问题描述
我用一个Thrad过程函数ThreadProc制作了一个视图文件.编译时会出现如下错误:
ThreadDemoView.cpp(114):错误C2146:语法错误:丢失;在标识符``ThreadProc''之前;
ThreadDemoView.cpp(114):错误C2501:UNIT; :缺少存储类或类型说明符
严重错误C1004:发现文件意外结束
执行cl.exe时出错.
我是MFC的新手,请帮忙.
I have made one view file with one Thrad procedure function ThreadProc. While compiling it gives error as:
ThreadDemoView.cpp(114) : error C2146: syntax error : missing ; before identifier ''ThreadProc'';
ThreadDemoView.cpp(114) : error C2501: UNIT; : missing storage-class or type specifiers
fatal error C1004: unexpected end of file found
Error executing cl.exe.
I am new in mfc please help.
