Hi just a quick Query.

Is it possible to convert a Visual Studio 2003 workspace to a EMbedded C++ 4.0?

Is the only way restart the project from scratch and add the files from the VS 2003 project? I have VS 2003 which enables to me to create a "smart device" project for
C# and VB only Frown | :(

I would really like to port my VS 2003 workspace to the embedded platform but am unable to read it in embedded VC++.

Hey all,

I'm looking to program some simple Win32 applications on a PocketPC 2003 and I was wondering what you all suggest for intro material. I'd really like some documentation to step me through it all.

I've been doing .NET CF work for a while, but now I want to break into the real stuff. Does anyone have suggestions of resources to check out? I'm looking to use this as a way to break into Win32 programming for the desktop, so I'm not too familiar with that either.

The documentation in the SDK is sparse and hard to follow for a newbie like myself.

Thanks,
Adam

I've just started working on an app for a Pocket PC too. I haven't found anything that will
'step me through it all' (shame).

I started with an application from a Mobile Phone article on CP http://www.codeproject.com/ce/irdamobile.asp
and then got my own app working with what I had learnt.

These have been the most useful sites so far:-

And last but not least ....

I'm sure there are loads more if only I could find them! Have you found any useful sites?

How to scroll text in an edit control box in a dialog ?

I have an Edit Box in my dialog that I write various text into. When the text is larger than the Edit Box I want it to scroll. I added vertical scrolling to the properties and the bard appears OK but it is non-functional. Also when the text goes past the Edit Box size it does not scroll.

How can I get scrolling to work ??

Thanks

You have to go into the resource editor and tell set the correct properties for the edit control. I believe if you want it to wrap and scroll, you have to set the "wants returns" property.

Thanks but I have the want return, vertical scroll and AutoVScroll set and the text does not scroll.

I snapshot the text already in the Edit Box (if any) with GetDlgItemText(hWnd, IDC_EDIT3,textBuff,1024), then add the new text to it and use SetWindowText(hWnd,IDC_EDIT3 ,textBuff) to display the text to IDC_EDIT3.

The Vertical Scroll Bar is being updated (it changes size) but I cannot move it and the text is not scrolling down.

Any other ideas ?

Thx

I'm trying to port some ADO db code for use on PocketPC 2003. Is there a definitive explanation about what you need to do to make this a viable effort?

I have a machine with EVC3 installed, and was trying to use Joao's article, and it was importing the adoce31.tlb file, but I can't seem to find that file on my evc3 installation anywhere.

Thanks in advance.

Here's how I do it:

#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.

If i debug the application it shows COM port is opened successfully,number of Bytes written is also correct

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.

Problem in using Composite index in Seek method on OLEDB/SQL CE

AKSIVAKUMAR17-Jun-04 21:37

17-Jun-04 21:37

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
