myspacee Posted January 8, 2009 Share Posted January 8, 2009 (edited) hello to all, need help to understand _FileWriteToLine. Use to build HTML page, all work fine until i want to use variable in line to write. Write small code to explain better my problem: - create file - random number - write to first line - msgbox to user - udf read first value and assign to variable - _FileWriteToLine overwrite first line with modified value #include <file.au3> global $RESULT ;//////////////////////////////////////////////////////////////////// ; create text file with random value in first line ;//////////////////////////////////////////////////////////////////// $FILE = FileOpen(@ScriptDir & "\Metric_value.txt",10) sleep(1000) FileWrite($file, string(Random(10000, 99999, 1))) FileClose($FILE) ;//////////////////////////////////////////////////////////////////// ; function read from above random generated text file ; and return value into variable ;//////////////////////////////////////////////////////////////////// _ret_metric_value() msgbox(0,"",$RESULT) ;//////////////////////////////////////////////////////////////////// ; doesn't work - replace 1st line in file with modified value (add some test text) ;//////////////////////////////////////////////////////////////////// _FileWriteToLine((@ScriptDir & "\Metric_value.txt", 1, "->> " & $RESULT & " <<-", 1) ;//////////////////////////////////////////////////////////////////// ; find metric value after compare images ;//////////////////////////////////////////////////////////////////// Func _ret_metric_value() $FILE = FileOpen(@ScriptDir & "\Metric_value.txt",0) $RESULT = FileRead($FILE) FileClose($FILE) Return $RESULT EndFunc i must use my UDF _ret_metric_value() because this file in my production, store value generated from DOS command (numeric delta value from image differences process) what is wrong ? thank you, m. ___ EDIT modify script because find an error, now works, but can't replicate my production problem...

Works fine if you take out the stray open paren in _FileWriteToLine(): #include <file.au3> Global $RESULT, $FILE $FILE = FileOpen(@ScriptDir & "\Metric_value.txt", 10) Sleep(1000) FileWrite($FILE, String(Random(10000, 99999, 1))) FileClose($FILE) _ret_metric_value() MsgBox(0, "", $RESULT) _FileWriteToLine(@ScriptDir & "\Metric_value.txt", 1, "->> " & $RESULT & " <<-", 1) _ret_metric_value() MsgBox(0, "", $RESULT) Func _ret_metric_value() $FILE = FileOpen(@ScriptDir & "\Metric_value.txt", 0) $RESULT = FileRead($FILE) FileClose($FILE) Return $RESULT EndFunc ;==>_ret_metric_value So what's the new problem...?
