Function Main()
                Dim sMsg as string

                sMsg = MoveFile(DTSGlobalVariables("LoadFileName").Value)
                if (sMsg) = "" then
                                Main = DTSTaskExecResult_Success
                else
                                Main = DTSTaskExecResult_Failure
                end if
End Function
Function MoveFile(ByVal fileName)

You need to manually rewrite the code.

This code has problems. It should be simplified: creating objects in arcane and roundabout ways, too many lines of code to do a simple operation, etc.

MoveFile is also a Win32 API kernel32 function. It returns a boolean value . Looks like whoever wrote this VB MoveFile function is trying to parrot the MoveFile API.

If you want to use the MoveFile API, then declare it properly first. Private Declare Function MoveFile lib "kernel32" Alias "MoveFileA" (ByVal lpExistingFileName as String, ByVal lpNewFileName as String) as long All it does is rename the file or folder name. It returns 0, if it fails. Otherwise, it returns a nonzero value if successful.

It's pretty sad when you can write 6 or 7 lines of code to do the same thing using Win32 APIs to replace about 40 lines of VB6 code. This is a prime example of violating the programmer's paradigm of KISS: Keep It Simple Stupid. Visual Basic was designed to make things simple, not complicated.

And you're requesting .NET information on a VB6 forum. You are in the wrong place.
Whereever you got this code, it is more complicated than it should be. If you wrote this code, you obviously don't need any help. Or you're just bored and looking for a good laugh.

hkdani: Actually i dont know vb as well as vb.net but i got this work. And m requesting on vb6 forum bz to change the code first u shud know vb6 rght then only u can convert it.

Then you need to learn the language first.
Go and read books.

Ok, this is the .NET version. In the future post .NET questions on the .NET forum.

To move a directory and rename it use the MoveDirectory method: specify the source and target directories.

In general, just post what you wish to accomplish and ask for instructions on the appropriate topic in the appropriate forum.

My.Computer.FileSystem.MoveDirectory("C:\MyDir1", _
    "C:\MyDir2", True)
