StreamWriter sw = new StreamWriter(@"c:\windows\zamma\zamma.txt");
sw.Write(textBox3.Text);

Put a breakpoint in the code then debug and single-step through the code. That will help to ensure that the code is executing. You can do that without changing the source code.

Something else to do is to use a try/catch block to catch errors. There might be an error happening that you don't see.

"I press to F5 to run my program,and edit the text,then press to my"save"button.But nothing changes in the text file..."

Maybe your save button isn't programmed correctly? The code you posted is OK, that's why I ask.

I tried sw.Flush() but it didn't do anything different...I think I must move the file to another path excluding c:\windows (with codes)then edit it and move again to where must it be.I think-at least-I can do this.Thanks for your help.

Thank you, Abdullah for providing this critical additional information. Try calling sw.Flush() before sw.Close().

Why are you asking if there is something wrong with your code? Is it not working? If so then you need to say that it is not working and you must say what happens. I assume there is an error message; what is the error message? If the error message is in English, then please copy and paste it here to ensure you get the complete and accurate error message. If it is not in English, then please try to translate the entire error message as accurately as possible.

I am using XP but it doesn't work...Perhaps I have no permission for this path...Thank you for replying.

This code is work fine in XP but probably you get problem in VISTA or Windows 7 as "you have no permission for c:\windows\.. folder" is not it? you may access othe folder like D:\abc\xyz\

Thank you!
