-- [求助]想在foxtable中使用OCR图像识别DLL，应该怎么做？
最近有个项目希望说最好能实现文本和数字的图像识别功能，录入到表中。我看了看引用DLL库的内容不多，也不知道具体在foxtable中是怎么引用才可以，怎么看是托管DLL还是非托管等
1、Asprise OCR这个DLL可以用么？http://asprise.com/royalty-free-library/vb.net-ocr-barcode-reader-sdk-samples-docs.html
2、http://blog.csdn.net/nhudx061/article/details/23559849， http://www.cnblogs.com/stone_w/archive/2011/10/08/2202397.html
两个文章中写了调用方式，但是在foxtable中如何正确引用进来？

非托管dll，把dll拷贝到foxtable安装目录下，然后在全局代码里声明对应的函数即可
<DllImport("AspriseOCR.dll", EntryPoint := "OCR", CallingConvention := CallingConvention.Cdecl)> _
Public Function OCR(file As String, Type As Integer) As IntPtr
End Function
<DllImport("AspriseOCR.dll", EntryPoint := "OCRpart", CallingConvention := CallingConvention.Cdecl)> _
public Function OCRpart(file As String, Type As Integer, startX As Integer, startY As Integer, width As Integer, height As Integer) As IntPtr
End Function
<DllImport("AspriseOCR.dll", EntryPoint := "OCRBarCodes", CallingConvention := CallingConvention.Cdecl)> _
Public Function OCRBarCodes(file As String, Type As Integer) As IntPtr
End Function
<DllImport("AspriseOCR.dll", EntryPoint := "OCRpartBarCodes", CallingConvention := CallingConvention.Cdecl)> _
Public Function OCRpartBarCodes(file As String, Type As Integer, startX As Integer, startY As Integer, width As Integer, height As Integer) As IntPtr
End Function

偶，非常感谢，确实可以读取DLL了，不过试了才发现，这个DLL对于中文不支持，不知道各位大侠有没有人介绍个可以使用的中文图像识别的DLL？

这里不是有介绍么？需要微软的库支持

回复5楼，这个是在vs里面操作的，你在vs里面操作以后，会生成一个dll文件，把dll文件在foxtable里面引用即可。
