FOXYPREVIEWER NEW HOME - www.foxypreviewer.com

As everybody knows, the cool and friendly structure of CodePlex is no longer available, so I decided to create a separate home for it.

From now on, all the releases, documentation, FAQS and more information will be available at www.foxypreviewer.com

Although CodePlex is still available as "ReadOnly", some people had difficulties downloading the latest release and documentation, so some other helpful guys have published some versions of these files. I would like to ask you to remove them, to avoid offering deprecated versions, because that makes it extremely difficult for all of us to provide support for old versions.

I have already a new version with some cool new features ad fixes, and I hope to publish it very soon.

See you at www.foxypreviewer.com !!!




www.reportlistener.com from 2007-08-23

Visual FoxPro 9.0 includes several major improvements to the crusty old Report Writer, making it a powerful, dynamic tool. One the primary ways to extend the capabilities of the Report Writer is through custom Report Listener classes. These classes allow you to hook into the report generation process to customize the appearance of your report. This site is dedicated to the sharing of custom Report Listener classes among the members of the Visual FoxPro community.

Converting General fields to Blob fields

 - The new Blob data type in VFP 9 is a General killer--they're much easier to work with than General. Unfortunately, there isn't an easy way to convert the contents of existing General fields into Blob fields; once you've put an image into a General field, it's all but impossible to get it back out. GeneralToBlobListener is a ReportListener subclass that handles this task painlessly.

HTML Preview with a Navigation Pane

 - Uses a custom ReportListener class and a helper class that work together to generate the output in HTML and GIF files. This HTML file is gererated through an XSL Transformation over a XML document that keeps some metadata of the preview output.

Using the GDI+ FFCs to work with output

 - This sample uses the GDI+ foundation classes to change the StringTrimming behavior for the field in the detail band of the report. Note that you have to make one manual change to the report as specified.

 - Taking advantage of GDI+ usage in Visual FoxPro 9 this class generates a PDF Document that will look exactly as your original report. Limitations: All the content of the report will be exported as an image to the PDF document (this will change in future versions). Works only on Visual FoxPro 9 (this will change in future versions).

Insert Images into an RTF control using GDIPlusX

The RichText control that ships with VFP is very useful for providing a formatted text edit box. While this control does support the displaying of images, there is nothing built in to the control that allows you to insert an image. I have included a function below that will allow you insert an image into the RichText control at the current cursor position.
Just specify the object reference to the RTF control and the fullpath of the image you want to insert. The image can be in any format supported by the GDIPlus library (BMP, JPEG, GIF, TIFF, EMF, PNG, etc...). You can also optionally specify the Width and Height you would like the image to be rendered.
This function requires the GDIPlusX library which can be downloaded from the VFPX project site: https://vfpx.codeplex.com/wikipage?title=GDIPlusX&referringTitle=Home.

Blending Two Images Using GDIPlusX

After seeing a post on the Micrsoft forums. I set out to try and solve how to blend two images using GDI+. I could find little information on the web on how to solve this particular problem, so I came up with my own technique (with some excellent help from Craig Boyd).
Here is a sample blended image and the VFP / GDIPlusX code that I used to create it.

Paste this code into a PRG and run it. This code requires the GDIPlusX library from VFPX.
Local lcPict1, lcPict2

m.lcPict1 = Getpict()
If File(m.lcPict1)
   m.lcPict2 = Getpict()
   If File(m.lcPict2)
      ImageAlphaBlend(m.lcPict1, m.lcPict2)

Function ImageAlphaBlend(tcPictLeft, tcPictRight)
* Author: Bo Durban *

   Local loColorMatrix As xfcCOlorMatrix
   Local loImageLeft As xfcImage
   Local loImageRight As xfcImage
   Local loBitmapPart As xfcBitmap
   Local loBitmapLeft As xfcBitmap
   Local laImageAttribs[1]
   Local loGfxLeft As xfcGraphics
   Local loGfxPart As xfcGraphics
   Local loGfxScreen As xfcGraphics
   Local lnAlphaSteps, lnBlendPercentage, lnWidthOpaque, lnStep, lnHeightImage, lnLeftStart

** Sets the number of Alpha blend steps used to render the blend.
** The max is 256. lower steps equals lower quality, but higher speed
   m.lnAlphaSteps = 128
** Sets the percentage of the image that is blended
   m.lnPercentageBlend = .75

