微软OCR控件 vb 调用 modi

利用微软OCR控件, 只需要不到10行代码就能够实现自已的OCR文字识别软件. 1. 添加控件,需要安装office2003, 没有安装office2003的可以从别人机子上拷贝相关文件,注册regsvr32.exe mdivwctl.dll, 控件一般在这个目录下:C:/Program Files/Common Files/Microsoft Shared/MODI.0, 只需要相关的几个文件就可以了, 此文件夹全部文件大概在21M左右. 2.工程->部件->添加这个控件:Microsoft Office Document Imaging 11.0 Type Library
