Uh, there are two problems: syntax AND method.

You have to dereference the pointers in order to store data values, but first the pointers have to point somewhere!

So you might want to add:

ws1R = (float *)malloc( sizeof(float)*3 );
ws1G = ws1R+sizeof(float);
ws1B = ws1G+sizeof(float);

and, for example:

*ws1R = [timerValue intValue];

ws1R = [timerValue intValue]; // this converts the string into an
integer// I tried it without this as well
ws1G = [[dictws1 objectForKey: @"G"]retain];
ws1G = [timerValue intValue]; // this converts the string into an
integer// I tried it without this as well
ws1B = [[dictws1 objectForKey: @"B"]retain];
ws1B = [timerValue intValue]; // this converts the string into an
integer// I tried it without this as well

NSColor *col = [NSColor colorWithCalibratedRed:(float)ws1R
green:(float)ws1G blue:(float)ws1B alpha:1.0];

I get this error when I build:
MyProgram.m:111: error: pointer value used where a floating point value
was expected

Is there a way to convery a pointer value to a floating point value.

I may be totally off on my thinking, but I hope you can do what I am
doing above.

Any suggestions on how to fix this?

Thanks,

We've heard that a million monkeys at a million keyboards could produce the Complete Works of Shakespeare; now, thanks to the Internet, we know this is not true.
