zxtnt09 1 Posted January 3, 2016 Look at the help file for FileOpen.i use that but still don't action !$FileOpen = FileOpen($FileDir,256) Share this post Link to post Share on other sites
VIP 55 Posted January 3, 2016 $hFileOpen = FileOpen($sFile,16); $FO_BINARY (16) = Force binary mode Regards, Share this post Link to post Share on other sites
zxtnt09 1 Posted January 3, 2016 $hFileOpen = FileOpen($sFile,16); $FO_BINARY (16) = Force binary mode Still not working !!!!!important part for me is "String repleace" , i need to repleace "NULL" to "Hello" but not working,for do that , i should open file and click on "UTF-8-BOM" after i click that i can replace !!!( if i click on UTF-8-BOM some of data in file was change ! ) Share this post Link to post Share on other sites
Malkey 231 Posted January 3, 2016 You could try this.; Create test file "fkz51t.txt" Local $hFileOpen = FileOpen("fkz51t.txt", 2) Local $FileContents = _ ChrW(0) & ChrW(0) & ChrW(0) & ChrW(5) & ChrW(3) & @CRLF & _ ChrW(0) & ChrW(0) & ChrW(0) & ChrW(0) & ChrW(4) & @CRLF & _ ChrW(0) & ChrW(0) & ChrW(0) & ChrW(0) & ChrW(4) & @CRLF & _ ChrW(0) & ChrW(0) & ChrW(0) & ChrW(0) & ChrW(4) FileWrite($hFileOpen, $FileContents) FileClose($hFileOpen) ; Replace Null with "Hello" Local $hFileOpen = FileOpen("fkz51t.txt", 16) Local $data = StringReplace(FileRead($hFileOpen), "00", StringTrimLeft(StringToBinary("Hello"), 2)) ; "00" (binary) = ChrW(0) = null FileClose($hFileOpen) FileDelete("fkz51t.txt") ; Write modified file contents to file FileWrite("fkz51t.txt", BinaryToString($data)) ; Display contents of file. ConsoleWrite(FileRead("fkz51t.txt") & @LF) 1 zxtnt09 reacted to this Share this post Link to post Share on other sites
zxtnt09 1 Posted January 3, 2016 @Malkey , thanks it's great but have a little problem and it's clear all of other file content!it's meant : "in this file we have" NULL NULL NULL NULL NULL BS NULL NULL NULL NULL SOH ETB NULL Some data 2015 blah blah ; the data by each refresh will be change , but i want to clean just null not all of content Share this post Link to post Share on other sites
Malkey 231 Posted January 3, 2016 This example removes only null characters. This works for me on Win 10.; Create test file "fkz51t.txt". Local $sFileName = "fkz51t.txt" Local $hFileOpen = FileOpen($sFileName, 2) Local $FileContents = _ ChrW(0) & ChrW(0) & ChrW(0) & ChrW(0) & ChrW(0) & ChrW(8) & @CRLF & _ ChrW(0) & ChrW(0) & ChrW(0) & ChrW(0) & ChrW(1) & ChrW(23) & @CRLF & _ ChrW(0) & "Some data 2015 blah blah" FileWrite($hFileOpen, $FileContents) FileClose($hFileOpen) ; Remove all Nulls. Local $hFileOpen = FileOpen($sFileName, 16) Local $data = StringReplace(FileRead($hFileOpen), "00", "") ; Replace all "00" (binary) with "" (nothing). FileClose($hFileOpen) FileDelete($sFileName) ; Write modified file contents to file. FileWrite("fkz51t.txt", BinaryToString($data)) ; Display contents of file. ConsoleWrite(FileRead("fkz51t.txt") & @LF) Returns the file contents of:-BS SOH ETB Some data 2015 blah blah Share this post Link to post Share on other sites
zxtnt09 1 Posted January 4, 2016 (edited) BS SOH ETB �Some data 2015 blah blah yes it's true , but it was overwrite and remove all of things ( without data in "Local $FileContents" )actuley i don't know "some data 2015 blah blah ..." it was modify by each refresh! ( example : going to "some data 2016 halb blah" )so i should repleace "NULL" and "SOH" with "Blank".please see this , the data will be modify by each refresh , so i should remove just "NULL" and other data (the data i don't know) should not be remove.sorry for bad english.thanks Edited January 4, 2016 by zxtnt09 Share this post Link to post Share on other sites
Rampantshadow 0 Posted January 5, 2016 what would be the ideal data that you would like left in the file? just the date for example, or did you just want to get rid of the blanks and leave all other data? Share this post Link to post Share on other sites
zxtnt09 1 Posted January 5, 2016 what would be the ideal data that you would like left in the file? just the date for example, or did you just want to get rid of the blanks and leave all other data? Yes it's true , i want to change (repleace) just "NULL" data and leave other data. Share this post Link to post Share on other sites
Rampantshadow 0 Posted January 5, 2016 (edited) firstly if you want to open the file in UTF8-BOM you need to$FileOpen = FileOpen("test.txt", 1 + 256) ;This will allow you to Append the File and open it in UTF8-BOM $string = FileRead($FileOpen) FileClose($FileOpen) $charReplace = StringReplace($string,'NUL',"",0) FileDelete("test.txt") $FileOpen = FileOpen("test.txt", 2) ;this will write an new file not saved as UTF8-BOM but as ANSI FileWrite($FileOpen,$charReplace)Hopefully this should work for what you need it to do, I honestly haven't tested it but it should be close to what you want.
