i need to create small dll to intercept simple mapi calls and send files via:
file->Send to as attachment (in excel, word, acrobat reader...)
or via explorer->rightclickmenu->Send to->Mail recipient
to attach to gmail.
after reading this:
Mapi32.dll Stub Registry Settings (Windows)
Mapi32 Stub Library (Windows)
and searching here on stackoverflow and other webs i have created one very small dll using code::blocks that shows me information for investigating the process.
I have installed it on registry correctly like indicated in previous links on HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\SimpMapi.
I have selected on my win xp pro in control panel->Internet options my SimpMapi client.
when i open excel write some cells and go to File->Send like attachment dll shows me that first calls MapiLogon, second calls MapiSendMail and third when i close excel it calls MapiLogoff, but then it throws an error and closes excel.exe.
If i try it from explorer window right clicking one file and SendTo->Mail recipient it calls directly MapiSendMail and when i click on ok in MsgBox it throws an error and closes explorer.exe
Could you help me to find out what is wrong.
This is the mail.h file:
