Get free disk space of PDA from PC via RAPI

Does anybody know, how to get the free disk space using RAPI, even in case of storage cards.

CeGlobalMemoryStatus does not provide enough information.

I'm out of ideas.

With best regards

I think you'll have to write a DLL for the device which calls GetDiskFreeSpaceEx, and invoke it from the desktop with CeRapiInvoke.

The Pocket PC 2002 SDK includes a sample called CeInvoke, typically located at C:\Windows CE Tools\wce300\Pocket PC 2002\samples\win32\Ceinvoke.

Thats the way i tried to avoid, but this seems also to me the only possible solution.

Show Unicode text in CCeCommandBar menu ?

LOGFONT lf;<br />
   memset(&lf,0,sizeof(LOGFONT));<br />
   _tcscpy(lf.lfFaceName,_T("Arial"));<br />
   lf.lfHeight=18;<br />
   m_font.CreateFontIndirect(&lf);<br />
   m_wndCommandBar.SetFont(&m_font);<br />
   m_wndCommandBar.Invalidate();

Why can't I set font to CCeCommandBar variable ??? I want my menu have some characters in Vietnamese (Unicode) but something's wrong there. And another thing is that I can't input Unicode text in Resources. (I tried to input like \x1ea3... but also failed)

Converting BSTR/CString to _bstr_t

Does anyone know how to convert BSTR/CString to _bstr_t

The _bstr_t constructors accepts both const TCHAR * and BSTR, so it should be direct:

CString  strOne(_T("One"));
_bstr_t  bstr(strOne);

I'm getting this error:

error LNK2019: unresolved external symbol "void __cdecl _com_issue_error(long)" (?_com_issue_error@@YAXJ@Z) referenced in function "public: __thiscall _bstr_t::_bstr_t(unsigned short const *)" (??0_bstr_t@@QAE@PBG@Z)

Any suggestions?

Yes. You have to declare this function in order to trap COM errors. This function will only be declared once. You can use the following:

void __stdcall _com_issue_error(HRESULT m_hr)
{
	TCHAR pcszError[1024];

	_stprintf(pcszError, TEXT("_com_issue_error(%ld)\n"), m_hr);
	OutputDebugString(pcszError);
}

I'd avoid _bstr_t altogether. Use ATL's CComBSTR. It's smaller.

Can't establish connection to Pocket PC

I first had an older iPaq connected via it's cradle/usb. I went out, bought a new iPaq, installed ActiveSync 3.7 (after un-installing 3.5), now Visual Studio .NET 2003 can't establish a connection to the new iPaq.

What's with that?

Thanks!

Does ActiveSync 3.7 see your new iPAQ?

Yes it does, however vs.net 2k3 does not. It did see it when I was using my old iPaq w/ AS 3.5. I uninstalled that and installed AS 3.7 to accomodate w/ my new iPaq.

Now vs.net won't recognized my pocket pc device. This means I don't have debugging capabilities, which really, really bites. WTF | :WTF:

Thanks!

... and reinstalling vs.net must be out of the question, right? Try to ask this question in www.pocketpcdn.com. There is a .Net-specific forum. Good luck!

It's not entirely out of the question, however that's not something I'm at all interested in doing. There is no guarantee that it will solve the problem and it may end up causing new and unexpected problems that I don't have time to deal with right now (big deadlines coming up.)

Thanks, I'll try the folks there.

Try using ADOCE. The type library is available in the adoce31.tlb file. You can use the #import directive on this file.

There is an article on the Database section on creating ADO classes. You can adapt it to ADOCE. There are a number of database resources here: Pocket PC Developer's Network[^].

Hi, Thank you for helping me before( i speak about CDC Smile | :)

).
Now i have another problem - this time with database. I've red a lot of materials about databases on Pocket PC, but still have some problems, for example where can i find this file : adoce31.tlb. And another one question - i've loaded one example of database using with ADO, and can't execute it on my Pocket. Thank you very much.

I believe this file was available on older versions of the Pocket PC 2000 and 2002 SDK. Check this:

Missing ADOCE31.TLB?[^]

If you are using Pocket PC 2003, the cdb file format has changed. You will have to re-synchronize the mdb file.
