Well, I tried that, and the compiler is complaining about _NewEnum. Here are the error messages:
<br />
adoce31.tlh(372) : error C2146: syntax error : missing ';' before identifier '_NewEnum'<br />
adoce31.tlh(372) : error C2501: 'IUnknownPtr' : missing storage-class or type specifiers<br />
adoce31.tli(16) : error C2065: '_com_issue_errorex' : undeclared identifier<br />
adoce31.tli(340) : error C2143: syntax error : missing ';' before 'tag::id'<br />
adoce31.tli(340) : error C2433: 'IUnknownPtr' : 'inline' not permitted on data declarations<br />
adoce31.tli(340) : error C2501: 'IUnknownPtr' : missing storage-class or type specifiers<br />
adoce31.tli(340) : fatal error C1004: unexpected end of file found<br />
Am I missing a step?

Here's how I do it:
#include <wceatl.h>
#include <comdef.h>
_COM_SMARTPTR_TYPEDEF(IUnknown, __uuidof(IUnknown));
void __stdcall _com_issue_error(HRESULT m_hr);
void __stdcall _com_issue_errorex(HRESULT hr, IUnknown *pUnkn, REFIID riid);
#import "C:\Windows CE Tools\wce300\Pocket PC 2002\dataaccess31\target\arm\adoce31.dll" rename_namespace("ADO") rename("EOF", "EndOfFile")
using namespace ADO;
You will have to define your own error handler in _com_issue_errorex.

Many thanks, that cleared up that particular set of issues. Now, I'm in a proprietary file form of hell. If I find my way out, I'll let you know.

Hi all,
I want to write the data to COM Port using embeddedVC++ 4.0 .But nothing comes on COM port, code is as follows.
If i debug the application it shows COM port is opened successfully,number of Bytes written is also correct
Do i need to do some settings in emulator to make it connect to com port??
same code works fine in VC++6.0.
////
wchar_t rightString[80];
wcscpy(rightString,_T("Hello"));
DCB m_DCB;
m_DCB.DCBlength = sizeof(m_DCB);
m_DCB.BaudRate = 9600;
m_DCB.ByteSize = 8;
m_DCB.fBinary = TRUE;
m_DCB.Parity = NOPARITY;
m_DCB.StopBits = ONESTOPBIT;
m_DCB.fParity = TRUE;
m_DCB.fNull = FALSE;
m_DCB.XonChar = 0x11;
m_DCB.XoffChar = 0x13;
m_DCB.XonLim = 80;
m_DCB.XoffLim = 200;
m_DCB.fAbortOnError = TRUE;
m_DCB.fOutX = false;
m_DCB.fInX = false;
HANDLE m_hPort = CreateFile(_T("COM1:"), GENERIC_READ |
GENERIC_WRITE, 0,NULL, OPEN_EXISTING, 0, NULL);
SetCommState(m_hPort,&m_DCB);
if(m_hPort == NULL)
AfxMessageBox(_T("Can not open port"));
else
if(WriteFile(m_hPort, rightString, 10, &BytesWritten, NULL))
AfxMessageBox(_T("Successfully written"));
CloseHandle(m_hPort);
///
Thanks in Advance

HI
My experience is that the emulators do not connect to the COM ports, you must test on a real device. Make sure you get a device that supports RS232 serial connections !! I found out the hard way that some do not ! Dell Axim X5 does and the HP IPAQ 4000 series and above should also.

HI,
I use the OLEDB method to seek the record:
...
TableID.eKind = DBKIND_NAME;
TableID.uName.pwszName = (WCHAR*)TABLE_TBL1;
IndexID.eKind = DBKIND_NAME;
IndexID.uName.pwszName = L"idx_Key";
...
// Set the Fld1 and Fld2 data to the pData
//
...
// Seek for the first row where the value of the selected column
// is dwEmployeeID.
hr = pIRowsetIndex->Seek(hAccessor, 1, pData, DBSEEK_FIRSTEQ);
if(FAILED(hr))
{
goto Exit;
}
However the Seek function does not working properly.
....
From the calling palce the client will pass like index, value1, value 2 and value3...based on it i need to seek and get the data.
Anyone know how to seek using composite index?
Thanks

