Oracle, virtualbox, how to import / insert a vdi file when the New and Add buttons are removed from the Virtual Media manager?

situation
	Oracle, please, don’t be Microsoft! It is a shame to remove capabilities from this wonderful software! The “new” and “add” buttons are removed from the Virtual Media manager from version 4.0.0 because simply they are idiot (I can’t find other logical reason). It is shame to reduce the capabilities of a too powerful application.

solution
	To add a vdi info your "Virtual Media Manager" do the follow: - Go at the "Settings" of any virtual machine. If you haven’t any, create a dummy (there is no need to create disk for it). - Go at the "Storage" section. - Click of the “ide controller” (or “sata controller”) - On the same line of the "controller" the two “add” buttons will be appeared, click on “Add hard disk” - Then click on “choose existing disk” - Select the vdi file and will be inserted to Virtual Media Manager. - From this point, you may use this disk in any Virtual machine you want.
attention
	The problem occurred in version 4.0.0 - 4.0.6 at least.

visual studio - c# / vb - Label is not transparent

Problem
Setting the Backcolor of the Label component to web -> Transparent, the Label is not transparent at all!

Solution
This is because MS is confused about what is really transparent! Forget the transparent effect between the components!
This Transparent color means that if you set Backgroundimage at the container where hosts the Label component, the Label will be transparent at the image that is loaded in the container.
In practice...
- create a Form
- set a Backgroundimage at the created form, load a jpg file...
- drop a Label compoent
- set the at Label component the property Backcolor to web -> Transparent

Now  you have a transparent Label in the way of Microsoft :(

Firebird sql; How to make the Firebird SQL server portable, supporting the network connections!!!

situation
	Firebird SQL server project, supports to be portable, as your application will use the same DLLs as the Firebird SQL server does; by this way you may open FDB files from your application without install the Firebird Server. The main disadvantage is that you can’t open the same FDB file from other application and of course there is no network support to open the FDB as remote database from other terminal(s). By the way, if you are interesting how you do this, search at the internet and at Firebird's official page. I’ll go further as I will show to you how to make the Firebird server portable as it is, with network support also!

Flex: how to make a image cache? (easier way) - REFdn4007673813

situation
	how to make a image cache?
problem
	adobe flex4 AS3.0 the image component how to load images save them to cache… and how apply them to Image components --- > page by dn
difficulty level
	9/10 :(
solution
	In order to make a cashe of the photos/images, I do the follow simple way: - With URLLoader I download the data… the "Complete" event gives me the "data" property… in this property the data of the image is in binary format (don't be afraid). I save this "data" to another variable (or array) of Object type. For this example, I named this variable "downloadData" you will see bellow. - In order to load the data on a visual component Image, I do the follow code: myImage.data=downloadData;

How to Cache Images in Your Flex Application - REFdn5077575832

Caching images in your Flex application can greatly improve performance and reduce the overhead of loading external resources.
And I’m not simply talking about using the cacheAsBitmap property to improve rendering performance or the cachePolicy property to speed up animations. I’m talking about caching the actual bitmap data of an image.
To get started, you’ll need a hash map to store the image data. A Dictionary or an associative array will also work just fine.
Loading an image for the first time is the same as usual. You create a new Image object and add a listener for the COMPLETE event:

var image : Image = new Image (); image.addEventListener (Event.COMPLETE, onImageComplete);

Once the image has finished loading, you add a copy of the bitmap data to the hash map using the image URL as the hash key:

private function onImageComplete (event : Event) : void {     var image : Image = event.target as Image;     if (! imageCache.containsKey (image.source))     {         var bitmapData : BitmapData = new BitmapData             (image.content.width, image.content.height, true);         bitmapData.draw (image.content);         imageCache.put (image.source, bitmapData);     } }

Now we can use the image as many times as we want without ever having to load it again!
To take advantage of this, you’ll need to check the hash map every time you create a new image (or change the source property) to see if you’ve already cached it:

var image : Image = new Image (); image.addEventListener (Event.COMPLETE, onImageComplete); if (imageCache.containsKey (imageURL)) {     image.source = new Bitmap (imageCache.getValue (imageURL)); } else {     image.source = imageURL; }

And that’s it!
If you have an application that loads a large number of images you may want to limit the number of cached images to prevent the Flash player memory usage from getting out of hand, but in general caching even several dozen large images only results in a slightly increased footprint.
