Hello,
I am writing a plugin using the managed wrapper provided by Autodesk (Max 2014) for the Max SDK.
I would like to write to the Max log file, which I believe I do through the LogSys object, however something goes wrong whenever I try to do so.
I get an instance of ILogSys from the global interface and call LogEntry() on it like so:
logger.LogEntry(SYSLOG_INFO, false, "MyPlugin", "%s
", message);
Where message is a regular string, with nothing fancy in it.
In the Max.Log file however I get:
2013/12/29 20:53:11 INF: [125716] [125720] [I]bs[/I]
Where bs is the ‘backspace’ character according to Notepad++.
Is there anything special I have to do when using this method in the wrapper? Specify how the strings should be marshaled explicitly? Convert them?
Where message is a regular string, with nothing fancy in it.
what type is it exactly ?
if its a “regular” c# string class then try
message.ToCharArray();
or Max CStr try
message.data();
or is it ?
char[] message;
EDIT
OK I fixed it/came up with a workaround:
logger.LogEntry(SYSLOG_INFO, false, "DazMaxBridge", message + "
");
Or if you like
logger.LogEntry(SYSLOG_INFO, false, "DazMaxBridge", string.Format("{0}
",message));
(It took far too long for me to think to do that. I know the expression “woods for the trees” but this is being unable to see the garden for the sickly Dwarf Willow tree in the corner…)
Hi Klunk,
It is a regular C# string. I tried ToCharArray() and the character became a question mark, so I then tried Encoding.ASCII.GetBytes(message) and the character became a dash (-)!
In the Max SDK documentation they use this _M() macro, does this create a Max CStr you mentioned? I wonder if I need to convert to this.
It occurred to me that whether I add a null terminator or not, that the log always displays a single character (and it changes depending on what type of object I pass), so maybe its reading the reference as the data.
I tried to fix the string in memory and send a pointer directly with
fixed (char* msgPtr = message.ToCharArray())
But the method will not accept a char* in place of an object.
I then tried to use
Marshal.StringToHGlobalAuto(message)
and pass an IntPtr but this has the same issue as passing any other managed object.
