if (FAILED(hr))

You already mentioned this. I asked what the error is that you are receiving. Have you stepped into the Open() method to see what the problem might be?

//->Get the application path for the database
CString app_path=GetModuleLoadPath();
Use this code u will get the file name in the
format as (D:\\PMR\\vc++\\conndevices.mdb)

GetModuleFileName is only Function that can reterive file path for you..

When I click a tab page I want to be able to set a flag to indicate to the system that this page has been visited.
Something like OnGetFocus(). Does such a funciton or something similar exist?
Basically when a page gets focus it needs to ensure that any activity on its sister page has been saved before it can proceed, so the sister page will need to have set something

Hi
I have done something like that before... the information on the previous tab needs to be save when another tab is selected.. this is what i have done...
1. Create a variable to store the selected tab...
2. Use OnClickTab to find out which is the newly selected tab...
3. Check if different from last selected tab - if true... prompt save and save previous tab...
4. Refresh the information on the new tab...
5. Save new tab selection to variable
I hope this helps...

OnClickTab - Now that sounds like a very good idea. I'll try it out...
Thanks

A page will have an invalid window handle until it has been visited at least once.

This is what OnKillFocus() is for.

How to know whether the sound card is an 5.1/7.1 channels audio supported card by code?

can someone please explaing what type is UINT_PTR. Is it pointer to unsigned integer or just an alias for unsigned integer? 
after looking in basetsd.h file I found it is defined as :
typedef _W64 int INT_PTR;
so it seems it is unsigned integer, but then why people at microsoft has choosen such an ambiguous name for it or is it just PTR doesnt mean pointer and I am misinterpreting it. 
thanks

Like Johann said, it's used to treat a pointer as an UINT. There's INT_PTR, which treats the pointer as an INT and so on.
Pretty useful for writing platform independent code. Simply casting a pointer to unsigned int won't work on a 64 bit platform, for example.

There is 2 definitions for UINT_PTR:
if _WIN64 is defined it is a unsigned __int64 (a integer on 64 bit)
if not it is defined as an unsigned int (a integer on 32 bit)
