Associated Application ICONS

[nageswaragunupudi]

We mostly produce serious business applications. I doubt if this topic be of much practical use. Nonetheless, it can be an interesting diversion.

The idea is given any existing file, read the icon of the associated application and display.
For example, if the file is "some.xlsx" display the icon of Excel application, for "some.docx", display icon of the Word Application, etc.

Here, we will demonstrate how simple and easy to do this, using FWH.

Please note, we have to use existing file names.
Sample-1

Code: Select all  Expand view

XIMAGE( "some.pptx(256x256)")

Sample-2

Code: Select all  Expand view

  DEFINE DIALOG oDlg SIZE 510,500 PIXEL TRUEPIXEL
   ACTIVATE DIALOG oDlg CENTERED ON PAINT ( ;
      oDlg:DrawImage( "some.xlsx(16x16)", {,,,50} ), ;
      oDlg:DrawImage( "some.xlsx(32x32)", {,50,,100} ), ;
      oDlg:DrawImage( "some.xlsx(64x64)", {,100,,200} ), ;
      oDlg:DrawImage( "some.xlsx(256x256)", {,200,,500} ) )
 

Sample-3:
From next version

Code: Select all  Expand view

  DEFINE DIALOG oDlg SIZE 600,250 PIXEL TRUEPIXEL
   DEFINE BUTTONBAR oBar SIZE 80,80 2007

   for each c in { "DOCX", "XLSX", "PPTX", "PDF", "TXT" }
      DEFINE BUTTON OF oBar PROMPT c FILE "." + c,"." + c,"." + c, "." + c + "(16x16)"
   next

   ACTIVATE DIALOG oDlg CENTERED
 

Till FWH2206, we need to use existing file names.



Sample-4

Code: Select all  Expand view

#include "fivewin.ch"

function Main( cPath )

   DEFAULT cPath := "c:\aFiles\"   // your folder here

   XBROWSER DIRECTORY( cPath + "*.*" ) COLUMNS 1,2,3 ;
   TITLE "FILE ICONS" ;
   SETUP BrwSetup( oBrw, cPath )

return nil

static function BrwSetup( oBrw, cPath )

   WITH OBJECT oBrw
      :cHeaders := { "Name","Size","Date" }
      :nRowHeight := 34
      WITH OBJECT :aCols[ 1 ]
         :bBmpData := { || cPath + oBrw:aRow[ 1 ] }
         :bLDClickData  := { || ShellExecute( 0, "Open", cPath + oBrw:aRow[ 1 ],,, 1 ) }
      END
   END

return nil

Note: Easy to write but not fully optimized for speed.

Dear Rao,

Great work, many thanks!

Nice Rao.
I'm not clear on which command to use to get the icon

[Jimmy]

hi,

try this

c:\fwh\source\winapi\icons.c

Code: Select all  Expand view

HB_FUNC( ICON_READ )

c:\fwh\source\winapi\gdipfwh.cpp

Code: Select all  Expand view

HB_FUNC( ICON_READEX )

[hua]

Thanks Jimmy.
Any idea how to assign them to a BTNBMP?

try this
c:\fwh\source\winapi\icons.c

Code: Select all  Expand view

HB_FUNC( ICON_READ )

c:\fwh\source\winapi\gdipfwh.cpp

Code: Select all  Expand view

HB_FUNC( ICON_READEX )

hi,

Any idea how to assign them to a BTNBMP?

i have not work with CLASS TBtnBmp() yet

when look into Soure i found

//
// if user has directly assigned hBitmapX
//

i guess you can use "o:hBmp" to assign Result a hBitmap ... but i´m not sure about hIcon (from ICON_READ() )

For many years, I have used Axialis for all my bitmaps. Now they have Icon Generator which is a free download. They also sell many libraries, but include a huge number of free Google icons. With the generator, you can easily colorize those Google icons. You can also add overlays to them to create new icons.

Instead of bitmaps, I now use all vector icons ( created by IG ) on all of my bitmap bars. They work very nicely and are clean. You can buy a wide variety of styles already made, or you can build your own. In a large application, with many options, we often need custom icons.

Very simple.
See Sample-3 above

This is a very simple example you can try right now: This sample works with FWH1912

Code: Select all  Expand view

  DEFINE DIALOG oDlg

   @ 10,10 BTNBMP PROMPT "MS-WORD"  FILE "T.DOCX(64X64)"    SIZE 50,60 PIXEL 2007 OF oDlg

   @ 10,70 BTNBMP PROMPT "MS-EXCEL" FILE "SOME.XLSX(64x64)" SIZE 50,60 PIXEL 2007 OF oDlg

   ACTIVATE DIALOG oDlg CENTERED
 

Just specify the file name like any bitmap/image file. FWH will take care of all that is needed.
This feature was availabe for many years

Till FWH2206, we need to specify an existing file,
From FWH2210, it is enough if we specify dot ext , eg: ".DOCX", ".PDF", etc. , but limited to sizes 16x16 a,nd 32x32 only

Cool! I didn't realize it's already available.
Thanks Rao!
