大侠哥哥们请帮忙小妹快哭出来了

feel_cy · 发表于 2004-11-2 16:12:00

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[300],yy[300];
int i=0;
void read_data()
{
   FILE *fp;
     float px,py,pz;
   fp=fopen("planestation1.txt","wr");
   char x[20],y[20];
   while(!feof(fp))
   {
   if (fscanf(fp,"%s%s",x,y)==EOF)
   break;
   xx[i]=atof(x);
   yy[i]=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？

feel_cy · 发表于 2004-11-3 11:07:00

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。

easypower · 发表于 2004-11-3 11:07:00

double xx[300],yy[300];
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();
}
}
