如题！

    AcDbDatabase* pDb;
    char *fname;
    struct resbuf *rb;

    rb = acutNewRb(RTSTR);
    int stat = acedGetFileD("Pick a drawing", NULL, "dwg", 0, rb);
   
    if ((stat != RTNORM) || (rb == NULL)) {
        acutPrintf("\nYou must pick a drawing file.");
        return;
    }

    fname = (char*)acad_malloc(strlen(rb->resval.rstring) + 1);
    strcpy(fname, rb->resval.rstring);
    acutRelRb(rb);
   
    pDb = new AcDbDatabase(Adesk::kFalse);
    if (pDb->readDwgFile(fname) != Acad::eOk) {

    }

    AcDbBlockTable *pBlockTable;
    pDb->getSymbolTable(pBlockTable, AcDb::kForRead);

已经解决，有两种模式可以打开，SDI和MDI文档！

小树袋熊

怎么解决！！！！！！
厉害!!!!!!!!!!!!

boaosun

看ObjectArx里面的例子！有方案！

小树袋熊

是那一个例子啊？楼主说明白点啦，
第一次学ARX，请多多包涵！！！！！！！！

boaosun

帮助里面也有说明！可以看帮助！

小树袋熊

把例子帖出来吧！！！！！！！！！
强烈要求！！！！！！！！！！！！

void openSyncDocHelper( void *pData)
{
    AcApDocument* pDoc = acDocManager->curDocument();
    if (acDocManager->isApplicationContext()) {
        acutPrintf("\nSucessfully Switched to App. Context\n");
        acDocManager->appContextOpenDocument((const char *)pData);
        acutPrintf("\nOpened a document synchronously:%s.\n", (const char *)pData);
    } else
        acutPrintf("\nERROR: in Document context : %s\n",pDoc->fileName());

}

//  NAME: openSyncDoc()

谢谢，
可以打开了，但是，原来已经打开的Drawing1.dwg怎么关闭？
使用
acDocManager->closeDocument(pDoc);
不灵啊

我是这样写的：
if (pDoc) {
acutPrintf("\nCurrently in Document context : %s, Switching to App.\n",pDoc->fileName());
acDocManager->executeInApplicationContext(openSyncDocHelper, (void *)pData);
acDocManager->closeDocument(pDoc);
}

会出现一个提示，说
Drawing1.dwg不能关闭，命令在执行

很好啊,谢谢
