1.好像没有其它方法，为什么不用__FILE__ 中取?
2.fopen，您可以加上全路径。
3.wince2.11没有用过，但我想是支持的。在CE帮助中，一般均说明此函数从那个版本开始支持，但fopen中却没有。
4.下面是CE帮助中的一段：
CWinApp::WriteProfileString
This method writes the specified string into the specified section of the .ini file in the application.
BOOL WriteProfileString(
LPCTSTR lpszSection,
LPCTSTR lpszEntry,
LPCTSTR lpszValue );
5.不知您所用的CE版本为多少。CE3.0不支持中文，如果您所用的是3.0，那一定是OEM商汉化了CE。可能只支持一种字体;最新版.Net支持中文，有多种字体供选择。
PC与掌上电脑的串口是不是一样，这很难说。因为嵌入式开发是针对不同硬件平台进行的!
有的掌上电脑用的是标准的RS232，有的不是。
您用EVT(EVC和EVB)写的串口操作程序，可以下载到开发板上进行测试。当然开发板上需有串口硬件。

Release configurations use the following macros:
RETAILMSG(cond, printf_exp). Conditionally displays the print message.
RETAILLED(cond, parms). Conditionally outputs WORD values to the LED.
ERRORMSG(cond, printf_exp). Prints "Error: File Line" before the print message.
To enable the debug macros, you must build a debug configuration. Debug configurations use the three retail macros listed above, as well as the following debug macros:
DEBUGMSG(cond, printf_exp). Conditionally displays the print message.
DEBUGLED(cond, parms). Conditionally outputs WORD values to the LED.
DEBUGCHK(expr). Asserts the expression. If expr is FALSE, the macro calls DEBUGBREAK.
DEBUGZONE(zone_id). Tests the mask bit in the current debug zone settings. You can use DEBUGZONE to turn debug zones on or off.

网上down到的，有关unicode的函数集：
Attribute VB_Name = "modUniCode"
Option Explicit
Public Function MemStringToLong(StringIn As String) As Long
On Error Resume Next
Dim hWorkVal As String
" Convert the String back to Long Integer.
" Converting back to Big Endian format.
Dim i As Long
For i = 4 To 1 Step -1
hWorkVal = hWorkVal & Hex(AscB(MidB(StringIn, i, 1)))
Next i
" Return Long Integer value.
MemStringToLong = CLng("&H" & hWorkVal)
End Function
Public Function LongToMemoryString(ByVal lInputValue As Long) As String
Dim hWorkVal As String
Dim n As Long
Dim i As Long
" Convert to HEX value.
hWorkVal = Hex(lInputValue)
" Check to see if it is not zero.
If hWorkVal <> "0" Then
" Convert to memory storage format (Little Endian).
" For example, 0000A411 would convert to 11A40000.
"
" Place leading zeros in 8 character sequence to
" maintain consistent character count
n = Len(hWorkVal)
If n < 8 Then
hWorkVal = String(8 - n, "0") & hWorkVal
End If
"
" Use ChrB to rebuild Bytes.
For i = 7 To 1 Step -2

在EVC3.0下怎样使编出来的窗口最大化(占满所有屏幕)，并能够将开始菜单条挡住?
BOOL SHFullScreen(
HWND hwndRequester,
DWORD dwState);
注意包含Aygshell.h
用shfullscreen产生全屏窗口，用showwindow隐藏任务条，用movewindow设置窗口大小为全屏。
代码如下：
#define MENU_HEIGHT 26
RECT rc;
//get window size
GetWindowRect(hWnd, &rc);
SHFullScreen(hWnd, SHFS_HIDETASKBAR | SHFS_HIDESIPBUTTON);
ShowWindow(hwndCB, SW_HIDE);
MoveWindow(hWnd,
rc.left,
rc.top-MENU_HEIGHT,
rc.right,
rc.bottom+MENU_HEIGHT,
TRUE);
Windows CE 3.0 supports the standard Winsock 1.1 functions.except the asychronous functions.
