ReadFile() Reads the contents of a binary file previously opened using OpenFile(). Syntax ReadFile(<cFile>, <nBytes>) --> cData Arguments <cFile> --> is the name of the file to read from disk. A path and drive letter should be specified if applicable. <nBytes> --> The number of bytes to read from the file. This should be in the range 0 to 65535. Returns Returns the data read from the disk file as a string. The length of cData indicates the number of bytes successfully read in. If the length of cData is zero or the length of the file is less than <nBytes> than either an error has occurred or you have read to the end of the file. Description This function is used to read the contents of a binary disk file. The file must already have been opened using OpenFile(). After you have completed reading the file, it must be closed using CloseFile(). Example cFile := "C:\CAPITAL\Mydata.dat" cData := "" If OpenFile(cFile) * Read all data from file and store * in cData 2048 bytes at a time * :LoopRead cData := ReadFile(cFile, 2048) If ( Len(cData) == 2048 ) Goto LoopRead * If length of cData is less than 2048, * there is no more data left to read from * the file CloseFile(cFile) ____________________________ Related Topics |
