What is handle??????

[ctyuang]

Im trying to put a bitmap onto my button. However, one of the function I use needs a parameter that is "handle" type, which is the bitmap's handle.

Now, my question is, what is the handle of the bitmap. I have a bitmap file named "flower.bmp", its ID is IDB_FLOWER, but what is its handle??????

Construct CBitmapButton class. Then Call Create function and then call LoadBitmap() function to put bitmap on a button. See CBitmapButton overview to check out how to put a bitmap on a button. Its self explanatory.

First you have to create an CBitmap object, then load the bitmap source to this CBitmap and then load this CBitmap to your CButton. Like this

CBitmap m_CBitmap;

m_CBitmap.LoadBitmap(IDB_FLOWER);
YourButtonControl.SetBitmap(HANDLE(m_CBitmap));

Sorry, it should be HBITMAP not HANDLE.

YourButtonControl.SetBitmap(HBITMAP(m_CBitmap));

[ric]

operator HBITMAP( ) const;

Return Value

If successful, a handle to the Windows GDI object represented by the CBitmap object; otherwise NULL.

Remarks

Use this operator to get the attached Windows GDI handle of the CBitmap object. This operator is a casting operator, which supports direct use of an HBITMAP object.

Use like this:

HBITMAP handle;
handle = (HBITMAP)my_bitmap;

or just (HBITMAP)my_bitmap;
