大侠哥哥们请帮忙 小妹快哭出来了
本帖最后由 作者 于 2004-11-3 11:11:53 编辑 <br /><br /> 我就想从文件里面读出x，y坐标，然后循环画点。可是我这样写根本画不出来。要是我把读文件那段函数写在drawplanestation()主程序里，在运行cad时，就说我犯了致命的错误。各位大哥快请帮帮小妹我吧！！<BR><BR>void initApp()<BR>{<BR> acedRegCmds->addCommand("drawplanestation_COMMAND",<BR> "planestation",<BR> "1",<BR> ACRX_CMD_TRANSPARENT,<BR> drawplanestation);<BR> <BR>}double xx,yy; <BR>int i=0;

请问怎样设断点调试呀，在Arx框架下？一按执行就调出cad界面了。 double xx,yy;
重復定义两次！！
read_data()函数里面把外面的定义隐藏了！！
外面数据为空！！

要不在你的机器上先运行一下看看？
