Chilkat 9.1.0 Release Notes

HTTP:  Fixed problem with setting Content-Type header in HTTP POST to text/namevalue (which is required for POSTs to payflowpro.paypal.com).  The POST body was URL encoded when it shouldn’t have been.  When sending namevalue POSTs to payflowpro, be sure to specify the content-type in the HTTP request object:  requestObject.AddHeader(“content-type”,”text/namevalue”) SSH / SFTP: For AuthenticatePw, if the server’s authentication is keyboard-interactive and […]

SSH SendReqExec — Commands with No Output

When a command is passed to SendReqExec that produces no output, such as “echo 1 > test.txt”, then do not try to read the channel (such as by calling ChannelReadAndPoll) because no data will be forthcoming and the channel read will timeout (as expected). The correct sequence of method calls would be to: Call SendReqExec to execute the command on […]

SSH/SFTP Downloading Text file produces strange characters?

Question: I receive strange characters when downloading a text file using ReadFileText. Why does this happen? Answer: Using SSH/SFTP, files are downloaded exactly as-is byte-for-byte except if you call the ReadFileText* methods. The ReadFileText* methods require a charset (i.e. character encoding) to be specified in the method arguments. This allows the method to interpret the bytes according to a specific […]
