cs423-cotter6 Windows Programming Environment - MS Dev Studio

Visual Studio.NET

cs423-cotter8 Windows Programming Start New Project Microsoft Visual Studio.Net Start -- Programs -- MS Visual Studio -- MS Visual Studio To create a new project: –From Start Page: Create -- Project –Identify storage location for new project –Provide Project name –OK

New Project Window

cs423-cotter11 Windows Programming Add / Create files Project – Add Existing Item – C++ File Locate desired files. Repeat for all needed files For new files: Project -- Add New Item – C++ File Identify file.

cs423-cotter14 Windows Programming Add Libraries Project -- Properties linker tab -- category = Input -- add library names to “Additional Dependencies” for sockets, add “wsock32.lib”

Add Libraries

To support Multi-threaded Programs: Select Project  Program Properties Select C/C++ tab –Code Generation subtab Runtime Library item: –Default is “Single-threaded Debug (/MLd)” –Select “Multi-threaded Debug DLL (/MDd)”

cs423-cotter20 Windows Programming Select Active Configuration Two compile configurations available –Release –Debug Build – select “Configuration Manager” Select either Debug or Release –Note that debug versions create large (megabyte) files.

Active / Debug Configuration

cs423-cotter23 Windows Programming Build and Execute Project Build -- Build “project_name” Check message window for compile and link status. If no errors are indicated, execute program. Debug – “Start Debugging” or “Start Without Debugging”

cs423-cotter26 Windows Threads Similar in concept to processes, but designed to identify multiple activities that can be scheduled independently. All programs have at least 1 thread -- main ( ) program Any thread can create new threads.

cs423-cotter27 Windows Threads In C language (console mode): unsigned long _beginthread ( void(_cdecl *start_address)(void *), unsigned stack_size, void *arglistv ); Required Header: Required Libraries: LIBCMT.LIB or MSVCRT.LIB

cs423-cotter28 _beginthread ( ) void(_cdecl *start_address)(void *), –Start address of the routine that will begin the thread –The routine must have no return value unsigned stack_size, –Provide either a stack size for new thread or, if value is 0, use the same stack size as “parent thread” uses. void *arglist –Address of data item passed to new thread or NULL if nothing passed
