I tried to get MediaFormatModel, MediaModel, MediaFolderModel etc with the help of MediaService but only the MediaContainer is not possible to get from MediaService and I tried with ModelService. Only one possibility I found that by getting MediaModel we can get the MediaContainerModel but I need to get specific MediaContainerModel by passing qualifier. Like for example:
final MediaModel mm1 = mediaService.getMedia(catalogVersion, "picture515x515");
final MediaFormatModel mf1200 = mediaService.getFormat("1200x1200");
final MediaFolderModel mfm = mediaService.getFolder("convertedimages");
any help?
You can always retrieve models using the flexiblesearh getModelByExample
CatalogVersionModel catalogVersion = catalogVersionService.getCatalogVersion("yourCatalogName", "version");
MediaContainerModel container = new MediaContainerModel();
container.setCatalogVersion(catalogVersion);
container.setQualifier("yourQualifier");
try
{
container = flexibleSearchService.getModelByExample(container);
}//no container found
catch (final ModelNotFoundException ex)
{
...
}
private MediaContainerModel getExistingMediaContainer(CatalogVersionModel catalogVersion, String qualifier) {
final String query = "SELECT {" + MediaContainerModel.PK + "} FROM {" + MediaContainerModel._TYPECODE + "} "
+ "WHERE {" + MediaContainerModel.QUALIFIER + "} = ?qualifier AND " + "{" + MediaContainerModel.CATALOGVERSION + "} = ?catalogVersion";
final FlexibleSearchQuery fQuery = new FlexibleSearchQuery(query);
fQuery.addQueryParameter("qualifier", qualifier);
fQuery.addQueryParameter("catalogVersion", catalogVersion);
final SearchResult<MediaContainerModel> searchResult = flexibleSearchService.search(fQuery);
if (searchResult.getTotalCount() > 0) {
return searchResult.getResult().get(0);
} else {
return null;
}
}
I got the solution we can get as follows
#Autowired
MediaContainerService mediaContainerService;......
MediaContainerModel mediaContainer = null;
try
{
mediaContainer = mediaContainerService.getMediaContainerForQualifier("testContainer");
}
catch (final Exception e)
{
mediaContainer = createMediaContainer("testContainer");
}
mediaContainer.setCatalogVersion(catalogVersion);

I understand the limitation of the API with the 100K limit, and MS's site says as a work around "you can work around this limitation by adding code to iterate over, and filter on, a facet with less that 100K documents per facet value."
I'm using the "Back up and restore an Azure Cognitive Search index" sample solution provided by MS. (https://github.com/Azure-Samples/azure-search-dotnet-samples)
But can some when tell me where or how I implement this "iterate loop" on a facet" The facetable field I'm trying to use is "tributekey" but I don't know where to place the code in the below. Any help would be greatly appreciated.

In this app the recycler view creates the "rooms" and if the room is selected the textview and 2 other values are put in to the RoomTable. these are stored and used in a service to check if ether of the other to values change. Everything works as intended unless i use the swip-to-refresh witch runs the recycler-view again. If i do not refresh and i select the same item in the recycler-view it will remove it from CountCheck . However if i run the refresh and select the same recycler-view item that i selected previously it will add it instead of removing it. This Makes no since to me because i use a for loop to Check the CountCheck.get(i).RoomName aka the textview and if the names are the same then my if statement will remove instead of add. is it somehow possible i'm ending up with 2 CountCheck Objects????? with the same name???? Please I'm out of ideas on this one. Thanks.
I dont remember why. Maybe someone can explain but i changed this line
if (roomname.getText() == CountCheck.get(i).RoomName)
To this
if (roomname.getText().equals(CountCheck.get(i).RoomName));
and that fixed the issue. please let me know the difference if you are reading this.
In Java 8, the Container class has an void add(Component comp, Object constraints) method that adds the component with a constraints information. I want to build a GUI with three panels, where pressing a button would result in switching the constraint information of the components that do not include the button object. How is it possible to switch the constraint information?
EDIT:
I tried the following:
private Map<SpecUITitlePanel, GridBagConstraints> constraints = new Hashtable<SpecUITitlePanel, GridBagConstraints>();
[…]
switchPanelsButton.setText( "Switch panels");
switchPanelsButton.addActionListener( new java.awt.event.ActionListener() {
public void actionPerformed( final java.awt.event.ActionEvent event) {
switchPanelsActionPerformed( event);
}
[…]
private void switchPanelsActionPerformed( final java.awt.event.ActionEvent event) {
boolean swapped = false;
final GridBagLayout layout = (GridBagLayout) getLayout();
final Iterator<SpecUITitlePanel> keysIter = constraints.keySet().iterator();
// summaryPanel, testPanel
while (keysIter.hasNext() && layout != null) {
final SpecUITitlePanel key = keysIter.next();
final String title = key.getTitle();
final Iterator<SpecUITitlePanel> keysIter2 = constraints.keySet().iterator();
while (keysIter2.hasNext()) {
final SpecUITitlePanel key2 = keysIter2.next();
final String title2 = key2.getTitle();
if (!title.equals( title2)) {
if (!title.contains( BUTTON_PANEL_TITLE) && !title2.contains( BUTTON_PANEL_TITLE)) {
// swap components
String message = "component = " + title + ", "
+ constraints.get( key) + "; component2 = " + title2
+ ", " + constraints.get( key2);
System.out.println( message);
final GridBagConstraints value = constraints.get( key);
final GridBagConstraints value2 = constraints.get( key2);
constraints.put(key, value2);
layout.setConstraints( key, value2);
constraints.put(key2, value);
layout.setConstraints( key2, value);
swapped = true;
message = "component = " + title + ", "
+ constraints.get( key) + "; component2 = " + title2
+ ", " + constraints.get( key2);
System.out.println( message);
}
}
}
}
if (swapped) {
repaint();
}
}
The relevant part of the output is
component = Test, java.awt.GridBagConstraints#5179288b; component2 = tna.rads.main_panel.violation_summary_panel, java.awt.GridBagConstraints#f1a7ed2
component = Test, java.awt.GridBagConstraints#f1a7ed2; component2 = tna.rads.main_panel.violation_summary_panel, java.awt.GridBagConstraints#5179288b

