Halo everyone, i am new to this forum and new to vc++ as well. Nice to meet u all.

as my topic mention above, i am failed to call a function.

by using vc++ 6, i create button on GUI and edited code on it. The function is named as shown below.In this part of code, i would like to call another function that called mask and there are 3 variables (m,x,and y)that i wish to bring along to the mask function.

The problem i meet is i failed to call the mask function.
what happen to my code?? is that i should not use "void" ??

Pleas advise ...thanks !!

void CFingerPrintBiometricSystemDlg::OnThinning()
IplImage* temp=cvCreateImage(cvSize(640,480),IPL_DEPTH_8U,1) ;
temp = cvLoadImage( "threshold_thin.bmp", 0 );
if(!temp) printf("Could not load image file:%s\n","threshold_thin.bmp");

int m;
int x=2;
int y=2;

CvScalar s;
for (m=0; m<8 ; m++)
{
    for (x; x< temp->width; x++)
    {
        for (y; y<temp-> height;y++)
        {
            s= cvGet2D(temp,y,x);

            if (s.val[0]=0)
            {
            mask(m,x,y);
            }
        }
    }
}
