Is it possible to bring up the config dialog for a filter from an external program?
If so what sub/function do you call?
I've tried the ConfigDlgProc but Visual Basic says 'Can't find DLL entry point'
my vb  code
| CODE | Private Type FilterData
show As Boolean
smoothMotionMap As Boolean
useMotionMap As Boolean
deinterlaceThreshold As Integer
lineDetect As Integer
motionThreshold As Integer
prevFrameLuma As Integer
ixelbackUp As String
pixelChanges As String
End Type
Private Declare Function ConfigDlgProc Lib "D:\Visual Basic Files\DeinterlaceMAP.vdf" (hdlg As Long, msg As Integer, wParam As FilterData, lParam As FilterData) As Boolean
'The C code def
'BOOL CALLBACK ConfigDlgProc(HWND hdlg, UINT msg, WPARAM wParam, LPARAM lParam)

Interesting idea, but it can't be done.
Filter modules export two functions, "VirtualdubFilterModuleInit2" and "VirtualdubFilterModuleDeinit." Both of these functions receive pointers to other functions within VirtualDub itself. If you are not VirtualDub, you can't supply the filter with these pointers.
But even if you could supply some pointers for the filter to call, Visual Basic can't call the filter's exported functions anyway because they use the C calling convention (VB doesn't support this).

May the FOURCC be with you... |

Thanks for the information
Maybe I could write an C dll that called the filter and then use the dll I wrote in VB
