Copy Files From your PC to PocketPC

Environment: [eg 98, Me, W2K, XP]

Have you ever wanted to copy a file from your Desktop Computer to your handheld Pocket PC?

This included any Windows CE version too?

Well if so, I will present an easy way to do it here: It's called the Remote Application Programming Interface, or, RAPI in this article. It is touched on in the MSDN but not really explained very well.

RAPI encapsulates the old file function functionality:

Old C function RAPI Function
CreateFile() CeCreateFile()
WriteFile() CeWriteFile()
ReadFile() CeReadFile()
etc... etc...


Ok, you get the idea...

So how do I call these RAPI functions?

There are two ways I know of. These functions are defined in the Microsoft include file: rapi.h. You simply include this in your project along with linking in rapi.lib and your business. However, since these two files are not very common and will crash a machine that doesn't have the correct .dll's. By the way, tehse are installed with ActiveSync. Since this is a bit frustrating, we can do it the hard way. We can manually load the exported functions from the .dll itself. This is done for you in the Initialization function of my Wrapper class.

How do I use this in my application?

1. Alright, download the source files: RencherRAPI.cpp and RencherRAPI.h
2. Include them in your project.
3. Include RencherRAPI.h in the .h file of where you would like to connect to the Pocket PC.
4. In the public section of the class declaration, create a member variable of type CRencherRAPI.
5. Someplace in your OnInitialUpdate() or InitDialog() functions or someplace else call the InitializeSettings() member variable [by the way this can be seen in RencherRAPI.cpp].
6. If it succeeds, that means RAPI is alive and well and you have a Pocket PC or Windows CE device connected!
7. To transfer a file from the PC to the Pocket PC, call the CopyFiletoWinCE() function.

There is tons of other functionality in RAPI. This article is designed to show you how to call this interface, you can figure out how to utilize the other RAPI calls defined in the MSDN and elsewhere. Best of luck.

  • Writing actual size

    Thank you for the source code. I've just made som minor changes. Etc. I added the iBytesRead instead of always writing with BUFFER_SIZE. Also I added the call to CeSetEndOfFile, in case of re-writing a smaller file to the Pocket PC. int iBytesRead = 0; while((iBytesRead = oldFile.Read(&cTemp, BUFFER_SIZE)) > 0){ CeWriteFile(h, &cTemp, (DWORD)iBytesRed, &nbytes, NULL); } CeSetEndOfFile(h);

  • Modifying Sample Code

    Posted by Legacy on 10/07/2003 12:00am

    I've taken your great sample code and I'm trying to modify it so that it creates a database in the object store instead of creating a file. But I'm having all sorts of troubles with headers. I'm sort of a newbie at this, as I'm sure you'll be able to tell :-) I created a new .cpp file, and this line of code:

    CEOID oid;

    produces an error that CEOID is an undeclared identifier. What header file do I need to add so that this will work? I tried adding this path:

    C:\Program Files\Windows CE Tools\wce420\POCKET PC 2003\Include\Emulator

    under "Project Settings/C++/Preprocessor/Additional include directories"

    When I do that, the error about CEOID (and a lot of others) goes away, but now I get several errors including:

    stdlib.h: '_JBLEN' : undeclared identifier
    winnt.h: 'PCONTEXT' : missing storage-class or type specifiers
    winnt.h: 'ContextRecord' : missing storage-class or type specifiers

    I know this is just a matter of knowing what headers are needed. What .h files do I need to include at the top of my new .cpp file? Thanks a lot!

    Any help, thanks,

  • What abt Pocket PC to Desktop via Wireless

    Posted by Legacy on 09/06/2003 12:00am

    Hi all,
    I am using a 802.11b wireless LAN to connect to PC. Doing this establishes a LAN IP for the handheld. I need to copy some files to the PC and then from the PC to the handheld device. From desktop to PC is no problem I can use the CopyFile() API and give the path as "\\Machine Name\Folder\DestFileName" - it works - without ActiveSync!
    But from the PC to the handheld, I have problem as I don't have a machine name for the handheld. So I have depend on CeWriteFile RAPI file - for which I have to depend on the ActiveSync :-(
    I want to give up ActiveSync because if the Wireless LAN fails, the ActiveSync disconnects and doesn't connect automatically.
    So I was wondering if there is any way of either starting the ActiveSync from the Handheld device programmatically. Or otherwise if there is any way of copying the files from PC to the handheld which doesn't depend on ActiveSync.
    Thanks in advance and best regards,
    Guru

    Thanks, and thanks for the code, very helpful,
