C2227: left of '->width' must point to class/struct/union/geberic type

Kasirga (7)
.....
...
unsigned int unResAvail;
unsigned char unsSpeedValue;
unResAvail= clasModule ->getAvilableResults();

if(unResAvail > 0)
{

int width = unResAvail->width;
int height = unResAvail->height;
int bpp = unResAvail->bytesPerPixel;
..
..
...

how can i fix this error!!!! Thanks

It depends on how you've declared unResAvail or clasModule.

If they are classes, replace the -> with .
If they are ints, you need to define them as classes with the appropriate types.

My whone program. was can i do ?

...did you write all this code yourself? What is the purpose of all this? It seems like you may be reaching a bit beyond your grasp.

Also, please enclose all code in code tags - makes it much easier to read.
