I have some question about CADORecordset.
I've got the code like this:

void CAccessLayer::Repaint()
{
	CADORecordset rs(&g_db);
	CString Query;
	Query = "SELECT * FROM Points WHERE LayerID = "+m_LayerID;
	int X;
	int Y;
	if(rs.Open(Query,CADORecordset::openQuery))
	{
		rs.MoveFirst();
		for(int i = 0; !rs.IsEof(); rs.MoveNext(), ++i)
		{
			rs.GetFieldValue(_T("X"),X);
			rs.GetFieldValue(_T("Y"),Y);
			X=(_BitmapWidth*(_rotate*X - _ViewLeft))/_WR;
			Y=(_BitmapHeight*(_rotate*Y - _ViewTop))/_HR;
			_BitmapCanvas->Ellipse(X-100,Y-100,X+100,Y+100);
		}
	}
	rs.Close();

}

but i use this function very often, and i'd like to place the query in the constructor of the class. And i want to call in the function only this:

void CAccessLayer::Repaint()
{
                rs->MoveFirst();
		for(int i = 0; !rs->IsEof(); rs->MoveNext(), ++i)
		{
			rs->GetFieldValue(_T("X"),X);
			rs->GetFieldValue(_T("Y"),Y);
			X=(_BitmapWidth*(_rotate*X - _ViewLeft))/_WR;
			Y=(_BitmapHeight*(_rotate*Y - _ViewTop))/_HR;
			_BitmapCanvas->Ellipse(X-100,Y-100,X+100,Y+100);
		}
}

And in constructor i have this :

rs = new CADORecordset(&g_db);
CString Query;
Query = "SELECT * FROM Points WHERE LayerID = "+m_LayerID;
rs->Open(Query,CADORecordset::openQuery));

But my programm doesn't work. Is it necessery to have CADORecordset locally???
Thaks.

Is g_db initialized when the constructor is called?

Hi All,

I have an Inventory application running on the desktop(Developed using C#). I'm planning to write one for PDA( Using C# & .NET Compact Framework). But the issue is that, i want to synchronize data between the destop application and the handheld application.IR communication is not possible, as it is limited for a very short distance.
Can any one throw light on other communication options available( like GPRS, wireless etc..).

Thanks in advance

The Pocket PC does not support native console applications. You have download a third party console.

I use the File Open dialog from an article on CP, and it works fine when used form my app class.

Weirdness, Part 1 - In our app, we have a listview. One of the contxt menu items needs to call up this dialog box also. However, the dialog box displays, but locks up when called from the listview.

Weirdness, Part 2 - If I put a call to AfxMessageBox in the dialog's OnInitDlg() function, the dialog box works fine after I dismiss the message dialog. If I don't display the message dialog, the dialog box locks up.

Weirdness, Part 3 - The "X" button in the titlebar doesn't work, but the SIP does, and I can dismiss the dialog box by clicking the ENTER key in the SIP.

Anyone have any hints?

Are you using property sheet/pages and dialogs, or just dialogs ?

They all sound like the same problem - the new dialog isn't getting the focus when it should.

I've had something similar happen when, for instance, i created a dialog resource as a property page, then changed my mind and used as a CDialog without changing the resource properties from child to popup. Also make sure the new dialog isn't overlapped, i think that only the main app dialog can safely be overlapped (cound be wrong - have't checked).

For Part 3 : the X is part of the dialog/page, the SIP isn't, hitting enter in the SIP just acts as if you hit the default button on the dialog/page - usually IDOK.

On an unrelated note, here are some other things i've found :

There is a bug in MFC CPropertySheet::ContinueModal(), so in any PS derived class' override with :
class CkDlgEdit : public CPropertySheet
...
BOOL CkDlgEdit::ContinueModal()
{
if( !CWnd::ContinueModal() ) return(FALSE);
return(TRUE);
}

There is a resource leak when displaying a dialog box. The following methodology evidently prevents this :
void CJsoFldCeDlg::OnDblclkList( NMHDR *pNMHDR, LRESULT *pResult )
{
...
{
CkDlgEdit dlg(this, L"Edit Observation");
dlg.DoModal();
}
AfxGetApp()->OnIdle(1);
...
}

Try inserting this on the OnInitDialog handler right after the call to the base class' handler:

Web Services on the Pocket PC with .NET Compact Framework

I've had a search around and I'm at a bit of a loss... So here goes...

Background: I have a Pocket PC application that creates XML files. The PPC application reads and writes them using XmlTextReader/Writer. These files can be synchronised through ActiveSync and a desktop application allows the data to be reviewed before going in to the database.

Situation: Now, the data is to communicate with a Web Service. Since I already have the XML structure defined is there anyway I can put that across to the server without ending up with lots of > and < etc.? At the moment I define the data type in the Web Service as a string and copy the contents of the file into the string and send it across.

Get rid of the authentification key in bluetooth

Hello!

This is not a programing question!!
I have a bluetooth device that is 'connected' to my pockett PC. When this device is started, it asks the Pocket for an authentification key. I want know to disable (or store this key somewhere) this step so it will be completely transparent for the end user.

Any idea of how to do this ?? (not by program because none of my programs are run yet). Is it possible to write something in the register ?
Thanks

Its been a while since I did anything with bluetooth, but (IIRC) if you pair the devices you should not have to enter an authentification key.

Any idea ?

As I said, Its been a while and maybe someone with more recent experience can help you better. Here's how I remember the whole thing.

how to do it manually:
Atcivate the BT on both devices:
Let one of the devices connect to/find the other
Pair the devices by entering an autherntication key on both devices.
(you will have to do this atleast once, otherwise how can they know about eachother)
Now they should be able to communicate with eachother at any time without a key.

with code:
I dont really know. When I was playing with this 2-3 yrs ago it was very stack-dependent. That is, the api's to search, connect and pair BT devices was supplied by the stack implementor. There was no standard way to do this that worked with every stack/os with a BT device. I have no idea if that has changed.

Removing shortcuts from the start menu

I'm using Windows CE, PocketPC 2003.

The problem I have is, I need to remove all of the shortcuts from the start menu except for Settings and the shortcut to my program. This would be done preferably in our install file (using InstallShield Developer 8.0) but I can get it to call a .dll or a .exe or whatnot if needs be, so just any method of removing these shortcuts programmatically would be appreciated..

Thanks

enumerate the .lnk files in \windows\start menu with findfirst/findnext and then move the ones you dont want there to \windows\start menu\programs

Note: you might want to use SHGetSpecialFolderPath to find out the non-english names of these folders if your users have non-enlish pdas.

Programs, Settings, Find and Help are not removable (or atleast Programs and Settings, dont really know about the other two).
