Body
I am writing a program in which I use an if statement to check some condition; if true I increment a counter. The problem is that as soon as the statement is true the variable either gets incremented endlessly or by random number. I have been trying to use some clause to break out of this statement if condition meet but with no luck my code: <pre><code>if(res_vect_angle >=60 && res_vect_angle <=100 && left_mag_b >100) { //line(drawing, *iter_s, *(iter_s -1), Scalar( 255, 255, 255 ), 2,8 ); left_hook_count++; cout<<"Left Hook:..........................!!! "<<left_hook_count<<endl; if(left_hook_count++ == true) { break; } } </code></pre> The whole chunk of code associated with the issue: <pre><code>float M1, M2; float A1, A2; double left_mag_a, left_mag_b; double res_vect_angle; int i = 0; for(vector<Point>::iterator iter_lh = Leftarm.begin(); iter_lh != Leftarm.end(); ++iter_lh) { if(iter_lh->y <=240 && iter_lh->y >=60 && iter_lh->x >=340 && iter_lh->x <=680) { left_detect.push_back(*iter_lh); if(i % 4 == 0) { if(left_detect.size()>4) { for(vector<Point>::iterator iter_s = left_detect.begin()+3; iter_s != left_detect.end(); ++iter_s, i++) { //Resultant Magnetude M1 = pow((double) iter_s->x + (iter_s -2)->x,2); M2 = pow((double) iter_s->y + (iter_s -2)->y,2); left_mag_a = (M1 + M2); left_mag_b = sqrt(left_mag_a); //Resultant Angle A1 = abs(iter_s->x - (iter_s -2)->x); A2 = abs(iter_s->y - (iter_s -2)->y); res_vect_angle = abs(atan2(A1,A2) * 180 /PI); //cout<<"LEFT HOOK ANGLE IS: "<<res_vect_angle<<endl; if(res_vect_angle >=60 && res_vect_angle <=100 && left_mag_b >100) { //line(drawing, *iter_s, *(iter_s -1), Scalar( 255, 255, 255 ), 2,8 ); left_hook_count++; cout<<"Left Hook:..........................!!! "<<left_hook_count<<endl; if(left_hook_count++ == true) { break; } } } } } } } </code></pre> Hope this helps guys ps. <code>left_hook_count++;</code> is a int variable declared on top of my main().

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
