我是新手根据张帆的编写了个2004的程序，是将TXT文件导入到CAD的，不知道为什么不能将实体多线段和文字放到相应的图层
以下是代码（写的代码可能有点乱，顺便我想将函数放到类里，不知道怎么的老出错）
static void hhabc_abc(void)
{
//选择文件
const char* title = "选择图形文件";
const char* path = "d:\\";
struct resbuf *FileName;
FileName = acutNewRb(RTSTR);
if (acedGetFileD(title, path, "txt;dat", 0, FileName) == RTNORM)
{
acutPrintf(FileName->resval.rstring);
}
// 打开所要导入的文本文件
CStdioFile f;
CFileException e;
if (!f.Open(FileName->resval.rstring, CFile::modeRead, &e))
{
acutPrintf("\n打开导入文件失败！");
return;
}
acutRelRb(FileName);
// 获得层表指针
AcDbLayerTable *pLayerTbl;
AcDbLayerTableRecord *pLayerTblRcd;
acdbHostApplicationServices()->workingDatabase()
->getLayerTable(pLayerTbl, AcDb::kForWrite);
// 读取文件中的每一行数据
CString strLineText; // 一行文字
int hh = 1;
while (f.ReadString(strLineText))
{
// 跳过空行
if (strLineText.IsEmpty())
continue;
// 解析出图层名称、颜色、线型和线宽
CStringArray layerInfos;
if (!GetFieldText(strLineText, layerInfos))
continue;
// 创建新的层表记录，或者打开存在的块表记录
AcDbLayerTableRecord *pLayerTblRcd;
AcDbObjectId layerTblRcdId;
if (pLayerTbl->has(layerInfos.GetAt(0)))
{
pLayerTbl->getAt(layerInfos.GetAt(0), layerTblRcdId);
}
else
{
pLayerTblRcd = new AcDbLayerTableRecord();
pLayerTblRcd->setName(layerInfos.GetAt(0));
pLayerTbl->add(layerTblRcdId, pLayerTblRcd);
}

望有大虾指点一二，先谢谢了 |
