复现过程 首先,我创建了一个基于Picture Library的图片文档库,名字是 Pic Lib 创建完毕后,我点击它的Upload 下拉菜单,点击Upload Picture按钮 在弹出的对话框中点击 Upload Multiple Files按钮 结果返回了下面的错误页面 如果查看浏览器左下角还会发现JavaScript错误信息,全文如下: User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Tride

CStatic *pPic = (CStatic*)GetDlgItem(IDC_PICTURE); CBitmap bitmap; bitmap.LoadBitmapW(IDB_BITMAP2); pPic->SetBitmap((HBITMAP)bitmap.GetSafeHandle());//在Picture的Type调为Bitmap 像素修改: CStatic *pPic = (CStatic*)GetDlgItem(IDC_PICTURE); CBitmap bitmap; bitm

调试DeepFlow光流算法,由于作者给出的算法是基于Linux系统的,所以要在Windows上运行,不得不做大量的修改工作.移植到Windows平台,除了一些头文件找不到外,还有一些函数也找不到.这其中就涉及到三个函数:sgemv_,sgemm­,saxpy­_.百度了一下,原来这三个函数是很有来头的.它们仨来自于Basic Linear Algebra Subprograms(BLAS),即基础线性代数子程序库.这个库其实就是关于向量和矩阵之间的运算的. BLAS维百介绍:https://e
