Thank you.
One more question:
Are there any issues in serializing a class in Pocket PC and desrializing it in Windows XP and vice-versa, or is this possible at all?

If you mean data binary compatibility with ARM, the answer is yes. You can serialize a structure to a file using WriteFile on the desktop and read it on the Pocket PC with ReadFile.

I'm only scratching the surface here. The application that I'm writing needs to transfer commands (text) and binary data (pictures) to and from Pocket PC. So, I'm trying to decide what is the best way to transfer the binary part.
I'm not sure if using WriteFile would apply in my case, since I need to write to the disk first and read back again.
A sort of in-memory solution would be more elegant, with no performance penalty. (I'm coming from C#, where you can serialize a class in memory and send it down the socket to be read by the other party)
Any ideas?
Your comments are valuable.

What I meant is that data is read and written in the exact same way on the PPC and the Desktop.

Don't change it: send it as it is. The Pocket PC will read it using the same code you use on the desktop. This will happen irrespective of the medium - I've already ported images on database blobs to and from the Pocket PC without any format changes.

Hi All,
I am using HP, TOSHIBA & DELL AXIM PocketPC's.
How to prevent lose of data when I hard-reset my PocketPC device ?
For example, if i lost registry keys and other third party dll's which are necessary to run my application.
In the other word, I need to auto run my application after hard reset the device.
Suggestions or idea are most welcome.
Regards,
AKS

Put your desired cab files into the file store. This is a permanent memory which isn't lossed after a hardreset.
The cab files are automatically reinstalled after a hardreset.

I am using C# and developed a program. When I load it into my PC2003 iPAQ, it says the company is "My Company." How can this be changed to meaningful data?
Thank you

Hello everybody,
What application should I use to debug application directly PocketPc?
thanks
|
|
|
|
|
You can download Microsoft eMbedded Visual C++ either version 3 or 4. They both debug Pocket PC.
Hope that helps, or have I missed the point?
Ant.

Hi,
I'm writting an application in embedded visual c++ 3.0, and I need to
encrypt and decrypt some buffers, using the Rijndael encryption. Does
anybody have any code, components or links related to that?
Thanks!

Hello all!
I'm just starting out with the PPC and was stepping through a super simple sample (ie. create a project and compile it - deploy to emulator and run). Nothing at all exciting or hard.
I'm able to get the simple wizard generated project to compile and run on the emulator. What I'm having a problem with is that when I try to go to the form (the project is a Windows Application), it displays the following error message:
"An error occurred while loading the document. Fix the error, ...
File or assembly name EnvDTE, or one of its dependencies, was not found."
I can't find a reference to it anywhere and when I actually try to add the DLL as a reference (envdte.dll), it doesn't help. Neither can I add it as "envdte" or "Microsoft Development Environment" (or whatever it was called in a article I found to try and solve the problem).
So, what do I need to do so that I can actually add things to the form?
Any help will be appreciated!
Thanks,
Mike

Please state what development environment you are using: VS.Net, eVC3, eVB, eVC4?

Sorry. Forgot to put that. I'm using VS.Net 2003. Do I need to install anything else?
Thanks,

Thanks. I'm sure that would be it since I haven't installed anything for the Pocket PC.
Thanks for the article reference. It's next on my list when I get some spare time.
Thanks again,
Mike

Hi,
How can I remove the default menu on the command bar to the right hand side which is for the keyboard etc. I've tried such things as
CMenu* KBmen = m_wndCommandBar.GetMenuBar(m_wndCommandBar.GetNumButtons()-1);
KBmen->DestroyMenu(); // Detach();
m_wndCommandBar.ResetCommandBar();
But I'm very new to CE (palm top) development am having a few problems.
Thanks,
ar

Try this to remove
HWND hTaskBarWnd = ::FindWindow(_T("HHTaskBar"), NULL);
if (hTaskBarWnd) {
::EnableWindow(hTaskBarWnd, FALSE);
::ShowWindow(hTaskBarWnd, SW_HIDE);
}
and this to show it again
HWND hTaskBarWnd = ::FindWindow(_T("HHTaskBar"), NULL);
if (hTaskBarWnd) {
::EnableWindow(hTaskBarWnd, TRUE);
::ShowWindow(hTaskBarWnd, SW_SHOW);
}

Thanks for the reply,
I tried your code but it had no effect, I tried to add it before and after I made my menu, is their a proper place to put such code, like do I have to wait until the program is fully up and running or is it ok to put into the likes of CMainFrame::CMainFrame() or int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
I cam across
::SHFullScreen(m_hWnd, SHFS_HIDETASKBAR);
which I have also tried, but get the following error
error LNK2019: unresolved external symbol _SHFullScreen referenced in function "protected: __thiscall CMainFrame::CMainFrame(void)" (??0CMainFrame@@IAE@XZ)
How come I cant access m_hWnd ?

ar

The error message is probably because you have missed linking to Aygshell.lib
Ant.

Hi Antony,
Thanks for the reply, I've since added the Aygshell.h and aygshell.lib to the project, but am still getting the same error
--------------------Configuration: MyProj- Win32 (WCE x86em) Debug--------------------
Linking...
MainFrm.obj : error LNK2019: unresolved external symbol _SHFullScreen referenced in function "protected: __thiscall CMainFrame::CMainFrame(void)" (??0CMainFrame@@IAE@XZ)
X86EMDbg/MyProj.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
MyProj.exe - 2 error(s), 0 warning(s)
If you have any other ideas as to why this is happening I'd be very grateful.
Regards,
ar

According to the Help you should include
windows.h
sipapi.h
shlobj.h
prsht.h
even though it is defined in Aygshell.h
However this would not cause the linker to fail. Have you tried cleaning the entire project and rebuilding?

The above was posted by me. Sorry wasn't logged in!
Ant.

Thanks Antony,
I tried what you suggested and a few other things but still no luck, which I think seems to be strange.
Would it have anything to do with the fact that the project was started by selecting 'WCE Pocket PC Application' as when I tested the code on a new project I started 'WCE Pocket PC Application (exe)' it worked, worked as in compiled and ran on the emulator, not tested on the device, but in the current project I cant even get it to compile.
Thanks again,
ar

Um, I have to say I am not sure what the difference would be here, Sorry.
Have you compared the projects? I'm sure you will glean a lot from the comparison.
Ant.
