Methods > SetAnimFromMemory method

Remarks

Changes, at run-time, one of the animations associated with a button.

Syntax

Visual Basic

control.SetAnimFromMemory (index as enumPictures, pDataInMemory as string, datasize as long) as boolean

Visual C++

BOOL control.SetAnimFromMemory (short index, VARIANT pDataInMemory, long datasize);

Parameter

Description

index

Numerical value that represents the index of the picture property to change. Supported values are the following:

Mnemonic constant	Value	Meaning
PICTURE_NORMAL	0	Changes the animation associated with the Picture property
PICTURE_PRESSED	1	Changes the animation associated with the PicturePressed property
PICTURE_MOUSEOVER	2	Changes the animation associated with the PictureMouseOver property

pDataInMemory

Variant parameter containing the pointer to AVI or GIF data previously loaded in memory.

datasize

Numerical value that represents the data size in bytes.

Visual Basic example:

Dim bitsavi As String

Dim length As Integer

bitsavi = LoadResData(101, "AVI")

length = LenB(bitsavi)

BtnEnh1.SetAviFromMemory PICTURE_NORMAL, bitsavi, length

With this code the Picture property will be changed using an AVI animation identified by xxx (contained in a .RES file).

Visual C++ example

VARIANT va;

VariantInit (&va);

va.vt = VT_BYREF | VT_UI1;

va.pbVal = (BYTE *) pointer_to_avi_in_memory;

BtnEnh1.SetAviFromMemory (PICTURE_NORMAL, va, size_of_data);

With this code the Picture property will be changed using an AVI animation previously loaded in memory.

Return value

Value	Meaning

FALSE	The operation failed
TRUE	The operation was successful
