I'm working on a wpf app. visual studio 2022
I have the following code in a file for testing and have set a button click event to run WriteWorkOrderList(). nothing gets passed to it: there are no other methods or anything:
private List<Models.WorkOrder> _workOrderList = new List<Models.WorkOrder>();
public List<Models.WorkOrder> WorkOrderList
{
get
{
return _workOrderList;
}
set
{
if (_workOrderList != value)
{
_workOrderList = value;
NotifyPropertyChanged();
}
}
}
private Models.WorkOrder _currentWorkOrder = new Models.WorkOrder();
public Models.WorkOrder CurrentWorkorder
{
get
{
return _currentWorkOrder;
}
set
{
if (_currentWorkOrder != value)
{
_currentWorkOrder = value;
NotifyPropertyChanged();
}
}
}
public void WriteWorkOrderList()
{
CurrentWorkorder.Customer.Name = "Billy";
WorkOrderList.Add(CurrentWorkorder);
}
I placed a Breakpoint at the beginning of the WriteWorkOrderList()
method
I'll let it continue the first time. and get one record in
WorkOrderList with Customer.Name=Billy.
the second time I click the
button and get to the breakpoint I will change the
CurrentWorkOrder.Customer.Name= "joe".
I'll Step through the code
as soon as the line CurrentWorkorder.Customer.Name = "Billy"; gets processed the record in WorkOrderList updates to the new name
I can't figure out how they are connecting to each other. All I'm trying to do is add a new WorkOrder to the Workorderlist but I haven't Even gotten that far

I am trying to get the current location and display it on a OSMdroid map inside an Android application. But I get no location and a Runnable that is supposed to be called the first time the location is found is never called.
I have tried different providers, permissions are all enabled and GPS location, too.
private void getCurrentLocation() {
GpsMyLocationProvider provider = new GpsMyLocationProvider(this);
provider.addLocationSource(LocationManager.GPS_PROVIDER);
provider.addLocationSource(LocationManager.NETWORK_PROVIDER);
myLocationOverlay = new MyLocationNewOverlay(provider, mMapView);
myLocationOverlay.enableMyLocation();
myLocationOverlay.setDrawAccuracyEnabled(true);
myLocationOverlay.runOnFirstFix(new Runnable() {
public void run() {
// never reaches this point
Timber.i("runOnFirstFix");
}
});
mMapView.getOverlays().add(myLocationOverlay);
if (myLocationOverlay.getMyLocation() == null) {
// this shows up
Timber.i("Location not retrieved");
}
}
I understand that the location might not be found as soon as the overlay is added, but I don't understand why the Runnable doesn't work
I have a Modal class, when this modal is opened, it shows a panel asking the user if the user wants to proceed with the operation. If the user selects Yes the request is sent to the DB, which takes some time, during this time the first panel should be replaced by the second (which displays a spinner). This indeed happens if we do not use the third panel. Although I want to replace the second panel by the third panel in order to inform the user if the operation was successful or not (which depends of the message object,if it is null or have an error message).
So when I use addNewPanel(panel3, target) I never see panel2. I put a thread.sleep(5000) instruction after addNewPanel(panel2, target) and even so, this panel didn't appeared, I only get the initial and panel3 in the end.
If I do not use panel3 I see panel2.
Does anyone have an idea why is this happening?
Below I have the code of the Modal class
public class DetailsModal2 extends Modal<IModel<UserDomain>>{
#SpringBean
private IService service;
private BootstrapAjaxLink<String> noButton;
private ResponseMessage message;
private ProcessingPanel panel2;
private AlertPanel panel3;
private Panel replacedPanel;
public DetailsModal2(String id, IModel<UserDomain> model){
super(id);
replacedPanel = new AreYouSure("replacedPanel");
replacedPanel.setOutputMarkupId(true);
add(replacedPanel);
panel2 = new ProcessingPanel("replacedPanel");
panel3 = new AlertPanel("replacedPanel");
addButton(new BootstrapAjaxLink<String>("button", null, Buttons.Type.Warning, new ResourceModel("details")){
private static final long serialVersionUID = 1L;
#Override
public void onClick(AjaxRequestTarget target) {
// TODO Auto-generated method stub
//I was expecting to see this panel
addNewPanel(panel2,target);
// this puts this button invisible
this.setVisible(false);
target.add(this);
//this changes the label of the No button to Close
noButton.setLabel(Model.of("Close"));
target.add(noButton);
if(!service.retrieveData())
{
message = service.addUser("X");
if(message == null){
panel3.updateClassAndText(true);
addNewPanel(panel3,target);
}
else {
panel3.updateClassAndText(false);
addNewPanel(panel3,target);
System.out.println(""+ message.getError());
}
}//close if
else if(service.retrieveData())
{
message = service.removeUser("X");
if(message == null){
panel3.updateClassAndText(true);
addNewPanel(panel3,target);
}
else{
panel3.updateClassAndText(false);
addNewPanel(panel3,target);
System.out.println(""+ message.getError());
}
}
else{
System.out.println("It was not possible to access the db");
}
}
}
});
noButton = new BootstrapAjaxLink<String>("button", null, Buttons.Type.Primary){
private static final long serialVersionUID = 1L;
#Override
public void onClick(AjaxRequestTarget target) {
close(target);
}
}.setLabel(Model.of("No"));
addButton(noButton);
}
public void addNewPanel(Panel addpanel, AjaxRequestTarget target ){
Panel newPanel = null;
newPanel = addpanel;
newPanel.setOutputMarkupId(true);
replacedPanel.replaceWith(newPanel);
target.add(newPanel);
}
}//close class

Alright so here is my code. This should be really simple but it doesn't want to work with me for some reason. Raycast sends a ray from the mouse, if it hits an object with a tag, it assigns a number to a variable. If it doesn't hit an object, then it sets the variable as -99. For some reason mine is hanging on:
