Help Required Upgrading VB6 project to VB Net

Question

i have been trying to upgrade the VB6 project that can be found at http://www.vbaccelerator.com/home/VB/Code/vbMedia/Audio/WAV_File_Viewer/article.asp I have managed to get the majority done, using a combination of the upgrade facility and some programming of my own. I have now unfortantly got stuck with the following line of code: copymemory(VarPtrArray(iWav), VarPtr(tSA), 4) (copymemory being the standard API call to RtlMOveMemory in kernel32) The problem i have is the VarPtr command, and to some extent the VarPtrArray command. I need a solution for VBnet. Background information: tSA is variable of the following structure: _ Private Structure SAFEARRAYBOUND Dim cElements As Integer Dim lLbound As Integer End Structure _ Private Structure SAFEARRAY2D Dim cDims As Short Dim fFeatures As Short Dim cbElements As Integer Dim cLocks As Integer Dim pvData As Integer Dim BoundsR() As SAFEARRAYBOUND Public Sub Init() ReDim BoundsR(1) End Sub End Structure and is created just before the copymemory line by Dim tSA As SAFEARRAY2D tSA.Init() and propulated with With tSA .cbElements = 2 .cDims = 2 .BoundsR(0).lLbound = 0 .BoundsR(0).cElements = m_cWAVRead.ReadbufferSize .BoundsR(1).lLbound = 0 .BoundsR(1).cElements = 2 End With iwav is created in the following method Dim iWav() As Short If you need any more information please email me at [email protected] (please remove the nospam) or reply to the post. I have both the orignal VB6 project, the VBnet project created using the upgrade wizard and my own semi working version. Thanks for any help provided Adrian
