SSH SendReqExec — Interactive Commands such as “more”
Commands that assume an interactive user at a shell prompt should not be passed to SendRequestExec. For example, the “more” command assumes there is a shell and that the user will press RETURN when another screenful of text is wanted. It would be more appropriate to use the Unix/Linux “cat” command w/ SendRequestExec. To run […]
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 […]

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 […]
Verify UnlockComponent Success w/ Purchased Unlock Code
To manually verify that a valid purchased unlock code was passed to UnlockComponent, examine the contents of the LastErrorText after calling UnlockComponent or UnlockBundle. The following message indicating a purchased unlock code was used should be present: “Component successfully unlocked using purchased unlock code.” See below: ChilkatLog: UnlockBundle: DllDate: Jul 23 2016 […]
LastErrorText Standard Information
All Chilkat classes / components use a property named LastErrorText. It provides a way to get detailed information about what happened during any Chilkat method call. The LastErrorText will contain information even when the method call is successful. In almost every case, the LastErrorText will begin with information such as this: ChilkatLog: Decrypt: DllDate: Nov […]
UnlockComponent LastErrorText shows exact string passed to it.
If the string argument passed to UnlockComponent or UnlockBundle is NOT a purchased unlock code, then the LastErrorText will contain the exact string passed to it by your application. In this case, the string “Hello World” was passed to UnlockBundle. If UnlockComponent returns 0/false, check carefully the exact string being passed to it. Make sure […]
