.net 3.5 - How to bind inverse boolean properties in WPF? -

-

I have an object that has a IsReadOnly property if this property is true, then I I would like to set the IsEnabled property on the button (for example).

I have to believe that I can do it as easily as IsEnabled = "{Binding Path =! IsReadOnly}" but it flies with WPF does not.

Do I have all the style settings? Just as any other bowl is set inversion of any other hair, it seems very simple enough for some. 

  & gt; button. Style & gt; & Lt; Style TargetType = "{x: type button}" & gt; & Lt; Style.Triggers & gt; & Lt; DataTrigger Binding = "{Binding Path = IsReadOnly}" Value = "True" & gt; & Lt; Setter property = "iced" value = "wrong" /> & Lt; / DataTrigger & gt; & Lt; Datatrigger binding = "{binding path = iside only}" value = "wrong" & gt; & Lt; Setter Property = "Iceded" value = "true" /> & Lt; / DataTrigger & gt; & Lt; /Style.Triggers> & Lt; / Style & gt; & Lt; /Button.Style>

You can use a ValueConverter that alters a bool property for you is.

[Value Conversion (Type (Bull), Typef (Bull)) Public Category Inverbosbonan Converter: IValueConverter {#region IValueConverter Member Public Object Convert (Object Value, Type Target Type, Object Parameter, System Globilization. (TargetType! = Typeof (bool)) New Invalid Operation exception throw ("Target should be a Boolean"); Back (Bool) Value;} Public Object Convertback (Object Value, Type Type, Object Parameter, System. Globalization. Cultural Information Culture) {New Notport Supported Exception ();} #endregion}

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.

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.
