C++ Syntax

void

MKI_DialogControlSetArea(

HWND f_hWindow,

__int32 f_nTextCtlID,

__int32 f_nUnitCtlID,

const double f_dValue );

Converts an area value (based on the currently active length unit) to a string and writes that string along with the current length unit (squared) to edit or text controls in a dialog window.

Resulting values between -1.0e-100 and 1.0e-100 will always be displayed as 0.0 to avoid funny rounded displays such as -0.0.

Parameters

f_hWindow

[HWND] Handle of the dialog window that contains the controls.

f_nTextCtlID

[__int32] Identification number of the text or edit control to receive the area value. Will be ignored if negative.

f_nUnitCtlID

[__int32] Identification number of the text or edit control to receive the area unit. Will be ignored if negative.

f_dValue

[double] Floating point value to be converted into a string and displayed in the controls. If the value is MKI_DOUBLE_NOVAL, the area value control will be cleared.
