[Tony_Stack]

hi all 

   i have a problem for coding to read 1D barcode.

the visual studio error is:

        error LNK2019: 无法解析的外部符号 __imp__imaqReadBarcode2@28，该符号在函数 "protected: virtual int __thiscall COCRFunctionDlg::OnInitDialog(void)" (?OnInitDialog@COCRFunctionDlg@@MAEHXZ) 中被引用
1>E:\VS2010\OCRFunction\Debug\OCRFunction.exe : fatal error LNK1120: 1 个无法解析的外部命令

when my use other function （pattern match or match sharp）not this error, but imaqReadBarcode2 or imaqReadBarcode3 have this error , imaqReadBarcode function have no error

.h file :

      #include "nimachinevision.h"
#include "niocr.h"
#include "nivision.h"
#include "io.h"
#pragma comment(lib,"nivision.lib")

have comment  library

please  help  very thanks

i think the command--"#pragma comment" doesn't work in labwindows. i got the same type error with you.so i copy the lib to my project folder and the error is gone.
