Agenda Part 2 / 3

• Highlights of eVC 4.0
• Tool Tips
• IDE Keyboard Shortcuts
• Preprocessor
• Compiler
• Linker
• TroubleShooting

11
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)

12
PreprocessorPrecompiled Headers

• Key Benefit - Faster Build time
• Obstacles
• Understanding Setup
• Automatic versus Manual
• Establishing Default Settings

13
Precompiled HeadersThree Modes

• Settings For All Configurations

Off
Auto
Manual
14
Precompiled HeadersThe Meaning of Through
header
Use Precompiled Headers Up to and including
stdafx.h
include "stdafx.h" include "propsip.h" include
ltcommctrl.hgt include ltaygshell.hgt include
ltsipapi.hgt
15
Precompiled HeadersSetup for Manual Mode (1 of 2)
Select Source File
Create headers for one source file
16
Precompiled HeadersSetup for Manual Mode (2 of 2)
Select Source File
Use headers for all other source files
17
Precompiled HeadersDefault Settings
Select Project
Sets default for new items added to project

• MyLen(char p)
• return 4
• Resulting Exported Function
• ?MyLen_at__at_YAHPAD_at_Z

22
CompilerBuilding 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
