GetDOSFilename( filename ), VIRTUAL

blk2blue.jpg

GetDOSFilename Prompts the end user to select the file to process.
filename The label of the ASCIIFile property's NAME attribute variable which receives the selected filename.

The GetDOSFilename method prompts the end user to select the file to process and returns a value indicating whether the end user selected a file or did not select a file. A return value of one (1) indicates a file was selected and filename contains its pathname; a retun value of zero (0) indicates no file was selected and filename is empty.

Implementation:

The GetDOSFileName method uses a SelectFileClass object to get the filename from the end user.

Return Data Type:     BYTE

Example:

MyAsciiFileClass.Reset FUNCTION(*STRING FName)

RVal      BYTE(True)

SavePath  CSTRING(FILE:MaxFilePath+1),AUTO

 CODE

 CLOSE(SELF.AsciiFile)

 SavePath=PATH()

 LOOP

   IF ~FName AND ~SELF.GetDOSFilename(FName)

     RVal=False

     BREAK

   END

   OPEN(SELF.AsciiFile,ReadOnly+DenyNone)

   IF ERRORCODE()

     MESSAGE('Can't open ' & FName)

     RVal=False

   ELSE

     BREAK

   END

 END

 IF RVal

   SELF.FileSize=BYTES(SELF.AsciiFile)

 END

 SETPATH(SavePath)

 RETURN RVal
