Remarks

Solve performs network analysis based on the solver properties and network locations in the NAContext.

It returns :

• True if a partial solution has been found (e.g. some stops are unreachable but a partial route exists).
• False if the whole solution has been found.

Additionnally, Solve returns informational messages in the GPMessages object. Each GPMessage contains a description and may have a naError code. Message types returned are:

• esriGPMessageTypeError when the solve fails (the analysis problem is incorrectly defined or the problem is unsolvable).
• esriGPMessageTypeWarning when a partial solution is found.
• esriGPMessageTypeAbort when the user aborts the analysis by pressing the ESC key.
