问题 How to Fullscreen in XE7, hiding both the top (title) and bottom (softkey) toolbar? In XE6 I could adjust the AndroidManifest to make my application go fullscreen and without the actionbar by writing in the application section: android:theme="@android:style/Theme.Holo.NoTitleBar.Fullscreen" > In XE7 this did no longer do the job, I found a Russian website with more information on the matter.

问题 In iOS 7 the default behavior of the statusbar is to be transparent, but that seems impossible in Delphi XE7. The statusbar always get the same color as the mainform (which was the default behavior in iOS 6). The Mainform.borderstyle controls if the statusbar is shown or not, but I cannot find any way to set it transparent.

问题 I have a TDBImage control on my form. Users can CTRL - V images in to it. They can also CTRL - X in the control to clear the image. When I later try to take the contents of that TDBImage as save it to my database I get memory access violations, in particular when I generate the memory stream. Naturally my first inclination is to see if the TDBImage is somehow empty before I do this (and clear the database field my self). But I can't seem to find a way to detect if the control has been CTRL -

问题 I have a small console app. I want to hide its window when it is called from my main program (with -hide as command line parameter) and show it when the user starts it (no command line param). This question suggests that using {$APPTYPE GUI} instead of {$APPTYPE CONSOLE} will hide the window. And indeed it works. But how do I make the window visible when ran by user?
