Step-by-Step Example

1. Start Visual Basic. Form1 is created by default.



2. Draw a large picture box (Picture1) on the form.



3. From the File menu, choose New Module to create a new module. Put the following code in the module:

   
      DefInt A-Z
      global Const LF_FACESIZE = 32
      Type LOGFONT
         lfheight As Integer
         lfwidth As Integer
         lfescapement As Integer
         lforientation As Integer
         lfweight As Integer
         lfitalic As String * 1
         lfunderline As String * 1
         lfstrikeout As String * 1
         lfcharset As String * 1
         lfoutprecision As String * 1
         lfclipprecision As String * 1
         lfquality As String * 1
         lfpitchandfamily As String * 1
         lffacename As String * LF_FACESIZE
      End Type
   
      ' Enter each of the following 7 Declare statement on one, single line:
   
      Declare Function CreateFont% Lib "GDI" (ByVal h%, ByVal w%, ByVal e%,
         ByVal o%, ByVal n%, ByVal i%, ByVal u%, ByVal s%, ByVal c%,
         ByVal op%, ByVal cp%, ByVal q%, ByVal j%, ByVal f$)
      Declare Function createfontindirect Lib "GDI" (lplogfont As LOGFONT)
         As Integer
      Declare Function selectobject Lib "GDI" (ByVal hdc%, ByVal object%)
         As Integer
      Declare Function textout Lib "GDI" (ByVal hdc%, ByVal x%, ByVal y%,
         ByVal text$, ByVal ncount%) As Integer
      Declare Sub deleteobject Lib "GDI" (ByVal object%)
      Declare Function getdevicecaps Lib "GDI" (ByVal hdc%, ByVal nindex%)
         As Integer
      Declare Function gettextface Lib "GDI" (ByVal hdc As Integer,
         ByVal ncount As Integer, ByVal lpname As String) As Integer
   
      Global Const PROOF_QUALITY = 2
      Global Const FW_NORMAL = 400
    




4. Add the following code to the Form_Click event:

   
      picture1.Cls
      Dim hfont As Integer, holdfont As Integer
      Dim font As LOGFONT
      nvalue = getdevicecaps(picture1.hDC, 34)
      font.lfheight = 12
      font.lfwidth = 0
      font.lfescapement = 900
      font.lforientation = 900
      font.lfweight = 400    'This is normal
      font.lfitalic = Chr$(0)
      font.lfunderline = Chr$(0)
      font.lfstrikeout = Chr$(0)
      font.lfcharset = Chr$(0)
      font.lfoutprecision = Chr$(0)
      font.lfclipprecision = Chr$(0)
      font.lfquality = Chr$(2)
      font.lfpitchandfamily = Chr$(33)
      font.lffacename = "Courier New" + Chr$(0)
   
      hfont = createfontindirect(font)
      holdfont = selectobject(picture1.hDC, hfont)
      szfacename$ = Space$(80)
      retval% = gettextface(picture1.hDC, 79, szfacename$)
   
      nchars = Len(sometext$)
      picture1.CurrentX = 200
      picture1.CurrentY = 2000
      picture1.Print Left$(RTrim$(szfacename$), Len(RTrim$(szfacename$)) - 1)
      deleteobject hfont
    




5. Run the program. Click the form, not the picture. You'll see the phrase "Courier New" print sideways in the picture control, from the lower left to the upper left.
