Re: Problem with _Connection::Open() ! João Paulo Figueira7-Nov-03 2:58 João Paulo Figueira 7-Nov-03 2:58  Use a full path name on the connection string. The Pocket PC does not allow for relative path names, nor does it recognize a current directory. Check my samples: they all start with a '\'. Regards, João Paulo Re: Problem with _Connection::Open() ! nigs_krec7-Nov-03 3:13 nigs_krec 7-Nov-03 3:13  Hi there João, I have tried giving "Data Source = \\history.sdf" and have ensured that this file is present in the root directory (listed as "My Device" as seen from the file explorer in the pocket PC). Still the same problem persists. Could there be any thing else I can try ? Regards, Amit Re: Problem with _Connection::Open() ! João Paulo Figueira7-Nov-03 3:19 João Paulo Figueira 7-Nov-03 3:19  If you did set the correct provider, I can only guess that the file is corrupted. Use the SQL CE query analyzer to open the database file and browse it. Regards, João Paulo Re: Problem with _Connection::Open() ! nigs_krec7-Nov-03 3:48 nigs_krec 7-Nov-03 3:48  Hi João, I'm really sorry for the inconvenience I'm causing you with this. Please bear with me. Now after a lot of hardcoding it is finally working. The problem was with the parameter passing. My actual requirement is to create a number of connections to the database in the beginning itself and store them in an array so they can be used by a no. of threads. At present, after creating the first connection, when it attempts to create another, _Connection::Open() throws the exception "Cannot create a file when that file already exists". Is there some restriction with ADOCE ? Regards, Amit Help with linker error for &quot;vtMissing&quot; !! nigs_krec6-Nov-03 0:05 nigs_krec 6-Nov-03 0:05  Hi all, I am developing an application using eVC4.0. I'm getting a linker error saying "error LNK2001: unresolved external symbol "class _variant_t vtMissing". In one section of MSDN, I found that vtMissing is supplied by #import.

Regards, Amit Re: Help with linker error for &quot;vtMissing&quot; !! nigs_krec6-Nov-03 0:12 nigs_krec 6-Nov-03 0:12  I just realised...the adoce31.dll I am using is located is located under "Embedded Tools 3.0" directory and not the "Windows CE Tools" which comes with eVC4.0. There is no separate adoce31.dll with eVC 4.0. Could that be a reason ?

Nate Dialog Error VanHlebar4-Nov-03 15:24 VanHlebar 4-Nov-03 15:24  I have a dialog that is asserting during the OnInitDialog method. The framework is sending the dialog an nID=1. I don't have a single #define or a control that is defined as 1. The framework seems to be sending this nID value each time a dialog is opened. In most cases nothing happens, but in this one dialog it asserts during the ddx routines. Any ideas why on this one dialog asserts?

Regards, João Paulo Re: battery level notification ibiteu24-Nov-03 6:35 ibiteu2 4-Nov-03 6:35  I don't know what pooling is. Can you explain a little? Thanx Connie Re: battery level notification João Paulo Figueira4-Nov-03 6:39 João Paulo Figueira 4-Nov-03 6:39  Pooling means constantly looking for the info you want. This can be done by setting a timer (like the task manager - or NavBar - does) and, on each event, check the battery status. Regards, João Paulo Re: battery level notification ibiteu24-Nov-03 6:43 ibiteu2 4-Nov-03 6:43  Great Thanks for the info I'll start looking into it.

That's how I have it set up in my apps... but surely that can't be the only way? My timer message checks every 5 minutes, but even then, I think that's waste, especially when my "battery is low" value is 30%. It would make sense to subscribe to some notification system Oh well. It would also be nice to know when the device was going to be turned off. It's pretty easy to get the "device is turned on" notification, which is why I'm confused why there's no "device is going to be turned off" notification.
