VB VSPrinter 从外部引入一个.emf文件设定A4纸打印,之后保存为.pdf文件

麻烦各位写个模板,加上一些注释
改改名字路径就能用的那那种.
我刚刚接触这个,不是很懂,请各位多多指教,谢谢!
好用的话,给加分!

建立一个PictureBox1,窗体中引用API,在得到CDN_SELCHANGE时,调用GetFilesName得到此时用户选中的 文件,代码如下:
Private Function GetFilesName(hWindow As Long) As String
   Dim hParent As Long
   Dim lRetValue As Long
   Dim theFileName(1024) As Byte
   For i = 0 To UBound(theFileName)
     theFileName(i) = 0
   Next
   hParent = GetParent(hWindow)
   lRetValue = SendMessage(hParent, CDM_GETFILEPATH, 1024, theFileName(0))
   GetFilesName = StrConv(theFileName, vbUnicode)
End Function
调用GetOpenFileName API的方法如下:
Public Function ShowOpenFileDlg(hParent As Long) As Long
   On Error GoTo lblExit
   Static strFilter As String
   strFilter = "All Pictures" & Chr(0) & "*.bmp;*.dib;*.jpg;*.gif;*.wmf;*.emf;*.ico;*.cur" & Chr(0) & _
   "Bitmap (*.bmp;*.dib)" & Chr(0) & "*.bmp;*.dib" & Chr (0) & _
   "JPEG (*.jpg)" & Chr(0) & "*.jpg" & Chr(0) & _
   "GIF (*.gif)" & Chr(0) & "*.gif" & Chr(0) & _
   "Metafile (*.wmf;*.emf)" & Chr(0) & "*.wmf;*.emf" & Chr(0) & _
   "Icons (*.ico;*.cur)" & Chr(0) & "*.ico;*.cur" & Chr (0) & _
   "All files (*.*)" & Chr(0) & "*.*" & Chr(0) & Chr (0)
   FrmPreview.Hide
   pointer = GetProcAddr(AddressOf wndProc)
   Dim MyID As Long
   With openfile
     .lStructSize = Len(openfile)
     .hwndOwner = hParent
     .hInstance = App.hInstance
     .lpstrFilter = strFilter
     .lpstrCustomFilter = ""
     .nMaxCustFilter = 0
     .nFilterIndex = 0
     .lpstrFile = filesname
     .nMaxFile = 1023
     .lpstrFileTitle = ""
     .nMaxFileTitle = 0
     .lpstrInitialDir = ""
     .lpstrTitle = ""
     .flags = OFN_ENABLEHOOK + OFN_HIDEREADONLY + OFN_ENABLETEMPLATE + OFN_EXPLORER
     .nFileOffset = 0
     .nFileExtension = 0
     .lpstrDefExt = ""
     .lCustData = 0
     .lpfnHook = pointer
     .lpTemplateName = "DLGOPENTEMP"
   End With
   ShowOpenFileDlg = GetOpenFileName(openfile)
lblExit:
End Function

在窗体中CALL函数模块,让Picture装载到VSPrint,,设置代码如下:
'---------------------预览报表
VSPrinter1.StartDoc
VSPrinter1.Zoom = 100 '显示比例为100%
VSPrinter1.RenderControl = Form1.Picture1.hWnd
'----------------------设置
With VSPrinter1
'设置标题
.FontSize = 16
.FontBold = True
.TextAlign = taCenterMiddle
.Paragraph = "打印人:张三"
.Footer = "打印日期: " & Format(Date, "yyyy/mm/dd ") & " 第 " & ipage & "页,共 " & pages & "页 "
.FontBold = True
.FontSize = 10
.TextAlign = taRightTop
.Paragraph = " "
.FontBold = False
.FontSize = 10
End With
VSPrinter1.EndDoc

没用过VSPRINTER控件,对方必定给你一些说明和示例的.你查看一下或咨询控件的提供方吧. 再看看别人怎么说的。