A. I don't hit the objects, it outputs -99 the first time but after that it hangs on getting assigned 4.
B.I hit the objects and it will work just fine. After I click OFF the objects it hangs on the variable from the object I just hit previously.
em.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameFunctions : MonoBehaviour {
int Hitnum = -99;
void Start () {
}
void Update () {
if (Input.GetMouseButtonDown (0)) {
objectCheck ();
}
}
//end of UPDATE function
public void objectCheck () {
RaycastHit hit;
Ray ray = camera.ScreenPointToRay (Input.mousePosition);
if (Physics.Raycast (ray, out hit, 10000.0f)) {
if (hit.collider.tag == "Box") {
Hitnum = 1;
} else if (hit.collider.tag == "Sphere") {
Hitnum = 2;
} else if (hit.collider.tag == "Pyramid") {
Hitnum = 3;
} else if (hit.collider.tag == "Trapezoid") {
Hitnum = 4;
} else {
Hitnum = -99;
}
}
Debug.Log (Hitnum);
}
//end of check
}
Thanks in advance. This is driving me nuts because it should be simple.
EDIT: posted full code this time, yes all of it. I should mention that there are no other objects with tags, it's just null space. This was supposed to be a very basic shape identifier for kids.
EDIT:EDIT: I expect it to put out -99 if you do not hit the object. Later I will probably do something with the numbers but right now I jest need to fix this.
Restarted unity, everything works fine now. Thanks. Looked through my settings to see what had changed. I earlier deleted the background that had a background tag on it. I guess unity decided that if there is not hit on raycast, it will get the object that it last hit?
I am using Google place API in my application for searching location. When user input text in edit field then the API called and resulted output will shown in a list.
I implemented it successfully but the problem is that each time edit field text changes, the list is not repainting and output is added to the end of the list. I want every time the text changes in the edit text field, the list must remove its previous content that are invalid.
This can be seen in pictures:
For Implementing this, I have written this code:
public final class MyScreen extends MainScreen {
/**
* Creates a new MyScreen object
*/
private Vector _listElements;
ListField list;
JSONObject[] jsonobject;
EditField editfield;
String url = "https://maps.googleapis.com/maps/api/place/autocomplete/json?input=";
String[] locationName;
VerticalFieldManager verticalFieldManager = new VerticalFieldManager();
public MyScreen() {
ButtonField search = new ButtonField("Search");
_listElements = new Vector();
list = new ListField();
ListCallback _callback = new ListCallback(this);
// Set the displayed title of the screen
setTitle("Search Edit Field");
editfield = new EditField();
editfield.setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
list.invalidate();
createField();
}
});
}
});
list.setCallback(_callback);
add(editfield);
add(new SeparatorField());
verticalFieldManager.add(list);
add(verticalFieldManager);
}
protected void createField() {
ShowList();
reloadList();
}
private void reloadList() {
list.setSize(_listElements.size());
}
class ListCallback implements ListFieldCallback {
MyScreen listDemoScreen;
public ListCallback(MyScreen listDemoScreen) {
this.listDemoScreen = listDemoScreen;
}
public void drawListRow(ListField list, Graphics g, int index, int y,
int w) {
String text = (String) _listElements.elementAt(index);
list.setRowHeight(getFont().getHeight());
g.drawText(text, 0, y, 0, -1);
}
public Object get(ListField list, int index) {
return _listElements.elementAt(index);
}
public int indexOfList(ListField list, String prefix, int string) {
return _listElements.indexOf(prefix, string);
}
public int getPreferredWidth(ListField list) {
return Display.getWidth();
}
}
protected void ShowList() {
HttpConnection httpConn;
InputStream in;
ConnectionFactory connFact = new ConnectionFactory();
ConnectionDescriptor connDesc;
String response;
String fieldText = editfield.getText();
connDesc = connFact.getConnection(url + fieldText
+ "%#&sensor=true&key=xxxxxxxxxxxxx"
+ ConnectionType.getConnectionType());
if (connDesc != null) {
httpConn = (HttpConnection) connDesc.getConnection();
try {
int responseCode = httpConn.getResponseCode();
if (responseCode == HttpConnection.HTTP_OK) {
in = httpConn.openInputStream();
StringBuffer buf = new StringBuffer();
