Actually memBM =3D c_func(iCreateCompatibleBitmap,{hdc, 197, 275}) isnt =
even needed.
Original Message:
To display a DIB (device independant bitmap) in Windows (95,98,2K,NT)
If I use the below Code (My_Code) what if any compatibility issue =
might I run into?
From Microsoft SDK
HDC memDC =3D CreateCompatibleDC ( hDC );
HBITMAP memBM =3D CreateCompatibleBitmap ( hDC );
SelectObject ( memDC, memBM );
=20
This Works in my program on my Machine.
My_Code:
constant SRCCOPY =3D #CC0020
atom memDC, memBM, hBitmap, Bitmap_file, selBmp, ShowBmp
Bitmap_file =3D allocate_string("eumans.bmp")
memDC =3D c_func(iCreateCompatibleDC, { hdc })
memBM =3D c_func(iCreateCompatibleBitmap,{hdc, 197, 275})
hBitmap =3D c_func(iLoadImage,=20
{NULL, Bitmap_file, IMAGE_BITMAP, 197, 275, =
LR_LOADFROMFILE})
selBmp =3D c_func(iSelectObject,{memDC, hBitmap})
ShowBmp =3D c_func(iBitBlt, {hdc,=20
415, -- x placement
220, -- y placement
197, -- already know =
width
275, -- already know =
height
memDC,
0,=20
0,
SRCCOPY} )
Thanks in advance
