[B]如何获得ARX的路径 [/B]

用下面的方法，可以获得所有加载过的ARX文件信息到一个AcDbVoidPtrArray 结构中

2. <normalfont>
   
3. 
   
4. Global Functions
   
5. 
   
6. AcRx Global Functions
   
7. 
   
8.   acrxLoadedApps
   
9. 
   
10. Include File
    
11. 
    
12. rxregsvc.h
    
13. 
    
14. void*
    
15. 
    
16. acrxLoadedApps();
    
17. 
    
18. This function returns a pointer to an AcDbVoidPtrArray that contains copies of the file names or URLs of all the currently loaded ObjectARX applications. These are the same strings that are reported by the AutoCAD ObjectARX command's "?" option.
    
19. It is the caller's responsibility to free all the strings in the array and to delete the array itself when finished with it.
    
20. </normalfont>

不行啊!!!!
        void *ppp = acrxLoadedApps();
        AcDbVoidPtrArray *p = (AcDbVoidPtrArray*)ppp;
        for (int i=0;i<p->length();i++)
        {
                char *pp =(char*) p->at(i);
        }
        delete ppp;
返回的是ARX的文件名,不是路径!!

知道文件全名就好办了。
以下是一段代码, 供参考, arxPath 即是该arx自身所在path

1. 
   
2.     // ...
   
3.     TCHAR dir[_MAX_DIR], drive[_MAX_DRIVE], arxPath[_MAX_PATH], fullpath[_MAX_PATH];
   
4.        
   
5.     GetModuleFileName( _hdllInstance, fullpath, _MAX_PATH );
   
6.        
   
7.     _tsplitpath(fullpath, drive, dir, NULL, NULL);
   
8.     _tmakepath(arxPath, drive, dir, NULL, NULL);
   
9.     //....
   

复制代码

其实arx还提供了一个CAcUiPathname 类，可以用于文件名解析。

binbin

非常感谢rave,这样就可以通过已加载的ARX得到软件的安装目录了.我以前是通过写注册表.
我想问一下CAcUiPathname 怎用?

fundoll

_tsplitpath(fullpath, drive, dir, NULL, NULL);
    _tmakepath(arxPath, drive, dir, NULL, NULL);
是什么宏? 要引用什么头文件!
