It must be the only one...
Thanks for writing in portuguese. By the way: the correct spelling is "tudo". Tudo bem por aqui também!

Hi,
does anybody know,
why the virtual OnReceive() function is not working
on WinCe 3.0 (Pocket PC 2002)?
I'm using the CSocket class in a MFC Application.

Hello,

All of you guys who had developed ActiveX controls for Embedded platforms to please look at the thread Windowless ActiveX Control at the VC++ ATL / WTL / STL discussion board. Thank you guys.

Hi,
does anybody now, how to change background color of a treeview?
I'm working on WinCe 3.0, so I cannot use TreeView_SetBkColor Macro....

João Paulo Figueira17-Feb-03 22:00

Did you try to use the custom draw service? This envolves handling the NM_CUSTOMDRAW message. It will allow you to customize the drawing of the tree in a number of ways.

Ortie17-Feb-03 23:09

17-Feb-03 23:09

Yes, I tried it, but I can just set the TextColor and TextBkColor, not the Background Color of entire window. SetBkColor function and selecting a brush to device context doesn't work. The best result I've archived is to fill entrire window's rectangle using FillRect(). It works fine, but there still remain white areas nearby icons and nodes. I may be able to paint them using SetPixel, but that's
pretty dirty technique, in my opinion. Is there any other chance?

Maybe all you need to do is intercept WM_ERASEBKGND and use your own brush.

Ortie19-Feb-03 6:38

19-Feb-03 6:38

Unfortunately, this doesn't work too.
The white areas are painted after the background paint. And they are always
white, even if you set different color for window background for entire Windows (in Control Panel ->Display Settings)

Anyway, thanks for effort.

Thanks for the links. A couple more questions if you don't mind,

1. Do you recommend WTL or MFC for CE dev (not work related, just hobby)?

2. Do you have links to good docs on WTL CE development ?

Thanks in Advance

PocketPc 2002 - Emulator Release ActiveX Control

17-Feb-03 1:37

MFC is far more documented than WTL. It will generate bulkier executables, and its whole architecture is less elegant than WTL's. The problem with WTL is the lacking of an "official" documentation. But you can always find WTL docs on the web. You can start here in CP or go to the following sites:

http://www.idevresource.com/wtl/[^]

http://www.viksoe.dk/wtl/[^]

http://63.193.123.11/wtl/[^]

Re: PocketPc 2002 - Emulator Release ActiveX Control

13-Feb-03 7:35

Hello All,

I'd never thought about that before Sleepy | :zzz:

. I want to distribute an ActiveX control for Pocket PC, nevertheless I will also distribute three versions of that component: Emulator Release, Desktop and Device Release, ok till here?
The developer will use those versions to build his application on my component, but where in the name of Jesus Christ he'll put my Emulator Release to start testing Confused | :confused:

? Inside the respective Emulation directory under Windows CE Tools folder...I don't think so!!!
Try to test this...start your emulator and create a simple doc file and save it, and seach for it in your computer. File not found, isn't it Cry | :((

? So what?
There's a huge *.bin file Confused | :confused:

in the emulation folder, is everything within?

How about eVC>Tools>Remote File Viewer?

That allows you to import and extract files between (emulation) device and desktop. Once there, you can use regsvrce on the device to register the component as normal.

Protecting COM Component against copying

Raphael Amorim11-Feb-03 9:39

Re: error LNK2019 in eVC++

11-Feb-03 9:39

Hello all,

I'm facing this problem: I got some COM components (not OCX's) that I
want to protect against copying and the whole process is based on three
machine configs. :
a physical, a logical and a random configuration. Basically they're:
Processor ID, HD volume signature and a Cryptographic key pair respectively). There's a *.lic license file that is signed by me, and got all this configs and the serial number. The COM component (Emulation) must check out this file to verify if was signed by be(ownership) and if corresponds to the developing machine. The COM component (device) checks only the ownership. but my problem is: How to get those machine informations from the Emulator component? I also thought about set the Emulation registry with those machine informations from the Desktop machine, but I really don't know how to perform it!! Big Grin | :-D

Thanks for any help,

Hi, Recently I have been working on this server-client side application, using single doc with Doc/View. In fact, I am using the sample eVC++ application called chatter.
I only added this code below->

void CVoiceRecorder::OnVoiceRecorder()
{
// TODO: Add your command handler code here
CM_VOICE_RECORDER cmvr;
memset( &(cmvr), 0, sizeof(cmvr));
cmvr.cb = sizeof (CM_VOICE_RECORDER);
cmvr.dwStyle = VRS_NO_MOVE;
cmvr.xPos = -1; //-1 means control is drawn centered to Parent window hwndMain
cmvr.yPos = -1;
cmvr.hwndParent = m_hWnd;
cmvr.id = NULL;
cmvr.lpszRecordFileName = TEXT("\\My Documents\\TestRec.wav");
DeleteFile(L"\\My Docuemnts\\TestRec.wav");
DeleteFile(L"\\My Documents\\~Rec_0.wav");
HWND hwndVoice = VoiceRecorder_Create (&cmvr);
::ShowWindow(hwndVoice, WS_VISIBLE);
::UpdateWindow(hwndVoice);
}

I am trying to display the voice recorder control, but Embedded VC++ gave me this error->

"CVoiceRecorder.obj : error LNK2019: unresolved external symbol _VoiceRecorder_Create referenced in function "protected: void __thiscall CVoiceRecorder::OnVoiceRecorder(void)" (?OnVoiceRecorder@CVoiceRecorder@@IAEXXZ)"

What might it be? Thanks.
Eek! | :eek:

BUG: LNK2019 When Building For Pocket PC Emulation

SYMPTOMS

When building an application for Pocket PC emulation that uses the Windows CE operating system functions, errors similar to the following may be encountered:

<filename>.obj : error LNK2019: unresolved external symbol _CeDeleteDatabase referenced in function <function>

CAUSE

These operating system functions use the _stdcall calling convention, but the compiler is declaring them as _cdecl. This problem occurs with the Windows CE Platform SDK for Pocket PC because the functions are incorrectly declared in the Windbase.h file without a linkage type.

RESOLUTION

Use one of the following workarounds:

Add the /Gz compiler switch to the configuration's project settings when building for Pocket PC emulation.

If the first workaround prevents other functions/libraries from linking in your project, then modify the Windows CE database function declarations in the Windbase.h file. For example, for the error in the "Symptoms" section, change the following declaration
```
BOOL CeDeleteDatabase (CEOID oid); 
```
to read:

BOOL WINAPI CeDeleteDatabase (CEOID oid);

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article.

How to change menu caption

If you are using the PocketPC HTML control, you can set up a timer in the containing window, and have the timer handler send a navigate message to the control. Make sure that 15 seconds is enough to read in the full page.
