WinCreateDlg

This function creates a dialog window.

Syntax

WinCreateDlg(hwndParent, hwndOwner, pfnDlgProc, pdlgt, pCreateParams)

Parameters

hwndParent (HWND) - input

Parent-window handle of the created dialog window.

HWND_DESKTOP - The desktop window

HWND_OBJECT - Object window

Other - Specified window.

hwndOwner (HWND) - input

Requested owner-window handle of the created dialog window.

The actual owner window is calculated using the algorithm specified in the description of the WinLoadDlg function.

pfnDlgProc (PFNWP) - input

Dialog procedure for the created dialog window.

pdlgt (PDLGTEMPLATE) - input

Dialog template.

pCreateParams (PVOID) - input

Pointer to application-defined data area.

This is passed to the dialog procedure in the WM_INITDLG message.

This parameter MUST be a pointer rather than a long.

Returns

hwndDlg (HWND) - returns

Dialog-window handle.

NULLHANDLE - Dialog window not created

Other - Dialog-window handle.

Remarks

This function is identical to the WinLoadDlg call except that it creates a dialog window from pdlgt in memory, rather than a dialog template in a resource file.

This function should not be used while the pointing device capture is set (see WinSetCapture).

Example Code

This example loads a dialog template from the application's resources and uses the template with the WinCreateDlg function to create a dialog window. This example is identical to calling the WinLoadDlg function, but gives the application the advantage of reviewing and modifying the dialog template before creating the dialog window.

#define INCL_WINDIALOGS         /* Window Dialog Mgr Functions  */
#define INCL_DOSRESOURCES       /* OS/2 Resource functions      */
#include <os2.h>

PFNWP    MyDlgProc;
#define  ID_DIALOG  1

PDLGTEMPLATE pdlgt;     /* dialog template       */

DosGetResource(0L, RT_DIALOG, ID_DIALOG, (PVOID)pdlgt);

/* make any changes to dialog template here */

WinCreateDlg(HWND_DESKTOP,
    NULLHANDLE,  /* owner window                */
    MyDlgProc,   /* address of dialog procedure */
    pdlgt,       /* address of dialog structure */
    NULL);       /* application-specific data   */
