dataviewer | Exposing charts from Java to the Web | Chart library

My task is to implement the Quick Look functionality in a way to present options for opening the chosen document. I'm using the UIDocumentInteractionController's PresentOptionsMenu method to display the options. The Quick Look icon is displayed but when I click on it then nothing happens. The popup with the options closes and the document is not opened.

What do I do wrong? Why is to document not opened after clicking on the Quick Look icon?

The popup displayed after selecting a document

My code is:

I am trying to export the table to flat file destination. Float column value (0.0911780821917808) is exported into 9.1178082191780821E-2 in flat file.

Table create table Test ( col1 float )

Col1 0.0911780821917808

Exporting this table to flat file destination. However exported to value "9.1178082191780821E-2" in .txt file. However correct value is coming in the DataViewer after OLE DB Source.

Please guide to export the value as it is to flat file.

Advance thanks for all your time

In a WinForms dataviewer project I've made a ComboBox to select a filter value. The list items come from of a database query. They are sorted descending. The ComboBox uses AutoCompleteMode.Append. Although the dropdown list is sorted descending, the AutoComplete always suggests the lowest matching value instead of the highest. This happens even if I explicitly populate the AutoCompleteCustomSource with descending data.

Does anyone know how to make the AutoComplete suggesting the highest matching value?

The ComboBox looks like this after typing "010":

This is a part of the dropdown list:
...
012-0020-00
010-0070-00
010-0069-00
010-0068-00
008-1018-00
...

Why this matters:
I will use this filter for various string data containing numbers, like parts codes, document codes, project codes etc. Newer entries have higher numbers. And the newest entries are queried most often. In the above example, 010-0070-00 ist the newest part code of the 010 group. Therefore I expect the AutoComplete to show 010-0070-00 after I have typed 010.

This project replaces an MS Access front end. An Access ComboBox suggests the highest value if the list is sorted descending resp. the lowest value if sorted ascending. But Access ComboBoxes are not WinForms controls.

Any suggestions are welcome.

I am writing a Qt application where I have QListWidget filled with QListWidgetItems and I want to create a new dialog on double click on QListWidgetItem. So I created a new dialog class as in this qt tutorial. Now, I added on_listWidget_itemDoubleClicked(QListWidgetItem* item) slot where I should create an instance of dialog class. But I want my main app to still operate and continue and just have dialog window show some info. So I cant just create an instance of dialog class and show it with exec() function.

So what i came up with is to have std::unique_ptr on my dialog class as class member of my main class, and invoke dialog with show() method. Everytime on_listWidget_itemDoubleClicked(QListWidgetItem* item) is called I will create new instance of dialog class with std::make_unique which should destroy old dialog and create a new one.

Is this generally a safe approach ? Or is there other standard way of solving such situation ?

EDIT

Here is example how I was thinking it might look:

The main class:

I am writing a Qt C++ app to show byte values and its hexdump right next to it. For that I am creating a new dialog, I have 2 QTableViews(each for byte representation or hexdump) and 1 class which inherits from QAbstractTableModel and 1 class which inherits from QStyledItemDelegate.

Now I would like to add functionality, that when I select something in first QTableView, it will also be selected in second QTableView.

In Qt's documentaion on model-view programming they do something similiar using command secondTableView->setSelectionModel(firstTableView->selectionModel()) But that doesn't work for me. I am also highlighting cells using my delegate(now its just in prototype phase) using paint method. Could it be because of this ?

I have a shiny application that takes an ID as input from the user and returns the results of the dataframe as a datatable in the "Show data" tab.

I am trying to assign the table results from the "Show data" tab to a list in the "Datasets" tab.

I am in the midst of building my HTML webpage and i wanted to implement a dark mode for my webpage. I've viewed quite alot of examples on the web and i tried to implement 1 from the web. However, i tried to link the HTML webpage and JavaScript together, but it seemed that my webpage still cannot change to dark mode. Is there something wrong with my code?

Let's say, I have some model UserModel.cs which looks like this:

I have created this simple generic interface:
