I am trying to send an attachment file using MSMAPI.
I disable AttachmentIndex, attachmentPosition, attachmentType, attachmentPathName and attachmentName and work. But when I enable them i receive the following error message:
OLE IDispatch exception code 0 from MAPIMessages: Unspecified failure has occured.
Can anybody help me... Thanks in advance.

My code is this

If .LogSession
.OleMMess.sessionid=.OleMSess.sessionid
.OleMMess.compose
.OleMMess.msgnotetext= _screen.ActiveForm.gcMensaMail
.OleMMess.MsgIndex = -1
For i = 1 to aLen(_screen.ActiveForm.gaDesti)
.OleMMess.RecipAddress = _screen.ActiveForm.gaDesti[i]
.OleMMess.msgsubject= _screen.ActiveForm.gcSubject
.OleMMess.AttachmentIndex = .OleMMess.AttachmentCount + 1
* .OleMMess.AttachmentPosition = len(_screen.ActiveForm.gcMensaMail)
* .OleMMess.AttachmentType=0
* .OleMMess.AttachmentPathName = _screen.ActiveForm.gcAttachPath
.OleMMess.AttachmentName = _screen.ActiveForm.gcAttachName
.OleMMess.send(0)
Next i
If .LogSession
.OleMSess.signoff
Endif
Endif
