Flex [original] Air calls the local EXE file to complete the screenshot Function

Air calls the local EXE file to complete the Function

 

The local EXE function is called here, mainly including two knowledge points: first, how to call the local EXE file (in fact, this is a kind of local function call on the desktop platform, for example, in addition to the EXE call, you can also call Python and other files.ArticleThe second is to retrieve bitmap data from the system clipboard.

1. Demo Structure

 

2. The screenshot class encapsulates the local call interface.

 Package  {  Import Flash. desktop. Clipboard;  Import  Flash. desktop. clipboardformats;  Import  Flash. desktop. nativeprocess;  Import  Flash. desktop. nativeprocessstartupinfo;  Import  Flash. display. bitmapdata;  Import  Flash. Events. event;  Import  Flash. Events. eventdispatcher;  Import Flash. Events. nativeprocessexitevent;  Import  Flash. filesystem. file;  Public   Class Screenshot Extends  Eventdispatcher {  Public   Static   Const Shot_complete: String = "shot_complete" ;  Private VaR _ shotcompleteevent: event = Null ;  Private VaR _ file: file = Null  ;  Private VaR _ nativeprocessstartupinfo: nativeprocessstartupinfo = Null  ;  Private VaR _ process: nativeprocess = Null  ;  Private VaR _ bitmapdata: bitmapdata = Null  ; Public Function screenshot (): Void  {_ File = File. applicationdirectory. resolvepath ("snapshot.exe" ); _ Nativeprocessstartupinfo = New  Nativeprocessstartupinfo (); _nativeprocessstartupinfo.exe cutable = _ File; _ Process = New  Nativeprocess (); _ shotcompleteevent = New Event (shot_complete );}  Public Function Shot (): Void  {_ Process. Start (_ nativeprocessstartupinfo); _ process. addeventlistener (nativeprocessexitevent. Exit, onexit );}  Private Function onexit (E: nativeprocessexitevent ): Void  {  If  (Clipboard. generalclipboard. hasformat (clipboardformats. bitmap_format) {_ bitmapdata =Clipboard. generalclipboard. getdata (clipboardformats. bitmap_format) as bitmapdata; dispatchevent (_ shotcompleteevent );}}  Public  Function get bitmapdata (): bitmapdata {  Return _ Bitmapdata? _ Bitmapdata as bitmapdata: Null  ;}}} 

 

3. Demo test class:

<? XML version = "1.0" encoding = "UTF-8"?> <S: Drawing wedapplication xmlns: FX = "http://ns.adobe.com/mxml/2009" Xmlns: S = "Library: // ns.adobe.com/flex/spark"Xmlns: MX = "Library: // ns.adobe.com/flex/mx" Applicationcomplete = "Applicationcompletehandler (event)"> <FX: SCRIPT> <! [CDATA [  Import  MX. Events. flexevent;  Private VaR SS: screenshot = New  Screenshot ();  Protected Function applicationcompletehandler (Event: flexevent ): Void {Stage. addeventlistener (keyboardevent. key_down, onkdown); SS. addeventlistener (screenshot. shot_complete, oncomplete );}  Protected Function openexe_clickhandler (Event: mouseevent ): Void  {Ss. Shot ();}  Private Function onkdown (E: keyboardevent ): Void  {  If (E. altkey & E. ctrlkey & E. keycode = 65) {Ss. Shot ();}}  Protected Function oncomplete (Event: Event ): Void  {Bimg. Source = SS. bitmapdata;}] > </FX: SCRIPT> <s: hgroup> <s: button id = "openexe" label = "openexe" Click = "openexe_clickhandler (event)"/> <s: bitmapimage id = "bimg"/> </S: hgroup> </S: windowedapplication>