   Dimension laImageAttribs[m.lnAlphaSteps]

** Requires the GDIPlusX library (version 1.20 beta)
** http://www.codeplex.com/VFPX/Release/ProjectReleases.aspx?ReleaseId=15083
   Do (Locfile("SYSTEM.APP"))
   With _Screen.System.Drawing

      m.loImageRight = .Image.FromFile(m.tcPictLeft)
      m.loImageLeft = .Image.FromFile(m.tcPictRight)

** Force the left image to be the same size as the right image
      m.loBitmapLeft = .Bitmap.New(m.loImageRight.Width, m.loImageRight.Height)

      m.lnWidthOpaque = m.loImageRight.Width * (1 - m.lnPercentageBlend) / 2
      m.lnWidthPart = Ceiling((m.loBitmapLeft.Width-m.lnWidthOpaque*2)/m.lnAlphaSteps)
      m.loBitmapPart = .Bitmap.New(m.lnWidthPart, m.loBitmapLeft.Height)

** Pre-fill ImageAttributes with Alpha ColorMatrix blend for performance
** The biggest advantage to doing this is if you were processing multiple
** set of images at a time, which we aren't doing here.

      For m.lnCurrentStep = 1 To m.lnAlphaSteps
         laImageAttribs[m.lnCurrentStep] = .Imaging.ImageAttributes.New()
         m.loColorMatrix.Matrix33 = m.lnCurrentStep/m.lnAlphaSteps

** Adjust these for preferred image quality vs. speed
*m.loGfxLeft.InterpolationMode = .Drawing2D.InterpolationMode.Default
*m.loGfxLeft.CompositingQuality = .Drawing2D.CompositingQuality.Default
*m.loGfxLeft.SmoothingMode = .Drawing2D.SmoothingMode.Default

** Use integers instead of floats for performance
      m.loGfxLeft.UsePrecision = .F.
** Minor speed increase accessing this property once
      m.lnHeightImage = m.loImageRight.Height

      For m.lnCurrentStep = 1 To m.lnAlphaSteps
         m.lnLeftStart = m.lnCurrentStep*m.lnWidthPart + m.lnWidthOpaque

** Draw partial right image to part
         m.loGfxPart.DrawImage(m.loImageRight, ;
            0,0,m.lnWidthPart,m.lnHeightImage, ;
            m.lnLeftStart,0,m.lnWidthPart,m.lnHeightImage, ;

** Draw part to left image with Alpha blend
         m.loGfxLeft.DrawImage(m.loBitmapPart, ;
            m.lnLeftStart,0,m.lnWidthPart,m.lnHeightImage, ;
            0,0,m.lnWidthPart,m.lnHeightImage, ;
            .GraphicsUnit.Pixel, ;


** Draw last opaque part of right image
      m.loGfxLeft.DrawImage(m.loImageRight, ;
         m.loImageRight.Width-m.lnWidthOpaque, 0, m.lnWidthOpaque, m.lnHeightImage, ;
         m.loImageRight.Width-m.lnWidthOpaque, 0, m.lnWidthOpaque, m.lnHeightImage, ;

** Render to the screen
      m.loGfxScreen = .Graphics.FromHWnd(_Screen.HWnd)

** Or you can save it to a file



Bo Durban - Moxiedata Blog - Display the Print Dialog Using PrintDlgEx

Display the Print Dialog Using PrintDlgEx

As I mentioned in my post from 9/29/2008, Microsoft removed the Printer button from the "Page Setup" dialog in Vista. It was reccommneded to use the "Print" dialog to change printer preferences. However, the "Print" dialog option is not always available on the menu, and there is no simple call to activate the dialog.
In my post from 9/29, I provided code for displaying the DocumentProperties dialog. This populates a DEVMODE structure from the Advanced Properties dialog for a specific printer. In today's post, I provide sample code for displaying the Print dialog using the PrintDlgEx API function. This is the dialog Microsoft recommendeds for setting printer options in Vista. This dialog populates a DEVMODE structure also, however, it includes the ability to select a printer and specify a print range too.

Paste this code into a PRG and run it. It will display user chosen options to the screen.
While this dialog is meant to replace missing functionality from SYS(1037) in Vista, this sample does not update your user preferences. You will need to update those based on the user action (see "Action" in the code below).
Note that the PrintDlgEx API function works with Windows 2000 and later.
