copying files

[masterhoulahan]

Hi i was wondering if it would be possible to make a code which was similar to the dos xcopy command like the /D:m-d-y function which the date and location could be inputted by a text boxes ive looked on the forum but could only see copying functions.
thanks in advance

what does the dos xcopy command do?

[masterhoulahan]

Xcopy is a powerful version of the copy command with additional features; has the capability of moving files, directories, and even whole drives from one location to another.

/D:m-d-y Copies files changed on or after the specified date. If no date is given, copies only those files whose source time is newer than the destination time.

InvalidOperationException was unhandled
Process must exit before requested information can be determined.

thanks

Thats because the code is actually waiting 15 seconds for the process to exit, then it tries to get the ExitCode of the process. However if the process hasnt exited after the 15 second wait, that exception will occur.
A way better thing to do is to add a handle for the process' Exited event, and perform all code that needs to be done after the process has exited in that event handler instead.

You don't need to go through all the hassles of trying to run the cmd process from .NET. All the functionality of XCOPY can be reproduced using .NET objects

Private _fileDate As DateTime

    Private Sub btnCopyFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCopyFiles.Click
        
        Dim sOriginDir as String = txtOriginDir.Text
        Dim sDestDir as String = txtDestDir.Text

        Dim fileCol As FileInfo() = My.Computer.FileSystem.GetDirectoryInfo(sOriginDir).GetFiles()

        _fileDate = txtFileDate.Text

        Dim filesToCopy As FileInfo() = Array.FindAll(fileCol, AddressOf FindFile)

        For Each fi As FileInfo In filesToCopy
            fi.CopyTo(sDestDir + "\" + fi.Name, True)
        Next

    End Sub

    Private Function FindFile(ByVal pFile As FileInfo) As Boolean

        If pFile.LastWriteTime > _fileDate Then
            Return True
        Else
            Return False
        End If

    End Function

That will grab any files in a given directory that have been modified after a given date and copy them to another directory. You can also customize it as you see fit, rather than trying to pass a bunch of stuff intoa command line program.

that is a much better way thanks! only one problem though

FileInfo() is not declared

sorry for the hassle

Either use the full path: System.IO.FileInfo, or Import the System.IO namespace.
