I've tried opening a file in

"C:\Program Files\Winged Fighters\Data\TestStr.wfd"

But, the DarkSDK program or function won't be able to open it. The DarkSDK function I used is:

dbOpenToWrite (
1, "C:\\Program Files\\Winged Fighters\\Data\\TestStr.wfd" );

It won't be able to open the "TestStr.wfd" file if the path is like that. I'm thinking that it isn't able to open the file because of the spaces in "Program Files" and in "Winged Fighters". So, is that the problem? If so, how can I fix it. If not, what's the problem?

Hmmm, when I load images etc, I have to use slash instead of backslashes.
dbLoadImage( ID, "X://Dir1//Dir2//file.ext");

Please tell me if I am wrong


Alternatively to "fopen", you can use the std filestreams.

Its probably optional - I always use backslashes, but forward ones also seem to work.

Heh...
I've just implemented the win32api commondialog for open files and...
Actually, I could open (dbLoadObject) files with the filename/path returned by the commondialog.

So I can load (at least objects) with a filename like "SxyGuy" posted.
(with directorys seperated by single-backslash and also including spaces in directory-names: "X:\Dir 1\Dir2\file.x")


(Maybe this came in the 1.1 update or I was just "blinded"
by the samples/tutorials I've read

The string at the bottom is exactly the string I use with "dbLoadObject":
(The model is freely available and licensefree)

Allright, it seems you can use SINGLE slashes/backslashes when providing a FULL path.
When using RELATIVE path, you have to use DOUBLE slashes/backslashes.

FULL path:
"X:\Dir 1\Dir2\file.ext"

RELATIVE path:
"\\Dir 1\\Dir2\\file.ext"

Dont forget in C, a single \ treats the next character as an escape code - so, for a single one, you need two, eg :

"C:\\TEST\\FILE.INF"

If you did "C:\TEST\FILE.INF", it would treat \T as an escape code as well as \F

Hmm, right, as I pass the string to the db-function as an sz, this will avoid file from loading if an escape code was detected.

It seems like I was just lucky enough to have selected only files that don't create an escape code...

So its better to write a converter function that will replace the "\" with "\\"... hmm... sure a thing for the DarkGame code-snippets section...

It will only be a problem with literal and constant strings - values passed from APIs, for example will be okay.

In C & C++ the backslash is interpreted as 'the next character means something different from normal', but only within literal strings or literal characters within your C or C++ source code. That allows you to include newlines or tabs in strings for instance (\n and \t). To actually get a backslash you have to have two of them.
