 ## Remarks  
  The overloads of the <xref:System.Numerics.BigInteger.op_Explicit(System.Decimal)~System.Numerics.BigInteger> method define the types to which or from which a <xref:System.Numerics.BigInteger> object can be converted. Language compilers do not perform this conversion automatically because it can involve data loss. Instead, they perform the conversion only if a casting operator (in C#) or a conversion function (such as `CType` or `CInt` in Visual Basic) is used. Otherwise, they display a compiler error.   
 
- Because this operation defines a narrowing conversion, it can throw an <xref:System.OverflowException> at run time if the <xref:System.Numerics.BigInteger> value is outside the range of the <xref:System.Int32> data type. There is no loss of precision in the resulting <xref:System.Int16> value if the conversion is successful.

There is no loss of precision in the resulting <xref:System.Int32> value if the conversion is successful.
 
 ## Examples
  The following example illustrates the conversion of <xref:System.Numerics.BigInteger> to <xref:System.Int32> values. It also handles an <xref:System.OverflowException> that is thrown because the <xref:System.Numerics.BigInteger> value is outside the range of the <xref:System.Int32> data type.

+## Remarks  
+ This method is called during message preprocessing to handle command keys. Command keys are keys that always take precedence over regular input keys. Examples of command keys include accelerators and menu shortcuts. The method must return `true` to indicate that it has processed the command key, or `false` to indicate that the key is not a command key. This method is only called when the control is hosted in a Windows Forms application or as an ActiveX control.  
+
+ The <xref:System.Windows.Forms.Control.ProcessCmdKey%2A> method first determines whether the control has a <xref:System.Windows.Forms.ContextMenu>, and if so, enables the <xref:System.Windows.Forms.ContextMenu> to process the command key. If the command key is not a menu shortcut and the control has a parent, the key is passed to the parent's <xref:System.Windows.Forms.Control.ProcessCmdKey%2A> method. The net effect is that command keys are "bubbled" up the control hierarchy. In addition to the key the user pressed, the key data also indicates which, if any, modifier keys were pressed at the same time as the key. Modifier keys include the SHIFT, CTRL, and ALT keys.