try passing latitude as 33.4965 & longitude as -112.205
i'm getting an exception object reference to invalid object in the line
**typename = xn["type"].InnerText;**
when i debug step by step there is no such attribute like ["type"]
Also there are some other lingual character why?
How could i resolve this issue.
I'm not familiar with c# and Im not sure if your code is correct at all(e.g. types is not an attribute, it's an elementNode).
Assuming that your code is correct and you can select nodes by using node['nameOfChildNode'] , when you inspect the XML-File: http://maps.googleapis.com/maps/api/geocode/xml?latlng=33.4965,-112.205&sensor=false you will see that there are address_components with 2 <type>'s and also address_components without any <type> .
I guess your code breaks not at the missing <type>, it breaks when you try to access a property(InnerText) of the missing <type>.
What you can do: use selectSingleNode to select the <type> and when it returns null implement a fallback or leave the further processing.
http://maps.googleapis.com/maps/api/geocode/json?latlng=33.4965%20,%20-112.205&sensor=false
returns
{
"results" : [],
"status" : "ZERO_RESULTS"
}
Therefore
XmlNode element = doc.SelectSingleNode("//GeocodeResponse/status");
if (element.InnerText == "ZERO_RESULTS")
{
return ("No data available for the specified location");
}
is not catching ZERO_RESULTS.
I am not familiar with C# so I cannot help further.
I’m writing an application that communicates with some hardware using the MODBUS protocol.
I'm using this sample from Code Project.
While trying to optimize the code (mainly the PollFunction function), I've encountered with a very strange threads lock.
Instead of sending each line of string to the DoGUIUpdate delagate, I'm constructing a string array and sending it as a whole.
Doing so causes the application to crush with a System.Reflection.targetParametercountException: Parameter count mismatch error.
The original code:
public delegate void GUIUpdate(string paramString);
public void DoGUIUpdate(string paramString)
{
if (InvokeRequired)
BeginInvoke(new GUIUpdate(DoGUIUpdate), paramString);
else
lstRegisterValues.Items.Add(paramString);
}
private void PollFunction()
{
...
string itemString;
for (int i = 0; i < pollLength; i++)
{
itemString = "[" + Convert.ToString(pollStart + i + 40001) + "] , MB[" + Convert.ToString(pollStart + i) + "] = " + values[i];
DoGUIUpdate(itemString);
}
}
My code:
public delegate void GUIUpdate2(string[] paramString);
public void DoGUIUpdate2(string[] paramString)
{
if (InvokeRequired)
BeginInvoke(new GUIUpdate2(DoGUIUpdate2), paramString);
else
{
lstRegisterValues.Items.Clear();
lstRegisterValues.Items.AddRange(paramString);
}
}
string[] valuesStrings;
private void PollFunction()
{
...
valuesStrings = new string[pollLength];
for (int i = 0; i < pollLength; i++)
{
valuesStrings[i] = "[" + Convert.ToString(pollStart + i + 40001) + "] , MB[" + Convert.ToString(pollStart + i) + "] = " + values[i];
}
DoGUIUpdate2(valuesStrings);
}
Any advice will be welcome.
i think BeginInvoke(new GUIUpdate2(DoGUIUpdate2), paramString); is the problem...
the second parameter of "begininvoke" accepts a param object[] params which will result in the call DoGuiUpdate(string1,string2,string3) which is not what you want...
try encapsulate in the following way:
BeginInvoke(new GUIUpdate2(DoGUIUpdate2), new[]{ paramString });
