hello all;
i have problem with saving char on the file

and i don't know where the file saved


	Code: void write() { TFileIOResult dIOResult ; Delete(FILENAME, dIOResult); TFileIOResult nIOResult ; TFileHandle LIGHTFILE ; int FileSize = index ; int i; OpenWrite ( LIGHTFILE , nIOResult , FILENAME , FileSize ); for (i=0;i < index ;i ++) { WriteByte ( LIGHTFILE , nIOResult ,arr[i] ); } Close ( LIGHTFILE , nIOResult ); }

Re: problem in file access

filesize = index? what is index?

Where/how is the variable FILENAME defined? I would also suggest you check the value of dIOResult after the OpenWrite to make sure it is 'no error'. From the robotc help file; "sFileName must be a valid NXT file name"

As far as I know, the NXT wants the filename to be something.DAT, and it will appear in the 'my files' menu on the NXT or in any remote file utility such as the 'robot->NXT brick->file management utility' in robotc.
