TroubleShooting
IDE Keyboard Shortcuts






[F1] - Context Sensitive help
[F4] - [Next] (Error, Search result, etc.)
[F6] - [Next Window]
[F9] - [Set Breakpoint] at cursor
[Tab] - Indent blocks of text
[Ctrl] + [End] – Enable auto scroll for
output windows (build, debug, find)
Preprocessor
Precompiled Headers


Key Benefit - Faster Build time
Obstacles:



Understanding Setup
Automatic versus Manual
Establishing Default Settings
Precompiled Headers
Three Modes
Settings For: All
Configurations
Off
Auto
Manua
l
Precompiled Headers
The Meaning of “Through header”
Use
Precompiled
Headers Up
to and
including
stdafx.h
#include
#include
#include
#include
#include
"stdafx.h"
"propsip.h"
<commctrl.h>
<aygshell.h>
<sipapi.h>
Precompiled Headers
Setup for Manual Mode (1 of 2)
Select Source File
“Create
headers”
for one
source
file
Precompiled Headers
Setup for Manual Mode (2 of 2)
Select Source File
“Use
headers”
for all
other
source
files

Windows CE Conditional Compilation


Targeting a Specific Version



#ifdef UNDER_CE
#if UNDER_CE == 300
#if UNDER_CE >= 211
Emulator-Specific Code

#ifdef _WIN32_WCE_EMULATION
Preprocessor
Symbols (continued)
UNICODE Effects
 Unicode functions
are the default:


MessageBox macro
interpreted as
MessageBoxW
Unicode data
structures are the
default:

LOGFONT macro
interpreted as
LOGFONTW
_UNICODE Effects
 Modifies tchar.h
 TCHAR is WCHAR
 LPTSTR is LPWSTR
 _tcscpy is wcscpy
 _T(“x”) is L”x”
 TEXT(“x”) is L”x”
Compiler
Building DLLs using C++

An Include File:
#include "MyLen.h"

The Source Code (MyLen.cpp):
_declspec(dllexport) int _cdecl
MyLen(char * p)
{
return 4;
}

Resulting Exported Function:

?MyLen@@YAHPAD@Z
Compiler
Building DLLs using C++ (cont)

Solution:
// MyLen.H
#ifdef _cplusplus
extern "C" {
#endif
_declspec(dllexport) int _cdecl MyLen(char * p);
#ifdef _cplusplus
}
#endif

Resulting Exported Function:

MyLen
Compiler
Win32 Message Cracker Macros

What They Are:



Macros to help build window procedures
One macro per Win32 message
Benefits of Using:



Make window procedures shorter
Correctly crack apart wParam & lParam
Correctly cast parameter values
Compiler
Win32 Message Cracker Macros (cont)

BEFORE:
MyWindowProc(…) {
switch (msg) {
case WM_PAINT:
<lots of code>
break;
case WM_MOUSEMOVE:
<lots more code>
break;
default:
DefWindowProc(hwnd, msg, . . .);
}
Compiler
Win32 Message Cracker Macros (cont)

AFTER:
MyWindowProc(…) {
switch (msg) {
HANDLE_MSG(hwnd,WM_PAINT,OnPaint);
HANDLE_MSG(hwnd,WM_MOUSEMOVE,OnMove);
. . . }
void
/*
}
void
{
/*
}
OnPaint(HWND hwnd) {
WM_PAINT handling code */
OnSize(HWND hwnd,UINT state,int cx,int cy)
WM_SIZE handling code */
Compiler

The definitions:


#include <windowsx.h>

For a complimentary copy
Linker
Where is that function hiding?

Example:



Where to find "MailOpen", "MailPut", and
"MailClose"
The Answer: msgstore.lib
How to solve that problem in the general
case:
C> dumpbin –linkermember:2 msgstore.lib>msgstore.dat
C> dumpbin –linkermember:2 msmqrt.lib > msmqrt.dat

Tool Tips
TroubleShooting





Debugging via USB
Debugging via network at home
Debugging via network at work
Emulator set up
Adding Win32 DLLs to managed projects
Debugging via USB/serial

Establish ActiveSync Partnership




Use latest version (3.6)
Select correct CPU (WCE Configuration
Toolbar)
For best performance, hide Watch and
Variables windows
Consider using network debugging…
