You need to read a book on MFC (if you are any good at Windows programming, then you could skip other chapters, just read the basics of the framework and jump on to the chapter that talks about dealing with bitmaps and GDI in MFC). After you finish it, you will be all set to go.

hello all
i am using VS 6.0, VC++, Win32
My Task is to display png image on Transparent window.....
i used SetLayeredWindowAttributes to make my window transparent and it works fine......but the problem is my image also gets transparent and nothing is displayed ......
can anybody suggest me how to overcome this problem.....i.e only window should become transparent but not the image.....
Thankx:::

You can use an image with a solid colour applied in the parts that should be transparent. You then display the image using alpha keying, which renders the image except pixels that are this colour.
Here is code that displays an an image with 75% opacity, except for pixels that are RGB(255,0,0) - which are not displayed at all.
SetLayeredWindowAttributes(hwnd, RGB(255,0,0), (75*255)/100, ULW_COLORKEY|LWA_ALPHA);
If you remove the |LWA_ALPHA part, you get full opacity on all pixels except the red ones, which are not shown at all.

Thankx For ur reply
But it gives compilation error as
ULW_COLORKEY undefined
|
|
|
|

Oops, sorry about that - i forget which one it is, you need one of these #defines (I think it's the first one)
#define _WIN32_WINNT 0x0601
#define _WIN32_IE 0x0300
|
|
|
|
|
in both #defines i got the same error as
error C2065: 'ULW_COLORKEY' : undeclared identifier
|
|
|
|
|
I think you need one of these (put that into the PreProcessor settings of your project):
_WIN32_IE=0x0500
WINVER=0x0500

Taken from winuser.h (mingw 3.4.5)
#if (_WIN32_WINNT >= 0x0500)
#define LWA_COLORKEY 0x01
#define LWA_ALPHA 0x02
#define ULW_COLORKEY 0x01
#define ULW_ALPHA 0x02
#define ULW_OPAQUE 0x04
#endif

AfxMessageBox(test_size);
Can anybody please tell me what is the error. i am coding in vc2008

double
double val0 = c*bps;
double val1 = val0*spt;
double val2 = val1*h;
double val3 = val2/(1024*1024);
|
|
|
|
|
the answer depends on val2 ,so debug and see whats tha value coming for val2. use breakpoints.

Double and integer are represented as a different binary format.
You should casting double to integer before passing a parameter.
test_size.Format(_T("%d"),(int) val3);
|
|
|
|
|
You are trying tackling with variable of type double variable. If you really wanna to cast the double into integer use casting as :
test_size.Format(_T("%d"),(int) val3);
or use proper format specifier :
test_size.Format(_T("%f"), val3);
- Malli...!

Yes: you haven't properly read the documentation about format specification fields, see for instance [^].
