Overwrite contents of file in VB - vba

Question

I am reading a list of files and come accross updated versions along the way. In my loop I am checking if the file already exists and trying to remove it, so that I can create the newer version again:
objFs = CreateObject("Scripting.FileSystemObject")
If (objFs.FileExists(location & "\" & fileName & ".xml")) Then
System.IO.File.Delete(location & "\" & fileName & ".xml")
End If
objTextStream = objFs.CreateTextFile(location & "\" & fileName & ".xml", True)
objTextStream.Write(System.Text.Encoding.UTF8.GetString(recordXml))
Ideally I would rather just open the file if it already exists and overwrite the contents, but so far my attempts have been in vein.
location is a user defined path, e.g. c://
recordXML is a retrieved value from the database
The main error I keep getting is
Additional information: Argument 'Prompt' cannot be converted to type 'String'.
Which seems to mean that the file is either not there to delete, or it is already there when I am trying to create it. The delete may not be working as it should, it may be that the file is not deleted in time to recreate it?..
That's my thoughts anyway.

Found this code at http://www.mrexcel.com/forum/excel-questions/325574-visual-basic-applications-check-if-folder-file-exists-create-them-if-not.html for creating a new file (unless one already exists) and then opening it (existing or new). Once you open, you can just do a Sheets(
NAMEOFSHEET").Cells.Clearto clear the cells and then paste your data.
Sub btncontinue_Click()
Dim myFile As String, myFolder As String
myFolder = "C:\TimeCards"
myFile = myFolder & "\timecards.xls"
If Not IsFolderExixts(myFolder) Then
CreateObject("Scripting.FileSystemObject").CreateFolder myFolder
End If
If Not IsFileExists(myFile) Then
MsgBox "No such file in the folder"
Exit Sub
End If
Set wb = Workbooks.Open(myFile)
' Your code here
End Sub
Function IsFolderExists(txt As String) As Boolean
IsFolderExists = _
Createobject("Scripting.FileSystemObject").FolderExists(txt)
End Function
Function IsFileExists(txt As String) As Boolean
IsFileExists = _
CreateObject("Scripting.FilesystemObject").FileExists(txt)
End Function

You could try this, it should work in VB, VBA and VBScript.
objFs = CreateObject("Scripting.FileSystemObject")
If objFs.FileExists(location & "\" & fileName & ".xml") Then Kill(location & "\" & fileName & ".xml")
Open location & "\" & fileName & ".xml" For Output As #1
Print #1, recordXml
Close #1

Try to use FSO to delete the file. Also the objTextStream needs to be set because it is object.
Sub AnySub()
Dim objFs As FileSystemObject
Set objFs = CreateObject("Scripting.FileSystemObject")
If (objFs.FileExists(Location & "\" & Filename & ".xml")) Then
objFs.DeleteFile Location & "\" & Filename & ".xml"
End If
Set objTextStream = objFs.CreateTextFile(Location & "\" & Filename & ".xml", True)
objTextStream.Write recordXml
End Sub
I m not sure the .write method work with UTF8.
I m using this function:
Sub File_WriteToUTF8(File_Path As String, s_Content As String)
On Error GoTo ende
Dim LineStream As Object
Set LineStream = CreateObject("ADODB.Stream")
With LineStream
.Type = 2
.Mode = 3
.Charset = "utf-8"
.Open
.WriteTEXT s_Content
.SaveToFile File_Path, 2
ende:
.Close
End With
End Sub
So instead of
objTextStream.Write recordXml
it would be
File_WriteToUTF8 Location & "\" & Filename & ".xml", recordXml
