just do "if (Mode & MODE1)" without the " == MODE1" part. So the first if statement would look like this:

if (Mode & MODE1)
{cout << "Mode 1 ";}

and you would modify the rest of them accordingly.

Turt99, I use a char, because I only need 8 modes, but there''s nothing like ''byte'' that MSVC++ used exept an unsigned char.

If I want to use mode 1 and 3 this is how I would enable them:

0: Mode = 0;1: Mode = (Mode | MODE1);2: Mode = (Mode | MODE3)this is what should happen with Mode''s bits:0: 000000001: 000000012: 00000101that''s a 5, right?Then what this program should do:      if (Mode&MODE1 = MODE1) bits: if (00000101 & 00000001 = 00000001)      if (Mode&MODE2 = MODE2)bits: if (00000101 & 00000010 = 00000010)      if (Mode&MODE3 = MODE3)bits: if (00000101 & 00000100 = 00000100)      if (Mode&MODE4 = MODE4)bits: if (00000101 & 00001000 = 00001000)etc.so that is true, false, true, falseAnd it should write: "Mode1 Mode2 Mode3 Mode4 " 

Ofcourse it''s a stupid example, but it''s a lot clearer than posting my program...

Thanx, Marty

Thanx, Jallen... It works!

I think the level of the questions gets very very low lately. This is more like read a C book.
This question has nothing to do with OpenGL anyway.

Is this newsgroup moderated by someone?

Ahhh, I see, Makes sence to me now, and with out the equals in the if statement I can see how it works, if none of the bits match then it would return 00000000 which is 0 or false

Interesting

Your if statement
>if (Mode & MODE1 == MODE1)

Does not function like you would expect. The == operator takes priority over the & operator. So your == condition will be checked first and it''ll return true. Now your variable Mode is checked for != 0 and that returns true as well.

Your if statement should read as follows:
if ((Mode & MODE1) == MODE1)

And because you only work with flags you can remove the == MODE1, resulting in:

if (Mode & MODE1)

This should work.

Here''s an idea. When you''re in your development environment, hit F1. This will bring up something called help. READ IT. Now, buy a book on C++. READ IT. Then, when you get an error message like ''missing ; after )'', you''ll be informed enough to find a ) that is missing the ;

Have a nice day!

Sorry, didn''t mean to post my complaint about the level of the questions here anonymously.

My question is: is this forum moderated in any way to avoid most of these trivial questions?
