大侠哥哥们请帮忙 小妹快哭出来了
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！！void initApp()
{
acedRegCmds->addCommand("drawplanestation_COMMAND",
"planestation",
"1",
ACRX_CMD_TRANSPARENT,
drawplanestation);
} double xx,yy;
int i=0;
void read_data()
{
FILE *fp;
float px,py,pz;
fp=fopen("planestation1.txt","wr");
char x,y;
while(!feof(fp))
{
if (fscanf(fp,"%s%s",x,y)==EOF)
break;
xx=atof(x);
yy=atof(y);
i=i+1;
}
fclose(fp);
}
void drawplanestation()
{
AcDbObjectIdArray idArray;
float px,py,pz;
read_data();
for (i=0;isetColorIndex(3);
AcDbBlockTable *pBlockTable;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pBlockTable,AcDb::kForWrite);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
pBlockTable->close();
AcDbObjectId pointId;
pBlockTableRecord->appendAcDbEntity(pointId,po);
po->close();
pBlockTableRecord->close();
return pointId;
delete [] po;
}
void unloadApp()
{
acedRegCmds->removeGroup("drawplanestation_COMMAND");
}
请把你的坐标文件也贴上来吧! 谢谢这位版主，以下是文件内容：左边是x坐标，右边是y坐标。

你单步调试试试看，数组有没有读对值？ 在Arx框架下，我不会单步调试。我在mfc框架下调试过，可以读。
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！！
for (i=0;isetPosition(pt);
AcDbBlockTable *pBlockTable;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pBlockTable, AcDb::kForRead);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord, AcDb::kForWrite);
pBlockTable->close();
AcDbObjectId ptId;
pBlockTableRecord->appendAcDbEntity(ptId, ptObj);
pBlockTableRecord->close();
ptObj->close();
}
}
