Tento článok ukazuje, ako zachytiť akúkoľvek formu alebo okno vrátane obrazovkydo Visual Basic obraz objektu. Raz na obrazovke obraz je zachytená vObrázok objekt, ľahko vytlačia, použitím PaintPicture metódyVisual Basic tlačiareň objektu.
DALSIE INFORMACIE
Zahrnuté príklad poskytuje niekoľko užitočných rutiny pre snímanie obrázkov.Všetky rutiny napísali pracovať podľa oboch 16 - a 32-bitovéPlatformách Windows a obsahova paletou podporu. Rutiny vnapríklad môžete:
  • Zachytiť celý obsah formulára.
  • Zachyťte klient oblasť formulára.
  • Digitalizáciu celej obrazovky.
  • Zachytenie aktívneho okna na obrazovke.
  • Zachytiť akejkoľvek časti každého okna definovaný popisovač.
  • Vytvoriť objekt obrázka z bitovej mapy a paletu.
  • Tlačiť obrázok objekt čo najväčšie na stránke.
Visual Basic 4.0 bol zavedený nový objekt obrázka. Objekt typu obrázok jeskutočne štandardný typ OLE a to je zdokumentovaná v ovládacom prvkuDeveloper's Kit (CDK.)

CDK zahŕňa funkciu OleCreatePictureIndirect, ktoré môžete použiť naZostrojte nové objekty obrázkov z Visual Basic 4.0. RutinnéCreateBitmapPicture v príklade vyzýva OleCreatePictureIndirect vybudovaťObrázok objektu popisovač bitová mapa a rukoväť na palete. AkObrázok obsahuje platný paletu, Visual Basic bude vedieť ho použiť prirenderovanie obraz na obrazovke alebo tlačiareň. CreateBitmapPicturerutinné používa rutina CaptureWindow na výstavbu obrázkových objektovobsahuje bitovú mapu časť alebo všetky okna.

CaptureWindow rutiny v príklade zachytáva akúkoľvek časť oknavzhľadom na jeho rukoväť a okno. Rutinné zahŕňa niekoľko parametrov preopisujúci presné časť okna zachytiť. Zachytiť okno dielaskopírovaním na obrazovke obrázok okna do nových bitová mapa. To tiežskontroluje, či obrazovke má paletu a ak áno, to robí jej kópiu.CaptureWindow potom volá CreateBitmapPicture na výstavbu bitová mapa zNovovytvorené bitovej mapy a palety.

CaptureForm, CaptureClient, CaptureScreen a CaptureActiveWindowrutiny zahrnuté do všetkých príklad použiť CaptureWindow na zachytenie špecifickésystém Windows. CaptureForm a CaptureClient ako aj volať digitalizačného okna a preniesť hoVlastnosť hWnd forme objektu. CaptureScreen jednoducho dostane rukovätiHorné okno stole a volania CaptureWindow. Podobne, CaptureActiveWindowlen dostane rukoväť okno aktívneho okna a vyzýva CaptureWindow.

Akonáhle požadovaný obraz je zachytená v objekte obrázok, je to ľahko tlačiťv jazyku Visual Basic 4.0 metódou PaintPicture tlačiarne objektu.Príklad poskytuje rutina PrintPictureToFitPage, ktorý používaPaintPictureMethod tlač čo najväčšie v zachytených obrázkovtlačiteľná oblasť pre stránku.

Príklad

  1. Začať nový projekt. Form1 sa vytvorí na základe predvoleného nastavenia.
  2. Miesto šesť CommandButtons formulára pozdĺž ľavej strany.
  3. Miesto jedného obrázka poli vo formulári napravo od tlačidiel.
  4. Vložte nasledujúci kód v Form1:
          '--------------------------------------------------------------------      ' Capture the entire screen.      Private Sub Command1_Click()         Set Picture1.Picture = CaptureScreen()      End Sub      ' Capture the entire form including title and border.      Private Sub Command2_Click()         Set Picture1.Picture = CaptureForm(Me)      End Sub      ' Capture the client area of the form.      Private Sub Command3_Click()         Set Picture1.Picture = CaptureClient(Me)      End Sub      ' Capture the active window after two seconds.      Private Sub Command4_Click()         MsgBox "Two seconds after you close this dialog " & _            "the active window will be captured."         ' Wait for two seconds.

Private Sub Command5_Click()         PrintPictureToFitPage Printer, Picture1.Picture         Printer.EndDoc      End Sub      ' Clear out the picture box.      Private Sub Command6_Click()         Set Picture1.Picture = Nothing      End Sub      ' Initialize the form and controls.      Private Sub Form_Load()         Me.Caption = "Capture and Print Example"         Command1.Caption = "&Screen"         Command2.Caption = "&Form"         Command3.Caption = "&Client"         Command4.Caption = "&Active"         Command5.Caption = "&Print"         Command6.Caption = "C&lear"         Picture1.AutoSize = True      End Sub      '--------------------------------------------------------------------					
  5. Pridať nový štandardný modul do projektu (module1 v predvolenom nastavení).
