The following code does everything I want: pulls email, saves attachments, extracts files EXCEPT save the original email to the folder fDest. I seem unable to see the solution.

This seems to be the problematic line as it won't save the email: "mi.SaveAs fDest2, olMSG"

Sub SaveAttachments()
    Dim ol As Outlook.Application
    Dim ns As Outlook.Namespace
    Dim fol As Outlook.Folder
    Dim i As Object
    Dim mi As Outlook.MailItem
    Dim at As Outlook.Attachment
    Dim Inbox As MAPIFolder
    Dim strDate As String
    Dim oApp As Object
    Dim fDest As Variant
    Dim j As Variant
    Dim sh As String
    Dim FileDialog As FileDialog
    Dim Tracker As Workbook
    Dim fSheet As Sheets
    Dim LastRow As Long
    Dim strFilePath
    Dim fTracker As Workbook
               
    strDate = InputBox("Enter Date in format dd-Mmm-yyyy", "User Date", Format(Now(), "dd-Mmm-yyyy"))
    strFilePath = "\\namdfs\CARDS\MWD\GROUPS\GCM_NAM\2021\05 May\"
    fTrackerName = "Inquiry.Tracker.SWPA.Violations.May.2021.xlsx" '

    On Error Resume Next
        Set fTracker = Workbooks(fTrackerName)
        'If Err Then Set fTracker = Workbooks.Open(strFilePath & fTrackerName)
    On Error GoTo 0
        'Windows(fTrackerName).Activate
      
    Set ol = New Outlook.Application
    Set ns = ol.GetNamespace("MAPI")
    Set fol = ns.Folders("GCMNamLogs").Folders("Inbox")
        
    fDest = "C:\Users\jb76991\Desktop\Violations_Emails\"
    fUser = UCase(Environ("username")) & ":" & Chr(10) & Now()
        
    For Each i In fol.Items.Restrict("@SQL=urn:schemas:httpmail:subject LIKE '%" & strDate & "%'")
        'Debug.Print fDest & i & ".msg"
        If i.Class = olMail Then
            Set mi = i
            fDest2 = fDest & mi.Subject & ".msg"
            mi.SaveAs fDest2, olMSG
            For Each at In mi.Attachments
                'do something with attachments but i've commented it out
            Next at
        End If
    Next i
    MsgBox ("Completed")
    
End Sub

Can anyone tell me how to save the original emails that are being filtered?

Meson/Ninja provide an easy method to run a script at install time.
For example, this line will tell Meson to run the glib-compile-schemas command to compile the GSettings on Linux (system configuration options).

meson.add_install_script('glib-compile-schemas', schemas_dir)
(this command will be automatically run when the user executes ninja install)

How can I tell Meson to run a custom command at uninstall?
In this specific case I would like to delete (or at least reset to default) the key-value pairs in GSettings. To reset them, I have found that the command is gsettings reset-recursively <path> (successfully tested in terminal).

I am trying to parse many XML test results files and get the necessary data like testcase name, test result, failure message etc to an excel format. I decided to go with Python.

My XML file is a huge file and the format is as follows. The cases which failed has a message, & and the passed ones only has . My requirement is to create an excel with testcasename, test status(pass/fail), test failure message.

I have come up with the following code. Please bear if there are any basic mistakes as I am very new to this. With this code I can retrieve test case name, class name but I am unable to pick the failure message, system-out and system-err. Though these tags are also part of testcase tag, I am not able to fetch it. Can someone help me through this? Thanks! With only testcase name and class name, I am able to write to an excel.

## Parsing XML files ###

What I'm trying to do:

I have a WPF app, linked to a SQL-server. I am using the MVVM-light package (I do actually have Prism.Core installed, but I'm not sure if I'm using it or not.... new to MVVM).

There's a DataGrid, bound to an ObservableCollection. I have been trying to implement the PropertyChangedEventHandler, but I can't seem to get it to work.

I have a Delete button bound, and I am able to remove rows, but when I re-open the form, the changes does not carry over.

I tried to change the binding-mode for the DataGrid from OneWay to TwoWay. With OneWay, the changes does not carry over when I re-open the form. With TwoWay, I get this error message when opening the child form (which contains the DataGrid):

System.InvalidOperationException: 'A TwoWay or OneWayToSource binding cannot work on the read->only property 'licenseHolders' of type 'Ridel.Hub.ViewModel.LicenseHoldersViewModel'.'

So, If I then add a set; to my public ObservableCollection<LicenseHolders> licenseHolders { get; }, the program runs, but the previous problem persists, like it did when there was a OneWay mode configuration on the DataGrid.

What do I need to do to get this to work without communicating directly with the Sql-server, which would defy the whole point of using this methodology in the first place?

Collapsing toolbar layout and the recycler view should work together while swiping but working separately. suggest to me what to do! given below are my code and resulting gif part of my project.

