Checkbox display on a tree is a control-wide setting. If you need customized drawing, take a look at this article:
QA: How can I change the background color of a Tree Control?[^]
Although the main purpose of the article is to show how to paint the tree background, it also shows you how to custom paint the entire tree.

thank you for your solution.. I have looked on your sample but I still have some problems. The issue is that my application is made using Windows CE Pocket PC 2003 Platform and it is not based on mfc. And if I try to use MFC classes( CTreeView ex or any class from Afxcmn.h library) the app throws me an exception because I belive it isn't supported. I found a solution:
HWND treeHwnd = CreateWindowEx (...);
TV_ITEM tvi;
TV_INSERTSTRUCT tvis;
HIMAGELIST himl;
HBITMAP hbmp
if( (himl = ImageList_Create(16, 20, ILC_COLORDDB ,1 ,CLR_NONE))==NULL)
{....}
hbmp = LoadBitmap(g_hInst, MAKEINTRESOURCE(IDB_CHECKBOX));
if((ImageList_AddMasked(himl, hbmp, RGB(0, 255, 0)))== -1){...}
DeleteObject (hbmp);
memset(&tvi, 0, sizeof(TV_ITEM));
memset(&tvis,0, sizeof(TV_INSERTSTRUCT));
tvi.mask = TVIF_CHILDREN| TVIF_TEXT | TVIF_IMAGE | TVIF_HANDLE|TVIF_STATE;
tvi.stateMask = TVIS_STATEIMAGEMASK;
//...
tvi.state = 1;
tvis.item = tvi;
TreeView_InsertItem(treeHwnd, &tvis );
TreeView_SetImageList(treeHwnd, himl, TVSIL_NORMAL);
my second problem is that when i try to do in the same way for having a second image near my checkbox bmp, this second one doesn't appear and I don't know what can be the problem.
Thank you again for the help given to me 
Regards,
Ramona

Hello there,
I am making a program that will need to be able to run in different countrys. And read ANSI files from different Codepages. Is there a way to programmaticaly change the locale of the system? I know on a PC you can change the locale on a per thread basis with SetThreadLocale, but that doesn`t seem to be supported by Windows CE.NET . So I presume I will have to change the system locale. Anybody has any ideas or knows how to handle this? Or is there a SetThreadLocale equivalent for windows CE.NET ???
Thx in advance,
Davy

In case anybody was curious. you can change the default codepage the system uses by changing the registry value HKEY_LOCAL_MACHINE\nls\DefaultACP to the codepage you wish to use. Offcourse you will need to make sure the codepage is actually supported by the system before you make that change. in the same key (HKEY_LOCAL_MACHINE\nls) you can change the system-locale.
Greetings,
Davy

Im writing this in desperation. Ive been given a project with the title of 'Develop an application for a Smartphone 2002'. Ive downloaded the embeded tools and the sdk for it. But thats were it all stops. Ive experience coding in VC++ and VB but cant seem to get any of this to go across to the emulator. When I try building a sample C++ program i get the msg
PsPCMonkey.exe - 0 error(s), 0 warning(s)
Downloading files
Downloading file c:\work\...\registry_viewer\x86dbg\pspcmonkey.exe.
Provisioning the device...Failed
Error code: 0x80004005 (-2147467259)
Finished downloading.
Could anyone help me. Even some sample code to get the hello world msg displayed on the emulator screen.
Your help will be greatly apreciated.

Cheers. I followed all that and have been doing some playing around with the sample code and other things.
Everytime I go to build the exe and the emulator starts up and I get the msg box saying about the connection and provisioning the device. Then I get the following msg
Downloading files
Downloading file c:\program files\...\target\x86\tickstatsce.exe.
Provisioning the device...Timed out
Finished downloading.
Sorry about the questions, but im just getting started.

Make sure you select the POCKET PC 2003 configuration and not the STANDARDSDK. Also, select the appropriate CPU target and device.

Well now.. I got the following problem. My app does not leak memory, however, the available physical memory (returned by call to GlobalMemoryStatus() )seems to decrease during the lifespan of the application. This is due to memory fragments that are lost(??) caused by the many memory allocations-deallocations in the program.
What my question is now. If I would run the app for a looooong time could that result in a crash of the system?? I mean does the system really lose the unallocated memory fragments inbetween some allocated memory fragments resulting in a possible out-of-memory error while there actually is still a lot of memory available?
If I would have for example unallocated memory of 1kb between two blocks of allocated memory and I want to allocate 1kb will it use that unallocated part or will it allocate the memory behind the last still allocated mem chunk...
If anybody can help me with that...

Davy

Hello,
I am using eVC 4.0 with ARM processor.
The problem is
_bstr_t bstrProvider(TEXT("Microsoft.SQLSERVER.OLEDB.CE.2.0")); throws a Datatype Misalignment exception, even though I'm able to execute the same code on the Pocket PC 2003 emulator.
Any insights ?
Thanks and regards,
Amit

One clarification in this context is required. I am trying to use PXA255 based pocket PC with the SQL Server CE 2.0.
There is only one set of installation files for ARM processors under Sa1100.
The question is, can it a possibilty that the DLLs meant to be used on SA1100 platform don't have data compatibility with PXA255 ? That would explain why it is working in emulator and not with the device.
I have also tested with PXA250 based device and the application runs perfectly fine.
Any advice would be of great help.
Thanks and regards,
Amit

Can the ADOCE and OLE DB Files for ppc 2002 be used for ppc 2003 ?
Everywhere in the installation instructions for SQL Server CE 2.0 it is mentioned to use Microsoft eMbedded Visual Tools 3.0 while I am using eVC 4.0. If I cannot use the same files, where to look for the files to be used with ppc 2003 ?

Hello,
I am using eVC 4.0 and Pocket PC 2003 emulator. I am trying to install SQL Server 2.0 on the emulator as per the online books provided with the installation. The problem is when I try to copy ADOCE and OLE DB Files onto the emulator, it pops up a dialog to confirm overwriting few system files (adocedb30.dll for example). When I select Yes, it says access denied, make sure disk is not write protected and the file is not in use. The only application running on the emulator at this time is file explorer.
Any help is appreciated.
Regards,
Amit

Skip any files the emulator does not allow you to overwrite.
