You can store the number of lines in the infolog before entering a try block:

int startLine = infolog.line();

And in the catch block get all the messages that have been added in the try block:

str msg; int currentLine; // ... for (currentLine = startLine + 1; currentLine <= infolog.line(); currentLine++) { msg += infolog.text(currentLine); }

To get only the last message you can use a code like this:

str msg; // ... if (infolog.line() > startLine) { msg = infolog.text(); }

I think you didn't understand my question.

I don't know what happens in the try block (It's a 3rd party function - I cannot change - kind of "black-box") but I know that this function throws an exception.

I want to know what kind of exception (what message, what message-no, if any, etc ...) How can I know that ?

Thanks :)

If we are still talking about AX then there are just a few situations when you cannot change the code you're calling from X++ and all of them are related to some kind of interop: COM/.NET/DLL. Is this your case?

We are still talking about AX.

I don't understand : Can I get the last error string or not? If I can - then how

(I just need to know what to tell the 3rd party company what error in order to get in progress).

Thanks :)

Yes, you can get but... There can be four main scenarios in your case:

You call X++ code - in that case you can use the sample code provided earlier;

If you call .NET code - use AifUtil::getClrErrorMessage();

If you call a DLL function - use WinAPI::getLastError() or WinAPIServer::getLastError() and then format the message according to error code;

If you invoke a COM object - use COM.getError() to get a COMError object an retrieve the message via COMError.description().

If you directly call .NET/COM/DLL and try to get the error message from the infolog then you'll get a "stub" message like "An error occurred when invoking CLR class". But if you process an order then you most likely call X++ code so you can just call infolog.text().
