ReadEventLog problems

Hi Guys,

No matter how I try to call the ReadEventLog API it always returns a value of 87 (ERROR_INVALID_PARAMETERS). So I am obviously trying to use the wrong variable types (or values). I have searched extensively across the web but can't find a solution.

Any hints or sample code would be appreciated.

DJ.

Yeah I guess that could be handy.. woops!

Using VB6

lReturnCode = ReadEventLog(lLogHwd, EVENTLOG_SEQUENTIAL_READ, lLogPos, VarPtr(Log), lNumBytesToRead, lBytesRead, lMinNumBytesNeeded)

Where all of the variables are of type long except bLog which is of type Variant. 56 is the value set into lNumBytesToRead and for the examle I am setting lLogPos to 1.

I have no problems opening the Event Log and counting the number of logs so the lLogHwd variable does hold the correct value.

Thanks,

DJ.

VB6 eh? In that case I'd suggest joining the VB5/VB6 forum (forum222) or even the forum specifically for using the API from VB(forum711).

As a shortcut, here's my demonstration code (from forum222) on reading the event log from VB: thread222-395506