Final result

I wanted to create a custom Alertdialog Layout with a dropdown list and a few other things. I'm using Kotlin and I'm pretty new to it Currently I'm stuck at the dropdown list as it doesn't show anything

Here is the Layout.xml:

    <?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/backButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="20dp"
        android:layout_marginTop="20dp"
        android:text="Zurück"
        app:icon="@drawable/ic_baseline_arrow_back_24"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <Spinner
        android:id="@+id/pizzaSelection"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginTop="100dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

</androidx.constraintlayout.widget.ConstraintLayout>

And here is how I call up the dialog in my activity:

   private fun showPizzaDialog(){
        val pizzaDialogBuilder = AlertDialog.Builder(this)
        pizzaDialogBuilder.setView(R.layout.pizza_alertdialog)
        
        val pizzaDropdown = findViewById<Spinner>(R.id.pizzaSelection)
        val pizzaTypes = resources.getStringArray(R.array.pizzaTypes)

        if (pizzaDropdown != null) {
            val adapter = ArrayAdapter(this,
                android.R.layout.simple_spinner_item, pizzaTypes)
            pizzaDropdown.adapter = adapter
        }
        
        pizzaDialogBuilder.show()

    }

The Items are currently hardcoded in the strings.xml resource file as a string-array.

The AlertDialog shows up and i can see and click on the arrow for the dropdown menu, but when I click on it nothing happens.

im trying to get Highscores from a File and display them in a RecyclerView. But im getting the following Error:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference
        at com.example.ausbaustufe1.CustomAdapter.onBindViewHolder(CustomAdapter.java:46)
        at com.example.ausbaustufe1.CustomAdapter.onBindViewHolder(CustomAdapter.java:16)

I know that my scoreItems in

CustomAdapter adapter = new CustomAdapter(scoreItems); 

arent empty. I dont know what i am doing wrong. I´m new in the Android World :)

Thanks for helping.

My files: score_activity.java

public class score_activty extends AppCompatActivity {
    ArrayList<ScoreItem> scoreItems;
    FileIOScores io = new FileIOScores(this);
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_score_activty);
        RecyclerView rvItems = findViewById(R.id.recview);
        scoreItems = io.readScores("file1.txt");
        Log.v("mytag",scoreItems.toString());
        CustomAdapter adapter = new CustomAdapter(scoreItems);
        Log.v("mytag",String.valueOf(adapter.getItemCount()));
        rvItems.setLayoutManager(new LinearLayoutManager(this));
        rvItems.setAdapter(adapter);

I'm new to android studio and i'm not sure what was going on with it. How can I solve this error?

In the logcat, it mentioned that I required a view for recycler_food_list which apparently I had already coded into the foodlistfragment.java.

I need to implement the below layout for my RecyclerView Items (The picture represents two rows):

This is my XML file:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/theme_primary_color">

    <View
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:background="@drawable/half_circle"
        android:translationZ="3dp"
        app:layout_constraintBottom_toTopOf="@id/cvTop"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="@id/cvTop" />

    <androidx.cardview.widget.CardView
        android:id="@+id/cvTop"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="2dp"
        android:layout_marginEnd="8dp"
        app:cardCornerRadius="@dimen/card_view_corner"
        app:layout_constraintTop_toTopOf="parent">

    </androidx.cardview.widget.CardView>

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fabCall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_call"
        app:backgroundTint="@color/fab_green"
        app:fabSize="mini"
        app:layout_constraintBottom_toBottomOf="@+id/cvTop"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/cvTop" />

</androidx.constraintlayout.widget.ConstraintLayout>

I tried to set negative margins to root ConstraintLayout but the second item went to top of the first one, but I need the first item to be on top of the second one.

I have tried tried a few solutions given here but none seems to work for me. This is what I have in my colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#fcfdfb</color>
    <color name="colorPrimaryDark">#fff</color>
    <color name="colorPrimaryLight">#333</color>
    <color name="colorPrimaryText">#333</color>
    <color name="colorAccent">#000000</color>
    <color name="white">#ffffff</color>
    <color name="black">#000000</color>
</resources>

And this is what I have in styles.xml

<resources xmlns:tools="http://schemas.android.com/tools">
    <style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowBackground">@drawable/background_splash</item>
    <item name="android:windowActionBar">false</item>
</style>
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowBackground">@drawable/background_splash</item>
    <item name="android:windowActionBar">false</item>
</style>
<style name="ProDialogue" parent="@android:style/Theme.Dialog">
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowBackground">@color/colorPrimary</item>
    <item name="android:textColor">@color/black</item>
</style>
<style name="TransparentToolbar" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:windowActionBarOverlay">true</item>
    <item name="windowActionBarOverlay">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

I just need the Statusbar text/icons to be black because I have the background as white to match the content. As a beginner, I am sure that I've messed it up somewhere but hopefully someone will guide me on this. Btw, my minSdkVersion is 21.
