c++ - Unhandled Exception while using cvCreateSeq -

i using cvcreateseq function create sequence in opencv,while debugging exception occurs 'unhandled exception @ 0x7c812afb'.i coding in c , ide visual c++ 2010 express edition.

can tell me why exception ocurring.

thanks,

the code is:-

void main() { char * file = "d:\\testimage.jpg"; temp(file); } void computecococlust(char * filepath) { cvmemstorage * storagecontour = null; cvseq * first_contour = null; iplimage * ioriginal = null; /*load image*/ ioriginal = cvloadimage(filepath,cv_load_image_unchanged); /*load grayscale image*/ iplimage * igray = cvloadimage(filepath,cv_load_image_grayscale); /*show original image in window named 'original image'*/ fnshowimageinwindow("original image",ioriginal); /*show graylevel image in window named 'graylevel image'*/ fnshowimageinwindow("graylevel image",igray); fnreleasingmemoryofwindow("graylevel image",igray); /*------getting single channel image reddish greenish bluish rgb ioriginal----------*/ iplimage *ired = cvcreateimage(cvgetsize(ioriginal), ioriginal->depth, 1); iplimage *igreen = cvcreateimage(cvgetsize(ioriginal), ioriginal->depth, 1); iplimage *iblue = cvcreateimage(cvgetsize(ioriginal), ioriginal->depth, 1); cvsplit(ioriginal, iblue, igreen, ired, null); /*show ired,igreen,iblue in window*/ fnshowimageinwindow("red component image",ired); fnshowimageinwindow("green component image",igreen); fnshowimageinwindow("blue component image",iblue); /*---------------------------------------------------------------------------------*/ /*--------perform canny border detection--------------------------------------------*/ /*for reddish component*/ iplimage * ered = cvcreateimage(cvgetsize(ired),ired->depth,1); cvcanny(ired,ered,10,100,3); /*for greenish component*/ iplimage * egreen = cvcreateimage(cvgetsize(igreen),igreen->depth,1); cvcanny(igreen,egreen,10,100,3); /*for bluish component*/ iplimage * eblue = cvcreateimage(cvgetsize(iblue),iblue->depth,1); cvcanny(iblue,eblue,10,100,3); /*-----show ered,egreen,eblue in window------------------------------------------*/ fnshowimageinwindow("red component border image",ered); fnshowimageinwindow("green component border image",egreen); fnshowimageinwindow("blue component border image",eblue); /*-------------------------------------------------------------------------------*/ /*-----performing union of border images using cvmax-----------------------------*/ iplimage * imaxtmp = cvcreateimage(cvgetsize(ioriginal),ioriginal->depth,1); iplimage * iunionimage = cvcreateimage(cvgetsize(ioriginal),ioriginal->depth,1); cvmax(ered,egreen,imaxtmp); cvmax(imaxtmp,eblue,iunionimage); fnshowimageinwindow("union of images",iunionimage); /*-------------------------------------------------------------------------------*/ /*----getting boundary pixel of each connected component---------------------*/ storagecontour = cvcreatememstorage(0); int numcountour = cvfindcontours(iunionimage,storagecontour,&first_contour,sizeof(cvcontour),cv_retr_ccomp,cv_chain_approx_none); printf("total countours detected %d",numcountour); cvmemstorage * storage = cvcreatememstorage(0); /*-------------------------------------------------------------------------------*/ /*----smoothing contour------------------------------------------------------*/ for(cvseq * seqsmooth = first_contour;seqsmooth!=null;seqsmooth = seqsmooth->h_next) { cvseq * newseq = cvcreateseq(cv_32fc1,sizeof(cvseq),sizeof(cvpoint),storage); for(int =3 ; i<seqsmooth->total-2 ;i++) { cvpoint * ps1 = cv_get_seq_elem(cvpoint,seqsmooth,i-2); cvpoint * ps2 = cv_get_seq_elem(cvpoint,seqsmooth,i-1); cvpoint * ps3 = cv_get_seq_elem(cvpoint,seqsmooth,i); cvpoint * ps4 = cv_get_seq_elem(cvpoint,seqsmooth,i+1); cvpoint * ps5 = cv_get_seq_elem(cvpoint,seqsmooth,i+2); cvpoint newpoint = cvpoint((ps1->x + ps2->x + ps3->x + ps4->x + ps5->x)/5,(ps1->y + ps2->y + ps3->y + ps4->y + ps5->y)/5); cvseqpush(newseq,&newpoint); } if(storagecontour->bottom->prev != null) { cvmemblock * oldnext = storagecontour->bottom->next; cvmemblock * oldprev = storagecontour->bottom->prev; storagecontour->bottom = newseq->storage->bottom; storagecontour->bottom->next = oldnext; storagecontour->bottom->prev = oldprev; } else { cvmemblock * oldnext = storagecontour->bottom->next; storagecontour->bottom = newseq->storage->bottom; } }

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
