Get the RGB code

Hello,
How could I get the equivalent in RGB of the COLORREF 4276545?

As far as I remember, a COLORREF is just like an RGB value but ordered the other way.

So, assuming that in a 4-byte (32-bit) integer they are packed like this:

RGB packed as - RGBx
COLORREF packed as - BGRx

Then all you have to do is switch the red and blue components.

Code:

---

RGB rgbval = 0;
COLORREF colorref = 4276545;

rgbval = ((colorref & 0xFF) >> 16) & (colorref & 0xFF00) & ((colorref & 0xFF0000) << 16) & (colorref & 0xFF000000);

---

If I remembered the format right (no guarantees), that should convert the COLORREF to an RGB.

Use GetGValue, GetRValue and GetBValue on COLORREF values to extract the colors.

Thank you for the help.

Just curious, aren't these vb specific functions, because I don't see them in the API viewer?

they need to be VB functions because in C they are macros (so you can't get them via declare)

But since I've never programmed in VB you can be sure that everything I say is either completly wrong or it works for C :)

Er, how did you end up at a VB site then? :rolleyes:

Like many others here - searching for a way to use C dlls in VB (I coded the dll and felt responsible for making it available to the VB programmer I worked with)