int read = -1;
while ((read = in.read()) != -1)
buf.append((char) read);
response = buf.toString();
try {
JSONObject object = new JSONObject(response);
JSONArray ar = object.getJSONArray("predictions");
jsonobject = new JSONObject[ar.length()];
locationName = new String[ar.length()];
list.invalidate();
for (int i = 0; i < ar.length(); i++) {
jsonobject[i] = ar.getJSONObject(i);
_listElements.addElement(jsonobject[i]
.getString("description"));
}
} catch (JSONException e) {
e.printStackTrace();
}
}
} catch (IOException e) {
e.printStackTrace();
}
} else {
Dialog.alert("Connection not succeded");
}
}
protected boolean onSavePrompt() {
return true;
}
}
Update and Solution:
only modify this and this rest is working fine. As Peter Suggests, we can also put a Thread.sleep(time); in order to get the UI not blocked:
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
_listElements.removeAllElements();
createField();
}
});
I think your problem is simply that you do not clear the _listElements Vector when you request more data. So _listElements just gets bigger.
However there is a bigger problem here and that is that your code appears to be running networking operations on the Event Thread. What your should do in your changeListener. is start a Thread that requests the data, then repopulate the ListField when this tread gets data.
As a result of this change, the UI will not be blocked, and the List updates will become asynchronous, so your user could in fact enter another character into the EditField before the first Thread response comes back. To prevent this looking silly, you could delay the Thread processing for a fraction of second to see if another character is entered, and/or you could make sure that the EditField content was still the same as the requested characters before you repopulate it.
I personally prefer this asynchronous approach, but if it bothers you, you could put a 'please wait - loading' type screen to block the user until the response comes back.
Update
Remember that if you start a background Thread, you need to get back onto the Event Thread to do Ui Processing. Typically this is done simply by including your UI code within the run method of a Runnable that is invoked later, for example:
UiApplication.getUiApplication().invokeLater(new Runnable() {
public void run() {
// Ui Code in here
}
});
You should only put Ui Updating code in the runnable. Networking processing, or any other blocking action, should NOT be included.
I have a Silverlight 5.0 application and prvoide MS Word Automation functionality where the user can edit/add new document. I have gone through to MSDN pages but couldn't find any event that MS Word triggers after saving the document. The only event that talks about saving is the "DocumentBeforeSave" event that dosen't helps. I need to know when the MS Word finishes saving the document so that is it ready to save to server.
Can someone help me with this?
Any idea is very much approciated.
using MSWord = Microsoft.Office.Interop.Word;
namespace ConsoleApplication4
{
class Program
{
static void Main()
{
var app = new MSWord.Application();
var doc = app.Documents.Open(#"..\..\myDoc.docx");
app.DocumentBeforeSave += app_DocumentBeforeSave;
}
static void app_DocumentBeforeSave(MSWord.Document Doc, ref bool SaveAsUI, ref bool Cancel)
{
app.DocumentBeforeSave -= app_DocumentBeforeSave;
Cancel = true;
Doc.Save();
if(Doc.Saved){
//Now you know the document has saved
}
app.DocumentBeforeSave += app_DocumentBeforeSave;
}
}
}
The Save method doesn't run on a seperate thread, so it only returns once the Save is complete.
The DocumentBeforeSave event takes in a boolean call Cancel this is passed with the ref parameter, and setting it to true cancels the save that is about to take place.
You could set this to true, and then call Save yourself, this way you will know when the save has completed, as it runs on the same thread, something like this:
using MSWord = Microsoft.Office.Interop.Word;
namespace ConsoleApplication41
{
class Program
{
static void Main()
{
var app = new MSWord.Application();
var doc = app.Documents.Open(#"..\..\myDoc.docx");
app.DocumentBeforeSave += app_DocumentBeforeSave;
}
static void app_DocumentBeforeSave(MSWord.Document Doc, ref bool SaveAsUI, ref bool Cancel)
{
Cancel = true;
Doc.Save();
//Now you know the document has saved
}
}
}
