Question

I am trying to do an automated xml export from an access database using C# and OLE. Everything is working perfectly except that the startup form is shown and won’t close without user intervention.

Here’s what I am doing so far:

objAccess = CreateObject('Access.Application'); objAccess.OpenCurrentDatabase('C:\\MYDB.mdb', true); //true = open in exclusive mode objAccess.ExportXML(0, 'TestTable', 'c:\\test.xml'); objAccess.CloseCurrentDatabase(); objAccess.Quit();

As far as I know the only way is to use the /nostartup switch on msaccess.exe

So you have to use shell command to get the access object

I have a function that opens a database and returns the object (This is VBA code which you will have to convert to C#)

Private Function OpenDatabaseWithShell(pDatabaseFullPath As String) As Access.Application  Dim AccObj As Access.Application      On Error GoTo ErrorHandler      Set OpenDatabaseWithShell = Nothing      Dim cmd As String      On Error Resume Next      ' basically build full msaccess.exe path and append database name and command switches     cmd = SysCmd(acSysCmdAccessDir) & 'MSAccess.exe ''' & psDatabaseFullPath & ''''     cmd = cmd & ' /nostartup /excl'      'start ms access with shell     Shell PathName:=cmd      Do 'Wait for shelled process to finish.       Err = 0       Set AccObj = GetObject(pDatabaseFullPath)     Loop While Err <> 0      On Error GoTo ErrorHandler      'return access object     Set OpenDatabaseWithShell = AccObj  NormalExit:     Exit Function  ErrorHandler:     'error logging here     Exit Function  End Function 

EDIT: Here’s a link to some VB.NET code that does a similar thing. Scroll down to ‘Create the Complete Sample Visual Basic .NET Project’ and look for the ‘ShellGetDB’ function
