GetMappedFileName VB.NET RRS feed

  • Question

  • Hi All,
    I am trying to convert a code from C to <acronym title="Visual Basic">VB</acronym>.NET.

    I have a function with the following declaration -

    Declare Function GetMappedFileName Lib "psapi" (ByVal hProcess As IntPtr, ByVal lpv As IntPtr, <Out()> ByRef lpFilename As String, ByVal nSize As Long) As Long

    I am calling the function as follows -

    GetMappedFileName(handle, Address, MappedFile, Marshal.SizeOf(MappedFile))

    where MappedFile is declared as -

    Dim MappedFile As String = ""
    MappedFile does not return anything. Any help will be appreciated.

  • Hi,

    You can try to call the method as below:

     GetMappedFileName(handle, Address, ref MappedFile, Marshal.SizeOf(MappedFile))

    In this way, retrieve value will be cast to MappedFile object.

    I hope this can help you resolve your problem.
