Does you code actually look for a setting in the app.config file? What does that code look like?
|
|
|
|
|
The code in the application looks like the following:
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
frmMain.GlobalForm = Me
Dim strUserName As String = ConfigurationManager.AppSettings("NameofUser")
If strUserName = "ANN" Then
Dim strDirectoryPath As String = ConfigurationManager.AppSettings("File_directory_path")
If Not (Directory.Exists(strDirectoryPath)) Then
Application.Exit()
Exit Sub
End If
Else
Dim strDirectoryPath2 As String = ConfigurationManager.AppSettings("File_directory_path_KARON")
If Not (Directory.Exists(strDirectoryPath2)) Then
Application.Exit()
Exit Sub
End If
End If
The code in the app.config file looks like:
<?xml version="1.0"?>
<configuration>
<system.diagnostics>
<sources>
<!-- This section defines the logging configuration for My.Application.Log -->
<source name="DefaultSource" switchName="DefaultSwitch">
<listeners>
<add name="FileLog"/>
<!-- Uncomment the below section to write to the Application Event Log -->
<!--<add name="EventLog"/>-->
</listeners>
</source>
</sources>
<switches>
<add name="DefaultSwitch" value="Information"/>
</switches>
<sharedListeners>
<add name="FileLog" type="Microsoft.VisualBasic.Logging.FileLogTraceListener, Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" initializeData="FileLogWriter"/>
<!-- Uncomment the below section and replace APPLICATION_NAME with the name of your application to write to the Application Event Log -->
<!--<add name="EventLog" type="System.Diagnostics.EventLogTraceListener" initializeData="APPLICATION_NAME"/> -->
</sharedListeners>
</system.diagnostics>
<startup><supportedRuntime version="v2.0.50727"/>
</startup>
<appSettings>
<add key="NameofUser" value="ANN"/>
</appSettings>
</configuration>

It's not entirely clear what you're doing or what you expect.
Any setting you want can be placed into the app.config appSettings section and loaded with an appropriate call to ConfigurationManager.AppSettings("name") to get the setting of that name.
The app.config file is NEVER compiled into the application. It must reside in the same folder as the .EXE that is loading it.
In your code snippets, you try to get settings called "File_directory_path" and "File_directory_path_KARON", but these never show up in the app.config file so the values returned for those names will be null, not any string value.
When you change the setting in app.config, the new setting will be loaded on the next call to retrieve that setting in the code.

I did not show the values in app.config file for "File_directory_path" and "File_directory_path_KARON",
since I just wanted to show you an example. I know what the code is supposed to do by it is not working. The app.config file will not let me change the values outside of the application. The file is locked.
Once a user signs on to their computer, I try to change the values in the app.config file. The permissions are locked. The network people say that the user and I have all the rights (permissions) that are needed. I open up the app.config file in notepad in the users computer and the values are not saved. Do you know what else could be wrong so I can not change the permissions. I install the application using the old setup and deployment project that is in visual studio.

If the app isn't running, the only other common possibility is that the executable (and the config file) are under Program Files, which is READ ONLY to everyone on the machine, except admins. If you're an admin on the machine and can't understand why when YOU try to save the changes to app.config, it's because you have to run Notepad as an administrator. (Search for notepad.exe, right-click it, pick Run as administrator..)
If you're putting settings in a file that needs to be written to by your app or even Notepad, put them in a file under C:\ProgramData\appName\...
You can then modify the code to load the settings from that path instead of from under Program Files. See this[^] for examples.

In the bin directory, there is a runtime config file called 'programname.exe.config'. I do not deploy this when I deploy the application. Do I need to include the 'programname.exe.config' as part of the deployment? if so, when the application is only a user's computer, would I change the 'programname.exe.config' file and/or the app.config file in notepad?

I'm trying to figure out how to make the Ascending / Descending extension in an Order By statement in a Linq query conditional based upon a menu selection. Here's the query:
Dim fileItem = From files In itemList
Where files.Tag(0) = "file"
Order By files.SubItems.Item(indx).Text
Select files
(itemList is a List of listviewitems)
Any advice is appreciated.
Sometimes the true reward for completing a task is not the money, but instead the satisfaction of a job well done. But it's usually the money.

Not exactly what I was hunting since the menu item isn't a part of the collection. But no big thing. I finally just added code to reverse the collection if I needed it sorted in descending order.

Simple:
Dim fileItem = From files In itemList
Where files.Tag(0) = "file"
Select files
If shouldSortDescending Then
fileItem = From files In fileItem
Order By files.SubItems.Item(indx).Text Descending
Select files
Else
fileItem = From files In fileItem
Order By files.SubItems.Item(indx).Text
Select files
End If Or, using "method syntax":
Dim fileItem = itemList.Where(Function (files) files.Tag(0) = "file")
If shouldSortDescending Then
fileItem = fileItem.OrderByDescending(Function (files) files.SubItems.Item(indx).Text)
Else
fileItem = fileItem.OrderBy(Function (files) files.SubItems.Item(indx).Text)
End If

