A collection of classes for CE that do not use ATL or MFC, plus an FTP client, database viewer, and sample application that solves beam deflection equations.

Introduction

CeLib is a collection of classes that are a cross between ATL and MFC Window classes with some additional functionality thrown in to get some of the functionality you get from MFC (string, network and UI).

I first started programming for Windows CE version 2.0 for HPC and 2.01 for Palm-sized PC. The only tools, available were a Visual Studio 5.0 plugin for C++ and a Visual Basic plugin for 5.0. MFC was avialble for the 2.0 HPC platform, but not for 2.01 Palm-sized PC, in addition it was a 300+ K additional installation and wasn't yet included on most ROMs. I needed to write applications that would run on both so MFC and ATL were out. So I looked at the source for MFC and ATL and some other window class library and stole the ideas and wrote my own.

An application with significant functionality can be created in 20k. The database browser that is included is about 50k and requires no DLLs that aren't already installed.

Version Information

These libraries will build for operating system versions 2.0, 2.01 and 2.11. They have been tested and work on HPC 2.0, Palm-sized PC 1.0, Palm-sized PC 1.2, HPC Pro 3.0, and PocketPC in compatibilty mode.

Some important files

CePlatform.h Compile time defines to make life easier for version differences in library includes all libraries required for COM and normal Window functionality. Library names are different across different version of CE as well as between the emulator and non-emulator versions, this header hides those differences.

Also note that in Windows CE, many library functions from Windows 95/NT like WINSOCK and TAPI are included in the standard libraries, NOT in a special libraries.

CeDebug.h Debug support such as TRACE, ASSERT
CeMisc.h Miscellaneous helper classes

GeneralCeFtpClient question (CeSocket, actually) Pin
Scott Leonard at 25-Jun-01 6:55

First off, great job on the library.

I have two questions. I am trying to implement a file distribution component for a large number of handhelds (currently using Symbol PPT2700's). This is basically an ftp client I have based on the CeFtpClient class. I am not familiar with the FTP protocol, and I haven't bothered checking the RFC, but I noticed that if I just connect to a server and request a file without requesting a directory listing first, it just times out and I get a zero byte file on the device. It's not a big deal, just a curiosity.

My other question is a problem. If I have two clients connected w/downloads in progress, and a third connects, it cannot download anything. It times out on the switch(select(...)) statement on line 228 of CeSocket.cpp. Any ideas? I have tried passive and non passive and neither works. If I connect with another PC using the command line MS FTP client as the third connection, it works fine. The server is a Win2k Pro box on a test network w/max anon users at the default of 10.

Any help would be greatly appreciated,
Scott Leonard
