Simple MAPI Console Application with Outlook Express.

[vshalarora82]

Hi All,

I am using Simle MAPI Console Application from
Microsoft([url]http://download.microsoft.com/download/mapi/utility/21/w9xnt4/en-us/smplmapi.exe[/url]).


It works fine when my default mail client is Outlook, but when my
default mail client is outlook express then it shows an error.

[MAPIAllocateBuffer (strlen ( rgchMsgID ) + 1, (LPVOID FAR*) prgchMsgID
);
strcpy ( *prgchMsgID, rgchMsgID );]

When program allocates memory for Message ID using MAPIAllocateBuffer,
then it returns 0x80004005. After that when strcpy executes, an
excetpion (0xC0000005: Access Violation) is generated.


If you know the cause, please help me.

Thanks,
Vishal Arora

Clearly that code is a sample not production code. If the
MAPIAllocateBuffer has failed you should not be trying to write to
where it ought to have put the allocated buffer.

You're experiencing a symptom of a problem that's presumably occurred
sometime before these immediate lines of code - you need to do some
more debugging and compare the results you get with Outlook and OE.

Hi David,

I came to know that MAPIAllocateBuffer is defined in Extended MAPI
header file. We can use only Simple MAPI with Outlook Express. So i
think we can't use MAPIAllocateBuffer with Outlook Express.
