Query about "AcDbDatabase::readDwgFile" input

[Bhong.ND]

Hi,

Whether is it ok to pass relative file path as input to "AcDbDatabase::readDwgFile" method?

In our application, we traverse xRef graph.

These xRefs can be stored with relative path to the main parent drawing.

While debugging xRef traversal, found that "AcDbDatabase::readDwgFile" is working fine with relative paths on Windows xp (64 bit) machines but same code is failing on Windows 7 (64 bit) machine.

Also tried similar code in an independent test arx command  on Windows XP (64 bit) but there also "AcDbDatabase::readDwgFile" is failing for relative paths and working fine with full paths.

So confused with expected input for "AcDbDatabase::readDwgFile".

If full path is always requried for ""AcDbDatabase::readDwgFile" then why it is working fine in my main application on XP where relative paths were given.

Thanks a lot for your time and support.

With regards

ND.

I would guess that readDwgFile will open files relastive to the current working directory, whereas the xref path is relative to the directory containing the host database drawing file. I don't think you can assume these are always the same directoryor  using the same search path.
