Storing MongoDB tree using Materialized Paths pattern -

-

I need to duplicate a directory structure in Mangond. I have read about the patterns of physical routes and I need to use it

Patterns of physical routes store each tree node in a document; In addition to the tree node, the document stores as the ancestors of the nodes in the form of a string or as an ID (s) of path

The problem with this is that _ID should be unique, but in my case the directory The name must support duplicates (you can have 2 ore more directories with the same name).

Any thoughts? Thank you.

c# - Highlight all words containing a letter in a richtextbox -

Private Zero Button 208_Click (Object Sender, EventArgs E) {HighlightFrage (Rich Textbox 1, "A", Color. Yellow); } It exposes all the words with a word "a", but I'm not sure how to highlight the length of the spaces. Thank you. You can use the method to find incidents of sub-location. Then, use the property to change the colors back to Highlight colors for each event. int len ​​= richTextBox.TextLength; Int index = 0; String textconfind = "A"; // This will highlight the text you are viewing (index & lt; len) {richTextBox.Find (textToFind, index, len, RichTextBoxFinds.None); RichTextBox.SelectionBackColor = Color.Yellow; Index = rich textbox. Lesson Index (texttofind, index) + textaophind Langeline; } If you want...

Do you know about a problem due to Admob not being able to click on interstitial ads and therefore on Nexus 5 devices Have not brought any revenue? Fact: It does not have intermediate ads - some clickable, but mostly no . It comes with the old standalone Google Admob SDK and with the new Google Play Services SDK. It is on Nexus 5 with Android 4.4.2 , but it is possible that other devices are also affected. This happens in many programs in the Google Play Store - I'm not only with my application. For example, you can not Galaxy Nexus (Nexus 3), Galaxy S, on the HTC One. Below is a screenshot that opens the small info button in the clickable below the ad and OK, the Close X button also looks working properly , Though clicking on the ad does not happen - like it does not exist or something on it. Do you know of any solutions or possible solutions to the problem? Thanks! --- Update - - This activity declaration is: & amp; Activity Activity:...

I am trying to add a JTabbedPane to a panel, as well as for control I am using Migrates with the following buttons. However, I can not even get the JTabbedPane to fill without the buttons when they are not needed. The following SSCCE: public static zero main (string [] args) {jpn panel = new zpinal (new megallout (new lc.)
