c# - Can I put commands after Form.Close()? -

-

In C #, suppose I'm in one form, and I pressed a button to close it. 

  this.Close (); Some_action (); // What can I do ??

Do I close the form or the thread dies and after that everything is lost?

What you are trying to do and depends on the context of the statement. If the form is being shut down, then primarily the owner of the message loop, you can not do any UI related stuff (e.g., you do not display another MessageBox If you are not doing this with any other window (which is not near the message loop), then you can do anything (even related to the UI) unless you manipulate the closed form object (You will get the ObjectDisposedException just by any Ta-like object).

By the way, the thread does not die as a result of shutdown . To close the main window, the message loop ends and not the thread. For example, the following program 

  Fixed zero main () {Application.Run (new form 1 ()); application. Rouen (new form 2 ()); }   will be closed after 
  after    (using a newly created message loop). This proves that thread is not dead.

Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never
