我想讓使用者選擇資料夾，接著把資料夾內的所有圖片讀取出來，全部作AND運算

只是會一直出錯，想問到底問題出在哪裡？

裏頭的檔案是事先存好的 檔名是由2開始

麻煩各位幫忙了！

[code cpp]
void __fastcall TForm1::Button1Click(TObject *Sender)
{
AnsiString hpath ;
hpath = DirectoryListBox1->Directory; //使用者所選擇的資料夾路徑
int img_num = 2;
ProgressBar1->Max = FileListBox1->Count; //執行跑馬條
IplImage* imga = NULL;
IplImage* imgb = NULL;
IplImage* result_img = NULL;

result_img = cvLoadImage( (hpath char(img_num) ".jpg").c_str() , CV_LOAD_IMAGE_COLOR );
imga = cvCreateImage(cvSize(result_img->width,result_img->height), IPL_DEPTH_8U,1); //此行編譯出錯
//作AND運算
while(img_num < FileListBox1->Count)
{
ProgressBar1->Position = img_num;
img_num ;
cvCopy(result_img,imga,0);
imgb = cvLoadImage( (hpath char(img_num) ".jpg").c_str(), CV_LOAD_IMAGE_COLOR );
cvAnd( imga, imgb, result_img , 0);
}
cvReleaseImage(&imga);
cvReleaseImage(&imgb);
cvReleaseImage(&result_img);
}
[/code]
