I am using COM server *.dll's in my VB6 applications. The statistical routines that is being calculated in fortran takes a while and I have got a problem in that VB does not know when the COM Server has been finished.
1) Is it possible to let VB know when the COM server is finished?
2) " to let VB know how far the process in the COM server is? This would make it possible to give the user in VB a nice progress bar.
( I did find some code in the old normal DLL samples, which worked - but how do I make it work in COM server )
On the VB side
Declare Sub Stats Lib "c:workinstats.dll" (Ret As Long, ByVal cb3 As Long)
Private Sub cmdRun_Click()
Call Stats(test, AddressOf ghproc3)
Public Sub ghproc3(p1 As Long)
frmView.lblProgress.Caption = p1
On the Fortran side -
!rest of code
Otherwise the COM server works very nice with VB and it is lightning fast. ( I grew up in the VB3 days )
