  Hi, I had an application written using vb 6.0 i converted it into vb.net 3.5 framework. In this application i use to pass a structre by ref to dll which is written in vc ++ (unmanaged code). when i run the program i use to get the following error

  Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

  A first chance exception of type 'System.AccessViolationException' occurred in ABC.exe

  now here is a code snippet how i am calling this function

  Public Declare Function RunCommSpec1 Lib "XYZ.dll" Alias "CDE" (ByRef ASD As HTY, ByRef dataStruct As RET) As Byte

  the DLL is in bin directory

  I can not understand why i am getting this error. i worked almost a week for this error.

  Thanks