You could always create your own extension method. 
Module SortingExtensions
<Extension()>
Public Function OrderBy(Of TElement, TKey)(
ByVal source As IEnumerable(Of TElement),
ByVal selector As Func(Of TElement, TKey),
ByVal sortDescending As Boolean) _
As IOrderedEnumerable(Of TElement)
Return If(sortDescending, source.OrderByDescending(selector), source.OrderBy(selector))
End Function
<Extension()>
Public Function ThenBy(Of TElement, TKey)(
ByVal source As IOrderedEnumerable(Of TElement),
ByVal selector As Func(Of TElement, TKey),
ByVal sortDescending As Boolean) _
As IOrderedEnumerable(Of TElement)
Return If(sortDescending, source.ThenByDescending(selector), source.ThenBy(selector))
End Function
End Module
...
Dim fileItem = itemList.Where(Function (files) files.Tag(0) = "file").OrderBy(Function (files) files.SubItems.Item(indx).Text, shouldSortDescending)
There's no option to extend the query syntax though.

Thanks Richard. I ended up writing something similar to the "Simple" version. I've been shamelessly flip-flopping around on this thing for a month - good thing it's just for me and not a customer  .

I have an HTML file that I'm loading into a WebBrowser control via .Navigate(myfileURI) which works fine.
In my application I'm trapping Javascript errors in order to handle them myself via the code on this web page:
https://msdn.microsoft.com/en-us/library/system.windows.forms.htmlwindow.error%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396
This seems to work fine until I tweak the compatibility mode in the html file. For example, using the meta tag:
<meta http-equiv="X-UA-Compatible" content="IE=8">
or even no such tag at all works fine. However when I use the meta tag:
<meta http-equiv="X-UA-Compatible" content="IE=10">
or
<meta http-equiv="X-UA-Compatible" content="IE=edge">
the code to trap Javascript errors no longer works.
I'd really like to know why?
I'd prefer to use IE10 or edge for access to better Javascript functionality.
Here's the code I used in a simple Visual Basic Form and WebBrowser control as well as a simple "test.html" file below it:
(Note: the "a.args" line in the html file is suppose to deliberately throw an error)
Thanks in advance,
Jeff

Task:
Two windows have been opened.
1. Outlook
2. the Windows Explorer
If you now take a mail from the Outlokk Inbox with the left mouse button, pull it over to the Windows Explorer and release it there over a folder then the mail is stored there as a file under the name e.g. Request.msg
Request is the subject of the mail.
Now the second window should be the application to be developed.
There should be a textbox above in which the mail is dropped.
So far I have the following code:
Private Sub TextBox1_DragOver(ByVal sender As Object, ByVal e As DragEventArgs) Handles TextBox1.DragOver
'erlaubte DropEffects festlegen
If e.Data.GetDataPresent("FileGroupDescriptor") Or e.Data.GetDataPresent("FileDropList") Then
e.Effect = DragDropEffects.All
Else
e.Effect = DragDropEffects.None
End If
End Sub
Private Sub TextBox1_DragDrop(ByVal sender As Object, ByVal e As DragEventArgs) Handles TextBox1.DragDrop
' Drop durchführen
Dim ioStream1 As IO.Stream = DirectCast(e.Data.GetData("FileGroupDescriptor"), IO.Stream)
Dim Array1(CInt(ioStream1.Length)) As Byte 'Array anlegen
ioStream1.Read(Array1, 0, Array1.Length) 'Array füllen
'Build the FileName from the FileGroupDescriptor block.
Dim sFileName As New System.Text.StringBuilder("")
Dim i As Integer = 76 'The FileName starts at position 76 in the FileGroupDescriptor.
While Array1(i) <> 0
sFileName.Append(Convert.ToChar(Array1(i)))
i += 1
End While
ioStream1.Close()
MessageBox.Show(sFileName.ToString) 'der Dateiname wird richtig angezeigt
'Mail Inhalt auslesen
Dim ioStream2 As IO.Stream = DirectCast(e.Data.GetData("FileDropList", True), IO.Stream)
Dim Array2(CInt(ioStream2.Length)) As Byte 'Array anlegen
ioStream2.Read(Array2, 0, Array2.Length) 'Array füllen
End Sub
The file name is displayed correctly but ioStream2 is allways nothing
"FileDropList" is probably the wrong parameter. But which one is the right one?
Microsoft.Office.Interop or
System.Runtime.InteropServices and
Dim objOL As New Microsoft.Office.Interop.Outlook.Application
may not be used because an error message is displayed on the Exchange Server.
How can I read the content of the mail?
Thanks in advance

Thanks for the answer!
But System.Runtime.InteropServices; is used.
This causes error messages on the Exchange Server.

Office Interop is blocked on a server. So, why would you want to create a UI for the server? And might what you want not be easier by writing an outlook-plugin?

You should be storing all of your data in a suitable data stricture, NOT directly in the DGV. Once you have the data in a data structure, you set the DataSource of the DGV to the data structure. It also makes it MUCH easier to save the data structure to a file than the DGV.
You data structure can be a List<t>, a DataSet, a DataTable, some custom collection, ... whatever. Just don't use the DGV to "store" data. Controls are there to show a visual representation of data and edit that data, not to store it.
