Hi
I've been having trouble getting basefile to work, I've been copying the example from the sdk

// Creates a filename that points to "foo.txt" in the plugin's directory
var filename = GeGetRootFilename();
filename->RemoveLast();
filename->Add("foo.txt");

// Creates the file and writes a string to it
var file = new(BaseFile);
file->Open(filename, GE_WRITE);
file->WriteString("Hello World!");

into the the <MyMenuPlugin::Execute(doc)> part of the "hello world 2" example along with some other code that extracts user data from each frame. The other code runs but nothing seems to happen with the new Basefile part. I also tried Matthias's

var fn = new(Filename);

if(!fn) return;

if(!fn->FileSelect("Create file", TRUE)) return;

var file = new(basefile);

if(!file) return;

if(!file->Open(fn, GE_WRITE, FILE_IGNOREOPEN, GE_INTEL)) return;

if(!file->WriteString("hallo", GE_7BIT)) return;

but I get an empty txt. file. I'm struggling to come up with something new to try.

Any help would be much appreciated.
Kind regards
Conor

I've attached the full code as well.

Hi I've found the problem (I should have left return off "if(!file->WriteString("hallo", GE_7BIT)) return;" It's working fine now. Is there a newline function in that can be used with WriteString?

C/C++/Java/COFFEE/etc.: newline '\n' character. This type of notation (with the \) is called an 'escape character' or 'escape sequence'. With it you can do things like (tab), \\ (actually print \), \0value (an ASCII/UniCode value, number). Do a Google search for 'escape sequence' and you'll get many links to lists of and information on them.

file->WriteString("Hallo\n", GE_7BIT);
