Binary text file manipulation
Richard Barker 24 November 2004 16:22:23
	Hi I am FTP'ing some fixed length ascii text files from an mainframe computer to my windows box and importing them into an SQL data warehouse. The problem I have is, if I use ascii as a transfer option, some of the European characters disappear from the text. If I use the binary option, they appear correctly, but the carriage returns and line feeds are, effectively, missing, so the file is one big blob. I need to restore the file, so each record length is 318 bytes.

	Unix uses only a carriage return so the linefeed character is missing doing an ASCII ftp inserts the missing line feed character but sometimes destroys other data, you should be able to get away with replacing all carriage return characters with a carriage return & linefeed character. -----Original Message----- From: Discussion relating to the specifics of the C# and Managed C++ languages [mailtoOTNET-CX@DISCUSS.DEVELOP.COM] On Behalf Of Richard Barker Sent: 24 November 2004 11:55 AM To: DOTNET-CX@DISCUSS.DEVELOP.COM Subject: [DOTNET-CX] Binary text file manipulation Hi I am FTP'ing some fixed length ascii text files from an mainframe computer to my windows box and importing them into an SQL data warehouse.

	BTW the string.Replace() only allows you to replace a character with another character AFAIK, a workaround might be to reference the VB namespace and use the VB replace which allows you to replace a string with another string or in your case one character "\r" with two characters "\r\n". -----Original Message----- From: Discussion relating to the specifics of the C# and Managed C++ languages [mailtoOTNET-CX@DISCUSS.DEVELOP.COM] On Behalf Of Richard Barker Sent: 24 November 2004 11:55 AM To: DOTNET-CX@DISCUSS.DEVELOP.COM Subject: [DOTNET-CX] Binary text file manipulation Hi I am FTP'ing some fixed length ascii text files from an mainframe computer to my windows box and importing them into an SQL data warehouse.

No, you're wrong. There are two overloads for string.Replace - one is string.Replace(char, char), and the other is string.Replace (string, string). No need to look to VB.
