DialogBoxIndirect info  Overview  Group

The DialogBoxIndirect macro creates a modal dialog box from a dialog box template in memory. DialogBoxIndirect does not return control until the specified callback function terminates the modal dialog box by calling the EndDialog function. The DialogBoxIndirect macro uses the DialogBoxIndirectParam function.

int DialogBoxIndirect(

    HINSTANCE hInstance,

// handle to application instance

    LPDLGTEMPLATE lpTemplate,

// identifies dialog box template

    HWND hWndParent,

// handle to owner window

    DLGPROC lpDialogFunc 

// pointer to dialog box procedure



Identifies the instance of the module that creates the dialog box.
Pointer to a global memory object containing a template that DialogBoxIndirect uses to create the dialog box. A dialog box template consists of a header that describes the dialog box, followed by one or more additional blocks of data that describe each of the controls in the dialog box. The template can use either the standard format or the extended format.

In a standard template for a dialog box, the header is a DLGTEMPLATE structure followed by additional variable-length arrays. The data for each control consists of a DLGITEMTEMPLATE structure followed by additional variable-length arrays.

In an extended template for a dialog box, the header uses the DLGTEMPLATEEX format and the control definitions use the DLGITEMTEMPLATEEX format.

Identifies the window that owns the dialog box.
Pointer to the dialog box procedure. For more information about the dialog box procedure, see DialogProc.

Return Values

If the function succeeds, the return value is the nResult parameter specified in the call to the EndDialog function that was used to terminate the dialog box.

If the function fails, the return value is -1. To get extended error information, call GetLastError.


The DialogBoxIndirect macro uses the CreateWindowEx function to create the dialog box. DialogBoxIndirect then sends a WM_INITDIALOG message to the dialog box procedure. If the template specifies the DS_SETFONT style, the function also sends a WM_SETFONT message to the dialog box procedure. The function displays the dialog box (regardless of whether the template specifies the WS_VISIBLE style), disables the owner window, and starts its own message loop to retrieve and dispatch messages for the dialog box.

When the dialog box procedure calls the EndDialog function, DialogBoxIndirect destroys the dialog box, ends the message loop, enables the owner window (if previously enabled), and returns the nResult parameter specified by the dialog box procedure when it called EndDialog.

In a standard dialog box template, the DLGTEMPLATE structure and each of the DLGITEMTEMPLATE structures must be aligned on DWORD boundaries. The creation data array that follows a DLGITEMTEMPLATE structure must also be aligned on a DWORD boundary. All of the other variable-length arrays in the template must must be aligned on WORD boundaries.

In an extended dialog box template, the DLGTEMPLATEEX header and each of the DLGITEMTEMPLATEEX control definitions must be aligned on DWORD boundaries. The creation data array, if any, that follows a DLGITEMTEMPLATEEX structure must also be aligned on a DWORD boundary. All of the other variable-length arrays in the template must be aligned on WORD boundaries.

All character strings in the dialog box template, such as titles for the dialog box and buttons, must be Unicode strings. To create code that works on both Windows NT and Windows 95, use the MultiByteToWideChar function to generate these Unicode strings.

Windows 95: The system can support a maximum of 16,364 window handles.
