VB6 Byte array in VB.NET

Question

I have some image comparison DLL, and documentation for VB6, but I want to use it in ASP.NET/VB.NET

In documentation is stated following:

iDLLoadImage

Description : Load the captured image (in raw format), preparing for face detection.

Declaration : iDLLoadImage (pByte As Byte, iWidth As Long, iHeight As Long, iColor As Long)

Parameters : pByte : byte array which stored the (raw) captured image (in) iWidth : for setting raw image width (in) iHeight : for setting raw image height (in) iColor : 1 for Gray image, 3 for RGB image (in)

Return Values : 0 : Successful -1 : This library is not enabled. -2 : pByte is NULL. -3 : Failed to initialize internal parameters

But, when I try to pass it byte array in VB.NET it says it expects byte .

Is there any solution for this?

Try these things:

1. A Dabblernl said, try using image(0) as a parameter. Since it is byref, it may pass the memory location and from there process the entire array.

2. You may be able to declare the function as an alias, and change the first parameter to pByte As Byte() .
