Afxwininit (hinstance, hprevinstance, lpcmdline, ncmdshow)

View the afxwininit source code:

Bool afxapi afxwininit (_ in _ hinstance, _ in _ hinstance hprevinstance,

_ In_z _ lptstr lpcmdline, _ in _ int ncmdshow)

{

Assert (hprevinstance = NULL );

// Handle critical errors and avoid windows message boxes

Seterrormode (0) |

Sem_failcriticalerrors | sem_noopenfileerrorbox );

// Set resource handles

Afx_module_state * pmodulestate = afxgetmodulestate ();

Pmodulestate-> m_hcurrentinstancehandle = hinstance;

Pmodulestate-> m_hcurrentresourcehandle = hinstance;

Pmodulestate-> createactivationcontext ();

// Fill in the initial state for the Application

Cwinapp * PAPP = afxgetapp ();

If (PAPP! = NULL)

{

// Windows specific initialization (not done if no cwinapp)

PAPP-> m_hinstance = hinstance;

Hprevinstance; // obsolete.

PAPP-> m_lpcmdline = lpcmdline;

PAPP-> m_ncmdshow = ncmdshow;

PAPP-> setcurrenthandles ();

}

// Initialize thread specific data (for main thread)

If (! Afxcontextisdll)

Afxinitthread ();

// Initialize cwnd: m_pfnnotifywinevent

Hmodule =: getmodulehandle (_ T ("user32.dll "));

If (hmodule! = NULL)

{

Cwnd: m_pfnnotifywinevent = (cwnd: pfnnotifywinevent): getprocaddress (hmodule, "notifywinevent ");

}

Return true;

}

Conclusion: afxwininit completes theapp and some thread initialization operations.
