<br>内容：VC compiler will also show you what's the redefined symbol. Use "VC-&gt;Edit-&gt;Find in files..." to search for all the existences of this symbol, be sure that you defined it only once.<BR><BR>One reason for this error is that you declared a global variable in a .h file and include this file in several .cpp files. Don't declare global variables in .h files. Declare it in a .cpp file and use "extern VarType VarName;" in a .h file to export the variable.<BR>
