way around since __stdcall is a reserved word, i.e. you want the identifier stdcall_api to be substituted with __stdcall during the preprocessing phase, right?

The errors you got are from the windows header files wherever __stdcall is substituted by stdcall_api which is an unknown identifier.

Do it like this:

#define __stdcall stdcall_api

Forget that the above ever existed, it's embarrassing.
