DIALOG POST

Description

Place a message in the message queue of the specified dialog.

The message is processed by the dialog at a later time, when it reads the message from the queue.

Syntax

DIALOG POST hwnd, Msg, wParam, lParam

Returns

None

Parameters

Name	Type	Optional	Meaning
hwnd	Number	No	Handle of the dialog you want to send a message to
Msg	Number	No	The message you want to send to the dialog
wParam	Number	No	First parameter. This value is Msg dependant
lParam	Number	No	Second parameter. This value is Msg dependant

Remarks

DIALOG POST is different to the DIALOG SEND, which forces the dialog/control to process the message immediately before returning.

DIALOG POST is an asynchronous operation.

By default, thinBasic passes these parameters BYVAL.

If the target dialog is expected to return or alter the values passed in the wParam and lParam parameters, pass them using VARPTR or the return values will be discarded.

For example:

DIALOG POST CBHNDL, %WM_USER + 999, VARPTR(Param1&), VARPTR(Param2&)