Hi all,
I need to write application in Pocket PC. It is about using showing video on screen from web cam. I had free the buffer, but the "out of memory" dialog still pop up after 2 minutes....
unsigned char *pbuffer=(unsigned char *)malloc(m_Width * m_Height*6);
unsigned char *rpbuffer=(unsigned char *)malloc(m_Width * m_Height*6);
//this is allocation of memory
free(pbuffer);
pbuffer = NULL;
free(rpbuffer);
rpbuffer = NULL;
//this is the code of free memory
please help.......................
p.s. I am using eVC++ 4.0 on PPC 2003....

I use embedded visual c++ to write a video cam software, so that the pocket PC show the screen of the cam. But my menubar does not work.(I tick the top up box) When I click the top up button in menubar, the menubar hangs. But the screen still can show the video.
void CGroup7Dlg::OnPreview()
{
unsigned char *pbuffer = (unsigned char *)malloc(m_PrvWidth * m_PrvHeight * 3);
unsigned char *rpbuffer = (unsigned char *)malloc(m_PrvWidth * m_PrvHeight * 3);
if ((PreviewFrame((unsigned char*) pbuffer)) == false)
AfxMessageBox(_T("Preview Frame Fail!"), MB_OK);
Rectify(pbuffer, rpbuffer); //<----- a
CBitmap bitmap;
bitmap.CreateBitmap(m_PrvWidth, m_PrvHeight, 1, 24, rpbuffer);
CVOImage image;
RECT pic_rect;
m_picture_window.GetWindowRect(&pic_rect);
HDC picDC = ::GetDC(m_picture_window.m_hWnd );
CString path_fname;
::WriteBitmapIntoJpegFile(TEXT("\\pic1.jpg"), 80, (HBITMAP)bitmap);
UpdateData(true);
path_fname ="\\My Documents\\pic1.jpg";
image.Load (picDC ,path_fname );
image.Draw (picDC ,2,13 );
free(pbuffer);
pbuffer = NULL;
free(rpbuffer); //<-------b
rpbuffer = NULL;
}
There will be out of memory if I comment out line b but menubar works. There will be no problem but the screen pixel is in wrong order of course. I don't know how to fix this bug. Please help...

Developing apps for PPC2003 using EVC++ 4.0...
What happened to the old emulator. The 4.2 emulator doesn't resemble a PDA at all.
Is there a way to get the old emulator? Will it work?
Thanks in advance.

Are you targeting the POCKETPC 2003 or the STANDARDSDK? The PPC 2003 emulator rocks!

Well, it's set to standardsdk_420, but I haven't found a way to change it, and I didn't see anything during install about pocketpc2003...

Hi all,
I'm trying to programmatically remove or disable the Remove Programs options in start->settings.
A lot of the settings are contained in registry keys which I can disable but Remove Programs doesn't seem to be.. I was thinking about either removing whatever it is, or writing a stub program to overwrite it on the installation of my software.
Either way, does anyone know where/what it is? Is it an executable or a key or what?
Thanks!

Hi all~
How to add tag pages which place on the top of the tag control?
Also, can the location of the tag control not be started at the top corner(0,0) of the form? I cannot change the location. It changes back to (0,0) if I change it.
thanks~

If you find code warrior , J2me or Visual Studio are too complicated and you feel that you need to learn just one tool that is a lot easier, instead of three then, look up the Mobile Application development tool called GoDb which is similar to VB in look and feel but allows you to create Powerful Mobile Applications for PALM, POCKET PC, Symbian , Nokia. The tool comes with it own IDE , Gbasic - a language similar to VB ( infact if you know VB you can start programming in it instantly) and Simulators and Sync server .

