[2005] Where is my problem

[Bongo]

Greetings,

When I try to run this code i get most time a exception in the part
Catch exc As Exception
It is a IOException
The Process can not access the file D:\views\pledlm_view\applications\ktr\source\KTR Client\KTR Client\bin\Release\KTR Client.exe.config because another process is using it.

Background:
1. The app = not MutliThreating
2. I use the routine to add a new value in to the App.config

For easier understanding i posted the whole class as zip to the thread

Private Function LoadConfigSource() As String
 
        Dim dllPath As String = System.Reflection.Assembly.GetExecutingAssembly.Location
        Dim filename As String
 
#If DEBUG Then
        '--> if debug app.config file is not in bin folder
        Dim strTemp As String = Path.GetDirectoryName(dllPath)
        strTemp = strTemp.Substring(1, strTemp.Length - 1)
        strTemp = strTemp.Substring(1, strTemp.LastIndexOf("\bin\"))
        filename = strTemp & "app.config"
#Else
        '--> get the name of the calling assembly (in the testcase TestConfigProvider) and built the path of the config file in release mode
        filename = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly.Location) & "\" & System.Reflection.Assembly.GetEntryAssembly.GetName.Name.ToString & ".exe.config"
#End If
        configSource = New XmlDocument
 
        Dim cstream As Stream
 
        Try
            cstream = File.OpenRead(filename)
            configSource.Load(cstream)
 
        Catch ex As FileNotFoundException
            Throw ex
        Catch exc As Exception
            Throw exc
        Finally
            If Not cstream Is Nothing Then cstream.Close()
        End Try
 
        Return filename
 
    End Function

Thanks for any help

You shouldn't be opening the config file durectly anyway. Access it via the System.Configuration namespace. Look at the ConfigurationManager.OpenExeConfiguration method.

@jmcilhinney:

ok I am using now (which is match more easier could remove the whol.e class)the following line to get a value from the appsettings

cstMonthView.BColor1 = ConfigurationManager.AppSettings.Get("ABC")

but and sorry jmcilhinney when i do the following line of code

ConfigurationManager.AppSettings.Set("ABC", "Red")

the value is only temporary availible.

After starting the app again the Value "Red" is not in the app.config
So it seams to me the value are never writen to the key in the app.config

For simplicity i replaced here the org code with dummy Values and keys.

The original Lines would be for get

Color.FromName(ConfigurationManager.AppSettings.Get(My.Resources.KonfigKalenderBackColor1))

and for set

cstMonthView.BColor1 = Color.FromName(ConfigurationManager.AppSettings.Get(My.Resources.KonfigKalenderBackColor1))
