IsAsyncBusy Property

public bool IsAsyncBusy {get;}

'Declaration
 
Public ReadOnly Property IsAsyncBusy As Boolean

'Usage
 
Dim instance As RasterCodecs
Dim value As Boolean
 
value = instance.IsAsyncBusy

public bool IsAsyncBusy {get;}

public boolean isAsyncBusy(Object operation)

 get_IsAsyncBusy(); 

public:
property bool IsAsyncBusy {
   bool get();
}

Property Value

The RasterCodecs object supports getting information and loading image files asynchronously through the use of the GetInformationAsync(String,Boolean,Int32,Object) and LoadAsync(String,LeadRect,Int32,CodecsLoadByteOrder,Int32,Int32,Object) methods.

You can call one asynchronous operation per RasterCodecs object at a time. To determine whether the RasterCodecs object is busy with a previous asynchronous operation, use IsAsyncBusy property. This is the equivalent of the WebClient.IsBusy property of AsyncWebClient.

You can also use the CancelAsync method to cancel any current asynchronous operation in this RasterCodecs object. This is the equivalent of calling WebClient.CancelAsync on AsyncWebClient.

Note:UseAsync, AsyncWebClient, IsAsyncBusy, and CancelAsync are only applicable when the GetInformationAsync(String,Boolean,Int32,Object) or LoadAsync(String,LeadRect,Int32,CodecsLoadByteOrder,Int32,Int32,Object) was with the versions that take a System.Uri parameter. The versions that take a System.String or a System.IO.Stream does not use a System.Net.WebClient object internally. If you want to check the progress or cancel the operation then use the LoadImage event as normal.