Hi all,
is dynamic loading of appDomains also work in compact framework .net ?
I have run example in dynamic loading in .net framework,
but since compact framework dont have AppDomainSetup Class,
so what can I do ?
The code in dynamic loading in .net framework is in
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncscol/html/csharp05162002.asp
but when the port the code to compact framework, the code doesn't work coz AppDomainSetup Class is missing in .net CF.
Can anyone point to sample code or articles on it ?
Thanks

Hi all,
I've run into a little problem, I'm drawing a zone on a CDC and would like to fill the zone in with a colour, most likely black.
I collect the points and store them in a CArray of CPoints and draw the zone like...
<br />
typedef CArray<CPoint, CPoint&> CPointList;<br />
CPointList Points;<br />
<br />
<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{ <br />
for(int i=0;i<numPoints-1;i++)<br />
{<br />
pDC->MoveTo(Points.GetAt(i).x, Points.GetAt(i).y);<br />
pDC->LineTo(Points.GetAt(i+1).x, Points.GetAt(i+1).y); <br />
}<br />
}<br />
This just draws the zone, I did try using Polyline() and PolylineTo() but the starting point is always coming from the side of the display instead of the first point in the array, the code I used with the Poly methods was something like...
<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{ <br />
CPoint* pts = new CPoint[numPoints];<br />
<br />
for(int i=0;i<numPoints-1;i++)<br />
{<br />
pts[i].x = Points.GetAt(i).x;<br />
pts[i].y = Points.GetAt(i).y;<br />
}<br />
<br />
pDC->MoveTo(pts[0].x, pts[0].y);<br />
pDC->PolylineTo(pts, numPoints);<br />
<br />
delete [] pts;<br />
}<br />
and even with PolyPolygon() i got very strange drawings using the following code
<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{ <br />
CPoint* pts = new CPoint[numPoints];<br />
int tmp[2];<br />
<br />
tmp[0] = numPoints;<br />
tmp[1] = numPoints;<br />
<br />
for(int i=0;i<numPoints-1;i++)<br />
{<br />
pts[i].x = Points.GetAt(i).x;<br />
pts[i].y = Points.GetAt(i).y;<br />
}<br />
<br />
pDC->PolyPolygon(pts, tmp, 2);<br />
<br />
delete [] pts;<br />
}<br />
If anyone has some input which could help I'd be very intrested to hear it. Also I'm working with the PocketPC SDK so things like FloodFill() cant be used ;(

No, they can't be used. But they can be implemented...
QA: Where is the DC FloodFill method?[^]
Have fun!

Thanks João,
I have since added the class to my project but have run into a little problem.
My project has 2 CDC's, one is in the main View class and the other I use in my Zoning Class.
When I draw my zone I draw the zone on both CDC's but the second CDC in the Zoning Class will get filled in.
I then use this CDC as a hidden CDC to check if I'm still in a zone, using the likes of GetPixel() to find out if I have left the zone.
My problem now is that it's always returning true, as in I have left the zone, so I now need to display the second CDC to the screen to verify that the zone has been set up right, but when I do I just get a blank display, all white.
I'm using code like the following...
<br />
ColorZone = new CDC();<br />
ColorZone->CreateCompatibleDC(NULL);<br />
int numPoints = Points.GetSize();<br />
<br />
if(numPoints>1)<br />
{<br />
for(int i=0;i<numPoints-1;i++)<br />
{
ColorZone->MoveTo(Points.GetAt(i).x, Points.GetAt(i).y );<br />
ColorZone->LineTo(Points.GetAt(i+1).x*, Points.GetAt(i+1).y);<br />
}<br />
<br />
if(CZone::IsComplete)<br />
{
CPoint point = Points.GetAt(0);<br />
point.x+=1;
point.y+=1;<br />
CRect rect;<br />
GetClientRect(NULL, &rect);<br />
CFloodFill<CDC, COLORREF> flood(*pDC, rect);<br />
flood.Fill(point, RGB(255, 0, 0));<br />
<br />
CMyBaseView* pView = (CMyBaseView*)((CMainFrame*)AfxGetApp()->m_pMainWnd)->GetActiveFrame()->GetActiveView();<br />
pView->GetDocument()->mapDC = ColorZone;<br />
}<br />
}<br />
As I'm very new to PocketPC development I'm a little unsure if the above code should do what it's meant to be doing, any input would be grateful!
Thanks again,
ar
